It's none of my business. I'm just a lunch box seller.

"It's the same for us now." The official of Xin Chang'an smiled and said, "The only difference is that we have passed the most difficult period of starting from scratch and the initial construction stage when everything was in ruins. Now our motherland and underground city are thriving and full of hope."

After saying this, the middle-aged official from New Chang'an stretched out his hand and introduced himself: "My name is Ai Jianshe, and I'm the city manager of the New Chang'an Underground City."

The term "city leader" is a very euphemistic one. If it is replaced with another more understandable title, it would be the mayor of the capital city!

0211 I don't care

The new Chang'an underground city is very large, even surprisingly large.

Although the original Ordos mines were not as large as those in Daye and Fushun, there were still countless hollowed-out mineral layers deep underground in the basin.

Therefore, the underground city of New Chang'an is not simply funnel-shaped as Boss Cheng thought, but an underground city network with the funnel-shaped underground city as the main body, extending in all directions.

The main funnel-shaped underground city of New Chang'an has a total of 21 floors, divided into 4 floors above ground and 17 floors underground. The first floor of the above-ground part is the train station and parking lot, as well as a super-large machine repair workshop, with a height of about 1 meters. The heights of floors 20 to 2 are fixed, each 4 meters high, and are mainly used for atmospheric monitoring, communications, and for arranging work that cannot be done underground.

The underground part is divided according to function, with floor heights ranging from 10 to 18 meters.

The underground city area with the largest single-layer area is located between the negative 1st and negative 3rd floors. The two sides of the top floor are industrial areas with a floor height of 18 meters. There are various factories in the two floors. If divided by industry type, the negative 1st floor belongs to the heavy industry area, while the negative nd floor is the light industry area.

As for the negative 18rd floor, which is also 3 meters high, it is the base of the underground city troops, as well as the storage warehouse for weapons, ammunition, important supplies and food. Ordinary residents are prohibited from entering the negative 3rd floor area without permission.

The minus 13 to minus 17 floors are the office areas for the government and the military. Because this is the farthest from the ground, it is the safest area in the entire underground city. And when this underground city was first designed and built, the nuclear reactor was placed far away from the underground city. After all, no one wants the entire underground city to be like Chernobyl because of a problem with the reactor.

The negative 4th to negative 12th floors are residential areas, with a floor height of 12 meters. All the buildings on the floors are standard 2.77-story residential buildings with a height of 4 meters. These buildings are not only the homes of the residents of the underground city, but also bear the overall load-bearing and support responsibilities of the underground city.

Of the nearly 50 residents registered as residents of New Chang’an, less than 40% live in the main nine-story residential area. The remaining 9% are distributed in the mesh “outer ring” area outside the main part of New Chang’an.

That’s right, the funnel-shaped underground city of New Chang’an is equivalent to the East City and West City districts of the old capital, and other places belong to the “outer ring”.

As for why it has been more than 200 years since the nuclear war, but the number of residents in New Chang'an is only "a mere" 50.

The mayor of Xin Chang'an told Boss Cheng and his staff, "Because in the first hundred years after the nuclear war, everything had to start from scratch, and it was difficult for grain seeds to grow normally in soil containing trace amounts of radiation. So in the first hundred years after the war, we have been committed to rebuilding the industrial system, improving grain varieties, and striving to expand the scale of grain production.

100 years later, our living conditions have been greatly improved. Efficient logistics networks have been rebuilt between underground cities, and large underground cities have begun to build satellite underground cities in surrounding areas to share the upcoming population pressure of large underground cities.

We have already started to prepare for our return to the surface. We estimate that by 2350, we will be able to reduce the cost of radiation neutralizers to a bargain price. By then, all Chinese people will set foot on Chinese soil again!"

However, the UNSC staff fell into silence after hearing the term "radiation neutralizer". At first, Boss Cheng didn't understand, but when Zhou Zhezhi told Boss Cheng that Dr. Ji, who died at the time, was an authority on the half-life of radioactive elements and had been committed to the research of anti-decay.

