In this meeting between Tong Guò and Zhao Min, Cheng Pan revealed his intention to go to the sea to the local high-level of the Yuan Dynasty. For Cheng Pan, a local unstable factor, the high-level leaders of Henan Jiangbei Province have a helpless mentality towards Cheng Pan's scourge, and it takes too much effort to eradicate it, and the damage is too great, which affects their careers. Ignoring him, he was afraid that he would continue to expand and reach Cheng Dù, who had to be exterminated. It can be said that Cheng Pan's territory was like a pustule in the Yuan Dynasty, squeezing it, it would be inflamed, not squeezed, it would grow bigger and bigger. When Cheng Pan was willing to go to sea to exhibit, the officials of the Yuan Dynasty were brightly eyed, and Cheng Pan expressed his unwillingness to fight with the imperial court and wanted to go to sea to exhibit, which was like exile Cheng Pan's possible rebellious energy overseas, and this solution was too perfect for the magistrates of Henan Jiangbei Province. There is no need to fight Cheng Pan's strong force to eliminate this danger. Everyone thinks it's a great deal. According to the report of the spies, a big ship was being built in Cheng Pan's territory, which confirmed the credibility of Cheng Pan's words. Of course, some people raised concerns that Cheng Pan might build these big ships to sneak attack Nanjing, and this idea was quickly overturned, and Cheng Pan's forces could cross the river lightly at Xiaohuangzhou, and build big ships to attack Nanjing. However, no one thought that the power of the overseas exhibition would threaten the 6 places, which shows that people in this era do not pay attention to the ocean.

Now the high-ranking officials of the province are actively operating on Cheng Pan's appointment as the county magistrate of Rugao County, and there are more investigations into Cheng Pan's territory, and at the same time, some voices that originally advocated suppression of Cheng Pan have also stopped, and they are waiting for the next development of the matter. After all, the Yuan Dynasty is now old. Among the Han scholars in the south of the Yangtze River, the sharp-eyed people have been close to the Yuan Dynasty, and there have been no major disasters in recent years, but the human market has become more and more prosperous. The imperial court lavishly rewarded the temple with land. Land is becoming more and more concentrated. There are all indications that it only takes one disaster year for the displacement to rise up. In the coming Chen Sheng Wu vast and unscrupulous mud legs to muddy the world's water, some talents will show their talents, and these virtuous talents who have read the scriptures can choose the male master, assist Ming Jun, and leave the name Lingyan Pavilion. Originally, Cheng Pan played the role of stirring up in the minds of these Jiangnan scholars. Cheng Pan is very in line with the image of this character in their minds, first rude, teaching people to write typos (simplified Chinese), and shamelessly promoting it on a large scale in mud legs. Failure to adopt virtuous and cruel treatment of scholars (land reform). At the same time, it had strong military force, and the first encirclement and suppression of the Yuan Dynasty was eliminated in World War I. According to Jiangnan Shizi's assumption, after Cheng Pan eliminated the Yuan Dynasty army for the first time, his ambitions swelled and he began to rebel further, and was finally killed by the Yuan Dynasty as the head bird, and at the same time severely damaged the Yuan Empire. It's a pity that Cheng Pan is a very timid person, with the ambition to do big things, but he is extremely unconfident in his luck, and he will never have a showdown with his opponent without a hand to crush the opponent's cards, not to mention that there are other people who take cards on the game.

Cheng Pan had to admit that it was the Mongols who had the most powerful force in this era, and the one with the greatest potential and wisdom was the Jiangnan Shi clan at this time. In order to break the Mongol military oppression and the cultural monopoly of the landlord class. Cheng Pan can only lurk, vigorously promote simplified Chinese characters and Hanyu Pinyin in his own territory, simplify the medium of knowledge dissemination, and make it easier for the broader people at the bottom to learn knowledge. Later generations said that traditional Chinese characters are like noble ladies, and simplified Chinese characters and Chinese pinyin are like domestic helpers. It is true that compared with traditional Chinese characters that are like an art painting, compared to simplified characters, they are like precious seafood and coarse tea and light rice, but in the vast number of Chinese in the Enlightenment era, only those upper class people who are detached from basic labor have time to learn traditional Chinese characters like seafood, and the vast number of grassroots working people are like a high threshold under heavy work. They are unable to record simple technological progress in traditional Chinese characters, and those who master traditional Chinese characters at the top are unwilling to record seemingly simple but basic technological changes in the muddy rice fields of hard workshops. Because no one in the profession of managing the people is competent except them, and no one can read the exquisite and complicated official documents. Everything is inferior, but reading is high.

