Good news: I have traveled through time.

Bad news: I have traveled through time to the world of the Lord of Mysteries.

Good news: I am familiar with the plot related to mysteries, although not all of them.

Bad news: I seem to be the backup of Tianzun, and I have a fundamental conflict with the protagonist. It's either you die or I live.

But these are not important. The important thing is that I was forced to drink the "Assassin" potion just after I traveled through time.

Two bottles!!!

(This book only involves and uses the settings in "Lord of Mysteries", and will not involve "Fate Ring")
