I Can See Through Evil Spirits

Ghosts have no place to come from, no way back, and cannot be killed. The only one who can fight against ghosts is ghosts. The evil ghost cannot be killed, but it will be extinguished and turned into strange objects. However, it can also revive and become a evil ghost again. In order to fight against the evil spirits, humans have to transplant strange objects transformed from evil spirits into human stomachs to control the ghosts. But once revived, the evil ghost will become even more terrifying. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
