Chapter 67: Going to Yangzhou Again
After the morning reading class on Monday morning, Wang Jiankun went to ask for leave from his homeroom teacher. No teacher could stop him from asking for leave, and told him to be careful about safety. However, if he did not do well in the monthly exam at the end of the month, he should still attend school in the future, and let the adults take care of the housework.

After asking for leave, I gave the note to my deskmate Yu Zirun.

Seeing that Wang Jiankun had asked for another four days of leave, he asked with concern: "Wang Jiankun, is there something going on at home? Why do you need such a long leave? You just asked for it last week."

"There's nothing going on at home. I'm going to Yangzhou."

"Yangzhou? Is that the Yangzhou where we go to in March when fireworks are in season as written in the textbook? It should be very beautiful there, right?"

"Maybe it was very beautiful in ancient times, but it's not beautiful at all now. When I went to Yangzhou, there were chimneys everywhere. There was no beauty to speak of."

"I see. Now, in order to develop industry, many beautiful cities have changed their appearance."

"In fact, in ancient Yangzhou, only the houses and manors built by the gentry and landlords were aesthetically pleasing. The houses of ordinary people were not as good as those of the poor people today. Ancient poems and lyrics are also about those buildings built with the blood and sweat of the people by literati and poets."

"That's right, what are you doing there?"

"Cooperate with others to sell lighters. Yangzhou is at the intersection of the Grand Canal and the Yangtze River Estuary. Water transportation is well developed. It is convenient and quick to cooperate with others to sell lighters there."

"Oh, so are you going to take leave often to go there in the future? How about studying?"

"You may have to go there frequently in the first two months. The team will send someone later. But it's okay to take a leave. I learn very quickly and have already learned a lot ahead of others. It's just right for me to take a leave and wait for you."

"You're a pretty good person, so be careful when you go out. I heard there are more and more hooligans out there."

"Okay, I'll pay attention. Remember to read the study materials carefully."

----

In the morning, Wang Jiankun was listening to the lecture in class while discussing with Zhizi the construction of a base station with a longer communication range. Based on the topographic maps scanned during the last trip to Yangzhou and the East China Sea, Wang Jiankun decided to build four base stations for long-distance information exchange along the way to Yangzhou this time.

Among them, one will be built where K200 is hidden in Poyang County, one will be built in Hukou Town, one will be built near Anqing, and one will also be built in Yangzhou.

The four base stations can communicate with each other over long distances up to 500 kilometers, and the communication distance between them and the text machine can reach 30 kilometers.

Because of the progress in the research on electronics and magnetism, and the reference of some military radio and radar hardware equipment obtained from the Perry-class destroyer, the anti-interference ability and receiving sensitivity of the communication equipment produced have been greatly improved.

Wang Jiankun also thought of a solution to the power supply problem, which is to use solar power generation.

I have learned about the photoelectric effect before, but at that time I didn’t think of using it to generate electricity. This time, in order to install a mobile base station in the wild, Zhizi reminded me that I could make photovoltaic panels and energy storage equipment to solve the electricity problem of mobile base stations in the wild.

The maximum power of these four long-distance communication base stations is 200 watts, which is the power reached when communicating between base stations. The power for normal communication with text machines is only 80 watts.

Moreover, Wang Jiankun will strictly control the number of text machines and corresponding integrated equipment, so it is completely feasible to use a combination of photovoltaic panels and energy storage systems to provide power.

Each base station is equipped with four 4-watt panels and an energy storage system that can store 500 kWh of electricity, which is enough for the base station to use 10 hours a day. As long as there is no rainy weather for 24 consecutive days, there is no need to worry about insufficient electricity.

In the afternoon class, Wang Jiankun and Tomoko designed a new transport ship together, as the original K200 was no longer usable.

Originally, a diesel engine modeled after Yuchai was designed, but after seeing the military diesel engine on the Perry-class destroyer, Wang Jiankun decided to let Tomoko refer to this military model.

First reduce the size and power, as long as it is enough to allow a 200-ton transport ship to run at a maximum of 25 knots and maintain an economic speed of 20 knots.

Tomoko has become more and more proficient in industrial design, and with the virtual physical references projected in her mind, there is no problem in design.

In order to keep the size of the engine room unchanged, only one diesel engine is designed to be used, and the auxiliary engine uses a mature model of Yuchai. In case the main engine breaks down, the auxiliary engine can provide rescue power to the ship so that the ship can continue to have power and can sail at a speed of 3 knots.

Wang Jiankun asked Chieko to redesign the hull based on the appearance of a warship. When it is manufactured, modifications can be made during the sea trial. Wang Jiankun, who has driven ships for thousands of kilometers, is already confident that he can change the appearance of the ship while it is driving. However, this change has to be done at night, otherwise it will scare many people.

The upper deck of the ship was designed based on the passenger ships sailing on the Yangtze River, so Chieko tried to optimize and reduce wind resistance as much as possible. Although such a ship is still relatively fast, its shape will not be so abrupt.

