Densely populated cities require large supplies of foreign goods to maintain normal operations.

In view of the similarity between the population density of the rescue city and the height of Hongkang Island, the current situation of Hongkang Island can be used as a reference object for the rescue city.

Taking Hongkang Island as an example, from water and electricity to vegetables, rice, oil, salt, sauce, vinegar and tea, Hongkang Island cannot meet its own needs, and most of them rely on foreign supplies.

Without external support, Hongkang would have lost 66 percent of its eggs, 70 percent of its fresh water supply, 92 percent of its fresh vegetables, 94 percent of its fresh pork, 100 percent of its fresh beef, and 90 percent of its overall food supply.

To put it simply, if the supply of foreign goods to Hongkang Island is cut off, Hongkang Island will lose 90% of its food source, and in the absence of food, will Hongkang Island be able to maintain such a high population density?

The answer, of course, is no!

According to Fan Fangsi's planning of the rescue city, although the population density is similar to that of Hongkang Island, it is two orders of magnitude worse in terms of total population!

The total population of Hongkang Island is only about 13 million, but the rescue city is designed to accommodate a total population of 100 million.

Although the population density is highly similar, with a total population of 100 million, the amount of materials needed to rescue the city is also two orders of magnitude lower than that of Hongkang Island.

With such a total population, how much foreign supplies are needed to maintain the normal operation of the rescue city?

Fan Fangsi snapped his fingers, and the Reality Gem displayed the information that Fan Fangsi had constructed in his mind in the third living room, as if it were three-dimensional light and shadow.

"The eight rescue cities are only designed for a total population of 100 million, not really accommodating 100 million people." Fan Fangsi nodded in the void, "According to my design plan, the eight rescue cities will be matched with the same number of resource cities. ”

"Taking Shicheng and Rongcheng as examples, I plan to set up Shicheng and Rongcheng as rescue cities, relying on the current urban construction, and in the next three years, we will renovate Shicheng and Rongcheng on a large scale, so as to build a dense rescue city with a total capacity of 100 million people." Fan Fangsi narrated.

"In the north of Shicheng and the south of Rongcheng, we will continue to plan two resource cities, the two resource cities will mainly provide all living materials for Shicheng and Rongcheng, and we will try our best to plan the most basic living materials in the two resource cities, just like the super earthworm project in the Wandering Earth plan, we only need to ensure the minimum level of production of living materials." Fan Fangsi continued.

"Eight rescue cities and eight resource cities will be paired to form an urban agglomeration, and the resource cities can also increase the population capacity by an additional 10 million." Fan Fangsi added the narrative.

Zhang Enmin did a quick calculation, he had been planning how to rescue more people, and it only took him a few minutes to identify the relevant problems with the plan proposed by Fan Fangsi.

"If you ignore all the problems, the plan proposed by Mr. Fan is indeed feasible!" Zhang Enmin's rational judgment.

The plan proposed by Fan Fangsi is feasible, but there are too many problems, if it weren't for the plan proposed by Fan Fangsi, Zhang Enmin would have scolded him, okay?

Building rescue cities and resource cities on the ground?

How to deal with extreme cold weather?

When the Wandering Earth project is implemented, the temperature on the earth's surface will drop to minus 80 degrees Celsius, and such a temperature will freeze all life on the ground.

"Tell me what the problems are, and we'll solve them one by one." Fan Fangsi asked.

Zhang Enmin immediately raised the issue of extremely cold weather.

Regarding the problem of extreme cold weather, Fan Fangsi actually has a solution!

In the Star Wars world, Fan Fonth has been preparing plans to build larger warships, whether it is the two Nemodians of the Trade Alliance, or the Skynet that Fan Fonsi has previously pitted, they have designed more powerful deflection shield generators.

According to the properties of the deflection shield to block energy, it can completely isolate the transfer of cold and hot energy.

Fan Fangsi only needs to return to the Star Wars world and design and manufacture a semi-circular spherical deflection shield with a diameter of 100 kilometers to isolate from extreme cold weather.

As for the protection of underground space?

The big deal was to dig a circular downward trench around the edge of the city, so that the deflector shield could be integrated into the ground, and it would only take 500 meters or a little deeper to insulate the extreme cold from the outside.

After all, there is geothermal heat in the depths of the earth, and it is impossible for the ground to transmit too much cold down hundreds of meters underground.

"I can solve the problem of extreme cold weather." Fan Fangsi explained in detail, but he didn't say anything about the bias shield, but said that there was an immortal magic array that could solve the problem.

At most, it's just to use the reality gem to change the shape of the deflection shield generator, so as to change the deflection shield generator into the core of the immortal magic circle full of fairy flavor?

Zhang Enmin listened attentively, "If the problem of extreme cold temperature is solved, the biggest problem will be solved." The second major problem is energy, whether it is a rescue city or a resource city, even to maintain a minimum subsistence guarantee, it needs to consume a lot of energy. By the way, Mr. Fan, what we need is electricity. ”

Fan Fangsi thought about it for a while before responding, "This question is still not a problem. ”

In the Marvel world, the tokamak device on the ground floor of the Stark Industries building can supply the energy consumption of the whole of New York.

Although the population of New York cannot reach 100 million, it is really uncertain whether the energy consumed by 100 million people under the minimum subsistence guarantee is one-tenth of that consumed by New York.

What if you consume a little more?

The tokamak unit on the ground floor of the Stark Industrial Building is a small one, no more than ten meters in diameter, and a larger tokamak could have provided more energy.

"Regarding the problem of energy, I can also use the Immortal Magic Circle to solve it, and convert the energy into electricity, so that it is convenient for you to use." Fan Fangsi added.

"Meet the needs of 100 million people?" Zhang Enmin asked cautiously.

Fan Fangsi nodded slightly, "Although there will be some costs, such a price is within my bearing." So this is a problem I can solve. ”

Speaking of this, Fan Fangsi looked at Zhang Enmin and said, "We are all ants-like existences, I hope that you will finally break the shackles of fate, so as to provide me with a glimmer of possibility to break free from fate." ”

Zhang Enmin took a deep breath, and he responded solemnly, "We have fought against fate, and we have started a tragic plan to wander the earth, so as to break the fate of genocide. ”

"Now, we will fight against fate again, we will save our compatriots, we will finally break the shackles of fate, so as to win a glimmer of life!" Zhang Enmin said categorically.
