Although they had obtained the *Nine Yin Nirvana Yang-Absorbing Scripture*, Chen Xuan and his companions could not begin practicing it immediately.

Second, before practicing the scripture, both Chen Xuan and his companions needed to make thorough preparations. Unlike their previous, more casual sessions, this was not something they could simply undertake at any time or place. Success required the right timing, favorable geography, and perfect harmony among the participants—every factor was crucial.
