Save the Entire Human Race System

In Leaf Village, year 33, at the Rain Village's mission assignment office.

Inside the Rain Village leader's office, a middle-aged ninja was processing documents, while a young boy stood below.

It had been nearly half a month since the war between the Land of Rain and the Land of Wind began. After Leader Hanzo went to the front lines, all major affairs in the Rain Village were handled by Lord Gray Rain Rui.

Gray Rain Rui, seated at the desk, stopped handling the documents and looked at the young boy in front of him. "Su Zheng, how have your recent training sessions been?" he asked with concern.

The young boy replied stiffly, "Thank you for your concern, Lord Rui. It's going well."

Seeing the boy's expressionless face, Gray Rain Rui coughed a couple of times, changed the subject, took out a document, and handed it to the boy.

"This is your mission this time. You'll be transporting supplies to the front lines with the Akai Squad."

The boy looked through the document. The supplies were just some medicine, compressed food, ninja tools, and so on; nothing special.

Watching the boy review the document, Gray Rain Rui said casually, "Su Zheng, it's been a long time since your mother passed away. When do you plan to return to the family? We uncles, and the clan elders, all miss you and want you back!"

The boy was visibly moved, his hand holding the document tightening before gradually relaxing.

He calmly replied, "Thank you for your favor, Lord Rui. However, ever since my mother left the clan, I've never considered returning."

Gray Rain Rui took a puff of his cigarette and replied, "Well, let's talk about it when you've made up your mind."

"Oh, right. There's a town called Yubu Town on the way to the front lines, and it's not very peaceful. There might be enemy ninjas lurking around, so be careful!"

The boy nodded. As he turned to leave, he saw a faint smile in the swirling smoke.

The boy's name was Gray Rain Masashi, also known as Su Zheng, a transmigrator.

Upon arriving, he inherited the memories of the original Gray Rain Masashi. Gray Rain Masashi's mother was born into the Gray Rain clan, a prominent clan in the Land of Rain. However, she was expelled from the clan for marrying a commoner who was opposed by the clan.

In this cruel ninja world, filled with killing and constant danger, his parents died in a war shortly after marrying his father. He was then raised by his uncle.

It was because of the laughable clan honor, the laughable bloodline, and social status that the Gray Rain clan suppressed his parents, ultimately leading to their deaths. Su Zheng, inheriting the original body, naturally resisted the Gray Rain clan.

Oh, and his uncle was the "Demigod of the Ninja World" – Hanzo of the Salamander!

After leaving the office, Su Zheng went to notify his squad members: Maki Gengetsu and Xiangtai Hongshan.

Su Zheng had excellent grades in the Ninja Academy, so he skipped grades and graduated in the same year as the other two. As a "genius," he was assigned to the same class as his two teammates, with Maki Ci Lang as their guiding Jonin.

However, with the outbreak of war, most Jonin were deployed to the battlefield, so training and guidance naturally ceased. Instead, the squads trained and undertook missions themselves.

During a previous mission, Su Zheng demonstrated his strength, and before Maki-sensei left, he appointed Su Zheng as the captain.

Su Zheng went to the Yakiniku restaurant. The restaurant had delicious food and was quite famous in the Rain Village. Xiangtai and Maki often had dates there.

Su Zheng lifted the curtain and scanned the room. In a window seat on the left, a young boy and girl were happily enjoying their meal, chatting and laughing.

The girl had a black ponytail and a round, very cute face. Her ninja headband was hanging around her neck. The boy had a delicate face and a slightly helpless expression, occasionally placing grilled meat in front of the girl. These two were, of course, Maki and Xiangtai.

Su Zheng walked over and sat down. He looked at Maki and teased, "Maki, if you eat this much, aren't you afraid Xiangtai will dislike you later?"

"He wouldn't dare!" Maki glared fiercely at Xiangtai, making him shiver inwardly.

Xiangtai gave Su Zheng a resentful look. Su Zheng, unfazed, took the relay baton and began to devour the delicious food.

Beside him, Xiangtai was trying his best to prove that he would absolutely not dislike her. Xiangtai and Maki were childhood friends with a very good relationship, but they were lax about training and would go on dates like this when they had no missions.

When there were missions, Su Zheng would find them and always tease Xiangtai. This was a small punishment for not training with him!

After being comforted and receiving several assurances, Maki no longer bothered and continued to tackle the food in front of her.

Xiangtai looked at Su Zheng with a hint of helplessness. "Su Zheng, tell us, what's the mission? Can you stop teasing me next time?"

Su Zheng laughed heartily, put his arm around Xiangtai's shoulders, and replied, "Alright, alright, I won't next time!"

Then, his expression turned serious. "This mission is a bit troublesome. We're going to the front lines with the Akai Squad to transport supplies."