"Anti-decay?" Boss Cheng asked in surprise.

"Very sci-fi, right? But Dr. Ji Yuehua is an authority in this field of 'sci-fi'!"

Suddenly, the mayor of Xin Chang'an was shocked and asked Zhou Zhezhi: "Did you mention the name Ji Yuehua just now?"

Zhou Zhe nodded and replied, "Yes, is there anything wrong?"

"No, there is nothing wrong with it." The mayor immediately explained: "The technical principle of the radiation neutralizer we have mastered originated from the research of Dr. Ji Yuehua."

In other words, there was once a nuclear physics doctor named Ji Yuehua in this world who was also dedicated to the research of anti-decay. Dr. Ji's research path was even more far-reaching than that of Dr. Ji who died.

The mayor also told Boss Cheng and his team that Dr. Ji and his colleagues have been working hard for more than 200 years to find ways to slow down the decay of radioactive elements.

"This lineage of theirs has remained in the old Iron Dome underground city of the original Fushun Mine."

"Lao Tieqiong?" Upon hearing this name, Boss Cheng immediately flew into a rage and cursed: "What the f*cking era is it now? Why are you still doing this bullshit of regional discrimination? And the government is leading the way!"

When the mayor heard that Boss Cheng had misunderstood his meaning, he quickly explained to him:

"It's not that Lao Tie is poor, but the old Iron Dome Underground City. The super underground city in Fushun Naga was originally called Iron Dome, which means the steel sky. But more than 50 years ago, the geological survey team of the Iron Dome Underground City discovered a high-grade iron ore deposit that had never been explored before, 3000 meters underground, in the north of Hualin City.

Then they dug out a small underground city with a capacity of 5 people nearby and named it the New Iron Dome. Since there is a New Iron Dome, the original Iron Dome automatically becomes the Old Iron Dome! So this is not the official leading the way in regional discrimination, but pure coincidence.

In addition, the old Iron Dome relies on various industrial technology universities in the former Northeast, plus the long industrial tradition of the Northeast. Looking at underground cities across the country, the level of technological development of the old Iron Dome cannot be said to be among the best, but it can only be regarded as the best!

Just two years ago, they launched a carrier rocket into low-Earth orbit to observe radiation levels in various regions across the country. Although the rocket was successfully launched, the observation satellite lost contact after entering orbit. In the past two years, they have been looking for the cause of the failure, and plan to work hard to build a rocket after finding out the cause. "

"You mean the old Iron Dome not only built a launch vehicle but also launched it into space?"

"Yes." The mayor nodded.

"After the satellite was launched by the rocket, it lost contact instantly?"

"Yes." The mayor nodded again.

"The observation satellite they launched was shaped like a large iron box sandwiched between two solar panels, with a pot lid on the front?"

The mayor simply thought about it and nodded repeatedly. But as soon as he nodded, he realized that something was wrong, and he hurriedly asked Boss Cheng: "How do you know what the observation satellite looks like?"

"Oh, I saw a similar satellite in the trophy warehouse of the Zeta spacecraft when I was killing aliens on it. The satellite should still be in the trophy warehouse of the Zeta spacecraft. Why don't I send it back to you when I have time?"

New Changan Mayor:!!!∑(?Д?ノ)ノ

Later, the mayor of Xin Chang'an learned from Zhou Zhezhi about the existence of the Zetas and the news that the Zeta fleet almost conquered the earth. But most importantly, the mayor learned the truth about the nuclear war that broke out that year from Boss Cheng and Zhou Zhezhi!

Soon after, the boss and the UNSC staff were taken to the underground city's negative 17th floor, which was the lowest floor of New Chang'an. In a private meeting room here, an old ghoul was waiting for everyone to arrive.

At first, everyone was still unclear about the old corpse ghost's identity and the purpose of his coming here. However, when the old corpse ghost introduced himself, everyone realized that the person sitting opposite them was the last Prime Minister of the Fruit Ministry before the outbreak of the nuclear war!

