The origin and relevance of the god’s name Kaos:

Bo Yu was tricked by his mother after traveling through the moon world, so he traveled to Mesopotamian mythology as the original Chaos identity, and therefore had a relationship with the first wife in this world When Tiamat met, he used his own chaotic energy and Tiamat's power to create a race of gods in order to prevent his wife from being bored. However, in order to distinguish his status as a god from a human, he took on the god name"Chaos".

Because he discovered that his wife must be divided into the cause and effect of heaven and earth, he used the power of the beast in his wife and his own chaos to create Tiamat Dragon, and then asked the gods to use Tiamat Dragon to create heaven and earth. The so-called eleven-headed monsters in later generations are actually the product of the unstable fusion of Tiamat Dragon and the power of chaos.

Due to the end of cause and effect, Tiamat needs to fall into a deep sleep in the abyss, while Bo Yu waits for his wife for several days.Years later, I was forcibly awakened by the two world consciousnesses of Gaia and Asaye.

After that, Bo Yu lived countless lives as a human to help the world sublimate, and his wife in these lives lived in the Hall of Valor in the form of a physical heroic spirit.

Finally, he used the seventh singularity to completely eliminate the cause and effect of his wife Tiamat, allowing his wife to live with him as a human being. In return, Uruk was completely restored with miraculous abilities and divided into new branches of the world.
