Only Guo Zhiyuan knew that this was not a whim. How could people of this era think that all ships in the future were made of steel? Of course, it is indeed a dream to build a steel ship that can run on the sea with the technological level of this era, but it is possible to replace some of the key components on the ship with steel components!

Francis's idea inspired Guo Zhiyuan. He brought all the craftsmen, told them Archimedes' law of buoyancy, and conducted an experiment in front of them. The craftsmen were all surprised. Although they were still skeptical about replacing the key components of the sea ship with cast iron components, Guo Zhiyuan was the boss, so naturally Guo Zhiyuan had the final say, so he started to try according to his requirements.

However, a new problem soon came. The craftsmen found that if cast iron components were used instead of wood components, the requirements for the iron raw materials used were very high. Dongfan's existing iron materials could not meet the requirements, and the effect was not as good as using wood. After hearing the craftsmen's reports, Guo Zhiyuan realized that he had taken it for granted that most of the iron materials used in this era were pig iron, with too many impurities, poor toughness and easy to break. The iron components used on sea boats should not only be tough, but also corrosion-resistant, otherwise it would be a big problem if rust.

There is no way to solve this problem. That is, to use 100 steelmaking. Guo Zhiyuan's level of half a barrel of water can barely produce a blast furnace. Using blast furnace steelmaking can greatly reduce the carbon content in the iron material, increase the toughness of the iron material, and greatly increase the output. However, blast furnace steelmaking also has high requirements for the quality of iron ore raw materials and coal fuel, which is not something Guo Zhiyuan can solve. You must know that the imperial court has very strict control over high-quality iron ore and high-quality coal, and even if you have money, it is impossible to buy it.

The problem here has not been solved, and there are problems with the military factory. After the military factory is fully started, the demand for iron materials and coal has also increased significantly. Originally, Dongbo secretly smuggled iron ore and coal from the inland through the relationship between maritime shareholders who joined the East India Maritime Trade Company, which can barely solve the production needs of Dongbo. However, the court has now become wary of Guo Zhiyuan and is very strict about the investigation of goods and merchant ships between Dongbo, so this road is basically cut off!

Now Guo Zhiyuan was a little worried, and it felt bad to be stuck in the imperial court! This defeat of the Japanese pirates and pirate coalition made Guo Zhiyuan a little drifted. He spread the stall so big, and now he was stuck in the imperial court. Guo Zhiyuan's grand plan could not be implemented at all.

After all, Dongfan is too small, with limited resources, and farming can solve the problem of food and clothing, but it is difficult to fully realize self-sufficiency in order to develop. The imperial court, a giant, does not need to move a soldier or a soldier to deal with Guo Zhiyuan. As long as it is stuck in Guo Zhiyuan's neck, it is enough for Guo Zhiyuan to drink a pot!

But there was no turning back. Guo Zhiyuan had already spread the stall. No matter how difficult it was, he had to find a way to solve it. Therefore, during this period, Guo Zhiyuan was so worried that he could not eat or sleep because of this problem. He lost weight. Chu Wan'er felt so distressed when he saw his appearance, so she forced him out to relax. Guo Zhiyuan couldn't resist and could only let her drag her together.

As I walked, I came to the Free Trade Zone. It is now the busiest place in Dongbo, with crowds and extremely lively. Looking at the prosperous scene in front of me, Guo Zhiyuan's mood has improved a lot. It is said that the fireworks in the world are the most touching of the hearts of ordinary people. It seems that I should come here often to take a walk.

Chu Wan'er seemed more excited than Guo Zhiyuan. Guo Zhi was busy with official duties and rarely accompanied her. Now she had the opportunity to go shopping with Guo Zhiyuan, so she was naturally very happy. She stopped almost every time she walked in a shop, touched here and looked there, Guo Zhiyuan looked at her dotingly, and felt guilty about spending too little time with her, so she simply put aside her worries and focused on accompanying her shopping.

The shop owners and the people naturally recognized Guo Zhiyuan, the prefect. Guo Zhi was approachable and issued a special decree, requiring the people not to kneel down when they saw the officials. Therefore, the people were not afraid of seeing Guo Zhiyuan. They all looked at the beloved prefect with admiration. Those who were brave and greeted Guo Zhiyuan enthusiastically. Guo Zhiyuan did not show off his airs and nodded to them with a smile.

As he was walking, a group of soldiers came up ahead, twisting a ragged young man, and when he saw Guo Zhiyuan, he stopped to salute Guo Zhiyuan. Although there were many people coming and going to Dongfan now, they seemed to be light and light, but in fact they seemed loose and tight. Especially after the last war, Dongfan strengthened the monitoring and review of outsiders. After outsiders arrived in Dongfan, there were strict regulations on the activity area and they were never allowed to move around randomly.

Moreover, the people of Dongfan are also very vigilant. When they find suspicious foreigners will report to the government and soldiers who maintain market order as soon as possible. They are even more powerful than the aunts of Chaoyang District neighborhood committees we are familiar with. They are all sharp-eyed. Therefore, those who have bad intentions think they are confidential, but in fact, they have nowhere to hide when they arrive in Dongfan. Almost every day, spies from the inland are arrested.

Originally, Guo Zhiyuan would not ask about such a small matter, but since he met him, he still asked casually: "But the spy you caught?" Before the soldier in the team replied, the young man struggled and shouted: "I'm not a spy!" The soldier in the team kicked the young man angrily and shouted: "Be honest!" and then reported to Guo Zhiyuan respectfully: "Reply to the words of the master, this man looked around, his appearance was suspicious, and his subordinates were about to take him back to the ward for interrogation!"

Guo Zhiyuan frowned slightly. It seemed a bit rash if he caught someone just because he looked around and looked suspiciously. Moreover, although the young man in front of him was ragged and looked very depressed, his eyes were pure and he did not look like a spy with a ulterior motive. He waved his hand at the soldier and said, "Let him go, I'll ask him personally..."

The soldier let go of his hand, and the young man moved his wrists and said in a angrily voice: "I heard that the governor of Dongfan Guo Zhiyuan loved the people as much as his son, and had good governance. The atmosphere of Dongfan was very different from that of the inland area, so he came here to see him. He never thought that he would catch me indiscriminately and let me suffer an unjust grievance. It seems that he had a false reputation..."

"Bold! This is Lord Guo, don't talk nonsense!" The leader of the team leader immediately shouted loudly when he saw the young man being rude.

Guo Zhiyuan didn't care, waved his hand to the team leader, and smiled kindly at the young man, "This little brother, I, Dongfan, will never incite the people to the people. If they have any extreme actions against you, I will accompany you for them. The little brother has a good conversation, but I am a scholar? I don't know who he is? Why did he come to Dongfan?..."
