Perhaps it was because the vegetation was too dense, the air was too humid, the water in the atmosphere was too abundant, or perhaps it was because the indifferent world wanted to give Chen Feng a warm welcome gift, the heavy rain kept falling.

With his physique, he didn't have to worry about catching a cold after getting wet. He put his hands in his pockets and walked slowly towards the run-down town he had discovered earlier in the rain.

Although for him now, it actually didn't matter where he lived, since he was alone anyway.

But in his subconscious, he still wanted to live in a town.

He didn't expect to meet other living people.

Even if he only found a photo of a stranger in someone else's abandoned room, it would be more human.

As he walked and thought about the problem, the cool rain gradually extinguished the fire of anxiety in his heart, allowing him to analyze the current situation more calmly.

Chen Feng first formulated a relatively simple plan.

Although he had no hope that there were other humans on the earth, he certainly could not stay in one place forever.

He must keep moving and try his luck in more places.

If he could meet other people, of course it would be good.

But even if there is no one, as long as he can pick up something useful, it will be fine, commonly known as turning into a garbage man to pick up garbage.

Now the whole earth belongs to him, no one is fighting for it, and he can use whatever he can pick up.

First of all, he has to solve the problem of living and moving. It is definitely not possible to rely on legs all the time, and the efficiency is too low.

If he wants to explore information by excavating relics, he also needs the help of tools.

After the preliminary work is almost completed and the tools available are obtained, the next step is to observe and investigate the site and discover as much information as possible.

Although he is not a professional archaeologist, Chen Feng still developed an information extraction plan based on logical thinking.

First, by analyzing the current situation, simply and roughly guess and calculate the highest technological level of human civilization in this failed timeline.

Second, it is also important to determine the time when the destruction occurred. At least we must figure out whether it was 2,500 years ago or later.

Third, by carefully observing the post-war traces and the forms of damage to ships and buildings, try to analyze the means of attack that caused the destruction.

Energy explosion? What type of energy?

Live ammunition bombing? What kind of live ammunition? Nuclear fission? Nuclear fusion? Vacuum bubble? Quark bomb? Antimatter bomb?

Or cutting and tearing? How to cut? Quark cutting? Force field cutting? Space tearing?

Solving this problem can basically answer whether the destruction was caused by human civil war or foreign enemies.

Fourth, by analyzing the functional layout of urban ruins and towns, try to deduce the location of academic cities before the collapse of earth civilization in this timeline.

Fifth, when the first four conditions are difficult to meet, just walk around aimlessly, remember as much information as possible, and arrange a month before October 3020 to think seriously, summarize and analyze, and see what conclusions can be drawn in the end.

This is the dumbest and most helpless way, but Chen Feng feels that this is probably the only thing he can do.

He had realized one thing during his simple patrol before.

The destroyed human cities and ships were not simply destroyed, but encountered truly sophisticated means of destroying civilization.

The energy systems of all ships were completely destroyed, and the biological energy storage cells and suspected antimatter power capsules were also targeted for destruction.

The method of destruction did not seem to be a direct bombardment from the outside, but rather a small combat unit entering the interior and eliminating them one by one.

In addition to the energy core, various small intelligent computer cores equipped with computing cores and information storage media were destroyed. The means of destruction were not conventional physical means, but were suspected to be a high-frequency quantum impact technique, which created an effect similar to the ultra-high frequency electromagnetic interference bombardment used in the information warfare of the battlefield in the 21st century. It was very similar to the electromagnetic interference methods of the spherical battleships that Chen Feng had dealt with many times.

In addition, some things with obvious text and pictures were also targeted for removal.

Including his own tombstone, the memorial stone tablet, the text plaques on the ship's equipment with the performance and parameters of the equipment, and the photo frames in the crew dormitory cabin that were burned to only the frame...

Almost all information carriers that can be regarded as an important part of human history have been destroyed.

These are the information he has collected so far.

He feels very strange.

The purpose of this behavior is similar to that of the compound-eye civilization.

This is one of the very standard methods of destroying civilization. It first eliminates the lives of the civilized race, then destroys its buildings and transportation, and finally erases its information and removes the representatives of the target civilization one by one.

Such a method seemed to be a desperate and ruthless one, but Chen Feng always felt that it was strange and very petty.

With the ability of the compound-eyed civilization, there is no need to do such a targeted and boring thing, it can completely wipe the entire solar system into dust.

Chen Feng vaguely felt that he might have guessed the first answer.

There is a high probability that mankind will once again encounter a catastrophe of mass extinction, but this time it will be defeated by the Z bacteria.

The essence of the mass extinction has changed from humans exterminating animals to animals controlled by Z bacteria exterminating humans and specifically eliminating traces of humans.

But what about Z bacteria? What about animals?

He didn't see them.

And the mass extinction seems terrible, but didn't we win last time?

There is no reason to lose this time.

There are so many contradictions here that he can't come to a conclusion and can only guess.

When it really got dark, he happened to walk to the town he had visited once before.

Climbing to a height of about four floors, he tore off several vines wrapped around the inverted skyscraper, bent down and drilled into the alloy structure house, and then relied on his strong night vision ability to use the faint light to clean up the messy objects in the room that had collapsed.

