Cheng Zijin did encounter trouble, and it was a trouble that could not be solved at all.

This trouble made him feel disheartened. He spent so much effort and effort, but who would have expected that things would be so bad?

So this guy began to slack off, hurting his self-esteem, so he naturally slept with his head covering every day, regardless of day or night.

At this time, Hao Fenglou visited.

The reason why Hao Fenglou visited was not because he had any interest in invention and creation, but because this steam engine was too important to him.

The bizarre changes in the court have already made Hao Fenglou feel a strong sense of oppression. His Royal Highness, the old school, and even some bad intentions of the Jingnan meritorious deeds made Hao Fenglou feel like he was in a turmoil. One victory after another, but if the opponent is not defeated in one day, then there is a day of failure.

And at that time, what else can I rely on? Besides Lang San, I can only rely on.

Hao Fenglou could no longer wait. Not only Hao Fenglou, but also the giants behind him, the students Chen, and many gentry who have gained benefits from it must have the same anxiety as Hao Fenglou.

Therefore, the steam engine must come out. After it comes out, the efficiency here can be increased ten times or a hundred times, and the entire Lang Son and Jiaozhi can become the most solid fortress.

Hao Fenglou stood in front of the couch with his hands behind his back. Cheng Zijin was still sleeping with his head covering. Hao Fenglou sighed and said, "Mr. Cheng should wake up."

Cheng Zijin knew that someone came in. In fact, as a bachelor, he was here every now and then. A servant pushed the door and cleaned it, so he heard the movement in a trance. But he didn't move, just because he didn't care.

When Cheng Zijin heard Hao Fenglou's voice, he was shocked and sat up quickly. Looking at Hao Fenglou, Cheng Zijin was suddenly at a loss.

Hao Fenglou looked at him. He did not blame him. He casually pulled a chair and sat down, saying, "Stop talking. Are you in trouble, what trouble?"

Cheng Zijin quickly got up and put on his clothes, feeling embarrassed. He wanted to pour tea. But he couldn't move. Hao Fenglou was straightforward. He simply stopped twisting and said straightforwardly: "This steam engine replaced horsepower. The students had hope. Although everything was bumpy, it was generally smooth. I had no choice but to wait until the things came out. The students found that the steam engine weighed thousands of pounds. Although it was more powerful than horsepower, it was still far behind when it was really moving. Fortunately, due to iron workshops everywhere, various iron textile machines and carriages were started to make many things ready-made..."

Cheng Zijin talked and told his troubles. He was right. His steam engine "car" was able to progress so smoothly, which was indeed inseparable from Lang Son's accumulation in recent years. Now in Lang Son, the status of blacksmiths has been greatly improved, the level of skills has been greatly improved, and some strange "things" have also begun to appear. This has made Cheng Zijin follow the general direction of Hao Fenglou, and has huge amounts of money to support him. There are countless skilled craftsmen working for him. After several twists and turns, the effect is significant.

The biggest problem he encountered was really shocking to say, that was the simplest problem. The steam engine was huge. With his current skill level, no matter how simplified it, it weighed thousands of pounds. Such a huge weight, even if it was installed with wheels underneath, it could barely move, but it was very difficult, far less than horsepower. Although the horsepower was small, it was light and could move quickly. Moreover, such a huge giant really wanted to control it.

Hao Fenglou was also stunned. He forgot to tell this guy that the train has wheels and rails. It is precisely because of the rails that can reduce friction on the one hand, and at the same time, limit the steam locomotive and grasp its direction.

This is Hao Fenglou's negligence. In fact, as long as the steam engine comes out, it will only last for decades and will always appear. However, Hao Fenglou has real experience and naturally cannot hide it. Hao Fenglou glared at him: "Does Mr. Cheng know the resistance?"

The beginning of this question was the main topic of the two people starting to talk.

Hao Fenglou spoke out some basic common sense from later generations, and finally took a pen and ink, drew the wheel tracks, and finally said: "Mr. Cheng thought about it. If you put the car on the wheel tracks, you don't have to pay attention to its control. You just need to move forward and stop. The wheel track must be smooth enough to fit the wheels in the steamer. In this way, the resistance is greatly reduced. Once the car is activated, it is indeed slow when it starts, but once it develops inertia, it is much easier..."

