Calculating a distance of 1,200 miles, and at the speed of the baggage train, it would take at least ten days and consume food and fodder. It would be good to be able to transport 30 to 40% of the food. "
"But if it's transported by rail, it only takes about five days."
Yang Gan exclaimed, "How is that possible? You're letting the horse run to death, and it can't run so fast."
Lu Liangjun chuckled, "Your Majesty, you don't know something. The track is divided into two parts, with sleepers in the middle. The distance between the sleepers is placed according to the proportion of the horse's eyes. Once the horse starts running, it cannot stop and will keep running at a constant speed. .”
"In addition, after the baggage trains are placed on the track, the weight is greatly reduced. Build a post station every fifty miles, place 10 to 50 people, change horses, and continue running. Because the track is an arranged track, if it is critical, you can run at night. That is The speed may not be as fast as during the day."
Yang Qian and Zhang Yumeng looked at each other.
"Brother, are you kidding? This is a black technology."
Yang Gan took out a charcoal pen, wrote and drew on the linen, and then handed it to Lu Liangjun.
"I'll allocate you another 50,000 people. Don't tell me enough. Take a look at the changes I made."
Lu Liangjun took a closer look and suddenly took a breath of cold air, "Sir, iron for the track? This, this is really too expensive."
Yang Gan smiled and said, "You don't know this. For us in Yuntong County, the smelting of steel, not to mention iron, is very common. As for the sleepers, they are made of cement, which can reduce the cost and time a lot." .”
Zhang Yumeng suggested, "Among them, baggage trains can also be modified. The wheels can be replaced with special wheels with a concave center that fits right into the track. The wheel hubs can be replaced with bearings. In this way, the horses can be made more relaxed by more than 30%."
Yang Gan asked curiously, "What is a bearing?"
"You're stupid. On the old bicycles, the round thing in the middle of the wheel hub had steel balls in the middle of the two circles. Not only was it durable, but it also made the carriage pole rotate like silk. So smooth."
Zhang Yumeng said and gestured.
"Fuck, how much money did Dove give you? If you advertise like this, I, Ferrero, will pay double."
Zhang Yumeng said, "It's actually very simple. I'm going to the foundry tomorrow. It's time for them to try casting large objects. It just so happens that the rails can be used to practice. Wherever they are inappropriate, they can be modified."
Yang Gan worriedly said, "I'm afraid of iron things now. If they are exposed to wind and sun every day, it will be troublesome if they rust."
"Snapped!"
Zhang Yumeng snapped her fingers, "Just use high manganese steel."
"Brother, stop making trouble. In ancient times, high manganese steel was very noble when it was named like this." Yang Qian spread his hands, thinking that this might be the case.
Zhang Yumeng narrowed his eyes and said speechlessly, "What are you thinking? This thing just sounds noble. In fact, this thing is very commonly used, such as wear-resistant machine parts, rails, and bridges."
Zhang Yumeng raised his head and showed a thoughtful expression, "The temper of manganese steel is very weird but very interesting. If 2-3% manganese is added to the steel, the low manganese steel produced will be as brittle as glass. Just break."
"However, if more than 13% manganese is added to make high-manganese steel, it will become both hard and tough. If the toughness is not enough, some indium can be added."
Zhang Yumeng paused and said, "Forget it, there is no need to add indium. This thing is more troublesome. It requires a centrifuge to refine it. Alas, it makes me cry if I talk about it too much. If it was in the previous life, I could just buy some."
Yang Qian asked doubtfully, "The high manganese steel you mentioned, is it really that simple?"
"It's that simple. In fact, many things can be created in ancient times. There are also many things. As long as you light up a foundation on the technology tree, you can light up part of the technology tree."
"It's a pity that we can't make a lathe for the time being. If we can make a lathe, we may skip the steam age and enter the industrial age. After the phone is developed, I will try to make the most primitive lathe."
"Hey, I don't care about anything else. The phone is the most important thing. You have to take care of it." Yang Qian warned.
"I know."
Yang Qian began to arrange for people to send official documents to Taihuang County. The purchase of cotton required Tian Zong to handle it.
What makes Yang Qian depressed is that the domestic canals are small, and shipping can only transport goods along the Chuanyun River or its branches. Although there are detours in some places, the consumption is very small, and the cost is only one-twentieth of land transportation. .
Each step is very cumbersome and requires the joint cooperation of multiple departments. Orders are conveyed from the mansion to various important departments.
"Yu'er, do you know where someone can build a ship?" Yang Gan had no choice but to ask after thinking for a long time.
So far, he has never seen a ship. Yang Gan just likes cold weapons. Although he also knows some about sea-going ships, to be honest, his knowledge is limited. So far, he has not even understood the weight unit of ancient sea-going ships. .
For such a professional matter, you still need to find professional talents. Yang Gan can guarantee that in Douyin, at least nine out of ten anchors who talk about history do not understand sea-going ships.
Xiao Yu thought for a while, shook his head and said, "Sir, we are in the north. Not to mention boat building, not many people can even swim."
