In February 632 AD, after nearly 10 months of arduous campaigning, the angel army led by Su Dingfang finally pacified the Nanzhao Kingdom, which was high in mountains and long roads, complex terrain, large trees and deep forests, full of miasma, poisonous insects, difficult roads, and many ethnic groups.

Goguryeo was destroyed, Baekje was destroyed, Xue Yantuo Khanate was destroyed, Nanzhao was destroyed, and the whole country of the Tang Dynasty celebrated, rejoiced, and was extremely excited.

Fusang saw that the original Goguryeo allies were destroyed by the Tang Dynasty one by one, and he was afraid that the Tang Dynasty would destroy it next. Emperor Tianzhi (the eldest brother of the prince) hurriedly sent an envoy to the Tang Dynasty to show goodwill, expressing his willingness to surrender to the Tang Dynasty and send an envoy to learn from the Tang Dynasty. Emperor Fuso Tenchi (the eldest brother of the emperor) was willing to give 60 million taels of silver as war reparations for the Battle of Baijiangkou of the Tang Dynasty.

Huang Wan, a minister who used to spend time in Fuso for business, said that Fuso has many high-quality silver mines, the largest of which is Iwami Ginzan, which is located in Daejeon, Root County, Fuso Island, and that Fuso accounted for one-third of the world's total silver production during the Sui and Tang dynasties, most of which came from Iwami Ginzan. Huang Wan suggested that the Tang Dynasty increase the amount of war reparations, otherwise it would send troops to occupy Iwami Silver Mountain.

Tang Dynasty. The army wanted to garrison Fuso, and occupy their treasure Iwami Silver Mountain, Fuso was terrified for a while, and finally after heated discussions, it could only agree to increase the amount of war reparations to 20,000 taels of silver, that is, 200 million taels of silver, to be paid in 10 years. Because Fusang is a small island country with poor land, lack of resources, frequent earthquakes, and narrow terrain, the Tang Dynasty actually didn't look down on occupying it, and finally agreed to Fusang's conditions.

Fusang sent a large number of envoys to the Tang Dynasty to study culture, Buddhism, systems, and architecture, with a focus on learning weapons manufacturing technology, iron ship manufacturing technology, agricultural technology, and other industrial technologies.

However, Xia Xue is absolutely secret about guns and other weapons manufacturing, shipbuilding, steel smelting, glass, cement, steam engines, internal combustion engines, generators, telegraph machines, oil extraction and refining, high-energy bombing and other technologies, in order to prevent leakage, the core knowledge of these technologies is only mastered by herself, and the production process of many weapons and machinery, from the very beginning to the final finalization, to the quality acceptance, is mostly divided into dozens or even hundreds of processes. Each worker is only responsible for one of the processes, so that the process design is not only conducive to improving technical proficiency, improving production efficiency, but also conducive to technical confidentiality.

She knows the shortcomings and bureaucratic corruption of the state-owned company, so all her more advanced technology manufacturing and so on are produced in her own specially established angel company, the angel company is a head office, the chairman and president are themselves, the name of the legal person: Changsun Xue, the nature of the company is a private joint-stock limited company, he holds 80% of the shares of the head office, and the other 20% of the shares can be raised through the issuance of shares, but because Xia Xue controls 80% of the company's shares, In the company, he will always be the absolute boss and the absolute authority. Many wealthy businessmen know that angel companies are producing magical products that others will not produce, and the profits are super high, so the shares of angel companies are not worried about issuing them at all.

Xia Xue divided the angel company into several subsidiaries, and selected a few managers who have passed layers of assessment, loyalty and reliability, a very strong sense of responsibility, serious and down-to-earth, and outstanding ability to assist themselves in managing each branch.

Xia Xue personally formulated the corresponding management system of the factory, workshop, enterprise and company, and required the company's employees to strictly abide by it, otherwise, they would be deducted bonuses, wages, or even fired, and never hired. Because the treatment of the angel company is so good, there are countless people who want to work in the angel company, so the people who are hired cherish the work of the angel company very much, and they are basically very serious and practical, and there are few violations of the company's rules and regulations.

And the angel company hires personnel very strictly, and will never hire people who are not qualified, no matter what kind of official you are, the rich second generation, etc., it is useless, intercede, go through the back door, and write notes. Gifts, bribery, etc., don't work in angel companies. The angel company only recognizes Xia Xue's orders, and Xia Xue's orders are to strictly follow the company's various systems, including the recruitment system.

