Gu Chenfeng and the two women followed the passage for a while.
When they emerged, the view suddenly opened up.
Before them lay an enormous underground cavern.
A circular, pale-yellow curtain of light hung at its dome, like a full moon shining overhead.
The cavern was lush with greenery, like a miniature underground forest.
Dense source qi, almost liquid, lingered among the trees, along with the unusual fragrances of many Heavenly Treasures.
One deep breath left every limb and bone feeling refreshed, lifting the spirits.
Su Wanyue's beautiful eyes swept over their surroundings. At the sight of blue, crystalline stones exposed in the rock walls, radiating dense source qi, her eyes lit up.
"This really is a source crystal vein. Judging by the density and purity of the source qi, this vein is of extraordinary quality."
Shangguan Bingxin's eyes shone as well.
Her keen gaze swept over the intricate energy circulation within the forest, and she clicked her tongue in wonder.
"This source crystal vein and the surrounding terrain have formed a natural spirit-gathering formation.
"The source qi is locked firmly within this space. Over the long years, nature's wondrous workings have even nurtured many spiritual herbs."
The three had already spotted many spiritual herbs growing in the forest, each radiating a strange glow of a different color.
Judging by their age, almost all were over a hundred years old, and there were even rare spiritual herbs two or three hundred years old or more.
Seeing everything before him, Gu Chenfeng could hardly contain his excitement.
The source crystal vein had been confirmed, and rare spiritual herbs covered the ground.
The abundant rewards of this adventure were enough to soothe every hardship.
"Huh? There seems to be something else over there."
Gu Chenfeng looked toward the heart of the forest.
