Chapter 767 (1/2)

However, after thinking for a long time, Jiang Chen did not understand what this ”just in case” meant.

Whether it was to leave a fire for the third empire or something else

and this fort is just a design drawing. It is not known whether the Fuehrer sent someone to Antarctica and built the doomsday fortress according to the orders of the void adherents. And in terms of the location on this map, the fort seems to have been lost in the blizzard all year round. Whether such a place can survive or not is also an unsolved mystery.

Do you want to go to the South Pole?

the idea suddenly appeared in Jiang Chen's mind, and it expanded uncontrollably.

The shelter can not control the direction of the war, but provide a grave for the loser. No matter how you think about it, it doesn't make sense. However, the adherents in the void will not insert a useless piece of information into this piece of information without any reason. The reason why they did this must have their reason

but what would it be

the next day, Jiang Chen, who had enjoyed himself in Penglai City, returned to Koro island with Aisha and Xia Shiyu.

Because of her work, Natasha flew back to Moscow the day before the charity party. So on the return flight, there were only three of them, Jiang Chen.

Back on the island, Xia Shiyu's first thing is to go home to put his luggage, and the second thing is to go to the future people building. Without stepping into the office for a week, the accumulated work must be as high as the hill. Although her assistant can help her to deal with some of the documents, she has to make decisions on many issues related to the operation direction of the group.

Jiang Chen returned to the villa with Aisha. After a short rest, he began to be busy.

On the one hand, he is preparing for a trip to Antarctica. On the other hand, he is also planning to build an undersea highway tunnel to connect Panu island into a whole. In this way, people don't 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, you should build roads first. This is the truth that will never change. If there is such an undersea tunnel, which can connect the nine islands of the Panu islands as a whole, it will have a huge driving effect on the economy of the whole new country.

Besides, once the tunnel is completed, the demand for cars in the new country will certainly have to rise by one level.

Nevertheless, the construction of this day's tunnel is not an easy task.

There are many ways to build subsea tunnels, and there are four representative methods, such as drilling and blasting method in Qingdao, Xiamen and other places, immersed tube method in Xiangjiang River, tunnel boring machine method in English Channel and shield method in Japan.

However, all four methods have one thing in common.

Taking China as an example, the construction cost of the 123 km high-speed railway subsea tunnel from Dalian to Yantai under construction is as high as 260 billion yuan, and the average cost per kilometer is more than 2 billion yuan. Even if the cost of 129 million yuan per kilometer of high-speed railway is removed, it is still a terrible figure to build such a pipeline

and this budget is only a conservative estimate If we want to connect all the nine Panu islands, it will be more than 123 kilometers. The straight-line distance between ANGA island and Koro island at the southernmost point is more than 150 km, equivalent to the distance from Wanghai to Hangzhou.

It is conservatively estimated that the undersea part of the highway will have to be at least 300 km long if the tunnel is to be built to connect all Panu islands. If the project is contracted out to Chinese builders, the whole project will cost at least 60 billion US dollars.

Sixty billion dollars, boy. This money is enough to build two more Penglai cities. Even if futuren group has money, it can't follow this pattern.

Fortunately, the future human heavy industry has made a breakthrough in graphene technology. In the two fields of semiconducting graphene and high-strength nano materials, it can be said that no scientific research institution in the world is the rival of the Materials Science Laboratory of futuren group.
