Eternal Night Is Coming, I Build a Heavy Equipment Base

After the natural disaster, day and night rotate randomly, and during the dark night period, countless strange things wreak havoc on the surface, while human beings are struggling to survive. Chu Ya obtained the [Structure Lord] system through time travel and built his own refuge base bit by bit in the ruins. City walls, watchtowers, fortresses, Buildings are rising from the ground. From cold weapons wooden towers to steel machine guns. From thatched huts to concrete fortresses. As night fell, his eyes turned into a torrent of data: Can see fire blind spots, structural stress, member status, energy flow... But he can't see the future, so he can only rely on time and again to fight for his way out of the desperate situation. During the day, he drew pulse rifle drawings and gave them to craftsmen; Send the "Iron Rat" robot deep into the edge of eternal night to dig for strange crystals and explore ruins; While others built their base on the surface, he dug thousands of meters deep—— Underground is water purification, planting, and finally human fire; The surface is a steel cemetery composed of railguns, power grids, and rocket nests. Is this the last line of defense for mankind? No! "I am not defending, but using order to reconstruct this wasteland."
