Big brother who just wants to live

I came to another world to live again. It looks like a relegated immortal with excellent talent. I was accepted by the sect and became a big senior brother. I should have been a winner in life. But on the day when I just arrived at the soul refining period, the system came out. She also told me that I was actually a villain. If I didn't choose according to the options she gave, I would be stabbed to death by a group of protagonists with swords in a few years!
