A.D. 1344, that is, the fourth year of Yuan Zhengzhi. Cheng Pan, who ignored the dogs, arranged his farming with peace of mind.

In the hustle and bustle of the ships going down the river, a large number of materials were delivered to the Rudong branch base. The 20,000 people in Rugao County are beginning to put their labor into production under the organization of Cheng Pan. These additional labor force will create wealth under Cheng Pan's system. At present, the population mastered by Cheng Pan is breaking through to the level of one million, and the population of the entire Yuan Dynasty at this time is about 6ooo thousand, and the ancient statistics are somewhat incomplete, and the floating population cannot be calculated, and 10 million can be added as appropriate. The population of Anhui is between four million and five million. Cheng Pan occupied about one-tenth of the land in Anhui at this time, but absorbed a quarter of Anhui's population. Instead, it was like pouring into the safety island and entering Cheng Pan's territory. Relying on the overhaul of water conservancy in recent years, the grain in the territory can still be self-sufficient. However, due to the advanced means of production, the existing agricultural population has already enclosed the arable land in the territory. The new population is gradually shifting to an industrial population.

With Cheng Pan's efforts to improve the literacy rate, the use of simplified Chinese began to form a large group in the land of Jianghuai, and the number alone has quickly caught up with the entire Chinese scholar group. The literacy level of learning 4oo characters in three months in the territory is too terrifying, and this way of industrializing the production of primary workers can only be done by the Chinese character cultural circle. Knowing 6oo Chinese characters is not illiterate in China, but knowing only 6oo English words in the UK is ironclad illiterate, and there are at least 10,000 commonly used words in Latin. After level 6, you can speak 6ooo words in English, and your English level is not as good as that of an American country aunt.

The construction of Rugao County soon paid off, and the first batch of cheap salt was shipped back to Xiaohuangzhou as the salt drying plant was put into operation. In order to tinker with sulfur and hydrochloric acid, the chemical students in Cheng Pan's territory used sodium carbonate as a by-product. When Cheng Pan saw a large amount of soda ash in the chemical warehouse, he was instantly messy.

As a member of the college entrance examination battlefield, Cheng Pan has of course heard of Hou Debang's contribution to Chinese chemistry, but whether it is the Western monopoly alkali production method he overcame, or the later joint alkali production method, Cheng Pan has roughly swept the chemical equations, because there are more than a dozen chemical equations, and there is no requirement to take the test, Cheng Pan did not remember. But there is one thing that Cheng Pan knows, both methods require ammonia as raw materials. Cheng Pan can't even make a qualified high-pressure cylinder now, and nitric acid is saved, where does the ammonia come from. After learning about the alkali making process in the chemistry group, Cheng Pan felt his own ideological dogma.

Let's talk about the sulfur hydrochloride production method researched by Wang Ziqiang of the chemistry group, yes, his original meaning was to produce sulfur and hydrochloric acid, and sodium carbonate didn't expect it to come out. First, the table salt and concentrated sulfuric acid are heated to generate hydrochloric acid vapor and sodium sulfate, and the hydrochloric acid in the triacids and two alkalis can be industrially produced. But the by-product sodium sulfate is too annoying, this thing accumulates more and more, and it is also a by-product of sulfuric acid and nitrate to nitric acid. Then put sodium sulfate, calcium carbonate and charcoal in the furnace to burn, the resulting product is carbon monoxide and sodium carbonate and calcium sulfide unburned charcoal these three substances of the black mixture, which soda ash accounts for 45%, Wang Ziqiang is specifically for calcium sulfide this substance, calcium sulfide is not allowed to water but once there is carbon dioxide in the water, it will produce rotten egg smell of hydrogen sulfide, Wang Ziqiang put the carbon dioxide-rich tail gas in the blast furnace into the water that is calcium sulfide precipitate at the bottom, hydrogen sulfide came out, Then the hydrogen sulfide gas is introduced into the water and the air is injected into the reaction dish, and the oxygen in the air oxidizes the hydrogen sulfide in the water, and the pure sulfur is prepaid. Wang Ziqiang happily obtained sulfur and hydrogen chloride, two products that are in short supply. At the same time, let his apprentice treat the dissolved liquid of the black mixture in the second step of the reaction, and after heating and saturation in the cooling process, a large amount of soda ash is precipitated and produced.

