You Were Told to Exile Her, Not Let Her Become Empress of the Northern Frontier

Synopsis: [Dual transmigration + Industrial Revolution VS biological mutation + Deposed Empress's comeback + War epic]

Shen Ning, a 21st-century polymer materials expert, transmigrates as the deposed empress of the Great Liang and starts out exiled to the bitterly cold northern frontier. She thinks she's been dealt a living hell, but she has an encyclopedia of industrial knowledge at her fingertips. On frozen soil, she builds an iron city called Winterhold. Smelting steel, making cement, manufacturing guns and cannons, developing infrastructure... She thinks she's playing a single-player civilization-building game, where climbing the tech tree is all it takes to sweep across the Six Kingdoms.

Until one day, green toxic fog blankets the border, and tens of thousands of undead troops surge in like zombies. Only then does Shen Ning realize in horror that there is another player in this world.

Su Bai, a top chemistry prodigy and a madman who crawled out of a mass grave, is the mastermind behind the Western Chu Empire. He has no need for steel; he believes in chemistry. He uses heroin to control the imperial court, poison gas to reap lives, and biological viruses to create an army of the undead.

Shen Ning: "I want to bring light and warmth to this world, along with the order of industrial civilization." Su Bai: "Too noisy. I want to silence this world and turn it into a specimen in my petri dish."

When a steel tide collides with a biological nightmare, when heavy industry clashes with black magic, this is no longer a palace struggle for the throne. It's a fight to the death between two modern visions in another world!
