Doctor Cao was close by, so he arrived after them.
When Doctor Cao arrived, he was carrying a metal box in his hands. The metal box contained Doctor Bai's belongings.
There would not be any inefficient meetings in the base. Once a meeting ended, there would be a conclusion. Once they decided who to hand over the items to, they would have to give Doctor Bai's belongings to that person. There was no need to go to the warehouse to register and take them.
Before the other staff arrived, Doctor Cao placed the box in front of Jiang Yue.
When the decision was made, Jiang Yue, the supreme commander, would have to hand the relic to that person.
