My System Wants to Fix Me

The protagonist becomes a system without intelligence. He can't speak, he can't do anything, he can only follow the set procedures. But this system can replace everything, no matter where it is? Whether it's from Journey to the West, Ancient Times, or Fox Demon, they can all be perfectly redeemed and attached to the night host. Moreover, even after the system disappears, it will not disappear. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
