Heavenly Thunder in My Body: Supreme Mage

Mu Zhixuan was born amid extraordinary celestial phenomena, yet he was a useless waste who could not cultivate. Fourteen years of being branded a failure came to an end when a bolt of heavenly lightning struck him. The lightning entered his body, awakening his Innate Chaos Constitution. From then on, he could summon wind and rain, and reign supreme. On a sudden whim, he became one of the youngest elders of the Immortal Dao Alliance. Then he unexpectedly discovered that humans could cultivate the techniques of the demon race, too. In search of the supreme cultivation art, he set out on a long and arduous journey.

The cultivation levels are: Qi Refining, Foundation Building, Core Formation, Nascent Soul, Out-of-Body, Spirit Separation, Body Integration, Great Vehicle, and Tribulation Transcendence. Each level has three stages: early, middle, and late.
