In the Second Generation of the Trench, He Changed To the Ruanfan Script - Chapter 16:

In the spirit of love and in order to help his ex-boyfriends walk out from the shadow of heartbreak, every time before Ye Ming leaves after successfully completing each world’s romance mission, he will ‘kindly’ (ruthlessly) break up with with his boyfriend.

After transmigrating to N different worlds he had finally gained enough experience. At this time the system informed him that because the accumulation of his ex-boyfriend’s grievances had exceeded critical levels, leading to the failure of all his missions…. So he needs to return to each world to eliminate their grievances if he wants to complete his missions!

Ye Ming: This is an outcome I didn’t predict.

System: I tried to tell you before that if you did this you won’t have a good end.

The ex-boyfriends all laughing coldly: He He. That despicable scum that ran away after deceiving my feelings is finally back. This time don’t even think about running away!

Ye Ming: ……

System: Since you “zuo” yourself to death, even if you kneel you have to go to the end!

Ye Ming: Luckily I have a special “scum cleaning” technique ^_^
