When Li An was young, he often used smoke to punish the hateful rats hiding in the underground caves. Although the results were not very brilliant, they also killed a lot of hateful rats, some of them were smoked. I ran out of the hole and was caught, and some were directly smoked to death in the mouse hole. A few days later, it was found that flies were flying around the hole, which is enough to prove that there are dead rats in the hole.

A mouse has a strong ability to punch holes. Sometimes a mouse will make a lot of holes. These mouse holes are likely to be connected to each other. A mouse enters a hole from one hole and is likely to escape from another. How many exits does a rat’s den have? I’m afraid it can only be found by using smoke. As long as the smoke is injected into one of the holes, smoke will come out from the remaining exits. If there is a mouse in the hole, there is no way to escape. The speed of smoke circulation in the hole is very fast, and it is very short. Within a short period of time, you can fill up the internal space of the mouse 鈥檚 nest, which is not too large, so that the rats in the cave are forced to escape, and can only dizzy out of the cave, and then be Captured.

Cigarette smoking is the most convenient and cheapest method of catching rats. There is no other method more reliable than this method, except that the yellow mongoose is not a mouse, and this product may not stay in the hole. If it is climbing on a tree or a cliff In the first place, smoking will obviously not work.

In addition to these mouse trapping methods, there are many other methods, such as dryland rodents, which is also a very effective mouse trapping tool. This method can catch mice live, which is very suitable for catching mice in the field.

However, if this tool is placed in the valley, Li An is not easy to predict whether the pheasant and the hare will be accidentally injured, and the wild boar, 10000 one hoof is caught, the whole device is destroyed The leg of the wild boar will also be injured.

In order to solve the disturbance of wild boar, you can only put the rod of the rodent in a position where the wild boar is difficult to reach. Similarly, in order to avoid the hare and pheasant, you can leave the mouth smaller, or put it in the place where yellow mongoose and mice often appear .

But Li An still feels that this kind of device is not the best. Moreover, only one can be captured at a time, which is too inefficient.

Thinking about it, Li An still thinks it is more appropriate to build a large cage for catching rats. This large cage can achieve continuous non-stop catching of rats. Overall, the equipment is relatively complicated.

This kind of equipment is not a simple trap, but a complicated device with a relatively large size. There is a one-way trap for each and everyone. When the mouse falls into the first trap, the trap will be restored immediately. To prepare for the second mouse, the trapped rat cannot return to the entrance, and can only be forced to continue to move forward, and then fall into the 2nd trap, then the 2nd trap immediately recovers and blocks the entrance, then naturally it is the 2rd trap Until it falls into the last closed small cage, and this closed small cage can be detached. When the inside is filled with rats, it can be removed, and then, the closed small cage is stuffed into the water, Kill all the rats inside, then continue to install them in a large cage and start the next round of rat trapping.

This kind of equipment is very magical, and it can achieve uninterrupted rat catching. Moreover, due to curiosity and gluttony, the mouse will always fall into the trap step by step. The rats behind will see the sound of the mouse here. Being attracted to increase the efficiency of catching mice.

If it is in an area where there are a lot of mice, such a large cage can easily kill more than a dozen mice in one night.

This kind of equipment also has a great advantage, that is, it will not accidentally harm the hare and the pheasant, because the size of the trap is very small, except for the mouse and the yellow ferret can enter, the pheasant and the hare can not enter, let alone the wild boar .

Pheasant chicks can enter. However, as long as the bait in the cage is replaced with meat, chicks will not enter. Only carnivorous mice and yellow ferrets will enter, and the problem is solved.

Li An has decided to make this machine, and it needs to be made bigger, so that more yellow mongoose and rats can be hunted at once, and the outside of the cage needs to be protected by a thick fence, after all There are too many wild boars in the valley, these guys are likely to do bad things after eating and drinking. If they arch with their fangs, there is a great possibility that they will destroy Li An 鈥檚 hard-working catch. Squirrel cages, so, the mice killed will also run away.

