I Signed in the Hundred Ghosts in the Horror Reincarnation

Su Ye was pulled into the Abyss Wheel - an extra-dimensional space where people are thrown into horrific copies to die. Others just want to survive, but he is bound to the ghost book, and he can sign in and collect ghosts every time he enters a dungeon. While others ran to the safe zone, he burrowed into the ghost cave. The more dangerous the place, the stronger the ghosts that appear. The signed ghosts can help fight, explore paths, and evolve. The ghost army is getting bigger and bigger, and he is getting stronger and stronger. But the ghost book has a secret: it is the heart fragment of Yuanlun. The more you sign in, the closer you are to being devoured. When 108 ghosts are collected, the ghost book returns to its place and the holder will die.
