Is My Roommate Still a Bitch? I Have a System That Starts Spraying Directly

Who knows! After being reborn and returning to the university, my roommate was cheated out of money by being a bitch, and he was cheating on the girl Su Ya. But I, Lin Ye, with the hatred of being killed by the Japanese in my previous life, was bound to the defense-breaking system! As soon as the system rang, it started spraying on the spot. Kill people, avenge blood, and collect harems. Whatever the devil owes me, I will definitely get back the original money and profits!
