The location that Lin Mu had just seen was a mountain that was one of the tallest ones in the sinkhole. He had seen it while falling down and it was the tallest object in his view. This plane was far bigger than the one at the Ripple Mist sect and at this point, Lin Mu was sure that it was possibly bigger than the entire Shuang Qian kingdom in size.
"Even Adviser Chu didn't know just how big this place truly was and had barely scratched the surface of it when he explored it. My estimate might not even be close enough." Lin Mu muttered to himself.
"Minor planes like these can be up to ten percent the size of the world they are anchored to." Xukong suddenly spoke.
"Huh? What!? TEN PERCENT!" Lin Mu was shocked to hear that.
"Yes, ten percent. Of course, that is the maximum estimation that I can give you, it is likely to be smaller than that." Xukong replied.
