The Genius with Useless Pulse: Mr. Jing, Please Don't Make Any Noise

On the day when the spirit stone was tested to determine the inferior pulse, Du Han had a mirror in his body. There is an old man in the mirror who claims to be the deacon of the sect three thousand years ago. He has a poor memory, talks a lot of nonsense, and likes to be a teacher. "Your spiritual veins are empty. Empty things can hold a lot." There are nine people in the class with nine useless veins. One month later, in the spiritual academy competition, the last one will be eliminated. Du Han said: "I can't beat him." Mr. Jing said, "I'll try it with you." Nine people, nine useless veins. Mr. Mirror asked: "Can you pretend?" Du Han said: "Try it." Nine people, nine useless veins. What happened later, the old people in Gray Stone Town said, that winter, nine foxtail grasses grew in the cracks between the bricks at the base of the back wall, and all of them bloomed.
