Back then, the people who had surrounded and annihilated su Wu were from the tianwaitian martial arts Research Institute. On the night of his death, most of the people in tianwaitian were alarmed.
It was also because of the news of su Wu's death and the reappearance of the God destroying technique that song qingxiao was able to escape from Qian Shan.
Killing a participant in the same stage in the trial would give priority in the exchange. This was a rule that song qingxiao had figured out by herself based on past situations.
She originally thought that the rules of the trial were also applicable outside of the trial. After hearing su Wu's words, she realized that killing someone who was also a trial-taker outside the trial arena only had a chance of obtaining that person's cultivation method and secret technique.
