Leonardo da Vinci once said: The eyes, known as the windows of the soul, are the key to the mind. Only through them can the mind examine the infinite works of nature in the most magnificent and extensive way.

The "windows" on the outer wall of the Sforza Castle are just the right size for pigeons to nest. Perhaps Leonardo da Vinci recorded detailed notes and sketches of bird flight through observing these pigeons, as well as analysis of how birds maintain balance, move, grasp direction, dive and rise in flight. These words are written in mirror characters.

When dreaming, you can fly as high and as far as you want, and compared with the complicated traffic rules on the ground, there are no restrictions in the sky. Sirius and Harry can ride flying motorcycles and broomsticks as fast and as far as they want.

Adopting a hippogriff like Buckbeak requires the ability to cloak, and driving a flying car also requires invisibility spray and other restrictions.

Pomona had seen the Star-shaped Square in front of the Arc de Triomphe in Paris in the 20th century. There were no lines there at all. As long as it was not during rush hour, traffic was smooth and there was no congestion. Only pedestrians and Citroëns were seen "whizzing" forward, obeying some invisible traffic rules.

If you see that all cars except your own are going against the flow on a highway, do you have to correct everyone?

In addition to not giving way to each other, there is another situation where all cars drive on the right. This road is large enough for two-way traffic, but a horse-drawn carriage suddenly changes lanes from its own column because it is in a hurry and there are no cars on the opposite side.

He rushed all the way and kept meeting cars on the opposite side. Horses are not like machines. They will also be frightened. In panic, they will do things that violate the principles of mechanics, which will eventually lead to completely unpredictable results.

Simon proposed that the purpose of laying tracks underground is to let everyone move forward in order and not have any off-track actions. Of course, this is an ideal state.

Underground tunnels are narrower and darker than those on the ground. Once an accident occurs, it will be a disaster. With the current level of human technology, this concept cannot be achieved, and the most critical factor is the relationship between individual basic rights and public interests.

Sirius was chased by the police while riding a flying motorcycle on the ground because he was speeding. Urban traffic has speed limits, and no one cares in the wilderness. If there is a traffic accident, it is also his alone.

Traffic jams due to traffic accidents are called reflex injuries, and all people stuck on the road due to accidents are participants.

One person's enjoyment of public interests cannot interfere with other people's enjoyment of public interests, just like one person's freedom cannot be at the expense of others' freedom.

In a "rule of law society" where it is not about who has a more powerful father, everyone must abide by the law, and everyone is equal before the law.

When Voldemort was eradicated, Sirius had no use value, and Dumbledore did not defend him as he did in the past when he was in school. If Harry was an ordinary student, Dumbledore would not defend him either. At best, he would treat Hagrid and Scamander the same way and arrange other ways out for them after they were expelled.

Both Grindelwald and Dumbledore like to talk about "greater interests".

Dumbledore needs Harry to stay in school, and he cannot be expelled from the Ministry of Magic.

Simon did not participate in the "negotiation" with the temporary residents in the dungeon because of his injury, although it was only a superficial wound.

Most dark wizards can be tempted with benefits. Unlike Harry, they are extremely loyal to Dumbledore and have never doubted the old fool.

Dante's poem forced a woman to leave the crests of two families on her coffin.

Even after death, men will not let go of their wives who are still alive, assuming that only living people can have "ownership" of things. Once a person dies, ownership disappears, and goods and assets change hands. Women are not included in this. A man who hates the thought that his wife may marry someone else after his death can include such a clause in his will that his wife only enjoys a life interest in the estate (life income), and if she remarries, her rights to the estate will be eliminated. This clause is more common in the 19th century.

The widow lived in a monastery, isolated from the world, wearing white clothes and shaving her hair, just like what Dante asked Beatrice to do in his poem.

For a widow who could not go out, what did the right of passage and traffic problems have to do with her?

She could only look out the window and watch the hustle and bustle of the world. If she had any crooked thoughts of remarrying, someone would curse her: Poor thing, she must still be eager to wear it.

