I, the Good-For-Nothing Holy Son, Sign in with Billions of Cultivation

The good-for-nothing Saint Son was abandoned in his Dantian, and once he awakened, he awakened to the most powerful sign-in system. Once you sign in, you will be invincible, and you can counterattack and shake the sect, sweep away the geniuses, and crush the enemies. Qinglan is the only one I love in this life. From the Qingyun Sect, I signed up to become the ruler of all heavens!
