Black technology, starting from daily check-in

After finding the target, Lin Yu quickly fell down.

Because it is located in the tropics, it is hot all year round and accompanied by heavy rainfall.

Therefore, the air is very stuffy, basically like a sauna room with tens of degrees.

In addition, this kind of weather happens to be a breeding ground for various viruses and bacteria. If a person is accidentally injured in such a place, ordinary people will not be able to survive at all.

However, for Lin Yu, who is wearing a nano-armor and has a lot of knowledge of wilderness survival, it is not challenging at all, just like a dimensionality reduction strike.

Soon, passing through the dense canopy at the top of the rainforest, Lin Yu landed under a rosewood tree with a crown diameter of more than 8 meters.

Because the vegetation in the tropical rainforest is extremely rich, in order to survive, the plants need to grow up desperately to carry out photosynthesis and survive.

Therefore, when Lin Yu came to the ground, the dense vegetation covered the sky, almost blocked 99% of the sunlight, and the surface was almost dark.

Especially in this gloomy weather, the originally dense rainforest is even more quiet and dark.

Even the chirping of insects and birds has disappeared, giving people an inexplicable sense of fear.

It can be imagined that in this dark and silent rainforest, when those strange vines appear in front of your eyes, the sensory stimulation and psychological panic are enough to make anyone feel depressed and collapse.

Even Lin Yu feels inexplicably terrified in this kind of place.

So, after taking a deep breath, Lin Yu seemed to think of something. He didn't care about the pear tree in front of him for the time being, but flew to the dense canopy.

Then, with a thought in Lin Yu's mind, the nanorobot on his right hand began to deform and extend, instantly turning into a two-meter long silver knife.

In the next second, Lin Yu's figure turned into a ray of light under the extremely fast jet of the propulsion wing, and disappeared in place in an instant.

"Boom~~"

With the sound of trees collapsing, in an instant, the dense tree canopy with a radius of 20 meters around Lin Yu was cut off by Lin Yu with a single knife.

And the originally dark rainforest also suddenly appeared a bright area.

"Well, sure enough, all the fear comes from the lack of firepower."

Amidst the sound of trees collapsing, Lin Yu looked at the gloomy sky with light rain falling overhead, and nodded in agreement.

After dealing with this small matter, Lin Yu returned to the ground, turned his eyes to the pear tree, and began to deduce and calculate.

Soon, a detailed plan appeared in my mind.

Without much thought, Lin Yu picked up the long knife and walked towards the pear tree.

While Lin Yu was busy making the wooden cabin door, the light rain that started to fall became heavier and heavier, and finally turned into a torrential rain in the howling wind.

Not only that, but the moisture and humidity in the air has become more and more dense, and now it has begun to fog.

5 minute later.

Under the systematic wilderness master skills, Lin Yu successfully used the mortise and tenon structure to splice two thick rosewood boards together to make a wooden cabin door that meets the requirements.

However, just as Lin Yu was about to leave with his things, a black shadow came from behind at a high speed.

"Oh!"

Just when the black shadow was about to fall behind Lin Yu, Lin Yu, who turned on the super brain, reacted instantly, turned around sharply, and grabbed the black shadow tightly in his hand.

Taking a closer look, after finding that the thing in his hand was a fist-sized stone, Lin Yu seemed to think of something, and quickly looked at the source of the stone.

"Whoosh."

Under Lin Yu's gaze, an unknown black shadow disappeared instantly in the misty rain.

After seeing this scene, Lin Yu couldn't help frowning.

Things that can still wander outside in this environment must not be normal animals.

Because normal animals have already made precautionary preparations in advance of the storm.

Moreover, it should be an ape who knows how to use a stone to test, and the strength is so great.

However, what Lin Yu couldn't figure out was how could there be apes living in groups in this kind of place?

Although this does not rule out the possibility of such creatures on uninhabited islands.

But the problem is that on this uninhabited island, Lin Yu just didn't hear or see any sounds of apes or traces of their lives.

"call out."

Just as Lin Yu was thinking, another black shadow came from behind at high speed.

