Black technology, starting from daily check-in

The interior of the crystal pyramid is not as dark as imagined, but filled with bright white light spots like a galaxy.

These white light spots, like stars, float in the cave, exuding a soft light.

Under the shining light, the situation in the cave can be seen at a glance.

After Lin Yu observed carefully for a while, he found that the cave was a structure similar to a secret room.

Its surroundings are all made of crystals.

Even the floor.

And in the center of the floor, there is a huge circular hole.

Because it is too far away, Lin Yu can't see the scene inside the big hole.

However, even so, according to Lin Yu's guess, this big hole should be related to the black vortex formed outside.

As for the white spots in the sea water, they should be some kind of ancient and unknown plankton.

Other than that, there is nothing left in this chamber.

Moreover, it is worth mentioning that there is no undercurrent in this secret room, and it looks very safe.

Completely and the violent undercurrent environment outside formed two extremes.

"Go to the big hole in the most central position, it should be possible to go down there."

Looking at the scene in the picture, Lin Yu took the lead in ordering.

Hearing this, the staff carefully controlled the unmanned tactical mech to fly over.

Soon, the unmanned tactical mecha came to the big hole and activated the multifunctional weapon system.

As the metal parts on the arm continued to expand, extend, and deform, a super-large-diameter long-range spotlight was slowly revealed.

"Pong!"

When the long-range light is activated, a dazzling white beam of light shoots out directly, emitting a huge light in 360° without dead angle.

For a moment, the entire secret room was as bright as day, and there was a vast expanse of whiteness everywhere.

Very clear.

And the scene inside the big cave is also fully revealed under the illumination of the white beam of light.

This big hole goes directly to the ground. At first glance, it is at least a hundred meters long, like a straight passage.

And the bottom one is a huge mechanical platform.

In the center of the platform stands a huge and hideous muzzle.

Obviously, this should be the intermediate laser weapon Lin Yu is looking for.

"Mr. Lin, this thing should be the key technology we are looking for, right?"

Looking at the huge muzzle tens of meters wide in the picture, He Weiguo asked with a frown.

"It's about the same. I didn't expect it to be the only one left in the ruins. Time is really merciless."

Lin Yu nodded, with regret in his tone.

Originally, he wanted to send people from above to find the other four submarine pyramids and explore the ruins inside.

It turns out this is redundant.

Because the time is too long, apart from black technology like mid-level laser weapons, there should be nothing left.

"In this case, let's go down first and see if we can dismantle this thing, and then let the Periscope transport it back."

After confirming the target, He Weiguo ordered people to act immediately.

It's just that it's not waiting for the staff to start manipulating the unmanned tactical mecha.

In the picture, the originally calm and huge muzzle suddenly lit up with a misty white light.

Seeing this, Lin Yu suddenly felt bad, and quickly wanted to evacuate the unmanned tactical mecha.

However, before he could open his mouth, the white light flashed away, and then soared into the sky!

next second.

As the sea water continued to boil and frantically bubbled, a terrifying column of air rushed out from the bottom of the sea, reaching the secret room where the unmanned tactical mecha was located almost instantly.

Under the sudden attack of this airflow column, the unmanned tactical mech was like a toy, being swept in by the violent airflow without any resistance.

In the end, the violent air flow, wrapped in the unmanned tactical mech, roared into the huge black vortex outside.

“Zizzizi~~”

The last picture from the unmanned tactical mecha was a frantically rotating lens and countless sundries crushed by the pressure of the seabed.

For this sudden scene, except for Lin Yu, everyone was stunned, with a dumbfounded expression on their faces.

There is no way, the speed of the white light just now was too fast.

They didn't react at all.

In the blink of an eye, the originally good unmanned tactical mech was scrapped.

It was so sudden.

"Mr. Lin, what's going on? Why did the fort on the bottom of the sea suddenly start?"

After recovering, He Weiguo looked at Lin Yu immediately, trying to figure out the problem.

Others also shifted their gazes.

Facing everyone's doubts, Lin Yu did not answer directly, but ordered the staff unhurriedly: "Let the other two unmanned tactical mechas enter the crystal pyramid."

"This……"

Hearing this order, the staff hesitated for a while, and subconsciously looked at He Weiguo.

"Do as Mr. Lin says,"

He Weiguo waved his hand, his tone was indifferent, without any unhappiness.

Although he is the person in charge of this operation, Lin Yu is the real expert.

Professional things should naturally be handed over to professional people.

Since Lin Yu has said so, there must be a reason for him.

As chief, he just needs to take, and accept, the advice.

What's more, this is Lin Yu, even if what he said is wrong, it's okay.

