Great Ice Age: Inheriting the Lost Civilization at the Start

The thirteenth year of Jianhe, the thirty-first year of the Great Ice Age. Rivers were blocked, the ground was frozen, food was exhausted, and people began to eat things they shouldn't. When Lin Yun walked out of Beishan Garden, he was wearing a cotton-padded jacket with seven patches and not a single grain of food in his pocket. But he carries in his mind the legacy of an entire lost civilization. Thousands of rolls of technical drawings - from burning a brick to building a steam engine. A lost body-training technique - one punch can kill a wolf, two punches can kill a person. He used plant ash and lard to make the first piece of soap, in exchange for thirty kilograms of grain. Then came papermaking, ironmaking, gunpowder, textiles, cement... Deserted villages become towns, towns become city-states, and city-states become empires. Local bully blocking the way? Crushed. A noble family is under siege? Puncture. The Five-Nation Alliance forces are suppressing the border? Just in time to save him from having to come to the door one by one. Because the Great Ice Age waits for no one. Twenty years from now, the real winter will engulf everything. By then, those who have no city walls, no granaries, and no industrial power will all die. So he had no time to be polite to anyone. Anything in the way is crushed. If you can use it, bring it. He wants to build an empire from scratch in the cold weather for everyone to survive.
