Lack of Spirit Crystals

Under the eight times gravity, Lu Yuan stood still and closed his eyes.

After inscribing the rejuvenation gene, Lu Yuan's spiritual strength was much stronger than before, and naturally, he was much more sensitive.

He could clearly feel the minute changes in his body parts under the powerful gravity.

The blood in his blood vessels flowed, his organs squirmed, and his muscles pulled.

This allowed him to have a more direct and clear understanding of his body.

What Black Steel Force required was the knowledge of the body's strength.

Lu Yuan had already cultivated the Black Steel Force to the second level. In such an environment, he believed that he could cultivate the Black Steel Force to the third level, or even the fourth level, in the shortest time possible.

As time passed, Lu Yuan tried to walk up slowly.

As he walked, Lu Yuan consumed his energy even faster. Even his spiritual power was being consumed rapidly.
