章節 158: William, The God Of Fire

Taking the safe, Ning Shi returned to the dormitory.

Because it was personally sent by Hu Changjun, the box was not password-protected. Ning Shi opened the box directly, and there were two stones inside.

One was green and the other was amber.

The surface of the stone had many blood-red stripes that looked like forked branches, like the blood vessels in the human body.

After staring at the stone for a long time, one would feel that the stone was beating, and one's heart would beat faster and faster with the stone.

This magical power was characteristic of an S-level spiritual crystal.

Now that he had two S-level spiritual crystals, Ning Shi was short of A-level spiritual crystals.

He was now at Tier 8 in both his transformation and strength type, and he needed to absorb an A-level spiritual crystal to reach Tier 9 first before he could use an S-level spiritual crystal to upgrade his dual-type abilities to the overlord realm.
