Li An told Li Yu without omission and in detail of the characteristics and benefits of the continuous rat cage, and picked up the cage, got the walnuts just now into the last small iron cage, and then gently removed the small iron cage, Turn on the switch on the side and take the walnut out.

“Haha, this is really interesting, one trap after another trap. These mice that have caught the first trap have no retreat at all. They can only find the way forward, and then they must only fall into the 2nd trap and continue to find the way out. You can only fall into the 3rd trap, and finally into the small iron cage at the end, hahaha! Why is it so interesting? “

Li Yu said with a smile, and carefully observed with this iron cage, such a clever design, he is absolutely unexpected, there are many mouse trapping tools sold on the street, but so ingeniously conceived to catch Mouse God continuously No, basically all are very simple and crude tools. The rest is the highly toxic rat medicine. In the eyes of most people, using rat medicine is very simple and easy to use, which is much more efficient than the mouse trap tool, and A poison is a large piece, and many simple Mouse God traps can only kill one at a time. The efficiency is too low.

If you encounter a place where the density of rats is very high, it is undoubtedly unreliable to use a mouse trap tool. The speed of killing cannot even catch up with the speed of rat reproduction. A mouse does n’t seem to be a difficult task. Rat poison is extremely effective. For these hateful mice, it is a weapon of mass destruction.

But since the effect of rat medicine is far from rat trapping tools, why should we invent rat trapping tools? This is naturally because there are restrictions on use in many places, such as in the kitchen, the yard for raising livestock, etc., the use of rat medicine must be very cautious, because the rat medicine can not only poison to death rats, but also poison to death cats Domestic animals such as dogs, chickens, ducks, geese, etc. can even block humans.

In this way, once the rat poison is ingested by humans, livestock, and poultry, the damage caused cannot be estimated, especially if it hurts people’s lives.

Therefore, in the later generations, many empires no longer allowed the poison of rat poison on the market, in order to prevent some bad guys from buying this poison and taking it to kill lives, so, it was bad.

Therefore, after the poison was banned, when the 100 old people needed to kill rats, they began to use all kinds of strange things.

Although the mouse-trapping tools do not have the large-scale killing ability of rat poison, the trapping effect is not good, but after the invention of the continuous mouse-trap cage, the effect can be greatly improved. The most important thing is that the old 100 people have begun to prevent rodents. Harmful, many homes with buildings have installed screens with stickers, and the room has no holes. Even if it is a sewer, it can also install a baffle to prevent rats from entering, so that rats can’t enter their rooms completely, so naturally don’t worry The rat is hurt.

The continuous rat-trapping cage invented by Li An is actually only a plagiarism work. It is not a tool invented by itself, but no one can see that’s all.

Li An can also see that Li Yu likes this continuous mousetrap a little bit. Although this is a good cage, if Li Yu likes it, Li An is also willing to give it away. After all, it ’s easy to make this stuff. It’s also worthless.

“This mousetrap was just invented in the afternoon today. I just made one. I ’m going to take it back to the house to try it out. If Prince of Guangping likes it, I can also take it to the house to try it. I will try again tomorrow. . “

Li An said.

Li Yu thought for a moment and shook his head, “Forget it, forget it! Since Minister Li is doing experiments, it can’t be disturbed. In addition, there are not so many mice in my house? Go back with this thing? Good, bad. “

“Haha! Anyway! By the way, Prince of Guangping, how come my house came this time, haven’t you always been to the workshop to find me?”

Li An asked.

Li Yu thought for a while and said, “I’m busy for a day today, and I won’t be free until night. When I saw it was too late, I was afraid I couldn’t find you at the workshop, so I came here directly.”

“Surely I’m having trouble again! Tell me about it! As long as I can help, I won’t say no.”

Li An said cheerfully.

Li Yu nodded said: “There is nothing particularly difficult. After the Imperial Court discovered the benefits of the underground passage, it planned to hollow out all the main roads of the capital to relieve the pressure of vehicles and horses. However, in this regard It must be troublesome for Minister Li, but this is not very anxious. When Minister Li is free, you can consider how to arrange it better. “

“Oh, that’s it! For such a small matter, just send a personal notification without saying a word, why should Prince of Guangping run it in person? It’s too kind.”

Li An thought it was a hard thing. It turned out to be an insignificant trivial matter. It was difficult to draw an underground traffic map, not at all, and this is also a matter of great concern to Li An. Although the housing problem in Beijing is extremely serious, However, the traffic problems in some areas are not optimistic. Especially in the bustling Commerce District of Beijing, the traffic pressure is also very large, and it must naturally be resolved. Otherwise, the city will be paralyzed, just like a person having a blood clot.

“Haha! How can this be a trivial matter? This is a major event in the capital. Emperor grandfather takes it very seriously. If it is not done well, it will be bad.”

Li Yu said with a smile.

Li An said, “Right, has the terrain channel beside Pingkang Square been completed?”

Li Yu nodded and said: “It was just finished this afternoon, and it was finished with white lime powder. Although the light is still insufficient, it can still see the road below during the daytime. There is no problem for the use. It is already very good. Gao Weng came to see him in the afternoon. He was very satisfied. He also said that the grandfather would also be satisfied. Then, almost at night, the grandfather would let the small court Eunuch subpoena and change the next one. The big task was given to me, let me make a plan first, and submit it one month later, should Minister Li go to see the results. “

Li An gently shook the head, indicating that he did n’t want to see it, because the underground passage was designed by Li An, and what it will look like after it is built, Li An will know what you do n’t have to think about. Vehicles are parked. After other passages are opened, they can still be used to pass vehicles. The benefits are very large, but because this is only an underground passage, it is definitely not possible to carve beams. The grade is definitely not very good. There is no such need at all, so it doesn’t matter whether you look at it or not. It’s good to go to see the luck when you are free, but it’s too late today, so I definitely don’t have to go.

