1. In this activity, you can exchange a building you don’t like for a high-end building you like.
2. Open the Craftsman Exchange in the activity at the bottom of the main interface and find the building that the player likes.
3. Click on the building and confirm the exchange button below, and then you can choose to exchange it with the items in your backpack.
4. The quantity that can be exchanged is limited. For example, Youhuangli and Yunxingruixiang can only be exchanged once, which requires 15 buildings.
5. But the Category C buildings below are much simpler. They only require 4 buildings to redeem, and each can be redeemed for 5 pieces.
