Mag stared at the broken cleaver in his hands, and then stared at that smug fat head fish. He was so taken aback that he asked in his heart, "System, does this stupid fish of yours have an iron head?"
"Please remain calm, Host. This Fat Head Fish lives in Lake Karasana at the extreme north of Norland Continent. The lake is frozen throughout the year, and the oxygen level in the water is extremely low. In order to survive, these fat head fish will use their heads to break the ice every day to obtain oxygen. After tens of thousands of years of evolution, their heads become extremely tough, and thus they are also called Icebreaker Fish. They are a 3rd-tier magic beast." The System gave a brief introduction.