This time, Wang Jiankun did not plan to sail at a speed of 25 knots in the Yangtze River. He would sail at 15 knots during the day and decide whether to increase the speed to 25 knots at night.

After class in the afternoon, Wang Jiankun went to the market as usual to buy some meat and dry food in case of emergency. In fact, every port has a canteen where you can eat and get some information.

After purchasing food, we went to the gas station and bought 2 kilograms of diesel, which was enough for the new ship to refuel in Hukou Town.

When refueling at the port, it depends on how much your ship can fill up. The staff generally won't ask too many questions, unlike the gas stations in the county who always ask all kinds of questions and require proof documents if you buy too much.

He rode a motorcycle to the temporary dock with the purchased supplies. After lifting the supplies onto the boat, he drove Experiment No. 1 to Sizhou Town. When he arrived at the dock, Wang Jiankun paid the berthing fee and rested on the boat. He would not have much time to sleep during the day and night tomorrow as he would be very busy.

The next morning, Wang Jiankun went to the warehouse in Dexing. There were already two trucks from a local transportation company waiting for him. This was arranged by his father and Du Weiqiao yesterday.
As soon as Wang Jiankun arrived, he asked the warehouse manager to open the gate and let two trucks drive in to load the lighters onto the trucks.

After loading, Wang Jiankun asked the truck to follow his motorcycle to the Sizhou Town Wharf. Once there, everything was simple. He just asked the truck to drive directly to the wharf. Wang Jiankun got on board and started the crane to quickly lift boxes of lighters into the cargo hold of Experiment No. 1.

After paying the two drivers the freight and giving each of them two packs of cigarettes, and seeing that they left with satisfaction, Wang Jiankun asked the dock manager to untie the ropes, and then he drove the boat to the K200 parking lot in Poyang County.

After arriving at Huiwan and making sure that no ships were following them, Wang Jiankun activated his superpowers to transform K200. Because the components were similar, there was no need to mobilize elements from the riverbed to supplement it.

First, the hull and keel of the ship slowly changed shape under the influence of Wang Jiankun's superpowers, and the bottom of the ship became sharper, so the draft of the ship will reach 3 meters after it is built. However, there is no problem sailing on the Yangtze River and Poyang Lake, and most ports and waterways are passable.

After the hull was modified, we came to the engine room and slowly combined the two gasoline engines into two diesel engines, one large and one small. Then we modified the gear transmission system and finally the electrical system. Many places referred to the design of the Perry-class destroyer, which would be more user-friendly and easier to maintain.

The renovation of the superstructure was completed very quickly. After the renovation, Wang Jiankun painted the hull number C200 on the side of the ship. C stands for diesel model and 200 represents tonnage.

Experiment No. 1 was used to tow the C200 out. After leaving the cave, Wang Jiankun could see its appearance clearly. The upper structure was a bit square and the bow was not that sharp. However, Zhizi had simulated calculations and found that this kind of bow would have no problem sailing at 25 knots in the Yangtze River, but the fuel consumption would be higher.

However, Wang Jiankun was not worried about fuel consumption. He was the only one who could reach 25 knots from time to time, and the team would definitely limit the speed to 20 knots. After hoisting the lighter, diesel and food on Experiment 1 onto the C200, Wang Jiankun also climbed up the gangway and drove Experiment 1 into the cave to hide.

Add diesel to the fuel tank of the C200, start the diesel engine, and after it runs stably for a few minutes, connect the transmission system and rotate the propeller to make it move slowly.

Wang Jiankun tested it for half an hour in Huiwan, making modifications during the test. With the help of Zhizi, some design errors were corrected. For example, the diesel engine was modified to be more fuel-efficient, and the noise was also well controlled. The decibel level in the cabin was similar to that of the previous K200.

After the test was completed, Wang Jiankun drove the C200 to Poyang County, during which time he installed a mobile base station, corresponding photovoltaic panels and an energy storage system on a selected mountain near the river.

Most of the elements were taken from the mountain where they were installed. Only some elements that were difficult to collect, such as copper, gold, silver, etc., which could not be extracted on the mountain, were brought up the mountain by Wang Jiankun himself.

The installation process can be described as cutting through mountains and building bridges over rivers. With the help of super powers, the road to the top of the mountain was quickly built, the mobile base station and energy supply system were installed, and then the road and the bridge were restored to their original state.

After the installation, I returned to the ship and tested it with a text machine. The mobile base station was able to operate perfectly, and local information and messages from Wuyuan could be received and sent.

After marking the location on the paper map, Wang Jiankun drove the boat to Hukou Town.

When we arrived at Hukou Town, we first went to the gas station to fill up with diesel, and then parked at the berth we had rented for three months.

Unexpectedly, the staff member at that time was also on duty today, and asked him why the boat he was driving this time was different from the last time. Wang Jiankun had to say that it was for testing, and the boat he was driving this time was a type of ship that would be determined in the future, and would mainly run the route from Poyang County to Yangzhou.

