After waiting for two more days, on this day, Chen Shi beat a pika, skinned it, removed its internal organs, and cleaned it, when he faintly heard the sound of shouting and fighting from the valley.

"Huh?"

Chen Shi put down the pika, hurried away, stood on a high place and looked at the valley, and found that another group of Homo sapiens had come in from outside the valley and were confronting the Homo sapiens here.

Probably, the confrontation is not accurate, it should be said that it is a threat.

This group of Homo sapiens from outside the valley numbered more than three hundred, far more than the Homo sapiens here, and it was obvious that they were very hostile, baring their teeth and shouting at the Homo sapiens here.

Ancient Homo sapiens, including earlier humans, were not so friendly and kind to each other, and when they encountered each other in the mountains and wilderness, they did not invite each other to their homes, but often pulled out stone axes or flints to kill each other directly.

When the food is not sufficient, the corpse of the other party is often eaten.

Obviously, this group of migrated Homo sapiens has taken a fancy to this valley and is loudly threatening the Homo sapiens here, trying to drive them away.

The Great War is imminent!

Especially the migrated Homo sapiens, during the long journey, there are basically few old, weak, sick and disabled, all of them are strong candidates, even if they are females, they are all big shoulders and thick waists, like a tiger's back and a bear's waist, and they are not weak when they look at it.

In such a comparison, the Homo sapiens here can face less than thirty young adults, and the number of comparisons is too great.

And Chen Shi felt that not only the disparity in numbers, but also the disparity in combat strength and morale was also obvious, the long journey did not know how far, now is not such an easy road to walk in the 21st century, hundreds of thousands of years ago, beasts, poisons, miasma, natural disasters abound, and none of the Homo sapiens who can resist these difficulties all the way are weak hands.

So, does this battle still need to be said?

Chen Shi watched silently, the migrated Homo sapiens were threatening the Homo sapiens here, and the Homo sapiens here were demoralized and kept retreating in fear.

It seems that the migrating Homo sapiens don't want to fight anymore, otherwise they will all die, and the best way to scare the Homo sapiens here is to leave.

But the Homo sapiens here are not willing to leave, they are already very difficult to live in this valley, and once they are driven away, there is no way to survive in the harsh environment outside.

It's because the battle will break out in the end.

Suddenly, one of the Homo sapiens who kept retreating suddenly retreated and ran out of his ranks.

"Karma ......"

More than 100 of the migrated Homo sapiens gathered together, and more than 200 people were eyeing each other, and when they saw that one of the "enemies" had "escaped", they couldn't help but shout even more excitedly.

"Yes...... It? ”

It was Homo sapiens A, and Homo A, who Chen Shi was lazy to give the name of the Homo sapiens, rushed towards him.

What does it want to do?

Although these Homo sapiens are less than one meter four tall and have not yet worn shoes, they are extremely fast running, and their endurance is amazing, they have run five or six hundred meters in one breath, and they are not panting much, and when they reach the rock on Chen Shi's side, Homo sapiens A immediately knelt down and prayed under the rock.

No, it's wailing.

It was like an aunt who was not allowed to dance, and the sound startled Chen Shi in a daze, and he almost didn't jump up from the rock.

This guy ...... Are you begging to save them?

Although the words were incomprehensible, Chen Shi could also see what it meant.

Chen Shi frowned, he didn't want to get involved, otherwise he really wanted to be the nanny of Homo sapiens?

"Hey......"

He sighed subconsciously, since he had already intervened before, it was not a matter of giving up now, it was not that he had feelings for this Homo sapiens tribe, but that this Homo sapiens A, since he had been "ignited" by a mysterious person, his intelligence had increased greatly, if he died here, wouldn't it be in vain?

He said that the human beings of the 25th century have interfered with the history of mankind, otherwise the ancestors of mankind would not have evolved into modern human beings...... If this is the case, and let this Homo sapiens A die here, wouldn't it be impossible for humans to evolve into modern humans?

Hey, wait, that's not right!

If he hadn't intervened today, even in the Sawtooth Tiger incident ten days ago, he wouldn't have interfered and watched the Sawtooth Tiger bite the Wise People to death, wouldn't it have been in vain for the mysterious man's interference?

What role does he play here?

It is impossible for the mysterious man to know about his arrival, nor to know that Homo sapiens A will be threatened after he leaves, otherwise he should stay and help Homo A through the crisis.

Is he so sure that Homo sapiens A will be safe and sound?

Chen Shi immediately stood up, looking shocked.

Unless, the mysterious man is indeed sure that Homo sapiens A is safe and sound, but he does not know the existence of Chen Shi, can it be said that this is the will of heaven in the underworld? He happened to be a section of history?

"Just kidding......"

Chen Shi muttered in disbelief, doesn't this mean that before he was born, history had already determined that the important node that opened the transition of Homo sapiens to modern humans was on him?

Damn, then he was almost hit by a taxi when he was a child, and he was really hit and killed by that driver, isn't humanity finished? There are no modern humans?

No, not necessarily, since there is a modern human being, it means that he will never be hit by a taxi and killed......

But if you think about it this way, the reason why human beings in the 25th century will go back to the past and change history is because they got the cube, and if they got the cube, human beings will inevitably die in the future, but if they don't get the cube, and the human beings in the 25th century don't go back to the past and interfere with their ancestors, then modern human beings will not appear......

The more Chen Shi thought about it, the more confused he became, if everything was as he thought, why would he send him back in the future?

Or is it ......

Chen Shi's heart sank, and he had an idea that he was eager to verify.

Without waiting for the reaction of Homo sapiens A at the foot of the rock, Chen Shi jumped up and ran towards the distance like a gust of wind, and the migrating Homo sapiens over there were still deterring, but they didn't want a figure to suddenly fall from the sky and slam into the open space where the two sides were facing each other.

It is estimated that in the minds of the Homo sapiens, except for flying eagles and birds, no other animals have ever been seen to fall from the sky, which immediately frightened the migrating Homo sapiens back several steps.

Immediately afterwards, I saw Chen Shi's appearance again.

Among the many Homo sapiens, the tallest is only one and a half meters tall, and the shorter one is only about one meter and one in height, facing Chen Shi, the tall figure of modern people, it is like facing a giant.

The most terrifying thing is that the gamma suit worn by Chen Shi also distinguished him at once.
