When he saw this stone, Qi Xibei was finally certain that this laboratory was definitely related to Jiang Rongguang!
This stone was a very special material called White Crystal Black Rock.
The energy inside the White Crystal Rocks could allow one to quickly increase their strength.
It could be said that owning this piece of White Crystal Black Rock was equivalent to having a battery that could be charged at any time.
If he was exhausted during a battle, he could use it to quickly recover his strength.
However, White Crystal Rocks were very rare.
Qi Xibei did not expect to see the White Crystal Rock here!
This huge piece of White Crystal Black Rock was placed in a machine with many strings attached to it. These wires were connected to these glass windows.
These countless routes made Qi Xibei's heart sink.
He didn't know what Jiang Rongguang was thinking.
Qi Xibei's eyes darted around as he looked at the glassware beside him.
