Sharingan?

"Hmm? Why is my head so dizzy? Where am I?" After Zheng Yuheng woke up, he shook his head, trying to dispel the groggy sensation. But things went against his wishes. It would have been fine if he had not shaken it, but the moment he did, he collapsed again. After losing consciousness once more, he seemed to have a dream. In it, his name was Uchiha Sasuke. He had been born into the Uchiha Clan. His father was the Clan Head, his mother handled the housework, and he had a genius older Brother. He was always pestering his Brother to train with him, hoping he would teach him how to throw Kunai.

That happy life came to an end. For some unknown reason, his Brother had slaughtered the entire clan by himself. When he finally faced Sasuke, his eyes were full of disdain. Then he attacked with Genjutsu. It seemed that the last two words his Brother spoke were, "Tsukuyomi."

Is this Naruto? Why would I dream about scenes from Naruto? Wasn't I supposed to be dead?

Zheng Yuheng had just graduated from university, and he had always kept up with the Naruto anime. He had finally made it to the ending, but honestly, although Japanese anime was good, it dragged on far too much. If you followed several long-running series at once, your whole life would probably pass by. Especially once you got older, you absolutely should not keep watching them. Otherwise, you might die before the anime was even finished.

After graduating, Zheng Yuheng found a pretty good job as an accountant at a restaurant. That was right—he had studied accounting. His family ran a barbecue restaurant, and ever since high school, he had helped out with the accounts every day after class, honing impressive mental arithmetic skills. So he had simply chosen to study accounting. After graduation, he wanted to stay in a big city. After all, his hometown could only be considered a second-tier city. So he had come to this restaurant to learn, working while observing how restaurants in major cities were run, which would make it easier for him to start his own business in the future.

That was where the tragedy happened. Having just arrived at the restaurant, Zheng Yuheng wanted to show initiative, so he worked overtime there on his very first day, determined to sort out the restaurant's accounts as quickly as possible. Unexpectedly, he encountered a thief that night. While doing the accounts in the office, Zheng Yuheng heard noises downstairs and ran down to take a look. To his surprise, the other person came right at him and stabbed him more than a dozen times. It hurt like hell. But the pain came quickly and went quickly, because he died. Even now, he had no idea what that person looked like, what he had come to the restaurant for, or why he had stabbed him several times on sight. Carrying a pile of unanswered questions, Zheng Yuheng had left this world. Fortunately, he still had a younger brother. Their family was in business, so they did not care about the fines for violating family planning policies.

When he woke up again, Zheng Yuheng examined his surroundings once more. This was a hospital room, and a private one at that. To the left of the bed was a white cloth screen that seemed to block the door. To the right stood a small bedside cabinet. Zheng Yuheng got out of bed and saw a mirror on the wall. He walked over, intending to see what he looked like now, but he could not see himself at all—because his body had become smaller. This time, when he woke up, he was completely lucid. He could feel that his body had shrunk, and there was no pain anywhere. He did not feel like someone who had been stabbed more than a dozen times.

The mirror was a little too high. Zheng Yuheng looked around and found a small stool beneath the hospital bed. He pulled it out and placed it under the mirror, then climbed onto it. At last, he could see his reflection, but the moment he did, he froze. He was far too familiar with the person in the mirror. It was someone he had often mocked before—Uchiha Sasuke. The young version of Uchiha Sasuke, with black hair, big eyes, and an expression not of coldness, but shock. At the same time, a pair of One-Tomoe Sharingan gleamed in his eyes.

That's not right. Why had my Sharingan awakened? It hadn't awakened at this point in the anime. Why was this happening? After his initial shock, Zheng Yuheng calmed down. That was thanks to the countless transmigration novels he had read. Who did not want to transmigrate? After reading those novels, everyone dreamed of transmigrating, and he had too—especially into his favorite, Naruto. He had even made preparations for it.

What had he prepared? Martial arts. Zheng Yuheng had gone to learn Tai Chi as a substitute for Gentle Fist, and he had also learned Xing Yi, because Xing Yi could imitate twelve different animals and was very interesting. With interest, he naturally learned well. But he had only just begun to get the hang of it before that sudden attack sent him here. If he had trained for a few more years, he would not have been stabbed more than a dozen times.

There was no point dwelling on the past. The situation now was extremely serious. What was he supposed to do? He had always mocked Sasuke for being such an idiot. Now that he had become him, what was he supposed to do? And why had his Sharingan awakened?

Zheng Yuheng closed his eyes again and used the memories he had fused with Sasuke's to shut off the Sharingan, which meant cutting off its supply of Chakra. Sure enough, it worked. When he opened his eyes again, the Sharingan had disappeared. Zheng Yuheng jumped down from the little wooden stool, put it back where it belonged, then lay back down on the bed and pulled the blanket over himself, making it impossible for anyone to tell that he had gotten out of bed.

Lying there, he began to think. There had once been many Naruto discussion forums where people studied how the Sharingan awakened, the drawbacks of the Mangekyō Sharingan, and how to obtain the Eternal Mangekyo Sharingan. Zheng Yuheng had taken part in those discussions as well. Combining many other people's ideas, he had formed a theory of his own.

Besides requiring a bloodline limit, the Sharingan also needed Chakra to provide it with energy. So where did Chakra come from? It was the product of physical energy and spiritual power combined. The two needed to be balanced, or rather, only someone strong in both could possess powerful Chakra. Awakening the Sharingan required tremendous spiritual power. That was why so many members of the Uchiha Clan found it difficult to awaken their eyes, and why they were more likely to awaken them after receiving external stimulation, such as a life-or-death crisis. Immense mental pressure forced the mind into an extreme state of concentration, reaching a peak and instantly meeting the conditions for awakening the Sharingan. But that was not the best method.

As for saying that the Uchiha Clan was a cursed clan, that was nothing but self-pity. They simply had not found the proper way to awaken the Sharingan. Or perhaps they had been a lofty clan from the very beginning. Those clan members whose eyes had awakened possessed great combat strength, and later generations had lost themselves in that glory. They had forgotten the creed of ninjas and stopped studying and training diligently, stopped tempering their willpower—that was, their spiritual power. Only powerful willpower could continually drive a person to improve and grow stronger.

Those were Zheng Yuheng's thoughts. He believed that his arrival had strengthened the spiritual power of Sasuke's body, meeting the standard for awakening the Sharingan. That was why the Sharingan had activated on its own.
