The sunshine of early spring shines warmly on the land of Jianghuai, and the land in the southeast of Chaohu Lake is full of vitality. In another year of spring ploughing, thanks to the guarantee of water conservancy projects and the good sunshine conditions on both sides of the Yangtze River, the farmers here fully expressed the virtue of hard work, which is in the bones of the Chinese. Since the peasants took the lion's share of the bumper harvest, each peasant commune took the initiative to arrange the work of its own group. The work of the agriculture group is only to inform and coordinate the maintenance and use of water conservancy by each group of advanced production experience.

Cheng Pan now implements a hands-off policy towards agriculture in his territory, because he no longer needs to promote the productivity of agriculture. At present, the administrative group does not reap profits from the peasants and basically maintains a balance between revenue and expenditure. In other words, a very small part of the grain in the public granary of the territory is collected from the field tax, and the increase in grain production has no direct impact on the increase in the tax revenue in the territory. But Cheng Pan knows that farmers are now a huge market. In ancient times, how did the commerce of Jiangsu and Zhejiang come about, not because they were shrewd but because of their agriculture, the wealth created by agriculture was greater than the local consumption of agricultural wealth, and the remaining wealth was accumulated in the people, and the people had purchasing power to form a market. Cheng Pan opened up exhibitions in other industries, the sales of iron utensils were gradually increasing, the scale of brick kilns was gradually expanding, and a large number of communes purchased building materials and built collective housing. The essence of the small-scale peasant economy is not the conservatism of the peasants, but the fact that the peasants really have no money in their hands. Industries that are now fed by agriculture are growing.

Business is now like a spoon that industry uses to scoop up nutrients from agriculture to replenish itself. It is a good habit to eat in the bowl and look at the pot, and the industry created by Cheng Pan is no longer satisfied with the market in his one-third of an acre, and the output of industrial products is a must. Looking at the world's industrial countries, what was the gold-absorbing industry in the early days of growth? That's right, the textile industry. Channels were excavated on the north bank of the Yangtze River, and giant water wheels were erected. The first historic innovation in the Western textile industry was the Jenny spinning machine, which was a low-tech thing that used shuttle technology, which was quickly overcome with the cooperation of several carpenters and weaving experts. Driven by the water turbine, there is no need to consider the limiting factor of manpower size, and at the same time, the high-strength material of steel replaces the wood as a component in the machine, and the internal strength of the entire loom is enhanced, so the scale is larger, and the time-consuming and laborious craft of weaving is replaced by the machine that combines iron and wood. The price of cloth plummeted throughout the realm, and merchants bought large quantities of cloth from the realm. Since there was no weaving group in Chengpan's territory, the birth of this industry did not take anyone's benefits, but the cloth merchants in the lower reaches of the Yangtze River will be affected, but they cannot encourage the weavers to come to Hezhou to smash the machine. In the process of industrialization, a group of people will always be crushed.

As the steel production in the steel mills became larger and larger, Cheng Pan felt that the current human-animal agriculture and hydro-powered industries could not consume so much steel, and new power had to be found.

Cheng Pan aimed at the technology of the steam engine, I have to say that this scientific and technological leap forward is a complete failure, the mechanical principle and mechanical structure is a simple problem, the prototype was quickly built, Cheng Pan watched this thing run, lit the fire, can move, but everywhere white gas, the sound and momentum, and ten pressure cookers put together a fight, but the output power is too low, an adult can stop the movement of the machine with his hands, counting on it to replace the hydraulic machine, waste coal. The people of the real yàn group quickly made improvements, this time they did not use willow nails as a link, but instead used tin-lead metal juice to weld the gaps, this dangerous work was done by Cheng Pan, and it was indispensable to use the power of the sun to weld the gaps. Cheng Pan uses the world's only human body welding method. In the end, the prototype was running again, and there were fewer air leaks elsewhere, but the piston still couldn't do anything. Modern industry uses vulcanized rubber for pistons, and rubber trees are still found in the primeval forests of the Americas. With the current navigation technology, it is not a dream for rubber. Without the rubber Cheng Pan wanted to use a substitute, the leather became a test product, the craftsman's craftsmanship was good, the machine was running normally, the air leakage was completely stopped, the steel torque of the steam engine became powerful with the rotation of the iron wheel, and the steam engine completely had the appearance of a steam engine. Before everyone could cheer, there was a muffled crash, which sounded the same as the sound of a popcorn stove on the street. I saw that the piston of the steam engine spewed out some waste leather slag. A hissing sound followed. It turns out that the leather is not as wear-resistant as rubber, and the leather on Cheng Pan's body is almost the same if you change it. It's a pity that Cheng Pan didn't have the fearless spirit of dedicating himself to science. If the leather is not good, then change something else, more than a dozen reliable materials have been replaced, and the best material is only a kind of cork, that is, the kind of cork that is now corked in hot water bottles, this kind of cork can only last for half an hour, and then it is ground into wood chips. The development of the first steam engine failed, and we had to wait for the metalworking technology in the territory to be further improved and the gap at the piston to be reduced.

