The six realms are full of ghosts and chaos, murderous intentions are everywhere, and people are killing each other. In the past 200 years, legends about the Youyou Ship have been circulated here. A huge shabby ship has been seen from time to time in all corners of the world, sometimes in the misty black sea, sometimes in the dark and deep virgin forest, and sometimes in the corner of the sky with lightning and thunder. ... There will always be a person on the boat who is dressed in weird clothes, and his face changes endlessly. Sometimes he is a charming and charming woman, sometimes he is a handsome man, and sometimes he is a child with murderous eyes... "They" all wear half masks, with a living human face on the mask. Only when killing people, the half of the mask will disappear temporarily. What kind of face is under the mask? Who is he/she, and why are there ghosts everywhere he goes? Why was he so calm when he left? All the mysteries are about to be revealed...
Concept: Sneaky things are everywhere, evil spirits are everywhere, but there is always a light of justice that kills all hidden evils.
