I am a death cleaner in the future world, specializing in removing traces of death from the homes of rich people. The rich man's wife died in the bathtub, and I expertly cleaned up the blood and decomposed the body. Until a drop of bright red blood is found that cannot be removed. It kept regenerating and even crawled toward my gloves. The company suddenly ordered: "Stop cleaning up and eliminate traces immediately!" I lowered my head, and the drop of blood was slowly seeping into my protective clothing.
