"Place a wooden stick here so that the pigeons can catch them easily. The walls of this place must be removable. The pigeons need shelter from the wind in winter and ventilation in spring … …"
The farmers were listening to someone explain at the location of the land bought by Li Family Zhuangzi.
The person explaining was not Li Yi. It was just raising pigeons. There were people in the Tang dynasty who knew how to raise pigeons.
There were also people who used pigeons for competitions and pigeon fights.
Cockfighting, dogfighting, incense fighting, everything had to be done.
If people could raise pigeons for fighting, they could also raise carrier pigeons.
Most importantly, Li Yi had never raised pigeons before. His research was not as good as others.
Raising pigeons was annoying, especially in the city. Pigeons with whistles were noise. The neighbors' windows could not be opened, and there was pigeon poop on their balconies and windows.
More importantly, some members of the association talked about pigeons disturbing the people. Other than being sued, they did not need to worry about being punished.
Li Yi was disgusted by the fact that his countrymen were not willing to sue him. Some people were disgusted by raising pigeons.
He did not know or even want to know about it. He only knew that the roasted pigeons sold were usually 10 to 15 RMB each.
Now, he needed pigeons. In order not to disturb the people, he chose an open area with no people around.
He thought that pigeons could only hatch in spring. He did not expect that they could hatch in winter.
Also, pigeons were willing to lay eggs if the temperature was slightly higher in winter.
Feng Yu checked the information and found that heaters were used overseas, but not in China. All he needed to do was to adjust the walls.
"Xiao Yi, it is not easy to use pigeons for military communications."
Lu Huaishen was hospitalized. He knew that Li Yi had started to raise pigeons, so he told Feng Yu his thoughts.
"It is not easy to raise pigeons, and it is even harder to transport them. But with pigeons, we can take the initiative.
The cost of raising pigeons is not high. Pigeons grow fast, and one person can train a large group of pigeons.
Even if one pigeon costs 10 RMB, as long as it can send messages to key places, it will be profitable. "
Li Yi actually wanted to use pigeons to participate in big battles. He wanted to defeat Tubo in one battle.
Who asked him to not be able to make a telegram now? If only there was a wireless telegram.
From the Tang dynasty to Tubo, transfer points were set up along the way. Telegraph machines were also set up in the various departments of the Tang dynasty at the border.
Then they could take the initiative to provoke Tubo. As long as the Tibetan Army dared to make a move, they would definitely have a route to take.
The troops of the Tang dynasty had binoculars and telegrams from the scouts …
Lu Huaishen didn't know that Li Yi was thinking about something that would change the world. He said to Li Yi, "Pigeons can be eaten if you raise them."
"Why don't you raise chickens and ducks? Raising pigeons is more tiring than raising chickens and ducks. I have to clean up the pigeon house. "Li Yi didn't want to eat pigeons. They were too small and had too little meat.
He continued, "Pigeons are not sparrows. Sparrows eat grain when it's time to harvest it.
Using the Internet, one pile at a time, eat.
Sparrows usually eat insects, so they don't usually catch sparrows.
On the whole, the sparrow ate more insects, but the food it ate was less than the food it ate.
But sparrows flock together. When they're about to harvest, who would be willing to eat their crops? "
Lu Huaishen was speechless.
"I'm too sick," he muttered.
"You'll go back the day after tomorrow. It's a minor illness. You can't treat everyone in the Tang dynasty, but you can treat a small number of people."
Li Yi sighed when he said this.
At that time, he didn't say that he could treat everyone. The good thing was that the country he was in was actually the country with the best medical treatment in the world.
Usually, he would say that the country was good and reimbursed more money. Another country was good and free for all.
When the epidemic happened, it would be obvious who was good and who was bad.
"Xiao Yi, you've spread so many medical books. There are many people who are willing to learn medicine and research.
When the 30 imperial physicians from the Imperial Physician Department are better, they can also teach others.
The equipment may not be as good as yours, but technology will always improve. Don't think about reaching the sky in a single step. "
Lu Huaishen began to comfort Li Yi. He knew that Li Yi had something that others didn't. Li Yi couldn't prepare a set for everyone.
However, Li Yi had indeed cured many people with so many medical books.
Medical books had already been sent to places where newspapers couldn't reach.
As long as Li Yi took out a medical book, it wouldn't be long before all the prefectures in the Tang dynasty had it.
Students talked about medical skills in class because many students were unwilling to learn.
"Learning medicine is very tiring." Li Yi thought for a while and said this.
Then he added, "But it's very profitable to learn it well. It's learning it well, not cheating."
"Xiao Yi, scarecrows scare birds. It won't work after a long time. Use nets to catch them. Nets are also money."
Lu Huaishen changed the topic to sparrows and other birds.
"Make a windmill. Use rope to string together a pile of paper windmills. In the past, paper was expensive, and straw paper was soft. Now we have good paper."
Li Yi casually offered a solution, as if this was a trivial matter that could be easily solved.
"Windmills can also be made with bamboo and big leaf grass. Why use paper? It's just that people will accidentally cut themselves if they touch it, "Lu Huaishen said with a smile.
Li Yi stood there motionless. He was in a daze …
After waiting for a while, Lu Huaishen began to worry. "Xiao Yi, I just thought of something occasionally. It's not practical. Paper is better."
Lu Huaishen thought that Li Yi had finally thought of a solution but was defeated by his own solution. He couldn't take it anymore.
"Yeah, why do I keep thinking about gasoline, diesel, and electric motors? I can also try a pedal propeller. "
Li Yi came back to his senses. He said something that Lu Huaishen didn't understand and then ran away.
If he wanted to draw a blueprint, he didn't need to be so strict. He didn't need to use the five-axis linkage and printing technology.
"Cast it. Use the casting method and then polish it smooth. It's better to put it on a boat than a ship."
Li Yi ran back to the study and drew a curved surface. He chose the points and asked for the degree of distortion.
Next to the surface was a drawn surface. The distance between the curved surface and the surface was the basis for the production process.
The smaller the distance between the points, the more accurate the data.
The denser the points, the greater the amount of work.
When Lu Huaishen needed acupuncture at night, Li Yi finished drawing five fan blades.
He didn't draw three because he was worried that the metal material wouldn't be able to support it.
He threw a stack of blueprints into the workshop and ran to the inpatient department.
"In two days, we might see a very fast boat. It's faster than all the boats now, but it's more expensive."
Li Yi inserted the needles into Lu Huaishen's body. He looked at the food delivered from the cafeteria and said something else.
Lu Huaishen's condition at night was better than during the day. The food delivered to him was bland.
"Did you think of something new after listening to what I said?" Lu Huaishen stared at Li Yi.
Li Yi smiled. "Inspiration came. I can't help it!"
