"Your Majesty, I am very impressed by your general understanding, and I believe that after cooperation and communication between us, we will be able to put aside our old suspicions, restore mutual trust, and face the threat from the Holy Roman Empire together." William Howe praised without hesitation.

"So do I, Lord William." Although Henry I had already made up his mind to settle William in the next war, under the critical external situation of the Kingdom of France, Henry I had to pinch his nose and admit William's request for an alliance: "I am willing to be an alliance with you against our common enemy." I just don't know what conditions you have to put forward to tide over the difficulties for me in France? ”

"Actually, I don't ask for much, and there are even conditions that will help you, for example, I will give you a loan of tens of thousands of pounds of silver, with an interest rate of two cents a year, and a repayment amount of ten years, and these funds will be used to give away to His Majesty Ferdinand I, to withdraw him from this war, and to let him help you and the Kingdom of France." William made the first condition that he provide a loan to the Kingdom of France to urge Spain and Ferdinand I to withdraw from the war, apparently for the sake of Henry I, but this was not the case.

These 100,000 pounds of silver were only nominally lent to Henry I, in fact, William did give Ferdinand I a reward for sending troops to help William, and Henry I, who did not get any gold coins, needed to repay William a huge amount of money totaling 300,000 in principal and interest during the ten years, and with this heavy debt on Henry I, he didn't want to recover his strength quietly.

"The interest rate you gave me is fair, I'm willing to accept it, but I don't know what the additional requirements are?" Although Henry I felt that something was wrong with him, thinking that William and Ferdinand I's son-in-law might be conspiring with each other to deceive him, the Spanish army and the Normandy soldiers surrounding Paris and the Cité made Henry I have to accept William's terms.

"During the repayment period, the customs duties of the Kingdom of France and other countries will be supervised by the customs and taxation agencies established by Normandy, and the Normans will be responsible for collecting the customs duties to pay the principal and interest of the loan due to us, and we will not withdraw until you have repaid the principal and interest." William held up a finger and said.

"I agree to an alliance with Normandy, and I trust you to persuade Ferdinand I to return to the realm, but how do you prevent others from coveting the crown of France?" Henry I did not understand the importance of customs duties, because most of the taxes of the French crown came from his direct domains, as well as the annuities paid by his vassals, which were currently not very large.

"The Kingdom of England in the northwest of France and the Kingdom of Denmark Canute II, and the Duchy of Flanders Baldwin I, just leave the defense against these two men's threats to me." William nodded slightly, and came up with his own solution.

"Well, I see, William. That is, not knowing how you will face the threat of the Holy Roman Empire? It is the most powerful Catholic country on the European continent. Henry I's eyes twinkled, as if trying to extract his information and solution from William.

"I have my own opinion, and I can guarantee that the Holy Roman Empire and Emperor Henry III will not have time to look at France. However, this will require you to sign the alliance treaty that I have drawn up. William patted his chest and shouted.

"Very well, I am willing to accept your terms, and I can conclude an alliance now." Henry I nodded yes and said.

William handed over a twelve-page pact with detailed terms and instructions, which had already been drawn up, and the material of the rhinoceros shaft for its shaft added a lot of opulence to the pact.

The terms of these covenants were made by William with the aim of weakening the economic power of the Kingdom of France and making it a dumping ground for Normandy products, in order to weaken the fighting ability of the other side.

After Henry I confirmed that it was correct, the covenant was signed by William and Henry I in triplicate, one for William, one for Henry I, and the last for Archbishop Reims and his church for safekeeping, and eventually the two sides would help each other and support each other in accordance with the binding provisions of the covenant, and jointly fight against the princes of the Holy Roman Empire and other countries.

"Now you can speak, Your Excellency Duke William." Henry I looked at William and asked with some anxiety.

"Well, in addition to defending myself in Normandy against the threat of the Duchy of Flanders and the Kingdom of England, I have my own means in transferring the Holy Roman Emperor Henry III." When William said this, his tone paused, and he looked at Henry I's slightly expectant eyes before continuing:

"That was to shift their aim, so that Emperor Henry III would treat the march on Rome as their primary goal.

Since the founding of the East Francian Kingdom and the Saxony dynasty by Henry the Birdcatcher, Duke of Saxony, his three descendants, Otto the Great, Otto II and Otto III, were crowned emperors of the Romans, the Holy Roman Emperors.

For 200 years, marching into the great city of Rome and crowning him Emperor of the Holy Roman Empire by His Majesty the Pope has become something that all monarchs who want to make a difference want to do.

It just so happened that His Majesty Henry III had not been crowned emperor in Rome since his accession to the throne, and his legitimacy had been questioned, so that simply sending someone to blow the wind in his ears could arouse his desire to march into Rome.

In this way, France's greatest crisis can be resolved. ”

"However, the strength in the hands of His Majesty the Pope is not as strong as that of Henry III, and His Majesty the Pope and the Italian region may not be able to last long in the hands of Henry III." Henry I worried.

"Of course, this requires the support of His Majesty the Pope from my Normandy and your France, as well as Spain under Ferdinand I.

With the support of our three parties, His Majesty the Pope, relying on the direct guards in his hands and the support of the Italian princes, can at least withstand the attack of Henry III.

Moreover, His Majesty the Pope is a close friend of mine, and he will be willing to help us in any way he can, which will be of great benefit to us.

If at this time we can contact some kingdoms that are willing to fight for His Majesty the Pope, and form an alliance against the Holy Roman Empire, it will not be difficult to defeat the Holy Roman Empire at that time. William elaborated.

"This plan is very good, at least it can make the war burn in the unexpected area of the Kingdom of France." Henry I nodded in agreement.

In fact, William didn't have any good intentions, except for the Duchy of Flanders, which William had to attack, the Holy Roman Empire or something should be left to France and other kingdoms, so they couldn't take care of William.

William, on the other hand, was only responsible for selling all kinds of weapons and equipment, and not sending troops to shed blood for others, and the blood of the Normans would only be shed for the Normans.
