With Shu Han's words as a guarantee, the fishermen present finally stopped trembling so much, and they stood trembling, but after all, they had a low status, they belonged to the marginal characters of Black Iron City, although they were not slaves, but they were not much different from slaves, their skin was completely different from the nobles in Black Iron City, their dark skin proved their hard work, and the wrinkles and rough skin on their faces were obviously only thirty years old, but they looked like a little old man of sixty or seventy years old, and they were even shorter than Shu Han.

The hardships of life have bent their waists, and most of them are pulling and straddle when they walk, begging for life in the water all year round, and the parts below their waists are often wet, and they have been like this for many years, resulting in a large number of problems in the lower body, and there is a mustard disease between the legs, and they can only walk with their legs open, like those samurai who ride horses, with lap legs, and their faces are cautious expressions, which look inferior.

Shu Han didn't dare to say anything, he was afraid that he would scare them with a word, so he attached his plan to it, and at the same time asked Zhang Song to take out the drawings he designed to show them.

"This is? Fishing net. A fisherman said with some skepticism, from the appearance, it is indeed a fishing net, but it is not quite like it, because it is so big, a length of several hundred meters, they have never seen such a large net, but from the appearance, it is indeed a net.

"Yes, old gentlemen, look at this net, as well as this series of equipment, runners, tugboats, rivets, punchers, Zhang Song, bring them up." Shu Han instructed, soon these tools were brought up, and now Shu Han wants something in the Black Iron City, almost all of them can be delivered as soon as possible, even if they don't, they can also be ordered to blacksmiths and carpenters to make them.

Therefore, at this time, through Shu Han's order, many things have been found, but the size is not yet satisfied, after all, Shu Han wants to drag the fish and shrimp of the whole lake, which is not a gadget, so it must be remade, but there are still small pieces, so they will be taken up and let the old farmers see first.

"Well, it's too big, and we've never fished like that." An old fisherman spoke, Shu Han smiled and said: "Yes, but now the situation in the Black Iron City is critical, and we can only use dead horses as live horse doctors, this method is found from ancient books, the design drawings are given to you, you take them back to take a good look, these days, you live in the barracks, everything, you just tell the soldiers to do it, three days, find out some of the drawbacks here, as long as this fishing is successful, I will go to the municipal government for you, and ask you for credit, how about it." ”

The faces of the fishermen are still a little hesitant, although the reward proposed by Shu Han is very covetous, but also to see if they have this ability, they used to fish through small nets, or when there was no freezing, now the lake is frozen, fish and shrimp are living at the bottom of the lake, which is completely different from ordinary fishing, how to change the sinking way of desire, and at the same time catch a large number of fish, this is to have the ability.

Many old fishermen are a little hesitant, they really want to give it a try, but they really don't believe that the young military commander in front of them has not started yet, so they naturally say nice things, it doesn't matter if they don't succeed, but if they really don't succeed, who knows if this group of people will vent their anger on their group of powerless people?

This is something that no one can say, living at the bottom of the Black Iron City, they know very well what kind of virtue these superiors are, so everyone dare not agree, Zhang Song on the side was a little impatient, so he wanted to urge, Shu Han hurriedly stopped him, and then said to everyone; "Everyone, I know what you are thinking, and I can understand you, but I can assure you that your safety is absolutely safe, and even if you can't solve this problem, I will not embarrass you.

Two soldiers walked in from outside the door, one holding a tray in his hand, Shu Han stepped forward and picked up the red cloth on the tray, only to see that there was a whole plate of gold coins inside, shining and dazzling, the fishermen were suddenly attracted by this golden light, Shu Han said at this time: "This plate is a hundred gold coins, and the other plate is also this number, whether you can complete this task or not, these two hundred gold coins, you can take it now, and if you can complete this task, there are eight hundred gold coins, I will reward you, this is my sincerity, everyone, please give it to you. ”

The fishermen looked at each other, their hearts tilted, but they were still unable to make a decision, when a young fisherman shouted: "My lord, I don't want gold coins, if we can help you solve the problem, can you send me a wife?" ”

This voice made Shu Han stunned for a moment, and then he looked at it, and saw a young fisherman standing in a group of old fishermen, he was very young, so he was very low, and he was not conspicuous standing in a group of old people, so Shu Han didn't notice it, but when he looked carefully at this time, he found that this person was actually a young man.