Xia Xue turned the company into her own private company, also for the sake of future generations and the secret in her heart. She knows that after a few years, the emperor's hereditary monarchy system will basically not work, and the whole world will slowly become a democratic election system, if it becomes a democratic election system, then her descendants will definitely not be able to be monarchs and emperors, if there is no private company of her own, the experience of later generations tells Xia Xue that the descendants of those emperors who have been deprived of their rights are not doing well, let alone have any influence. Xia Xue needs her children and grandchildren to maintain a strong influence all the time, even if she is not an emperor, she still has a strong influence, and this is only through her own private enterprises and family businesses, which will be protected and welcomed by all countries in the future. Xia Xue wants to turn her angel company into a huge multinational company in the future, rich and powerful. Governance is built on the basis of the economy, and with strong financial resources, it will influence the political, military, industrial, and economic circles, and thus affect the whole world forever. Xia Xue needs her angel company to always have super influence, because she has secrets in her heart.

Xia Xue hopes to build her angel company into a super global company with a rich country and superhuman influence in the future. Because she knows that a company has more stable independence and stronger control than a country, and the chairman and president of a company have higher authority and stability than the president of a democratic society in the future, the president of the future country will be impeached and removed from office at every turn, and even arrested and imprisoned, and the president of the future country will be vetoed and overturned by the people, the parliament or the next president at every turn, and it is difficult to ensure its long-term stability and sustainability. Therefore, many presidents only formulate short-term plans and short-term beneficial things to improve their political performance to consolidate their position and power. And the huge secret in Xia Xue's heart is that it takes many people to persevere, even thousands, of perseverance and unremitting efforts for hundreds of years, or even thousands of years, to be realized. And this secret plan is incomprehensible to many ordinary people, and it will cause social panic and social contradictions, so it is also a secret plan that should not be made public. This kind of secret plan needs to consume a lot of financial, material, and human resources, and it may not have any benefits in hundreds of years, or even hundreds of years, and it may always be throwing money, burning money, and investing, such a secret plan, put in any country, especially any future democratic country, no country can stick to it, not only is it not financially out, but the most important thing is the vigorous opposition and obstruction of ordinary people, bureaucrats and parliaments, after all, most people in the world are only concerned about their immediate interests. It will not consider the fate of the earth and the fate of mankind, which will be unattainable in hundreds or thousands of years. Therefore, this kind of long-term and arduous grand plan with no short-term benefits can only be accomplished by a private company with super deep pockets, super great influence, higher authority, stronger independence, greater stability, better confidentiality, stronger sustainability, greater coherence and resilience. This is why Xia Xue has been desperately developing and expanding her angel company.

The weapons army huo military manufacturing company is not sold to the outside world, including angel rifles, angel cannons, angel machine guns, angel warships, hand shells, mines, napalm. Advanced military products such as ammunition and high-energy explosive bags are only provided to the escort teams of the Angel Army's special forces, naval fleets, marines, angel companies, and factories, and are basically non-profit secret production. Xia Xue will use the money earned from other projects to subsidize the manufacturing and R&D of the military huo company every year, anyway, Xia Xue's other companies make a lot of money, which is enough to support this special military huo company. Technicians, when there is no production task, continue to engage in research and development, and constantly improve the performance and power of weapons such as angel guns. Production workers, when they are not producing weapons and ammunition, will be transferred to other machine parts production workshops to help, that is, there are no production tasks for the time being, and wages and salaries are also paid a lot, so the technicians and workers working in Angel Army HUO Company are very relieved.

Telescopes, telegraphs, and the range is appropriately relaxed, and can be used for Datang. Military dui limited sale.

The production of angel crossbows, Tang knives, and light plate armor can be used against the Tang Dynasty. The military is open for sale, but the military wants to buy it at the sales price, and this is profitable.

Due to the large demand for cement production, it is not a strategic product that affects the overall situation, Xia Xue in addition to the cement production company's key core technology secrets, the production of cement machinery and equipment can be sold. Many cement manufacturers buy machinery and equipment produced by Angel Company, and use local limestone and other resources to build cement plants to process and produce cement. Angel company also provides after-sales service on how to use these equipment and matters that need attention, so all over the country areas rich in limestone resources have come to buy angel company's cement production equipment, angel company in cement production has become a production of cement, while selling production equipment, making a lot of money.

