In the vast stone chamber, more than twenty oviparas sit on the ground, their eyes glued to the blackboard, receiving the baptism of knowledge.
They're all oviparas, but their appearances are somewhat different, revealing that they've undergone some transformations.
Some people have more eyes, not only on the back of their heads, but also on their wrists.
Some have regressed one hand, giving up the flexibility of the five fingers, and instead replaced it with a massive axe blade and a shield protecting their bodies.
Others have directly integrated their left arms with a secondary palate harpoon, extracting their own arm bones and replacing them with the spine of the harpoon, while gripping the pyramid head of the harpoon in a controlling manner. The muzzle of the gun is located on the extended line of the wrist, just a lift of the hand to aim at the target, and a contraction of the muscles to fire the secondary palate.
This integration is quite cool.
