At the beginning, I became a disciple of Tsunade. I can absorb natural spiritual energy.

Along with the Suiren clan, the Chao clan, and the Ziyi clan, the three people taught humans the skills of firelight, houses, and animal skin clothing, which brought great convenience to human survival.

Originally, human lifespan was very short. In addition to those who were killed by ferocious beasts when they went hunting, many humans also brought bacteria from the flesh of ferocious beasts into the human body due to bad weather and eating blood. Caused great harm.

However, because Suiren invented the method of drilling wood to make fire, humans no longer eat the meat of ferocious beasts. The ferocious beasts brought in every day will be roasted by the women of the tribe and the injured and recuperating people. This has greatly increased the number of human beings. Physically, humans in the tribe rarely get sick.

The house construction methods and animal skin clothing manufacturing methods brought to mankind by the Ziyi clan and the Youchao clan also brought great benefits to the human living environment, allowing humans to no longer live in cold and damp caves and giving Humans brought armor to protect them from bad weather.

Moreover, these animal skin clothing and houses can resist the attacks of ferocious beasts to a certain extent, greatly increasing human beings' survivability.

Together with the Suiren clan, the Chao clan and the Ziyi clan are the most powerful humans in the tribe, and they have brought powerful methods and a good living environment to the humans in the tribe. Gradually, the savages in the tribe will Be the leader and lead them to survive in this harsh environment.

Time gradually passed, and in the blink of an eye, fifty years passed.

Because of the contributions of the three Suiren clan, the living environment of human beings has been greatly changed. In addition, human beings practice martial arts and have strong bodies. Therefore, human beings have expanded extremely quickly.

Twenty years ago, humans had spread throughout the entire mountain range, and all the ferocious beasts in this mountain range were eaten by humans. In order to survive, humans, under the leadership of the Suiren clan, the Youchao clan, and the Ziyi clan, began to move towards the mountains. Outside, they were expanding where they had never set foot.

At the beginning, human beings were still a little afraid when facing the unknown environment. However, as the Suiren family showed great strength, even the "evil dragon" hundreds of times larger than them was defeated by the Suiren family. Human beings worshiped the three Suiren clan more and more.

Of course, the so-called evil dragons are just crocodiles from ancient times. However, because this environment was not polluted by anything, these crocodiles became very large, so they were called evil dragons by humans.

However, God seems to be trying to impose a test on mankind. Just when the situation of mankind is in good condition, bad weather suddenly gives all mankind a loud slap in the face.

On this day, the weather suddenly changed. Although humans have not yet experienced seasonal changes during this period, normally, there are four stages every year, and humans have long been familiar with this way of survival.

However, recently, the weather has been constantly changing, from hot to cold, causing many newborn human children to die of illness in large numbers.

Moreover, with the advent of this kind of weather, many ferocious beasts began to become confused. The ferocious beasts that were originally driven away by humans rushed out in large numbers, causing great harm to humans.

The three Suiren clan had no choice but to lead the humans to shrink their territory and build a wall with trees to defend against the impact of the ferocious beasts.

Moreover, the ferocious beasts during this period seemed to have become intelligent. They always attacked human beings' weak defenses in large numbers when humans were not paying attention, causing great harm to humans.

After the Suiren family discussed for a while, the three of them planned to ask the Ziyi family to go to their ancestral land to find Qingyun, hoping that Qingyun would help them survive this crisis.

On the other side, Qingyun has been in seclusion in the wooden house since he accepted the third ancestor of mankind and taught many of his martial arts to the entire human world through the third ancestor.

Although Tsunade and other girls were bored, they stayed by Qingyun's side very sensibly and did not disturb Qingyun with any words.

The most important thing is that before this, they all tried to rush out of the planet by aircraft. However, since they entered the planet, the planet has been bound by an inexplicable rule that prevents anyone from leaving or entering.

Although Qingyun knew all this, he didn't pay too much attention to it. Ever since he taught martial arts to the third ancestor of mankind, Qingyun has been wondering what went wrong, which caused him to delay completing the task.

After all, if he talks about spreading martial arts, he has already taught many techniques, so this task should have been completed.

However, the system has not issued a prompt that the task has been completed, which makes Qingyun very puzzled.

After thinking for a long time, Qingyun felt that maybe he did not leave the martial arts seeds in this place, which caused the delay in completing the task.

You must know that human beings have not been able to evolve from the beginning to later generations. During this period, they have also experienced many disasters that almost wiped out human beings.

For example, this time the weather suddenly changed, Qingyun had already sensed all this. If he had not taken action, the three Suiren clan, whose martial arts had only reached the realm of heaven and man, would never be able to lead mankind through this crisis.

Once the three Suiren clan members die, the martial arts he preaches will collapse instantly. This should be the main reason why his mission has not been completed.

Qingyun has already discovered the reason for this sudden change in the weather. It is all because four children are about to be born. The luck of this world is poured into these four embryos, causing the will of the world to instinctively want to take back its origin. , and this disaster was brought about.

This is also the main reason why Qingyun did not take action even if he saw a large number of human deaths.

Once he takes action to prevent the disaster from coming, after he leaves, this world is likely to undergo great changes again. At that time, if he is not there, the human beings in this world will probably also suffer a devastating blow.

"Ding, release a limited-time mission. Mission option one is to infuse the luck in the ninja world into this world. At the same time, take back the skills of the host who teaches martial arts in the ninja world and infuse it into this world. The mission reward is worth one. million!

Mission option two, let the humans in this world fend for themselves and wait for the birth of the next batch of humans to promote martial arts. The mission reward is worth one million! "

Just when Qingyun sensed Ziyi's arrival and was about to walk out of the wooden house, the system prompt sounded suddenly.

After hearing the system prompt, Qingyun frowned. Although he knew that after he left this world, the skills of Namikaze Minato and other ninjas who had learned their own martial arts would disappear, but he never expected that Namikaze Minato's skills would disappear. Disappear this way.

"System, if I choose option one, will the cultivation of Namikaze Minato and others be completely dissipated or will they be converted in equal amounts in the form of chakra?"

Suddenly, Qingyun seemed to think of something and immediately asked in his mind.

"Ding, the energy in the bodies of those who practice martial arts in the ninja world will be converted into chakra in equal amounts. As for the martial arts, the system will extract their relevant memories!"

The system's cold beep sounded in Qingyun's mind again.
