[Two Male Leads + System + Happy Ending + Transmigration + Taming an Emperor + Historical Fiction]

The Host of System 2778 was once a die-hard fan of Ying Zheng. But after defending Ying Zheng's merits and faults, he was maliciously doxxed and cyberbullied, eventually dying by suicide after falling into depression.

System 2778 was forcibly dragged into possessing a body. After accidentally getting himself killed, he transmigrated into the famous assassin Jing Ke.

Now that the Host of System 2778 is Ying Zheng's number-one fan, he has to assassinate Ying Zheng, the First Emperor. Is this a doomed start from the very beginning?

It should have nothing to do with System 2778, but after residing in the Host's body for so long, he has inevitably been affected by the Host's will from before his death.

Ying Zheng is focused on building his empire. How could he tolerate a lowly assassin challenging his authority?

But this assassin is just too interesting.

So Ying Zheng decides to hold back for the time being.

System 2778 is on edge every day, afraid of vanishing without warning. After all, the butterfly effect is terrifying and irreversible.

He fears history will be changed beyond recognition.

But why is something not quite right about the Ying Zheng here?
