"Good stuff. When I have time, I can get some more."
Lu Yunxiao murmured softly. These Energy Cores were far better than medicinal pills.
No matter how good medicinal pills were, they were still pills. Taking too many was never beneficial.
But Energy Cores were not meant to be consumed. Like Spirit Stones, their energy was incomparably pure and carried no side effects.
Even Lu Yunxiao, who had never taken medicinal pills, found such a treasure quite tempting.
With a soft sigh, Lu Yunxiao put away the system panel and stretched lazily.

Muttering to himself, Lu Yunxiao straightened his clothes, clasped his hands behind his back, and left the inner hall.
Inside the main hall, Gu Xun'er's eyes were closed as she sat quietly to one side.
A crystalline core rested in her jade hand, while dense Dou Qi surged throughout her body.
"Not bad pressure. It seems Xun'er's progress has been quite good."
Lu Yunxiao's eyes lit up, and a faint smile appeared at the corner of his mouth.
Of the high-grade Energy Cores they had obtained earlier, other than those above the Half-Saint level, Lu Yunxiao had divided nearly all the rest equally between Feng Qing'er and Gu Xun'er.

And now that he looked at Gu Xun'er, her progress was no slower.
Judging from how condensed the aura around her was, she had already reached the realm of a Six Revolutions Dou Zun.
Compared with Gu Xun'er at the same point
