Xiao Ming followed Su Caier to Richanglong's business in Xiuzhou City, which is a relatively large house, and there is still a shop on the street side, but this shop sells antiques, calligraphy and paintings.

The owner of the shop is surnamed Jin, and his brother is the shopkeeper of the Xiuzhou firm in Richanglong, and he himself is the master of the Mo family, that is, Uncle Jin in the mouth of Shen Bei'er, the weaving factory of Richanglong in Xiuzhou is not huge, but it is the largest purchaser of raw silk here, and even he has opened up hundreds of acres of mulberry garden, raising silkworms and reeling silk is the main business project, relying on them to live thousands of silkworm farmers, at the same time, Richanglong is also here to carry out the printing and dyeing business of cooked silk, producing a lot of beautiful color lines.

Xiao Ming's arrival made Su Bi overjoyed, took his hand and dragged it to the inner hall, the inner hall was messy, this is the laboratory of Su Bi and others, Su Bi wore an apron sleeve, completely dressed as a carpenter, in addition to him, there are several people here, "Twelve-fingered Divine Craftsman" Song Wu is also among them, and several craftsmen are all craftsmen of the Mo family.

During this time, these people have been in this room, delving into some key problems of power looms, but they can't find a breakthrough for a while, and the development is in a state of stagnation.

Xiao Ming originally told them that he could only draw drawings and would not make utensils, but he had a natural sense of decomposition drawings, or he would not be able to draw exquisite three-dimensional drawings.

In fact, the problems they encountered were nothing more than two kinds, the first one, the problem of power supply, this last time Xiao Ming proposed to use animal power, but it could barely be solved, the second type, the problem of power deceleration, the prototype of the loom has been made of wood, but this is designed in the case of the use of manpower, not the drawings provided by Xiao Ming, the manufacturing of the model These people have fallen into the old way of the original formula, and the transmission of power is still using various meshing gears.

Xiao Ming soon discovered the problem, the use of Mo's mechanism for gears is almost perfect, which can be seen clearly from the shock absorption mechanism box under their carriage, but for a device that only uses reciprocating motion such as a loom, a large number of gear mechanisms will only waste a large amount of kinetic energy.

During the Industrial Revolution, Britain was the first to use the steam engine in the textile industry, and they used large pulleys to drive the crankshaft to reciprocate, which improved the efficiency of labor I don't know how much.

Since it is a drawing, Xiao Ming does not need to play with axes, chisels and ink fountains, the carpenter work looks fun, but it is very tiring, Xiao Ming found a blank paper and drew his thoughts directly on the paper, Su Bi and others watched, and some people were whispering. Xiao Ming didn't care about him and buried himself in the pictures.

Then he explained to everyone how to use large wheels, with belt conduction, drive small wheels to drive the crankshaft to swing, how to disperse the power to different looms, and for the problem of deceleration, he drew a few strange gears on the figure, this kind of gear is beveled, small wheel sleeve large wheel, indicating the center involute, the groove surface of the cogging is adjusted by worm, and several gears of different sizes can be manually adjusted to achieve different speeds.

After talking about things, everyone else was a little dazed, but Song Wu was worthy of being a great man of ink, and after thinking for a while, he added his forehead with his hand and said: "Good idea, good idea!" Hurry! You come with me, let's make a model now" After speaking, he turned his head and ran, like a smoke, Xiao Ming smacked his lips when he saw it, "Frankenstein is basically like this, right?" He muttered.

Su Bi also figured it out at this time, and couldn't help but be happy that his beard was curled up and praised Xiao Ming, and then pulled Xiao Ming to sneak back, and then let Xiao Ming watch his idea of using steam power, this thing has been bothering him for a long time, since Xiao Ming did the boiling water experiment for him, Su Bi felt a flash of inspiration in his mind, but he couldn't grasp the main point, and countless drawings were drawn, and he was always not satisfied.

Xiao Ming saw it, and fell into a misunderstanding again, Su Bi thought of the gas power of steam, not the power of compression, the diagram he designed was to use a cauldron to boil water, and then draw out a mouthpiece from above, facing a large fan-like blade, using steam to blow the blades to work.

The working principle of the steam engine is the use of steam gas power compression principle, the huge expansion of water vapor after being heated is the basis of all workmanship, which contains a lot of modern scientific and technological achievements in it, including: materials, container sealing, piston and cylinder and so on.

From the preliminary understanding to the personal experiment, Xiao Ming also participated, but he found that the difficulty in this is not generally unimaginable, first of all, he is not familiar with the work methods of ancient Chinese craftsmen, and the steam engine has very high requirements for materials, without a modern industrial base, it is basically impossible to complete, this is not a simple experiment a few times, so Xiao Ming is very frustrated.

He went back and tried his best to check the information, but the information in Ding Jianpeng's computer was still very little in this regard, and no modern person could discuss it together! Xiao Ming couldn't help but miss Ding Jianpeng a little, I don't know where this guy is now, has the saltpeter mine been found? If saltpeter can be found, the development of explosives can begin immediately.

Xiao Ming considered that the production of explosives must have a basic chemical industry system, which must be established, and the personnel, funds, and technologies involved need to be solved, and he also needs to solve the process problem of metal materials, which can be relied on by the iron factory, and Ding Jianpeng seems to be a chemical and man-made materials major, and he has to come to engage in scientific research.

