The war of a hundred years ago brought not only a scarred face to the earth, but also the radiation dust that permeated the surface of the entire planet. Although the impact of radioactive fallout on the earth has been reduced a lot over the past 100 years, it has still caused a lot of damage to people's lifespan.

In this post-nuclear world, the average life expectancy of human beings has basically shortened to more than 40 years. However, even so, the forties are just a stretch of hope for many humans, who are often devoured by other mutated creatures before their bodies are eroded by nuclear radiation.

Without the protection of science and technology, human beings, who have relied on foreign objects to dominate the earth for thousands of years without the slightest evolution of their own flesh, are like lambs waiting to be slaughtered in the face of the invasion of nuclear radiation, and they are completely powerless to fight back.

When other organisms have gradually adapted to the current environment of the earth after generations of survival of the fittest, mutated and even evolved. Human beings gradually degenerate, and the weak body cannot resist the effects of radiation, and the tissues slowly die under the transmission of radioactive elements. Occasionally, normal humans who can withstand the effects of radiation only have a lifespan of thirty or forty years, and their physical strength is only slightly stronger than that of ordinary people.

This is also the reason why Liu Ye was able to easily restrain the patriarch and them that day, such a physique is as fragile as the mouse that everyone on the earth shouted at back then.

Now, Yang Tian and the others are facing a mutant rat species with a body like a fat pig-pig rat. The pig rat did not have the terrifying strength of the boar king, nor its nearly indestructible fur, nor its fangs strong enough to pierce the rocks; However, the same Yang Tian and they do not have Liu Ye's specially trained physical fitness and special skills, and the only thing they rely on is the number of people, twenty-three to one.

It's just that Yang Tian, who hasn't dealt with land creatures for a long time, forgot. In addition to the incomparable position in the hearts of ladies in Liu Ye's time, rats also have a very famous ability - strong reproduction, which makes them survive in the struggle with humans in the previous year, and even when humans have come to this point, they are still tenaciously surviving.

Yang Tian and the others helplessly found that when they thought they had surrounded the pig and rat, after the "squeak" sound, the surrounding grass shook slightly, and more than 20 eyes glowing red suddenly appeared in the dark distance.

Slowly, more than a dozen pigs and rats emerged from behind the more than 20 people, and surrounded them in the same way.

A pig rat can deal with about three people, so more than ten pigs and rats trap them in a surrounding way, plus the pig and rat inside should be combined with the outside. If nothing else, there is basically no suspense about what the outcome will be.

"In just a hundred years, even the most timid rats have evolved to the point where they can use simple tactics. Although it is just instinct, it is a very important step, but what about human beings......" Liu Ye, who was standing from a distance and watching everything, thought quietly.

Yang Tian knew very well in his heart that the pigs and rats gathered but did not attack, on the one hand, because they were instinctively afraid of the torches in their hands, and on the other hand, they were also looking for the best time. If there is no major turnaround, then there is a good chance that the meeting itself will become a meal for these ugly guys.

"Poof!" The sound of a hard object piercing the soft flesh sounded, and a woman from the Sea Serpent tribe could no longer bear the invisible pressure, screamed, and stabbed the spear in her hand towards the pig and rat that was surrounded in the middle.

"Oops!" Yang Tian saw the woman's actions and secretly screamed. I saw that the woman's blow with all her strength did not stab the vital part of the pig and mouse, but only stabbed the left leg of the pig and mouse, and such an injury would only provoke its ferocity even more.

"Squeak~~" The pig and mouse screamed angrily and pounced on the woman.

Yang Tian didn't care much at this time, and shouted: "Everyone gather the torches together and kill the middle one first!" ”

Yang Tian could clearly see through the afterglow of the torch just now, and when the pig and mouse pounced on the woman, they still subconsciously avoided the burning flames to attack. It seems that the torch in his hand still has a mysterious deterrent power for these rats who have not yet possessed true intelligence.

"Die! ~~”

The spear accompanied the anger of the Sea Snake tribesmen into the bloated bodies of the pigs and rats, and although the screams of pain could slightly ease the anger of the tribesmen, they could not exchange for a fresh life. Blood flowed from the woman's body and slowly seeped into the ground, and the woman's throat had already been bitten by pigs and rats.

The woman's hands tightly covered her neck, which was constantly bleeding outward, and her body shook violently, and her eyes bulged outward, as if she wanted to remember the world firmly. However, due to constant blood loss, the color of the world faded in her eyes, and finally it was dark.

