The threat of sea monsters had always existed.
Out of the five behemoths, the giant ape monster and the cockroach sea monster were dead. Only the Dark Ghoul that ranked first, the quasi sea monster that ranked third, and the hellhound that ranked fifth were left.
These sea monsters were extremely intelligent. They knew that the wormhole had been destroyed and that their companions had been killed by man-made mechs. As such, they were keeping a low profile.
They remained hidden while they sent the remaining sea monsters to randomly harass the humans.
On this day, a coastal city was attacked by a sea monster army!
Through satellite positioning, the people discovered that there were as many as fifty sea monsters in this army. It was probably the most powerful sea monster army to date.
The Chinese immediately decided to destroy the sea monster army near the coast of the city. They would not let them escape!