Like his fathers, he has a dark face and a thin body, but his eyes are bright, his messy hair looks very energetic, although his body is thin, but it is a piece of muscle, very strong, and there are a lot of strangulation marks on his shoulders, which should have been left when he was sailing and hitting the net, Shu Han looked at him and asked with some doubts; "You are?"

"My name is Zhang Tianzi, my lord, you can't send a wife." The young man Zhang Tianzi did not have any fear on his face, and when he saw Shu Han asking, he stepped forward directly and reported his name, which made his father on the side frightened and hurriedly walked up, candle Zhang Tianzi's hand, and said: "You fool, don't kneel down quickly and admit your mistake, my lord, the son of a sin has a collision, please Haihan." “

Saying that, the old fisherman knelt on the ground, Zhang Tianzi was a little overwhelmed and knelt on the ground, but there was confusion written on his face, obviously, he didn't understand why his father knelt on the ground, didn't the person in front of him say that he would meet any of their conditions, he just put forward a condition, why kneel?

Obviously, this is a newborn calf who is not afraid of tigers, but Shu Han himself is not the kind of domineering person, he smiled and asked the old farmer to get up, and then said to Zhang Song beside him; "How did this kid let him in?"

"Well, when we went to their village, this Zhang Tianzi volunteered, saying that he was the most powerful fisherman in their village, very powerful, and many people around him also said the same, we thought, since the adults need an experienced fisherman, then this person is obviously competent, so we brought him back." Zhang Song hurriedly said on the side.

"Oh, he's still a good fisherman." Shu Han smiled and nodded, since this person has some real skills, he naturally can't deal with it at will, but looking at such a small child, he opened his mouth to ask for a wife, Shu Han didn't feel a little dumbfounded, and said: "How old are you, you want a wife, and your body hasn't grown yet." ”

"I'm fifteen years old this year, and I've reached the age of legal marriage, so why can't I get married." Zhang Tianzi said as a matter of course, Shu Han looked at him and said: "Oh, that's right, but since you want to get married, you can just find it yourself, if you can make this tool I need, you take the money, the girl in the village can go to propose, plus your good craftsmanship, no one will refuse you." “

"No, I don't want the girl in the village." Zhang Tianzi said categorically, Shu Han was a little surprised, and asked, "Why?" Zhang Tianzi said as a matter of course: "It's too ugly, it's the same as grandma and grandma, it's dark, I don't like it." “

This is really a bit direct, and it doesn't sound so good, and next to his father came up and slapped him on the head, saying, "What nonsense." Shu Han stretched out his hand to stop him and said, "Tong Yan is unscrupulous, uncle, please let me finish talking to him." “

"You don't like the girls in your village, so what kind of girls do you want?" Shu Han asked.

"I want the girls in the city, they are white and tender, I like them." Zhang Tianzi said bluntly, looking at such a very honest and funny child, Shu Han couldn't help laughing, and said: "Okay, as long as you can research this tool for me, I'll be a matchmaker for you and find you a wife, okay." “

"Okay, the gentleman is quick to say a word, and we will pull the hook." Zhang Tianzi raised his eyebrows, immediately stepped forward, stretched out his little thumb, at this moment, he is like a fifteen-year-old child, no, he is fifteen years old, but it is completely different from the appearance of rushing to have a wife just now, Shu Han doesn't mind, extraordinary people always have something extraordinary, for the sake of fishing, Shu Han doesn't mind so.

