Millennium Stone Marrow.
Following the four characters, there was an introduction, "Born from nature's spiritual energy, consuming it can extend one's lifespan and preserve youth forever!"
"What?"
Ling Feng stared in astonishment, his whole body frozen!
"What's wrong with you?"
Zhou Yi didn't know what had happened, seeing him clutching that piece of stone cluelessly, she would have thought he was electrocuted if not for the lack of trembling!
"This is seriously some good stuff!"
Ling Feng regained his composure, gave a strong tug, and pulled the Stonemarrow out from the crack in the rock above his head!
The Stonemarrow, over a meter long and as thick as an adult's arm, felt warm and moist in his hand instead of cold.
Zhou Yi, with a face full of curiosity, asked, "What exactly is this good thing, can you stop being so entranced for a moment?"
"Heh heh!"
Ling Feng chuckled and hurriedly shared the information he had just read with her.
