Since ancient times, the reason why various dynasties and generations have stipulated that officials are not allowed to do business is because officials have great rights, and if they get involved in business, ordinary businessmen will not be able to live their lives, which will cause very serious unfair competition, and ordinary businessmen will have no way to compete with officials no matter what.

However, even if there are such regulations, it will not solve the problem of unfair competition, after all, it is not possible to do it on the surface, it can be done secretly, officials themselves cannot run business, but they can operate behind the scenes, and people who can control themselves can run business, and they can also earn a lot of money.

In addition, there are many businessmen who will take refuge in one or more high-ranking officials, and will pay tribute to these high-ranking officials with a part of the money they earn, so as to obtain the help of these high-ranking officials, and then obtain unfair competition opportunities.

That is to say, since ancient times, the competition in business has almost never been fair, there is a word called the red-top businessman, which is the collusion between officials and businessmen, any small businessman, if he wants to become the largest businessman, without the backing of the big official, it is absolutely impossible, only with the support of the big official, can he grow step by step into a big businessman on the rich side.

In short, no matter what era it is, fairness is absolutely non-existent, it can never exist, and the people and small businessmen at the bottom can only pick up the leftovers of others, and it is too difficult to counterattack.

Even the battery invented by Ang Lee has to be handed over to the aristocratic class to operate, not to the common people, after all, ordinary people are not capable of running this business, only the powerful have such ability, in this way, the elite class will fall into a virtuous circle, and the poor people can only fall into a vicious circle, which is a problem that cannot be solved in any era.

If hundreds of ordinary people are united to build a workshop, it is inevitable to nominate one person to manage, and this person who is elected by everyone will soon become a new nobleman, that is, the elite class, and the rest of the people will be poor people.

Although this fact is cruel, but the reality is that many times, in order to create wealth with maximum efficiency, it is necessary to let a few people manage, and the majority of people work hard, such efficiency is the highest, and the consequence of this is that a few people can become nobles, and the majority can only be the lowest poor, can only make themselves food and clothing.

Therefore, instead of creating a new aristocracy, it is better to let the existing aristocracy run this relatively monopolistic industry, so that the number of nobles will be less, and the exploitation of the common people will naturally be less.

It is precisely because all the big officials know this kind of thing, so naturally no one will object to the officials doing business in private, and it is useless to know it, the big officials all hand over their business to people who can control it, even if they are found, it cannot be proved that it is the big official, unless the person falls, and a large amount of property will be found when the house is raided.

"The flashlight is very practical, and the battery is a consumable, so there is no need to worry about future sales."

"Yes, yes, it is estimated that the number of batteries ordered by the imperial court alone will not be a small amount!"

"Yes! Chang'an City is full of lights at night, but there are no lights in the corners, there are no lights in the nearby countryside, the demand for flashlights is very strong, go out with a flashlight, it is much more practical than a torch. ”

"What, how many of you are interested?"

"Don't dare, don't dare, such a good business, where can it be our turn."

"There's nothing that can't be turned, Li Shilang said, to choose the three with the highest bid, it is the three to share, as long as it is the top three, there will be a chance."

"What three to share, look at it! Sooner or later, they will become a family, anyway, I don't dare to count on it, so as not to get into trouble. ”

After the ministers left the court, they did not rush back, but gathered together to chat.

Li Ang went to the R&D center, where there are more assembled flashlights, and he wants to put these in the most prosperous places in Chang'an City, and build a large shed in these places that can completely block the light, so that the flashlights can perform in it to their heart's content, day and night.

"Li Shilang, you have to choose ten locations, do you want so many!"

"There are at least five or six people who need to be responsible for maintaining order and taking care of things at every location, which is too much!"

"There are too many people in the capital, and there are not many locations, how can more people know about this flashlight? It's not much. ”

Several subordinates said.

Li Ang divided ten points to show the newly developed flashlight, it is absolutely reasonable, it is to let more people in the capital understand the new technology of flashlight, although it is just a small daily necessities, but the use is very large, it is necessary to promote.

The flow of people in the east and west cities is relatively large, with two points set up in each, and there are also two points on Suzaku Avenue, and the remaining four are scattered in the rest of the capital with more people.

The area of the ten-point shading tent is not small, and it is not a problem to accommodate three or five hundred people inside, which can maximize the understanding of more people about the flashlight, so that more people can participate in the competition, and in order to later stage, such products can enter the market and increase the sales of batteries and flashlights.

In order to ensure the safety of each point, Li An mobilized 150 people, 15 people at each point, who were responsible for setting up the blackout tent, and then performed the light of flashlights and ordinary torches inside the tent, so that the people who came to visit could see how much advantage this flashlight had been.

The construction of the shading tent is very simple, that is, first use wood to build a shelf, and then, cover the outside with a shading cloth, and the so-called shading cloth is actually a mixture of black and white threads woven cloth, which can effectively block the passage of all light, reflect and absorb all light.

From the outside, the shading cloth is white, both faces are white, but the internal color is black, the white reflective effect is the best, and the black light absorption and shading effect is the best, the two colors are mixed together to make the shading cloth, which can block the strong light to pass through to the greatest extent, so as to play the role of shading, so, for the highest efficiency of shading, the shading cloth chooses the way of mixing black lines and white lines for weaving.

Ten shading points were quickly completed, and each point was already equipped with flashlights and torches, lanterns and other items for lighting, and was ready to be compared, so that the common people could see how much advantage flashlights had.

