If he continued to maintain this state, by the time he returned to Ice Wind Forest, he should still be able to retain 20% of his spiritual energy.
Aside from the lack of spiritual energy in the air of Nanxun, it seemed that there were no other significant effects on him.
Perhaps the more detrimental effects would only occur once his spiritual energy was completely exhausted and depleted.

Outside of Nanxun, inside the Spirit Boat.
Chen Dengming slightly tilted his head upwards.
A ghost-like silhouette, radiating a subtle spiritual light, slowly rose in a floating manner, gently turning her delicate body towards Chen Dengming. His nose touched her small and exquisite nose, and her mouth opened slightly.
Instantaneously, a wisp of Yang energy streamed out from Chen Dengming's mouth and nostrils and was drawn into Xu Wei's.
Her pretty face suddenly looked slightly flushed, and her spiritual light became noticeably brighter.
