The runes revolved around the books and then entered the jade slip. After they entered the jade slip, its color changed and it became completely green. The formation array that had lit up soon faded away and everything went to normal.
Jing Wei waved his hand, and the pile of books all went flying back to their respective places. He then picked up the jade slip and took out another jade slip from his spatial treasure. This jade slip was different in color being azure blue.
He tapped the green jade slip with the azure colored jade slip and made it glow again. He then stored the azure one away while passing the green jade slip to Lin Mu.
"I reckon you know how to use a jade slip, at least?" Jing Wei questioned in a teasing tone.
'Tell him yes. You can use it with your spirit sense.' Xukong spoke in Lin Mu's mind.
"Yes, I do know." Lin Mu affirmed.
