Sima was born with a Chaos Body, but a rootless heavenly thunderbolt sealed it, leaving him a cripple. Ten years later, divine thunder struck again and awakened his Chaos Body. He then learned that he could cultivate without a dantian, and that the stronger the tribulation he survived, the greater the power he gained. From then on, he embarked on a path that used tribulations as steps, blasting through the barriers between the myriad heavens and realms to reach the supreme peak.
