Chapter 1598
- Since the olden times, sea monsters have lived in the deep sea. In the beginning, they lacked intelligence but with the passage of time, they began to evolve.
- Later on, some demons and sea monsters mated and this expedited the process. They became smarter and built their own home.
- Because of this, the sea monsters commonly known in the Grand Sea were the offsprings of demons and the old sea monsters.
