In 1344 AD, that is, the fourth year of Yuanzheng to the fourth year, Cheng Pan, who ignored Goubuli, arranged his own farming career with peace of mind.

As the ships descending down the river were busy, a large amount of materials were transported to the Rudong branch base. The 20,000 people in Rugao County began to put labor into production under the organization of Cheng Pan. These new labor forces will create wealth under Cheng Pan's system. Currently, the population controlled by Cheng Pan is breaking through to the level of one million, while the population of the entire Yuan Dynasty was about 60 million at this time. The ancient statistics were somewhat incomplete, and the migrant population could not be calculated. You can also increase by 10 million as appropriate. The population in Anhui is about 400.

Between ten thousand and five million, Cheng Pan occupied about one-tenth of Anhui's land, but absorbed one-quarter of Anhui's population. The Han self-cultivated farmers who were chased by the Mongolian and Yuan nobles did not find a abandoned land to survive as before. Instead, they entered Cheng Pan's territory as if they were pouring into a safe island. Relying on the overhaul of the water conservancy territory in recent years, they could still be self-sufficient. However, due to the advanced production tools, the existing agricultural population has already filled the arable land in the territory. The new population has gradually transformed into an industrial population.

As Cheng Pan spared no effort to improve the literacy rate, people using simplified Chinese characters began to form a huge group on the Jianghuai land, and they had quickly caught up with the entire Chinese gentry group in terms of number of people alone. The speed of learning 400 words in the territory was too terrifying. This way of industrializing the production of junior workers was only possible in the Chinese character cultural circle. Knowing 600 Chinese characters is not illiterate in China, but only knowing 600 English words in the UK is definitely illiterate, and there are at least tens of thousands of common words in the Latin department. After passing Level 6, you will speak 6,000 words, and your English level is not as good as that of the American rural aunt.

The construction of Rugao County was quickly rewarded. With the start of the salt drying field, the first batch of cheap salt was transported back to Xiaohuangzhou. In order to tinker with sulfur and hydrochloric acid, the chemical students in Cheng Pan's territory used sodium carbonate as by-products. When Cheng Pan saw a large amount of soda ash in the chemical warehouse, he became messy in an instant.

As a member who survived the college entrance examination battlefield, Cheng Pan certainly heard of Hou Debang's contribution to Chinese chemistry. However, whether it was the Western monopoly alkali-making method he conquered or the later joint alkali-making method, Cheng Pan roughly swept the chemical equations. Since there were more than a dozen chemical equations, it was not required to take the test, Cheng Pan didn't remember it either. But Cheng Pan knew that both methods required ammonia as raw materials. Cheng Pan now saved even a qualified high-pressure cylinder to make nitric acid, so where did the ammonia come from? When they understood the chemical group, they played the alkali-making process by themselves, Cheng Pan felt his dogma.

Let’s talk about the sulfur production method of hydrochloric acid developed by Wang Ziqiang of the Chemical Group. Yes, his original meaning was to produce sulfur and hydrochloric acid. Sodium carbonate did not expect it to appear. First, let the table salt and concentrated sulfuric acid heat to produce steam and sodium sulfate. The hydrochloric acid in the triac acid and two alkalis can be produced in an industrial manner. However, the by-product of sodium sulfate is too annoying. This thing accumulates more and more, and it is also the by-product of sulfuric acid and nitrate to make nitric acid. Then, sodium sulfate, calcium carbonate and charcoal are placed in the stove to burn, and the product produced is a black mixture of carbon monoxide and sodium carbonate and calcium sulfide unburned charcoal. Sodium ash accounts for 45%. Wang Ziqiang is specifically aimed at sulfurization.

Calcium is used to remove calcium. Calcium sulfide cannot contain water. However, once carbon dioxide is present in the water, it will produce rotten egg-flavored hydrogen sulfide. Wang Ziqiang passed the carbon dioxide-rich exhaust gas in the blast furnace into the water, which is precipitated by calcium sulfide. The hydrogen sulfide comes out, and then the emitted hydrogen sulfide gas is passed into the water and the air is poured into the reaction dish. The oxygen in the air oxidizes hydrogen sulfide in the water, and the pure sulfur precipitates. Wang Ziqiang happily obtained the two products that are scarce in the laboratory, sulfur and hydrogen chloride. At the same time, he asked his apprentice to process the dissolving solution of the black mixture in the second step of the reaction. After heating and saturation and cooling, a large amount of soda ash precipitates and is produced.

Due to the industrial production of soda ash, the three acid and two alkali chemical industry chain has been completely formed. (Caolid soda can be ripe lime and soda ash are generated in water). The foundation of modern industry, in addition to synthesizing ammonia, Cheng Pan has basically completed the rise of technology in the main line of technology. This has cleared the obstacles to the development of later modern industries. The fastest change to the territory after the emergence of soda ash is that soda has become a cheap commodity. In the past, soap was specially supplied to special industries such as nitrogen accumulation, and it was too inefficient to use wood ash to make soap. Soap has become the second type of bulk civilian product outside the territory after cheap textiles. (Dear, pick up soap).

After two months, three sand ships had arrived at Taiwan, and found Keelung Deepwater Port to set up an outpost, and then the three ships simply circled the island. They roughly examined Taiwan and came back. After a report, Cheng Pan learned that Taiwan was vast and sparsely populated. There were no more than ten Han villages in the entire island. The mountainous area belonged to the wild villages. The entire treasure island belonged to the land without a border. And at this time, Taiwan was not included in the Yuan Dynasty. I am not the ancestor who promoted the attitude, now the green attitude is still in the mainland, but the southern Fujianese have no chance to occupy this land. No wonder, the entire mainland of China is now abandoned and who would land on Taiwan Island without any trouble. Even if one or two people set foot on Taiwan alone, without collective strength, they would not be able to survive in this safari.

In the docks of Rugao County, a sailboat that does not belong to this era is being built, that is, a fly-scissor. Cheng Pan is illiterate about sailing. Cheng Pan, who has lived on land since childhood, has the only impression of the ocean that is that it is the origin of seafood.

Thanks to the teachings of online literature over the years, Cheng Pan still remembers the word "Slides" and Cheng Pan found the boat maker and asked him to try to build a new boat. Cheng Pan only put forward a few requirements. First, Cheng Pan drew the look of the fly-shear bow, and then asked the boat to lower the center of gravity to reduce the bow building, and then turned the hull into a thin and long way. After explaining these, Cheng Pan became the manager of the hand. Leave the boat maker looking at each other. The leader said a sentence, and the boat maker began to trial-making models according to Cheng Pan's requirements. At the same time, experimented in the water flow. According to experimental data, this kind of ship can indeed sail quickly. Then the boat maker experimented with the wave resistance of the hull. After a series of experiments, the design drawings were finally determined.

So keels were laid in the big pit of shipbuilding to build ships in full swing. Due to the sufficient steel tools and the power to process wooden boards, the shipbuilding speed was extremely fast.

In early summer of 1344, the ship began to sail on the sea. After a period of running-in with the ship, the sailors excitedly drove the ship to test sailing on the sea. The length-width ratio of the hull was 6 to 1, and the drainage was 500 tons. All the buildings on the ship were reduced. When sailing, the entire ship was as fast as it was against the water surface, and the speed could reach 19 kilometers per hour. In this era, any pirate ship could be thrown away.
