Wan Ling is the originator of domestic ship design, but no one who meets him can connect him with the old expert, he is more like a happy old man, usually always carrying a student-like backpack, the bag always contains a few books, from professional books to online novels, all-inclusive, according to his words: "The disciplines are the same, from this discipline can often see the shadow of another subject." ”

In the evening, Lin Yuan went to pick up Wan Ling, who came by helicopter, and saw Wan Ling wearing a robe and carrying a cloth bag on his shoulders, getting off the helicopter unhurriedly and walking towards Lin Yuan.

Due to the increasing contact between the personnel on the Beijing ship and the locals, Lin Yuan stipulated: When you need to carry modern items, you must use the items of this era to package it, so the Beijing ship ordered a batch of cloth bags, but this kind of bag is carried on one shoulder, Lin Yuan knew that Wan Ling must have sewn a strap on the bag and turned it into a backpack.

Wan Ling walked up to Lin Yuan humming a song, took the earphones out of his ears, and said, "Xiao Lin, did you call me here to let me help design the boat?" ”

Lin Yuan nodded and said, "Time is pressing, and I don't have time to write you a design technique task book, so I'll give you a brief description of my requirements." "The design technical task book is proposed by the ship use department, which is the starting point of the ship design, which stipulates the navigation area of the ship, the purpose of the ship, etc., and the design department completes the design of the hull in accordance with this task book.

Lin Yuan continued: "I originally wanted to build an inland river fleet to attack Sanchakou and Sanjiakou, but now that I see the situation of the Jilin Machinery Bureau, I want to build one or two small boats first, and use the method of sneak attack to knock down Sanchakou first." So I want the ship to be as big as possible, to fit as many soldiers as possible, and to put the Grimm Cannon on it and increase the firepower! ”

Wan Ling looked at Lin Yuan like a monster and said in surprise: "This is impossible!" ”

Lin Yuan thought to himself: "This request is very simple, how can it be impossible!" Lin Yuan hurriedly asked.

Wan Ling said: "The first step in designing a ship is to calculate the weight, in order to determine the displacement, with this you can choose the following design parameters, the weight of the personnel in the weight is an important part, I know how many people the ship has to carry to know the weight of the road, you give me a load as many soldiers as possible, what should I do!" Lin Yuan smiled apologetically and said, "Then load fifty soldiers and two Grimm guns, but if there is something to hide them, our situation can only be a sneak attack." ”

Wan Ling nodded and said with a smile: "This request of yours is very simple, and it is not complicated to implement, but before designing, I have to do one thing first." Lin Yuan asked, "What are you going to do?" ”

Wan Ling said: "You find me a craftsman, who is most familiar with ships." ”

When he arrived at the shipyard, Lin Yuan found a craftsman, the one who answered him during the day, Wan Ling looked at the young craftsman and said with a smile: "Please take a seat." ”

No one will feel the slightest sense of oppression in front of Wan Ling, a kind and kind old man, and this craftsman is no exception, Wan Ling lowered his head, took out a pen and paper, and began to draw something on it, asking while drawing: "What's your name?" ”

The craftsman replied, "My name is Zhang Dahe." ”

Wan Ling asked again: "Why do you learn to build ships?" Zhang Dahe said: "My father knew the master of shipbuilding, so he asked me to learn from him, saying that after learning shipbuilding, he would be a carpenter, and he would have a craft, and he would not starve to death anywhere." ”

Wan Ling chatted about family life sentence by sentence, as if he was picking a son-in-law, Lin Yuan thought to himself: "Don't talk about this, hurry up and talk to him about shipbuilding." ”

At this moment, Wan Ling picked up the piece of paper, put it in front of Zhang Dahe, and said with a smile: "Do you know what this is?" Lin Yuan also leaned over to look, but the room was using an oil lamp, and Wan Ling's hand happened to cast a large shadow on the paper, and Lin Yuan couldn't see what was drawn on it at all.

Zhang Dahe looked at it for a long time and said, "I know, it's a bare-pole boat." Lin Yuan thought to himself: "What is a light pole ship?" ”

Wan Ling nodded, wrote something on the paper, and then pointed to one of the places and asked, "What is this?" ”

Zhang Dahe replied firmly: "Keel." ”

Wan Ling pointed the tip of his pen to the side and asked, "What about this?" Zhang Dahe replied: "It's also a keel." ”

Wan Ling asked, "Are you sure?" Lin Yuan said loudly in his heart: "I'm not sure! What are you doing all the time? ”

Zhang Dahe hesitated and said, "That's what Master taught us, isn't it?" ”

Wan Ling nodded and said with a smile: "Yes, that's it." In this way, Wan Ling asked for half an hour, and then asked, "What kind of wood do you use to build ships?" ”

Zhang Dahe said: "They are all pine trees, and the trees are 50 years old. ”

Wan Ling said, "Okay, you go back and rest." ”

As soon as Zhang Dahe left, Lin Yuan asked, "What were you doing just now?" ”

Wan Ling put the paper in his hand in front of Lin Yuan, Lin Yuan saw it, and he understood why he called it 'light pole ship', 'light pole' means only one, Wan Ling drew a schematic diagram of the hull structure, which is the skeleton of the hull, as for the buildings above the deck, engines, propellers, etc., they are all outfitting contents, and they are not involved in this picture.

Wan Ling said: "The reason why I asked him this is because I want to determine the name of the hull structure in their era, just like the keel, which is the beam that runs through the bow and stern, in modern ship design, the middle is called the inner keel, and the side is called the keel in the side, they are all called keels in this era, and I asked them about the materials they use, and according to the strength and stiffness of pine, you can determine how long the boat can do." ”

Lin Yuan asked again, "Then have you figured out how to design it?" ”

Wan Ling smiled helplessly: "There has never been a ship orderer like you, many of the design parameters of the ship can not be selected at one time, and the general ship design takes a considerable period of time, but according to your meaning, we just build two ships for emergencies, so it is possible to build them." ”

Lin Yuan smiled and asked, "Do you want to draw drawings?" ”

Wan Ling shook his head and said: "The overall drawing, the parts drawing, the assembly drawing, one by one must not exhaust me to death, those craftsmen are very smart, I just tell them directly." After speaking, Wan Ling pointed to his head and said: "Captain, the width, the draft, the parameters of the ship shape coefficient, and the structural layout plan are all in my head, and after three days, I guarantee that you will form a satisfactory river fleet." ”

Lin Yuan believed in the strength of Wan Ling and the craftsmen, and these ships were very simple to build, there was no steam engine, no propellers, no watertight cabins, and there were still many materials that had been formed in the warehouse, so Lin Yuan was relieved to arrange the personnel, the soldiers of the second brigade of the new first division were all fishermen, and they were no strangers to rowing and rudling, Lin Yuan quickly selected two hundred soldiers.

Three days later, the four ships were built, and Lin Yuan on the one hand let the soldiers get on board the ships for adaptation training, and on the other hand, he ordered the new 1st Division and 1st Brigade to launch an attack on the three forks.

With the lesson of the fiasco of the Great Black Mountain, the Russian army at the fork in the road no longer dared to be careless, and the officers ordered their subordinates to dig trenches and repair fortifications, and the battle situation between the two sides was stalemate for a while.

Lin Yuan's river fleet, at this moment, quietly sailed to the rear of the three forks!
