When Fang Yuxin and the others caught up, these people hadn't returned to the base yet. The three of them, invisible, followed behind, seizing the chaos caused when these people entered the base, and narrowly infiltrated Beishi Base. Then they quietly went to the homes of the three unlucky souls whose identities they had borrowed, released them, and compensated each with some crystal cores.
Oddly, neither the Qu Family nor the Qin Family sent anyone to cause trouble, allowing the three of them to breathe a sigh of relief. After all, if their borrowing of identities caused trouble for these people, they would feel very guilty. Before leaving, the three of them specifically found a way to reveal Zhao Qiankun's background to Qiu Yiming, but how these two would struggle afterward was no longer their concern.
