Genius and the Old Man Holding His Thigh

In this world, secret books will fall from the sky. If you are lucky, you may even find an ancient master who lives in a book and can teach you how to practice step by step. Everyone calls this kind of adventure - "Grandpa". Lin Xiaofan picked one up. "Grandpa" calls himself Ye Tong. He became an immortal at the age of thirty, has unparalleled martial arts skills, and has a very bad temper - he insists on being called "Brother Ye". Lin Xiaofan believed it. He called Brother Ye respectfully. What he doesn't know is—— Ye Tong is not an immortal at all. He is a remnant soul that was chopped to death with a sword. He is full of tricks. He has only learned one thing since he came back to life: he can't trust anyone. He lives in this silly boy's head, and his idea is very simple - teach him the skills, make him a handy knife, and avenge himself. The plan was perfect. The only problem is: this "knife" treats the person who sharpens it as a brother. After being stabbed, it lay in a pool of blood and said to him—— "Isn't this also you, Brother Ye?" Ye Tong's plan has not changed. What has changed is himself.
