At this moment, Liu Yan and Chu Long were planning to upgrade the city walls.
To upgrade the city wall to level 2, the materials required were 1,000 cubic meters of origin wood above C-grade, 100 origin stones above grade C, 100 cubic meters of wind rock of any grade, 100 wind crystal stones above C-grade, and 100 cubic meters of refined iron above C-grade.
The materials needed to upgrade the city wall to level 2 were all common materials that could be collected near Origin Territory.
However, the amount of these materials was undoubtedly a little too much.
After a day of harvesting, they harvested all the wind crystal stones in the wind crystal stone vein. After the team members had finished upgrading their respective wooden houses, they only had a little more than 200 wind crystal stones left.
