Sha Monk, who was named a golden Arhat, suddenly woke up from his deep sleep on a bloody full moon night. He discovered that there were strange gaps in his memory - some key details about the journey to obtain the scriptures had been erased by a mysterious force. What's even more bizarre is that he found the mark he left in the abandoned cave at the bottom of the Liusha River. The content on it made his hair stand on end: "Don't believe the master... Don't believe the senior brother... If you see this, it means I have failed. Run away!"
