Chapitre 3307: Snake fruit tree's roots (1)

The entire Free Trade Hall wasn't made of stone like Zhao Hai had expected. It was made of metal. There was a huge metal shelf here. From the outside, one could see what each floor of the hall was like.

Zhao Hai was stunned when he first saw this, but he soon understood that these cultivators didn't need glass. Whether it was wind or rain, it didn't affect cultivators much. That was why the free trade Hall only had a metal shelf.
