Unlimited opening, unlimited power! The mutated mobile phone has a magical app download! All kinds of buildings, can rise to the sky, can sneak into the sea, can be hidden… hidden secrets of the big!

Tang Zhen’s ability to build a city is… Building a city, playing with explosives, crushing the ground and grabbing the ground.

Tang Zhenduan sits on the top of the mountain, and at his feet is an endless floating city, guarded by dragons, surrounded by angels, and countless giant guns stand in the sky!

In the depths of the ocean a million miles ahead, it is another big 6-level building that is waiting for his conquest!

The protagonist transmigrates into the body of the son of a marquis in another world, inheriting the marquisate's title, developing the marquisate's territory, leading surrounding nobles, fighting against his own kingdom and neighboring countries, and ultimately becoming a grand duke. The protagonist has no system, no special abilities, and no harem; he conquers the world solely through his 21st-century knowledge and millennia-old Chinese military wisdom.

A blood-stained contract, a mountain of gold waiting to be mined, a precarious kingdom. He is an engineer, a foreman, the last hope of all the oppressed. He is an ambitious man, a capitalist, the most unstable piece on the chessboard of the nobility. In his left hand is a blueprint for overturning the world, in his right is the soft hand of his daughter. Vand, no, Edwin VanCleef, will use steel and concrete, gears and levers, to reshape the order of this world. "Truth lies only within the range of siege guns. And I am responsible for defining that range."
