Survival on the Star Sea: Starting from a small broken ship and becoming stronger

Zhao Feng, who has the advantage of the location, only needs to attack them when they get closer to 1-2 meters.

At this time, there are completely two views inside and outside the passage.

In the passage, dozens of zombies that poured in were first pierced from head to tail by an energy beam, and then the energy exploded, blasting all the zombies that were still lining up at the entrance slope into pieces and flying away.

Immediately afterwards, the zombie in the passage was ignited due to the wound. The fire quickly expanded and spread to the whole body, and was burned to ashes in a short time.

Outside the passage, the upward-slanting exit will spit out flames several meters long every once in a while.

Along with the flames, there were also a large number of broken limbs torn into pieces by the explosion.

Many zombies that were still approaching stupidly were directly smashed into sieves by the sprayed flesh and bones.

In his current state, zombies and the like are no threat at all.

While the zombies are being eliminated, the system is also constantly sending good news of increased experience points. . .

Every time you pull the trigger, dozens of experience points will be recorded in your account.

[Experience value +1] x39, [Experience value +1] x27, [Experience value +1] x36

Stimulated by such a beautiful sound, Zhao Fengshuang couldn't stop at all.

It didn't take long for him to kill more than 1,000 zombies.

It stands to reason that there is no way this passage can hold so many corpses.

But in fact, the body that was quickly ignited burned out quickly, and the ventilation holes that had been installed in the room a long time ago ensured sufficient oxygen.

Of course, this defense system is not perfect, and there are still many problems.

After half an hour, the flaws in the design gradually became apparent.

The first thing to cause trouble was the half-meter-thick iron plate passage. Its thermal conductivity was really strong, just like running a stove.

After half an hour of burning, the temperature in the safe house had risen to 32°C.

And it's still rising.

Additionally, a foul smell permeated the entire space.

Even if the ventilation holes are constantly filled with fresh air, it cannot be dispelled.

The longer the smell lasted, the more disgusting it became.

There is no way, the zombie's body is not all grease, there are also internal organs and bones.

The flame needs to completely evaporate the moisture in it before it can be completely burned.

There will definitely be a lot of smoke produced during this period.

Among them, the lighter ones will float away, the heavier ones will sink, and the slightly more active ones will spill out in all directions.

This gas is designated poisonous without even thinking about it.

If these two problems are not solved.

In another half hour to an hour, the zombies may not be needed to break through the defense.

They will be the first to be smoked into smelly meat, or fried into teppanyaki.

that's the truth.

More than 10 minutes later.

At this time, Zhao Feng's eyes were already red from the smoke, and he was no longer as proud as before.

Li Ruolan was even worse. She fell to the ground at some point and was breathing heavily.

This situation made him know that he could not continue like this.

Glancing at the remaining power of the drilling laser.

【78.25%】

'Dry! Fight! ’

Turning his head, he first fired two bursts to kill the zombies crawling over.

Then he neatly carried the drilling laser behind his back, went to the side and pulled out the heavy latch.

He raised his hand and grabbed the handle, and slowly pushed open the wall that was more than ten centimeters thick.

The side door he and Li Ruolan came in before was a secret passage.

And the wall he is pushing open now is, in a sense, the real "front door".

The purpose of opening the front door is simple, to clear the passage.

Ultimately, the source of the poisonous gas is the burning corpses, and they are also the source of the high temperature.

As long as the channel is cleared every once in a while, poisoning can be completely avoided.

Of course, the risk of this operation is very high.

But compared with chronic death, some danger is nothing.

The protagonist of the cleanup mission is still the S-shaped drilling laser in his hand.

Relying on the energy surface sprayed in its default mode, it can completely clean out the remains of corpses on the ground, poisonous gas and poisonous dust in the air.

It can be regarded as fighting fire with poison and extinguishing fire with "fire" in a sense.

As the door was fully opened, a hot and foul smell came out.

What came into view was a purgatory-like scene.

The passage originally made of iron plates had now turned into a corridor of flames.

The bones on the ground continued to make "crackling" explosions in the flames.

The originally pitch-black wall was burned red, and pitch-black poisonous mist billowed above the head.

Resisting the discomfort, Zhao Feng adjusted the drilling laser to the default mode.

Accompanied by bursts of buzzing sounds, an arm-thick red beam erupted from the muzzle,

The light beam sprayed out for half a meter and gradually expanded and spread. The bound plasma quickly formed a familiar energy surface and completely enveloped the channel.

The burning bones at the door, the poisonous smoke, and even the stinky poisonous gas in the air were all annihilated or pushed away by the super-powerful energy.

Taking a deep breath, Zhao Feng stepped into the passage.

As soon as he entered, a violent heat wave came from all directions and enveloped him.

The human respiratory system simply cannot bear this level of heat wave.

In this high temperature environment, if you dare to breathe, your nose, pharynx, respiratory tract and even lungs will be instantly burned by the hot air, causing congestion, edema, and then ulceration.

At the same time, the respiratory system will be stimulated to this degree, which will produce an uncontrollable physiological reaction.

This causes constant coughing and sniffing, a vicious cycle that leads to death in the end.

Fortunately, Zhao Feng had anticipated it before entering and took a deep breath in advance.

After entering the passage, hold your breath completely.

This crisis has been avoided.

Of course, the harm caused by hot air to the human body is not limited to the respiratory tract.

After entering the channel, body water will also evaporate quickly.

Before he took a few steps forward, a lot of sweat poured out of Zhao Feng's cheeks.

My body was fine, and I was wearing the protective clothing that came with me, which was barely able to withstand the high temperature air near 75 degrees in the tunnel.

But the exposed face and neck were painfully licked by the hot air.

The sweat was evaporated by the high temperature almost as soon as it came out, leaving only strips of salt stains.

The insulating boots on my feet began to melt as soon as I stepped on the iron plate.

No matter how you look at it, there is not much time left for him, so he must fight quickly.

The only good thing is that the resistance caused by these bones is completely incomparable to the soil and mineral layers.

Zhao Feng moved forward almost at a jogging speed.

10 seconds, it only took him 10 seconds to completely clear the passage, and it became clean instantly.

Then he stepped back without hesitation.

However, the zombies outside would not let him retreat so easily.

The zombies that came in again howled wildly, ignoring the high temperature in the passage and the energy barrier between them, and rushed towards Zhao Feng desperately.

Ignoring the high temperature, the most they can do is lose some flesh and blood.

Ignoring the plasma ejected by the drilling laser will cause their corpses to be wiped out in an instant.

After retreating all the way, ordinary zombies did not cause much trouble to him except for bumping into him and receiving a wave of lunch boxes.

It wasn't until the worm zombies entered that Zhao Feng became a little more vigilant.

After they entered the tunnel, they opened their ring-shaped mouthparts full of tiny teeth.

After a brief pause, his abdomen suddenly contracted, spitting out a large amount of acid in his direction.
