Kapitel 297: The attack of the Dark Moon Empire

Cultivation knew no time. In the blink of an eye, Lu Ming had been in closed-door cultivation for a month.

His physical body had improved the fastest in the past month.

After using three thousand spiritual herbs, Lu Ming's physical body reached the fifth grade.

However, after reaching Tier 5, using some Level 1 and Level 2 spiritual herbs to cultivate would have very poor effects. Only Level 3 spiritual herbs had some effect, and Level 4 spiritual herbs were even better.

However, Lu Ming did not have many level-four spiritual herbs.

Lu Ming still had more than eight thousand spiritual herbs on him. However, he felt that even if he refined all of them, he could not cultivate his body to the sixth grade.

The higher the level of the body, the more energy it required.

Also, after reaching the martial arts Grandmaster realm, one's comprehension of martial arts techniques would be much faster.
