Even heard Devil King Jin published a math tutoring book, and specially asked Lin Yun to buy several copies for him.
He thought Devil King Jin was super cool and handsome,, not only great at Go but also a math genius,, and above all, a super beautiful sister (even with a mask on), so Jiubo had quietly started to worship her in his heart.
"Rong Zheng brother, look,, Devil King Jin is super amazing. I want to learn from her."
Jiubou opened the video and handed it to Rong Zheng to watch. Rong Zheng's eyes lit up as well; he had gone to the site to find Zhen Muqing at the time, but the Go battle had already ended.
So he hadn't seen the whole process, only heard that a girl named Devil King Jin or Mu Zhijin cracked it.
Now having the chance to see this video, Rong Zheng felt inexplicably excited.
He even always felt that girl... had a strong sense of familiarity.
Too bad he couldn't see her face clearly with the mask on.