At the same time, he likes this kid a little, he is not very old, his tone is quite big, and he can directly talk about what he wants, although many people don't like such a person and think it is too direct, but Shu Han likes to deal with such a person, and he can say what he wants directly, and he can also do things according to the rules, so as not to be suspicious of each other.

After letting Zhang Song arrange their daily life, Shu Han began to deal with his own affairs, and in the next three days, these old fishermen really lived up to expectations, and there must be brave men under the heavy reward, in these three days, they first spent a little time to understand the process and feasibility of Shu Han's entire fishing operation.

At this time, the advantages of the Black Iron City system are shown, because everyone has been raised when they are young and has received the most basic education, so the simplest words and mathematical theories are understood, even if they are farmers, so when calculating this set of plans, it will be relatively easy and easy to understand, otherwise if it is a group of people who don't even know the words, even if they have experience, it is very difficult to understand the specific operating system of Shu Han's method.

In addition, they themselves have more than ten years of fishing experience, so after a day of discussion, they found that Shu Han's operating system does have a great possibility of success, but at the same time, they also found a lot of mistakes, first of all, relying solely on rotation and animal power, to drive such a huge fishing net, this is unscientific, if this net really wants to empty the vast majority of the fish and shrimp in the entire lake, then he will weigh at least fifty tons, such a huge weight, with the current ability of Black Iron City, You can't make a runner that can bear this weight.

Therefore, it must be changed, for this reason, Shu Han specially invited the professor of kinetics from the university to be responsible for the study of the new wheel, and finally designed a set of roller skating groups to ensure the use of the wheel, which also made Shu Han feel a little miserable, the knowledge of the roller skating group in junior high school and high school, but now it is the knowledge that only university professors can master, which shows how far the technology of the Black Iron City has shrunk.

In addition, in the rotation of the place, the fishermen also raised objections, that the net should not be directly on the ice, but should be carried out on the riverbank, the reason for this is because Shu Han's method, Chagan Lake is in the northeast, winter can reach minus 278 degrees, the lake surface freezes to a depth of more than ten meters, and the Black Iron City is located in the East China region of the original earth, even if the climate is extremely low now, the temperature will remain at about minus 15 degrees to 20 degrees, and now it has just entered winter, and it has not yet reached the season of heavy snowfall. As a result, the temperature will remain around minus seven or eight degrees.

This temperature, coupled with the fact that the lake itself is not stagnant water, is connected with the sea and big rivers, and the waves are turbulent, so the ice surface often does not exceed seven meters, and this level of ice surface cannot bear the huge weight of rotation, and must be placed on the lake surface, which must be improved.

After all, not all lakes can be installed on the shore of the runner, many lakes are some tidal flats, the rotation is put up, I am afraid it will sink, but also can not be too many stones, otherwise it can not grasp the balance, it must be equal, but also very hard, at the same time the place to hook up, can let multiple groups of roller skating at the same time, and also give the animals to work space, such a place is not easy to find, most of the lakes are surrounded by farmland, which needs to carry out some direction of transformation.

At the same time, the fishermen also raised objections to the fishing process of Shuhan, since it is to fish the whole lake, then it is not possible to cast the whole net and it will be over, because this is winter, a large number of fish are resting at the bottom of the lake, if you just cast the net, you can't catch a fish at all, because the fishing net is sealed on the top, but the bottom is free flowing, so if you want to catch the fish, you must let the fishing net stick to the bottom of the lake and go up, only in this way, can the fish be caught.

For this reason, the fishing net must be redesigned, at the beginning of the fishing net, two iron pieces should be placed to facilitate the sinking of the fishing net, and then use the fishing line, the iron net will be pulled under the net one by one, so as to occupy the entire bottom of the lake, and finally the fish will be fished up, for this reason it is necessary to make a lot of holes, so that these fishing nets can shuttle at the bottom of the lake, and drag with the fishing line, and for these holes, the fishermen also have their own opinions, all in all, three days, these fishermen use their own experience and wisdom, Shu Han's originally unreliable plan has finally been developed into a roughly detailed process, and it has a certain success rate.
