Return to Daqin and Become an Assassin

It's a scumbag time travel, no system, not even a golden finger, I don't want to survive more than three episodes, fate plays a trick on me, and I accidentally time travel and become an assassin. It's hard to be an assassin, it's even harder to be an excellent assassin, and it's even harder to be a famous and excellent assassin! Obscene development is my policy, Jing Ke. Voldemort is my method, Jing Ke. Preserving life is the most important thing for me, Jing Ke. As an assassin who will go down in history, being cowardly is the best disguise, being cowardly to the point where humans and animals are harmless, being cowardly to be friends in the world, being cowardly to the point where life is the highest pursuit of all! Thousands of thoughts turned into one sentence, as long as I have my life left, I am not afraid that the assassin will lose his business! I am Jing Ke, I bring salt for myself!
