章節 413: Enemies On A Narrow Road, Killing the Cao, Liu, and Lu Golden Cores

"This is Earth's Origin Qi!"

Jiang Chengxuan was surprised.

He knew that Earth's Origin Qi was a wisp of mysterious Qi nurtured by the Earth.

The greatest use of this item was that it could be used to refine an Earth-grade Nascent Soul.

As everyone knew, Nascent Souls could be divided into four grades under normal circumstances.

Heaven, Earth, Black, and Yellow.

Other than the legendary Flawless Nascent Soul, this Heaven Nascent Soul was the best. It was also the Nascent Soul with the strongest strength and potential.

In order to refine such a Nascent Soul, two conditions had to be met.

First was to refine the Origin Qi into the condensed Nascent Soul.

Second was to understand one's own Dao path.

Only by combining the two would there be a chance of obtaining the Heaven Nascent Soul.

Below that was the Earth Nascent Soul.
