Liu Yan immediately opened the level 3 warehouse upgrade panel.
[ Level 3 warehouse ]
Upgrade requirement: Level 2 territory
Upgrade materials: 1,000 cubic meters of origin wood (C-grade and above), 1,000 origin stones (C-grade and above), 100 wind crystal stones (C-grade and above), 100 cubic meters of refined iron (C-grade and above)
Seeing that the materials for upgrading the warehouse to level 3 were all basic, Liu Yan was relieved.
Although the number of basic materials needed to upgrade the warehouse to level 3 had increased a lot.
Fortunately, there were many materials in the warehouse of Origin Territory, so they could afford to be consumed.
Immediately, Liu Yan, Luo Qingcheng, and Chu Long took out the materials needed to upgrade the warehouse to level 3 using their spatial rings. They placed them in the open space outside the warehouse and began to upgrade.