Harry was forced to have no way to live, as if he had to sacrifice himself because he was the last Horcrux.

Normal people have a desire to survive, even dark wizards are not as extreme as Dumbledore, and Voldemort is also afraid of death, so he asked Narcissa to check whether Harry was dead. Dumbledore also counted his own death, and he used his life to demonstrate to Harry what "sacrifice" is.

As a bell rang from far to near, the pigeons in the window holes all flew away, and soon the eagle landed in a window hole in front of Georgiana.

It flew for an afternoon and was obviously a little tired, breathing with its mouth open.

Georgiana conjured a water ball and let it float in front of the eagle. The eagle drank the water ball without any fear.

Before leaving, Bonaparte once said that she was nothing and should not agree to any request made by the Italians.

"You are just like me, and you are just a plaything in the end." She said with a wry smile.

"I don't think so."

Georgiana looked back and saw Bougainville climbing up the narrow brick stairs.

"I heard the rumor," said Georgiana.

"What rumors?" Bougainville asked.

She kept looking into his eyes.

Napoleon said that in order for others to understand you, you must first speak to their eyes.

What should she say now?

"The Italian you met today, what did he say to you?" Bougainville asked.

In fact, before the appearance of the Zeppelin, the Wright brothers had designed an aircraft that was completely controlled and relied on its own power to remain in the air without landing. However, it could not carry as many bombs as the Zeppelin.

At that time, Britain had no air defense system, so Henry Potter called on wizards to participate in World War I.

"I heard that he came to Milan this time to apply for a patent." Georgiana said with a smile, "He invented a marine propeller."

"Like a paddle wheel?" Bougainville asked.

"No, it's underwater," said Georgiana.

It already has the prototype of a propeller, but it lacks a power system.

she thought to herself.

When she saw Simon in military uniform, she should have thought that not everyone was like Fresnel and refused to use his inventions in war.

"Another thing is that Leonardo da Vinci envisioned abandoning the walled city and making it more open, which would be conducive to the development of the suburbs and the smooth flow of traffic in the city center." She continued, "Tear down the city wall, and there will be no need to pass through it." There are several existing gates for entry and exit.”

"You said you took Queen Catherine as a role model, what do you mean?" Bougainville asked.

"What?" she asked confused.

He sighed and then laughed, "I think many people misunderstood you."

"I know a person. Many people misunderstood him, but after the truth came out..."

"What happened when the truth came out?" Bougainville asked.

"Nothing." Georgiana looked at the eagle, which looked very majestic under the sunset.

"Tell me what happened outside, my guardian." She said calmly. "I chose the truth instead of beautiful lies, so God gave me the dragon's heartstrings."

Bougainville thought for a moment.

"Do you know where the lookout is?" Bougainville said.

"On top of the mast, of course."

"Have you climbed the mast? Lookout."

She frowned at Bougainville.

"How long can you stay at the masthead?" Bougainville continued.

"What?" She was extremely confused.

“There was a girl who lived on top of a redwood tree for two years just to stop other people from clearing that forest,” Bougainville said with a laugh.

She was too surprised to speak.

"Who do you think is more stubborn, you or her?" Bougainville asked.

"Am I stubborn?" she asked in disbelief.

"Don't you think you are stubborn?" he asked.

"What do you think about my stubbornness?" she asked unconvinced.

He smiled wider.

"Come on, it's dinner time."

She took out the pocket watch given by Mulla.

"Isn't it still early?"

"After dinner, go to bed early. There will be a vigil tonight." Bougainville said.

"I want to see the girl who lives in the cedar tree." Georgiana walked down the steep stairs with Bougainville's support.

The artificial stairs were so awkward to climb down that she didn't think she could live in a tree for two years.

Unexpectedly, Bougainville burst into laughter, as if he had heard something very funny. The laughter echoed in the fortress, causing the pigeons elsewhere to fly away.
