Mechanical engineer Lin Chen opened his eyes and found that he had become the most despised "demon-free" in the Essos continent. Here, the elemental mage can control the wind and rain, and the rune craftsman can drive the steel colossus, but he can't even master the most basic fireball technique. When the void invaders in the "Star Boundary Rift" broke through the seal, and when the forces of the three realms were jealous of the "Ember Fire Code", Lin Chen tightened the wrench in his hand - others used magic to chant, he used gear transmission; others relied on blood to awaken, he relied on formula calculations. "So what if there's no magic?" He knocked on the homemade steam staff. "In this collapsed world, I'm going to use the laws of physics to knock on the door home, and by the way... Save you."
