The Level 1 Energy Stone isn't much use to Lu Shinian because he himself possesses 3S Spirit Power. To completely cure the Ancestral Stage phenomenon, he'd need at least a Level 5 Energy Stone.
Not to mention how rare Level 5 Energy Stones are; even Energy Stones with low impurity content are exceedingly scarce.
Even with several mines, he can't find an Energy Stone with only 1% impurity content.
The Energy Stone in front of him, although only Level 1, is precious in a certain sense.
His Ruan Ruan spent a hefty sum to auction it off, just to give it to him.
This feeling of being cared for made Lu Shinian's Adam's apple move slightly, and he uncontrollably pulled her into his embrace.
"So obedient."
Su Ruan snuggled against his chest, her long lashes trembling lightly, "Will this be useful to you?"
She wasn't very sure.
