"Tick... Tick..."

In a dark and deep place, the empty sound of dripping water echoes day after day. The dull and humid air flows slowly here, mixed with unspeakable pollution and smell.

Occasionally, there will be a string of voices heard in the dark. They approached from a distance and then kicked away in a hurry.

Those little passers-by are mostly just mice.

Basically, no one will come here. There are only snakes, insects, mice and ants living with humans in the city, which add some unknown vitality to the deep and empty underground world.

Yes, it should be like this. It's dirty but calm, gloomy but not dangerous. It's a "pure land" built by people under the bustling city.

But recently

"Hiss -"

Accompanied by a chilling low hiss, a small friction sound came from a distance, and there was a tendency to be louder and louder.

As the friction sound approached, even the ground began to shake slightly, as if some giant was approaching quickly in the endless darkness.

Before long, the movement slowly turned into a rumbling vibration, and the hiss became more and more penetrating.

Finally, when a group of mice were driven away with squeaks and cries, the sound that had come near suddenly stopped. Then, a pair of huge eyes glittering with miserable green light suddenly appeared in the dark.

"Don't stop. You haven't reached the place yet."

Suddenly, a voice sounded near the eyes. It was a man's voice. I heard that voice was a little old, but it was extraordinarily calm.

As soon as the voice settled, the eyes suddenly disappeared again. Immediately after that, the rumble sounded again, carrying a gust of fishy wind. After a while, I heard it swagger away.

For a long time, the initial dripping sound appeared again - it still echoed in the wide channel according to the original rhythm.

……

At more than three in the afternoon, Mrs. padev teahouse.

Here, while drinking black tea and tasting dessert, Maka and Hermione chatted, and finally did not pick up the teapot that had been renewed and pour it into the empty teacup.

Although they talked happily after that, as if there were countless things to talk about.

From the men and women in the teahouse to Hogwarts' classmates and professors, and then to the wonders of the whole magic world, Maka and Hermione, who are both well-informed, will never lack topics.

But no matter how much we talked, we wouldn't spend a whole afternoon here.

"What time is it? After drinking a lot of tea, they should almost 'get down to business'?"

Outside a window of the teahouse, a furtive voice sounded from under the windowsill. People familiar with it must be able to hear it at once - it was Ron's voice.

And then another voice came out, which seemed to be weak:

"Ron, forget it! Marca and Hermione are dating. It's not good for us to peek like this... Besides, my legs are numb."

"Neville, can't you hold on!" Ron said helplessly, "your legs are numb... Do you think I'm not numb? Look at your girlfriend Hannah, the girls haven't shouted a word of fatigue!"

"Because she's already sitting on the ground!" Neville said bitterly, "I was going to sit, but seeing you squatting all the time, I have to insist with you..."

"Oh!" Ron patted Neville on the shoulder when he heard the speech. "Hey, OK! He's really my good friend!"

But unexpectedly, with such a shot, Neville could no longer squat. As soon as he tilted his body, he fell to the root of the wall.

The passers-by looked at them, squatting and leaning down, and looked at them with a pair of subtle eyes, so that Hannah, sitting silently next to Neville, couldn't help covering her face.

Although she is satisfied just to be with her boyfriend, she still can't stand such a shameful behavior.

"Neville, shall we go?"

"No, wait a little longer!"

Ron couldn't help saying happily that although Neville complained, he could still refuse Hannah's proposal to leave

"I knew our friendship was the strongest!"

However, Neville, who collapsed to the ground, immediately shook his head decisively.

"What friendship?" I saw him rubbing his legs in pain and sighing, "I just have no consciousness in my legs. I can't go if I want to go!"

"Puff -"

A chuckle suddenly rang out from the three sides, making Neville look back hard, and Hannah, who covered her face, quickly separated her fingers and looked at it.

"Hermione? Ma... Oh!"

Ron, who was still trying to squat under the windowsill, turned his head and finally couldn't keep his balance with his sore legs, so that he fell on the ground at once.

