This time, Johnnie entered the Thunder Realm to improve his control over the Nine Heavens Tribulation Lightning and deepen his grasp of the Power of the Way.
"Can I take a look at that stone?" Johnnie asked.
Lumi didn't hesitate and handed him the Lightning Core Stone.
The moment it touched his palm, Johnnie felt a strong urge in his body to absorb it.
[Lightning Core Stone: Special item. It was once an ordinary stone, later soaked in the liquid Nine Heavens Tribulation Lightning inside the Thunder Pool. It now contains the power of the Nine Heavens Tribulation Lightning. Absorbing it can improve your control over that power.]
Johnnie resisted the urge to absorb it, gave the Lightning Core Stone back to Lumi, and asked.
"Do stones like this only exist in the Thunder Pool?"
"Yes. My father left this one to me. In the whole Thunder Realm, only he could dive into the depths of the Thunder Pool." Lumi said, looking sadly at the stone in her hand.
