After climbing the high cliff once more, the first thing Zuo Feng did was destroy the vine rope he had made with his own hands. Only his master and he knew about the cave below, so no clues could be left for outsiders to discover.
He took out two soaked books from his pocket and examined them carefully in the moonlight. From the outside, these books looked no different from the ordinary ones in the village.
Zuo Feng carefully rubbed the surface of the books with his fingers, discovering that the texture was extremely special, much softer and more delicate than ordinary paper. The ink on it didn't seem to be written but rather was integrated with the paper itself.
He believed that given the importance Teng Xiaoyun placed on these items, combined with the special texture and ink that didn't dissolve in water, it was clear that this was not just an ordinary martial skill.
