Lu Yuan suddenly heard a snoring sound and found that the little mirage was taking a nap in the shade of the tree, staring at them with a pair of confused eyes.

Over the years, it has become stronger. Its body has a diameter of 1 meter and a length of more than 10 meters. It has strong muscles, like a golden train, and weighs several tons.

As the guardian (mascot) of civilization, it has also accompanied the growth of hundreds of thousands of children.

"Ho ho!" The little mirage dragon saw the two of them running over to show their affection again, and turned around impatiently, "Can you please not disturb the dragon's sleep... He was doing experiments all night last night, and his blood was drawn.

Get out of here, both of you!

Lu Yuan looked at it for a while: "I just wanted to take my sister to fly, and a mount came."

"Roar!" The little mirage dragon became angry and sprayed ice from its mouth.

Lu Yuan's whole body immediately burst into red light, blocking the layer of ice.

"I really need to find you a female dragon..."

"Roar!" The adolescent dragon was very restless, but also slightly agitated, and his attitude became gentler.

"If it doesn't work, just clone one..."

Long was immediately furious. Are you asking me to mate with myself? Don't think I don't understand "cloning". I went to compulsory education.

Lu Yuan and Conch couldn't help laughing.

"I almost forgot that you are a tyrant!" Lu Yuan quickly took out something purple and sticky to comfort it, and then eagerly wanted to ride on it.

In the end, this guy couldn't resist the temptation of the purple thing. He shook his body hypocritically and tried to push Lu Yuan away.

But as he ate, he couldn't stop, his whole body was shaking and he was devouring it.

Lu Yuan quickly called to the girl and rode on her fiercely.

"roar!"

"I'm trying to pick up girls! You can't lose my face in front of girls." Lu Yuan patted the little mirage with a mouth full of purple and a happy face.

"Dajin" originally wanted to take a nap after eating, but for the sake of food, he had no choice but to endure it and obediently started to fly in the clouds.

Looking down from the highest point, you can have an unobstructed view of the entire city.

Exactly 52 years have passed, and the green city has changed dramatically!

The current Sky City, after long-term expansion, still has three floors: upper, middle and lower.

But the area at the bottom has expanded to 200 square kilometers. It is where the agricultural area, military area, experimental area, green mountains, coral islands, quantum civilization flying saucers and high-risk laboratories are located. In case something goes wrong, the bottom level is actually

You can give up directly.

The middle layer is 150 square kilometers, which is a residential area and an industrial area. There are huge elevators that connect the upper, middle and lower floors, allowing people to travel easily.

The uppermost 100 square kilometers is in the shape of a trapezoid, with a total area of ​​450 square kilometers!

That is to say, the green school area occupies 8.89%. This ratio is actually so-so and considered healthy.

The top floor is the lighting area, where you can enjoy sunlight all day long. It has the best environment and the highest safety. Various rare plants, most of the green school, and some parks and squares are placed here.

A large number of rail trains come and go, and the current total track length is as high as 2,600 kilometers, which is actually quite a lot in such a small city.

A bright silver solar panel covers most of the eaves area.

Well, it’s not the traditional materialistic route, but some glyphs that specialize in collecting heat energy - there’s no way, there are so many glyph practitioners in humans now.

In addition, the emergence of ideal energy storage technology is equivalent to using glyphs to reproduce the lithium batteries of the past, providing sufficient energy for various public equipment in Green City.

The green rattan acts as an elevator, allowing pedestrians to come and go.

The mix creates an ordinary scene in Green City, which is indeed a bit closer to the former Green City civilization.

The only difference is that there are also flying Zerg navigation tools that serve as taxis in the city.

These bugs are called "flying snakes". They have a carrying capacity of 100 kilograms and a flying speed of 200 kilometers per hour. They are excellent means of transportation. With just 1 contribution point, you can hire a flying snake for a whole day.

The Zerg Legion's life is very comfortable just by selling their labor force.

"How much money does our family have?" Lu Yuan suddenly asked.

"Zerg Legion?" Because there was a small mirage dragon present, Conch used telepathy. "Most of the consumables produced by the Zerg are used to support humans or are eaten by themselves. However, there is some surplus every year. After so many years, there are probably

Let’s accumulate two thousand auras.”

"Oh, that's not bad!" Lu Yuan was very satisfied. The Zerg were the bodyguards of Conch. Now that they are growing steadily, they are still doing well.

After 52 years, Leviathan is already a serious ninth-level being!

When I saw the little mirage flying by, I raised my paws and yelled "Bilibili".

