Fantasy: I Have a Knife That Can Kill Everything in the World

[Relaxing and funny fantasy, no harem, passionate, I am going to take action...] I have a knife. When I draw the knife, I can distinguish between life and death. If I don't drink the blood, I won't return it. With the knife in my hand, I have the world... I have a sword that can move mountains and rivers, break up the world, cut down three thousand avenues, and cut off all injustices in the world. Women will only affect the speed of my drawing the sword... The name of the sword is "Zhanjue", "Kill everything"! There is reincarnation in the way of heaven, and I can cut it off with one blow...
