After dealing with the matters of the [Market], Zong Shen returned to the Lord's Courtyard.
He began upgrading the Territory Storage Box. As the fundamental storage space of the territory, the upgrade difficulty and resource consumption of the Territory Storage Box were not considered high.
Zong Shen easily upgraded the Storage Box to level 5 in one go, and with the level 2 [Storage Shed Type I] technology, the territory storage grid's capacity reached as much as 220 grids.
After occupying 58 storage grids in the Storage Box, Zong Shen successfully stored 57,864 units of iron. His personal storage grid and backpack storage grid were finally re-organized.
Then, he rushed to the [Tier One Territory Technology Research Institute], upgrading [Defense Studies Type I] to the second level, further increasing the durability value of territory buildings.
Technology research takes some time, and once Zong Shen confirmed the upgrade by consuming resources, he could ignore it for a while.