Cheng Pan was unwilling to be bound by the literati of the landlord class, so the simplified Chinese characters recorded the basic crafts of craftsmen one by one for all craftsmen to study, and each technology was preemptively registered by craftsmen under their own names. In this part of China, writing began to serve as a carrier of basic craft knowledge on a large scale, and the spark of the Industrial Revolution is shining in the experience of craftsmen in writing. At this time, Cheng Pan's most important power was the 5,000 students who graduated from junior high school, and these students either majored in basic physics or chemistry. They joined the factory, the real room, one technology, one material formula after another was innovated by these 5,000 brains. Cheng Pan, as a traverser, now feels that he is finally not fighting alone, in the system he created, an advanced force of the Yue era is vigorously unfolding, as long as it is given enough time to develop, the power it creates will surely overturn the whole world.

Now Cheng Pan is coming to the chemistry room on Xiaohuangzhou, where 1,000 chemistry junior high school graduates are working, exploring the various formulas that have emerged in industry. At this time, He Feng, the leader of the chemistry group, said to Cheng Pan: "Teacher, we have some arguments about industrial products."

Originally, with the increase of iron and steel production and the mining of iron ore in large quantities, the original local coking method had long been abandoned, and the iron and steel workers spent a lot of effort to make a special furnace for dry distillation of coal to reduce the waste of coal coking. However, in the process of coking coal, there is a product, with the current technology, each ton of coking coal will always produce about ten kilograms of oily substance, this oily substance is very corrosive, can not be directly touched by hand, that is, leather gloves are corroded a lot. This substance cannot be lit because it produces a large amount of toxic smoke when burned. The chemistry group became interested in this substance and began to analyze the chemical composition of this substance, and now it has a high proportion of carbon relative to hydrogen, and carbon ions account for more than half of the number of hydrogen molecules. At first, the chemistry team thought that it was mixed with pulverized coal particles, but later it was fractionated by a fractionation tower to separate a special concentration of clear oil. However, the carbon content of the transparent substances separated by the chemical group Tongguò combustion test is still very high. Some people believe that this substance is still mixed with carbon element, but the carbon element in this substance is clear, just like steel stone. However, some people believe that it is not because of the mixing of large amounts of carbon elements to produce this high-carbon oil. But the chemical bonds don't make sense.

Cheng Pan followed them to do a day's practice, with the chemical forgetfulness of junior high school, Cheng Pan had to discuss with them, suddenly Cheng Pan saw a person bored on the paper to draw a series of carbon, one of which is connected to the tail, Cheng Pan reacted at once, and the chemical formula of benzene, the six-carbon ring, was determined. Subsequently, several basic substances to be fractionated in coal tar were established. I thought it was over. But more than twenty days later, good news came.

On that day, Cheng Pan was observing the construction progress of the sea vessels by the riverside. At this time, a man from the chemistry group arrived on horseback. With a smell of gunpowder smoke on his body, he came to Cheng Pan and said to Cheng Pan with a look of excitement in his eyes: "Sir, we have synthesized a new type of gunpowder, which is very powerful."

Cheng Pan completely underestimated the curiosity of people in this era to explore this discipline after they came into contact with the knowledge of chemistry, and as soon as the benzene family was discovered, the people in the chemistry group began to try the most dangerous nitrification practice. Well, they did nitrate acidification at different concentrations, made a series of mixtures such as dinitrotoluene and dinitrophenol, and smashed a bunch of ceramic glazed utensils specially made for the chemical real room, slightly injured three people, moderately burned one person, in this era without antibiotics, through the simple disinfection of guò normal saline and pure alcohol, this person lay down for 1 month and escaped from the ghost gate. If they get concentrated nitric acid with a purity of up to 95%, they will also carry out a third nitrification reaction, so that they can make trinitrotoluene and trinitrophenol, which actually have a more familiar term for modern people, TNT and picric acid. Even the product of only two nitrifications is a fierce explosive. Unfortunately, the production of nitric acid is insufficient. At this stage, it is not possible to produce large quantities, but now coal tar, which used to be annoying, is strategically stored.

At the same time, after seeing that his group of chemists had a tendency to turn into scientific maniacs, Cheng Pan strictly stipulated the rules of safety tests and ordered a large number of expensive alloy armor from the forging department.
