The people on the boat were looking at the people on the shore, and the people were also looking at the boat.
This boat was so fast. It was going against the current and was emitting smoke. How did this happen?
"Hey, your ship is too fast. Whose ship is it?" A person on a ship that had been overtaken and was about to be overtaken yelled.
"Li Family Zhuangzi's steam boat. We don't need anyone." The people on the boat shouted back.
"Even the sails are useless. How can it be like this now?" The people on the boat suddenly felt that they had fallen behind.
He also wanted one. The boat was big and fast, but he did not know how much it would cost to rent it.
"How do we turn this boat around?" Yao Chong was happy to see the scenery, but he suddenly thought of a very important question.
According to the length of the boat, they could sail in the wide part of the river. What about the narrow part?
"Switch to reverse gear, turn the rudder, then turn the rudder, switch to front gear, switch to reverse gear … …" Li Yi gestured with his hands.
It was like driving a car. If they could not make a turn, they would turn back and forth.
The propellers were turning, and the boat would naturally reverse. But it was more difficult to control the rudder as the boat was big.
"This boat was captured. Is it easy to imitate?" Lu Huaishen was concerned about the technology leak.
"I can't make it. This boat is made of iron sheets. No one can learn the welding technology. I am going to use a wooden boat to install the steam engine … …"
Li Yi was confident. No one could make oxygen, and no one could make acetylene.
He explained to everyone what was going on.
In the Tang dynasty, there was brazing. But they used materials that were easy to melt as fillers. It was still okay to make simple things.
To weld iron sheets and maintain the strength of the iron sheets, one must use welding and electric welding.
Using red-hot lead and tin to braze iron and then forging it, who could guarantee that the tension or tearing force of the iron would not be short?
Even if they did not use iron to make the hull, they could still use wood. Would there not be welds in the steam engine?
Gears, bearings, airtight, bolts, etc. If they were not in a hurry, they would not rush the production.
They were worried that there would be problems on the sea route and wanted to make one thing first.
Once they got the steam engine and dismantled it, are you sure you can install it? After installing it, will you realize that you are very good because there are parts that you did not use? You can save them.
"The screws all move differently. You can't just tighten the screws in one place and tighten the other screws one by one.
The steam engine that I built in Zhuangzi needs to be adjusted during installation, or else it won't be sealed well enough.
It involves the problem of the change of the yield stress. This is all knowledge. "
Li Yi concluded and told everyone, "Don't be afraid. Even if you take it, you won't be able to figure it out."
If it was so easy to research, then the aircraft engines that the country imported from Russia could be made by dismantling them?
There was also the machine tools imported from Germany. There was nothing wrong with the original ones.
They were dismantled right away, but when they were reinstalled, they buzzed when they were activated. Some of them couldn't even be installed properly.
Later on, he understood that there was a rule to the screwing of the bolts. It was not enough to screw all the bolts up. There was a sequence to the screwing.
Then, when it was installed, it needed to be heat-treated first. Otherwise, it would not be able to be installed.
"Others can't figure it out by comparing it?" Liu Youqiu stomped his feet a few times to feel the strength of the deck.
"Not to mention the real thing, I even gave them the real thing and the blueprint. I even taught them how to raise the furnace temperature, but they were still dumbfounded."
Li Yi said with a smile. He didn't believe that anyone in the world could make a steam engine today.
Especially the pressure gauge. It looked quite small and showed the pressure. What would happen if there was no such gauge?
Everyone smiled. They now felt that the technology of the Li Family Zhuangzi belonged to the Tang dynasty.
The Li Family Zhuangzi was awesome. It proved that the Tang dynasty was awesome.
Look, you can't make it even if you give it to others, although you don't understand it either.
"It's time to eat. Come in and eat." The chef of the Li Family Zhuangzi on the ship greeted them.
They made beef today. A cow died and was sent over. After Li Yi's inspection, there was no problem and it was edible.
The person who sold the cow said that it froze to death and reported it to the government. The government agreed with this statement.
When Li Yi checked it, he knew that the cow was old and couldn't work anymore.
If it was raised for a whole winter, it wouldn't be able to do much next year. Therefore, he smashed its head with a hammer and then cut its neck.
The cow on the Zhuangzi wouldn't be treated like this. It would be raised until it died. When it was old and couldn't work anymore, two cows would work together. If it really couldn't work, four cows would pull a cart.
For the common people, if the cow wasn't killed, how much food would it eat in the winter? It wouldn't be able to work much next spring. It was better to ask someone to deal with it and then sell it.
The government also knew the situation. They had seen this kind of thing many times. The cow was indeed too old.
Therefore, everyone had beef to eat and treated it as if it had frozen to death.
Everyone on the ship had beef soup to drink. Pieces of beef floated in the thick soup.
Li Yi and the others ate a casserole with tendons and brains, a casserole with chicken and mushrooms, and pork with pickled vegetables.
Li Dan sat on the main seat. Although he wasn't the emperor, as the retired emperor, he had to be higher than Li Longji at this time.
Li Longji and Li Chengqi were on his left and right.
The other ministers sat according to their current positions. Noble Consort Lu, Empress Wang, Wu Jieyu, and the others weren't at this table. Li Yi wasn't there either.
They went to sit with Zhangsun Xin and the others. It wasn't fun there.
Zhangsun Xin's concubine was the most nervous. Anyone of them had a higher status than her.
On the other hand, the eldest madam spoke naturally. She was a family member, even if she wasn't familiar with Wu Jieyu.
Li Yi didn't care about the others. He first picked up mushrooms for Princess Yongmu. Stewed chicken with mushrooms was better than hazel mushrooms and pine mushrooms. Although it didn't look good, it wasn't easy to preserve.
"Wen Tian, eat this. It's cold. Let's nourish ourselves." Li Yi picked up three layers of meat and put it on the garlic sauce plate.
"Mm!" Princess Yongmu's face was filled with happiness.
She was a woman. She should have served Li Yi, but she was always taken care of by Li Yi.
"I want it too." The little guy looked at Li Yi and said.
"Let your sister Xiao Lan help you." Li Yi looked at the distance and shook his head slightly.
"I want you to pick it up." The little guy was angry.
"Say it again." Li Yi's tone was gentle.
"I'm just kidding." The little guy shrank his neck.
Everyone at the table laughed. Xiao Lan picked it up, otherwise how could she be at the table? She sat together in the name of taking care of the little guy.
"Thank you, sister Xiao Lan!" The little guy thanked her. He opened his mouth and put a lot of fatty meat slices into it and chewed hard.
Zhangsun Xin's wife looked at the little guy enviously. She also wanted to give birth to her son quickly and eat as much as the little guy.
Xiao Lan took the opportunity to eat two mouthfuls. She was very clear about her position.
Serving other children could make one feel uncomfortable, but serving the future Crown Prince was not something anyone could do.
Zhangsun Xin's concubine was more sensible. She picked up whatever food there was in front of her and then lowered her head to eat the rice.
Today, she had seen a royal banquet. She could brag about it for a while. Unfortunately, she couldn't say it.
The worst among them had served as a minister in several ministries, while the rest had served as prime ministers and the current prime ministers.
