Soon, following the faint aura left by the yellow-haired Demon King, Yu Qingtan delved 150 miles into the underground.
"Hahaha, it turns out to be a Spirit Stone Mine! Hahaha~"
Yu Qingtan couldn't control his feelings and laughed wildly.
It turned out that this was the temporary cave dwelling where the yellow-haired Demon King practiced, and the cave dwelling was surprisingly built on top of a vein of Spirit Stones.
Spirit Stone Mines do not actively emit spiritual energy, hence they are very difficult to locate, especially those deep underground.
Yu Qingtan released Shen Wanning and shared this great news with her.
"Wanning, I believe this must be the result of your fortuitous luck, hahaha, you truly are a lucky star!"
When the two of them had come out to the wilderness, Yu Qingtan had jokingly said, "With you, a Fortune Cultivation Body with us, we might end up finding some precious heaven-sent materials, just like the Bone Marrow Milk we obtained in the Trial Demon Tower."
