The night passed.
When Su Yang got up, Gu Xiu was already cultivating in the courtyard.
Gu Xiu was sitting cross-legged on the ground with Qi circulating around his body. He put his hands together and held a blood-colored stone.
As the Qi surged, the blood-red stone continued to shrink.
Seeing Su Yang come out, Gu Xiu also stopped cultivating and put away the blood-colored stone with a wave of his hand.
"Old Gu, what is this blood-red stone?" Su Yang asked proactively.
"This thing is called Blood Spirit Stone." Gu Xiu explained," This thing is a subsidiary product of the spirit stone mine. It's contaminated by blood and Qi. Immortal cultivators can't use it, but we martial artists can use it to cultivate."
"This thing is very precious and is something that all martial cultivators in the world must fight for."
Su Yang understood. Then, he washed up and went out. Gu Xiu followed behind him.
