Chapter 508: Chapter 508-framed

Lu Ming's cultivation level began to increase rapidly.

When one reached Lv 2 martial King realm, the amount of spiritual crystals needed to improve one's cultivation would also increase greatly.

Lu Ming's cultivation had only advanced from the early stage of the second level of the martial King realm to the middle stage after refining 50000 pieces of top-grade spiritual crystals.

Fifty thousand Yuan!

When he was at Lv 1 martial King realm, he only needed 30000 spiritual crystals to advance one level. When he reached Lv 2 martial King realm, he needed 50000 spiritual crystals.

Lu Ming did not stop. He kept taking out top-grade spirit crystals.

Upgrade, upgrade, crazy upgrade.

In less than a day, Lu Ming had refined all 180000 pieces of spiritual crystals. His cultivation had also risen to the peak of the second level of the martial King realm.

If he wanted to break through to the third level of the martial King realm, he would need more resources.
