Chapter 721 New Inspiration for Building a Pigeon House

Put a wooden stick in this place so that the pigeons can catch it easily. The wall in this place must be removable. The pigeons need shelter from the wind in winter and ventilation after spring..."

At the location of the land bought by Lijiazhuangzi, the villagers listened to others' explanations.

The person explaining it is not Li Yi, he just raises pigeons. There is no need for him, there are people in the Tang Dynasty who know how to raise pigeons.

There are also people who use pigeons for racing and fighting pigeons.

Cockfighting, dogfighting, incense fighting, whatever it is.

Anyone who can raise fighting pigeons will naturally raise homing pigeons as well.

The key is that Li Yi has never raised pigeons, and his information research is not as good as other people's actual operations.

Pigeons are annoying to keep, especially in cities. The whistled pigeons are noisy, the neighbors’ windows cannot be opened, and there are pigeon droppings on balconies and glass.

What's more important is that there are members of the association who communicate with pigeons on daily basis. Apart from being sued, they basically don't have to worry about being punished.

But the Chinese people were unwilling to prosecute, and Li Yi was disgusted because some people were disgusted with raising pigeons because of their human nature.

He doesn't have access to it, so he doesn't know, or even doesn't want to, understand. He only knows that the roasted pigeons sold usually cost ten to fifteen yuan each.

Now he needs to choose an open place, an uninhabited area for several miles around, in order not to disturb the people.

He thought that pigeons could only hatch after spring, but he didn't expect that they could hatch in winter as well.

And as long as the temperature is slightly higher in winter, pigeons are willing to lay eggs and hatch them.

Checking the information shows that heating is available in foreign countries, but it is basically not used in China. Just adjust the surrounding panels.

"Xiao Yi, it's not easy to use pigeons for military communications."

Lu Huaishen was hospitalized. He knew that Li Yi had started raising pigeons and expressed his thoughts.

"Raising pigeons is not easy, and transporting pigeons is even harder. But with pigeon communication, you can take the initiative.

The cost of raising pigeons is not high. Pigeons grow fast. When training, one person can train a large group.

Even if a pigeon costs ten thousand yuan plus transportation fees, as long as it can spread the news to the key place, it will be profitable. "

Li Yi actually wanted to use pigeons to participate in a big battle, and he could defeat Tubo in one go, which would take many years of training.

Who makes him unable to make a telegraph now? If there is a wireless telegraph.

From Datang to Tubo, transfer points were set up along the way, and various Tang ministries at the border also had telegraph machines.

Then you can take the initiative to provoke Tubo. As long as the Tubo army dares to move, there will definitely be a marching route.

Datang's troops also had telescopes, and in conjunction with the scouts' telegrams...

Lu Huaishen didn't know that Li Yi next to him was considering an epoch-making thing. He said to Li Yi: "You can eat pigeons if you raise them too much."

"Why not raise chickens and ducks? Raising pigeons is more difficult than raising chickens and ducks. You always have to clean the pigeon house." Li Yi didn't want to eat pigeons, which were too small and had little meat.

He continued: "Doves are not sparrows. Sparrows eat food when it is about to be harvested.

Use the Internet, net a bunch of them at a time, and eat them.

Sparrows usually eat bugs, so sparrows are not usually caught.

In the grand scheme of things, a sparrow eats more bugs and eats less grain than the bugs it eats.

But sparrows flock together, and when it’s time to harvest, whose field will they eat the crops in? Who would be willing to do so? "

Lu Huaishen: "..."

"I'm too ill." He muttered.

"You will go back the day after tomorrow. You can't cure the entire Tang Dynasty for minor illnesses, but you can still cure a small number of people."

Li Yi sighed when he talked about this.

He didn't say at that time that he could cure everyone. What's better is that the country he was in actually had the best medical care in the world.

I usually say that the country is good and the reimbursement money is high. Another good country, free for all.

When it comes to the big epidemic, it’s clear who is good and who is not.

"Xiao Yi, you have spread so many medical books, more people are willing to learn medicine, and more people are willing to do research.

When the thirty imperial doctors from the Imperial Medical Office are good at medicine, they can also teach it to others.

The equipment is not as good as yours, and technology will always improve. Don’t think about reaching the top in one step. "

Lu Huaishen began to comfort Li Yi. He knew that Li Yi had something that others did not have, and it was impossible for Li Yi to prepare a set for everyone.

However, Li Yi released so many medical books and indeed cured many people.

Where newspapers cannot reach, medical books have been spread.

As long as Li Yi takes out a medical book, it won't take long for all the capitals in the Tang Dynasty to have it.

When students are taught about medical skills in class, it is simply because many students are unwilling to learn it.

"Studying medicine is very tiring." Li Yi thought for a while and said this.

Then he added: "But you can make money if you learn it well. It's because you learn it well, not by cheating."

"Xiao Yi, the scarecrow scares the birds. It won't work after a long time. Use a net to catch them. The net is also money."

Lu Huaishen turned the topic to sparrows and other birds.

"To make windmills, use ropes to string together a bunch of paper windmills. In the past, paper was expensive and straw paper was soft, but now there is good paper."

Li Yi casually gave a solution, as if such a small matter could be easily solved.

"Windmills can be made with bamboo slices and large leaves. Why use paper? If someone touches it, it will be cut accidentally." Lu Huaishen said with a smile.

Li Yi stood there motionless, distracted...

After waiting for a while, Lu Huaishen began to worry: "Xiao Yi, I just think of something occasionally. It's not practical, so paper is better."

Lu Huaishen thought that Li Yi had finally come up with a solution, but was defeated by his own solution, and he was confused for a while.

"Yes, why do I always think about gasoline engines, diesel engines, and electric motors? You can also try pedal-operated propellers."

Li Yi came back to his senses, and said something that Lu Huaishen didn't understand, and then ran away.

He didn't need to be so strict when drawing drawings, just about right, and didn't need five-axis linkage and printing technology.

"Cast, use the casting method, and then polish it smooth, put it on the ship, it's better than a ship."

Li Yi ran back to the study, where he drew the surface, selected points, and required the degree of distortion.

Next to it was a drawn surface, and the distance between the surface and each position of that surface was the basis for production.

The smaller the spacing between the points, the more accurate the data.

The denser the points, the greater the amount of work.

At night, when Lu Huaishen needed acupuncture, Li Yi finished drawing it, with five blades.

The reason why it was not three was that he was worried that the metal material could not support it.

He threw a pile of drawings into the workshop and ran to the inpatient department.

"In two days, maybe we can see a very fast ship, faster than all the current ships, but more expensive."

Li Yi gave Lu Huaishen an injection, took a look at the food sent from the canteen, and talked about another thing.

Lu Huaishen was in better condition at night than during the day, and the food sent to him was light.

"Did you think of something new after listening to what I said before?" Lu Huaishen stared at Li Yi.

Li Yi smiled: "Inspiration came, there is nothing I can do!" Literature
