Nine Yins and Nine Yangs in Naruto

On the ninth day of overtime work, I choked to death on a cigarette. Traveling to Uzumaki Village, the whole village tested me: Chakra, zero. It doesn't matter, I have a system of martial arts cultivation in my mind, and I will give you the Nine Yang Magic Skill at the beginning. While others practice chakra, I practice internal strength; while others take the chunin exam, I meditate in the system space. Got caught practicing boxing every day? Oh, the taijutsu ninja knows everything. Later, they asked me what state I was in. I thought for a while: probably... It is a state that cannot be retained in this world. Change the plot, dig holes, and make it a semi-daily novel.
