The world of shelter under the glacier

Putting down his depressed mood, Chu Feng patted his face and cheered up.

Vukong bowed earnestly, and first prayed before buying a lottery ticket, "The sky is full of gods and Buddhas, the Jade Emperor, Tathagata Buddha... Guanshiyin Bodhisattva, please give me divine light... you must bless me, Winning a jackpot!”

As soon as he finished speaking, Chu Feng shouted loudly: "Receive the gift bag."

"Beep, the gift pack is being randomly generated..."

"Beep, it has been generated."

"Hey, please choose three of the following six items."

Immediately, six items appeared in Chu Feng's field of vision, shining brightly and dazzlingly.

"Which one should I choose?"

1. One steam and diesel hybrid generator

2. One low-profile biological oxygen generation device

3. One pack of high-end toilet paper

4. An electromagnetic pulse cannon

5. A signal stabilizer

6. A vent modification talisman

Looking at these 6 items, Chu Feng was in a dilemma - "I want them all, Brother System, no...Dad, is that okay?"

Chu Feng wasn't angry when he didn't get a response from the fool-like system.

The reason is that since Chu Feng got the system, he bombed it whenever he thought of it. He struggled for more than a month, but the system never responded.

"Used to it!"

After complaining, Chu Feng calmed down and read the text descriptions of the items one by one.

For this rare opportunity, Chu Feng must choose carefully.

According to the information passed in by the system, on the first day of every month in the future, the system will have such a gift package for Chu Feng to choose from.

However, in the future, the gift packs that appear every month will not be so rich, there will only be 2, choose one.

There are so many today only because the binding gift pack and the April gift pack are combined into one, so the result of choosing 3 out of 6 appears.

Opportunity - it's really rare!

"When things are uncertain, our ancestors have their own teachings - let's do some elimination first."

Chu Feng thought to himself.

"Then let's eliminate item 3 first, toilet paper. What the hell is high-end?"

"If this could last a lifetime, I would choose you right away without even thinking about it. After all, all plants will die in the apocalypse, and in some places it is really hard to find a piece of paper."

He looked at his fingers and said, "I hope this won't happen..."

Chu Feng shivered inexplicably.

"Then there's the electromagnetic pulse cannon."

"One, there's no energy to supply this big guy."

"As for the second one...is it still necessary? This reason alone is enough."

After scratching his head, Chu Feng was really in a dilemma - the remaining four items were of great use.

······

Chu Feng looked back and forth carefully, and carefully compared them one by one with the existing equipment in the shelter.

Take a deep breath.

Chu Feng said solemnly: "Don't be afraid! I still have the second magic weapon left by Taizu - choose the most needed one first."

"First of all, we must know that the oxygen concentration can only be between 5% and 5% for humans to live normally."

"But in the future, the oxygen concentration in the air will be rapidly depleted due to global fires, dropping to 10%. If the human body is exposed to this environment for a long time, even if it is mild, it will cause purple lips, shortness of breath, and loss of judgment. and other symptoms; in severe cases, various symptoms such as paleness, nausea and vomiting, and even fainting, complete loss of intelligence, etc.”

"There's nothing better than killing someone invisible!"

"So, the oxygen generator must be the first choice. After all, you can't lack oxygen if you don't have anything. If a person doesn't have oxygen, he will burp immediately."

"Secondly..."

Thinking of the strong magnetic field crisis caused by meteorites, communications between various places on Aquamarine were seriously affected, and each shelter almost became a doomsday boat.

"In such a bad situation, although I don't know how effective the signal stabilizer can be, there is still hope, right?"

"If it can really work, we don't need 3,000 miles, but 300 kilometers is acceptable. It can completely cover the entire southern Anhui Province."

"Then with the advantage of communication, won't the doomsday trading market I planned take off and take off?"

Waving his hands excitedly, Chu Feng said with a smile: "I chose, I chose!"

Look at the [Hybrid Generator] on the left and the [Vent Modification Talisman] on the right.

Chu Feng was stuck again.

Both devices are available in the shelter, but their performance is far different.

"If you choose a generator, you can save half of the fuel every month. This will double the time the shelter can last. If you stay there for such a long time, you can save enough shelter points to upgrade equipment."

"But the vent modification talisman is also very powerful. I like it very much..."

For a while.

Chu Feng seemed to be comforting himself and said softly: "Since I have chosen the oxygen generator, the air is enough to meet the needs of 5 people."

"As for the smoke and dust, I will upgrade the vents according to the situation."

Having made up his mind, Chu Feng no longer hesitated and said solemnly: "For the system, I choose [gas and diesel hybrid generator], [low-end biological oxygen generation device], and [signal stabilizer]"

"Beep, it's manifesting, please wait..."

"Beep, the realization is complete."

"Please select a storage location."

Chu Feng pointed at the corner of the warehouse and said, "Just put it there."

The words just fell.

The space was distorted.

Unexpected.

Chu Feng saw three machines appearing in the open space inexplicably.

"Is this a direct plunder and teleportation? Does the master agree?"

"Or was it copied through a mirror?"

pity.

The system did not respond to this.

"Forget it... Maybe I won't understand how this system works for the rest of my life."

When I thought about it again, I realized that I was just full and had nothing to think about.

Do you need to know how to make the cars you drive, computers, refrigerators, washing machines, etc.?

As long as you can use it.

Similarly, the system only needs to quietly act as its tool and assist itself properly.

At least he didn't issue any tasks to pressure himself.

A little simpler is acceptable.

I believe that through your own efforts, you will be able to DIY an extraordinary shelter.

even.

Who says shelters can only be built underground, can they not be built in the air?

The city in the sky is not a dream!
