In Konoha, I Learned from Kakashi and Became Stronger by Reading Books

Liuyun, who traveled to the world of Naruto, got a somewhat strange system. Just read some special books and you can become stronger! He learned from Kakashi, but he is better than his master. Raikage: "What? I have the strongest armor? This guy Liuyun actually read that kind of book and then killed me!" Sarutobi Hiruzen: "Liu Yun is a freak. I have only seen him reading forbidden books, never practicing, but he can kill me." Uchiha Madara: "? This bastard Liuyun can look like that even when reading a book. What a talent." Uchiha Obito: "Damn! This bastard Liuyun, a person who reads that kind of book every day, is not only not obscene, but can also grow to the point where he can even cut through space!" Liu Yun: "My hobbies are reading and... Killing people." This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