Yang Tian looked at the woman on the ground who was slowly motionless, and his heart was full of grief, not only for the passage of life, but also for the re-attrition of the number of tribes.

But this is the battlefield, and nothing just now is willing to kill anyone. In this world where the strong survive and the weak die, everyone must force themselves to be strong, otherwise the slightest mismatch will be a catastrophe.

Yang Tian understood these things better, otherwise he would not have become the patriarch of the Sea Snake Tribe, and he would not have had this hunting behavior.

He had to come for a reason, and since the mysterious man used a strange weapon to kill the two mutated lizards in front of everyone, he knew that only he could get his revenge. What's more, the almost pathological pursuit of strength that everyone in this era has in Yang Tian's heart urged him to carry out this operation in the dark night, when this mutated creature haunts most frequently.

Looking at the pigs and rats that were still hesitating on the periphery, Yang Tian knew that this was just a temporary illusion, and it was impossible for the pigs and rats who had been stimulated by the smell of blood just now to give up the prey in front of them, and the torches could only stop them for a while.

The pigs and rats became more and more restless, Yang Tian knew that the opponent's attack would start soon, and he had to come up with a countermeasure, and it was impossible for them to defeat them alone.

"Solution, I need a way, a way to kill all these abominable creatures!" Yang Tian's brain was running rapidly, racking his brains to find a way.

Suddenly, he noticed the torch in his hand: "Fire, yes." They're afraid of fire, so why can't they be dealt with with a bigger fire? ”

As soon as the inspiration moved, Yang Tian shouted: "Throw the torch into the surrounding grass, quick!" ”

In the darkness, objects with yellow light were thrown into the grass in front of them, like stars in the sky. Then the dazzling light suddenly burst out, accompanied by a squeaking sound one after another, and the stars spread out with the momentum of a fire away from the original. The grass around the pigs and rats suddenly began to burn violently, and the burning pigs and rats screamed miserably, or rolled on the ground, or desperately rushed towards Yang Tian, but they were nailed to the ground by spears, howling helplessly.

The smell of burnt fur mixed with the smell of roasted rat meat wafted in the smoke, and countless black shadows swayed in the grass in the distance, frantically fleeing from this place of death.

Liu Ye looked at the mess in front of him, and couldn't smile bitterly, it was just a small trial, but they made such a big move.

"Qualified!"

Liu Ye turned around, looked at Yang Tian and them silently, and said, "This is the first lesson I taught you - the importance of tools. Tools are the main marker that distinguishes humans from other lower animals, and humans who do not know how to use tools cannot be considered complete human beings at all. As you have just seen, how much fire has helped you just now, the instrument that has played a vital role in the history of human evolution! I will train you as much as I can for ten days before the thieves come, and although there may be some people who die like today, I promise that those who survive will have great strength, because only such a person is qualified to use this weapon in my hand - the gun - the crystallization of human weapon civilization! ”

Liu Ye didn't know how many people understood what he said just now, but feeling the burning gaze of them staring at the weapon in his hand, Liu Ye felt that his goal had finally been achieved.

Only strong desires can generate great motivation, and only strong motivation can push them to learn powerful skills, which will eventually make powerful warriors!

The fire burned the surrounding grass, but fortunately the grass was located on the edge of the city, and the earth and cement kept the fire within a fixed range.

Unexpectedly, although the fire turned the surrounding area into bare land, it also made the surrounding beasts dare not approach. After all, there were indeed a lot of creatures killed in that fire, and Yang Tian, who originally just wanted to harvest more than twenty pigs and rats, didn't expect that he would get double the income.

At that time, Liu Ye led Yang Tian and them to clean up the scene, collecting the claws, teeth and the like that could be used, and even some of the burnt fur and meat were carefully searched by Yang Tian and them, looking at their cautious appearance, they knew that this kind of thing that was harmful to their health in the eyes of modern people was also a rare food for them.

Therefore, when Liu Ye led these guys to the scene again the next day, there was just an empty space around. Strangely, though, this training session was still held at night.

Liu Ye made a few movements in front of them, and asked a few people to come up and take turns to demonstrate, and the puzzled people realized that Liu Ye was teaching them the most familiar running. Looking at everyone's slightly disdainful gazes, Liu Ye didn't say anything, just asked them to carry the things that were done in a hurry yesterday on their backs.
