Jiang Yan Hai is on the way back on the freighter. They take about 18 days to complete the journey. Of course, they go directly to the place where the dock is built. However, having freighters means that they can assemble some small frigates and the like. The railway plan has already begun.
A railway will be extended directly to the riverside terminal where the freighter is currently assembled.
On the way back, Jiang Yan Hai took a look at the Yangtze River in this world captured by the satellite. I have to say... this is also a huge test for the infrastructure maniacs. The average width of the Yangtze River in this world is 1.6 kilometers. This is the average width!
The narrowest part of the river is nearly 980 meters wide, and the widest part is not the mouth of the sea, but nearly 16 kilometers wide in the middle!
According to the information continuously transmitted back by the water pattern detection device released from the upstream, its average depth is close to 12 meters, and the shallowest place is more than 7 meters deep.
The river transportation in this world is definitely extremely developed, especially since there are no bridges built in this world for the time being, the construction height of the bridge can be raised higher. The height of the first Yangtze River bridge in reality did not take into account the development of later generations at that time, which seriously restricted the navigation status of the Yangtze River.
In this world, these problems can be considered directly in advance.
But to be honest... with this water flow, if you want the entire Three Gorges Dam of the Yangtze River in this world... it's probably impossible.
That is really a bit perverted, and the construction of the Yangtze River Bridge in this world is estimated to be much more difficult than in reality.
It is estimated that the vegetation in this world is better preserved, so its water flow is so huge, but this is related to the entire continental shelf and other structures.
Even the shapes of the continents are different. There is no comparison between these. For example, there is no Himalayan Mountains in Daqin. The highest peak in the world is at least 9,000 meters above sea level, which is also near Daqin. However, in the northwest corner of Daqin, the entire mountain range stretches for more than 4,600 kilometers from south to north, stretching into the Arctic Circle.
The average width of the mountain range is about 180-460 kilometers. The number of peaks here that exceed Mount Everest is estimated by satellites to be more than 20.
This mountain range also has its name in Daqin, it is called Kunlun Divine Mountain, and the altitude of the mountains over Kunlun Divine Mountain is also about 2500-5000 meters, a bit like the Qinghai-Tibet Plateau, but in a different location.
There are also mountains where the Himalayas originally were located, but the highest altitude of the terrain there does not exceed 4,000 meters, so the abundant water vapor from the Indian Ocean directly enters the inland.
It is estimated that this is one of the reasons why the water flow of the Yangtze River and Yellow River is so huge. Anyway, these are matters for geographical and meteorological astronomers and do not need to be considered by Jiang Yan Hai.
When Jiang Yan Hai was about to approach the mainland, Bei Chen Xiang connected to Jiang Yan Hai's communication.
"We found an abnormal location." Bei Chen Xiang said.
"Where?"
"Penglai Island is located on the sea surface of Yu Dong." Bei Chen Xiang gave an address.
Jiang Yan Hai immediately took the map. Penglai Island is what people in this world call it. In fact, it should be the real Japanese Island. However, the Japanese Island in this world, together with Ryukyu, go south to join the Treasure Island, and then connect to the mainland at the Treasure Island.
Therefore, they should be accurately called peninsulas in this world.
However, the area where they connect to the mainland is only 28 kilometers wide, about 80 kilometers long, and has an average altitude of about 5 meters.
The altitude here means that during typhoon season, it will definitely be flooded by sea water.
However, when there are no strong winds and waves, it can still be connected to the mainland, and this passage is also full of plants.
"On the highest mountain of Penglai Island, we found a geographical structure that looks a bit like a crater. However, after our analysis, it doesn't look like a crater. It looks a bit like the mountain was blasted from the inside."
"And around it, our high-precision satellite images captured many man-made objects similar to altars, but no trace of human habitation has been found so far."
"Is there any trace of Red Mad Wolf?" Jiang Yan Hai asked immediately.
"Yes, but the number is not large, and we have calculated the traces of the 2,000 Red Mad Wolf that went to North America before. They may have come from near the area connecting Penglai Peninsula and the mainland." Bei Chen Xiang said.
"Where are those Red Mad Wolfs we installed trackers on before?" Jiang Yan Hai asked again.
"According to our tracking, they seem to be migrating." Bei Chen Xiang gave an answer.
"Migrate?" Jiang Yan Hai was stunned for a moment.
"Yes, they are migrating to the west. They have joined a large number of Red Mad Wolf groups and are gradually migrating to the west." Bei Chen Xiang said.
Jiang Yan Hai narrowed his eyes slightly, this is a bit interesting. Is this an instinct to seek advantages and avoid disadvantages?
"Is there no Red Mad Wolf group in our territory anymore?" Jiang Yan Hai asked again.
"No." Bei Chen Xiang answered simply.
"Tell Lu Shi that I need him to speed up the progress and negotiate with other warlords. He must complete the reunification this summer, and we can give him absolute support." Jiang Yan Hai said in a deep voice.
"Brigadier, the deputy brigade commander wants to talk to you." Bei Chen Xiang replied.
"Okay." Jiang Yan Hai nodded.
"Brigadier, it's me." Master Kang's voice came over.
"Well, did you hear what I said before?" Jiang Yan Hai asked immediately.
"I heard, there should be no problem with this. I have talked with the political commissar responsible for training them before. The thoughts of those soldiers before Lu Shi, anyway, just don't compare them with those warlords during the Republic of China. They are not comparable."
"The soldiers in this world understand very well why they are fighting, and their mental state is very good." Master Kang said immediately.
Jiang Yan Hai nodded immediately, which was not surprising to him, because this world has always been on the edge of life and death! Da Qin and Red Mad Wolf have been working together for hundreds of years, can you believe it?
Of course, these soldiers understand what kind of situation a good life comes from. It is completely different from their own history. This is not a foreign enemy, this is a pure genocidal war, so these soldiers feel it even more deeply.
When a nation has experienced too much suffering for too long, a style has been formed in their bones. Historically, the Han people are not a tough nation. We are more of a nation that can be like a humble gentleman, or can become a strong and soft nation.
However, any nation will change. Any nation can continue to fight for hundreds of years without falling. Even if it is a war between man and beast, it will become extremely iron-blooded.
This is the case with people in this world. Even an eight or nine-year-old child, a woman, or an elderly person has the courage to fight against the enemy.
