An elliptical-shaped castle had been formed under Lu Zhiyu's manipulations. The beauty of mechanical alchemy was that its products were made up of metallic cells. Even though these products did not contain any intelligence, consciousness, or the ability to think, they did possess some life characteristics.
For example, they had the capabilities of growing, repairing, maturing and modifying themselves. Since Lu Zhiyu had been the one who designed their life template, aside from the insufficient technology to develop a metallic cell brain, which rendered them a bit empty-headed, everything else had grown exactly according to how Lu Zhiyu had wanted!
