Lu Lingfeng guessed that Nanshan Xianluozi was most likely from the Taiyuan royal family, so Wuming Su had already guessed who this person was based on the clues. Pei Xijun said that there is a copy of "The Record of Hermits in Nanshan" at home, which was written by Pei Jian privately. The next day Xijun brought this book, which included 891 hermits, but the people Su Wuming thought were not on the list.
Su Wuming's private entry into the capital was a serious crime, and he wanted to visit Pei Jian for investigation but was stopped by Lu Lingfeng. Lu Lingfeng came to visit Pei Jian with "The Record of Hermits in Nanshan" and asked him if there was anyone who was a colleague of Duke Di, who was familiar with Sha Si and whose surname was Wang. Pei Jian said that he was not in the register. Although he lived in Zhongnan Mountain, he was a current official, and this person was Wang Yuantong.
Wang Yuantong was a long history when his son was the prime minister, and he was later promoted to Fengge Shilang, the power of the prime minister. Later, he was dispatched by Tianhou to be the accused Hecheng, and Wang Yuantong resigned and returned home after feeling humiliated. A year ago, the prince thought of Wang Yuantong, and now he has become the chief bamboo supervisor in charge of bamboo, so he has lived in Zhongnan Mountain for a long time.
Pei Xijun painted a portrait of Helanxue. Lu Lingfeng planned to split up with Su Wuming. He went to find Helanxue, while Su Wuming went to Zhongnan Mountain to find Wang Yuantong. Lu Lingfeng took the little beggar to Xiaoyun Building in Pingkangfang, and asked the little beggar to lead the people out of the building, and asked that He Lanxue had left to go to the ghost city Youqi Building two years ago.
Jin Wuwei was banned from entering the ghost city, and Du Ming was unwilling to send his subordinates to call Lu Lingfeng, so Lu Lingfeng had to come to Chang'an County to find the help of the old catcher. Lu Lingfeng found Lao Jia and the other three, and asked the three of them to go to the ghost town Youqi Building. The three walked to the Youqi Building to confirm that He Lanxue was indeed here, but unless there was gold, they would not pick up guests, and the three felt that the Youqi Building had Weird.
Lu Lingfeng came to the resentment building alone, took out the gold and expressed his desire to see Helanxue, the landlord took Lu Lingfeng to Helanxue's room. Lu Lingfeng wanted to disguise his identity to gain Helanxue's trust, but after a few words, Helanxue saw that he was a housekeeper and wanted to use her to arrest Shas. Helanxue drove Lu Lingfeng away in a fit of anger. Du Ming learned that Lu Lingfeng had found the You Resentment Building and admired his ability. In order to capture Sha Si, Du Ming bought the Ghost Market You Resentment Building and sent someone to stare at Helan Xue for twelve years, and the task of arresting Sha Si was also sent to him by Di Gong back then. Du Ming believed that Shas would definitely pick up Helanxue before the illusion competition, so that people could keep an eye on Helanxue.
Lu Lingfeng dispatched a little beggar to buy Chang'an food for Helanxue in the ghost market Youqilou, hoping to impress Helanxue. Su Wuming brought Cherry to Zhongnan Mountain to look for Wang Yuantong, saying that he heard that Sha Si had sneaked into Chang'an. Su Wuming knew that "Sha Si Biography" was written by Wang Yuantong, and wanted to know other clues that were not recorded in the book, but Wang Yuantong said that he wrote this book for entertainment, and there were no other clues to provide Su Wuming.
The little beggar bought a roasted hump delicacy for Helanxue, but he fainted in the middle of making a human.
