Infinite Reincarnation Begins with Jing Ke's Assassination of Qin

I randomly picked up a piece of broken jade, but was forced to be bound to a cheating system of infinite time travel - oh no, it was infinite reincarnation. The beginning is the death scene of Jing Ke's assassination of Qin. His teammate is a cold-blooded player who can only say "um" and "oh". I tried my best to assassinate N times, and finally succeeded! Come back and read the history books - Jing Ke failed to assassinate Qin. What are you doing? How many shady things are hidden in this history book?
