Cannon Fodder Counterattack Investigation System (Novel)

“Is this really a fucking cannon fodder counterattack system???” Zhou ZiRuo transmigrated into a game and became a shapeshifting, cannon fodder, baby fox demon.

As Zhou ZiRou wearily investigated the supernatural cases, at the same time, he walked down the grand path of counterattacking the protagonist and kicking him to the curb...
