The Complete System of All Heavens

What, I traveled through time again, and the system rules I got this time were... I actually found Uncle Liu next door, and asked him to punch him ten times. The reward for the task was...

Respecting the elderly and loving the young is a traditional virtue, damn it... Could it be that this time I have to lose my moral integrity and prepare to fight?