The staff also asked him whether the boat ticket was expensive and how fast it was, saying that he wanted to take this boat to Nanjing to visit his grandchildren during his rest time in the future.

It turns out that this staff member's hometown is Nanjing, and he was sent here to support the construction of the port. After the port was built, his son found a job back in his hometown Nanjing, so now he goes back to Nanjing once a month.

The public passenger ship he had taken before was slow, the cabin environment was poor, and the service attitude was very bad.

In the past six months, I have been taking privately contracted boats. The ticket prices are low and the service attitude is good, but the speed is still as slow or even slower. Those boat owners want to fill the passengers before sailing, so the boat is often delayed.

He found that Wang Jiankun's ship was quite fast and very flexible when anchored, and it was a new ship, so the speed and service would definitely be better, but he didn't know what the price would be.

Wang Jiankun had not yet learned about the transportation market in detail, so he had to say, "Comrade, this ship of mine is the latest research product, so its speed will be twice that of the passenger ships running on the Yangtze River. During the trial operation, the ticket price will refer to that of Jianghang Company, but our speed will be very fast."

"Twice the speed, that's really fast. The same price as Jiang Hang is reasonable. When will the trial run begin?"

"It is expected to be mid-December. We have another ship in the final stages of construction, and the captain and crew are also in training, so it will take another month."

"Then I can't make it this month, so I'll take your ship next month. How do I buy the ticket?"

"Comrade, I haven't thought about these yet. I might just shout at the docks at the beginning and take in as many passengers as I can. After the flights are fixed, I might find people at several docks to sell tickets for me."

"I see. You can do this when you are just starting out. Jianghang sells tickets at dozens of docks along the Yangtze River. They can also send telegrams to confirm ticket sales and increase or decrease ticket prices at any time, as well as inform the location of the ship."

"Aren't they similar to trains? They have to support a lot of people!"

"Yes, and they also employ a lot of idle people who don't work, so their service is poor and the fare can't be reduced, and the ships are not updated much."

"Let's not talk about them. Comrade, I'll give you a 50% discount if you take our ship next month. I'll also ask you for some knowledge on passenger and freight transport."

"Thank you very much. Come talk to me when you have time. I have worked here for most of my life, so I am quite familiar with the situation on the river."

"You are too modest. I will definitely come to see you when the time comes. I have something else to do in town, so I'll go take care of it now."

"Okay, okay, go ahead and do your work. Your boat is under surveillance, so nothing will happen."

After saying goodbye to his old comrades, Wang Jiankun came to the house he had bought and found that the landlord and his family had already left. He took out the spare key and opened the door, and discovered that most of the furniture was left, including the bed and cabinets in the room. He could then buy some daily necessities and move in.

He used his super powers to inspect the house, reinforced some leaking and unstable places, and modified the electrical wiring in the house so that it could provide power to the mobile base station installed on the top of the mountain behind.

Because the top of the mountain behind is not high and the space is not large, Wang Jiankun had to make a few small photovoltaic panels for power supply during the day, and rely on electricity from the house to provide energy at night.

After locking the doors and windows again, Wang Jiankun returned to the dock and drove the boat downstream of the Yangtze River.

Near Anqing, Wang Jiankun also chose a mountain close to the river and extremely difficult to climb to install the mobile base station and energy supply system. He rested for a few hours at the Anqing dock that night.

They set off in the middle of the night and sailed at the fastest speed of 25 knots for more than five hours. After daybreak, Wang Jiankun reduced the speed to 5 knots. They entered the Grand Canal at around 20 a.m.

We could only follow the boat in front of us slowly in the canal, and finally arrived at Fanjia Town Pier at 9:.

As usual, they first lifted a bicycle down, and then found Hu Yuefei and Ge Tianwei with ease. This time, they each took 1 and 5 lighters. Wang Jiankun stored the remaining 1 near Ge Tianwei's home and asked him to help look after them.

At noon that day, we were guests at Hu Yuefei's home. This time, Boss Hu did not dare to be arrogant. He stopped drinking after drinking to a certain extent and went down to drink tea. Wang Jiankun was also reluctant to drink, as it was quite troublesome to use superpowers to deal with alcohol, and it was also quite uncomfortable for the carbon dioxide to rush out.

At around 3 p.m., Hu Yuefei recovered and took Wang Jiankun to buy the house.

Since the settlement was made in US dollars, the landlord was very satisfied, so the formalities were completed quickly. The landlord also left most of his belongings behind and gave him the keys to go to Shanghai that day.

That afternoon, he went to the market to buy bedding and some daily necessities, and that night Wang Jiankun stayed in the newly bought house.

In the middle of the night when no one was around, I first modified the power grid at home, then built a base station antenna on the roof and installed the base station on the roof.

Because there are many factories nearby and the power of the public power grid is quite large, connecting electricity from home will not seem to consume a lot of electricity. When I have time in the future, I will find someone to build a chimney and then install the antenna on it.
