The ambiguity of the Imperial Ministry of Communications made Zhuang Bifan feel the urgency of time. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info He put Sima Yun on the plane, and he swaggered on the aircraft that came to receive the record again at noon, and went to Aurora Island in full view of everyone.

When Sima Yun arrived at Longzhou Airport, he was taken to his East Palace by Ming Ziluo.

For this woman who caused the Ma family and the Sima family to be in trouble, it was the first time for Ming Ziluo to see her face to face. After meeting the real person, he understood why Zhuang Bifan would clash head-on with the two families for her. He also saw in the eyes of this petite woman a fortitude that many men could not match.

Neither side intended to publicize the meeting, but neither deliberately kept it secret. The two of them met in the spacious study of Mingziluo's East Palace, along with Mingziluo's secretary.

Sima Yun didn't propose to let his secretary recuse himself, since the other party could stay present, it must be someone that Ming Ziluo absolutely trusted.

After a polite exchange between the two sides for a while, Ming Ziluo opened the window and said brightly: "Miss Sima, I received a call from Mr. Zhuang, and he said that you would meet me on his behalf. I guess you're here because of something I negotiated with him before. ”

"Your Highness is right!" Sima Yun said with a confident smile on his face. Bi Fan hopes to complete the exchange of that land as soon as possible. The exchange on our side is ready. As long as you follow your agreement, things can be delivered to the place designated by His Highness within a week. ”

Ming Ziluo pondered for a moment and said, "For the exchange of that land, my side has obtained the power to be fully responsible. It can be exchanged at any time. But isn't Mr. Zhuang worried about the negative impact on his other plans?"

"Some things are always risky. Sima Yun smiled and said confidently. And Bifan wasn't very worried. Besides, we can temporarily block the news after signing the agreement. ”

"Since Miss Sima said so, I can cooperate with your plan. I don't know when Mr. Zhuang will be available to sign the agreement. I just got the news that he's gone to Aurora Island again. ”

"In two weeks, he'll be back. "That kind of agreement still has to be signed by Zhuang Bifan himself. Sima Yun gave a relatively generous amount of time. "Actually, Bi Fan entrusted me here, and there is another plan that I hope to get the support of His Highness. ”

Ming Ziluo raised his eyebrows and said with a smile: "Mr. Zhuang's plan is definitely a big project. Miss Sima, tell me about it?"

"Your Highness, a hundred years ago, our country's Grand Canal was a major transportation artery in the eastern part of the empire. However, with the frequent interruption of the lower reaches of the Yellow River, only the southern and northern sections of the waterway are navigable. Other sections of the river, even during the flood season, are no longer able to cope with each other due to heavy siltation. In addition, the lower reaches of the Yellow River have become a de facto seasonal river, and in the worst year, the estuary has been flooded for less than a month. And the downstream has become an above-ground river. In the past century, there have been 19 breaches in the lower reaches of the Yellow River, and the losses have been very large. ”

Ming Ziluo interrupted and said, "I know what Miss Sima said. Moreover, Mr. Zhuang also mentioned to me before about the dredging of the Grand Canal and the Yellow River. If it can be done, it will be good for the whole country. But I wonder what you guys do. ”

"Bifan can turn the Yellow River into a normal river without affecting the flood control capacity of the existing embankments. The riverbed is reverted to flat land below the sides of the riverbank. Sima Yun smiled slightly and said. "Of course, the Grand Canal will also be dredged, so that the entire waterway has a depth of more than eight meters. ”

Hearing her say this, Ming Ziluo couldn't help but be moved. Not to mention the Yellow River, the dredging of the Grand Canal is a super project. The world's Grand Canal has been widened many times, and many of the waterways are more than 100 meters wide. The narrowest point is also more than eighty meters. To dig a few meters deep into such a channel is not just a big project.

Not to mention the thousands of kilometers of rivers in the lower reaches of the Yellow River, many places are more than a thousand meters wide, to turn this river into a normal river, normally, it is impossible to complete it without hundreds of billions and decades, but she said that Zhuang Bifan has such ability. Even with the technical support of the Three-Eyed People, he couldn't imagine how Zhuang Bifan could do it.

However, Sima Yun didn't finish speaking: "Just dredging the river, if there is no water volume, of course, it will be in vain." Bifan can also allow the lower reaches of the Yellow River to be navigated by ships of 5,000 tons throughout the year. ”

After hearing what she said, Ming Ziluo immediately asked, "Is this true? The water volume of the Yellow River is not stable. How are you going to ensure that the Yellow River is navigable?"

As an important major river in the east, the navigable capacity of the Yellow River is still secondary. The most important thing is that the river is the lifeblood of the northern plains. The Eastern Northern Plain was an important economic region of the Chinese Empire, but more than 30 years ago, water became a bottleneck for the region's economic development. If the Yellow River can supply enough water, industry and agriculture in this region will benefit greatly.

For the Ming family, the country is stable, and their Ming family can always sit in this position. So they and other families think more, and they have to think more about making money than just their own families.