For this sudden sneak attack, Lin Yu, who had been prepared for a long time, did not take any action, but turned around quickly, letting the stone hit his iron-hard nano armor.

As for himself, he fixed his eyes on the source of the stone.

This time, Lin Yu finally saw the shadow of the attacker through the white mist.

However, what surprised Lin Yu was that the attacker was not like a chimpanzee or ape-like primate, but very similar to a human being!

It can be said that, except that the whole body is covered with black hair, it looks like a human walking upright!

Just as Lin Yu was in a daze, the black shadow seemed to realize that he had been discovered, and with both hands and feet, he ran quickly towards the dark place.

Seeing this, Lin Yu also quickly came to his senses, put the wooden cabin door into the memory chip, and quickly chased after him.

Because it's raining heavily now, and it happens to be foggy, in order to prevent losing the shadow, Lin Yu's flying speed is not fast, but he just hangs behind and follows it tightly.

Black Shadow, on the other hand, was very familiar with this place, so he harassed Lin Yu in various ways during his escape.

However, its harassment has no effect on Lin Yu who is wearing nano armor.

Soon, the two chased and fled, and before they knew it, they reached the highest point of the mountain.

Looking at a cave in a certain rock wall on the mountain peak, the black shadow quickly climbed over the smooth and wet rock like flying over a wall without any hesitation, and then ran into the cave.

At the same time, at the moment when the black shadow rushed into the cave, Lin Yu also rushed out of the dense jungle and saw this scene.

Suspended in the air, looking at the cave on the stone wall, Lin Yu also smiled.

Good guy, isn't this just catching a turtle in a urn?

Without thinking much, Lin Yu flew straight to the cave in the stone wall.

When he came to the cave and looked at the dim scene inside, Lin Yu thought for a while, as if he remembered something, he took out a super powerful flashlight directly from the sundries of the storage chip.

"Pong."

With the activation of the super flashlight, a dazzling white light suddenly appeared in the cave.

For a moment, the originally dark cave suddenly brightened like daytime, and there was a vast expanse of whiteness everywhere, which was very clear.

Even the dark space at the end of Lin Yu's sight is illuminated, revealing a turning passage.

"what?"

Looking carefully at the surrounding caves, suddenly, Lin Yu let out a light snort, and soon found a clearly visible pattern at the top of the cave.

The outermost circle of this pattern is a six-pointed star, and the inner circle is two concentric circles.

As for the innermost part, there is a trident, and the three overlap each other, which seems to have an inexplicable charm.

According to the traces and clarity of the pattern, Lin Yu can easily judge that it should have been painted in the last few days.Valley

Moreover, it seems to use some kind of sharp claws.

Obviously, this should be the masterpiece of that black shadow.

"This pattern..."

Staring closely at this weird pattern, Lin Yu frowned, and quickly began to search for various information related to it in his mind.

Especially the innermost trident pattern, which is the most obvious clue.

Because in the sea, the trident means Poseidon, he is the god of the sea in ancient Greek mythology, who controls the power of the sea.

However, what Lin Yu didn't expect was that he searched all over his knowledge base, but he didn't seem to find any information related to this icon.

There is no way, Lin Yu can only keep this pattern in his heart temporarily, and then continue to walk into the cave.

As for why he didn't use another god-level skill [Witness of Civilization], it was because it was of little use.

After all, [Witness of Civilization] can only trace back how the pattern was formed, and cannot tell him what the pattern means.

1 minute later.

Lin Yu came to the deepest part of the cave.

It's just that what makes Lin Yu feel wrong is that he finds that the cave seems to go straight down.

Not only that, the originally dry cave suddenly became wet.

Even Lin Yu smelled a strong smell of sea.

Obviously, this is a reflection of increased humidity and moisture in the air.

In other words, if nothing unexpected happens, then the end of this cave seems to lead to the bottom of the sea.

Thinking of this, Lin Yu couldn't help speeding up his flight.

Soon, as the smell of sea in the air in the cave became stronger and stronger, Lin Yu finally came to the end of the cave.

