Sakura's school days were very easy for her. She read books very quickly, so she had already mastered all the theoretical knowledge. It took her a year to memorize all the books in the public library of Kiba Village.

She needed a lot of data to support her upgrade. As a former artificial intelligence, she only felt safe when she had a lot of information, and her ability to grow depended on the amount of data.

However, this world was too primitive. If there was a Skynet or even the Internet, the speed at which she absorbed data would be many times faster. But now, this world only had electricity and no Internet. She could only use her eyes to collect data, which was an extremely inefficient way.

After a year of crazy reading, Sakura, who had not graduated from the ninja school, had mastered the theoretical knowledge. In fact, she had already surpassed the level of many Jonin. If it weren't for the limited number of books in the Kiba Village library, she would probably be the most knowledgeable person in the world.

However, there were too many books about ninjutsu, medicine, and so on that were not suitable for everyone to read. Not everyone in Kiba Village could have Chakra. In order to prevent people from blindly learning ninjutsu and causing harm to their bodies, there were almost no books related to ninjutsu in the library.

In addition to collecting data, Sakura also spent a lot of time thinking. Although she always felt that there were some differences between herself and a real human, she had to admit that the ability to think and create was unique to humans. Now, she was no longer the machine that was programmed to only calculate. She liked the feeling of thinking.

She spent most of her time in class thinking, which made her look more like she was in a daze. However, her grades were very good, so the little turnips in the ninja school gave her the nickname of Bookworm.

Even though Sakura could beat them in the practical exam, this malicious nickname followed Sakura throughout her school days.

Sakura didn't care about the nickname. After all, she often gave others nicknames. She knew that it was very impolite, but why did she want to be a good person?

She was no longer a machine. She had to have her own personality.

After all, imperfection was the characteristic of human beings.

However, Naruto had a lot of fights with the group of children who regretted not being able to graduate because of Sakura's nickname.

"Actually, it doesn't matter. All of us have nicknames. For example, you are called Vixen, and I am called Bookworm."

Sakura smoothed the angry Naruto. Sakura, as his only friend since childhood, naturally received all of his protection. Although Sakura was persuading him, she was actually very happy. "I also give others nicknames, such as Uchiha guy that you hate."

Sakura sometimes found it funny. She and Naruto were the same. If she was provoked by others, she wouldn't care, but if the other party was ridiculed, she would be angrier......

Was this the friendship between humans?

"You mean Sasuke Uchiha?" Naruto's eyes widened. "I thought everyone liked him very much, hahahaha!!"

Sakura didn't circle around Sasuke like the other girls. She was really happy.

"You don't have to think that he's more handsome than others. Look at his eyes and hair, they're all black. Even his clothes are dark. If we were drawing him in a comic, he'd only need a pencil to draw him, but we need to color him."

Sakura liked Naruto's golden hair very much. It made people feel energetic.

"Color?" Naruto understood. "Pfft, hahahahaha. That guy is black and white, right?"

"Yes, so our completion rate is higher. The one in Uchiha's family can only be called a sketch."

The nickname Uchiha's sketch had been used by Sakura and Naruto for a long time, until the Uchiha family's incident.

That night, other than the Uchiha family's gathering place, other places were not disturbed, especially the Haruno family who lived by the river. They were surprisingly far away from the incident.

However, Sakura was still awakened by the malicious and bloody smell in the air in the middle of the night. She hadn't seen many people from the Uchiha family, so she couldn't tell who the owner of the bloody smell was. The next day, Sasuke Uchiha didn't come to school. A few days later, Sakura learned about the Uchiha family's annihilation from Bubuki's mother.

Sasuke Uchiha became an orphan. Naruto told Sakura that he was so pitiful now. They shouldn't call him by his nickname anymore.

Sakura nodded.

When Sasuke returned to school again, his aura had changed. The heaviness and sadness on Sasuke's body made Naruto, who wanted to comfort him, shrink back. Fortunately, Sasuke was very popular in school, and many people wanted to comfort him. Naruto, who had always been at odds with Sasuke, could comfort him.

"Even if you comfort him more than others, the two of you can't understand each other." Sakura smoothed Naruto's hair.

