An hour later.

Li Hang looked at his watch, walked up to Song Zhihong and asked:

"It's been an hour, why hasn't it rained yet?"

Song Zhihong observed the changes in the clouds in the sky and said to himself:

"It shouldn't be, it should be raining...how could it be? Could it be that the water droplets contain too much DI elements? That shouldn't be the case either..."

"What did you say?" Hearing Song Zhihong mumble, Li Hang didn't hear clearly.

Song Zhihong said seriously: "Wait a little longer, it should be about to happen."

Li Hang crossed his hands on his chest and raised his head to look at the sky.

A few minutes later, he saw a black shadow coming towards him.

And as we got closer and closer to him, we could see more clearly.

It's raining, but why is it so heavy?

Bang!

A rainball about the size of a fist hit his head, and his hair was instantly soaked by the rainball.

"Whoops! Such big raindrops? No, rainballs!"

A rainball as big as a fist hit his head, giving him a headache.

Bang bang bang bang!

Countless rainballs fell from the clouds in the sky, ranging from the size of glass beads to the size of two fists.

Almost like hail.

Ta-ta-ta!

In the rain, some hailstones also fell together.

The smallest of these hailstones are as big as a fist, they hit the ground and shattered.

"Run!" Song Zhihong shouted to everyone after seeing the huge hail and rain falling.

Li Yu was right next to the door of the duty room. He reacted quickly and immediately got up and picked up his stool and walked to the duty room.

This rain was so unusual.

Hailstones the size of fists can already be called hailstones.

Generally, hailstones that fall before the apocalypse are no more than the size of mung beans, usually between 5 mm and 50 mm in diameter, but there are also larger hailstones that can reach more than 10 cm in diameter.

The size of hail that is falling now is a very large hail that is rarely seen before the end of the world.

In addition to hail, there were also fist-sized rainballs.

Each rainball was connected in a line, and the rain was very dense. Looking at the scene in front of him, Li Hang finally understood what pouring rain looked like.

This was more exaggerated than any rainstorm they had ever seen before!

Boom, boom, boom!

Ding-ding-ding-ding!

Huge hailstones hit the iron sheet of the crane at the construction site, making a crisp sound.

Even the roofs of some cars in the buffer city were hit by hail with small dents.

"not good."

Anya looked at the huge hailstones and asked Song Zhihong anxiously:

"Didn't you say it's raining? How come it's hailing? There's such big hail!"

Song Zhihong thought for a while and then said: "The rain bombs fired by the anti-aircraft guns have a height of more than 4,000 meters, and there is a chance of producing hail. What's wrong?"

Anya looked worriedly at the greenhouses in the buffer city and rolled her eyes at Song Zhihong.

"With such a big hail, I'm worried it will cause damage to the greenhouse!"

Li Yu frowned when he heard Anya say this from the side.

He stood up and walked over, "Song Zhihong, how long will it rain?"

"this......"

Song Zhihong clasped his thumb nails on his palms and said with some anxiety:

"This time it is just a test. Not many rain gas canisters are fired, but the cloud layer is too thick, and the effect of the tear gas canisters will be maximized. It is estimated that it will take one and a half to two hours."

"However, we launched the rain bombs in the west direction. We have delineated the test locations. The rainfall locations are mainly in the west and outside of the buffer city. There may also be some in the first outer city, but the inner city and the second, third, and fourth outer cities should be

Not affected..."

When Li Yu heard this, he immediately looked at Anya.

Understanding in seconds, Anya picked up the walkie-talkie to contact Li Peizhen and the others to confirm whether it would rain in the inner and outer city.

After Xiao Jun heard this, he moved a table directly, raised his hands above his head and walked out of the duty room.

Look in the direction of the inner city and the outer city.

Taking the first outer city as the dividing line, there was no rainfall in the inner city and several other outer cities, but the rain on their side was extremely exaggerated.

Rainballs mixed with hail struck the table above his head, crackling.

Hail fell from a high altitude and hit his hand holding the table leg.

It hurts!

At the same time, hailstones and huge rainballs knocked the table above his head upside down, and Xiao Jun hurriedly ran towards the duty room.

call--

After entering the duty room, he breathed a sigh of relief.

He said to the people who were looking at him: "Song Zhihong is right, there is no rain in the inner city and several outer cities, but there is hail rain in the front area."

At the same time, Anya also received news that Li Peizhen was staying in the inner city, and she breathed a sigh of relief.

fortunately.

Such large hail may cause damage to greenhouses and affect their food production.

However, the area in front is mainly a residential area. Although there is an agricultural production area next to it, the greenhouses affected are limited.

Moreover, they actually have experience in resisting hail before. The greenhouses use PVC solar panels. PVC materials have high impact resistance, are not easy to break, and can effectively resist external impact and damage.

If it were made of glass, it is estimated that such a large hail would directly smash holes in the greenhouse and destroy all the crops inside.

In addition to using PVC materials that are relatively resistant to damage, they also installed anti-hail nets on the roof of the greenhouse.

This anti-hail net is made of polyethylene material with added anti-aging agents.

Can resist and defend against hail.

Anya stood at the door of the duty room, staring closely in the direction of the greenhouse in Buffer City, observing the impact of hail on the greenhouse.

She was relieved when she saw that the greenhouse had withstood the attack of huge hailstones.

.......

In the crackling hail of rainballs,

The second uncle looked serious, pulled Song Zhihong aside and whispered:

"This hailstorm is different from the expected results you submitted before..."

Song Zhihong replied awkwardly:

"My problem is that we made a mistake in judgment, mainly..."

The second uncle did not listen to what he continued and interrupted:

This chapter is not finished yet, please click on the next page to continue reading the exciting content! "It's not your problem alone, I should have let you do experiments outside..."

The second uncle blames himself a little, and he also bears some responsibility for this unexpected situation.

"in addition."

"Why do such big rainballs and hail fall?"

Song Zhihong thought for a moment and said:

"I think it may be because the water droplets in the clouds contain a large amount of DI elements, which makes them lighter. For raindrops to fall, they must have a large enough volume and mass...that's why rain and hail are so big.

volume."

The second uncle nodded thoughtfully, "Go back and make an experiment summary report, write down clearly the shortcomings of this experiment, and reflect on it carefully."

"Yes." Song Zhihong breathed a sigh of relief.

It's okay to write a self-criticism report, but fortunately there is no accountability.
