The four Primordial Fierce Insects were born alongside one another in Chaos. They were natural allies, but also each other's natural enemies.
Their nature as living beings forced them to struggle for survival in this Chaos, which was utterly incompatible with their very existence.
To survive while surrounded by those Chaos Demon Gods, they had to band together for warmth.
By joining forces, making up for one another's shortcomings, they managed to escape from the Chaos Demon Gods time and again.
At the same time, their nature as insects made them constantly want to devour one another and grow stronger.
Fortunately, they were not completely mindless. Moreover, there were countless Chaos Creatures in Chaos that could serve as their food.
That was the only reason they retained a trace of reason, avoiding turning on one another first and surviving until Pangu Creates the World.
After undergoing Form Transformation, Golden Cicada had also searched for the whereabouts of the other three Fierce Insects.
Thus, he knew Emperor Fengdu's identity, and he held no grudge against Styx for seizing the body of the Six-Winged Black Mosquito.
The cooperation between the four Primordial Fierce Insects back then had merely been a way for them to band together for warmth.
The cold nature carved into the bones of insects recognized only the cruel law of the strong preying on the weak. There was no such thing as emotion.
The reason Golden Cicada had become what he was now was mainly that, during the process of falling twice and being reborn twice, he had fused with a considerable amount of Primordial World Origin.
This had greatly increased his spirituality and given him abundant emotions.
Aside from Emperor Fengdu's main body, the Blood-Winged Black Mosquito, Golden Cicada had still never found the other two Fierce Insects.
