I Am the Holy Lord, One-Eighth of the World's Darkness

The protagonist, Li Yang, transmigrates into Jackie Chan Adventures and becomes Shendu, inheriting one-eighth of the world’s darkness as a concept. He wields the power of the twelve talismans and dark magic, and can summon the Shadowkhan. When he transmigrated between worlds, he also absorbed the aura of the multiverse, allowing him to answer the call of darkness from different worlds and divide off parts of himself to enter them.
