Chu Zhongtian was making a breakthrough, and the Xuanming Ice Snake had begun cultivating, leaving only Lu Chen bored and idle.
Fortunately, he had set up a barrier that allowed him to see outside, while those outside could not see in.
The highest realm among those guarding the mine was merely at the later stage of Core Formation, so Lu Chen was not worried that anyone would discover his barrier.
Accordingly, Lu Chen took up his Heavenly Inquiry Spear, and used the Silver Spear Like Rain technique to dig through the mine. This spear technique was quiet and discreet, its power dispersed so as not to damage the Spirit Stones.
Although it was slow, it was still better than sitting idly and wasting time.
After all, they would be leaving in less than ten days, so he took the opportunity to mine more Spirit Stones in the remaining time; naturally, the more, the better.
And who knows, he might even find Medium Grade Spirit Stones?
