It's not surprising Lin Yi thought this way; after all, the last time a book of Vajra Palm was produced, it was Shaolin's secret technique.
Thus, it is very possible that the opponent would again present a secret technique from the Shaolin Temple this time.
However, when he clearly saw the title on the scroll he took out from his bosom, he couldn't help but be stunned.
Immediately afterwards, his eyes widened instantly, and he exclaimed with a tone full of astonishment:
"Yin Yang Five Elements Dual Cultivation Technique!!"
Following this exclamation, he was taken aback and quickly shut his mouth.
After looking around and realizing that no one was around him, he finally sighed in relief.
After all, he was just a eunuch on the surface.
A eunuch reading such a book is certainly beyond ordinary.
Once sure that no one was paying attention, he hurriedly directed his gaze back to the scroll in his hands.
