Chapter 348 "Ultimate Shelter Project Planning"

"Hey! I'm here!!" Lu Yuan waved his hands towards the sky and shouted loudly.

Acting is also very tiring!

In order to increase the authenticity, he asked the king insect to bring him here a month in advance.

He hadn't shaved his hair for a long time, like a long-haired dog, and he hadn't washed his face for a long time, and his clothes were tattered.

The floating city in the sky was like a large kite. After discovering Lu Yuan, the whole city was in an uproar.

"Quick, land quickly!"

"Boom!" The city landed five kilometers away, raising a blanket of dust.

This area is very magnificent. The ocean in the distance has become land, and there are still large areas of red magma in some places. The average temperature is about 40 degrees Celsius.

Soon, a group of people drove large armored vehicles and ran out of the city.

"Are you all okay? Everyone!"

"Commander-in-chief, everyone has had a hard time these years! There was almost a food crisis... Fortunately, we survived." Tears flashed in the eyes of Sha Mo, Sha Kan'er and others.

Several younger generations who had a better relationship with Lu Yuan burst into tears when they saw their adoptive father, and some of them were speechless.

"Alas, you have lost a lot of weight. We still survived this disaster." Lu Yuan also sighed in his heart. Although he knew the result a long time ago, he still felt a little sad at this moment.

"This is... the result of our development! We have not stood still." Lu Tiantian rubbed his eyes and patted the crawler robot around him that was as big as an excavator, with four mechanical arms and a drill.

"Is it the technology of the Source Fire Civilization?"

"Yes, it can work in complex environments. It can resist high temperatures and cold, and has a certain degree of idealistic resistance." Lu Tiantian said some random things to hide the joy in his heart.

His tense mind was finally let go.

These years have been really hard. Lu Yuan saw it and was anxious, but he couldn't help.

But... just get through it...

Human 18 civilization has indeed matured. Some disaster response mechanisms can be done well without his instructions.

"How did you survive the disaster?" Soon, some reporters heard the good news and rushed over.

They saw Lao Lu and wiped their tears.

After Lu Yuan hugged them, he said: "First use the space ability to survive the first wave of volcanic eruptions. The explosion was really spectacular, like a star explosion."

He said the rhetoric he had made up for a long time: "Then there was a protracted war. Fortunately, I always have a lot of food and water in my storage space. I used it sparingly and I was able to survive. And... look!"

Lu Yuan showed a shiny thing - a bead for breathing underwater!

"Using this gadget, I can immerse my head in water to isolate many toxic gases. I can breathe in water."

"Another most important point is not to be defeated by loneliness."

In front of the TV station, he even boasted: "In the past six years, I have seriously studied the forging knowledge and carving knowledge of the Source Fire Civilization, and at least mastered 70% to 80% of the knowledge."

"The most important thing for a person is a strong heart and the determination to never give up."

"I know there are still many people waiting for me."

Then, Lu Yuan took out a shield-like protective equipment, which was made using the forging skills of the Source Fire Civilization, to prove that he was not bragging.

"..."

The old cat was silent. He was obviously staying in the Sky City, but he kept boasting.

Of course, this big gong and drum is also a necessary ritual for returning.

Whether it is the students in the school or the ordinary people in the society, they can't tell whether what Lu Yuan said is true or false. They are simply excited and shouting with a fanatical attitude to welcome the return of the hero, and they keep clapping.

To be honest, in the past six years, although everyone has fought against the cold disaster and made small progress, there is always a sense of awkwardness and stagnation in the operation of society.

No one knows what this awkwardness is, just like a kind of... lack of backbone?

Occasionally, someone will complain a few words? Why don't you go and rescue Lu Yuan?

Even those Zerg warriors seem to be... not so obedient... I don't know if it's a psychological illusion.

But with Lu Yuan's return, this feeling immediately disappeared.

After all, Commander Lu is not only alive, but also working hard to learn knowledge, so what can ordinary people complain about?

