In the Second Generation of the Trench, He Changed To the Ruanfan Script - Chapter 35:

Tong, a sinner who was suffering endless torment in hell because of his mistake he had done in his previous life, was giving other chance to redeem himself by the devil.

Wan Tong was bound by the “Corpse Collecting System” and travelled through various small worlds. Her mission is to use the big boss’ white moonlight’s body to resurrect and stop raiders from looting the big boss’ luck.

Wan Tong : Didn’t you say that the big boss has no emotional line?

System : Who brought the white moonlight back to life →_→

Wan Tong : …. sob, sob, every day I try my best to help the boss deal with the raiders, but the boss is thinking about how to attack her!

PS :
(1) The male lead is the same person, the white moonlight is the original MC, which is mentioned later.
(2) Every world is probably sweet love

T/N : white moonlight = first love