The production of glass products is still strictly confidential, because Xia Xue knows that ordinary glass production technology is not difficult, and if the secret is leaked, then there will be no current huge profits. In the future, others have also developed ordinary glass production technology, so they will manufacture glass with more advanced performance and more complex technology, such as shatter-proof glass, soundproof glass, vacuum glass, temperature control glass, self-cleaning glass, high-purity quartz glass, bulletproof glass, smart glass, etc., in short, Xia Xue wants to ensure that her company will always lead other companies in a certain field. In order to ensure that the technology has been leading, Xia Xue will spend 40% of the company's profits on new technology research and development every year.

Ordinary steel smelting, internal combustion engines, electric motors, steam engines, steel cargo ships, generators, textile machines, tractors, electric lights, etc., Xia Xue only sells manufactured machinery and equipment and products, and the profits are super high. These machines and equipment have earned a lot of money to Xia Xue Angel Company.

Petroleum exploitation, petroleum refining, rubber processing, special steel, alloy material manufacturing, special machine parts manufacturing and other technologies are also strictly confidential, and their products are generally not sold to the outside world, only used for their own internal machinery manufacturing and equipment applications. Only processed diesel, lubricating oil, etc. can be sold to companies and individuals who have purchased Angel Company's internal combustion engines and generators, and anyway, due to technical secrecy, they don't know how this thing is made.

For Angel Pharmaceutical Company, Xia Xue is also strictly confidential, Xia Xue knows the huge profits of drugs, if the patent secret is not protected, then it will be like ordinary glass technology will become worthless after leakage. Angel currently develops the main drugs: penicillin, quinine, artemisinin, Yunnan Baiyao, etc.

Penicillin is the first drug developed by Xia Xue, because penicillin is an important antibiotic with high efficiency, low toxicity and wide clinical application, which can treat pneumonia, tuberculosis, meningitis, endocarditis, diphtheria, anthrax and other diseases. Following penicillin, Xia Xue gradually developed antibiotics such as streptomycin, chloramphenicol, oxytetracycline, tetracycline, etc., which greatly enhanced the ability of the people and soldiers of the Tang Dynasty to treat infectious diseases and saved tens of millions of lives.

The reason why penicillin can not only kill germs but also do not damage human cells is that penicillin contains penicillin can hinder the synthesis of the cell wall of pathogens, resulting in the lysis and death of germs, while human and animal cells have no cell wall.

In fact, Xia Xue found that many tailors in Chang'an City in the Tang Dynasty would put green hairs on their fingers cut by scissors to help the wound heal.

After a long period of research experiments, Xia Xue finally extracted penicillin crystals by freeze-drying. She found a mold on a melon that could be used to extract penicillin in large quantities and prepared a corresponding culture from corn flour. Driven by these research results, Angel Pharmaceuticals was slowly able to mass-produce penicillin.

Quinine, also known as cinchona cream, is the main alkaloid in the bark of the cinchona tree and its contemporaries, and it is an antimalarial drug. The cinchona tree is native to South America, but Xia Xue has it from the plant seeds she brought with her in the future, and she has successfully cultivated it in Southeast Asian islands such as Nanyue, Yunnan, Taiwan, and Indonesia.

Artemisinin, also used for the treatment of malaria, is mainly used for symptom control of vivax malaria and falciparum malaria. The source of artemisinin is mainly directly extracted from Artemisia annua; Or extract artemisinic acid with higher content in Artemisia annua, and then semi-synthesize it. However, except for the eastern part of Chongqing, Fujian, Guangxi, and Hainan, the artemisinin content in Artemisia annua produced in most parts of the world is very low and has no use value.

Quinine and artemisinin have a very great effect on miasma malaria, and the reason why Su Dingfang led the angel army to conquer the miasma of Nanzhao was mainly to protect the health of the angel army soldiers by relying on these two secret medicines.

Yunnan Baiyao has a good effect on bruises, wounds and bleeding. It is made of precious medicinal materials, and has the effects of removing blood stasis and stopping bleeding, invigorating blood and relieving pain, detoxification and swelling. On the battlefield of the rain of swords and arrows, it is the Don. The life-saving elixir for the soldiers to come back to life. Many soldiers were injured, as long as they could still move, they did not wear bandages, did not sit on stretchers, only took Yunnan Baiyao, ate a little, applied a little, and could go into battle to fight, which was called "the holy medicine of wounds" by the soldiers.

