Instantly, sword qi filled the cave.
The insects came like a tide, but before they could get close to Xu Ning, they were slashed into pieces by the sword qi.
In just a few seconds, hundreds of blade-mouthed insects were completely wiped out by Xu Ning.
Xu Ning looked at the fluorescent stone on the ground and picked it up one by one, then absorbed its energy.
'Almost 350 units of energy!'
Xu Ning absorbed all the fluorescent stones in the body of those insects. He had gained a lot.
'I just entered the mystic realm, but I have already gained such a rich harvest. If I continue to explore this mystic realm more, there will definitely be more energy to absorb.'
Xu Ning continued to explore.
But this time Xu Ning was more cautious.
Although that group consisting of 300 blade-mouthed insects were only in the middle level of the mortal realm, there were a lot of them.
