I really don't want to be the Dark Ancestor

[No system + no heroine + invincible at the beginning + villain male protagonist + darkness]

After Ye Feng woke up from sudden death, he found that he had traveled through time.

The good news is that he came to a world of cultivating immortals and became the patriarch of a top clan.

The bad news is that he is the dark source of hatred and fear for all living beings in this world...

(Note: In the early stage, the protagonist's invincible clone descends to the lower world to kill the enemy. In the middle and late stages, he recovers to his original form and kills people in all the heavens and worlds.)
