In his previous life, he died with hatred in the bloody storm of the Mythical Era; in this life, Xiao Yu was reborn with the memory of the doomsday, and resolutely sold off hundreds of billions of assets three months before his spiritual energy was revived, transforming into a "crazy collector" just to compete for the ancient mythological heritage. When he spent 3 billion to buy the Dunhuang fragments, buy out the nameless peak of Kunlun Mountain, and salvage the Demon-Slaying Sword and Dinghai Pearl, everyone thought he was crazy. Until the cracks in the Nine Nethers were torn open and the ancient ferocious beasts appeared. Xiao Yu stepped on the dragon, held the Xuanyuan Sword, and led a hundred thousand Yin soldiers. As the guardian of China, he roared: "The land of China will not allow monsters to get involved!" A battle in the mythical era that rewrites the rules of the world begins.