"But we're both orphans …" Naruto was affected by the sadness of others. He had always been very sensitive to other people's emotions.

"That's not the same. You never had a family, but Uchiha had had and lost. The murderer was still his family. The two feelings are completely different."

Sakura silently sighed that Naruto was really a simple and kind silly child. He was already unlucky enough, but he still wanted to comfort others.

"So Sasuke Uchiha is more pitiful than me now?" Naruto blinked.

"I don't know, but I think the two of you are equally matched. After all, Naruto, what if your parents loved you very much before you left?"

"Yiya —!" After imagining it, Naruto suddenly shouted, "I don't want to!"

Just like now, Naruto already felt that his life was very happy. If he was lucky enough to have a happy family and then lost them overnight, he would definitely not be able to bear it.

"That's why no one can understand each other."

Just like Sakura, who lived in a happy family, who would understand the confusion and uneasiness in her heart? She couldn't even be as sad as Uchiha. After all, everyone thought that she should be happy. She couldn't find a reasonable excuse for her complicated and strange emotions. She couldn't even find a reasonable excuse for her complicated and strange emotions.

There was no empathy in the world.

The feeling of helplessness while watching others suffer misfortune made Naruto lie down on the table like a cabbage without water. However, time still passed in an orderly manner. Some scars would fade with time, but more scars would be buried in the depths of the heart and gradually rot until one day they would break out again.

As graduation approached, Naruto fell into a panic.

However, he should be panicking. He didn't pass any of his subjects.

For so many years, it was a miracle that he wasn't expelled by the school. Graduation was basically an extravagant hope for him.

"Naruto Uzumaki is obviously good friends with Sakura Haruno, one of the best children in this class. I also saw Sakura Haruno tutoring him. Why is his grades still so bad?" The ninja school teacher, Iruca sighed helplessly.

However, if someone knew how Sakura tutored Naruto every day, the ninja school teachers would find that Naruto's poor grades were not his fault alone.

After all, he had a pig teammate who was a strong hindrance.

"First make the hand seals, then understand your own elemental composition, find these elements from the air, and start building them around yourself from the bones, then fill in the internal organs, blood vessels, and muscles, and finally skin and hair, so that a complete Body Clone Jutsu is completed."

Sakura, who had a 90% accuracy rate, was helping Naruto learn the Body Clone Jutsu. In her opinion, this Ninjutsu was almost compulsory.

"Sakura … Speak slowly!" Naruto made the hand seals with a blank face. "What are elements?"

"Elements are hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, ne-"

"Slow down QAQ!!!" Naruto was about to cry.

Therefore, the effect of such tutoring was like a sow climbing a tree.

Speaking of Sakura's Ninjutsu method, the teachers didn't realize that in fact, Sakura's Body Clone Jutsu had a physical body, just like the high-level Shadow Clone Jutsu recorded in Kiba village. Because Sakura understood the Ninjutsu taught in each school, her different brain circuit always had some deviation. Instead of saying that she learned these Ninjutsu, it was better to say that she created a new Ninjutsu that looked exactly the same every time.

And the foundation of her use of these self-created Ninjutsu was her Kekkei Genkai limit. She could understand the world at a microscopic level, so she had the ability to create and destroy.

But the activation and control of these abilities all needed Chakra to drive. The Haruno family's inherited physique didn't have a large reserve of Chakra, which greatly limited Sakura's ability.

It was equivalent to her moves were very powerful, but the time she could use them was too short.

"Although I'm a girl, it's still a big problem that I can't last for long …" Sakura was also very worried about this matter. Fortunately, her ability was invincible at the level of her age. After all, her reaction ability and thinking speed were unmatched by humans.

Once again, under Sakura's teaching, he felt that his IQ might not exist. Naruto went home with a depressed heart. The next day, he failed the exam.

Sakura originally wanted to comfort him with a few words. At worst, he could study again for another year. Maybe there was a problem with the teachers in their class, right?

Kaio Iruca inexplicably sneezed.

But after being declared unqualified, Naruto ran out, who knows if there were still tears on his face.

Sakura actually didn't care about the identity of a ninja. She originally thought that if Naruto really couldn't graduate, she could also not be an old ninja. It would be good to cooperate with them to open a noodle shop.
