BL chinese novel where the mc transmigrated into a book as villain and was killed by the protagonist, but then reborn into another character in the book. This cannon fodder character was seen by others as an idiot who wore a mask/make up/face paint but later mc found out this character had the same face as his previous character. Right after his rebirth mc almost become a sacrifice to a demon lord. He escaped and eventually found out while other people slandered his name (the villain character), the protagonist defended him and was in love with him. The protagonist also carried mc's corpse everywhere he went in a coffin that was shrunk into a necklace. It's a cultivation world. The MC is pretty strong. The mc and the protagonist are xiongdis.
