Located on the upper reaches of the Danube, Vienna was the capital of the Duchy of Austria.

The scenery here is full of natural and humanistic atmosphere, and the people who live here have long been accustomed to being half with music.

The design of the building includes Roman and Gothic, as well as the emerging Baroque. Sometimes, you can see all three styles in a single building, not because the designer intended to be different, but because it has been renovated over the years.

The local people are accustomed to maintaining a spirit full of innovation, and can always show the artistic cells that are integrated into their bones.

Vienna is a city of music and the home of opera.

Ever since Franz Josef Haydn played his first symphony here, Vienna has been the birthplace of the classical music school.

In the criss-crossing streets, you can see theaters of all sizes everywhere.

Whether it's opera or symphony, music-related activities are a daily hobby for Viennese residents.

The square in the center of the city is a stage for freelance creators to improvise, and flocks of white doves often listen to human music.

Geographically, this area where three mountains meet is a natural fortress.

From hundreds of years ago, when Rudolf I was elected Emperor of the Holy Roman Empire, the Habsburgs have used it as a base.

Successive generations of royal rulers have continued to add their own ideas to the city.

Today, it is recognized as one of the major metropolises in Europe, not inferior to Paris.

But rather than Paris's quest to be at the forefront of world fashion, the Danube-city has tried more to establish itself as a stage for opera and symphonic orchestration.

In order to avoid the majestic Alps, the railway was built in an arc around the east.

The Carlos sisters and Elena took two days by train before finally arriving in Vienna.

The fruits of the Industrial Revolution have improved people's lives to a certain extent, and have also brought many new entertainment facilities.

However, people prefer traditional musical instruments and soprano voices to noisy steam and machinery.

The train slowly drove into Vienna Station with the roar of the new era.

Bella woke up Anna, who had been sleeping beside her.

This simple and cute little boy is able to take eating and sleeping as his main task wherever he goes.

She seems to care more about Vienna's food than in the theater.

Elena was as energetic as ever, and her energetic face never seemed to have anything to do with the word tiredness.

Not long ago, Elena was taking Bella and Anna on a tour of Florence when Cosimo de' Medici received an invitation from Vienna.

Nominally to celebrate the marriage of the youngest daughter of Archduke Maria Theresa of Austria, fourteen-year-old Marie Antoinette, to France, it was in fact to show everyone that the two most powerful empires on the continent had reached an alliance. Like the Habsburgs, they used marriage rather than war to protect their interests in the city-states and the Holy Roman Empire.

Austria and France fought for centuries, fighting for hegemony in Europe on almost every important or unimportant battlefield that can be seen on the map. Until one day, Empress Maria Theresa, then Archduchess of Austria, King of Hungary and King of Bohemia, and King Louis XV of France on the other side, both of them realized the change in the world pattern at the same time.

While the two most politically influential families on the continent, the Habsburgs and the Bourbons, were at loggerheads, the smaller neighboring states rode the wave of the Renaissance and the Industrial Revolution. Prussia in the north was on the move, the Ottoman Empire in the east was eyeing up, and even Britain on the other side of the English Channel began to covet the riches of the interior.

Under the threat of growing power around them, the rulers of these two countries became more and more uneasy, and finally made up their minds one morning to abandon the grievances and hatred of their ancestors, and sent their respective envoys to negotiate for the purpose of peace.

The result of the negotiations was a long-lost peace and a valuable alliance between Austria and France.

The politicians of the two countries clearly understand in their hearts that the so-called covenant is a very fragile piece of thin paper. In order to make the alliance a little more durable—at least for the rest of their lives—these scheming foxes came up with the old and bad idea of cementing the alliance.

That is to establish blood ties.

The Habsburgs were very good at this, and they used it to envelop most of Europe. The royal families of almost every country have their close or distant relatives.

Louis XV was old, and the three princesses under his knees had long since left the court, and he still insisted on marrying an Austrian princess. However, the elderly widower was recognized as an old pervert in Europe, and his private life was so rotten that Empress Theresa and her husband, Emperor of the Holy Roman Empire, Franz I, said nothing that they would push their daughter into the fire. In the end, the hope was pinned on Louis XV's grandson, the future Dauphin. On the Habsburg side, the youngest princess at the time, Marie Antoinette, who was only eleven years old, was chosen.

However, due to a number of reasons, the "deal" was finally agreed upon after three years of bargaining between the two parties.

Taking advantage of this once-in-a-lifetime opportunity, the two countries will, of course, host important figures from Europe's major families to plan for their next political plans.

Considering that his eldest son was still grieving the loss of his lover, Cosimo decided to send his daughter, seventeen-year-old Elena de' Medici, to the biggest wedding in half a century.

"If she can become a wife sooner, will she be able to restrain herself a little?" Cosimo consulted with Ugo.

"Actually, it's not a bad thing that Miss is like this now." The butler replied sincerely.

"Well, at least I hope she'll mature a little bit."

Cosimo sighed helplessly.

As for our Miss Elena, she knows nothing about what her father and the butler were talking about. She had only heard that there was a great banquet in Vienna and accepted the glorious assignment with great joy.

To have the opportunity to go out and play, how could this active girl miss it?

The Carlos sisters were originally Elena's guests, and they didn't have any specific goals on this trip, so they simply accompanied Elena on a trip to the beautiful scenery of Austria.

As for Vienna, I was even more happy to hear that the Carlos family would also go to the banquet.

This mysterious northern family rarely shows up in public, and even Empress Teresa wants to send an invitation, but she doesn't know where to send it.
