Chapter 1626: Can Anti-Aircraft Guns Create Artificial Rainfall?

Just when Li Yu was discussing with his second and third uncles whether to continue to increase the population limit for entering the trading market, the issue of grain was mentioned.

At this time in the northern border, Old Xie, Xie Weishan and others were also worried about the bumper harvest of grain.

The night was dark.

Because the accumulated clouds in the sky were too thick, the moonlight was blocked.

Above the earth, it was dark, without a trace of moonlight.

It was pitch dark.

The northern border.

The underground warehouse in the inner city.

Xie Weishan looked at the piles of grain and felt a little anxious.

Potatoes, sweet potatoes, corn and wheat were mainly planted in the northern border. Half of them had been harvested these days, and nearly 10,000 tons of grain were stored here.

The warehouse was already half full.

"Captain Xie, when will the transport team come to the North? It's not a good idea to keep the food here. Half of the crops need to be harvested later!"

"It's not easy to preserve so much food. If we can't eat it for the time being, we should quickly process it."

Old Xie rubbed his eyebrows and said:

"I've urged them. The transport team is on the way from the headquarters base to the oil city. It is estimated that they will arrive in the oil city tomorrow."

"After Xiao Hu and his team rest, they will bring the oil to us. It will take about two or three days."

"Four days , they will be here in four days."

"Four days?"

Xie Weishan nodded, "How much can they transport?"

Old Xie thought for a while and replied, "At least a few thousand tons, it should be possible to transport half of the grain in this warehouse."

Xie Weishan curled his lips, "It's only a few thousand tons. In a few days, there will be a few thousand tons of grain harvested in the greenhouse."

"The efficiency of transporting by vehicle alone is too low. It would be great if the train could be restored."

"Train?"

Old Xie raised his eyebrows and felt that Xie Weishan's suggestion was interesting.

Although many railway tracks were destroyed by natural disasters, they should still be usable after repair.

If the train can be restored, the transportation capacity will definitely be great.

However,

He thought that on the way from the North to the trading market and the camphor tree base, there must be some tunnels. There are often many zombies gathering in such places, which is not very safe.

After thinking for a while, he couldn't think of a solution to face the zombie group through the tunnel.

"Your suggestion is good. I'll bring it up to the headquarters when the time comes."

"Okay."

"Let's go. I really didn't expect that in this year of drought at the end of the world, we would be troubled by too much food."

Xie Weishan was amused. "What's the saying? Drought kills, flood kills."

"Let's go, let's get some of the wine that old Yuan Zhi has collected. I haven't been sleeping well recently. Drinking makes it easier to sleep." Old Xie patted Xie Weishan's shoulder.

The two put their shoulders together and walked towards the bar on the eighth floor of the city lord's building.

The city lord is not in the North Territory, and the bar is open.

They don't have that much pressure.

Old Xie is in charge of the military power of the North Territory, and Xie Weishan manages food planting.

Old Xie's real name is Xie Shangzhou. He joined the camphor tree base later than Xie Weishan.

Xie Weishan was an out-and-out farmer before the end of the world. Later, he went to work on the construction site for a living and worked in the construction team contracted by Ding Jiu.

After the outbreak of the apocalypse, he followed Ding Jiu to the camphor tree base and specialized in construction work.

After working for three or four years, he was assigned to work in the greenhouse due to a shortage of people for greenhouse cultivation.

He is a compound talent.

He can build greenhouses and plant crops.

In the northern border, he has several agricultural students to help manage crops. There have been no problems in building greenhouses and planting crops for several months during thunderstorms.

Wushi Military Base.

Ah cut!

Xiao Hu rubbed his nose, raised his head and cursed suspiciously:

"Who is scolding me again?"

He sat on the bed, tickled his toes, then tickled his nostrils, and finally tickled his anus, and put it to the tip of his nose to sniff.

Until he smelled the strong stench, he lay down with satisfaction.

The whole set of combos made the team members sleeping opposite feel a little sick.

"Captain, do we have a vacation this month?" Chang Ze, who was sleeping diagonally opposite, asked.

"Vacation? Why, you want a vacation!" Xiao Hu asked while lying down.

Chang Ze said a little embarrassedly: "I guess my wife will give birth at the end of this month."

"Oh? Giving birth? Sure, congratulations, Old Chang is going to be a father!" Xiao Hu sat up and looked at Chang Ze in surprise.

Wang Chunqi, who was sleeping in the same row as Chang Ze, also smiled and said:

"Sure, Lao Chang, you be the father, and I will be the godfather of your son!"

"Is it OK?"

Chang Ze smiled and nodded and said: "Okay, but we don't know whether it's a boy or a girl yet."

Xiao Hu asked: "The medical conditions at the headquarters base are very good, why don't you test the gender?"

