Border Infrastructure Decomposes Alien Beasts to Build an Immortal City

Lin Yan traveled through time and became an exile from an abandoned inn in the late Qian Dynasty, and his engineering knowledge was fully reproduced. The barbarian cavalry's machete struck, in his eyes, it was just a disassembled mechanical trajectory - the landing point of the horse's hoof, the offset of the center of gravity, and the flaws in the slash, all disassembled into geometric shapes. One blow, kill. Others hunt exotic beasts and only take the cores, and 90% of the resources are wasted. He is different - the wall made with animal blood is doubled in strength, animal tendons are drawn to make crossbow strings, animal bones are ground into powder to make the best building materials and aggregates, and poison glands are extracted to make poisonous fog for city defense. There is no waste of the whole corpse, this is the correct way to open the strange beast. From the Mortal Bone Workshop to the Dragon Bone Workshop, from the serial flip trap to the Yuan Nucleus Spirit Gathering Formation, he turned an abandoned inn into a war machine that crushed the entire era. When the army of Da Qian's Western Expedition pressed into the territory, he had already built a majestic city with spiritual veins in the wasteland - billions of bones of alien beasts as the foundation, the ninth-level Yuan Core as the energy source, and the third-level state-suppressing mechanism array was activated.
