"You're pretty good." Liu Ruyu smiled and couldn't close her mouth: "I didn't plan to meddle in the business here, the sage specially ordered me to go to sea with the ship just for fun, and I met the person who hugged the qin in a port and stayed, after checking the account book, it was really amazing, do you know how much the spices collected by the people who arranged for the people to collect the baoqin are worth?" ”

"There must be 100,000 to 150,000 Roman gold coins, and the price of these goods to be transported back to Datang will be at least tripled, and the cost of transportation is quite high."

Liu Ruyu looked at Liu Mu in surprise, and then looked at Baoqin.

Baoqin shook her head: "I definitely didn't say the number in the account book. ”

"Needless to say, you can guess how many people you have at hand, how many slaves, and how much output there is in that place. Don't forget, Mogadishu, which I first left behind and then prepared to build a port, will definitely be an important source of frankincense and myrrh for hundreds of years to come, and not one of them. ”

Liu Ruyu was not lightly angered by Liu Mu, and was originally going to surprise Liu Mu, but Liu Mu reacted like this.

Liu Mu showed Liu Ruyu a note, and the numbers on it really shocked Liu Ruyu.

Ordnance, perfume, Chinese medicine.

The predicted annual trading volume of these three items and the terrifying profit are all ten times or dozens of times the profit of frankincense.

"Second sister, you go to the castle to rest for a few days, I'm going to do some serious business."

After Liu Mu walked away for a long time, Liu Ruyu didn't come back to his senses.

I remember that when Liu Mu gave a horizontal knife with a cost of 180 yuan to the military department to settle it for more than 1,600 yuan, in Liu Ruyu's eyes, this was a profit that scared people to death.

At that time, Liu Mu said that 180 Wen was only the cost of materials and labor, as well as the cost of research and development, the cost of machine wear, and the cost of transportation.

Nowadays, the cost of a Roman short sword made by Datang is only one hundred and fifteen yuan, and Liu Mu's offer on this side is not as simple as adding a zero, Liu Mu's offer is three Roman gold coins and six Roman silver coins.

A Roman gold coin is worth about the same amount of money, and if it is exchanged for goods and sent back to Datang, it is a very terrible profit.

Willow also designed a real heavy cavalry ordnance especially for Rome, with a complete set of nineteen Roman gold coins and nine Roman silver coins.

Liu Mu led the people to the training ground.

At the training ground, there were already two thousand Roman warriors lined up.

Liu Mu compared the two armies, the average height of the elite of the Tang army was higher than 1.8 meters according to the algorithm of later generations, and the height of the Roman army was 1.6 meters.

The Romans were the lowest in the Mediterranean, lower than the Franks, lower than the Visigoths, and much lower than the Slavs.

Liu Mu stood beside Li Daozong: "How?" ”

"Don't think about hoplites, unless you use slave soldiers. The Roman aristocracy of Athens would not have dressed their slave soldiers in expensive steel and heavy armor, so the infantry had to be redesigned. It's cavalry, it's good. ”

Liu Mu asked, "How is it a good method?" ”

Li Daozong replied: "Low height means light weight, plus the horses here are heavier than our horses, then you can have a full set of knight heavy armor and horse heavy armor, with a halberd can be stabbed and slashed, and the heavy cavalry here can raid more than seven miles in one breath, and you can raid again after a short rest." ”

Liu Mu nodded: "So, what about the camel cavalry?" ”

"I haven't studied it yet, but for now let's talk about the heavy cavalry, and then the crossbow flying horse. Their riding and archery skills are so poor that it is impossible to build flying horses without two or three years of training now, so they can only rely on crossbows. This one is also troublesome with a crossbow. ”

"What trouble."

Li Daozong smiled bitterly: "Our steel crossbow is too lethal, which makes the nobles of Athens afraid. They believed that the crossbow would be a terrible threat to the nobility if they were a weapon that could be used by slaves, so they were discussing a solution. ”

Liu Mu also smiled helplessly.

In real history, crossbows were used in Europe until around 1100 AD. The crossbows of that period were indeed influenced by the Song crossbows to the west, and then the crossbows of Europe appeared. Originally known as the Barbarian's Bow, the crossbow could pierce through solid metal armor and was known as an evil and ferocious instrument.

It didn't take long for the crossbow to become an official taboo weapon in Europe.

What Yanagi didn't expect was that the Romans were also afraid of crossbows and the powerful lethality they bringed.

Yanagi was eager to tell the Romans how much he loved the crossbow, which was small and lightweight, and a real weapon for killing people and setting fires. The most important thing is that the training is very easy, compared to the two or three years it takes to train a good archer, it only takes three months to train a good crossbowman.

Liu Mu and Li Daozong were talking, and Li Junxian over there had already begun to show the power of the Tang Dynasty's heavy cavalry.

As Li Daozong said before, the Arab war horses are stronger than the original horses of the Tang Dynasty, and based on this, the heavy cavalry must be deployed.

Three hundred horsemen, not much.

However, the 2,000 Roman soldiers were pale in the battle array of 300 cavalry, believing that more than half of their 2,000 men would be killed or wounded in a single charge against such a heavy cavalry.

"It's a pity that there are no god-level heavy cavalry ordnance." Li Daozong said with regret.

Liu Mu disagreed: "As far as their steelmaking skills are concerned, these are enough. Let's go. "Liu Mu didn't plan to stay at the training ground any longer, there is the heavy cavalry skills that Li Junxian led people to train Roman soldiers.

Heavy cavalry in Datang is not only about horsemanship, but also about battle formations, coordination, coordination, and so on.

All the training starts with learning to read the commander's command warrant on the horse, and the hierarchical command orders at each level rely on gestures and body language, not shouting.

Liu Mu left with Li Daozong, and the two came to Liu Mu in one of the basements of the castle.

Torches illuminated the entire basement, and on the basement wall was a circle of wooden figures, each wearing a different armor.

"From the time when the old Roman Empire was strong more than 400 years ago, until now. The armor of Roman generals, elites, and ordinary soldiers. The armor of the surrounding barbarians, the armor of the Persians, the armor of the Arabs that have been obtained recently, and I don't know who it is, as long as it has been collected from the battles in the surrounding area, it is all here. In another room, there are weapons and shields. ”

Li Daozong observed these armors very carefully.

He didn't study too deeply, and Li Daozong believed that since Liu Mu had collected these, he must have arranged for someone to do the research, and there was detailed information for the record.

"Second brother-in-law, the city of Damascus of the Romans is a very important town, which can be said to have the highest steel craftsmanship in Rome, and our steel and iron are not comparable to here before the Sui. If this city were to be taken by the Saracen kingdom of the Arabs, the consequences would be severe, very serious. ”
