The protagonist Lin Yuan was reborn one month before the apocalypse broke out, and awakened the only "god-level infrastructure system."
It can consume specific materials (steel bars, cement, energy crystal cores, etc.) To infinitely upgrade any building from level 0, giving it functions such as military barrier-level defense, self-sufficient ecological cycle, and automated weapon turrets.
Plug-ins such as "Water Purification Module", "Soilless Cultivation Module", "Energy Core", "Medical Cabin", and "Manufacturing Workshop" can be unlocked and installed to turn the fortress into a multi-functional super base.
The system interface can display all data such as the fortress's durability, energy reserves, material inventory, and spatial structure in real time, down to the details of the output of each bullet, which perfectly fits the "microscopic perspective."
As long as you have the materials, you can upgrade with one click, the effect will be immediate, and the fortress will be indestructible.
