Back to Ancient Times: from Loom to Torrent of Steel

Back in ancient times, Ye Ji accidentally created the most powerful country in the world. No clothes to wear? It's okay, a new type of loom was invented, cotton cultivation was promoted, and everyone in the world had clothes to wear. Nothing to eat? It's okay, we'll travel across the ocean to find new crops and carry out agricultural transformation so that everyone will have something to eat. Is the ocean too far to cross? It's okay. Inventing a new type of warship and traveling across the ocean is not a problem. The enemy's city wall is too high? Fine. Cannons plowed the fields, tanks attacked the city, and it was enough to tear down the city walls. The enemy cavalry ran too far to catch up? It's okay, no matter how fast you run, you can still outrun a plane.
