Li Shiming used the Guest Official Jade Plate to get in touch with Xin Jingyun, and then arranged a meeting place before taking Jian Wuwei there.
He really didn't want Jian Wuwei to be out and acting alone anymore. In Jian Wuwei's weakened state, he might suffer at the hands of any Nascent Soul cultivator he encountered, and Li Shiming couldn't guarantee that he could save Jian Wuwei every time.
Li Shiming was piloting a Fourth Grade Upper Stage Flying Boat, carrying Jian Wuwei. Although Jian Wuwei had taken Healing Spirit Pills, the long-term damage to his core wasn't something that could be easily healed and required long periods of rest.
Li Shiming displayed the marker of Central State Commerce on the Fourth Grade Upper Stage Flying Boat, choosing not to use Ten Thousand Beast Sect's marker.
Even though Jian Wuwei was in a weakened state, he noticed this detail, which made him worry. The marker of Central State Commerce wasn't something that could be casually used.