Isn't it just the loss of two unmanned tactical mechs?

As long as Lin Yu is willing, he can set off this thing as a firework.

"Yes!"

After receiving the order, the staff acted quickly.

Soon, the two unmanned tactical mechs that were on standby in the undercurrent area instantly switched on the extreme speed mode and flew towards the inside of the crystal pyramid.

After half an hour.

Two unmanned tactical mechs, one on the left and one on the right, respectively entered the interior of the crystal pyramid.

In the screen, two different scenes were switched out.

On the left is the secret room that the first unmanned tactical mech entered. Now, in the big hole in the center, a terrifying air column is continuously erupting.

On the right is a secret room that has never been entered, and its structure is exactly the same as the one on the left.

However, the big hole in the center of it is peaceful.

Looking at the two completely different scenes in the picture, Lin Yu said slowly: "If I guess correctly, the intermediate laser weapon at the bottom of the crystal pyramid should be in a semi-activated state all the time."

"However, this state is very unstable, so it doesn't last long, and there will only be a slight leak of energy, which is the white light we just saw."

"This white light is a laser. I think everyone knows about its speed and power, so I won't go into details."

Speaking of this, Lin Yu paused and continued to explain: "The two big holes we see now have the same structure, but the only difference is that every once in a while, the energy leaked from the submarine laser weapon , will pass out from these two big holes one by one.”

"That is, when the hole on the left explodes with energy, the hole on the right is safe, and vice versa."

"Of course, there is a time for this energy burst, so as long as the time passes, the unmanned tactical mecha can reach the bottom of the sea and find the control center of the laser weapon."

When Lin Yu finished speaking, in the big hole in the secret room on the left, the energy that was still erupting crazily suddenly weakened and finally disappeared.

at the same time.

The big hole in the secret room on the right, which was originally calm, suddenly exploded with energy at a very fast speed, completely seamless.

"Start the timing from now, and then calculate the duration and interval of the energy burst. Multiple groups of comparisons are required, and multiple calculations are required until the data is unified before and after, without any errors."

"Remember, there must be no errors, otherwise, if the unmanned tactical mecha fails, the dragon mecha of Group B will take over."

"If the dragon mecha in Group B misses, I think you all know what the consequences will be."

Lin Yu explained to the staff with a serious expression.

"Understood! We promise to complete the task! There will never be any error!"

Feeling the meaning of Lin Yu's words, the staff members looked awe-inspiring and shouted firmly.

The failure of the unmanned tactical mech was fine, no one was injured.

And in the cockpit of the Jiaolong Mecha, there is a pilot.

If the same fails, the people inside will be crushed into meatloaf by the terrifying seabed pressure just like the dragon mecha.

Even, because the Jiaolong Mecha is equipped with Suirenshi, it will cause a huge submarine explosion.

This is a very bad thing.

So, for the next half hour.

The staff cheered up and began to observe and calculate with concentration and count all the data.

Finally, after countless deduction by artificial intelligence, a conclusion is drawn.

The time for each burst of energy is 3.747 seconds, and the interval is between 0.012 and 0.015.

In other words, the unmanned tactical mecha must complete the steps of starting, sprinting, and stopping within 3.5 to 3.6 seconds, and finally arrive at the location of the laser weapon at the bottom of the crystal pyramid.

If it is 3.7 seconds, then it is estimated to be dangerous.

"Okay, now that the data has come out, I'll leave it to you guys. Come on, I believe you can succeed."

Lin Yu encouraged with a smile.

Then, under the command of He Weiguo, the staff nervously started the operation.

Although the unmanned tactical mecha has a brain-computer connection with the staff, it only needs a thought to convey instructions.

However, this also requires the staff to calculate in advance the signal delay of the unmanned tactical mech, the delay of program instructions in the body, and so on.

Although these errors are very small, less than 0.1 seconds each time, you don't need to care about them at ordinary times.

But it's different now, every millisecond is a race against time.

This requires extreme concentration.

After a while, the staff adjusted their mentality and started the operation.

In the picture, as the first burst of energy erupts from the left chamber, the unmanned tactical mech in the right chamber is shocked, and directly turns on the extreme speed mode, and dives towards the bottom of the pothole!

1 seconds!

The unmanned tactical mech dived down to a distance of 120 meters!

2 seconds!

The distance has come to 260 meters!

At this point, the distance to the bottom-level intermediate laser weapon is more than halfway!

3 seconds!

390 meters away!

At this time, the ferocious muzzle was already close to Chichi, and the diameter of tens of meters wide was like a huge mouth of a dark abyss, emitting a faint cold light.