“Old Zhao, do you have pen and paper? Get it soon.”

Li An said.

Old Zhao busy said: “There are some, the villain will get them here.”

After I finished speaking, I ran into the room and took out the 4 treasures of the study. Although this product usually does not write, there are still some of these things.

Li An picked up the brush and drew carefully on the white paper. The overall picture of the rat cage and the detailed drawings of each part were clearly drawn. A total of more than a dozen drawings were drawn, even the last. All the assembly drawings have been drawn. With these drawings, and then find the right craftsman, mass production can be carried out.

After drawing these drawings, Li An drew the wooden fence with protection left and right. These were too simple. After drawing, they were handed over to Zhao.

“Master, this is …”

Old Zhao a face of doubt, don’t understand what Li An is going to do.

Li An said with a smile: “I drew a rat-trapping cage. You ca n鈥檛 do these things, but you still did these wooden fences. When you 鈥檙e free, just do it like this and the size. Do some, not many 51, 100. “

“Master, what are these wooden fences for?”

Old Zhao curiously asked.

Li An laughed, said, “What else can I do, of course, to catch the mouse and the yellow ferret, it is not too early, and it will be dark when I go back, do it well, I will go back.”

After finishing talking, he took Yan Ruyu, his son, Tang’er out of the valley.

This trip is not in vain, not only came up with a big problem to solve the housing problem of the population in Beijing, but also by the way, to solve the mice and yellow ferret within the valley, these two animals came to the Li An valley. It is said that it is completely a harmful insect and must be removed. This is a prerequisite for ensuring the large-scale reproduction of hares and pheasants. Under the premise of sufficient food, as long as there are no natural enemies, the breeding capacity of hares is extremely terrifying.

In a sparsely populated country in the later generations, because there are no natural enemies of hares here, the hares of the entire country have become flooded. Even if the army is deployed, this problem cannot be solved. In the end, it can only be cruelly poisoned. The number is still high. It seems that in any case, the scourge of hare flooding cannot be solved, which is enough to reflect the strong reproductive ability of hares.

In the end, there is no way, as long as the natural enemies that can eat rabbits, such as foxes and wolves, are introduced, but because the hare Early-Stage is not well controlled, the natural enemies come a little late, so the effect is not very good, and the natural enemies not only eat hare, but also Some other small animals, among them, nature also includes the key protected animals in nature, that is to say, not only did the natural enemies not eliminate the hares, but also the endangered wild animals in this country. Healed, this consequence is too sad.

The environment within the valley is still too narrow, and the number of yellow ferrets in it is too large, and the number of hares is not at all breeding, and the number does not have an overwhelming advantage. Therefore, under the suppression of yellow ferrets, the number of hares can only be maintained. Balance ca n鈥檛 explode quickly. If you want the hare to breed quickly and provide enough delicious food for the dining table in Beijing, the only reliable way is to eliminate the yellow ferret in the valley. The reproduction must be explosive. I am afraid that I will continue to catch it in the future, otherwise all the plants in the whole valley will not want to survive.

Li An took the drawing and looked at it carefully, thinking about the loopholes and the areas where improvements could be made. For the final mouse trapping effect, the equipment must be good enough.

“What does Husband look at? So serious.”

Yan Ruyu asked softly.

Li An laughed said, “It’s nothing. I invented a rat-trapping cage, just to see where there are still unsatisfactory places, so I can modify it.”

“Catch a mouse, actually need such a complicated cage.”

Yan Ruyu asked suspiciously.

Li An nodded and said: “The mouse cage invented for husband is not a general mouse cage. This mouse cage can continue to kill mice. The effect is much stronger than those of the mouse cages sold on the street. It is not a grade, if it is easy to use, it will definitely be promoted in the future, so that the old 100 people across the country will use such cages to kill mice, hey! This thing is a bit more expensive, the old 100 people of the poor, I’m just afraid to spend so much money. “

At the thought of cost, Li An feels that his invention is still flawed, that is, the problem of price. The structure is complicated and the size is large. In this way, not only the material cost is relatively high, but also the labor cost is also relatively high. The price is naturally It 鈥檚 not cheap. If it 鈥檚 a batch, the cost may be lower, but it 鈥檚 not much lower. In general, it is relatively expensive. The average old 100 people are estimated to be more willing to use smokeless irrigation, which is a cost-free method. Or spend a small amount of money to buy some rat medicine, the effect is called an immediate effect.

