Ember Age: Road of Steel

In 2147 AD, the earth's resources are exhausted and human civilization is on the verge of collapse. The last interstellar expedition fleet carried thousands of mechas, drones and all industrial equipment, passed through the wormhole and arrived at a strange planet called "Qingming". There is no oil or nuclear energy here, but there is an energy that subverts the laws of physics - spiritual energy. What is even more shocking to mankind is that there is a real civilization of cultivating immortals on this planet. The golden elixir monk can wield a sword for thousands of miles, the Nascent Soul can move mountains and fill the sea, and the old monster who turns into a god can change the color of the world with a single thought. The technologies that humans are proud of are like children's toys in front of these "natives". However, humans have no retreat. The fleet is running out of fuel, and tens of thousands of our compatriots are waiting for survival. The scientists made a crazy decision: to use the "beast fire" on this planet to replace traditional fuels, reconstruct the mecha armor with the strength of "ten thousand-year iron wood", and forcibly integrate the alien fire and monster materials of the cultivating civilization with human steel technology - thus, the first generation of "exotic fire mecha" was born.
