Working stiff Lin Fan transmigrated to become Ye Wushang, the holy son of the demonic sect, but he couldn't even understand the immortal cultivation techniques. Who would have thought that after a series of outrageous operations, he actually cultivated the Primordial Force where demonic energy and sword energy coexist! From being at loggerheads with Ling Xiao, the holy son of the sword sect, to teaming up to venture into a secret realm, the two slew giant beasts and fought corpse soldiers, but gradually got embroiled in a conspiracy spanning both sects. The more the technique was practiced, the more wrong it became, but his strength grew stronger and stronger.