Chang Ze shook his head and said: "Although the base has the conditions to test, there are regulations that prohibit testing."

"Oh." Xiao Hu thought about it and thought that the headquarters base might be worried that everyone would prefer boys to girls, so they didn't allow testing.

"You can take a vacation, and I'll help you adjust the shift when the time comes." Xiao Hu said to Chang Ze.

"Thank you, captain." Chang Ze thanked excitedly.

Asked again.

"Captain, is our trip the same as before? First we go to Oil City, then to the North, then back to Oil City, and then to the headquarters base."

"yes."

Xiao Hu said helplessly: "Captain Xie from the northern border has urged me many times. They have a bumper harvest over there. We have to transport the food to Oil City. I seem to have heard that many survivors have arrived in Oil City recently. "

As he talked, Xiao Hu yawned and felt sleepy.

"Get some rest early, we have to go on the road early tomorrow morning!"

Wang Chun turned off the lights, and the whole bedroom instantly became dark.

A basement dormitory opposite.

In the girls' dormitory.

Zuo Ruxue, Guifei, Li Qi and Cugu lived in one room.

"Aqi, I brought you 2 tons of food from the headquarters base this time, which should be enough for you for half a year. Are you in short supply of water here?" Zuo Ruxue sat cross-legged on the bed and asked Li Qi.

Li Qi shook her head, "There is no problem with water resources. There is abundant groundwater here. There are only a few dozen of us, so it is completely sufficient."

She looked at the imperial concubine and Zuo Ruxue and said with emotion:

"Sometimes I envy you. You can travel everywhere. You can see the Northern Territory, Da Zhangshu Base, and the Oil City Trading Market. I heard that the business district of the Trading Market is very lively."

“It’s a pity I didn’t have a chance to see it”

"Standing in this dark military base every day is boring to death."

Zuo Ruxue smiled and shook her head and said:

"You still say this. Xiao Hu and I stayed here during the months of thunderstorms and natural disasters!"

"It's been half a year, and you've only been here for more than four months. What's more, you have set up sentinel patrols outside now. Being able to go out often makes you much luckier than we were then."

"During the previous thunderstorm disaster, we didn't even dare to open the door. Water was rising everywhere outside, and the walls of this underground base were also seeing water. Seeing this situation at the time frightened us."

"Besides, you have so many books and entertainment facilities here now. It's much more comfortable than we were back then."

When Li Qi heard this, she didn't know what to say for a moment.

Before she and Song Qi came to the Wu City military base, Xiao Hu and Zuo Ruxue were stationed here.

Li Qi estimated that in two months, a new group of people would be stationed here.

The imperial concubine lay on the bed, listening to the two people talking without saying a word, staring at the ceiling blankly.

Cugu looked at the concubine's beautiful face and said coldly: "Sister Concubine, you are so beautiful."

The imperial concubine woke up from her daze and said with some embarrassment: "Well, I also envy your majestic mind."

"This is a burden, and the center of gravity is unstable when shooting."

"Sister Guifei, what were you thinking about just now?"

The imperial concubine hesitated and said:

"I was thinking that it's so unscientific that there is such a thick layer of accumulated clouds in the sky that it doesn't rain. What happened to cause this situation?"

Cuckoo scratched his head and said with a puzzled face:

"I don't know either. Anyway, I listen to Sister Li. Why do you think so much? If there is any situation, the headquarters base will definitely notify us."

The imperial concubine looked at Cugu's breasts and then her head.

He smiled and said, "Very good."

The lights were turned off and people fell asleep.

While they were sleeping, Song Qi was still leading the night shift.

Although the Wu City Military Base is relatively hidden, it is far away from the headquarters base and Oil City after all, so the duty work that needs to be done still needs to be done.

The next day.

The sky was slightly bright, although there was light, it was overcast.

A cloudy day.

The sun is blocked by thick clouds.

Big camphor tree base.

Song Zhihong, who was in charge of the natural disaster department, found his second uncle excitedly.

"President, about the artificial rainfall I told you before, the person in charge of the arsenal has made the rain bombs!"

"We can now test using rain bombs to solve the current cloud squeeze problem."

"Oh? So fast?" The second uncle was a little surprised.

Song Zhihong explained:

"The production of rain bombs is not that complicated. They are just filled with silver iodide powder."

"The whole principle is: use anti-aircraft guns to shoot shells containing silver iodide powder to a high altitude and explode. The silver iodide powder becomes ice nuclei, absorbs water vapor in the clouds, and after a series of reactions, raindrops fall."

"Of course, if the rain bombs are ineffective, we can also use another method, which is to spray dry ice."

