Chapter 60 200-ton fast transport ship under construction

After entering the Le'an River, Wang Jiankun adjusted the searchlight and directed the light 100 to 200 meters ahead. At the same time, his superpowers were also projecting the underwater river terrain 90 meters ahead.

At the beginning, they sailed downstream at a speed of 5 knots for more than 10 kilometers. This section of the river was relatively shallow, with a depth of only 3 to 4 meters in the middle of the river. Wang Jiankun was not very familiar with driving a boat and did not dare to drive too fast.

After passing Xingangshan Town, the river became deeper, with the center of the river generally about 5 meters deep. So we slowly increased our speed and reached 10 knots.

Then we drove at a speed of 10 knots for more than 2 hours, passed Haikou Town, and arrived at Sizhou Town.

Dexing Copper Mine is more than 20 kilometers south of Sizhou Town, and the navigation test is half completed here.

Then we turned around and headed back from Sizhou Town. Since we had already created a topographic map in our mind and had an understanding of the depth of the entire river, we could test the maximum speed of the boat.

Gradually increasing the horsepower, the speed began to rise from 10 knots. When it reached 20 knots, Wang Jiankun felt it was already very fast, although converted into kilometers it was only 37 kilometers per hour, which was incomparable to the more than 80 kilometers per hour he had ridden on a motorcycle before.

On the wide river, a gray boat quickly crossed the calm river surface. After running steadily for a few kilometers, it checked the gasoline engine, gear system, propeller, etc. and found no problems.

At the same time, the track of the ship sailing across the water was also projected into his mind, allowing Zhizi to conduct modeling and analysis.

Then he increased the gear and increased the speed of Experiment No. 1 to the fastest 35 knots. During this time, Wang Jiankun had been projecting the ship's navigation conditions into his mind for Zhizi to analyze.

After the sailing speed stabilized at 35 knots, I tried to increase the gear to the maximum, and the speed actually increased a little to 36 knots, and that was against the current. If it was with the current, it might have reached 38 knots.

After passing Xingangshan Town, Wang Jiankun slowly reduced the speed to 15 knots, and when he reached the bay, he reduced it to 5 knots. He manipulated the rudder and gear and backed the boat into the temporary dock.

I looked at my watch and it took me nearly three hours to get there, but after speeding up on the way back, it only took me 3 hours.

It was already past 1 a.m. on Saturday. Wang Jiankun hurriedly checked the boat and asked Chieko to analyze and improve it. He then quickly surrounded the dock with a large piece of fake bamboo, then rode his motorcycle back to Yuyu Garden to rest.

During Saturday morning reading, Wang Jiankun forced himself to get up and go to school. Seeing that he was very sleepy, the class monitor Yu Zirun asked him to rest on the table and she would remind him when the teacher came.

Wang Jiankun, who had slept well during the morning reading, regained his energy. In the morning, he corrected the test papers of his seven disciples one by one, and then asked Zhizi to prepare learning materials and test questions for the next week based on each person's characteristics and learning ability.

After lunch at the cafeteria, I went back to the underground base to prepare study materials and test papers. I packed them separately in brown paper bags, wrote my name on them, and returned to school to give them to Fang Guihua to help distribute them.

After class at noon, Wang Jiankun ran to the market to eat first, then bought some rice, noodles, oil, salt, sauce, vinegar, etc. He also went to a cotton-fluffing place and paid extra money to buy two freshly-fluffed quilts.

Wang Jiankun took these things and rode a motorcycle back to the underground base, and brought them to Experiment No. 1 at night.

In the afternoon class, Wang Jiankun first flipped through the geography book and saw that the domestic map in the book was very simple and did not mark the locations of the waterways. So he searched for the atlas in his mind and found the atlases of various provinces in the country.

First, let’s look at the map of Jiangxi Province. According to the scale, the total length of Le’an River is about 280 kilometers, and the distance from the temporary wharf to the entrance of Poyang Lake is about 240 kilometers.

Then the most navigable waterway in Poyang Lake is 60 kilometers away from Hukou Town on the Yangtze River.

Then we connected the maps of several provinces and cities in the lower reaches of the Yangtze River and measured the information of the Yangtze River waterway and the canal waterway.

It is about 700 kilometers from Hukou Town to the Shanghai seaport, and about 600 kilometers from Hukou Town to Yangzhou.