Xiao Ming wrote a few words on the paper: "Meritorious service", then crossed it out, and wrote: "Xiangche Beauty" grinned and crossed it out, and then wrote: "Settle down" was crossed out again, after thinking for a long time, Xiao Ming wrote down four words: "Freedom to survive" These four words can also be understood as "freedom of survival" is Mr. Survival and then freedom, or first freedom and then survival? After throwing down the pen and paper, Xiao Ming pondered hard in the room.

Gu Xiaoliu was very strange, although he recognized a few words, he couldn't recognize the simplified characters written by Xiao Ming, and he didn't dare to disturb Xiao Ming, so he had to wait on the sidelines, watching Xiao Ming go around the room like a wolf.

Xiao Ming stopped suddenly, and then lay on the table and wrote, this is his specialty, called: "Logical backwards method", he thought that if you want to survive freely in the Great Song Dynasty, you must integrate into the entire society of this era, and get the support of those in power, so you need strength, what do you rely on to gain strength?

The problem was a little complicated, Xiao Ming was a little bored, threw the paper into a ball, and then wrote: "Bow to Lao Tzu!" Grinning: "That's the strength".

Write down: fists, guns, cannons! "That's right! I want to build a cannon" Xiao Ming said, and then pushed it backwards, if you want to build a cannon, you must solve the problem of the sealed barrel, this can be cast in bronze for the time being, so where is the breech or the rear boring? Leaving it aside for the time being, shells need explosives and propellants, this is a bit close, what are shells used for? - Cast Iron! It should work, what is the purpose of the projectile? - Nitrocellulose! Or saltpeter is needed! What are charge cartridge shells used for? Thick cardboard should be fine, and it seems that the paper industry still needs to be developed...... It's a little messy, but you can still push it backwards.

There are several kinds of ores, from the current point of view, the urgently needed several are saltpeter ore, iron ore, copper ore, quartz ore, coal mine, silicate ore and so on.

The big grenade used to defend the city last time was good, and it can be miniaturized as a grenade, how to solve the problem of pulling strings? Then you need quartz and glass powder, glass is not even invented by the Arabs at present, Xiao Ming thinks it is just burning? Find quartz ore and burn it directly, burn out the silicate and burn the cement ......! Thinking of cement, Xiao Ming smiled.

Pushing it backwards is two simple science and technology trees, it is easy to do it with ideas Xiao Ming thought, this is the same as writing a novel outline, with a goal to find a solution, for example: "In the Song Dynasty, Taoism declined, but there were many folk scholars, these people's alchemy is the basic metallurgy and chemistry, just find some such people, there are records in the encyclopedia of ancient Chinese science and technology, in the Tang Dynasty, the alchemist Gu Gangzi recorded in his book "Yellow Emperor Jiuding Shendan Sutra" volume 9 "refining stone gall extract essence", That is, dry distillation of stone gall (bile alum) to obtain sulfuric acid, with sulfuric acid it is even better, many metal elements can be refined, and the prototype of the metal material industry will come out.

The people of the Song Dynasty attached importance to industry and commerce, but the overall status of the craftsmen was not high, in order to develop basic industries, a large number of knowledgeable craftsmen were indispensable, just like those craftsmen of the Richang Longmo family, these people are extremely intelligent talents, Xiao Ming needs to slowly improve their social status, there are many systematic work to do, but there is one thing Xiao Ming believes, that is, the wisdom of the Chinese in this era, many things can find solutions, he must believe in the craftsmen, It's like believing in the craftsmen of the Richang Longmo family.

Facts have proved that Xiao Ming guessed correctly, the craftsmen of the Richang Longmo family are indeed extremely smart, because they made a primitive model of a steam engine, and one day a few days later, Xiao Ming was invited to observe and learn.

A nineteenth-century monster is now tossed out by a group of Chinese craftsmen in the twelfth century, Xiao Ming looked at the monster in front of him with great interest, this is a semi-circular thing, a cauldron filled with water is connected to a piston cylinder made entirely of copper skin, driving a crank, and a large wheel is connected to the crank, the cauldron is placed on a masonry stove, the bottom is full of firewood, the fire is very strong, after a while, the water in the cauldron is boiled, and the steam generated enters the piston chamber, slowly pushing the piston forward, And gradually accelerated, the crank drove the wheel to start to rotate rapidly, the whole steam engine was unusually simple but very efficient, and the craftsmen of the Mo family even made a vent pipe used to excrete excess steam!

Xiao Ming was surprised: "How did you solve the sealing problem in the piston cylinder?" He asked.

Song Wu smiled and took out a small boat model, and said to Xiao Ming: "This is a model of a water boat made by Master Jin, in fact, the Mo craftsmen have already solved the problem of sealing on the liquid pressure transmission, the key difficulty is not here, the difficulty is in the angle of the crank and the piston The problem of linking, which involves a lot of calculations, thanks to the girl in the bottle, she really mastered his father's experience in the study of mathematics!" ”

Xiao Ming nodded, and Song Wu said to a person behind him: "Bottler also helped me calculate the position angle of the hydrodynamic boat, which is really embarrassing for her, but if my hydrodynamic boat can use this kind of power, it is estimated that the sails will be eliminated!" Haha"

Xiao Ming suddenly turned his head and glared at the man: "You are the master gold!" Ahh As he spoke, he pulled out the strip of cloth from his bosom.

To be continued, the novel is fictional, and many technical terms and data are nonsense, please don't shoot bricks according to the flow! Thank you! **********
