Thanks to the Detective Hell, Yan Zhiying and Lin Khan's monthly tickets.

Although the dam is very long, there are not many people living there.

With doubts, the white swan took off again and turned to the fifth settlement.

What is the most important thing for human civilization: water, oxygen, food and electricity. Under the cover of dense air defense artillery fire, the white swan successfully landed on the apron built on the dam. Wu Chen finally understood why this place became the fifth settlement of mankind.

First, she had water and electricity. Secondly, because it was an extremely important building, the elite dam guards were stationed before the end of the world. They resisted the first wave of attacks from Feilong, and the solid dam cast by reinforced concrete blocked the attack of flames and sharp claws. Again, there were fish in the river, which perfectly solved the food problem.

When Wu Chen followed the elevator to the depths of the dam, he found that there was a lot of articles inside!

The continuous supply of electricity has made the entire dam body built into a vertical and horizontal rail transit hub. There are rows of high-speed elevators up and down, and there are rows of light rail trams coming and going.

There is no problem with the elevator, but where are these trams leading?

Soon, he found the answer: the train leads to the bottom of the river!

The fifth settlement is an underwater city built on the upper reaches of the river with a dam!

It turned out to be an underwater city!

At first glance, the brightly lit high-rise buildings are rising one after another, and the dreamy submarines line up in long queues. The transparent and closed water-blocking pipes connecting the building and the submarine are!

"Where does oxygen come from?" asked, "I missed the level of a technical home."

"Oxygen produced by electrolytic water." The immigration officer who accompanied him explained with a smile.

The most inseparable thing in the Three Gorges is water and electricity. Wu Chen nodded, and then he saw many shell-shaped underwater farms. Do you only eat fish? After asking, I learned that the giant spirochete building occupying the center of the water body is the most important source of food - an agricultural plantation. The maximum water storage depth of the Three Gorges is 175 meters. If it is converted into a floor, it is 58 floors. The fire dragon obviously cannot swim, so it is quite safe to live here!

"How many people can the city accommodate?" After seeing it, Wu Chen finally felt relieved.

"50,000 people." The official blurted out.

Wu Chen nodded: "I will try my best to fill it for you."

But the official's face suddenly changed: "Can you really do it?"

"Of course." Wu Chen raised his eyebrows.

"Then please!" The otakus said that he was just a little bitch when he bowed ninety degrees.

The greatest impact of doomsday on human beings is not only survival but also reproduction.

Underwater cities solve the problem of human survival, and the reproduction of races must constantly input fresh blood to prevent the tragedy of inbreeding. At this time, humans can only place their hopes on the great sky angels, except for envying reptiles that can reproduct parthenogenerate, they can only place their hopes on the great sky angels.

"To be honest, we haven't seen the Sky Angel Rescue Team for a long time." The official led Wu Chen into an underwater jet ski.

Wu Chen scratched his head with a smile: "I guess I'm the last fool."

"No, Your Excellency. You deserve more than ever to be respected by all human beings."

"Extremely human trafficker?" Wu Chen joked.

"I have another description." The thick tongue-rolling sound is an Australian dialect that cannot be changed. "Noah's Ark."

The motorboat used a water compartment and swam in the vast and charming underwater world. At the request of Wu Chen, the officials were taking him to the "slaughterhouse" in District 5. Compared with the bloody massacres in District 7, the slaughterhouse in District 5 is obviously much more civilized. Because these fire dragons are drowned without exception.

The work of the dragon hunter in the fifth zone can be described as heaven.

They just need to use an iron-shelled barge full of salted fish to set up a trap in the right position, and the hungry flying dragon will drown in the river one after another.

The general process is as follows: the iron shells filled with salted fish are nothing except the wire grid. However, it is the barbed wire that separates the salted fish at the bottom of the cabin. It becomes a fatal gap that the fire dragon cannot escape. Without this barbed wire, the long neck of the fire dragon swooped over the barge at a low altitude to ensure that it could eat delicious food. However, because of this barbed wire grid as thick as a thumb, everything becomes a bubble.

The fire dragon must land on the barbed wire mesh and try to tear open the grid with its claws or mouthparts to eat the food below.

The danger occurs when it lands.

The barge that has been specially treated will collapse, disintegrate, and sink like building blocks when it is impacted. The flying dragon that has lost its support has no time to react and then falls into the water.

Here is the time to test your swimming skills!

The flying dragons also proved with real performance that they are indeed landslides.

It's simple, it's that simple.

Because of the development of black technology, the slaughterhouse not only has the slaughter function, but also has the Fire Dragon Research Institute. I heard that a hidden profession that was high above the mountain came - Sky Angel. The extremely excited dark scientists seemed to have met their idol's professional star-chasers, and everything to Wu Chen was not a secret. After Wu Chen learned about the body structure of the Fire Dragon in detail, he finally asked the question in his heart: "Everyone, have you ever heard of scientific madmen who study the different variants of the Fire Dragon?"

"We are all." The white-bearded old men nodded together.

"What's the discovery?"