This situation made the rat craftsmen sigh: "This is amazing, worthy of being a man with all the luck..."

"This shield really has some technology from the Source Fire Civilization. Is he really learning?"

The rat craftsmen were a little confused. Surviving in the wilderness can actually take care of learning. Is this guy really a saint?

...

Lu Yuan was not idle. He first showed up in front of the crowd to announce that he was "still alive".

The overwhelming voice really made people feel like a fan club...

Then he took a shower to wash off the dust on his body, held a press conference, and then a dinner hosted by the government.

In fact, it was nothing unusual. Recently, some emerging scientists, engineers, etc. have emerged. According to convention, they need to be commended by the president himself. Now that it has been delayed for so many years, it must be done quickly.

Lu Yuan was mediating, communicating, clinking glasses among the crowd, and understanding the overall affairs of the city. Even if there was no wine, he could still drink tea instead of wine, and he seemed to be at ease.

"Everyone has worked hard. I have done nothing in these years, and it is all thanks to you that I have been able to survive until now. I propose a toast to you all to show my gratitude."

"May we work together in the future."

The rest of the top government officials looked very relaxed. This is a smooth civilization... Otherwise, just the redistribution of power can dismember and divide the entire civilization!

After the banquet, Lu Yuan sat at his desk. Miss Conch rolled her eyes and piled a mountain of official documents on his desk.

"Why are you rolling your eyes?"

"I just think you deserve a beating. You've come back early tomorrow, and you've been pretending to suffer for six years." The girl clenched her fist and knocked on Lu Yuan's head, making a "dong-dong-dong" sound.

Lu Yuan laughed. If a civilization wants to develop, it is normal to hide something.

How can there be so much Guang Weizheng in the world?

Even history is just a little girl who can be dressed up by others. Since everyone thinks that he, Lu Yuan, should be such a suffering character, he can only explain it this way...

"I actually spent six years surviving outdoors..."

He had long known what changes had taken place in the Sky City, but he still symbolically turned over a few pages of these miscellaneous official documents.

"Extraordinary animals and plants, their vitality is tenacious, and they have been generally protected during the cold disaster. But there has been no sunshine for six years, and the yield of plants is extremely low, so almost all talent training plans have been downgraded..." Conch said simply in a crisp voice Explained again.

"Oh, I have wasted everyone's six years of good time." Lu Yuan took a pen and signed his name on several government documents.

"Everyone has no complaints. It's good to be alive these days." Conch added, "In addition, the cold resistance project has basically been completed, and heating has been installed in every house. Water pipes and other things have also been modified. If there is another cold disaster, I won’t be so embarrassed.”

"The central shelter has also been greatly upgraded, and the fresh air system can filter most of the toxic gases."

"But no matter how we transform it, our city is not a spaceship, and it is impossible to achieve material recycling."

Lu Yuan nodded. The artificial ecosystem is another very difficult subject. So far, it is impossible for human beings to isolate themselves from the outside world and survive on their own.

"So some experts believe that an ultimate shelter must be built in the sinkhole."

This was something Lu Yuan didn't know. He frowned and asked, "How do you say it?"

The girl paused for a moment: "No matter how the shelter is designed, there are loopholes. People have to breathe and eat. As long as they have material needs, they will be affected by the outside world."

"And the proportion of time spent in the sinkhole is one percent of that in the outside world. If there is an unstoppable disaster, all the people can only hide in it and survive for a period of time. Maybe the disaster will be lifted."

"This shelter doesn't need to be too complicated. It just needs to be installed with a large number of hibernation chambers for everyone to rest inside."

"Isn't this plagiarizing the 'Original Fire Civilization'?" Lu Yuan raised his eyebrows.

"Yes... but our purpose is not to avoid the epochal disaster. For a cold disaster like this, it might be much simpler if we have a large hibernation warehouse."

Lu Yuan opened a document - "Ultimate Shelter Project Plan".