Both of them were a little surprised. Since the war began, the missions they received had decreased significantly. And as Genin, they hadn't undertaken any difficult missions, so it had been relatively safe.

This time was different. They were going to the front lines, and no one knew where danger might come from. Although they wanted to object, they couldn't find the words. This was the meaning of being a ninja. The village protected them, and they had to give everything for the village, even their lives!

After understanding the mission details, both fell silent. Their nice date had been interrupted by such news.

Su Zheng looked at their expressions and reassured them, "Don't worry! We're very strong, and we'll definitely complete the mission safely!"

With things as they were, their date lost its appeal. Su Zheng and the other two discussed many details about what they needed to prepare for tomorrow, and then they parted ways to go home and get ready.

Ever since Su Zheng transmigrated five years ago, he had been preparing, preparing to rewrite the ninja world.

As someone who had watched Naruto no less than three times, Su Zheng knew clearly all the major events that occurred in Naruto at every moment.

The deaths of Scorpion's parents, Nawaki, and Kato Dan during the Second Shinobi War, White Fang's suicide, and even Might Duy's death and Obito's corruption during the Third Shinobi War...

Every time he saw these events, Su Zheng felt despair for this cruel ninja world. Fortunately, he finally had the chance to change it all!

Since his transmigration, Su Zheng, for his plan and also to avoid Hanzo discovering him, had made an excuse: "After entering the Ninja Academy, I need to make friends with classmates and also learn to live independently."

His uncle Hanzo readily agreed and arranged a house for Su Zheng. It was a two-story wooden house, but quite large, over a hundred square meters, with a small yard. Hanzo also visited him from time to time.

In fact, there was a reason for this. Hanzo was also a member of the Gray Rain clan. Because he was treated as a "weapon" when he was young (the salamander's poison sac was placed inside Hanzo), everyone except his mother feared and were wary of Hanzo. Only his mother cared for him, so naturally, she loved Su Zheng out of love for his mother.

It could be said that his uncle treated him very well!

Returning home, he changed into his training clothes and went to the backyard to practice shurikenjutsu as usual.

"Whoosh, whoosh, whoosh!"

On the training post, shuriken were embedded all over it. From a distance of over ten meters, every blade was precisely lodged in the center of the target circle. Su Zheng's shurikenjutsu was quite good, but his biggest problem was a lack of combat experience. Although his teammates often trained together, Su Zheng always dominated them, rarely finding himself in a dangerous situation.

Su Zheng formed hand seals and slammed his palms onto the ground.

Earth Style: Earth Dragon Bullet!

Boom! Boom! Boom! In front of the training post, several sharp, thick rocks bulged out, piercing through it.

Su Zheng formed hand seals, forming the Ox, Monkey, Rabbit, Rat, Boar... a total of 44 seals.

Water Style: Water Dragon Bullet Technique!

The water from the puddle in the small courtyard rapidly gathered, forming a ferocious water dragon.

Su Zheng dispelled the ninjutsu and carefully recalled. He had tested himself before; he possessed five chakra natures.

Although he had Hanzo of the Salamander's backing and could learn any ninjutsu, due to the environment in the Land of Rain, learning Earth Style and Water Style was the most effective and offensive. However, the power of his Earth Style techniques was too weak, and Water Style required too many hand seals.

Sigh, he still had a long way to go!

Shaking his head, he stopped lamenting. Su Zheng formed hand seals, and chakra gathered in his left hand, blue and white chakra beginning to pulse.

Lightning Style: Chidori!

Chirp! It sounded like a thousand birds crying out at once, incredibly piercing. Combined with the pulsing blue chakra, it was terrifying!

Su Zheng accelerated his run, charging towards the training post. His left hand swept through, cleanly slicing the post. The cut was neat.

He still couldn't control the nature and shape transformation of Lightning Style chakra well, which caused his palm to burn. This technique was not perfect and required more practice.

After finishing his practice, he lay on his bed, staring at the ceiling. This was Su Zheng's fifth year after transmigrating. He was now 11 years old, and the ninja world had entered the Second Great Ninja War. Many crucial events were about to unfold: the "Sannin" would become famous, the Leaf's "White Fang" would kill Scorpion's parents, Nawaki and Kato Dan would die, Tsunade and Orochimaru would change, and most importantly—the Rain Hidden Trio: Nagato, Yahiko, and Konan would be taken as disciples by Jiraiya...

Su Zheng looked at the screen in his mind and sighed inwardly. He had a "Save the Entire Human Race System," but it was "unactivated"!

His attempts over the years had made him realize this was a useless system. Not only was it unactivated, but he couldn't communicate with it. It wasn't even "artificial stupidity."

If it could give him even a little power, not much, just the Rinnegan or Sage Body, he could advance his plans.

Thinking of good things, Su Zheng drifted off to sleep.