And this Prime Minister happened to be the person in charge of our side who attended the armistice negotiations that year!

After he learned the truth about the sudden nuclear war, he sneered a few times, and then recalled leisurely: "I remember that when the nuclear war broke out, we were all at the negotiation table. At that time, the armistice agreement between the two sides was about to be reached, and we and the US side were even discussing the time and place for the formal signing of the armistice agreement.

Then, the US Secretary of State and I received news of the outbreak of nuclear war from our respective countries almost at the same time. Until now, I still remember the shock and astonishment on the face of the US Secretary of State when he learned that his country had launched a nuclear bomb first. "

"Pah! Crash..."

The water cup fell to the ground, breaking into hundreds of sparkling pieces of glass that splashed everywhere.

"We! In order to secure a future for both sides! We talked and then argued, then talked again! Over and over again for more than half a year! We were clearly! Clearly, we were only one step away from peace! All we needed was an agreement that would take effect upon signature! But, it happened! But, it happened! But, it happened!"

"Pfft!"

The old man was so angry at the despicable behavior of the Zetas that he collapsed, but even after he collapsed, he kept muttering curses against the Zetas. As an experienced old politician, he was not only angry, but even to the point of swearing, which shows the resentment in his heart.

But Boss Cheng and his friends didn't know that for more than two hundred years, the old man had been living in deep self-blame. He regretted why he couldn't finalize the armistice agreement a few days earlier, and why he argued endlessly over the signing time and place.

But it was not until this moment that the old man realized that no matter how the two powers talked and to what extent, the Zetas would trigger a global nuclear war on their behalf. The two once invincible powers were fooled by this group of alien bastards called Zetas!

Fortunately, "Zeta" has completely become a historical term. Even the old man believes that Boss Cheng's act of killing the Zeta people is not only revenge for the past deaths, but also a hero who saved the earth.

At the end of the meeting, the old man also made it clear: "No more fighting! No more fighting! There is no need to fight anymore! For a very long time to come, we must invest all our resources, time and energy into restoring productivity and continuing to improve the quality of life of the people. As for the Americans' constant concerns about whether we will counterattack or other similar ridiculous ideas, you might as well pass on a message to them on behalf of the organization."

"Just tell them straight, we don't want that piece of shit in North America!"

0212 Lost Cultural Treasures

"The sun is aging rapidly? Only 50 years left? Helium flash!"

Helium flash!

The administrative and military leaders of the New Chang'an Underground City felt dizzy. They couldn't understand why the sun, which had been revolving around the earth for 45 billion years, suddenly stopped working.

If the act of dropping nuclear bombs on each other is like flipping a table, then a helium flash disaster is like blowing up a house! Or the kind that happens when the doors and windows are sealed and the whole family is trapped in the house.

The news about the "helium flash" could not fail to alert the New Chang'an. But they were not alerted to the invasion of the UNSC, but to the fact that the sun above their heads would suddenly...

"Please rest assured about this." The UNSC team leader quickly gave them a heads-up, telling them, "We have visited several worlds, and it seems that the one we live in is the most unlucky. The shortest countdown to our destruction is only 50 years. Of course, if you are really worried, we can provide you with all the observation and detection reports on the rapid aging of the sun free of charge."

The leaders of New Changan could not help but fall into deep thought.

If we add 2024 plus the shortest 50 years...

2074 years!

Or maybe 2077 or 2078!

When the number 2077 was read out, everyone thought of not "Cyberpunk", but October 2077, 10 (Eastern Time 24) - Doomsday!

Two worlds with the same origin fell into the crisis of destruction one after another within less than 5 years! Everyone had a question in their mind - is this God's will?

"Whether this is God's will or not, none of us know." Boss Cheng suddenly smiled and told everyone in Xin Chang'an: "But we are ready to run away with the little broken ball!"

"Running away with a little broken ball?"

"That's right!" The team leader smiled at Boss Cheng, and then replied: "We at UNSC are working on all the work to take the Earth out of the solar system."