According to the current economic speed of Experiment 1 at 30 knots, it is about 56 kilometers per hour.

It takes 4 and a half hours to reach the entrance of Poyang Lake from the temporary dock, 16 hours to cross Poyang Lake to Yangzhou, and 19 hours to reach the seaport of Shanghai, not even taking into account the situation where one person needs to rest while driving the boat.

Wang Jiankun decided to set off for Hukou Town tonight to discuss with Tomoko the addition of some equipment to facilitate navigation.

The first is navigation. The waterway of Poyang Lake is wide and there are few reference points. Moreover, the visibility is even worse when sailing at night, and the navigation marks may not be clearly visible. Therefore, we asked Zhizi to design a compass, sextant, and laser gyroscope, and integrated them into the control panel.

Then he asked Tomoko to help design sonar and a small radar.

Sonar is used to check underwater terrain. The scanned terrain will be stored in a special computer system, allowing the ship to automatically avoid shallow waters and areas with underwater sunken ships or reefs when sailing in the future.

The small radar is also used to measure and record the terrain on both sides of the Taiwan Strait, making it easier for Wang Jiankun to manufacture an autonomous driving system in the future.

During the first few voyages, Wang Jiankun could only rely on himself or the more reliable people in the team.

Because we have no sailing experience and we have to sail at night to save time, an automatic driving system is very necessary.

Because these devices and instruments have never been seen in real life, they are designed based on basic physical principles and mathematical modeling.

The reference materials are also some basic schematics, theoretical calculation formulas and data, so Wang Jiankun needs to constantly test and adjust the design after manufacturing.

During the afternoon break, Wang Jiankun told Fang Guihua that he would not be at home the next day, and asked them to go to the waste recycling station for dinner by themselves. They could play with the computers and the small laboratory by themselves. He had already told Ye Wei and his wife that he would wait for them to arrive before leaving.

As soon as the get out of class was over in the afternoon, Wang Jiankun returned to the underground base and took the daily necessities he had bought and 5 kilograms of gasoline to the temporary dock.

He hid the motorcycle and two-wheeled vehicle in the cave, loaded cans of gasoline onto the boat, put daily necessities in order, checked that the dock was hidden, and then sailed back to the bay.

After leaving the bay, the boat speed was increased to 15 knots, at which speed Wang Jiankun had time to react and remove underwater obstacles in time.

After driving for a while and arriving at Sizhou Town, Wang Jiankun began to consciously collect some elements within the range of his superpowers to make instruments.

The first thing is the simplest compass and sextant, then they are digitally transformed and the data is connected to the manufactured computer. From now on, the computer will record and save the navigation information.

The next step was to make the sonar. At the beginning, the image displayed after the sonar was connected to the computer was very unclear.

Then we made improvements one by one according to the principles, and it was not until it reached Leping City that it could be barely used.

Chieko said that the sensor was not sensitive enough, and the materials made according to the information in her mind were very ordinary, and she needed to continue experimenting with new materials.

It will take some time to research new materials in the short term, but when I have time in the future, I can set aside some time every day to study the materials.

Peter has also been entrusted to continue collecting foreign scientific journals, and my uncle also helps collect domestic journals in universities in Guangzhou.

With the world's top talents paving the way ahead, and using my superpowers to accelerate research and testing, I believe that the products I will be able to use in the future will be the most advanced.

After the sonar system was usable, Wang Jiankun felt a little more relaxed. He no longer had to keep recording the terrain in his mind. He just had to pay attention to whether there was any danger in the river ahead.

After passing Leping City, the Le'an River has reached a flat area. The river surface has also become much wider, reaching more than 160 meters, and there is a trend of gradually widening. The water depth has not increased much, and is still about 5 or 6 meters.

Then Wang Jiankun devoted some of his energy to making a small radar. According to the drawings given by Zhizi, he mobilized underwater elements to make the radar.

After manufacturing, connect the lines according to the connection method given by Zhizi, and then turn on the radar to test it.

At this time, the river was wide, and there were some small hills a few hundred meters away. On the radar screen, the outlines of several hills flashed one after another.

This is because this radar still uses mechanical scanning, and the antenna is constantly rotating, so the pattern will appear in a certain period.

After careful identification, it was found that the outline of the river was not very clear, so the results were fed back to Zhizi, asking it to further optimize the scanning accuracy and the received signal processing accuracy.

