Liu Hun wasn't clear about the rules of Sin City. Originally, he thought this so-called little sister apprentice would know what the task was, but to his surprise, she told him that tasks are randomly issued by people within Sin City. The premise is almost all tasks involve heinous acts, otherwise, one would absolutely not be allowed to enter.
The reason Sin City is called Sin City is that it's the source of evil. Therefore, to enter, one must commit acts that are reprehensible to both humans and gods, or else they are not worthy of entering.
Faced with such a rule about Sin City, Liu Hun wasn't too surprised. After all, a city like this naturally should have its own uniqueness; otherwise, it wouldn't stand alone in such a place.
From the city where Liu Hun and his group got off the train, they had to take a cab to Sin City. So, without wasting any time, Liu Hun immediately hailed a taxi heading towards Sin City.
