Gu Xijiu was present with the clan leader, who had brought the villagers back to the place where they had once hated so much. That night, Gu Xijiu had made direct contact with the clan leader to inform him about her current situation and that Yun Yanli might someday use the people against her.
The clan leader was an experienced man, so he immediately knew what to do. The villagers did not possess any great powers but were solidly united. Moreover, they respected the clan leader's every decision. Hence, the clan leader had gathered all of the villagers late at night and seized the chance to run away from the city while everything was in a mess. It was great timing for an escape, as the periodic blood of rain had just passed.
