The vast sea, even before doomsday, was also an area hard to be conquered. Too many kinds of creatures were living in the deep sea, and most of them were a total mystery to humans. After doomsday, the sea had become more ferocious and violent. As a result, it was almost impossible for humans to travel by sea. Aquatic mutant beasts were far stronger than the ones on land.
Thankfully, Jiang Liushi possessed the MCV so the Shi Ying Squad could travel by sea. Of course, on their way, they encountered many fierce beasts, including a shiver of sharks - each of them at least twelve meters long. In other words, they were comparable to giant Monosaurus of the dinosaur era. Their steel-like teeth carried such an unbearable force that they could bite off chunks of hard reefs effortlessly.
