Big camphor tree base.

Under the outer wall, flames burned, burning zombies.

In the flames, these zombies were burned by gasoline and emitted a foul smell.

After the rain stops, the zombie stack no longer increases in height. Instead, the stack height decreases due to the reduced sensitivity of the zombies.

Even if you don't use gasoline to clean up the zombies outside, as long as you wait until the sun comes out, the zombies will recede.

But even if the sun comes out, these zombies won't be able to move too far away. It's better to eliminate as many zombies as possible now that the zombies are concentrated.

The sky becomes brighter and brighter, and the sun is about to come out.

Everyone followed Li Yu's instructions and wrapped their bodies tightly.

In the inner city.

Li Yu entered the underground core power room of the base.

Looking at Dong Ying and others in the power room, they asked: "The sun will come out soon, and now the power system is all shut down. You just said that you can build a magnetic screen to restore part of the power supply. How long will it take?"

Dong Ying thought for a while and said: "Five hours, give me five hours and the corresponding materials, I can make a small magnetic screen."

Li Yu made a mental calculation.

The area in the base that needs to be restored to power most now is the freezer, which stores a large amount of meat and some easily perishable materials.

The freezer is located underground and is well insulated. Plus, it is frozen now and there are a lot of ice cubes inside.

As long as you don't open the freezer door and the hot air doesn't get in, there should be no problem if it lasts for ten hours.

"Five hours? Okay, I'll give you five hours, Xiaohang, you are responsible for finding the relevant materials Dong Ying needs." Li Yu felt relieved and said to Li Hang.

In the Dazhangshu Base, the collection mission and cooperative personnel system that have lasted for so long have allowed the Dazhangshu Base to store a variety of materials and items.

These things may seem useless at ordinary times, but they can play a great role in some special situations.

For example, if you bring these cables that Lao Huang and the others found before, the Zhangshu Base will give you food in exchange for them.

In principle, all soft magnetic materials with high magnetic permeability, such as electromagnetic pure iron, ductile iron, permalloy, silicon steel, soft magnetic ferrite, etc., can be used as materials for the magnetic screen.

Not all of these things are available, but some of them are.

Old Dong listened quietly beside him, walked over and whispered to Dong Ying: "I will help you later."

Lao Dong is an electric power expert. This is actually a relatively simple matter for him. In his opinion, it can be done in less than five hours, maybe three hours?

But he didn't speak, just silently supported his daughter.

At present, only part of the power can be restored. It is still possible to meet the power demand of a freezer, but it is not an easy task to restore more.

This magnetic storm will not only affect the power grid, but will affect all electronic equipment.

Even if you use a diesel generator to generate electricity, as long as you use a generator, there will be a transformer, and the transformer will be damaged during a magnetic storm.

"City Lord, let's hurry up and make the magnetic screen now. The maintenance factory in the outer city has work tables and complete equipment. It will be faster to make it there." Dong Ying said to Li Yu.

Li Yu nodded and said, "Okay, then go and get busy."

Li Hang took Lao Dong, He Bing, Dong Ying and others to the Second Outer City.

When leaving, Li Hang turned off the electrical box and locked the basement door.

I looked at the time and saw that it was five forty-five minutes.

There is already a faint blush on the horizon, and the temperature is rising rapidly.

Wearing hats and insulated clothes, they ran to the outer city.

Li Yu looked at the horizon, always feeling a little uneasy in his heart.

Suddenly, he heard the sound of water flowing from the underground drainage pipe.

Then I remembered, yes!

Shantang Reservoir is closed!

It had been raining heavily before. In order to prevent the Shantang Reservoir from being flooded and collapsed by the rain, the drainage gate was opened to the maximum.

After the rain subsided, they closed the floodgates much smaller, but not completely.

But now that the rain has stopped, we must quickly close the sluice gate to prevent the water from Shantang Reservoir from flowing out.

Although it has just rained and there is water everywhere, the following solar radiation will be strong and the transpiration effect will be obvious, which will evaporate the water on the ground. At that time, a water crisis will occur.

If you don’t stock up on water now, it will be too late to think of solutions when there is a shortage of water.

So he called Li Tie and went over to close the floodgates together.

soon.

They ran to Shantang Reservoir and shook the circular turntable with their hands, which required a lot of strength.

In the past, they could be shut down with a push of a button, but now that the power system is shut down, they can only rely on the initial human push.

Li Tie's expression turned red, but he still couldn't push. Li Yu squatted down and pushed together.

Finally, the gate was slowly closed. Li Yu hurried out and took a look at the floodgate. It was completely closed. No water flowed out of the Shantang Reservoir anymore. He was relieved.

It had just rained and it felt a bit dull.

It had just rained, so the air should have been cooler, but now the sun is about to come out, and the temperature is increasing instead of falling.

In order to protect themselves, they all wrapped themselves up tightly, wearing hats, scarves, sunglasses, and long-sleeved gloves...

The whole person looks like a rice dumpling.

After the strenuous exercise just now, they were sweating all over.

Li Tie was so out of breath that he subconsciously wanted to take off the mask and scarf wrapped around his neck and mouth.

"Don't pick it off!" Li Yu saw his action and said immediately.

When Li Tie heard this, his hand paused and he quickly put it down.

The next second.

The sun is out!

A round of golden light shone.

Thousands of rays of light.

Li Tie swore that this was the brightest sun he had ever seen in his life, and it was almost blinding him.

"If you don't want to go blind, don't look directly at the sun." Li Yu reminded.

Li Tie quickly lowered his head. Even with his sunglasses on his eyes, he lowered his head and shed tears.

Solar radiation is no joke, radiation of this intensity contains terrifying energy.

With this kind of solar radiation, eggs can be cooked in one minute.

In less than ten minutes, a person's skin will be burned through.

Exposed to sunlight, there will be a strong burning sensation.

At the moment, the sun has not fully emerged yet, but only a small tip is exposed, which is so powerful.

Along with this, magnetic storms that are invisible to the naked eye are coming.

Dong Ying and others who had arrived at the maintenance factory saw that the maintenance room suddenly became brighter and knew that the sun had come out.

Dong Ying glanced at the magnetic storm detector placed next to him. The pointer had already pointed to the highest position and was still shaking uncontrollably. It was obviously over the top.

Dong Ying took a breath and said to his father next to him: "Dad, look at the magnetic storm detector, this..."

Old Dong was also a little surprised when he saw it, "So tall!"

He Bing, Lao Luo, Zhou Ran, Xue Zhihua, Wang Yin and others among the top professors and students who had fled from the southwest also heard the news and came over.

This matter was very urgent, so I asked these people to come over to help. Xue Zhihua is a mechanical engineer, and Wang Yin is a master of materials science.

"Is this? Exciting?" Li Hang and Yang Tianlong came in pushing some materials. Seeing them forming a group, Li Hang swallowed his saliva and asked.

"Yes, that's amazing. Fortunately, the power system was turned off. Otherwise, the power system in the base would have collapsed. The factories, heating equipment, lights...all in the base would have to be shut down." Lao Luo, who was standing next to him, said.

said.

At this time, everyone looked at Dong Ying with a hint of respect. In their opinion, if Dong Ying hadn't discovered it, maybe the power system would have collapsed.

The materials were brought over and they quickly got into production work.

But as the sun rose outside, they gradually felt a little hot.

When it rains heavily, the body temperature may be less than ten degrees, so most of them wear more than two pieces of clothing.

But at this time, as the sun came out, a dense line of sweat formed on their backs.

Lao Luo looked at the open door, walked over and closed it.

Then he took off his coat and continued working wearing only a long sleeve on his upper body.

The other side.