Sima Yun had a confident smile on his face and said, "We had no choice. Behind Dan Bifan is Aurora Island. Isn't it?"

Ming Ziluo thought for a moment and asked, "What about your conditions?"

"The right to operate the traffic of these waterways. ”

"That can't be. All the waterways of the Empire belonged to the state, and anyone's ships could sail freely in accordance with the laws of the Empire. We can't leave them to private management. ”

Sima Yun smiled and said, "That's a natural river. But these rivers are dredged and are actually canals. Now in the world, that canal is not run by a business?"

At the same time, Zhuang Bifan was still thinking about how to bring the technology and equipment to be exchanged with Ming Ziluo to the earth.

Those satellites are easy to do, and they can be replaced to Aurora Island a few more times. But there are some very large devices. It needs to be disassembled and divided into multiple times before it can be delivered to Earth. And there is no way to transport surface cargo ships over there.

He was considering whether to use a spaceship. But he was worried that it would be too ostentatious.

There are also disconnects between those technologies and the existing technology system of the earth, and the scientists of the earth want to understand it, and they don't know how much time it will take. If you want them to really master these techniques, I'm afraid they need the guidance of android researchers on the side of the Black Flame Space.

In addition to those, he is also considering whether to promote the exercise regimen and equipment analyzed by Black Flame on humans on the planet.

Now that he has seen two advanced civilizations, he feels that if human beings can live longer, the scientific and technological level of civilization should be able to improve faster. It takes thirty or forty years to train a good scientist, and the golden age of this scientist may be less than forty years, which is too short. If we can extend the theoretical lifespan, the golden time of human scientists' research can be longer. The rate of increase in the level of human technology should be much higher.

Now, while the threat of an alien invasion may be imminent, he is not as unconfident as he was before. As long as Hei Yan's side can thoroughly understand the technology provided by the Kinip people in time and build a space fleet of eighth-level civilizations, the earth has a good chance to be safe.

But he also has to consider a problem, the human population is already very large, if the life span of human beings is extended, the population growth rate will be faster, if the earth can no longer carry the migration to space, either war will break out or the earth will be out of control. What should he do if that happens? Will he continue to help the earthlings or will he be out of sight?

That's also a difficult choice.

However, he is not a person who drills the horns of the bull, and he will let go of things that he can't decide for the time being. However, he still has to bring back the equipment that can enhance the quality of the human body. He at least wants to benefit his family and Zhu Tao.

As for the others, he still thinks again. However, he can take the technology with him first, and if he finds a solution to that contradiction, he can also get a company on Earth to produce it. The core thing of that thing is actually just a chip. Other parts of the earth technology can still be produced.

Just as he wanted to return to Earth, he let Hei Yan stay for the time being.

It turned out that Black Flame had once again revised the design of the new mothership. Previously, he had asked for a bigger mothership. The design scheme given by Heiyan, the new Heiyan is a super warship with a length of more than 13,600 kilometers.

In that design scheme, in order to enhance the maneuver, according to the first fifth scheme, two auxiliary hulls connected to the main hull were added to the left and right of the tail section, and the main function of the two auxiliary hulls was to increase the launch area of the propulsion energy field. At the same time, the acceleration of left and right steering is increased.

And this time the design scheme it gave did not change much in the shape of the hull. The main ones are the addition of some in-house factories, such as shipyards capable of manufacturing warships up to a length of one hundred and fifty kilometers, and more berths for ships. The other is weaponry.

Hei Yan told him: "Although the technology of those Kinip people is still completely thorough, we have roughly figured out what is written, and in addition, our preliminary judgment is that the use of semi-metallic element alloys can ensure the combat effectiveness of this mothership in all aspects." ”

Zhuang Bifan looked at the image and felt that it was not very big. After all, it's just a virtual model that has been scaled down countless times. It was impossible to give him too much shock. But the data shows a length of more than 13,000 kilometers, and the earth can't even fit it. The amount of resources expended can be imagined. Although Blackflame expanded this mothership was designed to enhance its logistical capabilities. But he couldn't help asking: "Is it a bit of a waste to increase the number of warships that can build a length of one hundred and fifty kilometers?" ”

"As the Marshal feared, after we leave this space, we are likely to appear in the Void or in a star field where we have not been able to find a foothold for a long time. Even if we can maintain docking with this space, logistics and ship maintenance will need to rely on the mothership. ”

"If there is a battle along the way, the mothership will also need some capital ships to assist in the battle. According to our optimistic calculations, as long as the new energy storage system is successfully developed, we can allow smaller warships to complete their own space replacement on their own. This limit may not exceed two hundred cubic kilometers. Therefore, it is necessary to build larger and more shipyards. Also, according to my estimates, there is no more than a 20% chance that we will be able to get in touch with the space after we leave. Therefore, these motherships need to install artificial space and carry a large number of supplies and parts. ”

It said and gave another holographic projection.
