Now that the power system has collapsed, there is no way to ride in the elevator, so you can only walk down.

soon.

Li Yu and He Chao arrived at the Second Outer City Maintenance Factory.

He took off his heavy helmet, pulled down his radiation protection suit, and tied a knot around his waist.

He Chao from behind came in and closed the door of the maintenance factory.

"City Lord."

"City Lord."

"Brother."

"Xiaoyu."

Seeing Li Yu and the others coming in, Lao Luo, Lao Dong and others spoke one after another.

Li Yu waved his hand and asked: "Is the magnetic screen ready? How much power can be restored?"

After thinking for a while, the old director replied: "It's hard to say. You can only know after trying it."

"Hurry up then, go directly to the inner city to install it now." Li Yu said directly after hearing this.

For the entire Da Zhangshu base, the most important thing is the basement warehouse.

The base's most important supplies are stored there.

Including most food, firearms, seeds, freezers, and even zombie attracting potions.

This warehouse is partitioned, and each area will have different temperature and humidity settings....

And these are all driven by electricity.

There's a power outage now, and they haven't opened the warehouse yet.

Everyone put on radiation protection suits and goggles and followed Li Yu into the inner city.

In fact, ordinary clothes can also block sunlight, as long as the skin is not exposed to the sun, but it is too inconvenient to wrap it up, and some skin will inevitably be exposed during walking.

Moreover, the thermal insulation performance of clothes made of ordinary materials is not that good.

Moreover, some clothes that are not thick enough will have much less effect in blocking solar radiation.

A few minutes later.

Everyone arrived outside the warehouse.

There is a switch in the warehouse that controls the warehouse.

Li Yu looked at Lao Dong, Lao Luo and others behind him. This was his first time bringing people from outside the city here.

Usually, let alone people from the outer city, even the vast majority of people from the inner city are not qualified to enter here.

But now that things are urgent, there is really no other way but to let them in.

However, the underground warehouse is divided into zones, and each area is closed. You cannot see what is going on inside from the outside aisle.

Moreover, the electric switch is set on the right wall behind the second door, so there is no need to go deep into the warehouse.

Li Yu took out the key and opened the first door of the underground warehouse.

Kaka——

The first door was opened, and a second door appeared behind it.

There was a small space between the first door and the second door, and everyone walked in behind them.

Li Yu looked at the people behind him, and then opened the second door.

What greets the eye is a huge space, with a ceiling at least as high as two or three stories, and a very long aisle at first glance.

Li Yu walked to the wall on the right side of the door and said to Lao Dong and the other two: "The switch is over here, let's start quickly."

Upon hearing this, Old Dong quickly picked up the magnetic screen placed on the ground and walked over with Li Tie and others.

Li Yu didn't understand how to operate this, so he could only watch them quietly from the side.

About fifteen minutes later, Old Dong raised his head and said to Li Yu: "City Lord, it's ready here. The next step is to arrange the transformers in the distribution room. Then we can try to open the warehouse."

The switch over here."

Li Yu nodded and said to Li Tie and Li Hang: "Take them over there. After the arrangement is completed, come over and notify me to open this side."

"good."

Then they took Lao Dong and others to the transformer in the distribution room to make arrangements.

After about ten minutes, Li Tie hurried over and asked Li Yu to turn on the switch.

Li Yu turned on the switch without hesitation.

Rumble.

As the switch was turned on, the power system in the underground warehouse was instantly restored, the light bulbs were lit, and even the ventilation system on the roof of the warehouse was turned on, blowing a stream of air.

Li Yu quickly walked to the freezer near the door.

Push open the freezer door with both hands.

There is some water on the ground, which should have melted after the power was turned off in the past few hours, but very little has melted, and most of the walls and ground are still covered in frost.

After taking a look at the air-conditioning vent blowing out the air-conditioning, Li Yu knew that there was no problem in the freezer.

Then he walked into several other cabins and looked at the situation inside. After finding that there was no problem, he returned to the entrance.

"Send them out later and let them continue making magnetic screens. If you do more, you may be able to restore power to other areas as soon as possible." Li Yu thought for a while and said.

He knew that the geomagnetic storm was only two days old, but it would be better for the base to restore power earlier.

After Li Tie heard what Li Yu said, he expressed his understanding and left here wearing radiation protection clothing.

Then, Li Yu glanced at the warehouse and closed the door, then the second floor.

After closing the two doors of the underground warehouse, Li Yu watched the mist outside steaming. The water vapor evaporated very quickly under the sun's radiation.

Soon, water sources may face shortages.

The Dazhangshu base has always had great advantages in terms of water storage.

A deep and wide mountain pond reservoir covers more than ten acres and has a water storage capacity of hundreds of thousands of cubic meters. The reservoir at the foot of the mountain can also store tens of thousands of cubic meters of water.

There are also several small pools in the three outer cities.

In addition, there is a water tank in every greenhouse, and dozens of greenhouses store a lot of water.

There are also wells scattered throughout the base, all of which can provide water sources.

Although the reserves are large, water consumption is also large.

At present, we still need to control water consumption, and the largest area of ​​water consumption is the cultivation of crops.

The current proportion of crops grown must be changed.

At present, the main crops grown are mainly rice and sweet potatoes, along with staple foods such as corn and potatoes.

In addition to the small factor of eating habits, the biggest reason is that the soil in the south is more suitable for crops such as rice. The soil in the south is mostly acidic soil and is not suitable for growing crops such as corn that require neutral or alkaline soil.

On the contrary, sweet potatoes have become the most planted staple food besides rice.

First of all, the yield per mu is very high, it is drought and cold resistant, and its vitality is very tenacious.

Secondly, it is very convenient to plant. You can plant it by just breaking off a rhizome.

Moreover, the leaves of sweet potatoes can also be used as vegetables and are rich in vitamins.

Li Yu found Anya and said without any nonsense:

"The solar radiation is strong, and it will be difficult to replenish water sources in the future. From now on, we will reduce the proportion of rice planting and increase the proportion of sweet potatoes. This should save a lot of water."

Anya thought for a while and asked: "What kind of ratio should be adjusted to? If the rice that is still being planted now is stopped, the losses will be great. Some of them are about to enter the maturity stage."

Li Yu frowned and said:

"Aren't you using the rotation method now? Don't move the ones that have already been planted.

It’s just that after harvesting mature crops recently, when we plant again, we just need to plant all the sweet potatoes.”

"Ok, I see."

After explaining this, Li Yu put on his helmet, pulled Yang Tianlong and others, and lowered the black heat-insulating ball into the Shantang Reservoir.

After these black balls are put in, they can isolate a large part of the sun's heat, and the evaporation of water in the reservoir is also greatly reduced.

.......

Deep in Wuyi Mountain.

Four "corpses" lay there.

The best way to save food is to eat less. Lying down and sleeping is the best way to save energy.

Except for eating a little bit of food every day, they basically don't go out and lie on the wooden bed trying to sleep.
