In the twelve years as Minister of the Ministry of Works of Northern Liao, Situ Lian spent more than half of his time imitating and learning Dongping's advanced technology and experience. However, the more he caught up, the farther the gap was. The technologies that Dongping used in the military and civilian fields, even if the finished products or parts were obtained through those secret spies, were not something that the craftsmen raised by the Ministry of Works of Northern Liao could understand. Telegraph is a typical example. He sacrificed three secret spies and attacked a telegraph station, dismantled some things, and then spent a lot of effort to transport the things back. However, the craftsmen had no choice but to face the coils, metal sheets, and wooden frames... Look

Come on, the telegraph machine does not seem to be a key. Those wind turbines that provide power, wires connecting a telegraph machine, and four-way switches are the key. However, it is not easy to get such things from Dongping. Although the telegraph business of the Communications Bureau is now open to the public, the defense of each node is quite strict. Dongping was originally a country with strong military and strong martial style, and now all institutions, including Yunzhou, like to hire veterans to do things. Those with good minds and good reading and literacy foundations can naturally be competent for various tasks. Those with strong Kongwu will always be in charge of security work in various branches.

Situ Lian has completely given up the technology of telegraph. He started from a technical official who was not worthy of in Northern Liao, and climbed to his current position step by step. He is already sixty-five years old. Fortunately, he laid a solid physical foundation as a stonemason and can still withstand heavy work. Moreover, sometimes he really has to thank Dongping. It is the craftsmen in Dongping. The rise of technology has greatly improved the identities of technical officials in various countries. The upper classes of all countries all hope that they can imitate and produce the craftsmen in the Ye Family Workshop that they already feel that there is no technical content, or at least there is a way to restrain these things, but this is not easy.

The Situ Lian developed the first generation of air defense system in Bei Liao, which was composed of various different equipment, mainly three weapons: crossbows, balloons, and rockets.

Bei Liao understood the principle of Dongping's hot airships, but they did not have the technical force to create airships that could have good control, but there was no problem with manned and unmanned hot air balloons. Manned and unmanned balloons can fill the entire airplane and block the action routes of enemy airships. The rapid lifting and lowering of some small balloons can even attack airships. Considering that airships must conduct precise attacks on the ground and cannot fly too high, tying balloons can at least prevent Dongping's airship army from accurately dropping turbulent bombs on important targets. Among those manned balloons, there are also elite crossbows holding heavy crossbows and trying to shoot airships at close range. Regardless of the accuracy of shooting during the float, it can at least play a role of intimidation.

The Northern Liao Dynasty was able to understand that the crossbow cannons and put them into mass production, which was considered a great achievement. Situ Lian was attracted by the small mount of the crossbow cannons, which was easy to unfold, and could cooperate with high elevation shooting. The most exaggerated anti-aircraft crossbow cannons can be fired vertically, while the gun mount can rotate 360 ​​degrees. The human...the shooting height is naturally not high there. Using a relatively light long-rod shell with a stable tail wing, it can hit a height of about 400 to 500 feet. Now, some of this kind of crossbow cannon has been arranged on the walls of Yanjing, the capital of Northern Liao, and is mainly used to train soldiers and specialize in operating such things. The style of this kind of crossbow cannon with peaceful shooting is really different.

If Ye Tao saw the rockets created by Situ Lian, Ye Tao would probably be amazed. This is an original thing without technical support at all. Although there are similar things in the Ye workshop, the system is completely different. Situ Lian created a twelve-component rocket launcher that can intensively shoot rockets with a little ignition oil warhead to 700 feet high. However, the projectiles are spread too large, and multiple groups of rockets need to be launched together to cover the sky more efficiently. But there is another problem, that is, the rocket's arrow cluster is trigger-type, and once it is not hit, the harm caused by falling is also huge.

After these things were released, the Situ League had already demonstrated three times for the Western Route Army, the Eastern Route Army and the Northern Liao royal family. The results were remarkable and aroused awesome. He, the Shangshu, who had never been very popular, actually received generous rewards. In the imperial edict, he used such a high evaluation of "the morale of the court and the country to boost the morale". The announcement was also very excited about such achievements. Officials at all levels received some rewards. The old craftsmen and craftsmen who were in charge of the development changed their status and were regarded as guests of honor. Before, the Northern Liao Dynasty's bombing, night attacks, etc. were heard in his ears.

