National Survival: I Rely on Industrialization to Become a God

[Starting with a broken wooden house + industrial black technology + universal time travel + invincible crushing] Billions of people around the world have been forced into other worlds to survive. They gnawed wild fruits when they were hungry, drank muddy water when they were thirsty, and fought against strange beasts with their bare hands. Everyone was in danger. Jiang Han awakens the god-level industrial tree at the beginning and directly lights up the entire technology tree. While others were still grinding stone axes and building straw sheds, he was already smelting iron in earthen kilns and roaring steam engines. While others were still fighting for their lives with wooden spears, he made guns and cannons on an assembly line, and heavy cannons pushed through the wilderness. While others were still fighting for a piece of meat, he built steel fortresses, grid railways, and automated factories. From handicrafts to the steam age, from the electrical age to nuclear energy and aerospace, we have been on a wild ride without looking back. Alien beasts are coming? Tanks plow! Alien invasion? Missiles wash the ground! A natural disaster is coming? Planetary Defense Shield activated! Jiang Han relied on his invincible industrial system to gather survivors, build a mechanical army, and overwhelm the entire survival world. While everyone was still struggling to survive, he had relied on industrialization to become a god!
