1 - On This Fateful Day

One day, Xiao Lang is saved by a High Immortal, Wang Zijian, who takes him in as his disciple.

Raised by the wolves, Xiao Lang doesn't understand what it means to act like a human. Running around naked, hunting other Immortals' pets, howling at night... Zijian doesn't have it easy.

Things get complicated when Zijian starts seeing Xiao Lang differently.
