Apocalypse: I built the Supreme Sanctuary a year in advance

Chapter 20 Power Supply Crisis
Space is scarce in the space station, so an air circulation system is the best choice for them.

But Xu Zhengyang’s shelter is not a space station.

The last thing he lacks here is space!
So Xu Zhengyang, who had gotten out of his dilemma, immediately rushed out of the shelter and drove towards the Baicheng Flower and Bird Market!

*
Two hours later.

Xu Zhengyang's car was driving in front, followed by a small truck with a full cargo bed.

After the masters finished unloading the goods, Xu Zhengyang sent them away.

Only then did Xu Zhengyang use the dimensional space bag to move the green ivy and plant lights unloaded by the masters into his own shelter in batches.

Pothos is a very easy plant to grow.

As long as the temperature is suitable, there is no lack of water, and it gets some sun every day, the green ivy can easily grow from a small pot to a large pot!

And even if you accidentally kill it.

Just pick a piece of green ivy vine and put it in the flowerpot. It won’t take long before a large pot of new life will grow. Its vitality is so tenacious!
*
Inside the shelter.

Xu Zhengyang first asked the engineering robot to use the leftover scraps from previous work to build a metal shelf in the living room.

Then put the green radish together and install plant lights above them.

Wait until all this is done.

Xu Zhengyang turned on the plant light and used the handheld pump-type oxygen O2 gas alarm he had just bought to test the oxygen concentration nearby.

As time goes by.

really!

The oxygen concentration around the pothos rack began to gradually increase!

Xu Zhengyang was very excited when he saw this.

Then he immediately operated the engineering robot to pour concrete into the previously reserved ventilation holes!
The engineering robots were busy, and Xu Zhengyang was not idle either.

Just having a pothos rack that produces oxygen is not enough.

Xu Zhengyang also needs to monitor the content of air components in the shelter at all times to adjust the brightness control of the plant lights to ensure the air safety in the shelter.

at this time.

The Shelter Control Center that Xu Zhengyang received as a reward for the [Decoration] mission can finally be put to good use!

First, use the installed fresh air system to ensure air circulation in the shelter;
Then place air composition sensors at various locations in the shelter;

Finally, all the data is combined to allocate power to the plant lights to ensure that the oxygen concentration in the shelter can always be maintained at 20%.

Just after Xu Zhengyang set up the air circulation in the control center.

His engineering robots also happened to block all the reserved air circulation vents in the shelter.

Just now.

The biological air circulation system that Xu Zhengyang built in his own shelter finally started to operate normally!

And he finally completed this difficult time-limited challenge!
[Limited-time challenge mission: Airtightness modification (completed)]

[Warning: Please find a space no smaller than 5m*5m*8m to claim your mission reward!]

As the task prompt appeared, Xu Zhengyang was very excited!
With the GX-2 large-scale engineering robot, Xu Zhengyang can fully use his robot to complete the main task of this expansion!
So Xu Zhengyang immediately controlled his GX-1 engineering robot to the northwest corner of his shelter, transformed it into a drilling vehicle and began to dig down.

Xu Zhengyang planned to dig a second underground floor under his shelter, turning it into a giant space 300 meters long, 300 meters wide and 5 meters high!
Although the walls of Xu Zhengyang's shelter are made of C120 concrete mixed with fine copper wire.

But even this reinforced concrete wall, which is strong enough to withstand artillery shells, cannot withstand the impact of the GX-1 engineering robot in drill form!
"With an engineering robot here, I can even drive it into the bank's vault, haha!"

Xu Zhengyang said this casually, then set an automatic digging program for the engineering robot and went out again.

He needs to buy some concrete, thin copper wire, electrical wires, PVC pipes and other building materials.

After all, the area of the second underground floor is so large, and the various building materials needed are not a small number!

*
It was already six o'clock in the afternoon when Xu Zhengyang returned home.

This time, Xu Zhengyang returned to his sawmill with a semi-trailer full of C120 concrete.

Not only that. There was also a truck crane following behind the semi-trailer, which was specially used to help Xu Zhengyang unload the goods!

So much concrete.

If there was no truck crane to help unload the goods, it would take at least a whole day to do it by manpower alone. Xu Zhengyang didn't want to waste time on such a trivial matter.

Just when the semi-trailer was unloading.

Other building materials purchased by Xu Zhengyang, such as thin copper wire, electrical wires, steel bars, PVC pipes, etc., were also delivered to his door one after another.

Fortunately, Xu Zhengyang’s sawmill is large enough, otherwise it would not be able to accommodate so many delivery trucks!
Just when a large group of workers were busy unloading goods in Xu Zhengyang's sawmill.

Sudden.

Just listen to a "pop" sound.

All the high-powered searchlights in the sawmill went out at once!
It's already half past eight in the evening.

Baicheng is located in the northwest.

In mid-November, it was dark enough at this point to see the stars.

Therefore.

As soon as the power went out, the workers who were unloading the goods stopped their work and said to Xu Zhengyang:

"Boss, the power outage occurred!"

"Is there an electrician? Let's get an electrician to change the fuse. Otherwise, it's so dark that we can't do our work!"

……

Xu Zhengyang was also very surprised.

Because his sawmill uses industrial circuits, when the factory was running at full capacity, it was more than enough to handle twenty large woodworking machines.

Why are some lights tripping now?
So Xu Zhengyang immediately went to the distribution box to check.

really.

It's a power outage, not a circuit breaker.

So Xu Zhengyang hurried back to the shelter, took out the diesel generator he had bought earlier, connected it to the circuit and started it up.

After the searchlights came back on, the workers continued to work.

Xu Zhengyang finally had time to call the power supply bureau:

"Why is there a power outage on Beisi Road?"

……

moment.

Xu Zhengyang hung up the phone with a grim face. From today on, his sawmill would have no electricity!

According to the explanation of the power supply bureau.

The demolition agreements for this large area in the northern suburbs have basically been negotiated, and the first phase of demolition has already started ahead of schedule from North First Road.

So start today.

In accordance with the spirit of the superior documents, the Power Supply Bureau has stopped power supply to all factory areas outside the northern suburbs residential areas!
When the GX-1 engineering robot is running at full capacity, it requires kilowatts of electricity per hour.

The GX-1 large-scale engineering robot, which is more advanced than the GX-2, may require twice as much electricity to operate!
but now.

The power supply bureau cut off the power supply to all factories in the northern suburbs.

Xu Zhengyang's two engineering robots were no different from two pieces of scrap metal.

"Ugh……"

Xu Zhengyang sighed and rubbed his temple helplessly, "I have to find a way to solve the electricity problem..."