Sure enough, as Lin Yu expected, there is really a sea of ​​waves crashing under the cave.

And the black shadow just now, apart from leaving a string of wet footprints similar to human beings on the ground at the end of the cave, has long since disappeared.

Seeing this, Lin Yu was also a little helpless.

Originally, he thought that he was a catch in the urn, but he didn't expect that the clown turned out to be himself.

However, it can't be his fault.

After all, who knew that the deepest part of this cave actually leads to the sea.

After sweeping his eyes across the sea area below, Lin Yu squatted down and carefully observed its footprints.

Under Ultrain's calculation, Lin Yu soon discovered that this footprint was different from that of human beings.

The footprints showed that its toes seemed to be connected together, which looked very much like a flipper.

This kind of webbed feet, found only in some amphibians, reptiles, birds and mammals, is specially used to repel water.

It's just that Lin Yu has just seen that it can crawl on smooth and wet stone walls like walking on flat ground.

Therefore, if it is this kind of flipper, it is impossible to fix it on the wall.

Unless, there are hidden barbs on its feet, or structures like suction cups.

Because only in this way can it crawl quickly on the wall.

Therefore, according to the existing information, Lin Yu quickly sorted out a piece of information about Sombra.

That is, it should probably be an amphibian, and look very human-like, able to walk and crawl upright.

It's not the human beings who fell on the uninhabited island, or the savages that Lin Yu first thought of.

Besides, this uninhabited island should have been discovered not long ago.

This can be seen from the clearly visible pattern at the entrance of the cave.

However, what puzzles Lin Yu is why such a non-human animal knows the pattern mark that only human civilization can understand.

Is it a coincidence?Or on purpose?

"Pfft."

Just as Lin Yu squatted down and meditated, suddenly, a slight sound of water rang out in the sea area of ​​the cave below.

Hearing this abnormal movement, Lin Yu suddenly regained his spirits, quickly activated the propulsion wings, and the whole person came to the sky above the cave sea area in an instant.

Soon, he saw a dark shadow beside a big rock.

Seeing this, Lin Yu didn't hesitate at all, just like a javelin, he directly plunged towards the sea area below.

And almost at the same time as Lin Yu made some moves, the black shadow observing the situation under the sea quickly came back to his senses and swam desperately downward.

Soon, Lin Yu came to the dark seabed, and saw a black figure not far away who was doing breaststroke with his legs.

Since the nano armor comes with oxygen supply properties, Lin Yu doesn't need to worry about underwater breathing.

Moreover, even the flying speed that was originally worried about can go all out under the sea.

Therefore, looking at the black shadow that has dived hundreds of meters in a short period of time, the corner of Lin Yu's mouth curled up.

In the next second, with four pulse waves spraying from behind at a high speed, Lin Yu, who was fully fired, caught up with the shadow almost in the blink of an eye.

This time, with the help of a super flashlight, Lin Yu finally saw the face of the shadow clearly.

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

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

"Hiss!!"

Just as Lin Yu was observing, the humanoid under the illumination of the super flashlight covered his eyes in pain and let out a miserable scream.

Faced with this unprecedented stimulation of strong light, it seemed to go crazy, and desperately swam towards another direction, and its speed increased sharply.

Seeing this, Lin Yu came back to his senses and did not continue to chase. Instead, he shone a super flashlight on it and watched it leave.

However, what Lin Yu never expected was that when he shone the super flashlight in the direction of the humanoid animal, he was deeply shocked by the picture at the end of the flashlight!

In Lin Yu's sight, he saw a huge broken pyramid standing majestically in the deepest part of the seabed!

Not only that, beside the broken pyramid, there are huge stone buildings lying quietly on the bottom of the ocean!

They are compact in structure, large in scale and changeable in shape.

According to Lin Yu's visual inspection, the largest concentric stone wall is astonishingly long as about 1600 meters!

And on those stone-paved streets, there are also rectangular or polygonal stones arranged in various patterns.

At this moment, the ancient ruins that were originally sleeping in the deepest part of the sea finally showed the glory of an ancient civilization to the human beings in the new era!
