In 2206 A.D., the worst world war broke out between the nations, involving almost all the countries.

Weapons of great destruction were misused, and the war began to be out of control, and eventually the entire human race was near extinction, and the earth was also devastated and devastated.

The surviving forces eventually had to face the reality that if they continued to fight, the entire earth would be wiped out, and the bigwigs of several forces sat at the table to reshuffle the cards and jointly signed the "New Yuan Treaty".

The treaty stipulates that the world will be divided into ten regions from one to ten, which will be occupied by the only remaining ten powers, and the ten parties will coexist peacefully, each administering its own region.

At the same time, the consequences and damage caused by this war have also made everyone have a kind of "once bitten by a snake for ten years afraid of the well rope" in the use of high-tech weapons of destruction, the treaty is very clear on high-tech weapons and weapons of destruction, and all high-tech weapons and weapons of destruction are listed in the whole world, and the high-kill weapons manufactured or used by all forces must be strictly controlled, and strict regulations have been made on the corresponding circumstances of the use of each weapon, and the other nine districts will jointly eliminate it.

At the same time, each region has issued corresponding policies for its own region, strictly controlling the firearms and other thermal weapons in its own region, and the manufacture and use of each firearm are strictly controlled by individuals.

The original intention of the new dollar treaty was to reduce the damage caused by weapons of destruction and the serious consequences caused by conflicts between people, and at the same time, the world was in ruins, and neither the population nor the cities could afford to withstand the reduction and destruction.

The New Dollar Treaty aims to forcibly transform the world from a high-tech age to an age of cold weapons. The world has also eliminated the outbreak of war and large-scale casualties for a long time, but there is no suppression and control of high-tech violent machines, coupled with post-disaster reconstruction, people's lives are miserable, which has led to the emergence of various associations and gangs, and the lives of ordinary people are miserable for a while.

In any case, the signing of the "New Yuan Treaty" was a cross-century change after all, and this year was officially renamed the first year of the new century.

S$112, 5th District, Changze City, Changze Airport.

The plane flying from Cagado in Zone 2 to Changze has just landed.

Ye Tian slowly walked out of the airport passage with the crowd, looking at the close crowd of people coming and going, Ye Tian sniffed hard, "The air in the fifth district is not much sweeter than the second district, it's been 18 years, and it's finally back." ”

Whether Ye Tian was born in Changze or not, he himself didn't know. For as long as he can remember, it was his grandfather, an old man scavenging waste, who picked up his infant self on the side of the street, and of course the place that was built of rotten thatch on the corner of the street, barely calling home.

The old man's surname is Ye, when he picked up Ye Tian, Ye Tian had a high fever, the old man had no money to see a doctor, and he asked for medical advice everywhere, no one was willing to help the old and the young, the old man had no choice but to use some physical methods to cool down Ye Tian every day, what he didn't expect was that Ye Tian burned for seven days, and it miraculously got better, in the words of the old man, this child was let him survive by God, so the old man named him Ye Tian.

Until he was 7 years old, grandpa took Ye Tian to ask for food on the street for a living, but he barely survived, although grandpa was sloppy and weak, but he sometimes often told Ye Tian a lot of big truths, so that Ye Tian felt that he was a gentle and elegant person, with great wisdom, and sometimes he would go desperately for Ye Tian and the wild dogs who grabbed food, so that Ye Tian felt that he was a strong man of flesh and blood, in Ye Tian's heart, grandpa was omnipotent, so although the days were very hard, they were also very warm.

Until Ye Tian was 7 years old in the winter, Changze had a once-in-a-century snowstorm, Ye Tian and his grandfather snuggled in the dilapidated grass hut for 5 days, the weather was too cold, Ye Tian's high fever did not go away, plus he did not eat for a few days, his life was in danger at any time, grandpa gritted his teeth, draped the last coat on Ye Tian's body, and touched Ye Tian's head, "Xiaotian, you hold on, grandpa will find you something to eat."

Then the grandfather walked into the snow and never came back. Ye Tian didn't know how long he had been asleep in a daze, and when he opened his eyes, he vaguely saw a man standing in front of him, putting his hand on his forehead, Ye Tian was in a coma and vaguely heard a sentence, "A guy like you who is like a wild dog may be more suitable to survive in the Shura Field." ”

Ye Tian woke up in Changze Hospital three days later, and the man who rescued him told him that it was an old man who froze to death and begged him to take care of Ye Tian.

"My name is Shura, and you can call me Master in the future. Your grandfather and I paid for the burial, but I am not a great good person, nor am I the one who came to save you, everything you get in this world has to pay a price, what you need to pay is yourself, don't ask anything, follow me. But before leaving, you can go to see your grandfather for the last time, because the next time you come back, you don't know when it will be, and you may not even be able to come back. ”

The man said lightly, without a trace of emotion in his voice.

Ye Tian looked at him, was silent for a moment, turned over and got out of bed, knelt on the ground, and kowtowed three times.

"Anyway, it was you who saved my life, it was you who paid for my grandfather's burial, such a great favor, I can't repay it, after I say goodbye to my grandfather, everything will be arranged by you."

The man glanced at Ye Tian with a little surprise, but he didn't say anything.

Ye Tian cried for the last tear in front of his grandfather's tomb, and then followed the man to the second district, the name Shura is in the second district, and he is the founder of the Shura team, the first killer organization in the second district, which everyone knows. His master, the man named Shura, kept going back and forth between the ten regions, and collected more than 100 children like him, who were homeless and would not be cared for when they died, and brought them to the Shura field, the base camp of the Shura team, for training and training, and fought and eliminated among these children, and after ten years of hellish cruel training and cultivation, in the end, less than 10 of the more than 100 children survived and officially became members of the new generation of the Shura team.

And Ye Tian is precisely the most outstanding member of this, and he is also the successor of Master Shura's key training, when Ye Tian was 25 years old, the master died of illness and handed over the Shura team to Ye Tian, and Ye Tian was also tired of the life of a killer, so he handed over the Shura team to his brother Gao Junxi, and embarked on a journey back to the fifth district.
