A fixed pattern of thought was not always a bad thing. It certainly made one's thinking inclined in many cases, but in many others, it simplified thought.
Moreover, because it existed, the human race's thinking appeared stable and consistent.
A person's mind could therefore keep pondering the same proposition for a long time.
Choosing how to think was also part of freedom.
But the Sea God lacked such freedom. Due to innate factors, they had no barriers of perception, yet at the same time, they could not develop mature and complex doctrines.
It was a hurdle they found difficult to cross from birth.
They were philosophers, and they were children.
Naturally, there were no lack of discerning individuals among the Sea God who recognized this. It was they who summarized the shared thoughts of the Sea God—thoughts that would never change no matter what—and created the earliest Sea God inheritance.
But even that was still insufficient to break through the Sea God's innate limitations.
Alas, alas. Once a Sea God wished to form a fixed circuit of thought, it meant abandoning the trait of their Divine Body gathering and dispersing freely, abandoning their communal form of life, and turning themselves into sediment on the seafloor.
