Since the 25th day of the eighth month of the lunar calendar in the fifth year of Zhou Xiande (the eighth year of the Liao Ying calendar), when the fleet composed of three large ships equipped with 500 flintlock pistols sailed away from the newly renovated seaside new port that had just been named Dagu Port by the committee, until the 15th day of the 11th lunar calendar, when the same three large ships successfully returned to Dagu Port, in the past three months, the crossing team basically transported 3,000 flintlock pistols to Binzhou Mansion, which is also on the Bohai Sea, at a frequency of twice a month, in six times. The agreement they made with the Later Zhou court and Chai Rong was completed with good quality.

For this performance of the "Qingyuan" brothers, Chai Rong and most of the civil and military generals in the Later Zhou court were satisfied. Especially when Chai Rong saw that more than one-third of the flintlock pistols sent by the crossing team were old guns that had been used many times, instead of being annoyed by the crossing team using the old guns to fill the number, he felt a little relieved and relaxed in his heart. Because in his opinion, the old guns sent by the crossing team show that the other party attaches great importance to cooperation with the imperial court, and would rather use the old guns he is using to make up for the number agreed with the imperial court, rather than lose faith in the imperial court and disappoint the imperial court because he can't build enough flintlock pistols.

On the other hand, since more than one-third of the flintlock pistols sent by the "Qingyuan" brothers are old guns, it also shows that although their flintlock pistol building capacity is far higher than that of the imperial court ordnance supervisor, it is still limited, and it can only produce about 500 at most a month, and it is impossible to expand the scale of its private soldiers in a short period of time. Moreover, the source of the old guns was almost certainly recovered from the four or five thousand private soldiers under the "Qingyuan" brothers. In this way, it is equivalent to the imperial court in disguised form to achieve the goal of weakening the private soldiers under the "Qingyuan" brothers, which can be called a good result for Chai Rong and the Later Zhou court.

Therefore, while Chai Rong ordered Xu Shaoan to use these 3,000 flintlock muskets to complete the task of expanding the "Shenji Army" as soon as possible, he also issued an order to praise the "Qingyuan" brothers and rewarded them with a large amount of money and cloth, which can be regarded as a kind of reward for their service to the imperial court, as well as a kind of compensation for the manpower, material resources, and financial resources he invested in building these flintlock pistols -- of course, under the current situation, these praises and rewards can only be received by Xu Shao'an.

Although Chai Rong's reward was a lot, it was converted into more than a thousand dollars. But for the crossing team, which is earning thousands of dollars every day, this amount of money is really nothing. Therefore, except for Zhang Weixin, who had to give Chai Rong a thank you on behalf of the team, and Xu Shao'an, who passed the news in the middle, the other traversers didn't pay attention to this matter at all. Seeing that the end of the year is approaching, and the time for Chai Rong's Northern Expedition is getting closer and closer, everyone's minds are on more critical and urgent places, and one of them is the disposal of "Feiyan Hall".

After the enlarged meeting of the committee at the beginning of the eighth month of the lunar calendar in the fifth year of Zhou Xiande (the eighth year of the Liao Ying calendar), the Ministry of Intelligence, at the request and authorization of the committee, seriously investigated, investigated, and investigated the secret spy who had infiltrated the team, the "Feiyantang" suspected of being a secret spy organization under Zhang Yongde, and the relationship between Zhang Yongde and the "Feiyantang". In this way, the operation carried out by the "dark feather" with all its might naturally gained a lot of fruit, and a lot of valuable and effective news was obtained.

Although in a series of investigations, the spies of "Dark Feather" found that the shili of "Feiyan Hall" was shrinking, the spies of "Dark Feather" in the halls of various branches of Youyun Sixteen Prefectures did not relax their monitoring of "Feiyan Hall", but stepped up their work, hoping to get the answers they wanted as soon as possible. To this end, both the committee and the "Dark Feather" headquarters have allocated a sum of money as funds, and have given several ways to obtain medals of honor and medals, in order to stimulate the enthusiasm of these spies, stewards, and even leaders like Liang Ziyue and Zheng Zhiwei, so that they can complete their tasks as soon as possible.

