Li Yifei had no reason to refuse the matter at hand. Most importantly, those who were after Su Mengxin had already come knocking, and Li Yifei couldn't afford to be careless. In a crucial place like Capital City, it's extremely difficult for any power to pull strings, but in Mile City, the security was far from robust, so various powers found it too easy to infiltrate. Relying solely on the security guards Su Mengxin brought with her was hardly sufficient for her safety.
Fortunately, Su Mengxin didn't come here with the intention to attend any events. As long as she was with Li Yifei, that was naturally the best possible situation. If the two of them were alone at home, Su Mengxin would've been very happy about it. However, Ning Xin'er showed up first, shattering the opportunity for Li Yifei to spend time alone with Su Mengxin, so the three of them simply continued moving the remaining stuff.