“Are you hungry?”

Li An looked towards Shuang’er and Tang’er, asked.

It 鈥檚 been a few hours since I ate wild boar, but they ate a bit too much. At this moment, It should n鈥檛 be hungry.

“Not hungry.”

Tang’er and Shuanger shook their heads.

Li An was a bit hungry. When passing by a pastry shop, Li An stopped and asked the servant to buy some pastries.

“Master, these are enough!”

Li An nodded and said: “Enough is enough, let’s go! Take this Young Lady home.”

Tang’er said immediately: “Father, let the two live in our house! Our family has so many big houses, and their house is broken.”

Li An scolded: “Do n鈥檛 talk nonsense, no matter whether it 鈥檚 a big house or a small house, there is Shuang鈥檈r 鈥檚 home. Shuang鈥檈r 鈥檚 father mother is waiting for her at home? How can they take other children 鈥檚 children home without their consent? What about? “

“Father, Shuang’er’s father mother will definitely agree, Shuang’er, you say yes!”

Tang’er said with a smile.

The two children looked at Li An quietly, did not speak, and did not know what was in their hearts.

Yan Ruyu said: “Even if this time is not, the family is not prepared, you can first ask Shuang’er’s father and mother, next time you have the opportunity to take us to live at home, okay.”

“Oh, then next time! Must talk and count!”

Tang’er seemed a little unhappy, and grunted.

Soon, Shuang’er’s home arrived. Across the distance, Li An saw a woman standing at the junction of the yard and kept looking around, apparently waiting for the return of Shuang’er.

This is mother’s deep concern for child. As long as your child has not returned, the mother will be worried, and I always feel uneasy. Therefore, going out and welcoming you will be more comfortable. After all, it’s already dark, and it’s not normal to worry about it.

“Come on, Shuang’er, when you get home, take these pastries. This is for you.”

Li An handed over some pastries just bought to Shuang’er.

“Shuanger, hold it!”

Tang’er personally took the pastry and stuffed it into Shuang’er’s hands, then got off together, and Yan Ruyu got off.

“Don’t come in and sit down?”

Seeing Li An not getting off the bus, the woman seemed to understood intent and said.

Yan Ruyu said: “It’s getting late, so I won’t go in again. Can I take my two sons to my house for the next night? It’s also fate, Tang’er always haunts her.”

“Wife is so worthy of the twins, it’s the blessing of this child, naturally it works.”

Said the woman.

“What about you Husband? It’s so late, haven’t you returned yet?”

Yan Ruyu didn’t see the man, curiously asked.

The woman said, “I have found a new job, and I will come back very late. It is like this every day. This is the life of a coolie. It is not up to me to decide when to go to work.”

“It’s hard work, it’s so late.”

Yan Ruyu sighed.

“Wife doesn’t have to care, it’s the same for us poor people, every family is like this, we are used to it, and it’s okay not to come back overnight.”

The woman said optimistically.

Yan Ruyu nodded said, “Don’t say much, Shuang’er’s business is so settled. I will go back and clean up a house in the next few days. I will let Shuang’er go to my house for a few nights every month. Like this child. “

“Just listen to Wife.”

Said the woman happily.

“It’s really hard work for these working people! It’s so late, they haven’t laid off work yet, and they can’t make a few dollars.”

Yan Ruyu sighed.

Li An nodded acknowledged: “Look at it! This is what the ordinary bottom 100 surnames do. They do the hardest and most tiring work, and they hold meager wages. For thousands of years, haven’t they been like this.”
