Lin Wu gazed at Feng's core and was amazed.
"This is certainly something else." Lin Wu muttered to himself.
The core was unlike anything that was recorded in the many books and documents he had gathered. Lin Wu tried to probe the core directly but found it difficult to. It was as if his spirit sense got deflected every time it got close to the core.
'Is it defending itself?' Lin Wu wondered. 'No, that can't be. He's in an unconscious state right now and besides, a core shouldn't be able to stop me from probing it.' He reckoned.
After thinking for a few seconds and watching the core, an idea came to him.
"Is this a passive effect?" Lin Wu observed it for a bit more and realized why his spirit sense got deflected.
It was because of the flow of spirit Qi around the core. It was like the water current of a river. While it may seem like a river flowing in a single direction, the undercurrent might take several winding routes which were seemingly invisible.