Due to the industrial production of soda ash, the three-acid and two-alkali chemical industry chain has been completely formed. (Caustic soda can be hydrated lime and soda ash produced in water). The foundation of modern industry, in addition to synthetic ammonia, Cheng Pan has basically completed the climbing of the main line of technology. This cleared the way for the exhibition of post-modern industry. After the emergence of soda ash, the fastest change to the territory is that soap has become a cheap commodity, and soap was used for special industries such as nitrate, and it is too inefficient to make soap from plant ash. Soap became the second bulk of the household goods outside the export territory after cheap textiles. (Dear, pick up soap).

After two months, the three sand ships have arrived at the treasure island of Taiwan, and found the Keelung deep-water port to set up an outpost, and then the three ships simply circled the island. After a general examination, Taiwan is back. After the report, Cheng Pan learned that Taiwan at this time can be described as vast and sparsely populated. There are only ten Han villages in the entire treasure island. It belongs to the savage village in the mountains. The entire treasure island belongs to the Borderlands. Moreover, at this time, Taiwan was not included in the territory of the Yuan Dynasty. I'm not preaching an attitude, and now the ancestors of the green shade attitude are still in the big 6, but the Hokkien people have no chance to occupy this land. It's no wonder that now the entire China Big 6 is abandoning its own land, who will have nothing to do to go to Taiwan Island to board the 6. Even if one or two people set foot on Taiwan alone, without collective strength, they will not be able to survive in this safari park at all.

And in the dock of Rugao County, a sailboat that does not belong to this era is being built, that is, the clipping boat. For sailing, Cheng Pan is illiterate. Cheng Pan, who has lived in the land of 6 since he was a child, has the only impression of the ocean is that it is the origin of seafood.

Thanks to the teaching of online articles for so many years, Cheng Pan still remembers the word clipper, and Cheng Pan found the boatwrights and asked him to try to build a new boat. Cheng Pan only put forward a few requirements, first Cheng Pan drew the appearance of the bow of the flying clipper, and then asked the center of gravity of the ship to be lowered to reduce the bow building, and then the hull became slender. After explaining this, Cheng Pan will be the shopkeeper. Leaving behind the shipbuilders who looked at each other. In a word, the leader is busy and half dead. The boatwright began to prototype the model according to Cheng Pan's requirements. At the same time, it is real yàn in the flow of water. According to the actual number of yàn, this kind of ship can indeed sail quickly. Then the shipwrights realized the wave resistance of the hull. After a series of practical calculations, the design drawings were finally determined.

So in the big pit of shipbuilding, the keel is being laid, and the ship is in full swing. Due to the abundance of steel tools, as well as two steam engines provided the power to process the planks. Shipbuilding is extremely fast.

In the 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 on the sea. The hull has a length-to-width ratio of six to one and a displacement of 5oo tons. With all the structures on the hull of the ship removed, the whole ship sailed as if it were close to the water, reaching a distance of 19 kilometers per hour. In this day and age, it is possible to throw off any pirate ship.

Cheng Pan named this kind of ship the Haiyan Sailing Boat. Mass construction began. The first Haiyan began to transport people to the Taiwan sub-base in three shifts in 10 days. At present, the construction of two sub-bases for the supply of the main base in Huangzhou has reached the limit. The productivity of the entire territory is fully supplied to the exhibition. The 6th Army, which originally had about 7ooo people, has not expanded. Samples of the rifle were made, but they were not equipped with the conditions. In order to build the army, Cheng Pan postponed the construction of military hardware and only worked training, and the proportion of officers in the army began to increase. And the Yuan Dynasty also relaxed its vigilance against Cheng Pan after Cheng Pan transported people to sea. In between, a long period of peace began.
