Not having anything else to distract his attention, Chen Mu's full attention was focused on the swordfish battle challenge. But the situation with the swordfish battle challenge was not the same as what he'd run into before, since the challenge was quite dangerous. That could be seen from his first experience which had left seven or eight red welts, which hadn't gone away yet, and which were slightly painful every time he pressed them.
Chen Mu wasn't going to dare to go in and try it again willy-nilly. Even so, Chen Mu had no thoughts of beating the drums of retreat. No way! He could slowly exert himself. Where there was danger, he could choose the relatively safe way. Doing nothing was the most messed-up choice.
