Charlemagne's ambition is very great, especially after the victory of the expansion campaign again and again, the ambition has become more and more inflated, and he is almost about to regard himself as a god, but when he encounters failure, it will also hit his expansion heart to a large extent.

For example, in a battle with Rahman, the army under the command of Charlemagne was defeated, and the losses were quite large, and there were strong enemies in the rest of the directions, so Charlemagne's arrogance was suddenly much weaker, and he didn't want his empire to make enemies on all sides, so that even if his strength was strong, it would be difficult to defeat him with two fists and four feet, so after he saw Rahman's strong strength, he had already given birth to the meaning of peace talks.

In Charlemagne's territory, the threat came from three main directions: the Saxons in the northeast, the opposition in the southeast, and the kingdom of Rahman in the southwest.

Among them, Charlemagne's most headache is the Saxons in the northeast, in order to conquer the Saxons, Charlemagne has launched eighteen active attacks, the war lasted for more than 20 years, almost every year, it was a cruel protracted war, because of this protracted war, the Saxons lost a quarter of the population, Charlemagne's soldiers and horses also suffered heavy losses.

As for why Charlemagne fought desperately to attack the Raksen people in the northeast, in addition to the difference in religious beliefs, there is also the need for imperial expansion, Charlemagne is worried that the Saxons will become strong one day, so he must first attack and completely conquer them, so as to extinguish the possibility of the rise of the Saxons.

Just like Emperor Yang of Sui in China, after seeing the strength of the Goryeo Kingdom in the northeast, he launched many military campaigns against Goryeo, but he never won the victory.

There is also a saying in China since ancient times, called the side of the couch is not allowed to let others sleep, the empire ruled by Charlemagne, all the common people must believe in Christianity, and the Saxons have their own beliefs, and there is no intention to change their beliefs, which makes Charlemagne very dissatisfied, let a country with a different belief from his own empire, stay by his side and develop slowly, it is really a dangerous thing.

The beliefs of the Rahman kingdom were also different from those of Charlemagne's empire, which was the main reason for Charlemagne's southward attack.

However, in comparison, the northern Saxons are more threatening, after all, the northern Saxons have a relatively large border area with Charlemagne's empire, and it is a relationship between a strip of water, while the situation of the Rahman Kingdom is different, the Rahman Kingdom is on a half-road, and the area bordering Charlemagne's empire in the northeast is not large, and there are mountains and rivers blocking it, which is a very good dividing line.

Therefore, Charlemagne must conquer the Saxons in the northeast, even if he suffers extremely heavy losses, and he is willing to negotiate peace with the Rahman kingdom in the southwest, so as not to fall into the dilemma of being caught between two sides.

Charlemagne sent his subordinates to Cordoba to negotiate peace, Li Ang naturally knew about it, and before arriving in Córdoba, Li Ang had already planted eyeliner here, so everything that happened in Córdoba, Li Ang was very clear, and he also knew that Charlemagne was a drunkard who did not mean to drink, and the biggest purpose of the peace negotiation team was to understand the Tang Dynasty.

However, the thing that surprised Ang Lee was that Charlemagne's subordinates had been waiting for so long, why hadn't they got in touch with their own people yet, was it just as simple as looking, recently, Ang Lee had given a lot of weapons to Rahman, how could these guys not react?

"Li Shilang, Charlie's people are here, and it seems that they still can't hold it back."

The subordinate spoke.

Li An smiled slightly: "Since you are here, of course you want to meet them, please let them in!" ”

After speaking, he began to brew the language, preparing to meet the people of Charlemagne.

After a period of greetings, Charlemagne's subordinates made their intentions clear and expressed the desire of Charlemagne's empire to get along with the Tang Dynasty amicably.

Since Charlie is willing to be friendly with the Tang Dynasty, of course Ang Lee will not reject people thousands of miles away, and the more countries that are friendly to the Tang Dynasty, the better, and the more the more they can reflect the charm of the Tang Empire.

