Cui Yingyu had always thought that Liu qingrui was related to mu accord or chillywind Ridge. He thought that Liu qingrui was likely to be from one of these two sects. At first, cui Yingyu had thought that Liu qingrui was from the ten thousand poison sect, because Liu qingrui was also very good at using poison.
However, he didn't expect that Liu qingrui wouldn't show any mercy when killing people from the thousand poison sect. The first person he killed was from the thousand poison sect. Later, when he took on a mission, he even killed a member of the thousand poison sect in their territory. It was easy to imagine how arrogant he was. It was also because of this that cui Yuyu thought that Liu qingrui wasn't from the thousand poison sect. He was most likely from the elegant wood Pavilion or the chillwind Ridge. They all knew how to use poison.
