At first, Shen Luo was a bit puzzled, but after a brief consideration, he understood.
The books in this hall were mostly open to all inner and outer sect disciples. They were mostly basic techniques. It was unlikely that the sect's true heritage of important classics would be kept here.
This was actually no different than the practice of the Spring and Autumn Pavilion. The Sect's foundational techniques were mostly passed down orally between the masters and disciples and kept secret. The Pure Yang Sword Technique was handled this way.
After a brief rest, Shen Luo picked out a few basic cultivation methods from the pile of ancient books, as well as those about Spiritual Medicine and Artifacts Refining, and stored them in the Seven Star Pen.
Then, he collected the remaining unfinished books. Only then did he stretch out and planned to leave through the hole in the wall.
