The giant monsters previously had a transparent color like seawater, but then their body turned bright red, and their blue eyes became the darkest black. It seemed like the monsters were still made of liquid, but the density of the liquid was greater than seawater. How steam came out of their bodies showed that their temperature was high, and it could be concluded that the monsters were now formed by hot lava.
Just now, Yu Liang said that he would use the power of Submarine Volcano, and that was why it could be seen that the lava that formed the monsters was not as viscous as the lava that came out of volcanoes on land. Still, it was denser than water, and it was certainly much hotter than water.
