I Work as a Mercenary in the World of Machine Warfare

Heavy rain poured down on the rusty iron ruins, and Ling Yu dragged the broken "Rust" mecha rolling in the barrage. ——This is the tenth year since he traveled to Blue Star. Once a young man from Earth, he is now a mercenary struggling to survive in the wasteland. In this world torn apart by the "Spirit Skeleton" mecha, the superpowers control the war beasts named after myths, the Holy See of the Holy See imposes divine punishment in hymns, and the wasteland's sentient beings only risk their lives for half of the "Source Crystal". Ling Yu knew that his only bargaining chip was his innate ability to drive spirit corpses: The moment his fingertips touched the remains of the mecha, his nerves lit up like a galaxy; When the blood-stained "Soul Crystal" was pressed into the chest, the bones exploded like a dragon's roar! The moment the nameless ancient skeleton opened his eyes in the abyss ruins, the world chess game began to overturn - The "Canghuang Dragon Emperor" of the Long Yan Empire tore through the clouds and burned the city with its dragon breath; The "Eternal Spear" of the Star Ring Federation penetrates the continental shelf, threatening thousands of miles; The Nine-Glory Holy Seat of the Origin Temple lowered its eyes, and the light of divine punishment purified all things... And Ling Yu stood at the highest point of Rust Town, with the surrendered mercenary army at his feet. He stroked the dark corpse crawling out of the tomb of the Forerunner Era and chuckled throughout the battlefield: "The so-called mythical mecha..." "Nothing but my whetstone!"