Luckily, he also found a set of synthetic fiber clothes that could be replaced, as well as two quilts made of the same synthetic material in the room.

Who knows how many hundred years ago these things are, the material is a bit brittle, and it is definitely not as good as the previous combat uniforms, but it is still much tougher than the clothes of the 21st century. As long as he doesn't do anything stupid, it will not be easily damaged and can be used.

With a change of clothes and quilts, he was temporarily satisfied.

It's a pity that the quark machine seemed to be damaged, or it had no energy and could not be used, otherwise he could have prepared a big meal.

When he thought of the big meal, he was really a little hungry.

His stomach was rumbling.

"Stars..."

He shouted out of habit, and then reacted and sighed.

The dark room was empty, with only his sighs echoing.

It was still raining heavily outside.

Although his vision was excellent at night, the rain eventually affected his vision, and Chen Feng didn't know where to find food.

He endured in the room for about half an hour. His stomach was really hungry. Chen Feng gritted his teeth, picked up a broken alloy stick about 1.5 meters long from the ground, walked out carefully, and then slid to the ground.

The heavy cumulonimbus clouds obscured the starlight and the moon, and the farthest visible distance was less than 50 meters.

Fortunately, Chen Feng didn't have to walk too far.

When he came here in the morning, he saw dense animal footprints on the ground, leading to another building far ahead.

Having a strong pictorial memory has its disadvantages, but the advantages are also obvious. It is impossible for a normal person to follow the previous memory to track the footprints at night. Chen Feng's instinct is that of a cat that is good at hunting.

He was looking for prey, and the prey was also looking for him. After groping forward for less than a kilometer, more than a dozen pairs of green eyes quietly appeared under the dense roots of a big tree in front of him.

It's not that these eyes can glow, but the special structure in the pupil has a strong reflective ability, just like holding a flashlight to shine on the eyes of a cat at night.

Chen Feng was not afraid, he just grinned and licked his lips.

He knew what these animals were, wolves.

The rain was still dripping, and Chen Feng pretended to be innocent and slowly approached with his hands behind his back.

The wolves were very experienced and cunning. They all crouched without making any sound, as if they were deceiving themselves, thinking that they had not been discovered by the "prey".

As Chen Feng "boldly" moved forward, the distance between the two sides gradually shrank to less than ten meters.

The green eyeballs began to move quietly, some leaning back. After about ten seconds, Chen Feng completely stepped into the range of the tree roots and was also surrounded by the wolves.

Ao!

If you don't move, you'll be fine. If you move, you'll be extremely ferocious.

More than a dozen wolves rushed out almost at the same time, stepping on the water on the ground, their heads hitting the raindrops, and roaring towards him.

Chen Feng remained calm, but took the opportunity to see the size of these giant wolves.

They were huge, even bigger than the Arctic wolves of the 21st century, with an average body length of nearly two meters, almost like horses.

Chen Feng got new information.

The wolves he saw now, the tigers, horses, hyenas and other animals he had seen before, and the trees all seemed to be proportionally larger than those in the 21st century, which is suspected to be related to the higher concentration of oxygen in the atmosphere.

The tall and giant wolf that rushed the fastest rushed to Chen Feng in less than a second, stretched out its front paws, opened its bloody mouth and bit forward fiercely.

Chen Feng raised the alloy stick in his hand like lightning and stabbed forward.

With a hissing sound, the alloy tube pierced the throat of the wolf.

At the same time, Chen Feng bent down, crawled on his stomach, pulled the alloy tube down with his right hand, propped up his left hand on the ground, exerted force with his feet, and rushed forward several meters, just passing under the giant wolf, and at the same time, took the giant wolf with his throat pierced in the air.

Chen Feng did not turn his head, just exerted force with his right hand, trying to pull out the alloy tube, but failed to pull it out. The giant wolf with his throat pierced actually bit the alloy tube.

There was a sound of breaking air behind him, Chen Feng broke free and discarded the weapon, and began to accumulate strength.

The thick blood and mud in his body were pumped away, and the muscles all over his body were pulled and tightened to the extreme like steel wire.

Then he twisted his body, clenched his fist, pressed his body, turned his head, and threw a hook punch from bottom to top with his right hand.

A punch whizzed out, like a sonic boom.

Countless raindrops splashed from the fist, hitting the soft part of the lower jaw of another giant wolf.

The giant wolf, which was more than two meters long, howled and flew backwards with its head raised.

At the same time, Chen Feng turned around again, kicked out with a whip kick, and the tip of his shoe hit the ear of the third giant wolf.

With a bang, the synthetic shoes he had just changed exploded on the spot.

The giant wolf was kicked sideways in the air and fell miserably to the ground, with blood gushing out of its ears.

Five seconds, three moves, and three wolves fell.

Nearly ten other giant wolves froze on the spot and no longer moved forward.

Chen Feng walked to the side of the leader wolf, who had gradually stopped struggling, and pulled it out easily, holding the alloy tube in his hand again.

The tip of the alloy tube clanged and hit the ground.

The other ten giant wolves quickly ran away with their tails tucked in.

Chen Feng shrugged.

This meal was perfect.

But these animals from the 31st century seemed a bit fierce.
