Invincible Faction: Immortal System

I want to die, but I can't. Being activated by such a hateful system makes me feel silently lonely. Fortunately, there is still a happy apprentice who allows me to conduct devil training. Just like that, inexplicably invincible. The novel is written in three persons, not one person. Then I took a bunch of disciples and started a life of burning, killing and looting in the heavens. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