Modifications and adjustments were made all the way until it became barely usable in Poyang County.

The radar signal is then digitized and connected to a computer. According to a previously written program, several signals are combined together and combined into an electronic map and navigation data in the computer.

It was already past 1 a.m. at this time. Wang Jiankun found a bay that was off the course and surrounded by barren mountains and parked the boat there.

He returned to the pilot's living cabin below the cockpit, spread out the blanket and went to sleep. On Sunday morning, Wang Jiankun was awakened by the sound of birds.

I woke up and looked around. After thinking for a while, I realized that I was on a boat. Last night, I drove the Experimental Boat No. 1 all the way to Poyang County, and now I am at the edge of Poyang County.

I looked at my watch and found that it was already past 8 o'clock. Because the river was covered with fog, the sun was only a vague outline in the sky.

I resisted the cold with perseverance, put on a sweater and a cold-proof jacket, went to the stern of the boat, fetched river water to wash my face and brush my teeth.

Seeing fish swimming around the boat, Wang Jiankun used his superpowers to make a net and scooped up several chopstick-sized fish. He then gutted them and pickled them with salt.

Then light a fire and wash the rice to prepare a pot of rice. Then heat up the oil in a pan and fry the marinated fish. When both sides are golden brown, add ginger, garlic and soy sauce. Then add the river water that has been filtered using super powers.

While the rice is being cooked, the fish can be eaten. Take out bowls, chopsticks and a colander from the small kitchen, serve the rice with the cooked fish in the iron pot and start eating.

At this time, the fog had dissipated and the sunlight shone warmly on the black winter clothes.

The fish was very delicious. Wang Jiankun ate it slowly and ended his breakfast with a bowl of fish soup.

In order to save trouble, he used his superpowers to clean up all the pots and pans, and after packing up, he started the boat and headed for Poyang Lake.

It was already daybreak. I glanced at the rotating radar antenna on top of the ship. Afraid that passing ships would notice anything unusual, I searched for some information in my mind and found a material that would not affect the transmission of radar waves to cover the radar antenna.

The outside of the radome was also painted gray, and the top structure was adjusted to make the radome less conspicuous.

After entering the main channel, I saw that the radar, sextant and compass were all working normally, and the computer was synthesizing the received data into electronic maps and navigation data. Only then did I feel relieved and observe the situation around me.

The waterway from Poyang County to Poyang Lake is becoming wider and wider, and the number of ships on the water is increasing and becoming larger and larger.

Fishing boats are generally not on the main channel. The fishing boats that Wang Jiankun saw were relatively small, more than 8 meters long. There were usually two people on the fishing boat, one rowing the boat and the other casting the net.

There are also people who operate a boat alone. When they see a school of fish or think there are fish, they lower the oars, pick up the casting net and throw it out. Generally, they can throw out a large circle, covering hundreds of square meters of water surface.

Wang Jiankun's ship was very fast compared to the tugboats and passenger ships on the waterway, but the sound of his ship was so small that one could only hear it when it got close.

Looking at Experiment No. 1 passing by quickly, many people were surprised and pointed at Wang Jiankun's boat and talked to each other.

We drove at a speed of 20 knots for nearly two hours across Poyang Lake and arrived at Hukou Town.

On the left is Meijiazhou, a sandbar formed by the impact of the river, and on the right is Hukou Town.

At this time, the water surface at the river mouth is wide, several hundred meters wide, and Hukou Town is looming in the distance.

Wang Jiankun controlled the boat towards the shore. When the water depth approached 2 meters, he no longer approached the shore, but slowly sailed along the shore. He planned to find a place to stay here.

Both banks here are mudflats formed by the sedimentation of silt brought by the water flow, so it is really difficult to find a place to dock.

It was not until we entered the Yangtze River and arrived at the side of Hukou Town close to the Yangtze River that we saw a small port where ships could dock.

At this time, there were several passenger ships docked at the pier in the port, and tugboats were at the cargo terminal further downstream. The passenger ships were getting on and off passengers, and people with families were carrying their luggage and getting off from one end to the other.

Wang Jiankun docked the boat at an empty passenger terminal. At this time, an old man wearing a work suit embroidered with the words "Port Affairs" walked towards his boat dock.

