Cultivate in Womb, Sweep Nine Heavens

Jiang Xiaoyao transmigrates as a fetus and awakens a system that rewards him tenfold for helping his mother cultivate, strengthen her bloodline, and enhance her enlightenment. Facing discrimination within the Jiang family, Jiang Xiaoyao uses the system to rapidly improve his mother, leading to blessings from a Sage, the awakening of his bloodline, and the ascension of the Sword Tomb. He slaps the face of the villains, even capturing the Saintess with his spiritual分身 while still in the womb. By the time he is born, he is invincible, kicking his Sage grandfather away and effortlessly defeating the Demon Ancestor of the Upper Realm.
