I'm a dead house summoner in the last days

I, Li Tiansuo, friend of the four peddlers, successor of the emperor, number one villain in Tevat, Dr. Babel... ([-] words omitted here), somehow returned to a month before the end of the world when I was on the verge of death.
In my last life, I tried my best just to live a normal and happy life. This life has been reset, but what should I do if I just want to lie flat?That being the case, solve all the problems so as not to be counted again. (Tzeentch:?)
