Song Lingfei sat in her room in a meditative pose, with the Demonic Blood Crystal rotating in front of her.
The crystal was sometimes found in Spiritual Lands, the blood of Demonic Beasts, spilled from constant in-fighting could accumulate in small basins, over decades forming a crystal which absorbs more and more of that spilled blood to grow both in size and potency. The fist-sized crystal in front of her took tens of thousands of years to form and saturate to this condition.
Fumes of red smoke-like energy were coming out of the crystal and being absorbed by Song Lingfei, as the veins in her body emitted gentle pulsating glow from time to time.
She has perceived bits and pieces of vague knowledge from their joint meditation with Fen Baihu, which certainly gave results, but they required time for her to process with a human mind and understand.
Her physique was fundamentally that of a human, so she could not access powers that required her to have the body of a Mythical Beast.
