Traversing The World Fragment

Lin Mu could feel the gravity getting stronger the closer he got to the world fragment. And by the time he reached the very surface, he was surprised to find out the gravity was far greater than he had thought.

"It's nearly double the gravity of Xiaofan world?" Lin Mu muttered in surprise and confusion.

From the concepts he had learned from senior Xukong, he knew that the greater the mass of an object, the greater the gravity it could produce. But as far as he knew from observing, the world fragment was merely a third of the Xiaofan world's entire size.

Thus, it didn't make sense that the gravity of the world fragment was nearly double.

Xukong heard Lin Mu's confusion and spoke, "the density of objects can also affect gravity. Something can have smaller volume but still be great in mass. Just like how gold is heavier than iron." 

Lin Mu understood upon hearing it, but it only made him marvel that much at the world fragment.