"Spraying dry ice from helicopters can lower the temperature of clouds and encourage water vapor to condense into water droplets or ice crystals, thereby achieving the purpose of artificial rainfall."

"Yeah." Faced with his long speech, the second uncle only replied with a "hmm".

Then he said: "Okay, just tell Zhou Ran and I'll get someone to prepare the anti-aircraft cannon."

"Okay."

The second uncle contacted Dongtai, the captain on duty who was in charge of wall protection at this time, and asked him to prepare the anti-aircraft guns.

At the same time, I contacted Li Yu, my uncle and others to observe this rain-inducing experiment.

Half an hour later.

Li Haoran's voice sounded from the broadcast loudspeaker at Da Zhangshu Base.

"An announcement is being broadcast. In ten minutes, rain bombs will be tested for artificial rainfall over the headquarters base. Please remember to take shelter from the rain later and be prepared."

And on the outer wall of the city, there was a row of people standing.

Li Yu, Song Min, He Chao, the second uncle, the second uncle, the second uncle, Xiao Jun, Lao Bi, Zhongshi Yang, Bai Jie, Ma Di, Song Zhihong, Zong Jing, Lao Dong and other hundreds of people were present.

Song Zhihong from the Natural Disaster Research Institute sent people to place some utensils with scales and testing equipment on the wall.

To check the effect of this artificial rainfall.

How many milliliters of precipitation per unit area can be dropped by the experimental rain-inducing bomb.

Song Zhihong trotted to Li Yu and reported:

"City Lord, this rain-inducing bomb is divided into four steps."

"The first step is to launch the shells: we use anti-aircraft guns to launch special rain-inducing bombs into the sky.

The second step is to release silver iodide by explosion.

The third step is that water vapor condenses into raindrops: water vapor condenses around the ice nucleus to form raindrops with enough weight to drop.

The fourth step is that raindrops fall: finally, rainfall is formed."

Li Yu was a little speechless. Every time he was going to do something, he said it in such detail. He only looked at the results and everything was result-oriented.

"Let's get started."

As the commander of this artificial rainfall, Song Zhihong was doing such a big job for the first time.

His face was a little excited.

He picked up the intercom and contacted Dongtai, "The anti-aircraft guns are ready to fire rain-inducing bombs."

These rain-inducing bombs are all made in the arsenal at the Dazhangshu base.

Now the arsenal at the Dazhangshu base already has four bullet production lines and one small-caliber artillery production line.

The production line for making guns is still under preparation, but gun repairs can be done.

After receiving Song Zhihong's message, Dongtai immediately issued an order.

"Fire rain-inducing bombs."

"Fire 5 rounds!"

"Fire!"

Boom boom boom boom!

40 anti-aircraft guns fired rain-inducing bombs into the sky.

Swish, swish, swish, swish--

The anti-aircraft guns can fire at a height of several thousand meters. The rain-inducing bombs set off from the wall of the Dazhangshu base, breaking through the layers of clouds, and exploded after reaching a certain height.

Boom! Boom! Boom!

The specially made rain-inducing bomb exploded, releasing silver iodide powder at the moment of the explosion.

Silver iodide powder becomes an ice nucleus in the cloud layer, absorbing water vapor in the cloud layer. Water vapor condenses around the ice nucleus, and the volume of raindrops gradually increases and becomes heavier.

After the rain-inducing bomb is fired, it takes time to take effect.

After watching the anti-aircraft gun fire the rain-inducing bomb, Li Yu on the ground asked: "How long does it take for it to rain?"

Song Zhihong answered: "Generally speaking, one hour."

"One hour?"

"Damn, you should have said it earlier."

After hearing this number, Li Yu took a stool out of the duty room and sat down to wait for the rain to fall.

The people on the construction site in the outer city stopped their work.

They ran under the eaves to hide from the rain, but since the loud noise heard when the anti-aircraft gun was fired, the clouds in the sky have not moved.

"What's going on? It's been ten minutes, why hasn't it rained yet?"

"Yeah, it's useless."

"I think so too. If artificial rainfall is so simple, why do we need to build a water plant?"

Sergeant Luo looked at the sky and said:

"Don't complain. It takes at least an hour for anti-aircraft guns to fire rain bombs. Why are you in such a hurry? And artificial rainfall also has disadvantages. If it rains, zombies will be dead."

"I don't believe it. It doesn't rain when the clouds are so thick. It can't be measured by common sense." Le Ziqing curled his lips and said.

"Then wait and see. What if you lose?" Sergeant Luo looked at Le Ziqing.

"Ten push-ups?" Le Ziqing replied.

Sergeant Luo said with some disdain: "If it rains, you massage my shoulders and feet."

"Forget it, I won't bet. Your feet are too sore and smelly. I don't want to die." Le Ziqing heard the bet and refused with disgust.
