Upon returning to a safe environment, a surge of intense fatigue washed over Spirit.
The consecutive high-intensity battles and the significant loss of Essence Blood had left Spirit in a poor state, and even leveling up did not dispel the exhaustion.
He needed a thorough rest.
"Thud."
Spirit collapsed onto the bed, and after taking some restorative artifacts, he eased himself into sleep and quickly fell into a deep slumber.
...
He slept for a full two days and nights.
With Spirit's current level of life evolution, what he called sleep wasn't a typical deep sleep devoid of perception of the outer world, but a state that maximized the recovery of bodily fatigue.
"Refreshing!"
Spirit stretched lazily after a good sleep, feeling rejuvenated and clear-headed.
Although his Golden Embryo Origin and Essence Blood were far from fully restored, at least his mental fatigue had significantly dissipated.
