Magic Invades the Wasteland, I Climb the Technology Tree Alone

"My name is Shiloh. I was accidentally reborn into a wasteland world after a nuclear bomb and magic attack. I became a slave at the beginning." "Just when I was almost bought by a mutated female dwarf with a beard, a group of beautiful elf ladies rescued me and said they would take me to meet their queen." "I even thought about how I would eat soft rice in the future, until I was taken into their palace, a dark bunker..." "Hiss~ There's something wrong with this place..." … When Xia Luo woke up, he found that he was reborn in a bizarre wasteland world, and received an exclusive game panel, becoming the only [Mechanic] in the world. Hundreds of years ago, a magical alien world invaded. In order to preserve the fire of civilization, humans detonated all nuclear bombs around the world. Under the double baptism of radiation and magic, the planet turned into a wasteland. The radiation even caused the monsters that had traveled through time to mutate again, evolving into far more terrifying and ferocious forms than before. Here, clean water and food are treasures that adventurers fight for desperately. You can see goblin marauders riding motorcycles, bearded female dwarves, tauren with several heads... The mechanical truth that Charlotte mastered made all technology and magic in the wasteland seem like child's play. From a [broken pistol] to a world-destroying [Star Destroyer Cannon]; From a pair of [rough mechanical arms] to a dragon-slaying [Galaxy Machine God]. Build shelters, build steel fortresses, dragons and star battleships... As the technology tree continues to climb, Sharro's mechanical army begins to sweep across the wasteland. Technological remnants of the old days? A mage who controls the power of nature? A world-destroying dragon that breathes dragon breath? Facing Xia Luo's absolute torrent of steel, he was horribly weak!