Take the Earth out of the solar system!

"hiss!"

Everyone in Xin Chang'an couldn't help but gasp. They thought, if anyone is more ruthless, then they are the ones who are more ruthless. They originally thought that the plan to eliminate nuclear pollution in East Asia within 50 to 70 years was bold enough. But they didn't expect that at this moment someone said to them:

"We are planning to use the Earth as a spaceship. Isn't that bold?"

Very bold? If you were a little bolder, the earth would be full!

However, New Changan expressed their understanding and approval. After all, given the same origin and the same life-threatening nature, it was not surprising that they could come up with such a plan when they were pushed into a corner. It could even be said that...

"We think your plan makes sense!"

As soon as these words were spoken, the atmosphere between the two sides suddenly became cheerful.

After that, the UNSC would conduct a technical exchange session in the second half of every meeting.

Zhou Zhezhi took out the 27-inch folding PDA he carried with him. But Boss Cheng didn't understand how the manufacturer could have the nerve to call this thing a "palmtop computer" when it was 27 inches when unfolded.

Whose palm has a diagonal length of 27 inches?

The accompanying technical experts showed the drawings of the super-strength load-bearing structure of the end-world-level city to the new Changan. Then there was the performance analysis of the hard titanium alloy and the industrialized production plan that will soon be mass-produced. Then there was the water catalytic system that was studied but could only be processed by CNC, and the matching hydrogen-oxygen internal combustion engine.

Finally, the highlight of the Mountain Moving Project is the super planetary engine that reaches over 2 meters! Although the heavy nuclear fusion system in the design drawings is not yet perfect and needs to be debugged and improved constantly, the engine support structure drawings of the hard titanium alloy combined with the super-strong load-bearing structure have completed 4% of the framework design work.

Experts from New Chang'an said that the UNSC in 2024 had completely surpassed them in the fields of industry and engineering more than 200 years later. Even if they looked at the UNSC's industrial engineering technology from the perspective of 2070 before the war, it was enough to make them look up to it.

But Xin Changan also has its own proud technology - underground city! And it is a mature technology that has been continuously tried, improved and verified for more than 200 years!

You know, building an underground city is not as simple as piling up reinforced concrete to build a house buried underground. Its structural layout, water supply and drainage system, ventilation and air filtration system, fire prevention and disaster prevention system, isolation and blocking system are not built overnight.

Especially when it comes to geological disasters such as earthquakes and volcanic activities that can pose the greatest threat to the underground city, or even a catastrophic disaster, the underground city has paid more than a dozen huge sacrifices before summarizing the technology of large underground cities that can withstand earthquakes of magnitude 8.0 and small underground cities that can withstand earthquakes below magnitude 8.5.

As for how to deal with a super strong earthquake of magnitude 9 or above, the method is actually very simple. Since there are so many places across the country where you can dig large pits, why do you want to dig pits in a strong earthquake zone to bury an underground city? If you really build it, you really need to have a good discussion. Are you planning to bury the underground city or the residents in the underground city?

The UNSC's staff and experts were not only optimistic about the underground city technology of New Chang'an, but also appreciated the concepts and measures on disaster prevention and mitigation. Then, the two sides naturally moved from the technology demonstration stage to the secret transaction stage.

Boss Cheng was not interested in this content. Instead of listening to their bargaining, he would rather let Xin Changan's "tour guide" accompany him to the upper residential area. He had already stopped the "tour guide" to say that many areas of the underground city are open 24 hours a day. In other words, even if it is almost midnight, there must be restaurants in the upper area open!

then……

"Sizzling enoki mushrooms 12 yuan, stir-fried shiitake mushrooms 11 yuan, mushroom egg drop soup 15 yuan, crispy shrimp 20 yuan, stir-fried chicken nuggets 28 yuan, scrambled eggs with tomatoes... 45? Stir-fried green beans 60! Roasted eggplant 66! Stir-fried beef with chili peppers 108!"

