Five days had passed since Lin Mu had stepped on to the World Fragment and he had finally gotten close to the location from where the strange energy waves were coming from.
"Now that's deep… does this go all the way to the center of this fragment?" Lin Mu couldn't help but say as he stared into the bottomless abyss that was located in the frozen caps.
"This might have been a trench in the oceanic world. Possibly the deepest one. Some trenches can go far deeper than the ocean bed and many even go directly into the mantel of the planet.
The depths of the trenches are filled with magma and fuming gases directly spewed from the heart of the planet." Xukong explained.
"I see… though it has certainly cooled down considerably." Lin Mu said.
"We have no idea how long this world has been like this. We already saw a smaller fragment of the oceanic world when you left the fragment of the sacred ground with Jing Luo.
