Rebirth at the End of Ming Dynasty: but I Am the Cube Immortal!

Reborn in the late Ming Dynasty, he was trapped in a cubic meter of air wall at the beginning. In despair, Su Bai found that he had become a "square fairy": he could pull up trees with his bare hands, synthesize them out of thin air, and carry everything in his backpack. When the hungry man was chewing the bark of the tree, he was already thinking about the layout of the wheat automatic farm; when the bandit was wielding a rusty knife, his diamond sword was enchanted with sharp V. From a cage, to a majestic city, to a transcontinental railway network... He used the rules of MC to reshape this collapsed era. Li Zicheng: "He is immortal, how can he fight this battle?" Huang Taiji: "His city wall cannot be blasted open by our red cannons!" Emperor Chongzhen: "Immortal, can my Ming Dynasty... Be recharged to extend its life?"
