Version 1.32 This is my war. How can I bargain with a businessman?

If playing is the most tragic role in my war, I think it may be a businessman. Players can use Katia's bargaining skills, use the least items, and exchange all the things of merchants. Here are the specific trading skills.

1 First of all, in the open game, you have to search all the places on the first day to find the big medicine.

2. Businessmen usually come at 8: 00 ~ 10 on the second or third day, and ask Katia to click on the transaction.

3. Here, first change a big medicine +4 bandages for other items.

4. Then change the bandage for a big medicine. Because of Katia's bargaining skills, bandage = big medicine value, and big medicine is greater than bandage value.

5, so repeatedly, if you encounter high-value items that cannot be exchanged, such as small medicine, use big medicine+meat for bandages+small medicine.

6. I changed it again and again, and finally moved the businessman empty. And I only used two pieces of garbage, and I got everything from the businessman.
