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: "Um...I also envy your great 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, it's so unscientific that there is such a thick accumulation of clouds in the sky, but it doesn't rain. What exactly 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.

Little 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 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 a helicopter can lower the temperature of the clouds and encourage water vapor to condense into water droplets or ice crystals, thereby achieving the purpose of artificial rainfall."

.......

"Hmm." 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 come together 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, second uncle, uncle, second uncle, Xiao Jun, Lao Bi, Zhongshi Yang, Bai Jie, Ma Di, Song Zhihong, Zong Jing, Lao Dong...and so on.

Hundreds of people were present.

Song Zhihong from the Natural Disaster Research Institute sent people to place some graduated vessels and testing equipment on the wall.

Specifically check the effect of artificial rainfall this time.

Experiment with how many milliliters of precipitation per unit area the rain bomb can drop.

Song Zhihong jogged all the way to Li Yu and reported:

"City Lord, this rain bomb has four steps in total."

“The first step is to launch artillery shells: we use anti-aircraft guns to launch specially made rain bombs into high altitudes.

In the second step, the explosion releases silver iodide.

In the third step, water vapor condenses into raindrops: water vapor condenses around the ice core to form raindrops that are heavy enough to reduce weight.

The fourth step is the raindrops falling: ultimately forming rainfall.”

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

"Let's start quickly."

As the commander of artificial rain this time, Song Zhihong was doing such a large-scale work for the first time.

His face looked a little excited.

He picked up the walkie-talkie and contacted Dongtai, "The anti-aircraft artillery is ready to launch rain bombs."

This chapter is not finished yet, please click on the next page to continue reading the exciting content! These rain bombs are all made in the arsenal of the Da Zhangshu Base.

Currently, the arsenal at Da Zhangshu Base already has four bullet production lines and one small-caliber artillery production line.

The production line for making firearms is still under preparation, but repairing firearms can be done.

After receiving the news from Song Zhihong, Dongtai immediately issued the order.

"Fill the rain bombs."

"5 salvos!"

"emission!"

Boom boom boom boom!

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

Boo hoo hoo hoo hoo——

The firing height of the anti-aircraft guns can reach several thousand meters. The rain bombs started from the wall of the Da Zhangshu base and cut through the layers of clouds. After reaching a certain height, they exploded.

Boom! Boom! Boom!

The special rain bomb explodes, releasing silver iodide powder at the moment of explosion.

Silver iodide powder becomes ice nuclei in the clouds and absorbs water vapor in the clouds. The water vapor condenses around the ice nuclei, and the raindrops gradually become larger and heavier.

After the rain bomb is launched, it takes time for it to take effect.

After watching the anti-aircraft guns firing rain bombs, Li Yu on the ground asked: "How long will it take for it to rain?"

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

"An hour?"

"Damn it, I told you 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.

People on the construction sites in the outer city stopped what they were doing.

I ran under the eaves to hide from the rain, but the clouds in the sky had not moved since the loud noise heard when the anti-aircraft guns were fired.

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

"Yes, it won't be useless."

"I think so. If artificial rainfall was that simple, we would still need to build a water plant..."

Master Luo looked at the sky and said:

"Stop chirping. It will take at least an hour for the anti-aircraft guns to fire rain bombs. Why are you so anxious... And artificial rainfall also has shortcomings. When it rains, zombies will..."

"I don't believe it. The clouds are so thick and it doesn't rain. I can't measure it with common sense." Le Ziqing curled his lips and said.

"Then just wait and see. What will happen if you lose?" Master Luo looked at Le Ziqing.

"Ten push-ups?" Le Ziqing replied.

Master Luo said with some disdain: "Chuxi, if it rains, you can massage my shoulders and feet."

"Forget it, let's not bet. Your feet are so sore and smelly. I don't want to die." When Le Ziqing heard the bet, he rejected it with disgust.
