Zhao Qingyun, the youngest ninth-grade alchemy master of Tianxuan Sect, appears to be a gentle alchemy genius, but in fact he is an old fox with a dark belly. His greatest pleasure is not refining elixirs, but digging holes for those who have evil intentions against him.
Until that day, he took on an apprentice.
Lin Xiaodie, a stupid thief who claimed to be "lost", sneaked into Tianxuan Sect to steal the elixir but failed, but was caught on the spot by Zhao Qingyun. When everyone thought that this stupid thief would be executed, Zhao Qingyun accepted her as his disciple with a smile.
"Master, how do you light a fire in this alchemy furnace?"
"Think about it with your stupid brain."
"Master, I was bullied!"
"Oh? Then I will teach you something more ruthless."
"Master, did you already know that I came to steal things?"
"I know, but you are too stupid. I can't bear to see you get caught."
One is a master who seems serious but is actually sinister, and the other is a stupid apprentice who seems innocent but is actually shrewd. On the surface, the two are masters and apprentices, but secretly they plot and frame each other.
However, when the crisis came, this relationship of love and killing became their strongest bond.
