Chapter 691: Primal Chaos spiritual roots

Feng Jiu's eyes flashed with surprise when she heard this. The worst spiritual root? It seemed that even Teacher Lu did not know that these five-element spiritual roots were the earliest to emerge in immortal cultivation. They are known as primal chaos spiritual roots.

She saw inside the ancient space that the primal chaos spiritual roots were the spiritual roots' outset. It had five attributes: metal, wood, water, fire and earth. But it was not easy to control the five attributes in the body. Cultivating with those five attributes were also more difficult than cultivating with a single attribute. That's why it was called adulterated spiritual roots.