Cheng Zijin frowned and tried hard to digest Hao Fenglou's words. In fact, in the past two years, due to the improvement of his skills, some scholars began to involve physics. Some scholars even wrote some "strange talks and strange theories", which were all strange and lewd skills. Cheng Zijin was interested in this area and was more knowledgeable. Now he found that Hao Fenglou was talking more thoroughly. He couldn't help but fall into thinking, feeling a little bit of eyebrows, and sat down for a stick of incense. Finally, he grabbed his hair and tore the straps of his hair. So he disguised his hair and ignored Hao Fenglou and rushed out like crazy: "Hurry, hurry up, invite the two masters Liu Xian and Zhang Cong, and..."

The sound is getting farther and farther...

Hao Fenglou smiled bitterly, is your mother considered to be a bridge breaking through the river? I taught you with great sincerity, but you are so good, but you are running away.

Most of these people have strange tempers, and Hao Fenglou could only understand them. He also pointed to the appearance of the steam train. After the appearance, Lang San was afraid that the whole of Lang San would change a lot again.

But... Hao Fenglou couldn't help but shake his head and smile bitterly. The so-called trains at present are probably very vulgar and simple. As for the speed... they are afraid it is terrible. Although the appearance of this thing has crossed the times,... Hao Fenglou shook his head and smiled mockingly.

………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………

A few days later, a letter was sent to Duke Luguo's Mansion.

In front of the sender, Hao Fenglou personally opened it.

The letter was sent by the King of Siam. After Hao Fenglou opened it, it contained duplicate letters in Siam and Chinese.

The content inside was a bit unsightly. The King of Siam was not friendly to Hao Fenglou's "kindness". The person who wrote the letter was actually not the King of Siam, but a small official from Siam. He was afraid that he was just a poor man. He told Hao Fenglou that he had never heard of the Marquis of Haifang. If he wanted to negotiate, he asked the Emperor of Ming to compile a book, and the King of Siam would respond. He also said that Jiaozhi had bought the timber, iron ore, and the silver was severely outflowed in Siam. Jiaozhi should give compensation, otherwise the trade route would be banned...

Hao Fenglou read the letter, but was not annoyed. Instead, he asked the merchant who was sending the letter in the middle and said, "Sir, you see the King of Siam."

The merchant’s name is Chen, with a single name and a Zhu. Chen Zhu shook his head and said, “After submitting the letter from the Marquis, the response was only a prince of Siam. He just sent this letter and ordered the villain to bring it back.”

Hao Fenglou frowned.

Chen Zhu said: "Originally, the villain did have a lot of relationships with the King of Siam, so in the Siam court, he also asked some people to meet the King of Siam. However, they seemed to have some difficulties. They just told the villain that the King of Siam would not meet the villain. They also said that the King of Siam has repeatedly summoned ministers to discuss matters of the Ming Dynasty, and seemed to have some plans."

"Planning, what kind of plot?"

"This is hard to explain." Chen Zhu seemed a little hesitant and finally said: "In fact, if the Ming Dynasty did not conquer Jiaozhi, this Siam would be very obedient to the Ming Dynasty. The King of Siam also had no complaints about the Ming Dynasty. However, since the Ming Dynasty took Jiaozhi and enfeoffed the chieftains, which made Jiaozhi Dading. Many chieftains followed the Duke Lu's mansion to make profits, and people's hearts were very calm. Even ordinary people had their own business. In this country, many nobles had other thoughts. For these people, they would be ministers of the King of Siam and the Ming Dynasty.

The chieftain seems to be no different. Last year, a pro-Ming faction appeared in Siam. The minister Po He was divided into two groups to try to imitate Jiaozhi. He also said that the Siam king came to Langshan and publicly traded with Luguo. This move attracted the support of many Siam people. However, the Siam king Zhaolu Qunying was displeased and killed Po He and began to search for his "remnants". After that, his relationship with the Ming Dynasty became cold. The Siam people were very wary of the Ming Dynasty and even ordered many people not to interact with Jiaozhi without authorization..."

Hao Fenglou also heard of these things. In fact, this is natural. Advanced civilizations encountered backward civilizations. The Ming Dynasty was far superior to Siam in both literature and art and economy. Now Jiaozhi has become a role model again. There are different degrees of voices in many Western vassal states. Those nobles who are unwilling to be the status quo do not seem to think that there is any harm in being a chieftain like Jiaozhi. However, in this way, they inevitably suffer from royal suspicion. This involves the fundamental interests of the Siam King Zhaolu Qunying. How could they be rude? So they had to suppress the pro-Ming faction and even directly slaughter these people. But next, while attacking the pro-Ming faction, could he continue to kneel down and lick the Ming faction by himself? Without showing some tough stance, how could he convince the public?

Hao Fenglou didn't say anything else. He just put the letter on the table, called someone, and said, "If this letter is circulated, Lang San and even the chieftains from all over the country will copy one for them to see it themselves."
