As they landed on the fifth peak, Mei looked up above here to see the long winding path up ahead. There was no short cut up the mountain and some parts were very narrow. Along the way, Mei could see many holes in the side of the mountain. "Master Bai, what are those holes for?"
"Those are immortal caves. They are for the top ten inner sect disciples. Those caves were created by the first sect master of the Souring Cloud Sect. Each cave has its own spiritual qi gathering array. The strength of the array differs per immortal cave. Each immortal cave is numbered between one and ten. Ten being the lowest rank. Cave number ten's array gatherers less spiritual qi then cave number one. But cave number ten still gatherers two times more spiritual qi than you can get if you were to cultivate outdoors." Bai Hong explained.
