I've Long Been Tired of Aesthetics from Cultivating Immortals or Something Like That.

Bai Zhan traveled through time and spent his whole life cultivating immortality, which made him tired of it. So, taking advantage of a sunny morning, he successfully committed suicide—— I thought that life would really end from now on, but I never thought that he would be reincarnated again. This time, he was reborn into the same world as before. It's just that in terms of time... It seems that more than 12,000 years have passed.
