Carry a fountain with you

Chapter 328 The truth is actually very simple

"No way, there are more than this, you kid can't lie to me, can you?" Professor Zhao was a little dazed, he thought it was a miracle that there were tens of thousands of dragonflies in front of him.According to Liu Junhao's statement, there are estimated to be seven to eight hundred thousand dragonflies, which is unlikely after thinking about it.

"Hehe, old man, you are the god of a small temple, and you have never seen a big offering of incense. Let me tell you, you must have never noticed it before. There are only a few consecutive rains in summer. These dragonflies are like going to a meeting, everywhere. Or If you believe it, I will show you the evidence later." After Liu Junhao finished speaking, he turned and walked towards the house, he turned a blind eye to this kind of dragonfly gathering, which has been much rarer in recent years.In the past few years, there were only a lot of dragonflies, and the sky was covered with darkness, but this phenomenon usually caused other birds to frantically grab food.

Within 2 minutes, Liu Junhao took out a thick book from the room and handed it to Professor Zhao.

"Xiangzhi, is there a record here?" Mr. Zhao asked suspiciously.This Xiangzhi was sent by Zhao Guangming, and he left too quickly that day and forgot to take it back.

"Well, see for yourself, that scene is truly spectacular, and it's unimaginable if you haven't experienced it yourself." Liu Junhao followed up with an explanation.

According to his instructions, Professor Zhao directly turned to the page of anecdotes and strange events, where the records are very clear. In mid-July 1958, Daqingshan suffered continuous torrential rain, and the weather cleared up after the rainstorm.On the wheat fields, vegetable gardens and old thorn trees at Sankeshugantang, there are unprecedentedly rare large clusters of dragonflies, the number of which is more than 7.For several days in a row, dragonflies flew from all directions every evening, covering the sky and the sun.Dragonflies attract countless birds to prey on them. On the branches and straw stacks with a radius of one kilometer, there are about 50 birds standing densely on each tree.According to several elderly people at the time, this situation should be a precursor to flooding.Within half a month, the Baitiao River really swelled, and the water was fierce, causing great property losses to the villagers in several nearby villages.
"Really, dragonflies can predict disasters. Isn't this the same as the earthquake precursor?" They were discussing loudly just now, and two tourists also came over to check.

"What does Professor Zhao think?" Liu Junhao made a fool of himself.

"It's also the first time I've heard of it... I'm a little uncertain," Mr. Zhao replied hesitantly.Naturally, the things recorded in the local annals cannot be faked, which is why Huo Jun decided to increase the price immediately after reading the description of the golden jade bee queen pupa last time.Besides, the scene in front of me is very similar to the records in the local chronicles. It is all about the sudden increase of dragonflies after the heavy rain.After a while, the surrounding trees became lively, and many birds that preyed on insects began to gather here.

"If the water rises, can the dam of your Liujiagou stop it? It seems that it has never been repaired?" One of the tourists completely believed the description in the township annals, and was already thinking about how to retreat.After all, not long after the earthquake, people's nerves were still tense, and if there was a slight disturbance, they would immediately act like frightened birds.

"Don't worry, if the water is going to rise, you can move to the mountain. Besides, didn't you just say that I have encountered this situation of dragonflies gathering more than a dozen times by myself. Is it possible that the water will rise every time? Everyone, use your brains , In fact, the reason is very simple, it is the food chain in biology." Liu Junhao hurriedly brought the topic back, he was really afraid that people would spread false rumors and spread rumors about rising water.

"Food chain? Dragonflies eat mosquitoes... Long-term rainy weather causes mosquitoes to breed, followed by more dragonflies, and dragonflies attract birds to prey, right?" In the end, it was Professor Zhao, who was just indulging in the spectacle of dragonflies. , and now after a little thought, the whole thing has been connected in series.

"Right," Liu Junhao snapped his fingers, and then explained, "Mosquitoes and flies like to lay eggs in places rich in humus, and the firewood beside the wheat field will naturally become moldy and deteriorate after being drenched in heavy rain for a few days, which provides a lot of food for mosquitoes and flies." A good place to lay eggs. There is also this forest, where the wormwood grass is very thick, and mosquitoes like to hide in it."

"That's how it is," the tourist suddenly realized.Some things feel extremely mysterious before you don't know the truth, but when you understand the reason, you suddenly feel ordinary.Taking the scene in front of us as an example, the heavy rain that lasted for nearly a week suddenly increased the number of mosquitoes. Such a good foraging place naturally attracted the arrival of dragonflies, followed by birds to prey on dragonflies.One ring after another, forming a simple food chain.

As if to verify Liu Junhao's words, when it was getting dark, the number of mosquitoes around suddenly increased.All the big grass mosquitoes flew to the ears and buzzed like small bombers.Liu Junhao was sitting in the courtyard to enjoy the shade, but after a while he was bitten by several big bumps on his legs, so he had no choice but to pour some toilet water on his body.But even so, it can't stop those mosquitoes.

"Why are there so many mosquitoes today? Husband, you must buy a few boxes of mosquito coils when you go to the street tomorrow." Zhang Qian was sitting in the house playing with the computer, but she couldn't hold on for a while, and hurried to the yard with a cattail fan to complain.

