Because the poison hadn't been removed from Mei Li's body, the longer it remained, the greater the danger to her.
Although Ding Fan had previously sealed Mei Li's major acupoints to prevent the spread of the poison, it was still Giant Cicada Toxin—one of the top ten strange poisons in the Cultivation World, which was even more significant on Earth.
Thus, after parting ways with Cheng Bufan in haste, Ding Fan returned to the military district guesthouse.
Since Mei Li's wound was above her chest and treating it might be inconvenient, Ding Fan straightforwardly decided to keep Mu Zi with him.
At this moment, Mu Zi was quite willing to follow Ding Fan, and she wouldn't even mind sleeping by his bedside at night, if he agreed.
Following Ding Fan meant having meat to eat.
Considering how short a time Ding Fan had been in Yanjing, Mu Zi now had her own Spiritual Artifact and Magic Storage Instrument. If she followed Ding Fan for a few more days, wouldn't she become a little rich girl?
