William and Ferdinand I met happily, and the two of them traveled arm in arm, inspecting his Spanish army under the leadership of Ferdinand I.

Compared to William's army, the Spanish army was still a medieval aristocratic levy army, each under the command of its own nobles, carrying different noble banners and wearing different armor, burqas, and shields.

The coat of arms drawn on it is also different, some are based on animals, such as lions, horses, fish, eagles, crows, etc., some are based on fantasy creatures, such as griffins, dragons, etc., as well as buildings, such as castles, towers, tents, and some others such as plants, patterns, crosses, etc.

William doesn't understand any of these coats of arms, with the memories of his previous life, William doesn't pay too much attention to this complicated coat of arms, and he doesn't have much time to pay attention to it, even his own coat of arms William only retains the red background and gold double lion flag, and the other coats of arms have long been thrown by William There I don't know.

However, Ferdinand I, who was beside William, studied this very well, and he knew his own coat of arms very well, and the flag represented the earl or baron noble, who this nobleman belonged to, and what it had to do with other nobles, he knew it all clearly.

No way, because Ferdinand I's army was made up of these nobles, from counts to knights, each with its own coat of arms, and if Ferdinand I couldn't tell them, he couldn't command them on the battlefield.

William, who walked side by side with Ferdinand I, listened to his knowledge of heraldry, William only felt that he was admired, he did not expect that a king could be in charge of this science, and the studious William immediately asked Ferdinand I for advice.

With a common topic, Weng and his son-in-law talked happily with each other, and when they talked about their happiness, they laughed loudly from time to time.

"Ferdinand, your Castillan knights are really elite, each of them looks like a dragon, and the mounts they sit on are also very strong." William looked at Ferdinand I and complimented.

"That's natural, we Castilian people have been fighting with the Moors of the Iberian Peninsula all year round, almost a small fight for a few days, a big fight for half a year, there is not a day without a war, we Castilian people must always report their strength, otherwise we would have been defeated by a large number of Moors!" Ferdinand I said proudly.

"I wonder if I can borrow some knights, nobles, and officers from you so that I can strengthen my cavalry troops. You must know that so far, the number of knights under my command has only just exceeded 1,500, but the heavy cavalry has not exceeded 2,000, but there are more medium and light cavalry, but they cannot compare with the power of heavy cavalry.

There are Castile men in my army who work for me, and my Count of Dominia, Rodrigo, is one of them. William was very pleased to see Ferdinand I today, and immediately made a request to him.

"What to borrow or not, I will directly transfer three hundred elite Castile knights to you, and then they will be your vassals, and you can use them to train your heavy cavalry troops." Ferdinand I waved his hand and said in a bold tone.

Three hundred knights are indeed very good, almost equivalent to one-fifth of William's knights, and their combat effectiveness is even more powerful, even more powerful than William's Norman knights.

"Thank you very much, Ferdinand." William waved his hand and thanked him, "I have a business to talk to you about here, and it will be of great benefit to you." ”

"Oh? What is it, I don't lack anything here, it's just lack of money. There is a profitable business to do, and I like it the most. Ferdinand I said with a smile.

"I want to buy war horses and efforts, that is, I will take as many Spanish horses and pagan Moorish slaves as you own.

I can exchange these things for you for gold, weapons, plate armor, paper, cloth, and salt. William suggested.

The Spanish horse is one of the oldest horse breeds in the world, having lived in the Iliban Peninsula since prehistoric times, as can be seen in cave paintings dating back 25,000 years.

The Spanish horse, the Arabian horse and the Bobo horse are the three major horse breeds that have had a profound impact on the world horse breeding industry. Spanish horses are not hot-blooded horses, but they are closer to hot-blooded horses than other horse breeds.

Before the 19th century, the Spanish horse was the first horse breed in Europe, and the horses used in classical equestrianism at the Renaissance Academy were named after the Spanish horse at the Spanish Riding School in Vienna. The most famous white Lipiza horse is a direct descendant of the horse exported from Spain to Slovenian Lipica in the 16th century.

The Spanish horse has had an important influence on all types of horses and is the basis of the pedigree of most horses in the Americas.

The Andalusian horse is a descendant of the Spanish horse and is one of the finest horse breeds in the world.

The Andalusian horse comes from a province called Andalusia in southern Spain, where there is a stallion farm where the horse is bred.

The same kind of horse, in Spain, this kind of horse is called a "pure Spanish stallion"; Outside of Spain, it is known as the "Andalusian horse"; In Portugal, this horse is called the "Lusitanoma", or the horse is the Portuguese version of the Andalusian horse.

However, there is also the view that the Lusitano horse is a completely independent breed, bred by a cross between an Andalusian horse and a native Portuguese mare.

Therefore, William, who was very coveted for this kind of war horse, couldn't wait to put forward a request to buy a Spanish war horse.

"No problem, I can sell you any extra horses and horses, as well as any captured Moorish slaves, as long as you provide enough weapons, plates, and salt.

Your weapons and plate armor, in particular, are so strong that there are hardly any weapons that can cut swords made in Normandy, and no arrows and swords can hurt the knights in plate armor, which my noble knights love the most. Ferdinand I said loudly, "I just don't know what you have to do to buy Moorish captive slaves, it's not good to buy so many infidels, and the Holy See is likely to intervene to stop it." ”

"I bought these slaves to mine the iron ore in the territory, you must know that it takes a lot of iron to make so many armor and weapons, and if you can't mine iron ore yourself, you can't supply the weapons and armor that the whole of Spain needs.

As for whether the Holy See will intervene, you don't have to worry at all, the current Pope, His Majesty Benedict IX, is my close ally, and with him, no one will interfere with my purchase of Moorish pagan slaves. William said confidently.

"Whew, that's good. I didn't expect you to be so capable, William, to be an ally with His Majesty the Pope, it's really not easy. Ferdinand I sighed.
