I’ve been invincible since Dragon Ball

Traveling through Dragon Ball, Gu Xuan was surprised by the system. It starts with 100 billion combat power at the beginning, and can evolve infinitely.
From then on, all the heavens were invincible.
Sun Wukong: I used to always like to find people to fight, until I met Gu Xuan…
Thanos: I don’t like people touching my head, but I can’t beat Gu Xuan.
Bruce Wayne: I would rather have a hundred clowns in Gotham than see Gu Xian again.