“Minister Li has the drawings in hand! What other good things have been invented to let Xiao Wang see?”

Li Yu asked.

Li An naturally does not need to hide. He handed over the drawings just drawn to Li Yu. These drawings are in duplicate. The first one is in the workshop of Research & Development Center. Many craftsmen are building mobile houses according to the drawings, and it is not at ten o’clock. In the intermittent creation, another drawing was brought back by Li An. The reason for preparing 2 drawings is mainly because Li An is not satisfied with the three mobile house styles, or has some doubts about some details. After getting it back, You can also study slowly or make major changes to design cheaper and more reasonable mobile homes. You must ensure that these mobile homes are cheap and easy to use. These two conditions are indispensable.

Li Yu looked at it for a long time and said, “Minister Li, is this a house or a car! Oh, this must be the train compartment! Not right! There are wheels below, so strange!”

Obviously, the mobile home designed by Li An at present is different from all the products designed before. Although there are some similarities, there are still differences. Therefore, it is justifiable for Li Yu to fail to judge for a while.

Li An said, “This is a mobile house, you can also call it a RV, interesting!”

After speaking, looked towards Li Yu with a smile.

“Moving house, RV, get such a weird thing, what is this for!”

Li Yu was very puzzled and did n’t understand what Li An was doing. Li An surprised him again and again, and many times, he could n’t guess Li An ’s intentions. In fact, he could n’t blame Li Yu, who made Li An’s thoughts are always like a heavenly steed, soaring across the skies? I always dare to think about something that others dare not think about, and it is no wonder that no one can guess what Li An is doing.

Li An said patiently: “Prince of Guangping should be very clear that there are more and more old 100 surnames in Beijing. Traffic jams are a very serious problem, but the problem of Beijing is not only one aspect of traffic jams. The housing problem is also very serious. Many old 100 people have to pay one third of their income, or even half of their income to pay the rent. The house price is so high, it is very unrealistic to want to buy a house to live in. These situations, Many old 100 surnames are complaining! If it is not resolved as soon as possible, it will be very unfavorable for the future development of the capital. I have also thought of many ways, but the effect has not been very good. The Imperial Court has also built a lot of cheap rents. Because of too many obstructions, the rate of construction of rented houses cannot keep up with the increase in the population of Beijing, and the increase in the population of Beijing cannot be separated from laborers and other types of people who need to recruit workers. Units, if there is no workshop that can make a living, the old 100 will not come to Beijing, and since the population of Beijing is a large number of workshops Introduced, they naturally also have the responsibility to solve these people ’s housing problems, so I came up with a solution, that is, from now on, all new workshops must be built within the scope of the workshop enough for all employees to live To ease the housing difficulties of these people. Of course, this is not enough. My subordinates have come up with these mobile houses. They can be pulled together by several people, or they can be pulled on by horses, although they seem small Some, but there is no problem with reluctant to live. Many artisans renting houses do not live so big? So, this mobile house was invented. “

After looking towards Li Yu.

Li Yu looking thoughtful’s nodded, said: “Minister Li is really a pain! This method is really good, let the newly opened workshop solve the living problems of artisans, which will inevitably alleviate the difficulty of living in Beijing, and these You can change the position of the moving house at any time, and stop in the workshop! It is indeed a good note. When will this be reported? “

Li An said with a smile: “No hurry, I have to wait a few days for my plan to make perfect and without blemish, and after making the mobile houses on these drawings, I will meet Your Majesty again, at least You must let Your Majesty see the appearance of the mobile home, otherwise I will be sorry to enter the palace. Your Majesty is old and may not be able to understand clearly by looking at the drawings. Only by seeing the real item can I design it for me. Mobile homes have a better understanding. “

“Well, Minister Li said it makes sense. Can it be done in a few days? When the time comes I also want to experience it for myself and see how it feels to live in this?”

Li Yu said with a smile.

“Have you not experienced the Prince of Guangping, the conditions of the sleeper are much better than these, and there are some advanced carriages that are not much worse than this.”

Li An said.

“Anyway, I want to see, when the time comes to accompany you into the palace.”

Li Yu said.

Li An nodded and said: “Okay! That’s it, I will notify Prince of Guangping after all three cars are completed.”

“Good, it’s getting late, Xiao Wang is going back.”

“I see you off.”

After sending away Li Yu, Li An went to the large backyard and put the continuous mouse-trap cage he had just made into the field. There were often rats here and there, but it was not clear that after a night, he could kill a few rats.

Since you want to catch rats, you must naturally have bait, and you also need a bait that mice like very much. Otherwise, if it is everywhere. They are all delicious. Why should rats get into the cage and eat the bait you put?

Li An chose the delicacy that the mouse likes to eat the most, and also deliberately processed it, smeared a lot of sesame oil on it. This aroma permeates the entire field and is definitely very attractive to the mouse. At least, these baits The attraction is definitely far stronger than the crops in the field, which can completely encourage the rats to be fooled.

After placing the cage on the rat path where mice often pass, Li An left the large backyard and went to rest in his room. Li An believes that tomorrow morning, for example, there will be a good harvest, as long as there are rats in this field, sure The organs that can’t escape the continuous capture of Mouse God’s device, depending on the IQ of the mouse, can’t be avoided.

On the morning of the second day, Li An got up very early. The first thing was not to brush his teeth and wash his face, nor to eat breakfast, but to go to the big backyard to see if the continuous mousetrap had a harvest.

When Li An walked to the large backyard, he heard a familiar voice.
