Xun Xu went to Li Miao to report on his work and revealed the news that Si Wencao had been infiltrated by Wei spies.Gu Zheng passed the information to You Xiao, codenamed Chidi, through fixed-point archery. This codename may have been made up by Zhulong to pass on the information.Li Miao immediately promoted Xun Xu to the rank of Lieutenant of the Jing'an Division and ordered him to secretly investigate the Wei spies in Si Wencao and report directly to him.

When Xunxu arrived at Yangping Pass, he witnessed Mi Chong being inspected.He suddenly loudly called Mi Chong to be Master Chen, threw out half a jade ring symbolizing Bai Di's identity, and then fled quickly.Mi Chong smiled bitterly that he fell into this predicament because of Guo Gang's misunderstanding, and was eventually hacked to death in the fight with the Shu army.Chen Gong took the opportunity to escape and hid in the cliff, successfully escaping the search of the Shu army.At this point, Bai Di's identity was exposed, and Chen Gong and Jin Chan escaped from their shells.

At the case meeting, Feng Ying was eager to close the Baidi incident in order to cut off the opportunity for Li Yan's faction to use the issue to their advantage.However, Li Miao revealed the code names of Wei spy Zhulong and Red Emperor that Xun Xu reported to him.Xun Xu did not inform Feng Ying because he was suspicious of him. Li Miao's move put him in a dilemma.At the same time, considering the infiltration of Wei spy Zhulong and Cao Wei's Qingping plan, the conclusion of the Baidi incident was shelved.

Sun Ling was Feng Ying's brother-in-law and was dissatisfied with Xun Xu's behavior.He believed that Feng Ying should learn to cater to Li Yan's invitation.Although Feng Ying felt helpless about Sun Ling's cleverness, he still needed to use him to observe Li Miao's movements.In Jing'an Division, Pei Xu and his colleagues prepared wine and food for Xun Xu to celebrate his return and promotion.However, Xun Xu felt heavy because of the Baidi incident.After Pei Xu reminded him, he learned that Bai Emperor's identity had been made public and everyone knew it.

Ma Dai inspected the items collected from Mi Chong and sent people to hand over these exhibits to Si Wencao.Xun Xu and Pei Xu discussed Chen Gong's fake death in order to replace Mi Chong and break into the Five Immortals Way to track down Zhulong.If Chen Gong is safe and sound, then the person who has access to the secret language engraving is likely to be Zhulong.After investigation, the most suspicious person was Sun Ling, because he personally kept the engravings.Xun Xu felt that he had been monitored since his return.

Feng Ying summoned Xun Xu to meet Qiao Jun, the commander of the Military Technical Department, and explained to him Qingping's plan of Cao Wei to steal the crossbow machine.At the same time, news came that Chen Gong and Mi Chong had entered the country, and Feng Ying arranged for Xun Xu to investigate further.Xun Xu used the excuse not to disturb Feng Ying's official affairs and invited Qiao Jun to talk alone.After going out, he was keenly aware that he was under surveillance.

Yin Ji complained to Gao Tangbing about Xun Xu's performance at the case meeting, believing that he made the muddy waters even more muddy.Gao Tangbing had a close relationship with Xun Xu and did not pay attention to these words.He told Yin Ji that Feng Ying would host a banquet at Ziyan Pavilion to invite them both, and Yin Ji readily agreed.

Xunxu and Qiaojun discussed Qingping's plan and believed that stealing the design drawings was the most likely way.At present, a copy of the drawings is kept in the General Assembly Department of the Military Technology Department in Dingjun Mountain. Xun Xu suggested changing the slogans every day to ensure safety.After bidding farewell to Qiao Jun, Feng Ying met Xun Xu alone.He understood that Xun Xu did not tell him about Gu Zheng's existence because he had doubts about Bai Di's case.However, the situation of Zhuge Liang's faction can no longer delay the case. Only closing the case can relieve the pressure of the failure of the Northern Expedition.

Chen Gong disguised himself as a villager and got into a carriage. The driver recognized the code and confirmed that he was the Five Immortals who came to meet the Wei spies.The two successfully passed the guards at Xiguan. After Chen Gong washed the mud on his face, he immediately assumed the identity of Mi Chong and asked to see Huang Yu, the wine offering sacrifice of the Five Immortals.

At the same time, Li Miao personally came to Yin Ji's home to wait for him.Yinji showed defensiveness and nervousness towards this unexpected Xicao.