"It's good to say, it's easy to say, Datang is willing to establish friendly relations with all countries in the world, and also hopes that all countries in the world can get along amicably, and return the people of the world to a stable life."

Li An said kindly.

This is Li An's ideal, but also in line with the interests of the Tang Empire, if the maritime Silk Road through the countries, all of them are at war, then, the Tang Dynasty opened up a commercial road will suffer heavy losses, only along the way all countries can live in peace, everyone around the Tang Empire, in order to achieve the greatest commercial interests.

"Li Shilang is so right, we came here this time to negotiate with Rahman, as long as the border between the two countries is determined, the probability of war in the future will be greatly reduced."

Charlemagne's subordinates spoke.

Li An said with certainty: "Well, that's really good, I hope the two of you can reach an agreement as soon as possible, and there will never be a war again." ”

"We are absolutely sincere in peace talks, but Rahman defeated us last time, and now Datang has supported them with a lot of weapons, so I'm afraid they won't be so willing to talk peace!"

Charlemagne's subordinates spoke.

Li An said: "Don't worry! Definitely not, the weapons we support are all cold weapons such as bows and crossbows, and the power is not as great as imagined, and it will not change the force comparison between the two of you, in addition, although you lost last time, Rahman did not win well, and their losses are not small! You have all kinds of problems in the country, and it is the same with Rahman, the internal opposition, and the threat from the south are always there, so you really shouldn't attack each other, it won't do you any good. ”

"What Li Shilang said is, but can we buy some Datang weapons? Just like Rahman. ”

Charlemagne's subordinates asked.

Li An smiled and said, "Okay, I'll sell you ten sets, which are exactly the same as the weapons that Rahman obtained." ”

For these cold weapons that have been completely eliminated, Li An really doesn't care at all, even if they are imitated by these effects, it doesn't matter much, after leaving for so long, the R&D center of Chang'an City must have made a lot of good things, and the technology must have accumulated a lot, so that after going back, Li An can invent more advanced weapons, and it is not a problem to get a rifle or anything, and once the weapon of the gun is interviewed, the sword and the bow and crossbow will become useless things, even the most backward arquebus, Its range and power also surpassed that of a crossbow, not to mention the flintlock pistol, or even a rifle.

Li An has been industrializing in the Tang Dynasty for a while, and now that he has accumulated so many years of technology, it should not be much of a problem to get some rifles, and after returning to Chang'an City, Lee Ang will get rifles, first equipping the forbidden army in the capital, and then popularizing it step by step.

However, after the invention of the rifle, it is estimated that many people will object, after all, the power of this thing is too great, especially suitable for assassination activities, since ancient times, assassin murder is done with swords and bows, the power of these two weapons is very limited, the success rate of assassination is not high, and it is difficult to retreat to a safe place, and assassination is often simply suicide.

Once the rifle was invented, the Assassin was able to take a surprise attack from a distant location, and if he succeeded, he quickly fled the scene and continued to fire his guns at the pursuing guards to escape to safety.

Of course, the power and range of the cannon are greater, but the size of the cannon is too big, and it is very difficult to sneak attack quietly, and the number of artillery pieces that each army has is numerous, if there is one less, it will be easy to be found, and the size of the gun is relatively small, and it is estimated that it is difficult to find when there is one less in the army, and when the assassin is in use, it can also be easily carried, so as to kill people unconsciously.

That is to say, once the gun falls into the hands of people with ulterior motives, it is very likely to become a tool to assassinate the enemy, and even, as the emperor of a country, will feel that it is not safe enough to go out, so as long as Li An develops the gun, there will definitely be a certain controversy in the imperial court on the matter of equipment, but because the gun is of great help to improve the combat effectiveness of the army, so, even if it encounters huge opposition, the gun can still equip the army in the end, but for the management of this weapon, It is estimated that it will be very strict, especially at the beginning, I am afraid that only the most elite soldiers and horses can be equipped with such powerful weapons, and the common soldiers and horses can still only use cold weapons, so as to minimize military costs.

