Although the identity problem has now been resolved, Zhang Yan and her subordinates dare not be careless at all. In the face of the police and the "Chengguan Team" who stepped up their patrols, as well as the all-pervasive "Dark Feather Hall", even if they were anxious, they could only temporarily hibernate and patiently wait for the opportunity - after all, although Chai Rong was seriously ill now, it was not the situation that he would soon travel to the west, and the "Feiyan Hall" still had enough time to complete the task assigned by Zhang Yongde.

In this regard, Zhang Yan has a clear understanding. On the one hand, she sent someone back to Kaifeng to send a letter to her brother and father-in-law, explaining in detail the situation on the side of the Beiping Army, and asking her father-in-law and brother to send some more experienced and calm people to help her. Moreover, because of the experience of going north this time, Zhang Yan repeatedly emphasized in her letter to her father-in-law and brother that the newly sent people must be cautious and steady in their words and actions, and must not do anything inconsistent with the identity of the cover before seeing themselves, so as not to be discovered by the people of the "Dark Feather Hall". The "Feiyan Hall" can no longer afford to lose more manpower - after all, the people who can be sent to the Beiping Army are the capable spies in the hall.

On the other hand, Zhang Yan asked the dozen or so subordinates who followed her to calm down. Before the limelight of the Beiping Army's arrest of them has completely passed, they must not do anything that may reveal their identities. Everyone had to learn to do business with the help of those colleagues who had business experience, and they had to convince outsiders that they were a group of businessmen from the south who had come to Luxian to open up trade routes and establish a base for their own owners. For this, Zhang Yan's subordinates are naturally unconditionally obedient. After all, along the way, the strength of the "Dark Feather Hall" of the Beiping Army is there. If it weren't for the head hall master Hong Fu Qitian, who took them out of danger in time, and before the Yamen of the Beiping Army and the whole city of the "Dark Feather Hall" Dasuo were arrested, he found a foothold and a shelter for himself and everyone in Lu County, I am afraid that now I have become a prisoner of the Beiping Army like those colleagues who have been arrested one after another.

Although Zhang Yan led his subordinates to lie dormant in Lu County, it was difficult for the "Dark Feather Hall" to discover his whereabouts for a while, so that Liang Ziyue's plan to capture him quickly and let the general leader of his biggest opponent slip away from under his nose could not be realized in a short time, so that he was always depressed for a period of time after that. But for the entire Beiping Army, the capture of Zhang Yan and his subordinates is not the only thing that needs to be paid attention to now. At the beginning of the twelfth lunar month of the seventh year of Xiande, the attention of the "Qingyuan" brothers was mainly focused on the first ignition and operation ceremony of the steam engine that was about to be held on the eighth day of the twelfth lunar month.

It is said that it is the first ignition operation, but in fact, the steam engine used as an experimental object has been in trial operation for nearly two months before this, and everything is normal, basically reaching the performance indicators set by the Ministry of Science and Technology's Mechanical Power Department when it was originally designed. The so-called first ignition operation on the eighth day of the twelfth month of the lunar calendar is actually a relatively formal ceremony and a walk form at the request of the Ministry of Science and Technology, especially the brothers of the Department of Mechanical Power, to commemorate this milestone in this time and space, this era, and to give these people who have been working behind the scenes in obscurity because of the nature of their work and the need for confidentiality. However, the brothers of the Machinery and Power Department of the Ministry of Science and Technology, who have made outstanding contributions to the development and growth of the crossing team, have an opportunity and stage to accept praise, accept praise, show themselves, and show their achievements -- just as in the past, they opened new weapons Shiyan exhibitions for the brothers of the Weapons and Equipment Division, and opened new materials and new product exhibitions for the Materials Division and the Chemical Industry Division. As for the Ministry of Military Affairs, the Ministry of Administration, the Ministry of Commerce and Trade, the Ministry of Agriculture and other departments, because they have always been active in the foreground, their achievements and achievements are all on the surface, and the victories in battles, the governance of cities, the achievements of each business performance, and the harvest of food every year have long been seen and remembered by the brothers, and there is no need to express them through such ritual activities. …,

On the eighth day of the lunar month of the seventh year of Xiande (December 28, 960), except for the newly appointed chief military officer Wang Feng of Taiyuan Prefecture and Xin Feiyu, chief military officer of Yanmen Prefecture, Yang Xin, chief military officer of Lingxian Mansion and Song Feiyang, prefect of Lingxian Mansion, and Zheng Zhiwei who was far away in Chenqiaoyi, including the brothers of the Ministry of Science and Technology who had been busy building the Taiyuan production base, all the other traversers rushed to the special laboratory of the Mechanical Power Division located in the southern area of "Liangyuan", ready to participate in the first ignition and operation ceremony of the steam engine.

In the morning, just as the brothers who participated in the ceremony were pointing and whispering around the huge boiler, sturdy cylinder, stout connecting rod and flywheel of the experimental steam engine, He Qiang and Fang Guoqiang, the backbone members of the Machinery and Power Department of the Ministry of Science and Technology and the main developers of the experimental steam engine, as well as Zhou Lei and Huang Shan, who had provided a lot of help in the development of the steam engine, walked into the spacious laboratory together, accompanied by the four members of the committee. Although the eldest brother Li Junwu also spent a lot of energy and put forward a lot of useful suggestions for the development of the steam engine, at this moment, he still showed the demeanor of the eldest brother, left the honor and praise to the brothers, and was willing to be their backing and foil.

