Becoming the Zombie King in a Tomb-Raiding World, Bound to a System

Su Shi was an ordinary person on Earth until one day he suddenly transmigrated into a crossover tomb-raiding world and became a child of four or five. This child’s body was actually that of a zombie king from another world, and he was adopted by a married couple. His parents died when he was thirteen, leaving him an inheritance. Then, one day when he was fourteen, he inexplicably bonded with a System. The rewards this zombie king receives are completely out of character: the bloodline of a five-clawed golden dragon, the Golden Light Spell, the Five Thunder Rites, the Twin Hands, and more. The System even sends the zombie king into tombs. And so begins a series of utterly ridiculous adventures.
