Raft Survival: Start with a Fishing Rod

I've read Chapter 5, and here's a little summary! Prices are confusing, material usage is confusing, shark meat is 1:1 wood? Can wood and food be the same amount? Later, the raft was expanded from 4*4 to 4*6 with the expansion of 1,030 pieces of wood. Why is the raft so valuable? Your book doesn't even mention how much wood is needed to expand the area of ​​a square raft, and the writing is so messed up that there is no reading experience at all. .

More than twenty chapters are charged for studio writing?
