The wheat was already green and knee-high, and the sound of the frame was endless on the banks of the Darong River.

Walking to the foot of Puhe Mountain, this piece of wheat field that was once divided for Pu Yi's family to irrigate, the lotus leaf water transport device brought up a bubbling clear river water like a mountain spring in the forest into the wheat field.

But if you look up, you will find that the wheat that has been tasseled halfway up the mountain is withered and yellow, and I am afraid that as long as you throw a spark into it, it will burn a large piece, and it seems that this lotus leaf water lifting device has not been able to lift the water up the mountain.

Zhao Ruoxin frowned slightly, according to the record of the gene chip in her head, this device was designed and invented by a famous Chinese hydraulic scientist after the reform and liberalization of the previous life.

Zhao Ruoxin was thinking about it, when she suddenly heard a rattling sound, turned her head to look, and immediately saw a tenant farmer covered in patches and said dejectedly: "Boss, our device conveyor belt is broken again, hey~~~ This thing is good, but this conveyor belt is not used, and if it goes on like this, the cost can exceed the grain produced."

Immediately, the shouting tenant farmer walked up to the big child with a black belt, and the child looked depressed, and it seemed that he had long been dissatisfied with the lotus leaf device that carried water.

Zhao Ruoxin was a little puzzled, and stepped forward to ask, "Uncle, what's the matter, what about the land on the mountain?" Anyway, you don't need people to carry water, so why don't you water the land up the mountain together? There are only a lot of rivers by the river, and the big head is still on the mountain."

"Phew"

The tenant farmer spat and said helplessly: "Childe, don't you know, this thing is indeed a good thing. Xiao Lao'er also admires the person who can invent this thing, but if it goes higher, our conveyor belt can't bear the weight and will automatically break, and secondly, because it will heat up and get hot in the process of stirring, and it won't take long for it to break automatically. That is, it is a little better than using people to pick. If it weren't for this, the little old man would have carried his own water to water it, where would he still use this thing?"

Zhao Ruoxin was puzzled. How so? This is a good device that has been proven in practice!

Picking up a conveyor belt that had just been replaced from the side, Zhao Ruoxin immediately found the problem, which turned out to be because there was no lubricating oil and a problem with the pig iron forging process.

Pig iron is this thing. It's not enough to just use fire to quench it, even if it is fired. If a certain proportion of carbon is not added, it is still very brittle, that is, it does not meet the requirements in terms of heaviness.

No lube! Then there is no need to say anything, let alone fever and heat. It's not uncommon for friction like this to erupt even if it's on fire.

"Hey~"

Zhao Ruoxin shook her head helplessly, and then thought of crude oil. That is, the process of refining lubricating oil from stone lacquer that people in this era said she did not have time to teach due to time. Even the Autumn Frost Academy in Chujiazhai can't make such a thing as lubricating oil.

Zhao Ruoxin smiled bitterly, turned around and glanced at the place far away from the river, which was already a large area of the mountains and yellow, it seemed that even if this device was improved now, there was no way to change the result of the disaster.

In the current situation, the area close to the water is not affected, but the farmland far away from the water source is the majority of the area.

Thinking of this, Zhao Ruoxin's heart suddenly began to worry, although whether the drought is not a drought is not something that her little Jing Zhaoyin should care about, but when she thinks of starving to death countless people because of this, her heart is still very uncomfortable.

Walking up a few steps, and looking at the place where the ox pulls the rotating device, the creaking sound seems to be grinding teeth, and the old cow seems to be very difficult, it seems that this thing is indeed as the tenant farmer said, and it is not as useful as imagined.

Because of the reason that the cows kept trampling on the chariot, there was not even a single grass in this place, Zhao Ruoxin looked around and found that only two or three meters away from her, there was a stone that had just been overturned.

Just this faint glance, Zhao Ruoxin's eyes suddenly enlarged infinitely, and her forehead was covered with fine sweat with an extremely shocked expression.

It turned out that the overturned stones, the exposed soil was full of dense white insect eggs, and the upgraded gene chip in the brain had already been automatically analyzed: a long-term drought will be a locust plague!

Locust plagues are mainly caused by drought, which is mainly caused by the many benefits of arid conditions for their reproduction, growth and survival.

Because locusts lay their eggs in the soil, the soil is relatively firm, and the water content is 10%~20% most suitable for them to lay eggs. Drought causes locusts to multiply and grow rapidly, causing disasters in two ways. On the one hand, in drought years, due to the drop in water level, the soil becomes more solid, the water content is reduced, and the ground vegetation is sparse, the number of eggs laid by locusts increases greatly, and it can reach 4000~5000 egg masses per square meter of soil, and there are 50~80 eggs in each egg mass, that is, 200,000~400,000 eggs per square meter

Zhao Ruoxin stretched out her hand and picked up a few insect eggs and carefully studied them in her hand, the information fed back by the gene chip in her brain became more and more detailed again and again, and all kinds of signs showed that judging from the insect eggs in the soil, it seemed that the locust plague had been an unstoppable fact.

Zhao Ruoxin couldn't help but break out in cold sweat on her forehead, according to the time calculation, there is almost half a month, and the locusts in the soil will hatch into adults in a large area, but at that time, the wheat could not be harvested, and others may not know the terrible locust plague, but Zhao Ruoxin, who is a soul crossing, will not know that as long as the locust plague breaks out, the whole country will not be harvested.

In China before the crossing, the number of people who died due to a locust plague in history could not be counted by numbers.

The key is not only the locust plague, but the torrential rain after a long drought, followed by the plague after the flood, especially in such an era, no matter how strong the country, if such a thing really happens, the enemy country in the north takes the opportunity to go south, where there is still food to collect, where there are still soldiers to fight.

Zhao Ruoxin already felt a chill all over her body, and her clothes were wet with sweat, but she still had a trace of luck in her heart, and subconsciously asked the tenant farmers around her: "Uncle, how long has it not rained during this time?" ”

The tenant farmer sighed and replied: "I don't know what happened this year, from the beginning of spring this year to now, it has been nearly two or three months without a drop of water, Gongzi, look at the river below, if it weren't for the reason why the imperial court built a dam last year, I'm afraid there will be no water in the Darong River!" ”

"What? It hasn't rained in a long time? ”

Zhao Ruoxin's cold sweat broke out again, and when she looked at the water level of the river and the rolling dam that was obviously not up to par, she suddenly felt chills all over her body.

God, if a dam of this quality is not dismantled quickly, the locust plague alone could drown countless people if the flood breaks the levee.

Zhao Ruoxin has forgotten that she is mixing silver when she does Jing Zhaoyin, the catastrophe, the catastrophe is really coming, one is not good, I'm afraid that the Great Rong Dynasty is going to die!

Zhao Ruoxin trembled and asked the tenant farmer again: "Uncle, have you noticed that there are more locusts crawling out of the field recently than usual?" ”

The tenant farmer thought for a moment, and then immediately said with his hands dancing and saying, "Hey, how do you know, as long as you turn the ground, sometimes the locusts that fly out can hit your face."

Without waiting for the tenant farmer to finish speaking, Zhao Ruoxin hurriedly ran away, and said in her heart, it's over, it's over, it must be a locust plague!

Xiaocui and You Xiaojiang behind her didn't know why, and when they saw Zhao Ruoxin running, the two of them also followed in one go
