The second concept rune

The Dao enlightenment Palace cost 100 top-grade spiritual crystals a day. Lu Ming booked the place for two months and spent 6000 top-grade spiritual crystals.

After entering the Dao enlightenment Palace, the Dao of heaven and earth floated. In the end, the intent realms of wind, fire, and Thunder appeared particularly clearly.

Lu Ming took out the path-understanding ancient tree and placed it in front of him. Then, he cast aside the fire and Thunder concepts and focused on comprehending the wind concept.

After a long while, Lu Ming opened his eyes and there was a flash of joy in his eyes.

As expected, the effect of the ancient tree of comprehension could be superimposed with the artistic conception here. It made Lu Ming's comprehension speed faster. It was at least thirty times faster than before.

Thirty times. In other words, one day of Lu Ming's current comprehension was equivalent to one month of his previous comprehension.