After the failure of the steam engine, Cheng Pan set the direction of research in another aspect. As a modern person, there is no stranger to electricity, the principle of the motor is mainly to cut the magnetic induction line, the left and right hand rule. Historically, the emergence of the motor later than the steam engine was mainly stuck in the principle of electricity, and Cheng Pan, who was tempered by the college entrance examination system, was not ashamed to teach the achievements of the electromagnetic giants to the people of this time and space, of course, the excuse was still ordered by the sky. Many artisan students in the territory did not doubt it, after all, thunder was a sacred existence in the cognition of the ancients. However, with the passage of time and the progress of science and technology, after Cheng Pan left this plane, the origin of electromagnetism became an academic pit in this plane. The initial application of electricity was unsuccessful.

The principle of the motor is indeed very simple, and the technical requirements are not high, but the process is difficult. The first pit is the search for magnets, there are very few natural magnets in nature, and electrical engineering requires magnets to form a magnetic field. Modern magnets are industrially manufactured. Cheng Pan didn't pay attention to this, and began to be very entangled. Later, a doctor provided a method for making permanent magnets, which was taken from the practice of guiding fish in the fifteenth volume of the first volume of the "General Essentials of the Wujing" compiled by Zeng Gongliang during the reign of Renzong of the Northern Song Dynasty. It is to burn the iron sheet red and arrange it in the north-south direction, then quench it, and magnetize it with the earth's magnetic field. For Cheng Pan, the earth's magnetic field was weak, so Cheng Pan first made a motor with natural magnets, and then made a magnetic coil with silver wire, after which a strong magnetic field was generated in the magnetic coil, and then the red-hot iron rod was stretched into the magnetic coil and quenched. The effect of magnetism on an artificial magnetic field is surprisingly good. In this way, Cheng Pan accumulated a large number of magnets. Then it was convenient, Cheng Pan led people to cut off a small river to make a dam, and used water conservancy to drive a water wheel to cut magnetic induction wires, and electricity was transmitted from the copper wires wrapped in lacquered cloth. A new energy source was born.

But the embarrassing moment came, the electricity was made but it couldn't be used. The first transmission of electricity is made by hydropower, and the electricity can not be transmitted too far, although the manufacture of alternating current, but the voltage is too low, the transmission loss is too large, Cheng Pan is not untried transformer, the transformer principle is very simple, that is, the magnetic coil with a small number of turns corresponds to the magnetic coil with a large number of turns. According to the high school physics book cottage out of the product after use, the voltage is up, but the current drop is too big, the motor is weak. Then there was a smell of burning, the enameled silver wire burned, and then there was a burst of electric sparks, and the counterfeit was scrapped. Electricity can't be transmitted far, so Cheng Pan feels that it is better to use water conservancy directly. It costs so much silver wire and copper wire can only be transmitted for dozens of meters, which is too undrawn, anyway, there are more open spaces by the river.

In the end, the motor unit was retained, and the chemical laboratory accepted it. Changed to a direct current motor to do electrolytic real yàn, the output of refined copper increased dramatically. Chlorine and pure hydrogen are also generated. However, the electrolysis reactor did not continue to expand, and as a raw material for chlorine, the salt could not keep up with the consumption. Originally, Cheng Pan's transportation of a large amount of salt from the sea was completely sufficient for the consumption in the territory, but it could not support the consumption of industrial production.

Fortunately, it is not only the chemical group that needs electricity, but also electric soldering. Numerous motor units were built around him. Cheng Pan thought about it, but he still couldn't give up the temptation of the steam engine. Cheng Pan set up a team to solder steam engines and process cork stoppers in large quantities, using them as a consumable. The new steam engine can be easily replaced with a wooden piston. So in this era when materials science was so backward, the steam engine came to the next generation.

In this way, Cheng Pan staggered forward in the process of dynamic revolution.
