Time passed quickly.

In late May, after more than 60 days of growth, the first crops were harvested.

100 billion mu of arable land harvested 58 billion tons of grain.

In early June, the sowing area increased to 200 billion mu.

At this time, agricultural experts invented a new sowing method: assembly line farming method.

The specific operation is very simple, just like an assembly line in a factory.

The ploughing seeds in front are constantly sowing the seeds, constantly moving forward, constantly ploughing and sowing for ten days, one hundred days, three hundred days... It takes tens of thousands of kilometers to travel, and it seems that it will be necessary to move forward until the end of time.

When the tillage seeds are out of the distance, the crops begin to emerge after some time, and when they grow up.

Behind is a pesticide sprayer that follows, weeding and killing insects.

If you need to replenish moisture, a sprinkler will also keep up with you and supplement some fertilizer.

When the crops finally mature, it is time for large combines to be dispatched.

Then a wonder will be formed, and you will find that the tillage seeds in front have just planted the seeds, and the crops in the middle are still growing from small to large, but the crops at the tail are already mature and can be harvested rumblingly.

That is, sow seeds, take care of them, and harvest them.

It forms a farming assembly line.

With the size of the Lobi West Plain, the seeds run at an average speed of 30 kilometers per hour for two months, and only walk 43,200 kilometers, and have enough space to perform their operations.

Moreover, agricultural machinery does not necessarily walk straight lines.

You can also turn around and turn around.

If you encounter a small river, you will directly pass by the water; if you encounter a large and medium-sized river, you will have a professional construction team to build a bridge across the river.

If you encounter a super-large river with a width of more than ten kilometers, there will be large spacecraft that will transport agricultural machinery to the opposite side of the river. There is no need to spend a lot of time building large bridges.

If rainfall occurs in a certain place for days and floods are likely to flood the cultivated land, resulting in a reduction in production. There will be dozens to hundreds of giant spacecraft that will pump the water away. Each spacecraft will transport 300,000 tons each time, and transport ten consecutive times a day. If it is not enough, there will be a large number of extraordinary people, using large-capacity space rings to load water and transport water. They can run up to hundreds of trips a day. With such crazy transportation, they can transport up to tens of billions of tons of water every day.

With such processing capabilities, floods that usually occur once in a decade can be easily dealt with.

However, if it is a once-in-a-century flood that is more difficult to deal with, it can only mobilize more extraordinary power, or disperse cumulonimbus clouds in the sky, or dig huge pits on the surface, reduce rainfall in the sky and increase capacity on the ground. The once-in-a-century flood is not undesirable.

As for drought, just transfer the extra precipitation in certain areas to water-scarce areas.

That is, whether it is drought and flood, it can ensure the normal growth of crops and achieve high yields and bumper harvests.

But are there only these difficulties that you will encounter in farming?

Of course it won't be that simple.

Late September.

A crisis of swallowing rats broke out somewhere in the Lobi West Plain.

The swallowing rat is a common type of voles, and there is no particularly big difference between the voles and house rats in other places.

The smallest one is the size of walnuts, and the largest one is the size of a fox.

Except for the rodents, fangs, destructive power and attack power in the mouth are very limited.

Humans and Xuanmeng people can step on to death with one foot.

But it's just a common mouse.

but……

Swallowing rat, different.

First, it has wisdom, quite high wisdom.

Secondly, they will join forces, and over billions of years, they have established rat kingdoms and rat empires underground.

In addition, they have extremely strong reproductive ability. One litter can give birth to eight or ten babies, and four times a year.

Finally, before the Xuanmeng people came to the Luobixi Plain on a large scale, developed the land here, and planted a large number of crops, the Swallowing Rat had become the overlord of this plain. In order to defend their hegemony, countless wars broke out with the Xuanmeng people. Although more defeats and fewer hegemony were weak, it did not mean that the Swallowing Rat would go down the stage of history.

They are just moving underground.

The more food sown on the ground, the better it is to grow and expand.

Therefore, although the countries and people on the West Plain of Lobi are eager for a good harvest, they are not eager for a good harvest, because once a good harvest occurs, the army of swallowing rats will sweep over and plunder all the results, and the good harvest will turn into a desolate year in the blink of an eye.

There is almost no one on the Lobixi Plain that does not hate. Some empires have also sent elite troops to launch many anti-slaughter.

However, this kind of suppression is effective in dealing with small-scale Tianshen rat swallowing. If it faces the Tianshen rat empire, it may be wiped out.

That's right, when you are red-eyed, the swallowing rat has the ability to kill people. With the rat sea tactic, even the can of iron that is airtight, it can bite out a few holes and then drill in to bite into a skeleton.

Some powerful Sky-Swallowing Rat Empires even have an elite Gold-Swallowing Rat Legion that can even be chewed through steel. Xuanmeng people are all despised when they hear it.