, fear is in my heart. Dongping and Xiling are still confronting each other, but they have already taken action against Bei Liao. What if Dongping plays this trick? Originally, dealing with this threat was only a matter of planning, but now, with the Western Route Army losing a total defeat in the first round of battle, it has advanced more than two hundred miles towards Bei Liao and firmly taken root in the front line of Zhongjun Town. The land occupied by Dongping, whether in the people's hearts or basic production, has been completely included in the track of Dongping, and Bei Liao is no longer able to retake it, and the other party is closer to him. Suddenly, defending the sky of Yanjing seemed to have become an extremely important thing.

Situ Lian was even more worried. Although the Ministry of Works had created these things, it was too difficult to produce them in large quantities, with low production capacity, and high cost. Even if you only want to arm Yanjing, it would cost at least one million taels of silver. For Bei Liao, the money can be used to put in other places, which is much more cost-effective than the sky in Yanjing.

The minister of the Ministry of Revenue Zhang Ci, who has similar ideas with the Situ League, is also the Minister of Revenue. Now the economy of Bei Liao has reached a certain level. This time, when the emergency military situation of Biwenxin's troops in the northeast was reached, traces of the crossing of the Dongping army were gradually discovered in the northeast. Combined with the harassment of the Dongping Navy on the coast, it is not difficult to judge that an army with considerable combat effectiveness has reached the rear of the northeast of Bei Liao. Now the central government is mobilizing a large army, and I want to solve the troubles behind the front and Yunzhou before the battle situation between the front and Yunzhou begins, but that's not easy. Bei Liao has mobilized 140,000 troops, most of which are the Eastern Army and the Imperial Guard, but the food, grass and other materials have not been mobilized yet. Bei Liao was originally more than Dongping

There was a shortage of food and grass, and he was a few years behind Dongping in various strategies, and he also strengthened the walls and cleared the fields to destroy his own production. The Ministry of Revenue and the local governments' treasury were quite insufficient. The Western Route Army was willing to allocate part of their combat preparations to deal with the troubles behind it, but the problem was that this long-distance transportation itself was not small. Going back, we had to mobilize grain and grass from other places to return it to the Western Route Army, so that they could fight to the death with the Yunzhou army. This was too unprofitable. So Zhang Ci also firmly stood firmly on the side of opposing the establishment of an air defense system in Yanjing. In his opinion, one million taels of silver, even if it was all used to pay military salaries, would play a greater role in purchasing grain and grass from those rich families who still had grain.

When the two Shangshu, who had a profound impact on the Yanjing air defense plan, submitted memorials to object, and the situation in the court immediately became chaotic. On the other side were the prime ministers, Taifu, General Cheqi and others with huge power in Beijing. After three days of dispute, the king finally decided to allocate 250,000 yuan for the preparation of the air defense plan and expand production, and further develop new devices to reduce production costs. Allocate 650,000 taels of silver as the military expenditure for this Northeast battle. Allocate 200,000 taels of silver to build a second-line fortress group for the Western Route Army, and allocate 450,000 taels of silver to the Eastern Route Army to strengthen combat preparations. This was a happy situation, but the warehouse of the Ministry of Revenue in Beiliao was still emptied.

After making such a large allocation, Zhang Ci only had less than two million taels of silver left in his hand. When Zhang Ci was worried that this time, the dispute in the court made many people see some people who only care about themselves but put the general trend of the Northern Liao Dynasty aside. This time the disagreement finally divided the people who were originally united in the court. Thinking that all kinds of unpleasant waves would arise again, Zhang Ci sighed. However, Situ Lian did not support the air defense plan, which made Zhang Ci very fond. If this plan was passed, the Ministry of Works benefited the most. Even if he did not make any money from it, the influence of the Ministry of Works would greatly increase. But he actually missed such an opportunity.

Zhang Cifu once again calculated the expenses during this period in detail on the case. When he saw where he could save some money, the housekeeper Lao Zhang came up.

"Master, someone is looking for it outside." Lao Zhang was holding a pot of hot tea in his hand. After he filled Zhang Ci, he said, "He is a young young man who is very generous in his actions and gave Xiao Song twenty taels of silver. He was waiting outside, saying that he could solve some small troubles for the adults. Xiao Song couldn't understand where the other party came from, so he asked me to tell him a few words. The young man did look a little from the background and spoke very appropriately. Are you going to see him?"
