Ang Lee heard a familiar sound. Naturally, it was the sound of mice squeaking, and there was more than one. This kind of squeaking sound was relatively impatient. It was almost certain that there were mice in the cage, and it was a group of mice.
The sky had just begun to brighten, and the air was still gray and slightly chilly. On such a cold morning, there was naturally no one in the backyard except for Li An, who was all alone.
A gust of wind blew, and the smell of the grass that had just emerged was blown away. It made people feel the breath of spring in the cold environment. The grass had already emerged, and spring was not far away.
When the warm spring came, the thermal insulation board on the greenhouse could be removed, and the vegetables inside could be better bathed in the sun. At this moment, what Ang Lee could do was to quickly check the continuous mouse-catching magic tool that he put in last night to see how many mice he had caught.
Rats were very sensitive. When someone approached them, their instinctive reaction was to immediately escape. However, if a rat was trapped in a cage, it naturally had no way to escape. Under such circumstances, the rat would appear to be very flustered. It would run around in the narrow cage, emitting anxious and desperate squeaks.
"Haha! I caught a lot of mice overnight! I have to count them carefully to see how many there are. "
Ang Lee walked to the cage and saw a large number of mice that had been caught. He was counting the number, and these mice were obviously not very cooperative. They were even more flustered and ran around in the cage.
"Six, a good harvest. Run, no matter how much you run, I can count clearly, haha!"
Ang Lee removed the small cage of the last trap from the big cage, then took it to the small pool next to him and threw the small cage into the small pool. In this way, he only needed to wait patiently for a moment, and the six mice would suffocate to death.
When the small cage was just thrown into the pool, some waves splashed, and then, it was obvious that the water above the cage was stirring, and the mice were making their last struggle.
The movement on the water surface was getting smaller and smaller, and finally, there was no movement at all. The six mice were all drowned.
To be on the safe side, Ang Lee waited for a while. After confirming that the six mice were all dead, he took the cage out of the small pool.
This small pool was for watering vegetables, and there was a compost pool not far away. It was basically the feces of chickens, ducks, pigs, and dogs. It was placed in this pool to ferment. After the fermentation was complete, it could be used to top fertilize vegetables.
Ang Lee poured all the six mice in the cage into the fermentation pool. Then, he re-installed the small cage in the big cage, and then took it to the open environment 50 meters away to continue testing. After a night of testing, it had been completely proved that this continuous mouse trap cage was easy to use, very easy to use. In the valley where wild boars were raised, weasels and mice would definitely be caught. As long as more of these cages were placed in the valley, the mice and weasels would not be able to escape. There was no need to be afraid of mice and weasels from outside. The cage could be used for a long time, and they could catch as many as they wanted.
This cage was the best for outsiders, because outsiders were not familiar with this cage. When they suddenly saw this cage, they would inevitably feel very curious. Driven by curiosity and greed for food, the possibility of entering the cage to explore was very high, and once they entered the cage, there was absolutely no way out.
Ang Lee sometimes thought that since a little mouse was trapped in the cage, why didn't it tell the mice behind it that this was a trap? It told its companions not to come in and quickly leave here to go to a safe place. In other words, why would the mice behind continue to enter the trap when they saw the trapped mouse in the cage? This seemed to be somewhat unreasonable.
But thinking about it carefully, perhaps in the world of mice, there was also a great deal of selfishness. If a mouse was trapped in a cage, it would not warn its companions who were approaching. Otherwise, how boring would it be to be trapped alone in the cage! Wasn't it good to let other mice be as unlucky as itself? Mice were very treacherous. Why would they warn their companions?
As for the mice that came from outside, although they saw the trapped mice in the cage, they saw that the trapped mice were intact and had not lost their lives. In addition, mice's eyesight was different from humans, and they could not see the whole picture of the cage. They might have thought that the little mice in the cage were eating.
In short, no matter what the actual reason was, this continuous mouse trap was very practical. There was no problem in promoting it to the whole Tang dynasty. Of course, because it was too easy to imitate, there was no need to count on this thing to make money.
After breakfast, Ang Lee went to the R&D Center again. As soon as he went to work, a craftsman came over and placed more than 100 sets of mouse traps in front of Ang Lee. The efficiency was beyond words.
Such high efficiency was inseparable from the hundreds of thousands of workers and a large number of high-tech talents here. Without these foundations, it would be impossible to make so many mouse traps so quickly.
"How is the mobile house? When will it be completed?"
Ang Lee asked.
"Assistant Minister Li, this is not easy to do. It may take two days."
The craftsman said truthfully.
Ang Lee nodded and urged the craftsmen to make the three mobile houses as soon as possible. Then, he asked his subordinates to find a large truck to load more than 100 sets of mouse traps and prepare to transport them to the Lishan Valley where wild boars were raised so that these mouse traps could play their greatest role as soon as possible.
After the truck set off, Ang Lee also set off. How to deploy these continuous mouse traps must be personally participated by Ang Lee. Those guys in the valley may not know what these traps are for.
The weather in the morning was a little cold, but once the sun came out, the weather would soon become much warmer, and there would be more birds in the sky.
Ang Lee looked sideways out of the window. The earth had begun to show a touch of intoxicating green. Spring was coming soon, and spring plowing was not far away. Perhaps it would not be long before there would be a large number of farmers busy on both sides of the road. However, with the advancement of mechanization, the scene of cattle plowing in the past would not be very common. Generally, only the operation of mechanical plowing could be seen.
Soon, they arrived at the valley. Old Zhao came down to greet Ang Lee attentively.
"Alang, what are these cages for? Are they for Eternal Love to catch weasels?"
Old Zhao asked.
