Fourth Ring?

Lin Wu opened the Beast Servant section and clicked on the location option. This directly took him to their current position on the map.

As of now, the Split thorn horn beetle was the farthest from him and had traveled to over 250 kilometers. Lin Wu could tell that it was heading towards the south western direction but didn't exactly know what existed there.

On the other hand, the Deep Earth Millennium Mole was traveling underground similar to Lin Wu. He was a mole beast and thus had an innate affinity to digging, quite like Lin Wu. But his speed was slower than Lin Wu's digging speed and he was about 190 kilometers away from him in the southern direction.

Even when Lin Wu was using his normal method of digging, he would have been faster than the Deep Earth Millennium Mole. But now with his Drill mode, he was very fast and could cover about two hundred kilometers in that mode.