"There is no advantageous gene for human use. The gene sequence of the Fire Dragon is more like it is designed. It is perfect and stable. Compared with our genome, it has great 'elasticity'."

"Elasticity?" Wu Chen couldn't understand.

"Yes, it's like gummy candy. No matter how you chew it, we can't chew it. We can't separate, let alone 'graft'. And even if we forcefully fuse, lower genes will be swallowed by the Fire Dragon gene as food."

"I understand." Wu Chen thought for a while and said, "I heard that there are eggs in the female dragon's body that can be hatched?"

"Yes. Some are fertilized eggs, and some are not fertilized yet. But once they leave the mother, these eggs can no longer hatch. We have tried many methods, but none of them succeeded. We even doubted whether these fire dragons were created by someone. They specialize in playing with our..."

"All paths have been blocked, right?" Wu Chen couldn't help but think that even if you don't let humans take advantage of any loopholes, how much hatred is worth!

"Everyone, I need some handy guys. Is there any good stuff to introduce?"

"Yes!" The old men raised their hands together.

Full of dragon-type weapons and various aquatic products. The white swan took off again and rushed to Elson Air Force Base.

The white swan put the last batch of refugees in, and the general stretched out: "Your Excellency, we learned from the refugees that there are still many refugee spots in this continent, and if necessary, I can hand over this refugee picture to you."

The map is refreshed again.

Wu Chen smiled and nodded: "That couldn't be better."

The white swan took off again and rushed to the fifth settlement.

On the way, Wu Chen and Crowlia seriously discussed the possibility of the existence of underwater cities.

The Three Gorges Dam is an important fulcrum. It not only blocks the burning and destruction of the flying dragon, but also provides all necessary conditions for the subsequent underwater construction: personnel, machines, food, electricity and determination. The busy Yangtze River channel also provides the necessary conditions for the gathering of large machinery, building materials and labor. In this way, first dig deep inside the dam body. Then excavate horizontally. Before the building breaks through the riverbed, ventilation pipes and water barriers are laid. Then expand layer by layer until the entire city is built. The reinforcement of the dam during this period is definitely an indispensable link. But in the face of survival, this is not a matter.

In this way, only Three Gorges can build underwater cities.

The reason is very simple. The water in places with dams is not deep enough; there are no dams in places with deep water; there are no dams in places with water and dams; there are no dams in places with water and dams and dams but no one; there are underdeveloped shipping in places with water, dams, dams, wards and people...

From this we can conclude that no matter how natural disasters are, China will come after the end of the world.

Don't accept it and think about it 2012?

The earth is flooded. Don’t we still have the Himalayas that are striking...

After several unopened fire dragons were shot in the air, the white swan landed safely. The elevator was sent into the dam, and officials from the Immigration Bureau came to greet them.

"Captain Wu, or full cabin?"

"This time it's not full, the remaining refugees are here." Wu Chen handed over the list, "275 people."

This was also a big surprise. Moreover, many of the refugees Wu Chenyun came here were strong young and middle-aged people. Only these people had enough physical strength and perseverance to avoid the hunting of fire dragons.

"Okay, OK." The Immigration Bureau officials were very happy. Although the world was in harmony, when seeing more white people arrived, the male officials from Australia were still happy from the bottom of their hearts. As a noble hidden profession, Wu Chen did everything for free. However, the conventional rule is that human remnants who were helped must provide accessories repairs, oil supplements and supplies for daily necessities.

Wu Chen's one was a nuclear-powered aircraft. The fuel was not needed, and all the white swan accessories that had been transformed by Cybertron Technology were not even mentioned. So after discussing with him, he simply converted them into survival points and stored them in his card.

"Captain Wu, 27,500 points have been deposited into the card."

Each person has 100 points. Although humans are worth much more than that, it doesn’t matter to Wu Chen, who has a net worth of 200,000 yuan.

"By the way, there's a telegram from you."

"Telecom?" Wu Chen was shocked.

"Most of the relay stations of wireless networks have been damaged, so telegrams have become the fastest and cheapest means of message transmission." The official smiled and handed the handheld computer to Wu Chen. The interface was a recorder, which was not bad. If you really wanted to give him a telegram, Wu Chen would really complain.

"Wu Chen, I am Die Wu. Park Jin-hee learned from a South Korean refugee that there are many survivors in the Seoul subway. We are still confirming the specific information and keep in touch."

After returning the computer to the official, Wu Chen turned around and returned to the plane.

Subway shelters are not surprising. Just like South Korea, there are survivors. The same reason is that the island countries in developed economies, such as South Korea, Japan, and the United Kingdom, cannot become refuge paradises. The reason is that the urban clustering brought about by development has squeezed land resources to the greatest extent. When society retreats to the point where it is worrying about filling the stomach all day long, the gorgeous technological creations of mobile phones and tablets quickly lose high added value. Of course, the narrow strategic space of island countries is also a decisive factor that cannot last for a long time.

Even if the subway can ensure personal safety, 20 years have passed, and hungry people have eaten up everything they can.

Wu Chen doesn't want to think about it any more. (To be continued) r580
