The incessant roaring of the humanoid fish rose up from below. They flew up from the sea with outspread flame wings, towards Zhang Ruochen and his friends.

Even a single humanoid fish was fierce enough, let alone dozens of them.

"I see. This was where the humanoid fish entered the Xixuan Sea."

Zhang Ruochen finally understood what was going on. He finally felt wide awake.

The humanoid fish used to live in the lava deep in the earth's core. They rarely went to the surface, except on special occasions.

The Bloody Trench was incredibly deep, running straight to the earth's bottom and connecting with the lava layer. The humanoid fish was thus able to burst out of the lava layer through the Bloody Trench to the Xixuan Sea.

Meanwhile, another thing came to Zhang Ruochen's mind. Since the Xixuan Sea was less than 2000 meters deep, how come the Bloody Trench was tens of thousands of meters deep?
