The mountain boy was driven out by his mad master to fullfill a gambling debt, but he got caught up in a dark conspiracy that had been lurking for a thousand years. Stumbling and bumbling, the young man gradually unraveled the mystery of his origins, gained the power of the ancients, and finally opened the portal to another world, not realizing that the other world was the true source of darkness! By then, the other world has been consumed by darkness and become unrecognizable! The young man decided to take up the duty of a thousand years, and resolutely stepped into the door to the alternate world! (Source: Tencent, translated)