Ang Lee smiled and said, "Yes, but not only that, they are for weasels and rats to be caught together. Not a single one will be let go."
Old Zhao asked doubtfully, "Alang, rats are very cunning, but weasels are even more cunning. I'm afraid this cage won't be able to catch them."
Old Zhao obviously did not know much about this cage. He felt that it looked very strange, but no matter what kind of cage it was, Old Zhao did not believe that it could catch weasels. He had made a cage before, but in the end, he did not catch any weasels. The cage he bought on the street was also not very effective. He was so angry that he went to argue with the seller who bought the cage. Therefore, he always did not trust mouse traps and felt that they were not very useful.
Li An smiled and said, "Old Zhao, you're right. Do you know how many rats this cage caught in my house last night? "
"Alang, can this really catch rats?"
Old Zhao still had a look of disbelief.
Ang Lee said with a smile, "How can this be fake? Last night, a cage in the big backyard caught six little rats overnight. Now, the bodies of these six little rats are still in the compost pit in my house. The rats here look no less than in my house. Use this cage, the effect will definitely be good. "
After saying that, he looked at Old Zhao.
"It's so useful!"
Old Zhao could not believe it.
Ang Lee smiled and said, "It's not very difficult to use this cage. I will teach you. Let's find a place to put the cage first."
It was not difficult to guard against iron cages in the valley. However, it was not a place where one or two people could enter casually. After all, there were ferocious animals like wild boars in the valley. If they were attacked by wild boars, it would not be a joke.
The safest way was to have a sturdy vehicle as cover. Although the wild boar was very strong, it was insignificant in the face of a sturdy vehicle. There were no cages in the valley. When the wild boar approached, they only needed to hide in the vehicle and there would be no danger.
Previously, when Old Zhao and the others entered the hinterland of the valley, they used an ox cart with enough defensive power to protect themselves. In front of the ox cart were two strong water buffaloes. They were much larger than wild boars. The cart did not have a roof, but the wooden boards on both sides were very thick. The wild boars could not break through. Moreover, there were three to five people in the cart, as well as Long Hair and bows. If the wild boars went crazy, these people would not be at a disadvantage with sharp weapons.
Of course, these were all to prevent danger. Under normal circumstances, wild boars would not take the initiative to attack them. After all, they often fed wild boars with food. They were already quite familiar with wild boars. As long as there were no special circumstances, wild boars would not attack them for no reason.
However, it was necessary to be vigilant. If they were completely unprepared, once they were attacked by these wild boars, with the fragility of the human body, there was no possibility of survival. Therefore, these guys would not risk their lives and directly walk into the hinterland of the valley.
They needed to take an ox cart to enter the hinterland of the valley. If Ang Lee were to enter, the safety requirements would definitely be higher. He would even need a large number of guards to protect him along the way to avoid danger.
Ang Lee had already prepared for this. This time, there were more than thirty guards and even more vehicles. There would be no problem at all to cover Ang Lee as he entered the valley.
After some preparations, nearly fifty people entered the valley. Such a large number of people and vehicles was a powerful existence for the wild boars in the valley. Therefore, they did not dare to approach at all. Instead, they tried to escape as far as possible. As long as they saw this group of people and felt uneasy, they would immediately run away and even disappear from the sight of the crowd.
The valley was not small, but it was not very big either. The overall scale was relatively ordinary. However, more than a hundred iron cages in the valley did not seem to be too many at all. On the contrary, it seemed a little insufficient.
According to Ang Lee's request, Lao Zhao had built more than a hundred thick wooden fences. These fences were mainly used to protect the iron cages and prevent the wild boars from destroying them. As long as the places where the wild boars could touch the cages were protected by wooden fences, there would be no wooden fences for the places where the wild boars could not touch.
For example, Ang Lee tied an iron cage directly to the trunk of a tree. In this way, the wild boars would not be able to touch it no matter what. As for whether it could catch rats and weasels on the trunk, they would only know after trying it out.
As for how to use the cages, where to place the bait, and how many days to clean them, Li An told Old Zhao everything clearly. Moreover, he asked Old Zhao to carry out his orders seriously. Every time they killed a rat, they would place them in a pool and count the number of rats every month. This could be considered Old Zhao's achievement as well.
Placing a hundred cages was a bit of a task. After placing a dozen cages, Ang Lee and Lao Zhao handed over the task to Lao Zhao. Then, they returned to the R&D Center with the guards. After all, he did not need to do all these trivial things by himself. As long as Lao Zhao learned how to use them, he could leave them to him.
As the spring plowing was getting closer and closer, the need for spring plowing machines became urgent. All kinds of farming tools, seeds, and fertilizers had become scarce materials on the market. Naturally, the R&D Center was also responsible for part of the production tasks, especially in the field of agricultural machines. This was something that could not be replaced by others.
In addition, the machines also needed to be improved. Only by continuous improvement could the machines be more useful and better liberate the farmer's physical strength and energy, making farming a very relaxing and comfortable thing.
Although it was a little idealistic, it was good to relieve half of the pressure. For individual farmers, relieving half of the pressure meant that they could have more plots of land of the same size. For landlords, with better machines, they would need less labor. They could save more money and make more money.
The human heart was greedy. When there was a machine that could save energy, people would want to have a machine that could save energy. This was human nature. When people had a need, they would ask for it and ask the research and development center to improve it. Naturally, the imperial court had the same intention.
In fact, Li An had always been working on improving the machines. However, due to his limited energy, it was impossible for him to take care of everything. Some tasks could only be handed over to his subordinates. As long as they did not go through Li An's mind, the improved machines would rarely make much progress. Most of the time, they would only make minor improvements. If there were no major changes, there was no need to talk about inventing a revolutionary machine.
