Lin Cheng took the Secret Manual from a young attendant, running his fingers over its surface. "This is the Fuyue Bear Scripture," he said. "It details the circulation routes and key principles of True Qi for Qi Cultivation Gang and Muscle and Marrow Cleansing. You may only read it here in Weiyuan Hall. Return it to me before you leave. You can come back for it again tomorrow."
"I will remember."
Xu Yang accepted it respectfully. He immediately felt that the Secret Manual's material was unusual—it was soft and delicate to the touch, not like paper. It had to be some kind of Exotic Beast Hide.
Lin Cheng nodded. "Study it carefully. Try to grasp all the key principles before you reach Qi Gathering Perfection, and form your Gang Qi in one go."
Gang Qi was far more potent than True Qi.