Boss Cheng pointed to the 108-piece fried beef and showed it to the "tour guide", who replied succinctly: "There are not enough cows, and the feed-to-meat ratio is too low. The main source of protein in my dungeon is insect protein, chicken and eggs."

Boss Cheng pointed at the menu and asked again: "What are those dry shrimps? They can't be cockroaches!"

The chef at the state-owned snack bar answered the question for the tour guide. He said, "Dry shrimp are grasshoppers, not cockroaches. Although some people like to eat fried cockroaches with seeds, cockroaches are usually mixed with rice husks to make chicken feed."

"Oh!" Boss Cheng pouted, as if he had learned something new. "Give me a plate of crispy shrimps and two bowls of mushroom noodles with sauce."

"Give me two bowls too."

Boss Cheng turned around and saw Zhou Zhezhi and his tour guide following him. Zhou saw Boss Cheng's eyes full of curiosity and explained to him: "They talked too much and there was nothing for me to do. I'm just a clerk, not a consultant, and they don't need me. So I came out to find something to eat."

Boss Cheng put the menu in front of Zhou and asked him to order two more dishes. He even lied to Zhou and said, "Fried female cockroaches, their specialty, do you want to try it?"

Afterwards, Cheng received Zhou's look of "I don't trust you". However, Zhou also noticed the problem of the extremely expensive stir-fried beef on the menu and the fact that 70% of the dishes had mushrooms.

Putting aside the fact that beef is extremely expensive, it is not difficult to understand that the main "vegetables" in the dungeon are mushrooms. After all, mushrooms do not require photosynthesis and have a short production cycle, making them very suitable for the residents of the dungeon to supplement vitamins and amino acids.

The reason why fresh vegetables are expensive is easy to understand. After all, vegetables need light to grow and their growth cycle is longer than mushrooms. Moreover, most of the land above their heads is used to grow food crops, so there is not much land left for vegetables.

But it’s better to have vegetables than not have them! What’s more, you can still see fruits in the underground city of New Chang’an! Even if you have to buy vegetables and fruits with tickets, being able to buy them is 10,000 times better than some durian-flavored dried earthworms!

"Earthworms?" The snack bar chef glanced at Zhou Zhezhi who asked the question and told him, "Earthworms can only be used to extract protease. The residue after extraction is fed to chickens together with cockroaches."

Hearing this, Zhou Zhezhi kept pointing at the boss with his finger, frowning and scolding him: "Cheng Tianyan, Cheng Tianyan, last time you tricked me into eating chili peppers, we haven't settled the score yet, and today you want to trick me into eating female cockroaches! How can you be so mean? You have so many bad intentions, aren't you afraid that you won't be able to sleep at night?"

Boss Cheng shrugged and said, "I am heartless and fall asleep as soon as I touch the pillow. My sleep quality is very high."

Fortunately, the chef served the dishes quickly. When four bowls of mushroom sauce noodles were served, the two tour guides picked up the noodles and ate them with relish. However, after taking a small bite, Boss Kecheng and Zhou Zhezhi frowned at the same time.

Boss Cheng tasted the flavor in his mouth and whispered, "It only tastes like salt, sauce, and monosodium glutamate."

"There's no sweetness to enhance the flavor. It seems that sugar is also a scarce commodity here."

Boss Cheng nodded in agreement and continued in a low voice: "Not only sugar, there is no spice at all."

Zhou Zhezhi guessed: "I guess all the underground cities are trying their best to ensure the safety of food production."

Out of respect for the food, the two of them gritted their teeth and finished a bowl of noodles that was larger than the bowl of cold noodles. For Zhou, who was used to Boss Cheng's cooking, this bowl of noodles had no other taste except saltiness and the earthy smell of mushrooms. Only the aroma of the fried insect protein could suppress the unpleasant smell of the mushrooms.

However, the two "tour guides" regarded Boss Cheng and Zhou Zhezhi's behavior as being spoiled. They didn't know that even without spices, Boss Cheng's cooking skills alone would make food much better than that of this snack bar!
