The monsters swimming in the ocean were far more difficult to kill than the monsters on the ground. In addition, there were many of them, so it was impossible to kill them all with cannons alone.
As long as the sea monster hid at the bottom of the sea, the damage would be greatly reduced, and it might not even be able to hit the target.
Fortunately, most of these monsters would expose their bodies to the sea when they advanced and attacked. Otherwise, Tang Zhen might have changed to a new weapon to deal with them.

The entire warship had been surrounded.
Just as the spectators were feeling worried, they suddenly felt a chill as if they were in an ice cave.
Then, with the warship as the center, white ice suddenly appeared and spread in all directions.
