On the TV, a national news broadcast was playing.

[On the morning of May 1, when Li Hegui, a villager of Laorongshu Village, Tianyun City, went to work in the field, he found a large number of "grasshoppers" (locusts) turned into his wheat field from the reeds of the river next to him.

"The flying grasshoppers hit me in the face, and the sky was black, like a big net. It's only been one morning, and the wheat in our village has been ruined, and my family is counting on this wheat to live, what can we do......"]

In the news footage, locusts that cover the sky and the sun fly through the sky, and the wheat fields on the ground and the trees next to them are densely packed with locusts, which makes people's scalps tingle to watch.

Shi Xiaoxiao was a little puzzled, and asked with a pout.

"What's so nice about the news? Isn't it just a plague of locusts? The whole world can't come once or twice that year?"

Ling Yun frowned and shook his head.

"No, according to news reports, this year's locust plague has been somewhat severe...... And the main thing is...... On the news...... It seems to be...... It's Feng Lei's family......

Alas, it is not easy to grow some grain in the countryside, and this locust plague is in trouble, and it is estimated that Tianyun City will have a large harvest this year. ”

Ma Tianyao nodded, but suddenly had a bold idea in her heart.

"Lingyun, pack up your things, let's go to the Suyun branch overnight. ”

"Good!"

Although Ling Yun couldn't understand what Ma Tianyao was going to do, he immediately nodded and agreed.

……

May 3rd, morning!

As soon as the signature dish branch in Suyun City opened, Ma Tianyao hurriedly walked in.

"Master, Master, here!"

Guan Yulin, Zhou Yufen, Wei Hong, Cong Feiyan, and Chen Mei saw Ma Tianyao coming, and immediately ran out of the kitchen respectfully and stood in a row.

For Ma Tianyao, they are different from Feng Lei, Feng Lei and Ma Tianyao have experienced too much, although they are also called Master, they are more cordial.

The five of them felt more respect and admiration for Ma Tianyao, and a little fear and restraint.

"What about Feng Lei?"

"Master! Feng Lei, he ...... He took leave of absence and went home......"

"Take a leave of absence to go home?"

"Well, he said that there was a locust plague at home, and he went to the house to see ......"

"Okay, then you guys are busy. ”

After speaking, Ma Tianyao smiled at the five people, turned around and went out again.

Ling Yun followed behind and hurriedly asked.

"Master, are we going to Tianyun City?"

"Well, go to Feng Lei's house to see the situation. ”

Saying that, the two got into the car, didn't say anything all the way, and drove all the way to Tianyun City, Ma Tianyao followed the navigation, drove for more than three hours, and finally drove to a town.

By the time she reached the town, she could already see locusts.

After a little inquiry in the town, the two asked about the location of the old banyan tree village, and then drove for about ten minutes to finally arrive at their destination.

After arriving at the old banyan tree village, Ma Tianyao directly opened her mouth in shock, the scene in reality is far more shocking than what you see on the TV news, and it can even be described as terrifying.

Swarms of insects that obscure the sky dominate almost the entire sky, the surrounding trees have turned 'locust-colored', and the buzzing of insects and the chewing of plants can be heard in the quiet air.

The dense locusts on the road flew around and made people's scalps tingle, and the cars drove past, making a creepy sound.

Even though it was broad daylight, there was hardly a single person in the village, and the doors of the houses were so closed that they didn't even dare to open their windows.

"Master, this is too terrifying, isn't it?"

"Well, it seems that things are more serious than we thought...... By the way, contact Feng Lei and ask him to pick us up at the entrance of the village. ”

"Good!"

……

After making the call, about ten minutes later, Feng Lei wore a hat, a mask, and a long coat and long sleeves and ran over from afar, waving his hands and shouting thickly.

"Master, there are too many bugs, hurry up and get in the car and go. ”

After getting into the car, Feng Lei led the way, and the three of them drove towards the village for three or four minutes, and finally stopped at the door of a two-story small building with a brick structure.

The three of them covered their mouths and noses and slipped into the door, and then quickly closed it.

Despite this, the moment the door was opened, more than a dozen locusts flew in through the crack in the door.

Feng Lei eliminated these flying locusts one by one, and then he breathed a sigh of relief and poured a cup of tea for the three of them.

"Whew...... Master, why are you here?"

"Oh, I saw on the news that there was a locust plague in your village, and it happened to be fine, so I came over to take a look. By the way, where are your parents?"

"Hehe, it was just built after the year, and the old houses have become dangerous houses, and they leak when it rains, so they can't live in it. My parents have gone to the village for a meeting, and the village is now discussing what to do...... This year's crops could not be saved, so the villagers wanted to fight for it to see if there was any subsidy. In addition, we have to discuss how to deal with these locusts......"

Ma Tianyao nodded, Ling Yun pinched the corpse of a dead locust and looked at it, frowned and said to the two.

"Locusts, belonging to the order Orthoptera, are mainly found in tropical, temperate grasslands and deserts around the world. It mainly includes flying locusts and earth locusts. There are three species of locusts in China: East Asian locust, Asian locust and Tibetan locust, among which East Asian locust has the widest distribution range and the most serious damage in China, and is the most important locust species causing locust plague in China, mainly harming grasses......"

"Do you still have research on locusts?"

"Just read the material. ”

"Well, let's talk about it, what else?"

Ling Yun nodded and continued to popularize science for the two.

"A locust plague is a plague caused by locusts. In the event of a locust plague, countless locusts cover the sky and the sun, leaving no grass in their pass, they devour the crops, make the agricultural harvest fail, and then cause serious economic losses, so that there is a famine and war disaster due to food shortage.

The locust plague is a worldwide disaster, and it has a long history, the locusts are extremely warm and dry, and the locust plague is often accompanied by severe drought, and there is the so-called "locusts after a drought" and "locusts must have locusts after a long drought".

There is a record of "locusts in the dry pole" in ancient books in China very early.

In the "Book of Songs", it was mentioned that "to remove its moth (beetle is locust), and its thief, it is harmless to my field." Tian Zu has a god, and he is a fire." ”

Feng Lei frowned and asked while listening with his foot kicking the locust corpse under his feet.

"I've seen a lot of grasshoppers when I'm so old, but I've never seen a locust plague, this locust plague is really as terrifying as you say? By the way, why is this suddenly so bad......

Ling Yun replied.

"With the general trend of global warming, especially the rise in winter temperatures, this is conducive to the increase of locust overwintering eggs, which provides a new force for the outbreak of locust plague in the coming year. The other is the excessive use of pesticides, which are to locusts what Western medicine is to cold viruses. Usually, the effect is fast, but when the virus really develops resistance, then another outbreak will become a disaster.

The same goes for locusts, spraying pesticides in previous years can quickly eradicate locusts, but when these locusts become resistant, these drugs are ineffective unless stronger ...... appears."

Feng Lei nodded sadly.

"I've heard from experts from the village who say that although this pesticide is available, if it is used on a large scale, it will have a very large impact on nearby water sources and the ecological environment.

Other than that...... The locusts will almost be transferred to other places after they eat, which also provides great difficulties and obstacles to stop the locust plague. Alas, I hope it can be solved sooner, it is really not easy for farmers......"

Speaking of this, Ling Yun frowned and looked at Ma Tianyao, but in the end he didn't open his mouth.
