Feng Yi was preparing for departure while also waiting for Wu to return.
After returning to Yang City from the island, Wu immediately delivered the stored poison to the Ancestral Factory, coincidentally encountering this matter, so he would bring the medication.
More than two hours later, Wu came back, bringing with him two boxes.
Looking at the time, it should have been right after Feng Yi confirmed the matter with Geng that Geng immediately handed over the medication to Wu.
Feng Yi looked at the two boxes Wu brought back; one was obviously a temperature-controlled box for storing medication.
Feng Yi planned to inspect this box personally.
During his time in Tuo Jia Town, Feng Yi had heard Pan Weining mention a problem his Uncle Wei had encountered.
Taking Uncle Wei's lesson as a precaution, Feng Yi had to make sure once again, did this box maintain temperature, and was it functional?