3.67 seconds!

The unmanned tactical mech finally reached the bottom floor, and both feet touched the crystal floor!

at the same time.

Just after the unmanned tactical mecha landed, a dazzling white light burst out suddenly, like lightning and thunder, and it disappeared in a blink of an eye.

Afterwards, the surrounding sea water boiled, and a terrifying column of airflow soared into the sky, going upstream against the current, and hitting the topmost floor!

"Pretty!"

"Great, finally arrived safely!"

"Good job!"

Looking at the safe and sound unmanned tactical mech in the picture, the nervous crowd suddenly couldn't help cheering.

Lin Yu also nodded with a smile on his face.

With the lessons learned from the past, the second unmanned tactical mecha will be much simpler.

It also successfully reached the bottom layer on the other side within the limited time.

On the bottom floor here, there is also a mechanical platform and a huge and hideous muzzle.

Under Lin Yu's command, the two unmanned tactical mechas turned on the long-range lights and started the detection work.

These two bottom floors are very large, very empty and barren.

Except for the mechanical platform in the most central position, there are almost no real objects around.

However, it is worth noting that at the corner of these two spaces, there is a broken secret passage.

This secret passage is very hidden, filled with various green algae, like a green carpet.

If it weren't for the artificial intelligence calculation and analysis that the green algae in this corner is more than that in other areas, I am afraid that this secret passage may not be discovered.

"If my guess is correct, these two areas should be connected, and below is the energy supply area and control center of the laser weapon."

Looking at the scene in the picture, Lin Yu made a guess.

After listening to Lin Yu's analysis, the staff drove the unmanned tactical mech to the dark passage and removed all the green algae covering it.

Suddenly, a crystal hole more than two meters wide appeared in the picture.

At this time, the surroundings of the cave were covered with thick green algae.

With the size of an unmanned tactical mech, it is impossible to enter this secret passage.

Therefore, only local methods can be used.

That is violent demolition.

Although it was on the bottom of the sea, the resistance was very high, but in the face of the absolute strength of the mecha, the hole was easily widened.

ten minutes later.

Two unmanned tactical mechs came to the end of the tunnel.

There is a dilapidated metal gate that is only a third of what remains, and it is also covered with thick green algae.

These green algae hang down, forming a thick green gate.

Seeing this scene, Lin Yu was refreshed.

This is the first time that something other than a laser weapon has appeared.

Although dilapidated, this is enough to prove that there is something inside.

While Lin Yu was watching intently, two unmanned tactical mechas passed through the metal gate and entered a super large underground space.

After entering, what catches the eye is the giant floating energy device in the center, and the thick energy pipes connecting up and down.

This giant energy device is oval in shape, fully hundreds of meters wide, and there are four giant black rings rotating slowly around it.

On the ring, there are dense inscriptions engraved in seals. No matter the texture or shape, people are amazed at the perfection of its structure.

And under the energy core, there are still many consoles, covered with green algae, it seems that it is almost scrapped.

"Squaw!

! ”

Just as everyone was immersed in the energy core device, a sharp strange cry suddenly sounded.

next second.

A black shadow suddenly struck from behind the unmanned tactical mecha!

This sudden change made everyone present stunned.

The staff even subconsciously manipulated the unmanned tactical mecha to avoid it, and shone the long-range light on the attacker.

Under the strong light, the assailant not only revealed his true colors, but also burst into shrill screams.

It's a hairy humanoid with sharp claws and a fish-like gill structure on its face.

It can be said that this peculiar amphibian humanoid is a brand new species that has never been found in the world.

Of course, except for Lin Yu who has seen it, everyone present is very surprised.

"Hey, what is this thing, with the gills of a fish with a sharp mouth, and it looks so human?"

"Is this thing a creature in the ruins? It can breathe underwater."

"I don't know if there is a chance to bring it back for dissection and study. This should be a good medical specimen."

"It's sensitive to light, you see, it seems to be crazy."

Amidst the discussion of the crowd, the strange creature stimulated by the strong light seemed to go crazy, screaming in pain, and slammed into the surroundings indiscriminately.

For a moment, the sea water rolled over, and the surrounding consoles were completely destroyed, turning into a pile of scrap iron and crystal-like parts, wires, and lines.

"Stop it quickly, it will be trouble if it touches the main console."

Lin Yu said calmly.

The voice just fell.

Not waiting for the staff to start taking action.

Coincidentally, the console that this weird creature hit next happened to be the main console!

drop!

!

With the piercing siren sounding, a striking red light suddenly began to flash on the main console.

Then, at the very center, the energy core device that was originally floating in the air was instantly activated.

