Autumn and winter fields are already waiting in Huludao.

It took a lot of effort to transport this batch of artillery. For this reason, the Railway Administration specially allocated a train of rail cars, and the general of the Central War Zone, Huang Shang, selected a group of soldiers to escort the car. These soldiers were not ordinary soldiers, at least a sentry leader. The Ministry of State Security was even more like a great enemy. In addition to Tian Zhen personally taking charge of the rail cars, he even threw many nails along the way the rail cars passed.

Of course, these people had no idea what kind of mission they were carrying out. In the entire itinerary, except Qiu Dongye and his masters, only Tian Kang, Tian Zhen and Huang Hao were left. The only thing others could know was that they were carrying out an extremely important military mission.

Compared with steam engines, Ming Dynasty had no idea how much confidentiality of gunpowder and artillery was higher than that of gunpowder. To put it bluntly, steam engines were to be used in workshops, factories and mines on a large scale. Wherever such a big guy was placed, he was not a blind man, and anyone could see him.

Of course, it is not necessarily possible to learn it if you can see it. For such a precise machine, if there is a problem with one bolt, the whole machine will fall into trunks. Most of the parts of today's steam engines are handmade by masters of the Construction Bureau. Like some reinforced bolts, they look simple, but in fact they are quite expensive. A mature craftsman may not be able to polish a bolt a day. For things like rubber for sealing, only those who know the manufacturing method are the workshops under the Daming Tian Industrial Bureau, and the raw materials for making things like Jiao come from overseas.

All of this has caused the steam engine produced by Tiangong Department to be extremely expensive, just like the merchant who dug a canal, which cost tens of thousands of taels of silver just by renting it. It is because Tiangong Department has to conduct actual inspections of the steam engine to get the fee.

To put it bluntly, even if Qiren saw the steam engine, they would not be able to learn it. Even if they put a real machine in front of them, they would not be able to prevent it.

The cannons and gunpowder are different. Like fire, the formula is actually extremely simple. The key point is its purification and improving its power. If the formula is obtained, there are always ways to slowly increase its power through repeated trial and error experiments. This is how the masters of the City of Power did it. The craftsmanship of the cannons are not too difficult. For example, in some later eras, ordinary people could even use a whole tree pole to hollow out some earthen cannons, which could still be used. Although the lethality is not great, it is still very good to hear the sound and scare people.

The Ming Dynasty court hoped that gunpowder and artillery could play an unexpected role beyond the enemy's expectations in the Ming and Qi war, giving the opponent the greatest double damage to the body and mind.

So when the steam engine had already appeared in front of the world in a dignified manner, gunpowder and artillery were still in the state of the highest level of confidentiality in the Ming Dynasty.

After Qiu Dongye and his master arrived in Huludao, they moved directly into the dock, where there were warships that were being overhauled or were still under construction. They needed to have a basic understanding of the warships first, and then they could consider loading the cannons onto the ship.

This is not a matter of installing these artillery at any location on the ship. They have to consider too many things, first of all, the counterweight issue. One cannon is one or two thousand kilograms, and the main cannon weighs more than five thousand kilograms. It would be better if these big guys were mounted on slow-speed human-powered warships, but the warships driven by soup steamers are extremely fast. They don’t want the warship to make a sharp turn, and they directly overturned into the sea because of their own gravity problems. Secondly, it is the problem of killing. People from the Weapon Research Institute study a new weapon. The first thing to consider is how to be light and easy to use. How can the artillery be laid on the warship to achieve the best killing effect? ​​Of course, we have to discuss with the ship. There are too many such problems. Although the artillery has been shipped to Huludao, it is still far from the day of actually boarding the ship.

From the first day of Yu Cong and Ning Zeyuan's anti-aircraft counterattack, there would be fierce quarrels coming from a public room specially packed for them in the dock every now and then.

Whether it is Yu Cong or autumn and winter, they are not gentlemen. They are all figures who get up step by step from the lowly muddy soup. Even though they have become high-ranking officials over the years, they have developed some demeanor, but once they close the door and start discussing these pure academic things, the two of them will immediately reveal their true colors.

First, there was a technical debate. Yu Cong wanted to use the ship faster and more conveniently to control the ship, but Qiu Dongye thought about how to exert the maximum power of the artillery. The two of them had the same overall goals, so they were above the branches, but there were many disagreements. At this time, they started to quarrel.

