Uchiha in Demon Slayer

[Non-travel + no system + Sharingan + special identity Son of Yang + genius boy] Shocked! I didn't expect that in the world of Demon Slayer, there would actually be an Uchiha clan! As the eldest son of the Uchiha clan leader, Seitake is an invincible genius. Unexpectedly, he is actually the son of Yang who only meets once in a thousand years. He has the strongest Sharingan. What will happen to him? Note: This book is a mix of comics and fan fiction (Naruto + Demon Slayer), without a system! ! ! The main world is mainly Demon Slayer. As for the characters of Naruto, they will not be involved. They will just borrow the setting and skills of Sharingan and some classic scenes. The main characters are all original. The protagonist and supporting characters are brothers, both locals, not time travel! ! ! The heroine Ninja, in order to promote the development of the plot, some of the original content may be modified. If it is not detailed in the comics, the author will make his own guesses. Please don't criticize! In order to evolve the Sharingan of Male 1 and Male 2, the author may slightly modify the character, I hope you can be tolerant! Thank you all! (The author plans to serialize this book for a long time and does not plan to write an ending. If the story of this generation is finished, I will continue to tell the story of the next generation, just like Boruto. After the story of Qingzhu is completed, I will tell the story of Qingzhu's son. The story of Qingzhu's son is completed. I will tell the story of Qingzhu's grandson, and so on. I hope everyone is interested in reading it. Thank you again!)
