Unexpectedly, a disciple I accepted by chance mistakenly thought that I was a peerless master. In order to keep this good disciple, I pretended to be a master every day. "Master, I'm seventeen years old. Is it normal that I haven't opened my Sharingan yet?" "Master, why didn't I gain any abilities after eating the Zhenzhen Fruit?" "Master, I used the Zanpakutō you gave me, but why can't I use Getsuga Tenshō?" Whenever my disciple asked, I thought the lie would eventually be unsustainable, until I saw the 100-meter-tall Susanoo, and I was so shocked! … My name is Ning Hai. I am in my third year of high school and the college entrance examination is about to take place. I am under a lot of pressure. Fortunately, I have succeeded in becoming a master. Under the careful guidance of my master, my original talent was mediocre, but my strength improved rapidly.