"I'm not tired after squatting for so long, but it's hard for you!" Marca, standing next to Hermione, smiled. "Hermione and I just talked about a new library in Diagon lane. We're going to go there - how about you? Are you interested in going with us?"

"Of course!" Ron didn't feel dirty, so he turned over and lay on his back, "but... Marca, do you have any magic medicine to relieve leg numbness?"

The numbness of his and Neville's legs is nothing more than the poor blood flow caused by squatting for a long time. Even if they don't care, they will recover themselves in a while. Maka just took out a small bottle and gave them a sip. Soon they ran and jumped to their feet.

Then Ron raised his hand and waved:

"Let's go!"

……

A few minutes later, in the backyard of the broken cauldron bar, five figures appeared together in a burst of space distortion.

After demaka knocked on the courtyard wall and entered the crowded diagonal lane, Ron suddenly stretched out his hand and stopped Neville and Hannah behind him.

"What's the matter?" Hermione looked at him suspiciously.

In fact, not only Hermione, but also Neville and Hannah duy looked at him with a puzzled face.

"Hmm?" said Ron hehe with a smile. "Let's have a look here and go later... You and Marca go first! Don't wait for us."

Speaking of this, his meaning has been very clear. This is to carry out "peeping" to the end!

"You're coming with me. Is that meaningful?" Marca waved her hand. "Don't poke your head like a fool in the back. Let's go shopping together!"

After that, he and Hermione took Neville and Hannah along. Ron hesitated for a long time before he had to catch up in a hurry.

"... this can be regarded as a 'date'!"

Although Ron knows something about Marca, Hermione and Luna, the complex relationship between them is not what Ron can understand.

In fact, it's hard for them to make it clear, not to mention friends like Ron.

The significance of this date, in fact, does not lie in what they did, but mainly in the mutual statement between Hermione and Luna.

Since the "seeker duel", the two girls have officially changed from "stalemate" to "competition". Although they are still good friends, they probably won't compromise with each other as before.

Of course, as far as the current situation is concerned, the real competition will not be fully implemented until the Haier wave incident is completely over.

It is precisely because Marca finally understood their ideas after Luna said the word "date", so she took Hermione out today.

"Hmm? Is this what you call the library? It doesn't look very good?"

Not long after, Maka led the four people to the front door of a store next to Ollivander's wand store. He first looked inside the store, and then looked up at the sign above the gate.

Ron said "not so good" because the sign looked so ordinary.

"Old buddy opened it," Maka said casually. "After resigning, he thought a lot at home alone. Finally, he sorted out the private library at home - little buddy liked reading very much. It is said that he had read many books here."

It can be seen that on the sign is a large brass key, which is quite familiar in style. It is the one hanging around the neck of the little buddy crouch who died under him.

It was because little buddy pulled out the key before he died that old buddy, who was locked up and almost died of thirst, was saved.

After Maka showed him his son's last performance with a meditation basin, the tough old man all his life bent down and had a straight back.

"The 'copper key library'... What a simple and rough name!" Ron shrugged, but was surprised. "You just said 'old buddy'? Is buddy crouch, the last director of the Department of International Magic exchange and cooperation of the Ministry of magic?"

"Yes!"

Maka nodded.

Back then, old buddy was known as the most promising person to become the Minister of magic, and he once won a lot of prestige because of his clear attitude against Voldemort.

However, in the end, he resigned sadly because of his son, and suddenly became a civilian from a senior official of the Ministry of magic.

"Come on! Go in and have a look... It's said that old buddy has adopted two children, a man and a woman, and they are ordinary Muggle orphans. It seems that he has completely figured it out..."

Although no third person in the world can understand the store name "copper key", at least old buddy has taken the first step after his son's death.

The past is not so important to others.

"Mr. crouch? I came to see you... Mr. crouch?"

"Sir, are you an acquaintance of Grandpa?"

A teenage girl stood by the door and asked timidly.
