"Hey! I'm here!!" Lu Yuan faced the sky, waving his hands 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.

I haven't shaved my hair for a long time, like a long-haired dog, I haven't washed my face for a long time, and my clothes are in tatters.

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

"Hurry, land quickly!"

"Boom!" The city landed five kilometers away, kicking up overwhelming dust.

This area is very majestic. The ancient ocean turned into land, and large areas of red magma still remain in some places. The average temperature is about 40 degrees Celsius.

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

"Are you okay? Everyone!"

"Commander, we have all had a hard time these years! We were almost in a food crisis... Fortunately, we survived." Sha Mo, Sha Kan'er and others had tears in their eyes.

Several juniors who had a good relationship with Lu Yuan burst into tears when they saw their adoptive father, and were actually speechless.

"Oh, you have also lost a lot of weight. We still survived this disaster." Lu Yuan also sighed in his heart. Although he had known the result for a long time, he was still 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 nearby crawler robot as big as an excavator, with four robotic arms and an earth drill.

"The technology of the Origin Fire Civilization?"

"Yes, able to work in complex environments. Resistant to high temperatures, cold, and a certain degree of spiritual resistance." Lu Tiantian said a few words to cover up the joy in his heart.

His tense mind finally let go.

It has been really hard these past few years. Lu Yuan saw it in his eyes and was anxious in his heart, but he couldn't do much to help.

But... just get over it...

Human civilization has indeed matured, and everyone can do some disaster response mechanisms very well without him having to order them.

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

When they saw Lao Lu, they all wiped away tears.

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

He talked about the story he had been making up for a long time: "Then there will be a protracted war. Fortunately, I have a lot of food and water in my storage space. I use them sparingly, so I can survive. And... you see!

"

Lu Yuan showed a shiny thing - a bead that breathes underwater!

"Using this gadget, I can isolate a lot of toxic gases by immersing my head in water. I can breathe in the water."

"The most important thing is not to be defeated by loneliness."

In front of the TV station, he even boasted: "Over the past six years or so, I have carefully studied the forging knowledge and glyph knowledge of the Origin Fire Civilization, and I have mastered at least 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 many people waiting for me."

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

"..."

The old cat was silent, obviously staying in the Sky City, bragging endlessly.

Of course, the loud gongs and drums are also a necessary ritual for return.

Whether it was students in the school or all living beings in society, they could not tell whether what Lu Yuan said was true or false. They just shouted excitedly and kept shouting with a fanatical attitude to welcome the return of the hero.

applaud.

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

No one knows what this jerkiness is, it's like...a confusion that lacks a backbone?

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

Even those Zerg warriors seemed to be... less obedient... I don't know if it was a psychological illusion.

But as Lu Yuan returned, this feeling immediately disappeared.

After all, the commander-in-chief of the mainland is not only alive, but also working hard to learn knowledge, so what do ordinary people have to complain about?

This situation made the rat-man craftsmen sigh: "This is so amazing, he is indeed a man who has the whole destiny..."

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

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

…

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

The overwhelming sound really makes people feel like a fan...

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

In fact, there is nothing unusual. Recently, some budding scientists, engineers, etc. have appeared. According to the custom, the commander-in-chief needs to personally commend them. Now that it has been delayed for so many years, it must be done quickly.

Lu Yuan was mediating among the crowd, communicating, clinking glasses, 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 Guangweizheng 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 once.

"Alas, we have wasted six years of our 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 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 external ecology 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."

"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 may be much simpler if there is 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 to make 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 interior space of the Dinh Lai Empire spaceship that carries the [Ghost] is not small, and it is more than enough to fit these hibernation cabins.

"Inexplicable idea, do you want to keep company with [ghosts]?"

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