The light blue cold spring was releasing a constant stream of formless cold air. However, Lu Sheng could not sense its presence at all.
It was as if the cold spring before him was merely an illusion.
He reached out and attempted to touch it, but felt nothing, which did not surprise him. It was as if he had reached into a body of cold air. The entire cold spring was not a corporeal entity.
He muttered to himself and pulled his hand back. He then closed his eyes and slowly spread his spirit onto the surface of his skin to sense the waves and auras around him.
Soon enough, cold and moist sensations reached his brain through his skin.
"That's it."
Lu Sheng thought about it. Among the minor secret arts which he'd obtained from Ju through dishonest methods, one of them allowed him to store the special energy of some special being around him into his Divine Vein.
