Unexpectedly, its host is actually a full-level boss who pretends to be a pig and eats the tiger. He tears up the fake heroine and beats up the scumbag. Even the master of the main system gives in. From then on, it hugged the boss's legs and lay there, and reached the pinnacle of life. Main system: "Serve this ancestor well and there is no need to come back!"
