Zhang Mufang took the CAD system to travel through a magical alien world, and the monsters destroyed the city at the beginning.
He rebuilt slums with prefabricated boards and improved city walls with mortise and tenon structures. Magicians sneered: "How can mortal bricks and tiles be as eternal as magic?"
When the beast tide came, the magic shield shattered, but the city wall remained unmoved; earthquakes tore the earth, the mage tower collapsed, but his brick and concrete school building was as stable as a rock.
The dwarf royal family held up the drawings and asked for cooperation: "Master, can a floating city be built?" The elf elder bowed: "Please design an ecological dome for the ancient tree of life."
He built a cross-sea bridge to connect the mainland, and created a magic elevator to subvert air combat.
The old gods awakened from the abyss, and the magic legions were routed like mountains.
Zhang Mufang started the final project, millions of craftsmen lined up behind him, and the torrent of steel built a defense line of thousands of miles.
"Gentlemen - this is a barrier to civilization, humans will never be slaves!"
