In the hours that followed, Zhang Xiaoman used a hearthstone every hour.
Each time, it restored 2 points of energy, and by 10 p.m., his energy value had accumulated to 23 points.
It had to be said that the recovery function of the Nostalgic Hearthstone was incredibly important for him.
After all, Zhang Xiaoman's current methods of attack were rather limited; aside from using skills, he didn't have any effective means of physical harm.
In this regard, Zhang Xiaoman wasn't particularly worried, as following the warrior path clearly wasn't his style. Acting as an elegant mage from a distance was his preferred choice, specializing in survival.
However, as good as the hearthstone was, it had its limitations.
The item description was clear: "Use to recover 2 points of energy," not "Use to gain 2 points of energy."
Thus, once his energy value reached its current maximum, using the Nostalgic Hearthstone again wouldn't increase his energy.
