"I want to become a Dusk mercenary too," Lin Yaoyao said to Qi Xiangyun as she looked inside the medicine box.
Liu Hongzhao had completed a mission as a Dusk mercenary and had directly encountered other worlds. The world she visited was similar to theirs, except that it had no Supreme Demons and the situation was not as dire as in their world.
The main conflict there was against the Boundary Breakers, whose presence hadn't yet greatly affected that world.
Liu Hongzhao had harbored deep hatred for the Boundary Breakers, vowing to kill any she came across. Upon her return, she even brought back some martial arts rare manuals from that world.
