Earth blood veins

In a spherical underground cave, large patches of yellow soil flash with red light that flows as if blood veins had condensed in the ground. At set intervals the earth blood veins shine and flow like blood capillaries grown into the soil; that motion is what first draws Bai Ning Bing to the red light. After further search, crystal essence is no longer judged highest in quantity here: the blood veins buried in the soil outnumber it. ^{ch. 2076}

Following the veins leads to their source, a delicate black-yellow heart, from which the net-like blood veins spread widely. ^{ch. 2076}
