Forgotten Title An mc in cultivation who can't die or revives everytime.

I remember a scene where the mc tricks someone else, he puts a bomb in his mouth, he prays for immortality something and stabs himself to death. Then he acts like he revived. Puts the bomb down and leaves. The guy who saw him from the sideline takes the bomb in his mouth and prays, then the mc blows up the bomb and kills the stronger cultivator guy with this trick.

 

title name it's lonely to be invincible
