Rule Horror: Who Says I'm Sick?

(The Strongest Dao Arts System) The System bonded with its Host, only to discover that the Host was still a mental patient. When it tried to sever the bond, it ran into a glitch and couldn't disconnect...

The System also wanted to treat the Host's mental illness, but the Host didn't believe there was anything wrong with them. So, with no other choice, the System could only protect the Host. Whenever the Host faced something supernatural, they basically got whatever they called for: the System automatically equipped them with all kinds of Daoist attacks and defenses.
