The cavern at the bottom of the Lake was dark, without a trace of light, yet the surrounding spiritual energy grew ever denser.
The cave twisted and turned, but it was quite spacious. The flood dragon's massive body could pass freely through its entrance.
Song Wen discovered that the force interfering with his divine sense originated from the dense spiritual energy emanating from the surrounding walls.
He held an Earth-Escape Talisman in one hand and the Nine Calamities Measuring-Heaven Sword in the other. The blood corpse stood beside him as he cautiously followed behind the flood dragon. Yet after advancing dozens of li into the cave, he encountered nothing unusual.
Suddenly.
He noticed a fist-sized crystal embedded in the stone wall to his left.
The crystal was translucent and emitted pure spiritual energy.
Song Wen narrowed his eyes slightly. This crystal was a Mid-Grade Spirit Stone.
He raised his hand and fired a thread of mana, shattering the stone wall around the Spirit Stone.
The Spirit Stone immediately fell from the wall, cutting through the Lake water and landing in Song Wen's hand.
Song Wen examined it for a moment before storing it in his storage ring.
The flood dragon was drawn by the commotion Song Wen had caused. It glanced back and spoke through its thoughts.
"The quality of this kind of stone is too poor. Many nearby caves have them. But the best kind of crystal can only be found deep within this cave."
As soon as it finished speaking, Song Wen discovered two more Superior Spirit Stones. He collected them in the same manner.
As they continued onward, Spirit Stones appeared with increasing frequency, and their quality was not low. Mid-Grade Spirit Stones made up the majority, Superior Spirit Stones were fewer, and no Supreme-grade Spirit Stones
