Chapter 728: Mutation
The underground cavern resembled a place of thunderous marsh, a Lightning Marsh hidden beneath the earth.
Below was a knee-deep dark river, while above loomed a thick canopy of thunderclouds.
Qin Sang had never encountered such a bizarre terrain before.
Why would lightning form in a place so deep underground, where sunlight never reached?
He could not find an answer no matter how he pondered.
The few Six-Petaled Butterfly Pansies grew on the far side of the dark river, their roots wedged tightly between cracks in the stone. Aside from that location, Qin Sang also noticed signs of excavation along the riverbank in two other spots.
Judging by the marks, he suspected they had not been digging for spiritual herbs, but rather some type of mineral.
This place was not only home to Six-Petaled Butterfly Pansies, but also rare minerals. It was nothing short of a treasure trove.
The minerals had already fallen into the hands of the witch race brute. He had mined them clean. As for what kind of minerals they were and how valuable, there was no way to verify now.
Six-Petaled Butterfly Pansies, if harvested before full maturity, would wither almost instantly, leaving only a trace of their medicinal energy.
Judging by that man’s actions, if not for this trait, the few mature pansies here would likely have been dug up already.
Perhaps the formation of the thunderclouds was related to that unknown mineral.