Since ancient times, the common people of China are the most fond of watching the lively, where there is the lively to see, where to see the lively, so, after the shading shed is set up, there have been a lot of people gathered around, there are merchants, farmers, there are also people in the housekeeper of the aristocracy, and there are many people from other races.

However, the shed can only accommodate three or five hundred people at most, so you have to queue up to see the excitement, and go in one by one to see the excitement.

This kind of scene is a bit chaotic, so Ang Lee will never go in person, just leave it all to his subordinates to complete, while Ang Lee himself stays in the R&D center and continues to develop the good things that Datang needs.

If you want to study a variety of use items, the most important thing is that materials and machinery are the same, without the right materials, everything is impossible, only give you wood and soil, what can you research, only by studying a variety of properties of materials, in order to promote the further growth of the research career, and in addition to materials, machinery is also extremely important, if there is no help from machines, even if you are given iron, copper, alloy and other items, you will not be able to make such powerful things, or the efficiency is very low, As a result, labor costs have been pushed up, which is not conducive to promoting it to thousands of households.

Therefore, machinery and materials are very important, of course, chemical and biological engineering are also very important, but they have little to do with the study of various items, and they have a significant role in other aspects, and chemical technology can be used to make weapons, such as black powder, which is caused by the chemical reaction of three substances, and if you want to make more powerful explosives in the future, you also need a lot of knowledge in chemistry.

Biology can be used to study drugs to control the spread of the epidemic when necessary, and it can also treat many major diseases that plague people, so that people can live better and more at ease.

After all, the production of batteries, the manufacture of black powder, etc., all belong to the field of chemistry, if you do not engage in chemical engineering, many things cannot be made, such as batteries cannot be made, and incidentally it will also affect the invention of radio and telephone, so chemistry still has to be done.

Through so many years of hard work, as well as the joint cooperation of hundreds of thousands of R&D talents, Ang Li at this time has developed a large number of materials, much more than the previous materials of Datang, whether it is new building materials, or mechanical and metal materials, many times more than before, and the successful research and development of some materials has an important role in promoting the next research.

For example, without the successful development of special metals, the barrel of the gun cannot be made thinner, and the gun that is too heavy will inevitably greatly limit its mobility and sustained combat ability.

There are also many parts of machinery that are easy to wear, if ordinary pure metal is used, it is easy to be worn off, and if advanced alloys are used, as well as new materials that have been quenched at high temperatures, the wear resistance will be greatly improved, so that these parts are not so easy to be worn out, so that they can be used for a longer time.

A variety of new materials are constantly being researched, and the research and development of new materials is crucial for subsequent research, such as firearms, which have very high requirements for weight, and if they are very bulky, it is difficult to use them alone.

Among all materials, only the strength and toughness of metal can meet the strong friction, so the barrel must be made of metal, and metal materials are relatively bulky, if the thickness of the barrel is very high, the weight of the gun will exceed the maximum standard that a single person can load, so that the gun can not be used normally, it is better to make a gun cost-effective.

The advent of new materials that are stronger and tougher can solve this problem well, so that the guns can be made thinner, so as to facilitate the carrying of soldiers, so as to reflect the portability and lethality that guns should have.

Ang Lee's minimum requirement for a rifle is that it cannot exceed twenty catties, and a gun that exceeds this weight, coupled with the weight of a large number of bullets, will cause too much burden on the soldiers, and less than ten catties is a relatively high requirement, and it is also the direction of Ang Lee's efforts.

For the pistol, Li An's requirement is within five catties, more than this weight, it is estimated that one hand can not be lifted, so, how to use it normally, so, it must be light, the pistol of later generations is only about two catties, and the rifle is only five or six catties to more than ten catties, unless it is a machine gun that shoots continuously, it will be slightly heavier to meet the requirements of continuous shooting.

The gun that Li Ang aimed at first was a rifle with very advanced performance, and as for the backward arquebuses and flintlock guns, they went around directly, otherwise, the guys made were not as good as bows and arrows, and it would be a waste of resources.

The research and development of most of the components has achieved good results, and the only thing that dissatisfied Ang Lee is the research on the barrel and firing pin.

If the material of the barrel is unqualified, the weight of the barrel will be too large, thereby increasing the weight of the overall gun, making the gun lose portability, and the demand for the material is relatively high, and the firing pin with bad material will wear out after a few uses, so that it can not hit the next bullet normally, resulting in the unusability of the entire gun, or the need to replace the firing pin frequently, resulting in a lot of pressure on logistics.

However, both of these studies are underway, and it is believed that a breakthrough will be made soon, and once these two developments are completed, powerful and reliable guns can be born.

This technology was quietly developed by Li An, and he did not tell the emperor and ministers, and their main energy was attracted by the Wanli Transsonic Project, so they didn't pay attention to the research and development of these small parts of the barrel, even if the people from the imperial court came to inspect and saw the barrel and firing pin, they couldn't understand what it was for, maybe they thought these were parts on the machine?

Li An didn't want to deliberately hide anything, it's just that the current Tang Dynasty is already so powerful that the surrounding forces are frightened, and it seems that there is really no need to develop more advanced weapons, that is to say, there is no such weapon as a gun, for the power of the Tang Empire, there is no fundamental change, the strongest is still the strongest, so Li An doesn't want to ask for credit for the time being, besides, the cost of guns is much more expensive than swords, and every bullet consumes the metal materials that the Tang Dynasty urgently needs.
