The shelves for the telescopes are set up on the rooftop of the upper floor.

It is rarely used in normal times, so the main mirror body is stored in a box.

With Miriam's help, Elena dusted off the dust and finally got the parts out of the box.

Although they hadn't been opened for a long time, Elena was very skilled in assembling them.

"When my grandfather was alive, he was very fond of astrology." "Sometimes when the mood strikes, he can stay on the rooftop all night."

This villa is a little higher than the surrounding buildings, the setting of the roof allows for a relatively wide view, and there are no overly strong lights around, plus it is a sunny day tonight, it is a good choice for stargazing here.

"Alright." Elena said, fixing the mirror body to the shelf, and then began to adjust the distance between the scope and the objective.

When everything was ready, Elena asked Bella to come over and watch.

Through the lens made of glass, the structure of the moon's surface is clearly visible.

"It's incredible." Bella exclaimed.

"Not bad." Elena nodded with satisfaction, "This was made by Mr. Galileo himself, and there are only three in the world. This is the last one he has completed, and it is also the most technically mature. However, in recent years, there has not been much development in technology."

"Well," said Elena after a while, "science is always improving. Mr. Verrocchio had mentioned before that he wanted to make a more advanced instrument so that he could see the stars farther away."

"Really?" Bella said, getting up and giving up her seat to Anna, "If you could see farther, wouldn't there be many new discoveries?"

"Maybe. However, my grandfather once said that no matter how advanced a telescope is, it can only travel through the distance of space, but cannot cross the barrier of time."

"Time obstacle?"

"In other words, humanity cannot see its own future, because the future is always uncertain. Although Mr. Galileo also believed that everything in the world has its own laws, there are too many uncertainties for us to make an accurate prediction of the future. There are always too many accidents and unexpected events that disrupt our original plans."

"That's right." Bella agreed, "Actually, even if something happens, it's sometimes hard to know for sure."

"Huh?" Elena was a little surprised, "Why do you say that?"

"Because the so-called history, in fact, is only true at the moment when it happens. After that, we can only rely on our own and others' "memories" and the so-called "evidence" left by history to restore the truth as much as possible. However, in reality, people's memories are biased, and it is difficult to be 100% accurate, or it is simply impossible to do so. Because everyone's personality and habits, and even the mood at the time, will affect him to write down things. Simply put, people just jot down what they want to remember. The so-called 'evidence' of history, or relics, are only traces left by what happened, and they may be able to prove to a certain extent that they did exist, but they cannot restore the true face of history."

Elena listened quietly to Bella's words, and seemed to understand a little bit of what she meant.

"For example, the Trojan War." Béla continued, "We only hear stories about the capture of the city of Troy by the Greek coalition in Homer's epic poems. It is not known whether this war actually took place in history, and whether the city of Troy really existed. Even if the ruins of the city of Troy were discovered one day in the future, they would not be able to show the original appearance of history. It is difficult to determine whether Agamemnon and Achilles really fought Helen, how Paris and Hector held out for ten years, and even whether the Trojan massacre actually happened. We can only get a glimpse of the picture of the year through the clues left by history. In fact, the so-called truth has long been lost in the long river of history."

"And then, how do we determine history?"

"Not sure."

"Isn't that vain?"

"Perhaps, but history exists. Because our existence is the best proof of the existence of history." Bella pointed to the telescope on the shelf, "I don't know how Mr. Galileo got the inspiration, but it really exists. Maybe one day in the future, it will be replaced by more advanced technology, but people will always remember it and remember the contribution that Mr. Galileo did."

The three of them chatted leisurely for a while, until Miriam came to the rooftop again.

"Mademoiselle," said Miriam, "Mr. Merson has just sent a message that Mr. Holder is returning to Austria overnight, and that he may not be coming tonight."

"Huh?" Bella asked, surprised, "Did you mention why?"

"I don't know." Miriam replied, "The other party didn't say anything."

"In that case, then don't wait for him." Alina yawned, "It's not too early, shall we go to bed?"

Miriam put the binoculars back in the box, and Bella and Anna followed Elena downstairs.

The next morning, Elena and her party took the train back to Florence.

As soon as they got off the station, they received a message from Norton.

It turned out that Stephen rushed to Florence overnight last night, and Oland brought the magic stone. This morning, Norton had delivered it to Mr. Verrocchio's workshop.

So, Elena and the others decided to go directly to Mr. Leonardo to have a look.

"This ......" The young man who opened the door was still the same one from yesterday, "I'm sorry, senior brother suddenly received news from home yesterday, it seems that something happened, and he has rushed back overnight. He asked me to apologize to a few of them and say I'll be back as soon as I'm done."

"Did he say what it was?" Elena asked.

"I don't know, but it looks like I'm in trouble." The young man replied.

"Michelangelo," a middle-aged man walked up from behind Elena and the others, "what's wrong with your senior brother?"

It turned out that Mr. Verrocchio was on the same train as them, and he didn't notice it on the way.

"Ah, master, you're finally back." Michelangelo finally breathed a sigh of relief when he saw Monsieur Verrocchio, "If you don't come back, I really don't know what to do."

"What the hell is going on?"

"I don't know, yesterday Senior Brother's hometown sent someone to send a message to him to hurry back, as if he was in trouble." Michelangelo looked worried.

"Mr. Verrocchio." Elena spoke, "Why don't we go over and have a look later?" If Mr. Leonardo is really in trouble, maybe we can still help?"

"Really?" Michelangelo excitedly said, "That was wonderful. I'm worried about whether my brother will be in danger alone."

"That...... There are a few of them." Mr. Verrocchio bowed deeply.

Originally, he wanted to go over and see it himself, but now that he had just returned, there were a lot of things to deal with in the workshop, and he really couldn't get out of it.

"Where is Mr. Leonardo's hometown?" Elena asked.

"It's in the town of Finch on the outskirts of town." Michelangelo replied.