Wars are fought with money and food, which has been the case since ancient times, and weapons that consume too much money are generally difficult to gain large-scale popularity, or even be eliminated directly, unless this army is really rich and flowing, otherwise, it really can't support it.

For example, the Mo knife of the Tang Dynasty has become an excellent equipment in the army because of its great power, but by the time of the Great Song Dynasty, the Mo knife has disappeared, some people say that it is because of the war, which has led to the loss of the technology of the Mo knife, and some people say that it is too resource-consuming to build the Mo knife, the cost is too high, and the rest of the spears and spears are much cheaper, so in order to make the army popularize weapons as soon as possible, it is natural to choose low-cost spear weapons, and the high-cost Mo knife has become a burden on the army. It's only natural to be eliminated.

Whether it is the cost of manufacturing, or the cost of consumption and maintenance, the gun is far more than the cold weapon, after all, a big knife can be used for a long time, just sharpen it when fighting, and the gun is a precision weapon, the cost of manufacturing is high, it is much more difficult than building a big knife, and when in use, it is necessary to constantly consume ammunition, these ammunition are costs, in addition, the life of the gun is certainly not as good as the cold weapon such as the big knife, after the bullet is too much, the barrel will be scrapped, or it will not be accurate, And the barrel is the most expensive part of the entire firearm.

Therefore, even if Li An makes such advanced weapons, he can only equip the most elite troops, and moreover, he must act in a unified manner, and such elite troops are not allowed to act alone, so as not to fall into the hands of the enemy with such advanced weapons.

Many large countries in later generations, while supporting small countries, will not support their most sophisticated weapons to small countries, because the big countries are worried that the weapons they help will be captured by the enemies of the small countries and then sent to the enemies of the big countries, so that the technology of the big countries will be leaked, and the losses will be quite heavy.

Of course, because the technical strength of all countries at this stage is relatively weak, so, even if Datang's weapons are obtained by other countries, they do not have the ability to imitate, not to mention the technology and its complex ironclad car, even if it looks quite simple, these barbarian countries are not capable of imitation, even if it can cause the appearance of Datang Modao, but the technical and tactical indicators are definitely unqualified, which is beyond doubt.

Since the technology will not be leaked, then, the main problem is to focus on the safety of the big guys, in case an enemy seizes a gun and uses it to assassinate a high-ranking official of Datang, for example, it will bring great losses to Datang, this risk is obvious, and it must be paid special attention to.

It is precisely because of this factor that Li Ang did not develop the gun for a long time, and took the first step to get the cannon out.

Of course, there is another important reason, is that Ang Lee really doesn't like the arquebus, and wants to do it in one step and directly invent a rifle that can have strong power, which requires technical accumulation, of course, it has to take its time.

Charlemagne's subordinates, after getting Li An's promise, seemed very happy, although Li An only agreed to sell him ten sets of weapons, but as long as Datang agreed, his task was completed, and he could return to the north with these ten sets of weapons, and he could explain to Charlemagne.

After Charlemagne's subordinates left, Li An began to think about the preparations for returning to Datang, after all, the complete task has almost been completed, there is really nothing to be nostalgic about, and it is time to go back.

Although Rahman sincerely retained, Li Ang still had to leave as soon as possible, and after returning to Datang, Li Ang still had a lot to do, and he couldn't stay outside forever and waste time.

Of course, before leaving, Ang Lee will leave behind his right-hand man, after all, whether it is to coordinate the relations between Rahman and his neighbors, let them live in peace, or build the port of Gibraltar, there needs to be a reliable person in charge, otherwise, Ang Lee will not be at ease.

Before leaving, Charlemagne's people came to Li Ang again and wanted to discuss more cooperation projects, but Li Ang was about to return to Datang, and there was not so much leisure time to chat with them, so he introduced his right-hand men to Rahman, and in the future, if they had anything, they could go directly to their subordinates.
