The mysterious young man Huang Yu was inexplicably sent to a place called the Second World. Facing the imminent invasion of the First World, he was told that he must stand up and resist, otherwise he would be permanently assimilated to the Second World and would not be able to find his way back.

Since then, there has been a murderous god in the world. He is arrogant in the world, plotting and scheming, and standing in the way of a tiger. Anyone who blocks my way will die!
