After two days of being unchallenged, Luo zheng returns to the arena. He is surprised to find that no one has challenged him, and wonders why ziyu is still looking for him. He tells her that he is challenging her, but that he will not wait for her to catch up with him. She is not stupid, and he tells her to hurry back to master her. He says that if he catches up with her, he will challenge her on the third level, but he will wait for the chance to catch him on the fourth level. He hopes that they will meet again, and says that he believes that they can reach the tenth level together in no time. He hears that the higher ups have ordered an assassin to kill Luozheng. He asks if he will be able to defeat the assassin, and the answer is yes. He explains that the assassin will be a nightkin, a kind of suicide warrior. Nightkin are natural assassins, but because they are weak in combat, they cannot compete with human warriors
