This time, Yao Ran originally wanted to explain to Yao Huo, and before he left, the popularization of the steam engine and the construction of railway transportation were carried out. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The steam engine is not bad, as long as three places are coordinated, the construction can be completed, the first is of course the iron ore field, the second is the supply of coal mines, and the third is the operation of the blast furnace camp, so as to complete all the work desired.

But railway transportation, as well as the widespread use of steam engines, were not so easy. First of all, the transportation of the whole steam engine is a huge problem.

Although the whole steam engine is not particularly huge, the mass is extremely heavy, and it is very easy to transport. The simpler way is to transport the various parts of the steam engine before assembling them to the designated location.

Then the blast furnace camp will be installed by people, which is flexible, and also reduces the difficulty of transportation, and transportation costs, and most importantly, can reduce the failure of the steam engine caused by the bump of the whole machine during transportation, and it will have to be overhauled again after delivery.

However, the follow-up popularization of the steam engine was a huge project. There is also a lot of technical work, such as the transformation and utilization of some equipment, and the largest use should be crushing, or grinding applications, such applications are not difficult.

Even if Yao Huo wanted to apply the steam engine to the crane before, it was not difficult. The difficulty lies in the control method of the equipment after connecting to the power, and here Yao Ran needs to explain something to Hua Tuo in detail.

Today is the day of the completion of the second blast furnace, and before Yao Ran leaves, he has to supervise the construction of the huge steam locomotive. Another job is to teach Yao Huo more ways to use steam engines, that is, various application methods.

The three big disciples gathered again in front of Yao Ran to listen to Yao Ran's lecture, although a lot of time has passed, but the state has not changed, Hua Tuo is absent-minded, Yao Huo, Xiaoping is fascinated by listening, Xiaoping's thinking jumps, Yao Huo is calm and steady.

A piece of white paper, on the blackboard behind Yao Ran, was clamped by Hou Yun's help, and as Yao Ran's spit flew sideways, the pen walked away, and the drawings also appeared in front of the three apprentices.

Tracks, transmissions, gears, timers, speed counters, drum brakes, reciprocating transmissions, and so on, leap onto the paper under the warm and equally yellowed light.

It doesn't matter if Hua Tuo doesn't like to listen to these things, because Hua Tuo does have a lot of work to do, Yao Ran is not reluctant, but Hua Tuo still likes to be with the other two senior brothers, and he can't understand the days together.

Of course, it's not completely incomprehensible, some deconstructed division theories, you can still listen to it, after all, I've been listening to it for a long time, and what I don't understand is mainly in some principles, just like a transmission, how to change the speed in a big trap and a small circle.

And then there's that drum brake, how can you make something that big slow down and stop when you highlight a point. Didn't the teacher just say that the greater the mass, the greater the inertia? How to stop when the inertia is large.

Of course, Hua Tuo has his own philosophy of life, if he is not interested, just listen to it, and do not drill the tip of the horns, but there are two people who like to drill the tip of the horns at the moment, thinking hard, looking at the drawings drawn with black pens on the blackboard on half of the white open white paper, and on the other side is the details of the decomposition and explanation drawn with white chalk on the blackboard.

Explaining these things, Yao Ran knows that there is a risk here, because there are many design drawings and schematic diagrams, he can only explain the principle to them, if they start to study and produce after they leave, if it is just an experiment, there is no big problem.

However, if it is put into production, and then the production is reduced due to the instability of the equipment, it is a small matter, and if the equipment fails, causing casualties, it will be a little more than worth the loss.

But there is no way, these things, those who should be self-reliant should rest assured and boldly let their apprentices break through, if everything is done by themselves, Yao Ran will really be tired to death.

Because these things are not a demand for one or two, on the contrary, these equipment is a key to the industrialization progress of the entire Yao clan, if the industrial products have not been fully marketed in the entire Yao clan now, the benefits to Yao Ran, or the benefits to the Yao clan are, immeasurable.

A large number of industrial products can be provided by the Yao clan for the exchange of weapons for the population to win over other tribes, and the industrial products produced in batches can also quickly arm a large number of people.

This time he went to Daxue Mountain, Yao Ran was going to let the two departments of the casting workshop and the stamping workshop stamping a batch of more than 100 iron pots for himself, and then he would go to get the barbarians' chassis to exchange the population personally, if it went well, one pot for two people, if it didn't go well, these iron pots could also be used as shields in the event of a conflict.

The master and apprentice had a long talk, and the entire courtyard of Yao Ran's office was brightly lit, and one lasted until midnight, if it wasn't for Hua Tuo falling to the ground on the stool sleepily, Yao Ran might have to continue to talk for an hour or two.

Because the foundation of the Yao clan is too weak, there is no industrial foundation to talk about, and directly jump into the pit of industry, there are too many things that need to be made up, otherwise it will only be passively made up for the class, and once anything is passive, there will be no good results.

The three disciples were arranged in the wing room in Yao Ran's courtyard, but after saying that they were going to sleep, Yao Huo and Xiaoping were really sleepy, and they wanted to fall asleep. Began to study his own notebook of herbs.

As a result, it didn't take long for it to come out of Yao Ran's office, the moaning of the woman and Yao Ran, Hua Tuo once again despised his teacher's aesthetics, and then found two balls of hay and stuffed them on his ears.

When I woke up the next morning, Hua Tuo and Xiaoping were no more, only Yao Huo was still sitting in front of yesterday's blackboard, and there were still a few design drawings behind him, after asking where the two were.

Yao Ran learned that Hua Tuo had a lot of medicinal materials to be processed, and Xiao Ping went to find someone to make the tools he wanted, after all, the purpose of his visit this time was to make efficient mining tools.

Because of the mining work, it is dangerous, dirty, and tiring, but fortunately, among the slaves of the entire Yao clan, only the slaves in Daxue Mountain can order food, and what they want to eat can be directly said, the food can fully meet the needs of the miners, of course, it is not okay to eat human flesh.

This is also instructed by Yao Ran, although Yao Ran has not experienced the hard work of miners, but in his past life, Yao Ran has seen a lot of related film and television works and news, and they stay in those dark spaces, and the danger factor is too high. After a long time, it is easy for people to hallucinate, or get some mental diseases.
