After they left the Cangxing mountain, Jiang Yue and Yu Nianzhen went to a nearby mountain.
The mountain was slightly larger than a big hill but incomparable to the Cangxing mountain.
"This is the location of the first mine." Yu Nianzhen said.
"I know." Jiang Yue said and waved the treasure compass in front of his husband's face.
"Originally, this mine only had low-grade reincarnation stones. However, it hasn't been mined for more than one hundred thousand years and the quality has improved a lot."
"What's the quality?" Yu Nianzhen asked.
"Most are mid-grade reincarnation stones and a few are high-grade."
Hearing this, Yu Nianzhen nodded in satisfaction.
With the reincarnation stones, the Cangxing people would have a higher cultivation speed.
"XiaoYue, can you look at the formation?"
"It's a natural sixth-level formation. We don't have to worry about intruders."