After Wang Jiankun parked the boat, he took the gangplank to the dock. After stepping down the gangplank, he took out a cigarette from his pocket and greeted the old man.

"Comrade, where is your boat from? It looks very special. How long will it stay here?"

"Hello, master, please have a cigarette. I'm from Raozhou. I'm here to test this newly built boat. I'll stay here for half a day and then leave." As he said this, he handed the cigarette to the old man.

The old man took the cigarette and put it to his ear and said to him, "Comrade, you have to pay for parking for half a day. Considering the length of the dock your boat occupies, please pay 5 yuan for dock usage."

Wang Jiankun didn't know the market situation, and he couldn't leave the old man to inquire, so he paid 5 yuan and got a receipt. The receipt was addressed to Yangkou Port Authority, and the old man wrote the time the ship was docked.

After paying the fee, I asked the old man about the situation of the port. The old man told him that the passenger terminal can accommodate ships with a maximum draft of 4 meters, and the cargo terminal can accommodate ships with a maximum draft of 6 meters.

There are also standards for mooring fees. Of course, there are different standards for public ships that moor here for a long time.

After understanding the situation, Wang Jiankun decided to rest here and see if he could find a place to build a mobile base station.

During the journey, Jiankun found that he had lost contact with his family. If he asked other people to drive the ship and do transportation in the future, it would be difficult to get in touch with them.

If a mobile base station could be built at a certain distance on the waterway, Wang Jiankun would be able to contact the captain at any time, and the people on the ship would be able to contact their families at any time.

As I walked into Hukou Town, I found that people here have many different accents, and most of them speak Mandarin. There is also a street vendor every few meters.

Seeing this situation, Wang Jiankun thought it would be a good idea to find a place to stay here.

You can park at the pier as long as you pay a fee. The town must be very inclusive and strangers won't be noticed here.

They found a restaurant and ordered some food. Since this place is close to the Yangtze River, the owner recommended that Wang Jiankun eat fish. Following the owner's recommendation, they ordered a steamed river catfish, a steamed river perch, and a braised winter melon.

While eating, I asked the boss about the local customs and whether it was easy to rent a house.

The boss was also a talkative person and gave Wang Jiankun a detailed introduction to the situation of Hukou Town.

As for renting a house, the boss pointed to a place which was the house of the family members of the Port Authority. Some people moved into the newly built buildings. The empty tile houses would be rented out, and there would be people willing to sell them, but there were few buyers.

When Wang Jiankun heard that he could actually do business here, he hurriedly asked the boss for details.

The boss told him that most of the people in Hukou Town were not locals, and many of them moved here to help build the port.

Then some people will leave after staying for a while, but they can’t take the house with them, so buying and selling houses is very common.

Before the reform and opening up, it was not legal to buy and sell houses. Transactions were done secretly and were not registered. After the reform and opening up, this area was relaxed and house transfers were allowed, but taxes had to be paid.

Wang Jiankun asked the boss to point out the direction and walked towards the place where the house might be sold.

Unexpectedly, luck came. The first family I found was willing to sell their house. This family was going to move to Shanghai. They had come here before to help build the port, and now they found an opportunity to transfer to a big city.

It was just that the self-built house was difficult to deal with at that time, and when I saw this young man named Wang Jiankun coming to buy a house, I didn't think much about it and offered him a price of 800 yuan.

Wang Jiankun looked at the house. It was not big, only about 140 square meters, but there was a large yard in front of the door, which was more than 300 square meters and was also on the title deed. There was also a small hill more than 20 meters high at the back, and the neighbors on the left and right were also a few meters away from the house.

According to the owner of the house, he was among the first group to support the construction, so he occupied a large piece of land. Several households next to him were also transferred from other places at that time. Those who came later did not have it so good, and all lived in dormitories or couple rooms.

Wang Jiankun took a look and decided to buy it. He went to transfer the property to the owner and after paying the house price and tax, the land deed and the house deed were in his hands.

The homeowner was given a week to move, and he said that except for clothes and some valuables, everything else would be left to Wang Jiankun intact.

Wang Jiankun, who got the house deed and land deed, was not afraid that the landlords would go back on their word. After all, they all had formal jobs and were about to move to big cities, so they would not be able to do anything if they refused to give the deeds.

Just ask the homeowner to lock the doors and windows when he leaves, and he will come and change them himself, then leave and walk towards the pier.