The four black rings began to rotate crazily at a speed visible to the naked eye, wisps of white light continuously overflowed from the core, and then gathered together to form a white light cluster.

Initially, the white light cluster is still very mild.

However, in less than three seconds, as the volume of the white light cluster continued to expand, the original soft white light seemed to turn into a burning white flame.

Hot!Hot!

Under this abnormally high temperature, the surrounding warm sea water immediately began to boil, and a large number of bubbles appeared.

Gululu Gululu~!

"Let's go, get out of here, and come back when the laser weapons subside."

After seeing this scene, Lin Yu gave the order without hesitation.

Hearing this, the staff did not dare to delay, and directly asked the unmanned tactical mecha to turn on the extreme speed mode, and ran towards the direction it came from.

After three seconds.

The unmanned tactical mecha rushed out of the tunnel without a single pause, and went straight to the top of the crystal pyramid.

Since the laser weapon has been fully activated now, the law of energy explosion just now has been broken.

Therefore, the unmanned tactical mecha can fly without any scruples.

However, when the two unmanned tactical mechs came to the top floor and wanted to leave, they found that the undercurrent area outside the big cave still existed!

What's more, the number of terrifying undercurrents is even more than the one at the beginning!

Even if the unmanned tactical mecha has an extreme speed mode, it will probably take at least an hour to leave this ghost place with difficulty.

"It's over, it's useless to run any more, this place has become a restricted area, you can't get in or get out."

"Unless another entrance to the underground space can be found, however, it is too late now."

Lin Yu shook his head helplessly.

Since the weird creature will appear here, it means that there must be other entrances, which can not be affected by the undercurrent area.

Otherwise, that weird creature would not be able to enter here.

However, I wasted a lot of time just running out of the ground, and now I want to go back, it is impossible.

After listening to Lin Yu's analysis, the staff gritted their teeth and turned back.

However, when the unmanned tactical mecha came to the bottom floor, the mechanical platforms in the two separate areas merged at some point, forming a huge muzzle nearly [-] meters wide!

Immediately afterwards, an extremely bright white light began to light up slowly from the mouth of the ferocious giant cannon.

In an instant, a white sun seemed to rise from the bottom of the sea, and terrifying energy began to erupt, emitting extreme light and heat.

Rumble rumble rumble~~!

!

Amidst the huge roar, the entire crystal pyramid began to shake violently.

The strong vibration, like the eruption of a submarine volcano, shakes the earth and shakes the mountains, and the sand is flying.

And at a certain moment, the white light seemed to reach a certain critical point, directly turning into a [-]-meter-thick blue-white beam of light, soaring into the sky from the top of the crystal pyramid, breaking through the sea, and straight into the sky!

Under this beam of Optimus light, the huge black vortex above the crystal pyramid was instantly washed away, and the countless sundries inside were all wiped out!

On the sea level, strong winds raged, raging waves rolled, and water mist flew up, setting off huge waves that shook the sky.

In the atmosphere, large expanses of sea of ​​clouds were torn apart by the blue and white beams of light, revealing a vast and deep blue sky and sparkling stars.

All of a sudden, this sea area was full of visions, massive and magnificent.

at the same time.

The live images of the two unmanned tactical mechas all disappeared.

Terrible geometric changes have taken place in the surrounding magnetic field, and the command center has been unable to contact all units in the Bermuda Triangle waters.

"Mr. Lin, the Flood Dragon Mecha is so far away from the Crystal Pyramid, so nothing will happen, right?"

Facing this sudden situation, He Weiguo frowned, turned to look at Lin Yu, and asked.

Lin Yu took a sip of tea calmly, and said calmly: "Don't worry, there should be only the unmanned tactical mechs that have wiped out the entire army."

"However, the current movement is too big, and I am afraid it will not be long before it spreads all over the world."

"So, after the laser weapon calms down, you should transport it back as soon as possible. After all, it is far away from us. If there is an accident on the way, it will be very troublesome."

"Of course, you don't have to worry about whether the laser weapon will explode again, because it has used up all its energy just now."

"In addition, after such a long time, the various systems should not be far from being scrapped. Now that the final blow is released, it is basically a pile of scrap metal."

"As long as it is not dismantled, it can still be repaired and used when it is shipped back."

With that said, Lin Yu drank the last sip of tea, got up, and said goodbye to everyone.

"Well, the exploration of the crystal pyramid is basically over."

"I'll leave the rest of the finishing work to you. I'm still busy with the research and development of Luan Niao, so I'll leave first."

After finishing speaking, Lin Yu waved his hands, and under the eyes of everyone sending him off, he left the command center without looking back.
