In this chapter, we learn that the brat has reached the level of the "bone- forging realm" , but his strength is still only at the "level 6" level. This means that he's not strong enough to hurt people if they don't have the right amount of strength. He's too weak to stand watch over his sister, who's about to be "stripped naked" . He wants to know if he can count on Dong to protect him. Dong tells him to grab his brother and run away. He also tells him that it's better to watch his sister being stripped naked than to stand by and watch her being raped. He tells Dong that they're "sworn brothers" and he'll finish Dong after he takes care of his sister.
