When Xue Fanxin had picked up most of the crystals on the ground, Little Lei would punch the wall a few more times. The three of them continued to mine, mine, and mine.
With an efficient mining machine like Little Lei, the mining speed was like the speed of light. In less than an hour, they had already mined more than half the mineral vein.
An hour later, the Mystic Crystal White Tiger returned from the depths of the mineral vein with a green crystal the size of a bird's egg in its mouth. The green crystal was different from the crystals outside. It emitted a strange green light as if it was alive. There were some fine lines on it like human veins, and one could vaguely see something flowing inside.
The Mystic Crystal White Tiger placed the crystal marrow in front of Xue Fanxin. After completing its mission, it acted cute to seek praise. "Awroo…"
Master, I've found the marrow crystal. You must remember my feast.