These relatively advanced drugs, due to the current low production, are basically only available to the Angel Army and the elite Tang. After all, Angel Pharmaceutical Company is an enterprise, and it needs profits to continue to engage in research and development, and it needs profits to survive and develop for a long time. "In business", Xia Xue has always been a "brother who settles accounts" in business, and does not engage in loss-making business.

Angel Chemical's best-selling daily chemical products, such as soap, soap, laundry detergent, perfume, toothpaste, toothbrush, anti-corrosion coating, plastic products, rubber soles, toilet paper, etc., are very popular. What Xia Xue didn't expect was that the best-selling of these daily chemical products turned out to be synthetic rubber soles. Later, after researching the market, it was found that most of the soles of the ancient people were hand-sewn mille-feuille soles, some soles were made of wood, some soles were made of animal skin, and some were made of twine and hemp. Angel company production of synthetic rubber sole, strong and wear-resistant, soft and comfortable, excellent elasticity, light and convenient, with acid and alkali resistance, waterproof and rainproof, can withstand many bending, stretching, compression without destruction, can adapt to a variety of sports, therefore, synthetic rubber sole once launched, it is very popular in the market, sold at home and abroad, although the price of synthetic rubber sole Xia Xue is not cheap, but the product has always been in short supply. Toilet paper sales are also very good, this is mainly due to the ancient women are basically monthly holidays, unlike women in the future era only once a year, so, after disinfection, soft texture of toilet paper is very popular with women in this era, of course, families with better family economic conditions, both men and women, young and old, like to use the soft and clean toilet paper produced by Angel Chemical Company, so toilet paper sales have been very hot. The production technology of these chemical products and daily chemical products is also kept strictly confidential by Xia Xue and will never be leaked.

The seawater salt drying plant Xia Xue has been changed into a processing plant specializing in the production of fine salt and refined salt, no longer selling coarse salt, and taking the high-end route, which can increase the sales price and profit.

To produce fine salt in the sun, Xia Xue has transformed the original salt drying plant, and adopted the process of new brine, thin drying, short-term crystallization, and regular activity of brine and salt ballast, so that fine salt with uniform particles can be dried.

Xia Xue uses the brine made of dissolved coarse salt as raw material, removes the soluble impurities by chemical methods, clarifies, and then evaporates, crystallizes, dehydrates, dries and sieves to produce refined salt, which does not contain impurities.

Of course, although these technologies are not complicated, Xia Xue is still strictly secret, just like producing glass.

Intellectual property awareness, patent awareness, Xia Xue from later generations of course attaches great importance to it.

Therefore, the envoys from Fusang wanted to learn artillery manufacturing technology, but in the end they were disappointed. However, due to the Tang knife, bright armor and other technologies Xia Xue told the eldest grandson Wuji, the eldest grandson Wuji later handed over this to the Tang Dynasty Royal Weapons Workshop to build, the royal is the state, of course, the shortcomings of state-owned enterprises can not be overcome, corruption, bureaucracy, so that Fusang sent the Tang envoy finally opened the gap through bribery, learned the technology of making Tang knives, and finally Fusang made the "Japanese samurai sword" after imitation and learning. The envoys of Tibet and the envoys of Fusang sent to the Tang Dynasty stole the manufacturing technology of the Tang knife from the Tang Dynasty Royal Weapons Workshop through bribery, and made the "Tibetan knife" after imitation and learning.

With regard to agricultural technology, sweet potatoes, potatoes, corn, high-yielding wheat, high-yield rice, and other new varieties of crops, Fusang and other countries that are currently friendly to Xia Xue are still open-minded.

However, these new varieties of grain are not given away for free, they all need to be purchased at a high price, Xia Xue, who has a strong sense of patent property rights and a strong sense of business, knows that only mutually beneficial and profitable business relations can be maintained and developed for a longer time, and simple charitable acts or giving acts of kindness cannot be sustained. Just like those philanthropists who only want to be famous, or like Zhu Di, the Yongle Emperor of the Ming Dynasty, who sent Zheng He to the West just to show off, their actions are unsustainable.
