Eternal Existence, My Dog Is Invincible

Xiao Fan transmigrates into a cultivation world and awakens the Eternal Existence System, sharing immortality with a black farm dog named Black Emperor. While others cultivate to ascend, he cultivates to avoid death—starting at Qi Refining stage, he bides his time until invincible. 'A gentleman takes revenge, even if it takes a thousand years.' Xiao Fan holds a 'Book of Enemies,' waiting for his opponents to die of old age so he can sweep their graves; Black Emperor awakens the power to devour the heavens but only cares about gnawing spirit stones. When his sect is destroyed, he digs a hole and sleeps; when spiritual energy dries up, he sleeps for a thousand years; when myriad races war, he seizes the chance to loot corpses. After the ten prodigies' graves have grown grass several times over, after an immortal emperor falls and the heavenly dao shatters, that farming Qi Refining 'weakling' is still there, and that thieving black dog is still there. 'I am not invincible,' Xiao Fan says, patting Black Emperor's head, 'I just live long enough for all my enemies to become history.'
