The yin world's origin

With di que's help, the immortal Dao elite warriors of the underworld guarding the primordial land did not discover that Lu Ming was a living being of the Yang realm, allowing him to easily enter the primordial land and obtain a primordial magic art of the primordial land of the underworld.

Lu Ming sped towards the depths of the land of origin.

He had already understood that the yin world's origin was very similar to the Yang world's origin. They were also divided into three layers.

The 1st to 3rd tribulations were on the first level of the surface.

The 4th to 6th tribulations were on the 2nd level, while the 7th to 9th tribulations were on the 3rd level.

With Lu Ming's current cultivation, he could go to the third level directly.

The third level's Qi of origin would be denser and more in quantity, and it would be faster to cultivate.
