Knights of the Gods

A thousand years later, the earth was occupied by alien creatures called "Zhuo people", and what followed was a life of slavery that lasted for more than three hundred years. Humanity did not give up resistance and secretly developed a new special metal "mechanical spirit" The organs created by the Mechanical Spirit are transplanted into the human body, breaking the fragility of flesh and blood, and possessing extremely high physical fitness. Everyone can become a super human. The Mechanical Spirit metal enables humans to enter a higher civilization in advance. We call it the "Mechanical Spirit Era"
