Naruto: Sasuke Has a Cloning Lab

[Naruto] [No Heroine] [Leveling Up] Blurb One: Zuo Zhu died suddenly after staying up all night, then was reborn as Sasuke Uchiha in the world of Naruto. With an identity like that, even if he knew nothing and simply followed the original story, he was practically guaranteed to become one of the strongest people in the shinobi world! What, he even has a golden finger? A laboratory that can endlessly clone almost any living thing? There are so many possibilities! If he works hard, becoming the true Otsutsuki Sasuke isn't just a dream! But first, he has to get an invitation from Snake Guy, the man who controls the “core technology.” (This isn't a pure wish-fulfillment story.) Blurb Two: The Uchiha Clan are descendants of Indra, the eldest son of the Sage of Six Paths, and a clan steeped in tragedy. Emotions brought them strength, but too much of anything can be harmful. Overwhelming emotions often become the root of tragedy, hurting both others and oneself. Perhaps, for someone born into this clan, the best way to break its curse is to be completely rational and never let one's emotions take control. Zuo Zhu was reborn as Sasuke in the world of Naruto, but he is only an ordinary person. He has his own feelings and can be influenced by the world around him. Personality determines fate. With the destiny Sasuke was born to bear, combined with his personality, perhaps, as the last Uchiha, with his deeply sensitive heart, he is doomed to be a complete and utter tragedy. But extremes can reverse, and fortune may follow despair. If his emotions are even more intense than those of an ordinary Uchiha, perhaps he can still find his own path through distortion and obsession. (The protagonist pursues power and seems hypocritical and cold, but beneath the surface he is deeply emotional, sincere, and passionate. If that's not your thing, don't read.)