Scientists have carefully studied the "hibernation freezer" of the Origin Fire Civilization. Its hibernation principle is an extraordinary material called "cold spun stone", which can produce an idealistic gas and put humans into a state of hibernation.

The quality of these hibernation freezers is quite high and can reduce the body's metabolic rate to one ten thousandth of normal conditions.

In the hibernation state, the breath of life emitted is naturally very small and difficult to be discovered by external enemies.

So people plan to dismantle some materials and imitate them by making some hibernation freezers with slightly lower quality.

The hibernation barn occupied by one person is not very large. It is 2 meters long, 1 meter wide and 0.5 meters high. It only takes up about 1 cubic meter of volume.

Even if there are 1 million people, there will only be 1 million cubic meters of freezers.

The internal space of the Dinh Lai Empire spaceship carrying the [Ghost] is not small, and it is more than enough to fit these hibernation cabins.

"Inexplicable idea, are you going to keep company with [ghosts]?"

"Even if the [ghost] hasn't escaped the seal yet, there's no need to do this."

Lu Yuan frowned and thought for a while. At first, he felt it was not appropriate.

But I feel like... it's really necessary...

After all, this is the final trump card.

The ecological environment of this world is really fragile. The volcanic ash in the sky caused a nuclear winter for six years and caused cold disasters.

God knows what weird disasters will happen in the future.

As for the Dinalai Empire's spaceship, its protective performance is quite good, and there are some defensive glyphs on it that humans cannot decipher.

If you ignore the [Ghost], it's really a good place to take refuge.

"You really need to think about it..."

At eight o'clock the next morning, Lu Yuan worked hard all night, quickly approved most of the documents, and held a simple meeting.

Well, after so many years of busy work, Lao Lu, the backbone, reappeared. At the first upper-level meeting, everyone was quite excited, and everyone was very excited.

"I've seen the ultimate shelter plan...how long is it expected to take? How much will it cost?"

Professor Sha Mo of the College of Engineering said immediately: "The difficulty of that project is not great. As long as the spacecraft is equipped with the Pandora crystal power system and a few doors, this large spacecraft can be used as a sky fortress."

"And the quality of the hibernation chamber does not need to be very high. After all, we don't rely on it to survive the epoch disaster, so only one-tenth to one-twentieth of the materials are needed."

"Including the hibernation of animals, a 500,000-yuan freezer will cost 1,500 Lingyun materials, mainly cold cotton stone."

"If the future population growth is taken into account, some hibernation chambers may need to be added. Anyway, no more than 2,000 Lingyun."

Lu Yuan raised his eyebrows. You really spend money like water. 2,000 Lingyun materials would have cost you your life in the past! Only now that I have some money can I barely afford it.

But no matter how I think about it, I feel...

It is still necessary.

The key is to be alive. Death is worthless.

"Okay, I have no objection to this matter..."

"If there is anything special, report it together, and then start working early."

Lu Yuan suddenly thought of something and reported to everyone how the Mirage Dragon survived the epoch disaster.

Of course, he concealed the existence of the "Chaos Essence Stone" and only said that there was a mysterious "White Jade Hall" at the bottom of the magma, which was a relic of the gear civilization.

"Under the impact of the magma, the White Jade Hall was directly ejected into the sky! This building could not withstand the power of the earth and collapsed and shattered directly."

"And I used the alien space to protect myself at the moment when the hall was broken. In the end, I only got this little thing and a copy of the "Gear Treasure Book" inheritance."

Lu Yuan took out a few gears and a wall made of white jade.

The materials of these things are ordinary, just ordinary stones, but the micron-level and even nano-level carvings really surprised everyone, and they can be described as magical.

"This "Gear Collection" is really exquisite. I have studied it for six years, but I can't get started... I am really ashamed."

Theoretically, the idealistic existence of carvings can only be engraved manually.

But how much engineering work is required for micron-level engineering, even for just a gear?

This is obviously not made with traditional skills.

So this inheritance cannot be taken on by Lu Yuan alone, it requires the wisdom of the entire civilization.
