I can make mistakes countless times, but you only get one!” After resetting causality hundreds and thousands of times, Qin Yang finally forges the strongest timeline for himself.

With a flick of his fingers, heaven and earth collapse, gods perish, and immortals are destroyed! “Wait, how did this guy become invincible the moment he was born?”
