Gu Shanhai quickly obtained the information he needed after interrogating the two people separately. Since they were questioned separately, their statements could be cross-validated, and it must be said that both were honest enough, as the answers obtained did not pose too many issues.
Therefore, he did not kill any of them. Instead, he used their identities to quickly reach the Xuanwei Sect's base.
At this time, there were not too many disciples within the base; most had been dispatched to Fengtai Village, leaving only a small number to maintain operations.
Then he naturally knocked them out and left them behind. He definitely wouldn't kill them – the pair were too honest for him to do so. He could use their identities to cause trouble for Xiang Ting.
Xiang Ting was currently in Fengtai Village, not inside the Xuanwei Sect; thus, Gu Shanhai could not simply go to the front lines of Fengtai Village to kill him.
