Lin Mu felt the dense spirit qi wafting out of the safe as soon as he removed the door. He looked inside and saw that the safe had two compartments. The upper compartment was the source of the spirit qi. He extended his hand and pulled out a small box that seemed to be leaking the spirit qi.
Lin Mu opened the box and found three spirit stones kept inside it. These spirit stones seemed different from the ones that he already had. These spirit stones seemed to be filled with much more dense spirit qi than the other spirit stones.
"Are these mid-quality spirit stones?" Lin Mu muttered.
"Yes, they are indeed mid-quality spirit stones. But they don't seem to be stable." Xukong replied.
"They're not stable?" Lin Mu questioned.
