Having learned of a new trait of the Rock Biter Termites, Lin Mu reckoned he should take advantage of their opportunity.

'Since they only eat the rocks and leave out the metal ores, this is basically a chance to get plenty of materials.' Lin Mu thought and spread out his Immortal sense in a wide area.

He quickly found all the caves that were being used as dumping grounds and discovered that there were more than just Metal ores there.

'Even gemstones and few other cultivation materials are mixed in…' Lin Mu was surprised.

At first, he wondered why the Rock Biter Termites hadn't consumed them. But a quick check of the documentation about them showed that their bodies simply could not digest those materials. All they could consume was the rocks and rocks only.

It was a strange phenomenon that balanced their power as compared to their population. While they could reproduce fast, their overall power was low due to this.

'This might be why the ecosystem here is still balanced.' Lin Mu thought and quickly got to collecting the rest of the 'junk'.

It took him thirty minutes to gather most of the, despite moving at his full speed.

'That was a lot…' Lin Mu glanced at the literal hills worth of metal ores and other materials that had now been piled up in the ring.

"I guess this gives me an excuse to practice refinement.

" He chuckled.

Done with gathering all this, Lin Mu went to do the task he had actually come here for.

He quickly killed a few Soldier Rock Biter Termites as well as Workers and stored their corpses in the ring. With that done, he was now free to leave.

~shua~

Lin Mu appeared on top of the mountain where Little Shrubby was waiting.

"Did you get the termites?

" Little Shrubby inquired.

"I got way more than just that.

" Lin Mu said before telling Little Shrubby about the 'junk' stash.

"That's a nice bonus.

" Little Shrubby replied.

Lin Mu hadn't thought that taking a break here would yield in something good like this. Not only did he get a good meal, he also made a small fortune just from taking trash.

"One man's trash, no… One bug's trash is another man's treasure.

" Lin Mu said before getting onto Little Shrubby's back.

~WHOOSH~

The two turned into a blur in the night sky, while the Rock Biter Termites were none the wiser about the robbery, murder, and kidnapping that had happened right under their antennas.

The man and beast flew nonstop and about five days passed by before they could see their next destination.

"Damn, that's large.

" Lin Mu said as he gazed at the menacingly tall wall that shrouded the horizon and rose up into the sky.

"We haven't even reached there and we can still see it…

" he muttered.

"We're about two days away right?

" Little Shrubby asked.

"Yeah… and we can still see it. Hard to tell just how tall the wall is.

" Lin Mu replied.

This might have easily been the tallest natural object he had seen so far in a world. The only other thing that could compare to this would be the pillars in Xukong's domain, which were made out of none other than his threads. In the void, it was impossible to even estimate just how tall and long those pillars were.

But the Great Meteorite Wall easily came in second.

"Hmm… The Mountains here are getting shorter.

" Lin Mu noticed as he looked around.

The two continued further and saw that the closer they got to the Great Meteorite wall, the shorter the mountains got. And a day later, all the mountains had become small hills while the Great Meteorite wall only got bigger.

It was the afternoon, and Lin Mu could see the wall clearly now.

The wall was made out of the asteroids that floated around the Rust Sky world and had the same Rusty Red color as them. Now that Lin Mu could observe the wall closely, he noticed that the wall wasn't exactly uniform.

It not only varied in height, its shape wasn't straight either. It curved in some places, while it dipped and rose in some areas.

Another unique thing about the wall was the striations and segmentation that could be seen on it.

"The Meteors fell here and got compressed over time due to the gravity… but even with the compression, the different layers formed due to the meteorites can still be made out.

" Lin Mu observed.

Looking at the barren land a kilometer ahead of him, Lin Mu also figured out where the Gravity started to increase.

The change was abrupt, as the normal area was green and had plenty of plants growing on it. Whereas, the area influenced by the higher gravity was barren. It seemed like no plants grew here and neither did any beasts dare to enter.

If any mortal were to look at this place, they would certainly feel terrified.

It would seem the same as a dreaded forbidden area to them. Which in reality it was.

"Do we go in?

" Little Shrubby asked.

"No… we'll observe for a bit first.

" Lin Mu said.

"And also test out some things.

" He added before getting down from the beast's back.

He picked up a rock from the ground and hurled it towards the wall.

~BOOM~

The rock accelerated at a great speed and created a sonic boom, before entering the gravity affected area.

Originally it was moving in an upward trajectory, but as soon as it entered the high gravity area, it started to descend. And unlike the uniform arc of a falling object, the descent was rather abrupt.

With every meter that it moved ahead, it descended by two meters. And not even a hundred meters into the gravity affected area, the rock had already fallen to the ground and crumbled into dust!

Lin Mu roughly calculated in his mind and analyzed that the increase in gravity was higher than he thought.
