"What is this? Let me see."

Leng Xuan took from Cheng Guodong's hand what appeared to be a bamboo tube, with nothing unusual about its exterior. It resembled a whittled-down stick with no openings or crevices, and the ends bore no caps or similar objects. However, as soon as Leng Xuan took it, he was immediately struck with a realization. He could feel a faint True Qi emanating from the stick, which carried a chill of Yin. Clearly, the person who had handled this stick was a practitioner of some Evil Cultivation Technique.

Leng Xuan channeled his own True Qi to dissipate the True Qi contained in the stick, and to his surprise, the stick automatically split open in the middle to reveal a rolled-up piece of paper hidden inside.
