The moment this term popped into Yu Liang's mind, everything suddenly became clear.
He'd previously thought that these tumor-like protuberances were quite different from the "lights" of his past world view; these protuberances possessed a special biological vitality, not the result of a cold mechanical creation, but rather a product of certain biochemical reactions.

The presence of these tumor-like protuberances served a dual purpose: they provide a light source for the incubation room and a portable light source for the man born from an egg.
Yu Liang looked at the ring of protruding bone joints on his wrist, like a toolbox pre-filled with the "tools" obtained by the egg-born man.
