If it is the latter where the elixir thief just coincidentally passed by in the abandoned courtyard last night, then Lin Ze has to find that elixir thief again. And Qiu Ling, or Meng Xing, has to plan again since if this happens, Lin Ze would not necessarily be with him to investigate. If this happens, then Meng Xing has to plan more carefully since he might have to bring Qiu Si with him. After all, Meng Xing doesn't know when will the poison in his body – the Bianhuan Poison, attack him again.
It is not that Meng Xing is weak. But, he just wants to have assurance that he can still return alive. He doesn't want to die, especially in this unknown land. He has already regarded the imperial capital as his home, and if he really dies, then he wants to die in his new home.
"Hm?" Lin Ze muttered when he finally heard a hollowed sound. "Is this it?" he asked as he knocked on the wooden floor again. "Hey." He called Qiu Ling.
