The list Qin Lan brought had quite a few supplies, but all of these needed to be exchanged with vegetables produced in Chen Xin's shelter. The list also included the exchange ratios deemed suitable by the special police team after discussion.
Chen Xin had no objection to the resource exchange since it was beneficial for him as well. However, he did have different opinions on the exchange ratios.
"A hundred pounds of fresh vegetables for five bags of cement? This ratio is acceptable." Chen Xin checked each exchange ratio marked on the list: "But the one for rebar is a bit exaggerated, isn't it? It takes twenty pounds of vegetables to get a single piece of rebar?"
Rebar was extremely useful for Chen Xin; needless to say, reinforcing the door of the shelter required rebar concrete.
