Xu Yan became increasingly convinced that the pool was built upon a Spirit Crystal Mine vein.
Considering this place was the Celestial Tomb, it wasn't surprising that there was a Spirit Crystal Mine here.
At a certain moment, his aura surged, and he achieved a Minor Achievement in the Tongxuan Realm.
"I've achieved a Minor Achievement in the Tongxuan Realm. There's still some distance from a Great Achievement, but even without the aid of the pool's cultivation, breaking through to a Great Achievement won't be far off."
Xu Yan emerged from the pool, and Du Yuying's physical defects had been completely remedied, her aura also growing stronger.
A Great Achievement martial arts master!
Shifting his gaze, he surveyed the tomb chamber. Once the spiritual fog dissipated, it didn't obstruct his vision, and Xu Yan noticed a hollowed-out section on the stone wall behind the pool.
A coffin was placed inside the niche.