Such a quarrel is naturally the reason why the mother is right. No one can convince anyone.

If there is no technical conclusion, the two officials began to attack personally, wanting to refute the other party from morality and character, and criticize the other party in a perfect way. Of course, the best result is to make poor lyrics and music. A guy with flawed moral character will naturally retreat in shame. Unfortunately, the two people who were poor in the past had a lot of braids in the hands of each other. Therefore, no one can do anything to anyone.

Whenever this is the happiest time of Ning Zeyuan. He doesn't understand the technology very well, so he usually acts as a spectator. Two fourth-rank officials have such a quarrel that they have revealed in their true colors and cannot be seen outside anyway, so he can watch and listen to it with great pleasure.

But then, he could not sit still. After the two fourth-rank officials found that they could not convince each other in words, Ning Zeyuan was also dumbfounded.

They actually started a fight.

When the boss started fighting, the masters under his command were naturally not to be outdone, so the entire public housing became a place for fighting, fighting to the point where the sky and the earth were dark and the sun and the moon were gone. What Ning Zeyuan could do was to escape to avoid the disaster. If both sides had their eyes red, who would recognize who?

In the end, it was Tian Zhen who came to solve the problem. After the Ministry of State Security separated these masters one by one, they were exhausted and sweating. They dared not use force. Any of these people were all treasures of the Ming Dynasty. Although they called themselves craftsmen, they were actually all officials. None of the guys fighting were lower than the sixth rank. They could not use the means of dealing with enemies or rascals to deal with them.

After the fight, the anger broke out, but the matter still had to be resolved. Both sides still had to sit together and start discussing again. Whenever Ning Zeyuan looked at the bruised and swollen group of people, he couldn't help laughing, but he admired these people from the bottom of his heart. Those who are brave enough to stick to their own ideas are always worthy of admiration.

Ning Zeyuan was not in a hurry. He hoped that the two gangs would find the best way to solve problems while quarreling and fighting. After all, these warships were used by their navy in the end, so the fewer the problems, the better. Of course, it was impossible not to expect problems. The new power system designed by Xu Lai often appeared in problems because it was too precise. These problems were gradually solved one by one in the long-term use later. Even now, there are still a group of people in the Tiangong Administration who have been stationed in the navy, specifically solving or improving the problems that arise in these power systems. And new things like steam engines and artillery will naturally have more and more problems in the long-term use.

The quarrel between the two gangs is only a superficial problem, and it is some big problems. Ning Zeyuan certainly hopes that they can solve the more they can solve. Anyway, the strength of the navy in his hands still maintains a crushing advantage against Qi State, so he doesn't mind that everyone will do better with the new warships.

In the end, he basically no longer appeared in this public room. For more time, he would rather stay in the warehouse where artillery was stored, stroking the cold barrels, and imagine the day when he saw them spewing out their flames.

Compared to Ning Zeyuan's comfort, Tian Kang, who was far away in Yuejing, was a little worried. The countless information gathered together showed that Qin Li, the big fish, slipped away from his hands again. This made Tian Kang extremely angry and made him deeply feel the gap between himself and his former commander Guo Jiuling. If Guo Gong was still there, or Qin Li had now become a prisoner of the Ministry of State Security.

Xie Qiu and Ma Zhaoxu stood in front of Tian Kang, both bowing their heads and silently enduring Tian Kang's anger. Such anger is the most terrifying. The two leaders of the Ministry of State Security who are in charge of this matter are now ashamed.

Xie Qiu used to work in Changyang County, while Ma Zhaoxu was a local snake in Yuejing. Both of them worked step by step from the bottom and had extremely rich practical experience, but this time both of them fell into Qin Li's hands.

"Tell me!" Tian Kang said gritting his teeth.

"After the clues found that Wuliu Shu's small restaurant was completely broken. The owner and waiter of the small restaurant were all dead and died in the small restaurant. We also went down the tunnel inside, but the tunnel connected the sewer pipeline system later built in Yuejing City. It was well connected. It was impossible to determine where it led, and it was impossible to determine whether it was just an escape passage or a nest hidden by the opponent." Ma Chaoxu was dejected.

"In other words, nothing has been found." Tian Kang had a gloomy face.

"Yes." Ma Zhaoxu nodded awkwardly, "Or, we can think of a way from that Zhou Qiu."
