I Just Want to Do Business and Cultivate Immortality at the Same Time

I just want to quietly use the system to cultivate immortality and do business, but I have no choice. I was forced to carry a mission as soon as I started. The key is that I don't know what the mission is. The most important thing is that someone is pointing a butcher's knife at me. What should I do? Wait online. It's quite urgent... (Ps1: The protagonist is very funny, semi-invincible. PS2: The author is in school, updates 1 to 3 times a week, updates are unstable, and he is not a eunuch anyway, even if you wait until the end to watch...)