In the face of heavy rewards and huge honors, all the spies and stewards of "Dark Feather" almost went out to set off a huge investigation and investigation work in the Sixteen Prefectures of Youyun and even the entire Liao State and Zhou State, and soon got relatively accurate news on some key issues. The most important of these was that they confirmed that the "Feiyantang" was indeed a secret spy organization established and developed by Zhang Yongde, and that his son-in-law Zhang Fei and his daughter-in-law Zhang Yan had always served as the leaders of the organization, which was also the origin of the name "Feiyantang," and provided Zhang Yongde with all the information and intelligence he needed. ,

However, there are two sides to everything, and everyone will have regrets while achieving results. The investigation of the relationship between "Feiyantang" and Zhang Yongde is clear, but the investigation of the spy who infiltrated the team has made no progress. This powerful spy seemed to have disappeared out of thin air, and no matter how hard the spies of "Dark Feather", especially the spies of the Youzhou Branch, tried to investigate, they could not find any clues of its existence. Whether it was the monitoring and investigation of the various halls of the "Feiyan Hall", or the investigation of Fan Wucheng, who was the most suspected of collaborating with the enemy within the crossing team, and several other traversers who were also suspected, either explicitly or covertly, they did not find enough evidence to prove that the traversers, including Fan Wucheng, had anything to do with the "Feiyan Tang" in private, and at the same time, they did not find out the hidden secret spy.

In the face of such a result, the members of the "Dark Feather" who were originally happy to find evidence that Zhang Yongde was related to the "Feiyan Hall", especially the spies of the "Dark Feather" Youzhou Branch, who regarded the investigation of secret spies as their top task, were a little discouraged, and Liang Ziyue and Zheng Zhiwei also made a review to the committee for this, asking the committee to punish them for their unfavorable actions.

In this regard, the Committee's attitude is quite lenient. While affirming the achievements of the Ministry of Intelligence during this period, they also encouraged and comforted Liang Ziyue, Zheng Zhiwei, and others, who were somewhat discouraged. Of course, the Committee did not do so in favour of the Ministry of Intelligence, but rather as a normal response based on the actual situation.

On the one hand, in the view of the four members (alternate members) of the committee, it is important to find the secret agent who infiltrated the team, but it is by no means the whole purpose and primary purpose of this large-scale investigation and investigation. The main reason why the crossing team carried out such a large-scale investigation and investigation operation this time is to take this opportunity to show the strength of the crossing team in intelligence warfare, and to warn those secret spies who have infiltrated the traverser's side, or are trying to infiltrate the traverser's side, so that they will either retreat in the face of difficulties, or temporarily hibernate, and get rid of the contact and contact with the traverser, so as to establish an invisible isolation belt around all the traversers in the traversing team before the big war comes. In order to ensure that the team can prepare for the battle of Youyun wholeheartedly and without worries, without worrying about their ultimate goal, combat jihua and other confidential information being known to outsiders.

On the other hand, when the committee decided to bring the situation of someone infiltrated by the secret agent within the crossing team to the enlarged meeting of the committee for discussion, it was ready to "scare the snake" and scare the spy away. Because in the committee's view, if the infiltrated traverser has already cooperated with the secret spy, then in the face of the large-scale investigation of "Dark Feather", he will definitely not dare to contact the secret spy again, so as not to expose his treacherous behavior. If the infiltrated time-traveler has not yet cooperated with the secret spy, or has not consciously cooperated with the secret spy, then in the face of this large-scale investigation and investigation by the crossing team, he will definitely be vigilant and have scruples, and in order to show that he has nothing to do with the secret spy, he will inevitably reduce or even cut off his contacts with outsiders. In this way, it is tantamount to indirectly cutting off its contact with outsiders and achieving the purpose of the committee.

Therefore, in the matter of investigating secret agents, the committee showed great tolerance to the Ministry of Intelligence, and only encouraged and praised its achievements, but did not criticize and accuse it of failing to complete its tasks.