The mammoth has reached level eight and is slightly smaller.

The three king insects are level 10 beings and are 2.5 meters tall.

But it may be because they are relatively young, and they have not yet been born in their own field. Yes, they are almost two hundred years old, and they are still young for king insects. For this advanced insect race, it is impossible to survive until the next era.

All are no problem.

From this perspective, the racial value of the Zerg is indeed higher than that of humans.

After all, they are part of the vision, not traditional life.

"King! Queen!"

The three king insects flapped their wings and flew over. Their speed exceeded the speed of sound, just like small bombers. The small mirage dragon couldn't fly them at all.

"It's nothing, you can go and play by yourselves." Lu Yuan waved to them.

At this moment, the contact device in his pocket suddenly rang. Lu Yuan did not dare to neglect and quickly connected it. There was a call from the secretary's office, "Commander Lu, people from the Underground Alliance have arrived."

"Okay, I'll be there right away." Lu Yuan patted the little mirage underneath.

Its speed was very fast, and it floated to the "counter-communication area" in a short time.

Many government officials are receiving the allies of the Underground Alliance. This time, more than 5,000 people came to the gathering, including scientists, engineers, and soldiers.

It’s simply a grand event for communication!

There is actually a small city near Green City, covering an area of ​​about 40 square kilometers, with two floors, a total of 80 square kilometers.

This was mankind's original promise, that it would use its redundant productivity to give the Underground Alliance a small city.

Now, this small city has been completely formed, and even some of the "strong" carvings on the walls have been carved for them.

Of course, humans will not give away the furniture, water, electricity and other internal structures. It is considered a large rough house.

This large wave of guests is here to receive this small city.

This inspection took another half a day, and every corner was checked. No problems were found, and the Underground Alliance felt at ease.

"We will keep the friendship of your civilization in our hearts, and hope that our friendship can transcend time and space and last forever!" The general chairman of the Underground Alliance has been replaced by another one, and he has become the great elder of the slant-eyed clan.

The big-headed guy said excitedly: "This city fully meets the standards set at the beginning. The subsequent expansion work will be left to us..."

"When will your civilization set off?"

Lu Yuandao: "After discussion, we decided that on the 30th of next month..."

"Are you so anxious? In fact, you can stay for fifty more years, waiting for the next insect wave and another big harvest." The elder of the squinting tribe warmly invited.

That's right, just last year, there was a large-scale killing in the insect nest, and the Rift Zerg died in large numbers!

As the Zerg population dwindled, the Demon of Greed began another wave of corruption.

The income this time is actually not as good as the first wave, because the legendary and excellent mushrooms grow very slowly, and 50 years is not enough at all, but I still got nearly 10,000 auras!

Calculated this way, the Lingyun in his hand has accumulated to 23,000, which is a considerable number.

In addition, Lu Yuan also has 30,000 Lingyun in stock, which adds up to 53,000. This value is indeed quite exaggerated!

However, the number of "luck" did not increase significantly, because the last rescue of Yunhai City consumed a full 5 points of "luck". If you want to make up for it, you have to wait more than twenty years!

"Luck" is really the most precious energy.

Humanity and the Underground Alliance also gained a lot from the mushroom-picking strategy.

In other words, if you stay in this rift, there will be a bumper harvest every 50-100 years, which is really unimaginable!

But Lu Yuan firmly shook his head and rejected the other party's proposal: "It's really nice here, but it's still too comfortable..."

"This is my intuition. Don't be greedy for this resource, you still have to witness the larger world."

He looked towards the distant horizon: "Once you stop, it's very difficult to get up again. It's like running a marathon. Once you stop, you can't run again."

The squinting elder said: "Your civilization is already a third-level civilization, right? Various technologies are much better than those of our alliance, and the proportion of divine skills is also very high..."

"Level 3 civilization is far from enough." Lu Yuan sighed, "We must take a longer view. Levels like gear civilization have disappeared."

"Can we really survive the epochal disaster by guarding this money tree? How long do we have to guard it? Why not start right away."

Everyone in the Underground Alliance was suddenly speechless, and then sighed.

The total output of the rift is approximately 10,000 souls every 50 years, which is quite stable.

The 10,000 that the Greedy Demon God robbed based on his ability were actually those from the deep layers. Humans and the Underground Alliance collected only the shallow layers, and the two did not interfere with each other.

The Rift Zerg consumed more than 90% of the mushrooms themselves. Humanity and the Underground Alliance took advantage of the insect disaster to steal some leftovers. It would be absolutely fantastic to actually start a war with the Zerg!
