However, there was another species that grasped the martial cultivation method along with humans. They were different than Monstrous Beasts, different than Fierce Beasts, and even more so, different than wild beasts. They had intelligence no weaker than humans as well as noble bloodlines. They also enamored peace.
After they grasped the martial cultivation method, they didn’t do the same as humans and use it for themselves. They started to spread their comprehension to various species, and it shook the overlord position that the humans had. However, the humans did not dare to do anything to them because from what they had heard, their strength was much more powerful than the humans’.
But, such a powerful and noble species went extinct after the Ancient Era, and no longer appeared again. So, people called them “Ancient Organisms”.
Summing it up, the events in that era was filled with mystery, which also caused the people in the present to be very curious about the matters of that era.
