Chapter 38: Rain-making Shells

Afterwards, Wang Haoran went to see Pingu County Director Guo Qing.

After meeting Guo Qing, he told Guo Qing his thoughts.

Guo Qing is also worried about the fact that it hasn't rained for several consecutive days.

Now, Longguo does have the technical capability to create artificial rainfall.

However, most of this technology is controlled by meteorological departments at least at the provincial and municipal levels.

It doesn't mean that if your county needs artificial rainfall, you can get help immediately by applying.

Moreover, the current method of artificial rainfall mostly relies on using airplanes to spread rain-increasing salt powder, silver iodide and the like from the sky.

There is little development of artificial rainfall using rain-making shells.

"Comrade Haoran, do you think you can really do it?" Guo Qing asked.

Wang Haoran nodded: "Really, I can, but this requires your support. I need to make some rain-increasing substances in the chemical plant in this county."

"In addition, I also need the glassware factory to help make fiberglass shells..."

Making rain-increasing shells is not something that can be done casually.

It is best to use plastic for the warhead of the rain-making shell to avoid accidental injury.

The shell body is fiberglass.

It is filled with a small amount of explosives, and also with silver iodide and salt powder in a certain ratio.

Of course, the amount of silver iodide must be very small, because silver is a precious metal after all.

Dry ice is also an important rain-making catalyst, but it is very difficult to preserve. If you want to load it into a rain-making shell, the shell body needs to withstand a pressure of more than 60 atmospheres, which is not very realistic.

It is safer to use silver iodide and salt powder.

But even so, the technical content of this thing is really not low.

Guo Qing waved his hand and said, "Then let's do it!"

"If we can really invent rain-inducing shells, we won't have to worry anymore! Haha!"

"We can always fire a couple of shots when there are clouds in the sky to make it rain."

Therefore, with the support of Guo Qing, several factories in the county cooperated and started producing rain-making shells.

Thanks to Wang Haoran’s technical guidance, the first rain-making shell was produced at around 3:00 p.m.

However, at this time, the sky was clear and the sun was shining brightly.

The conditions for artificial rainfall increase are simply not met.

This makes it impossible to test.

However, the county still produced more than 50 37mm anti-aircraft artillery rain-making shells in one go.

What was Guo Qing doing when Wang Haoran was coordinating the production of anti-aircraft artillery rain-making shells?

He went to the county pesticide factory for inspection.

Because Li Yunpeng called him to report that Wang Haoran had developed a very powerful new pesticide herbicide.

Guo Qing quickly ran over to take a look.

At this time, the grass that had been hit by it had turned completely dry and yellow.

After reading it, Guo Qing was very excited: because being able to produce a new pesticide means the revival of the county pesticide factory!

Guo Qing immediately instructed: "Hurry up and report the invention to the higher authorities, and let the responsible leaders come to inspect it!"

"Comrade Yunpeng, this medicine is of great significance to you. You must hurry up and mass-produce it as soon as possible."

Li Yunpeng said: "Then I'm afraid Comrade Haoran will need to write this report himself. After all, he is the inventor of this medicine."

Guo Qing nodded and said, "You can communicate with Comrade Haoran!"

"In addition, the county will report to praise Comrade Haoran, and you should also express your gratitude appropriately and give him some reward, understand?"

Li Yunpeng naturally agreed.

In the blink of an eye, it was already past 6 o'clock in the afternoon.

Wang Haoran left the county with 20 37mm rain-making shells.

He had checked the weather forecast, which said it would be sunny to become cloudy tonight.

Let's give it a try! If the cloud cover is okay tonight, we can fire a few shells to see if we can get some rain.

Before Wang Haoran returned to Licai Brigade, Li Gang and many members had come again and again to observe the weeds in Wang Haoran's corn field.

Li Gang slept next to the well last night.

He wanted to see if it was his turn to water the fields in the evening. However, he did not get his turn until the next morning.

It was light at around 5 o'clock in the morning.

Li Gang crawled out from under the quilt and went to the ditch to wash his face with water pumped from the pump.

Then he put his hands behind his back and walked towards the edge of the field.

He was anxious to see what was happening to the grass in Wang Haoran's field.

When he arrived at Wang Haoran's field, he carefully observed the dense weeds in the field.

He felt that the grass was noticeably more wilted.

A lot of the grass has become twisted and deformed.

However, they are still cyan.

Li Gang curled his lips and thought: It is indeed somewhat useful.

However, there was not much effect.

At this rate, the grass will probably turn green again sooner or later.

Li Gang took out his pipe and puffed on two pipes.

He thought that when Wang Haoran came back, he would have to tell him: There is absolutely no shortcut when it comes to growing crops, so it is better to be down-to-earth.

Li Gang worked in his own field for more than two hours, and then he went home to have breakfast.

After dinner, he went to see when it would be his turn to water the fields.

After seeing this, Li Gang became discouraged.

Because, there was a power outage.

Once there is a power outage in the countryside during the day, it is basically impossible to tell when the power will be restored again.

Li Gang went to the field to weed again.

He even thought about fetching water to save the seedlings.

It was past 11 o'clock in the morning and the weather was so hot that Li Gang planned to go home.

In fact, there is not much grass in his field now.

He is now waiting to water the fields.

Li Gang came out from his field, covered in sweat again.

Li Gang wiped the sweat off his face with a towel at the edge of the field, and looked in the direction of the well, but there was still no electricity.

Li Gang's heart felt like it was on fire and he was extremely anxious.

While taking out his pipe to smoke, he took a look at the weeds in the corn field contracted by Wang Haoran.

Upon seeing this, Li Gang was stunned.

Because the broad-leaved weeds in the field have basically withered completely.

Li Gang was shocked: It seems that the herbicide made by Haoran is really effective?

The originally dense grass in the fields has now all withered on the ground.

Want to live again?

There should be no possibility.

"Li Gang, what are you looking at?" Li Jieshi walked over and asked.

"Brother Jieshi, didn't I tell you yesterday? Haoran claims to have developed a herbicide that will kill grass in 24 hours. You came just in time, come and take a look..."

When Li Jieshi looked over, he was also shocked.

He ran through the cornfield contracted by Wang Haoran and found that most of the grass in the field had withered.

Li Jieshi said, "Oh my god! Once this thing hits the weeds, all the grass will die. Then we don't have to pull the weeds over and over again!"

Weeding has always been the most tedious work for farmers and needs to be done over and over again.

Li Gang nodded and said, "Who said it wasn't?"

"Let's talk to Haoran when he comes back in the evening. I also want to use this good stuff."

……

In the evening, when the car that was taking Wang Haoran to the village entrance just arrived, Wang Haoran saw Li Jieshi and Li Gang standing there.