As He Qiang, Fang Guoqiang and others appeared in everyone's sight, they immediately caused a burst of warm applause, cheers and praise. The brothers were as enthusiastic about them as they were for the military brothers who had won a big battle, or the trade brothers who had made huge profits for their team. Such a scene made He Qiang and Fang Guoqiang, who have always worked in obscurity, spent most of their time in the special laboratories of the Mechanical Power Division in the southern area of "Liangyuan", and had not even entered Beiping City a few times. The two of them hugged their fists and thanked the brothers, and on the other hand, they did not forget to pull Zhou Lei, Huang Shan, and the eldest brother Li Junwu and other brothers who contributed a lot to the development of steam engines to their side, and enjoyed these applause, cheers and praise with themselves.

After the applause and cheers that lasted for a period of time weakened slightly, Zhang Weixin stepped forward in a timely manner, signaled everyone to be quiet, and asked He Qiang, on behalf of the Machinery and Power Division, to introduce the development process of the steam engine and the relevant performance of the experimental steam engine to the brothers present.

Such a request can only be regarded as a piece of cake for people like Xu Shaoan and Qian Yuanshan, who often win battles and make reports, business people like Fan Wucheng and Zhao Dawei, who are very eloquent themselves, or Jishu talents like Zhou Lei, who are cheerful and eloquent, and there is no difficulty in dealing with them - many times, if it is not for the host of the meeting or ceremony, they can talk for hours. can be put on He Qiang and Fang Guoqiang, two pure jishu talents who usually speak little and only know how to work hard, it will be a little difficult for them.

But the enthusiasm of the brothers can not be disappointed,In the attempt to pull the eldest brother Li Junwu、Second brother Zhou Lei out"Top bar"After the failure,He Qiang had to take two steps forward,After thanking a group of brothers and a number of TV,Begin to tell you about the development process of the steam engine、Difficulties encountered、Ways to overcome difficulties、The principle of the steam engine、The performance parameters of this experimental steam engine,And so on。

For He Qiang, who is not good at words, it took a lot of effort to talk about the previous development process, what difficulties he encountered, and how to overcome these difficulties, so that he actually began to sweat on his head in the winter. It wasn't until he began to introduce the principles of the steam engine and other relatively professional content within the scope of his work that He Qiang's originally nervous and cramped mood gradually relaxed. I stopped stumbling when I spoke, my nerves were no longer tense, my speech was smoother, and I was more confident and confident in speaking. Later, when it came to the performance indicators and specifications of this experimental steam engine, as the main developer and producer of this epoch-making equipment in this time and space and this era, He Qiang also became energetic, not only speaking like a river, but also cooperating with his actions and expressions very well, and the introduction of his work results was more accurate and detailed. The brothers who had little interest in physics listened to it with relish, and they couldn't wait to start the machine right away to see if it was as powerful as the twenty-brother (brother) said. …,

Perhaps because he saw the expectations of the brothers, or because he wanted to show everyone the results of his work and that of Fang Guoqiang and others as soon as possible, He Qiang ended his speech in time and asked his eldest brother Li Junwu to light the boiler.

Although for He Qiang, who is not proficient in human affairs, he asked Li Junwu to light the fire only because the other party is the eldest brother of himself and all his brothers, and he is the director of the Ministry of Science and Technology and his direct leader, and there are no other complicated ideas in it. However, Li Junwu, who is old-fashioned and dignified, mature and calm, cannot but take into account the feelings of other committee members. Therefore, He Qiang's voice fell, and Li Junwu had already said that at such a historical moment, how could he dare to be beautiful, and the four members of the committee and the four brothers who participated in the development of this experimental steam engine should make a stove and light it together. Subsequently, before He Qiang could react, Li Junwu had already ordered someone to increase the number of torches used for ignition from one to eight, and suggested that eight people line up in a fan-faced formation and complete the ignition ceremony side by side.

Li Junwu's suggestion was naturally unanimously approved by all the brothers. The eight brothers stood up in turn, and at the same time put eight torches into the feed port of the steam engine boiler to complete the ignition ceremony in the sound of the "ignition" password shouted by Wang Kunjun and He Qiang, who were in the center.

Of course, this ignition ceremony is just a formality, and its symbolism is far greater than the actual effect. Since the mechanical power department built this steam engine in the middle of October of the lunar calendar and began trial operation, the fire in the boiler has not been extinguished. Because of this, after putting the torch into the boiler inlet, He Qiang was able to immediately step forward and pull the steam transfer valve, so that the high-pressure steam that had been directly transmitted outside the laboratory in order to cooperate with the ignition ceremony could flow back to the steam engine cylinder. As the pistons in the cylinders moved left and right under the impetus of the hot steam, the huge flywheel of the steam engine began to spin under the driving force of the connecting rods.

Listening to the huge roar of the steam engine and watching the flywheel spinning faster and faster, the people present once again gave warm applause, cheers, and praise to He Qiang and Fang Guoqiang, who had spent four years before and after developing this machine, especially in the past two years.

Listening to the applause, cheers, and praise of the brothers, and looking at the steam engine that they had worked hard for four years to finally achieve positive results, He Qiang and Fang Guoqiang were even more excited and burst into tears, stretched out their hands to each other, and held them tightly together.
