There wasn't much time in Dumbledore's office, and it wasn't curfew time before Lind returned to the Gryffindor common room.

Back in the dormitory, as usual, he first went to the bathroom to wash up, and then he sat on the bed with the book of "The Revelation of the Tide" in his hand.

The lyre, also known as the poetic lyre, is said to have been invented by Hermes of Greece: one day, Hermes was walking in the wilderness and accidentally stepped on something that could be pronounced, and when he picked it up, it turned out to be a turtle shell with a tendon on it, which was pronounced due to vibration.

Hermes got his inspiration from here, and he later used a tortoise shell as a base and a cowhide as a resonance box. It was supported by two calf horns, a beam between the upper parts, and four strings (tendons) on it, thus making the world's first lyre.

In later developments, Delpende, known as the father of Greek music, increased the four strings of the lyre to five and seven strings.

The lyre recorded in the book is the most commonly used lyre, which also echoes the statue seen in the fish-man village.

Although the lyre was invented by Hermes in legend, people prefer to associate it with Apollo, the god of light and literature.

The sound of the piano is melodious, civilized and demure, which also echoes the Apollo depicted in Greek mythology. Apollo is depicted in mythology as a versatile, upright and kind, the most beautiful and handsome deity.

The first step in the ritual is to make a musical instrument, and Linde chose to make the lyre, not because of anything else, but simply because the book contains notes on the making of the lyre by a latecomer.

The first is the most important "resonance box" for the body. Kill a magical animal with your own hands and soak its skull mixed with your own blood and seawater for a month.

This alludes to the legend of Hermes making the lyre, and also reflects the ancient naïve magic theory and the animal worship ideas of the time.

And at that time, there were often heroic legends of hunting magical beasts in Greek mythology, the most famous of which was Hercules Hercules hunting the hydra monster Hydra.

Although it was still unclear to Lind what the absolute connection between these ancient myths and legends and the history of magic was, he thought about them after a little divergent thinking.

Linde's hands caressed the book, and his mind recalled the information he had found about Apollo and the lyre.

"The sound of the piano is melodious, civilized and demure......"

Civilized and quiet......

If I'm not mistaken, it seems like one of these creatures is about to die.

As long as he appeared at the right time, he drove away the guy who hunted it in the first place, and then ended its life in the name of reducing the pain.

Then this is considered to have been killed by his own hands.

But as an animal of light, that is, I can't put on any hypocritical pretense in front of it, or it will detect my bad intentions and curse me after death - unless I learn Occlumency.

It is necessary to achieve the mentality of "I really want to save it" and the behavior of "I will kill it with my own hands" at the same time......

Linde stood up and looked out the window at the end of the Forbidden Forest, thinking of a countermeasure.

He also doesn't know how long he has been standing, which is a very contradictory thing, there is a lot of room for maneuver but a small success rate......

It wasn't until his roommates yelled and walked back to the dormitory that he came back to his senses and lay down on the bed as if he was about to sleep.

"Forget it, I still have to give priority to 'saving' first, and if I can really save it, I just don't kill it. And watch out for Quirrell. Linde patted his head and smiled a little self-deprecatingly. He wasn't a Gryffindor.

Even if he didn't get the unicorn's head, Linde also had some other filings in his heart. Unicorns are relatively easy to get for me now.

If he doesn't get it, he will choose something more 'convenient and powerful'. The double horns that come with certain creatures are inherently good for making lyres.

For example, a certain underage fire dragon, of course, he didn't want to plan Hagrid's fire dragon, but Hagrid's incident gave him a wake-up call.

In the plot, Hagrid's fire dragon Noble grows extremely fast, and Linde may also be able to commit suicide by autotrophic suicide of this creature with a very short growth cycle.

In his previous life, he had fed pigs and sheep. But I never had a cat or a dog.

He understands other people's feelings for pets, so he doesn't plan a ready-made Hagrid's fire dragon.

But he could raise one of his own and kill it like a pig.

Thinking of this, Linde really felt like a Slytherin. He really doesn't care about what life is not life.

Subsequently, Linde gave Andersen a new task:

Spy on Hagrid's Cottage and Harry Potter and his party.

The plan for the resonance box had a rough outline, and then he began to ponder the strings again.

The strings must be some linear objects with strong toughness.

For example, the tendons of living things, or the nerves of some organisms with extremely thick nerves.

Although you can also buy things such as dragon tendons and dragon nerves in the pharmacies in Diagon Alley, those are all concocted in various ways for the convenience of selling and preservation.

I don't know if there is any way to contact the owner of the pharmacy and ask for some fresh goods. If you send a letter directly, it is estimated that the other party will not pay attention to you.

Or some metal or plant material with high-strength magic conductivity......

Thinking about it, Linde couldn't help but sigh. Making the lyre is only the first step in becoming a sea singer, and the subsequent rituals are much more tedious and long!

Thinking about it, Linde decided to take the first step first, looking at Dumbledore's communication with himself today, he did give himself a lot of freedom. But that doesn't mean he can be unscrupulous.

So for some details, he decided to be more steady.

At this time, the roommates were almost asleep, not because they were sleeping too fast, but because Linde was thinking too much about himself.

After waiting for a while, he got up and changed into a black robe, and with the help of Hans Christian Andersen, he came to the Room of Need.

Then he instructed Andersen to go back to spy on Harry Potter, he is a kid who travels at night at every turn, and he can't remember the specific time of the fire dragon incident, so it's better to start doing it now.

After telling Andersen that he was almost ready to pick him up, he went into the room where he practiced spells, and he didn't just tell Andersen to say, "If you think of it, start doing it now," but he himself too.

He had drafted a letter, which he intended to send to Felix to-morrow morning, with some generous gold gallons attached.

Felix then contacted Diagon Alley to buy things, and he sent them over.

In this way, the items sent will not have serious traces of "goods", but "family items". It's like when you bought an inflatable. The result was sent directly to the front desk of the company, and the young lady at the front desk saw it at a glance......

In short, safety comes first. He really didn't know how much Dumbledore had control over the school.

And the characteristics of what he wants to buy are still obvious. A polymath like Dumbledore could see the whole picture of most things.

When the time comes, I'll ask Felix to buy a random Traceless Telescopic Charm bag in Diagon Alley, and stuff those things into it.

It was also the safest way he could think of at this stage, albeit with some trouble.
