In the past, when Li Jie passed by Taijin to Dengzhou, he usually did not stop in Taijin, but immediately got on the boat and went out to sea. After all, Taijin was not very far from Dengzhou, and it took a few hours to arrive. Even if he was tired, he could rest on the boat.

However, in order to take care of the two children, Li Jie deliberately stayed in Taijin for two days. In the past two days, he also took the two of them around in Taijin and told them about the development history of Taijin.

Speaking of which, Beijing and Taijin are both very young cities. Beijing was predecessored by Dadu of the Yuan Dynasty, but later changed to Peiping, and now it has become the capital of the Ming Dynasty. It has only been more than a hundred years. In comparison, Taijin is even younger, and it is a newly built city in recent years.

So compared to Beijing, everything in Taijin is new, the edge of the city is constantly expanding outward, and various residential sites and workshops are also being built one after another. People from all over the country like to come here to settle.

It is precisely these residents from all over the world that have brought various cultures and customs to Taijin, including food and food, and slowly formed their own unique urban culture.

So the two little guys were also eye-opening in Taijin. They even saw the maritime merchants from Nanyang, West Asia and other places for the first time, which made them scream because these maritime merchants are generally not allowed to enter Beijing and can only move in port cities.

Two days later, Li Jie brought his two children to the dock and boarded the steam boat that had been prepared. This was the first time they took the boat, so they were so excited at the beginning. After getting on the boat, they didn't feel quiet for a moment. They almost ran all the inside and outside of the cabin, even running in the steam cabin, and added a few shovels of coal to the stove himself.

It was not until the boat started that the two children calmed down. After all, for those who grew up on land, riding on the boat was actually a very challenging thing, especially after getting on the boat, the foot was floating, which made people feel insecure, so they all sat down honestly.

Taking advantage of the quiet opportunity of the two children, Li Jie also seized the opportunity to explain to them the physical principles of the ship floating on the sea, as well as the development history of the ship, etc. If these things were taught in class, they would definitely seem boring, but in terms of reality, they would seem much more interesting, and the two children also listened with relish.

"Father, is the fastest ship now the steamship we are riding on?" Li Chonghe asked a question after listening to Li Jie's statement.

"Yes, the steamboat abandons the wind power and uses the steamboat as power. Its speed is several times faster than the steamboat or even dozens of times faster. It used to take a month to get there, but now it only takes a few days to get there." Li Jie replied with a smile.

"Why are there so many sailboats outside?" Zhu Wenqi pointed to the sailboat on the sea outside the window and asked. When Li Jie gave them a lecture just now, he used the sailboat outside as an example to let them understand more directly what a sailboat is.

"The reason why sailing boats have not been completely replaced is actually two reasons. The first is that the steam boats have appeared for a short time. Although many people want to use steam boats, they cannot produce steam boat workshops, so they cannot buy them even if they have money."

Li Jie paused and then said: "As for the second reason, it is because steamboats have some shortcomings. For example, steamboats need to burn coal as power and also require a lot of fresh water. If the coal and water are used up and there is no grave to replenish them, the steamboat will not be able to move. Therefore, some long-distance sailing and inconvenient supply areas need to be used for sailing."

"I thought of a good idea. If we install sails on the steamboat, can we use both the advantages of both ships?" Zhu Wenqi said excitedly again at this time.

I have to say that Zhu Wenqi is still very smart, and this idea is indeed very reasonable, but Li Jie still shook his head and said, "Although your idea is good, it has big problems."

"Why?" Zhu Wenqi was puzzled.

"In fact, when the steamboat first appeared, some people did think of this method, but later they gave it up. The reason is very complicated. If we use humans as metaphors, a person wants to learn literature and practice martial arts, but his energy is limited. In the end, even if he practices both civil and military affairs, he cannot succeed in literature and martial arts. He is not attained in both aspects. On the contrary, it is better to concentrate on one subject, so that he can achieve higher achievements in the future." Li Jie explained again.

Sail steamers appeared in the original history, but were quickly eliminated because this kind of ship needs to take into account the characteristics of both steamboats and sailboats. As a result, the four-dimensional effect is made. If the steamboat wants to install a steam engine, it must make great changes to the hull. However, the position of the mast is also very important. As a result, the design conflicts between the two sides are very large. If they are forced to get together, they will only make the ship more mediocre.

Li Chonghe and Zhu Wenqi couldn't understand too many professional terms on shipbuilding, but Li Jie used people to compare them, which made them understand immediately. After all, they still understood the principle that they couldn't eat too much, but they didn't expect that the same was true when using it on shipbuilding.

It was almost noon, and Li Jie saw fishing boats not far away, so he ordered people to come forward and buy a lot of sea goods from the fishing boats. The Bohai Bay is not the Bohai Sea in later generations. There is not much pollution here yet, and various sea goods are also very rich, and sometimes whales can be seen.

The seafood that just cooked was delicious even if it was boiled in salt water. Moreover, there was a special chef on the boat. After the chef processed the seafood and made it into a plate of delicious dishes, the two little guys were very happy. Although they had eaten a few seafood meals in Taijin, they still felt that it tasted more delicious on the sea.

Because they were not in a hurry to rush, the speed was not fast. It was not until the evening that Li Jie and his ship arrived in Dengzhou. As soon as their ship arrived outside Dengzhou Port, a boat came up. Li Jie also saw Zhu Yousan on the bow of the ship at a glance.

Zhu Youzun had been to Dengzhou for a long time ago, and he also brought a lot of people, most of whom were subordinates left by Zhu Su, and some of the staff assigned by Zhu Yunyu to him. They came to Dengzhou for various training, the most important of which was to operate steamships, after all, this was their main means of transportation to Oceania.

"Brother!" Zhu Youzun shouted happily when he saw Li Jie.

Before Li Jie could answer, Li Chonghe rushed out and shouted excitedly to Zhu Youzhuo, saying that Zhu Youzhuo had lived at Li Jie's house before, and Li Chonghe got along well with him. After all, Dier was Chonghe's only aunt, and of course she loved him very much.
