After opening the system panel, he immediately navigated to the shelter interface.
[Upgrade Shelter Material]
Lin Yue saw this option.
[Upgrade the shelter's exterior walls and internal structure material to stainless steel, confirm? Requires 700 units of stainless steel]
That's really a lot.
Lin Yue glanced at the 598 units of stainless steel in the Storage Space, then went down to the basement's warehouse and moved the remaining 102 units of stainless steel into the Storage Space.
Although these could be used to build a greenhouse, the most urgent thing right now is the shelter's stability.
This is a very important issue; he doesn't want the comfortable home he painstakingly built to become rubble and ruins under a hailstorm or a fire tornado.
Moreover, even if he gathered all the materials for the glass greenhouse now, he could only wait for the disaster to end before starting construction.
"Confirm upgrade."
