Yun Chen had thought that Ye Qing was just a teacher with a profound understanding of martial arts at first. But the more interactions he had with the mysterious teacher, the more he was suspicious of his identity.
After all, he looked like he was in his twenties at most and didn't look particularly outstanding but none of the students in the Netherworld Academy could compare to him.
Teacher Ye could even produce an elixir purer than the one the President of the medicine faculty could produce. He could also control the spirit lines and knew so much about the four of them…
There was no way the teacher in front of him was a mere twenty year old.
Martial arts wasn't that difficult to understand but no matter how evil someone was, it wasn't possible to produce such a pure elixir in such a short time.
It wasn't possible even if he had started when he was born!
As for the spirit lines…
