Along the way, William and his confidants and friends talked freely about their thoughts, and the time always passed quickly, and it felt that it was not long before he and his army crossed Provence and arrived in Toulouse, an important city in the south-west of France.

"Lord Richard, does Hubert need our help?" William was a little concerned about Barcelona's reluctance to give in, and he wondered if he would personally lead his army south to Barcelona to support Hubert.

"Your Majesty, you don't have to worry about the situation over there, Lord Hubert sent us the latest battle report two days ago - Ramon, Duke of Barcelona, has been captured, and all the princes have surrendered." Duke Richard waved his hand and smiled.

"Then why haven't I heard from me?" William was a little strange, so he asked.

"Your Majesty, you had a great conversation with His Majesty the Pope at that time, where did you care to check the battle report?"

"Oh, I see, in that case, then our army will return to Paris first, and we will wait in Paris for the triumphant return of Master Hubert." William laughed a little embarrassedly, and forced himself to be right.

"Yes, Your Majesty." Duke Richard was unimpressed and bowed to retirement.

When it comes to Barcelona, William naturally thinks of Spain. Castille and León think of their three brothers-in-law - Sancho, Alfonso and Garcia.

Sancho is 26 years old, Alfonso and Garcia are 22 and 20 years old respectively, and his three brothers-in-law have now grown into three sturdy male lions.

Among them, Sancho, who is the eldest brother, is stronger and more belligerent, and is good at military affairs, while Alfonso, who is the second brother, is more good at intrigue and government affairs, but his bravery is not inferior to Sancho, and in the end, Garcia, who is the third, seems a little mediocre, and even a little cowardly in front of the two extremely dazzling brothers.

But even so, the three of them are worthy of being the descendants of William's father-in-law, Ferdinand the Great, at least compared to the other noble children, the three of them are relatively outstanding heirs.

In the future, Sancho, Alfonso and Garcia will write their own chapters on this magnificent stage of history.

William's interest in the three of them naturally had a purpose, as he remembered very well a famous historical event that would take place in the near future - the Cid and the War of the Spanish Succession.

William, who had played Empire 2 in his previous life and watched the old movie Heroes of All Ages, has a very clear memory of this history, about three years later in 1065, a generation of Emperor Ferdinand I unfortunately died, according to his will before his death, he divided the kingdom he owned to his three sons, of which the eldest son Sancho was named Castile, the second son Alfonso was named Leon, and the third son Garcia was named Galicia.

His two daughters also won Zamora and Toro, respectively.

Ferdinand I had high hopes for his sons and daughters, hoping that by dividing the territory, his three sons would be able to maintain their own territory, but soon after his death, his original intention was not realized.

Soon, in order to bring all the territories owned by his father into his command, Sancho first joined forces with Alfonso to target Garcia, the weakest of the forces.

After the two divided Galicia together, the two fought each other again for the throne.

The outcome of the war was obvious, with the help of Cid, coupled with Sancho's own military expertise, he was known as the "Strong" and easily fought Alfonso of León, exiled him to Toledo, and accepted the Kingdom of Leon.

Unfortunately, however, on the way to attack Zamora, Sancho was killed by a man named Beldo. The nobles of Dorfoss were killed by the conspiracy.

Eventually, the exiled Alfonso became the final victor of the war, and as the only surviving son of Ferdinand, he inherited the kingdoms of Castile, León and Galicia, reuniting all the territories held by his father, Ferdinand I, during his lifetime.

The only frustrated was Cid, who had been the commander of Sancho's Guards and the horseman, who had been exiled to Zaragoza for suspecting Alfonso's plots.

Of course, history has changed drastically because of the appearance of William, he married Urraca the eldest daughter of Ferdinand I and had three sons and a daughter, namely the eldest son Richard, the second son Friedrich and the third son Robert, and the eldest daughter Constance, of which the eldest son is already 13 years old, in a few years William intends to let Richard and Matilda Archduchess marry and sit in Italy, the second son Friedrich is also ten years old, the third son Richard is only six years old, and the eldest daughter is the last to be born, only three years old.

Because of his marriage to Ulaka, the eldest princess of Castile, William naturally obtained the inheritance rights of Castile and Leon.

Although this inheritance is still after Garcia in the order of succession, if the three of them fight each other, William will have a chance.

Speaking of which, William intends to emulate the story of his father-in-law, just as Ferdinand seized the throne of León in 1037 in the name of his wife, the eldest princess, Sancha, William intends to do the same.

In fact, William's peep at Castile and Leon was a long time coming, and he remembered these battle-hardened warriors ever since he saw the warriors of Castill.

These Castile knights, who had been fighting to the death against the infidels for many years, were the only ones who could match the Norman knights, and William also coveted a country that could breed such powerful knights.

Especially now that William's expansion plan has reached a certain limit, the only direction of expansion at this time is Spain, the peninsula continent with many small countries and pagan entrenchment.

And from the point of view of cost and benefit, it is indeed more cost-effective to target Spain for expansion than to go toe-to-toe with the Holy Roman Empire and the countries of Eastern Europe.

At this time, the Holy Roman Empire began to emerge from decline and gradually become stronger, the most important symbol of which was the loss of power of the Archbishop of Cologne and the gradual coming of age as Emperor Henry IV of the HRE.

Henry IV, the lion cub, is now about the same age as William's son, he is already thirteen years old, but despite his minority, Henry IV, who lost his parents at a young age, has already learned to be strong and independent, his heart is far more tenacious than other young kings, he has his own goals and ambitions, and he will not be stumped by any obstacles in the way.

Especially with the assistance of Duke Welf of Bavaria and Duke Odoff of Saxony, who were familiar with the interior of the Norman Empire, the HRE Empire would become an extremely difficult opponent compared to waiting a few years for Henry IV to take power.
