MTL - Heavenly Calamity - Chapter 13 Underwater treasure chest

Shen Zhixian transmigrated into a book as a cannon fodder master who hatefully severed his disciple’s spirit root. This disciple fell into the devil’s path and returned to make mincemeat out of him.

Shen Zhixian: …Disturbed.

Afterward, he realized one truth: Being a master is a high-risk occupation. Not trivial at all!
