All this was not something that a Half-Ancestor could detect; it was a secret discovered by the Ancestral Gods, a truth they had deduced and restored.

The Demon Ape Tribe, Scorpion Clan, The Giant Clan, Angel Tribe, and so on were all experimental subjects, created through the modification of humans as the maternal basis; the code of life could be inherited, and from then on, many unusual races appeared in this world.
The hidden hand behind all this secretly observed everything, desiring to obtain the strongest lifeform, and everything was merely for their own sake.
Because they wanted to breakthrough, to make their entire race even more powerful.
