"The Dragon King Krill can digest most rocks and stones, including iron and copper, but the silver deep in the sea is an exclusion. If they swallow the silver, they will die in no time," Zhang Xiaohou mentioned.
The silver veins in the deep sea went all the way into the Earth's crust. The silver veins had followed the underground rivers like huge dams.
The Dragon King Krill had made holes in the silver veins, but they had to get rid of most of the entire silver veins to make the Underground Rivers accessible to the sea monsters. The larger sea monsters were too massive to swim through the little holes of the silver veins.
