Hidden Knife in Hand

I never thought that time travel would happen to me. I want to go back. But the empress who hired me to kill these twelve strong men from another world said: "When you are born in this world, you can only leave it by dying. If you really want to leave, why don't you try this way?" I admit that I am tempted. Not to the Empress. But what she said. It rains in the east at night, shines in the west, wind, snow, thunder and lightning come on both sides. Southern Book, Northern Wilderness, beautiful spear. The sword is fire, the sword is empty, and the stick is empty. This jingle refers to the thirteen strong men in the world. I am Daokong. Although ranked lower, it is still among them. I took the order today. The endings of the twelve people remain the same, but there is one more. It's me.
