Millennium Origin War

In 3033, humans began to explore deep-sea creatures and discovered a nerve repair substance, NerveRepairSubstance, referred to as "N-substance" from deep-sea animals. It can regenerate and repair irreversible nerve cells. You must know that in terrestrial animals, whether humans or animals, damage to nerve cells is irreversible. This is why medical research on the brain has stagnated for hundreds of years. Among deep-sea creatures, a creature similar to an eight-clawed octopus was discovered at that time, with almost unlimited healing capabilities... At this point, the "N Plan" to extend human immortality came into being... Gradually, the true origin of mankind began to be revealed, and mankind, which was fighting for its nation, finally ushered in the thousand-year origin war that has not yet ended in the mythical age—————————— This novel and its characters are purely fictitious.
