Gu Yang accidentally traveled to a world full of ghosts.
This is not the most desperate thing, the most desperate thing is... The ghosts in this world are not the same as the ghosts people tell about by word of mouth.
Because ghosts in this world cannot be killed. The only ones who can deal with ghosts are ghosts and have insight into their laws.
Just when the ghost was about to kill Gu Yang, he unexpectedly got a mysterious sign-in system.
In order to survive in this desperate world, he continued to be exposed to various supernatural events and signed in with ghosts to become stronger.
It's not too much to order one for yourself [laughing evilly]