Mosquitoes were so hateful, they twisted a few big bags on his wife's fair skin, and Liu Junhao helped her apply a lot of toilet water with great distress.Not to mention that people can't stand being bitten, and the animals in the yard are also not feeling well. The red rabbit kept spinning around in the stable, and the cat didn't care about the cold water at night, and directly shrunk its body in the pool, only exposing its head to breathe.

The monkey had no choice but to imitate its master and smear toilet water on its body.The toilet water smelled very fragrant, and Wukong seemed to enjoy the smell very much.In less than 5 minutes, almost half of a large bottle of toilet water was ruined by this guy.

Seeing that the situation was not good, Liu Junhao hurriedly snatched it from its hands.

"Mosquito coils are useless, and they can only work if the doors and windows are closed tightly. But in that case, the mosquitoes have not been smoked to death, and people will faint first." Professor Zhao's deeply touched voice came from outside the door, and his house is no better than Liu Junhao's. Go there, there are so many mosquitoes in the house that they can't get in.It was hot at night, and the couple just ate more than half of the watermelon, and now they are not hungry, so they just came over to chat and enjoy the cool.

"Don't worry about it, look at the savior coming from above." When Liu Junhao saw the bats flying in the sky, he was overjoyed.Look at that direction, it should be flying out of the backyard.One, two, and soon hundreds of them.

It’s really good that comes with good. Years ago, Zhang Qian found a bat nest in the backyard. At that time, Liu Junhao wanted to drive these guys away, but after thinking about human friends, he let them stay. Now it’s time It's time for the bat to repay the favor.

"It's a bat. It's the nemesis of mosquitoes." Professor Zhao also showed a smile on his face. If a bat comes out, it is estimated that all the mosquitoes in the lower courtyard will be caught.He just read the information not long ago, saying that a 20-gram insectivorous bat can eat 1.8-3.6 kilograms of insects a year, most of which are mosquitoes, and can prey on [-] to [-] insects in one night. Humanity is greatly benefited.

The four of them stared expectantly, hoping that the bats would catch all the mosquitoes.But half an hour passed, and the mosquitoes in the yard did not seem to be decreasing, but more and more.Now Wukong couldn't bear it completely, and kept jumping up and down on the ground.

"Husband, it seems that bats don't work?" Zhang Qian asked in wonder, and within a while, she was stung three more times on her arms.

"Indeed" Liu Junhao was also confused.

"I see." Professor Zhao slapped his thigh and shouted: "Bats usually eat mosquitoes at high altitudes. Mosquitoes like this kind of big grass fly close to the ground, and bats can't eat them." It's not that bats can't fly close to the ground, but Their flying advantage is high altitude, so most of the time they hunt at high altitudes, and only when food is scarce will they lower their flight altitude.Today is an obvious exception, as there is no shortage of food in the air.

"Yes, catch it with a grouse." The situation was threatening, and he was bitten badly by mosquitoes. Liu Junhao's brain was spinning rapidly, and then he came up with another trick.Rock chickens can be regarded as good at catching mosquitoes. There are nearly [-] of them in the backyard, and they have been catching and eating them these days.Liu Junhao implements the policy of "eating and supplementing immediately", and constantly catches the chubby grouse from the stone locks and raises them in the backyard, so the number inside has not decreased.

Grab thirty or forty of them and scatter them in the courtyard later. It is estimated that the big grass mosquitoes will be wiped out in less than half an hour.

"Now go catch it in the backyard, and I will go too." Zhang Qian became interested, instead of sitting in the courtyard and being bitten, it would be better to catch the rock chicken.

Professor Zhao and his wife also wanted to help in the backyard, so the four got busy with lanterns and net bags.

There was a cool breeze in the backyard, the sound of frogs, and not a single mosquito, which made the suffering people feel at ease.

Rock pheasants are especially easy to catch at night, as long as they hear the sound and light them with a portable lamp, they will immediately stand still by the ditch, ready to be caught.Liu Junhao originally wanted his wife to help him catch the lamp by himself, but Zhang Qian wanted to do it himself.

My wife's skills are really not very good. I saw the chubby squatting there, but she either blocked the light when she started, or she didn't hold it well and ran away after she caught the chubby. Five is pretty good.Fortunately, there are a lot of rock chickens in the backyard, and her novice caught nearly twenty of them in ten minutes.

"Wow woof" was trying to catch it, when Xiaopi in the front yard suddenly yelled, and then the black panther also yelled wildly.

"There is a situation" as soon as they heard them screaming, a few people didn't care about continuing to catch the chubby, and hurried out of the backyard with a portable lamp.

There was nothing in the courtyard, only Xiaopi and his wife were shouting around under the peach tree.Seeing the master coming out, Xiaopi yelled twice and stopped immediately.

"Could it be that the raccoon is here again?" Liu Junhao walked around the peach tree, but found nothing in the end.On the contrary, the otter heard the footsteps, screamed happily and ran out of the cave, running to his side and circling non-stop.
