Infernal Demon Dragon: A dog like you dare to face me in combat? Do you wish to die so much?

Xiang Shaoyun is the young master of an influential and powerful sect and is blessed with an extreme latent talent in martial cultivation. From talent comes confidence, and from confidence comes a declaration to give all the so-called geniuses a head start of ten years before catching up to them.

At the bottom of the abyss, when the Old Demon God finally broke the Titan mecha with great effort, a hand stretched out from the fragments and held down its head.

“Congratulations, you have unlocked my limiter.”