With the powerful reproductive ability of the swallowing rat, even if it is severely damaged under the attack, it can recover its strength in a very short time - as long as there is enough food.

There is nothing to do.

For tens of millions of years, Xuanmeng people have been unable to do anything about swallowing rats. Many farmers even chose to surrender and compromise, believed in the so-called "Rat God". Every year, they took out a considerable proportion of their grain harvest and offered it to the "Rat God", just asking the Rat God to show mercy and not eat up all their food.

It seems that these farmers are very ignorant and ignorant, but who would have worshipped a group of voles if they were not for the purpose of living?

But it shouldn't be so bad that the Swallowing Rat actually targeted the Prosperity Army and targeted the "Three Years of Extraordinary" plan.

"Not good! In the Baccarto area, in just one day, our crops were eaten by the Swallowing Rat Legion, and the losses are currently expanding rapidly!"

In the office, Peng Guangxia reported in a panic.

What?

In one day, crops lost 10 million mu?

Zhang Nan sat up.

He immediately sensed it and found that it was true that the crops in the Barktor area were disappearing rapidly, at an extremely astonishing speed.

"Send someone to deal with it immediately and eliminate these celestial swallowing rats!"

Zhang Nan said annoyedly that it was ridiculous that a mere group of voles wanted to become his stumbling block!

"yes!"

The bomber group carrying conventional bombs was dispatched.

The elite prosperity army was dispatched to carry out this rat-killing mission.

Boom boom boom boom ~

Twist ~

A war to destroy rats lasted for three days.

In order to eliminate the celestial swallowing rats, bombers bombed indiscriminately. The elite mecha legion not only used advanced laser weapons, bullets, and artillery shells, but also fired countless rounds.

The effect is naturally very obvious. The number of swallowing rats killed is at least more than 10 billion.

But in the Barktor area, the thriving crops are still decreasing by 5 million mu per day, and the rats are still rampant.

"What's going on? Haven't these voles been wiped out?"

"We underestimate the swallowing rat!"

A military general said: "The Baktor area has always been the territory of the Tianshen Rat Empire. It has ruled for at least tens of thousands of years. The local indigenous people have long chosen to surrender. Every time they harvested, they have to take out 50% of the food they harvested, and they have to give it to the so-called rat god. However, after we rented these lands, the harvested crops in July did not listen to the advice of the local people, and took out 50% of the food and offered it to the rat god. Therefore, the Tianshen Rat was angry and sent out all to eat up our crops!"

"Our military strikes eliminated some of the celestial swallowing rats, but they quickly drilled into the hole, hid underground, and then went to any location in the Baktor area through dense underground passages. Unless they were dug three feet away, they would not be completely wiped out."

Peng Guangxia also said: "Although the swallowing rat is small, its IQ cannot be underestimated. He also dug underground passages throughout the entire Baccarto area. It is useless for us to bombard it indiscriminately. Maybe all the 3 billion mu of arable land in the Baccarto area will be ruined, and even nuclear bombs will not work. This thing is too small and too cunning, and conventional means are ineffective."

"How about using poison gas?"

A adviser said: "Inject a large amount of poison gas into the tunnel where the Tianshen swallows the rat, and poison them all."

"no!"

An expert shook his head: "The poison gas is only useful for small areas, but it will not have a good effect on the kind of authenticity that is well-connected, and it will not kill a few swallowing rats."

"Can you flood with water and poison it in the water at the same time? You have to drink water even if you swallow the rat. If you pollute the water source, you will either die of thirst or drown!"

"None of the conventional means can do it!"

The military expert said: "It can only be solved by high-tech methods, and find ways to produce a large number of mechanical rat killers, go deep into the country of the Swallowing Rat Empire, break into their nests, and then eliminate them one by one, ending all Swallowing Rats."

Suddenly, Zhang Nan's face changed.

Through the sensing of white light particles, in addition to the Baktor area, there was also a certain area where a tide of rat swallowing also broke out, and it was nibbling on crops, and its scale was not smaller than that of rats in the Baktor area.

And according to this trend, it is not ruled out that there will be a third, fourth and even more regions, all of which will have a tide of swallowing rats.

"Okay, it's so noisy, don't discuss it anymore!"

Zhang Nan shook his head, stopped the chaotic discussion, and said, "I have an emergency solution. In this way, I will provide 10 million troll cores of the flame troll. You can send people to two places and place them in places where the rat disease breaks out, and save food first and curb the rampant sucking rats."

"In addition, you send someone to find a way to catch a batch of living samples of the swallowing rats. I want to study and study the robot rat killer, and let the new Xia Kingdom speed up the development. I will come up with a way to completely exterminate the species of swallowing rats!"

Zhang Nan said with a cold face.