Yang Gan crossed his arms and came to the sofa, lying down and thinking. He had never thought about the geographical location.
If we put it in the Three Kingdoms period, it would be the Wei State. The Battle of Chibi was just a group of northerners fighting southerners on the water. As a result, the wife Cao was almost killed.
At this time, Mu Qing said, "Yang Qian, why don't you go to Xinhuo Academy and ask."
"Since this period of time, many famous people in the world have come to the academy to apply for wives, and many of them are from the south."
When Yang Gan heard this, it made sense, and he was nestled in the study and hadn't gone out for several days. It seemed like it was time to go out for a walk. If he came back early in the afternoon, he could take a medicinal bath.
Do whatever comes to mind. This is your own territory anyway. After Yang Gan stood up, he walked towards the elevator.
Mu Qing immediately stopped him and asked, "What are you doing?"
Yang Qianqi said, "Let's go to Xinhuo Academy."
Mu Qing shrugged and said, "Yang Qian, I suggest you take a look in the bronze mirror."
Yang Qian was stunned and came to the bathroom. He almost shocked himself and touched his cheek. Although he didn't have a beard, his face was still very rosy, but his head was like a chicken coop.
Feeling anxious, he couldn't wait to take a shower, so he asked Mu Qing to help him untie his hair, apply hair oil on it, comb it smooth, tie it up, and then ran out the door.
He got on a black BMW and ran towards Xinhuo Academy.
Not long after, Yang Gan arrived at the Xinhuo Academy in a hurry. As soon as he entered the door, he was stunned.
In Xinhuo Academy, the voices of several masters arguing came from the office.
"Well, actually, if you ask me, ordinary people don't need to read or write. After three years, they still have to go back to farming."
"Hahaha, you don't know this. Many students come in just for two meals a day and a roof to cover themselves."
"Oh, I have studied Confucianism for most of my life. When I arrived at Xinhuo Academy, I found that the Confucianism here is completely deviant. There is also a woman enrolled in the school. This, what is this?"
"Then you don't know that the two barbarian women around Lord Wu An fought with him and made great contributions in annihilating three tribes, so there is a precedent for allowing women to enter school."
"Just letting merchants and their like study, this, this is too much. Then, wouldn't we be no different from merchants and their like? Why are we studying?"
At this time, a firm and confident voice came from outside the office.
"The purpose of reading is to establish a heart for the world and to carry forward the past and open up the future."
"Establish a destiny for the people and show great love."
"To carry forward the unique knowledge of the saint and continue the cultural context."
"To create peace for all generations and to express feelings for the family and the country, what do you think, Masters?"
Everyone chewed it carefully and were suddenly shocked. It was such a profound understanding. No matter what the doctrine, you must first be able to read. Otherwise, if you don't even know the words, how can you read the meaning of each doctrine?
A handsome figure appeared at the door of the office, looking at everyone with a smile on his face.
Yang Qian quickly walked inside, lifted his robe, knelt on the ground, and kowtowed heavily to Tan Tianyan.
"Teacher, my disciple is unfilial."
Tan Tianyan, who was sitting in the first seat, stroked his beard and said with a smile, "You kid, are you doing such a big courtesy today? How unfilial are you?"
After Yang Gan stood up, he said, "First of all, it's unfilial. I haven't seen my mentor for a long time. Second, I have appointed another person as my mentor. It's the formal kind of kneeling three times and kowtowing nine times."
The ladies looked at each other, and they all looked at Tan Tianyan. In this day and age, if you study in the academy, it is almost the same as being in school, and you won’t be able to use the connections of the master.
But according to the rules, the relationship between a father and his son is deeper than that between a biological father and his son.
Tan Tianyan's expression gradually became serious, "You don't come here often, but I understand that you are very busy. You are in charge of all the internal and military affairs of Yuntong County."
"Since you take someone else as your teacher, there must be a profound meaning behind it?"
Yang Gan nodded and said, "The more time my disciple spends on the battlefield, the more he feels that his martial arts has stagnated. This time I met a woman in Dongde County who was far better than me in strength and martial arts. Zi said three Everyone must have a teacher from me, so I worshiped her as my teacher."
Several wives began to whisper among themselves again.
"How can I take a woman as my teacher?"
"Yes, this Lord Wu An is not bragging, is he? He can't even defeat a woman, and yet he claims to be the bravest of all three armies."
"Who is this woman's surname?" Tan Tianyan was particularly satisfied with his disciple and didn't mind him having another master. However, in order to prevent others from delaying him or even coming up with bad ideas, he still asked Yang Gan concerned.
"My master's surname is Cao, his given name is Wushuang, and he is a descendant of the Yue Kingdom."
Suddenly everyone showed a clear expression, and Tan Tianyan suddenly said, "I didn't expect that she was a disciple of my old friend. It is fate that you can become a disciple of her. Yang Qian, you should study hard. Mr. Cao should have the Qi training skills of the Yue royal family." Law."
Yang Gan smiled and said, "I have learned it."
Tan Tianyan's eyes widened and he couldn't help but curse.
"Fuck~~~!"
