With Double Doors, I Build an Empire on Which the Sun Never Sets

A two-way boundary door hidden in the rental house connects the prosperous modern Blue Star to the dark and wild extraordinary continent of Essolon. Lin Yue, a young man from the bottom, has no system, no cheats, and no chance. He only has the bottom-level survival logic and industrial cognition of modern civilization. This is a modern world with perfect rule of law and abundant supplies. Over there, it was a troubled feudal era where the aristocracy was divided, theocracy was restricted, tribes were rampant, and human lives were like grass. The refugees starve to death in the wilderness, the lords slaughter the people wantonly, the church monopolizes education, and the extraordinary overwhelms the ordinary. Others travel to other worlds to seek skills, seek opportunities, and strive for unparalleled cultivation. Only Lin Yue returned with a civilization and did not take the path of personal invincibility, but only became a subversive of the times. Improve farming and mulberry trees, eradicate famine, and bring peace to the people through farming; Establish household registration, enact laws, promulgate new regulations, and establish the world with systems; Build workshops, smelt hardware, manufacture custom-made ordnance, and break the barbaric wilderness with industry; Establish an army, pacify tribes, defeat lords, resist theocracy, and bring order to the chaotic world. Blue Star's materials and technology reduce dimensionality and crush the backward feudal shackles. The magic mines, exotic animal resources and secrets of ancient civilizations from other worlds feed back into the real world, creating two-way blood, in an infinite cycle. Starting from a group of refugees in a desperate mountain pass, they gathered people's hearts, built settlements, built city-states, established royal courts, and established dynasties. Use mortal industry to defeat the thousand-year divine power; With the torrent of the two realms, it swallowed up all the realms and heavens.
