"Open." Ji Ning was standing at the peak of a mountain, staring down at the vast wilderness before him. He waved his finger, and with a boom an invisible surge of pressure slammed down upon the wilderness, causing an enormous indentation to appear on the ground. The indentation was nine hundred meters deep! Ning then reached out with his right hand, causing a small little black gourd to appear. He pulled out the stopper, causing a stream of deep blue water to flow out from the gourd. The stream of water grew in size as it flew out until it became many meters thick, almost like a watery dragon as it soared out to fill the indentation.
Whoooosh. The liquid continuously poured out, quickly filling nearly half of the indentation. This was the frozen ninesong pith Ning had just recently acquired.
"Go ahead, children." Ning smiled as the six Northbow swords on his back instantly flew out of the sheath, each one of them manifesting a child.
