However, after thinking for a long time, Jiang Chen couldn't understand what this "just in case" meant.
Is it for leaving flames for the Third Reich or something else?
And this fortress is just a blueprint. It is not yet known whether the head of state sent people to Antarctica and built the doomsday fortress as commanded by the Void Residents. And from the position on this picture, this fortress seems to have been obliterated in a snowstorm all year round. Whether it can survive in such a place is also an unsolved mystery.
Are you going to see it in Antarctica?
This idea suddenly appeared in Jiang Chen's mind, and he swelled uncontrollably.
The refuge can't control the direction of the war, and at most provide a grave for the losers to survive. No matter what you think, it doesn't make sense. However, the survivors in the void will not insert a useless message into this message for no reason. The reason why they did this must have their reason ...
What could it be?
......
The next day, Jiang Chen, who had already had fun in Penglai, took Aisha and Xia Shiyu back to Coro Island together.
Due to work reasons, Natasha boarded a plane the day before the charity party and returned to Moscow. So on this return flight, only Jiang Chen and the three of them.
After returning to the island, Xia Shiyu's first thing was to go home and put his luggage, and the second thing was to go to the Future Man Building. I didn't step into the office door for a week, and the accumulated work must have been as high as the hill. Although her assistant can help her deal with some of the documents, many of the problems related to the direction of the group's business must be determined by her backbone.
Jiang Chen returned to the villa with Aisha. After a short break, he also became busy.
On the one hand, he is preparing for his trip to Antarctica. On the other hand, he is currently planning to build a subsea highway tunnel to connect Panu Nine Island as a whole. In this way, people do not need to travel by car and boat at the same time, they can drive directly to any corner of the new country.
If you want to be rich, build the road first, this is the truth that will never change. If there is such a submarine tunnel that can connect the nine islands of the Panu Archipelago into a whole, it will have a huge boost to the economy of the entire new country.
Not to mention, once this tunnel is completed, the demand for cars in the new country will definitely have to rise by one level.
But that being said, building a tunnel this day is not an easy task.
There are many methods for constructing subsea tunnels. There are four main representative methods, such as the drilling and blasting method in Qingdao and Xiamen, the sinking pipe method in Xiangjiang, the tunneling machine method in the English Channel, and the shield method in Japan. .
However, all four methods have something in common.
That is expensive! Not so expensive!
Taking Huaguo as an example, the Dalian-Yantai High-speed Rail Undersea Tunnel under construction is 123 kilometers long, with a construction cost of up to 260 billion yuan and an average cost of over 2 billion yuan per kilometer! Even if the cost of high-speed rail is 129 million per kilometer, just building such a pipeline is still a terrible number!
And this budget is just a conservative estimate!
If you want to connect all the islands of Panu Nine, it is more than 123 kilometers. The straight-line distance between the southernmost island of Anga and Koror Island exceeds 150 kilometers, which is equivalent to the distance between Wanghai and Hangzhou.
It is conservatively estimated that if the submarine tunnel connecting all the islands of Panu Kyu is to be built, the undersea part of the highway must be at least 300 kilometers. If the project is contracted to a builder in China, the entire project will cost US $ 60 billion.
60 billion dollars, good guys, this money is enough to build two more Penglai cities! Even if the futuristic group has money, it obviously cannot follow this trick.
Fortunately, Renhe Heavy Industry has made breakthroughs in graphene technology. In the two fields of semiconductor graphene and high-strength nanomaterials, it can be said that there is no scientific research institution in the entire world as the laboratory of materials science of Futuristic Group Opponent.
Among them, the graphene sheet used in the future man's building is a breakthrough to reduce the construction cost of subsea tunnels. If a tougher material than steel can be used as the outer wall of the subsea tunnel, the progress of the entire project will undoubtedly be much easier.
In early April, Future People Heavy Industries selected a partner from hundreds of construction companies in the world through a public bidding-Victoria Construction Company registered in Xiangjiang. This construction company has designed and constructed two submarine highways for Xiangjiang, and has a deep knowledge in immersed tube construction technology.
Considering that the immersed tube method is more suitable for the performance of graphene materials, Jiang Chen finally chose this company as a partner.
After the successful bidding, Victoria Construction Company immediately sent Wu Weiye, an engineer of the undersea tunnel, to the new country to meet with the future heavy industry to discuss the construction of the undersea tunnel using graphene materials.
After getting off the plane on Corro Island, Jiang Chen immediately invited him to the high-tech industrial park on Anga Island.
At the center of the wide factory building, there is a semi-cylindrical arch about 12 meters wide and about 5 meters high. The four walls of the archway are transparent, but the gloss of the glass is not visible on the surface.
With Wu Weiye walking to the transparent archway, Jiang Chen took the hammer from the staff and swung it **** it.
Boom-
Only a muffled sound was heard, and the sound continued to reverberate in the enclosed archway. Wu Weiye followed Jiang Chenluo's seat and widened her eyes in shock.
"This is our sample." Jiang Chen smiled and threw the hammer in the staff's hand, clapped his hands and looked at Wu Weiye, "The outer wall of the tunnel made of graphene material is ten times stronger than molybdenum nickel steel. , The longitudinal ductility is stronger than all metal materials, except for the problem of high temperature resistance ... Of course, there should not be so many opportunities to catch fire in the sea. "
"A car accident may occur in the tunnel, and the car accident may cause a fire, even on the bottom of the sea." While touching the outer wall of the graphene archway, Wu Weiye murmured and asked himself, "But we can The inner wall is coated with flame retardant, this is a good solution ... "
After a pause, Wu Weiye withdrew his hand, looked back at Jiang Chen, and asked seriously.
"How much does this graphene material cost?"
"This archway is about seven hundred dollars a meter."
One meter and seven hundred dollars, one kilometer is seven hundred thousand dollars, this cost is simply cheaper than steel and I do n’t know where it is going! If such a large amount of money can be saved on materials, the construction cost of the entire project will undoubtedly be reduced several times!
Thinking of this, Wu Weiye's gaze suddenly turned to Jiang Chen.
This kind of graphene pipeline, Victoria Construction Company must find a way to get it! If such high-strength, low-cost building materials can be obtained, Victoria will undoubtedly gain extremely strong market competitiveness in the global undersea tunnel construction market.
Not to mention the quality of the project, cost alone is enough to kill countless competitors.
Victoria Construction Company must establish a long-term strategic partnership with Future Heavy Industry!
Wu Weiye has made up her mind secretly. When today ’s trip is over, he will call the boss when he returns to the hotel where he stays. Make sure to clearly explain the interests. If this business is completed, this is a great achievement. Promotion is not a dream!
Jiang Chen's fiery eyes suddenly shivered and pulled away from this guy involuntarily.
Hold the grass, this guy would n’t be good ...

(I got a cold as soon as I went home. I took my temperature yesterday, 38.1 degrees, and took a nap after taking the medicine. My head was dizzy. There were two chapters in the code, and I could n’t get through it ... promise The outbreak can only be delayed by one day, I am really sorry, I tried my best TT) (Unfinished to be continued.)
