"Where are you going?"

In the silence of the hallway, Lilith hurried to catch up with Arthur and asked in a low voice.

"To the secret room, of course." Arthur replied.

The Holy Grail War game is currently only one ghost away, and Peeves is the most famous ghost at Hogwarts School of Witchcraft and Wizardry, and it is impossible for Arthur to give up on him.

So it was imperative to find Myrtle as soon as possible and let the Wesley Twins bring Peeves' ghost into their Valhalla.

In this case, the number of servants in the Holy Grail War game is enough to be 7, which is enough to conduct a Holy Grail War.

Lilith frowned slightly when she heard that Arthur needed a secret room. In the past few days of investigation, she has found the entrance to the secret room in the bathroom, but it has never been clear what secret spell to use to enter.

At this time, Arthur said that he was going to take himself into the secret room, and Lilith's heart had to wonder how many secrets Arthur had on him.

Because it was a secret between the two, Lilith didn't ask anything more. It's still in a public hallway, and it's likely to be heard by someone who suddenly appears if you talk too much.

As a saint, Lilith knows how to keep secrets.

"Ah! Arthur, why are you here? Oh, Professor Lilith, you're there too!"

Just as Arthur took Lilith through the magic staircase to the third floor of the castle, the two had just turned the corner when Myrtle crashed into Arthur's body.

"Hermione, is your astronomy class over?" Arthur asked.

"Well, just after it was over, I suddenly remembered that I left my notebook in the classroom, so I came back and went."

Myrtle kept her head down, trying to hide the panic in her heart.

She didn't know how to walk near the bathroom for some reason, and when she came back to her senses, she quickly turned around and walked towards the Gryffindor common room.

Before he came to the magic staircase, he met Arthur and Lilith, and the first time he saw Arthur, Myrtle's heart was extremely excited.

She just wanted to recite the incantation silently and directly control Arthur. But Lilith also happened to appear in front of her, and Myrtle could only sigh that she was lucky to see the other party, otherwise if she directly controlled Arthur, it would not be directly exposed.

"Little sister Hermione, Notebook hasn't been answering my sister's questions much in class lately. Isn't there something on your mind?"

Lilith looked at Myrtle, who was a little flustered, and smiled slightly.

"No, no. I was just... I've been feeling a little unwell lately."

Lilith's question made Myrtle secretly say that her recent performance during class, although she tried hard to play Hermione, but she had not been in class for more than fifty years, and a lot of knowledge had long been forgotten.

In addition, she was bent on finding the secret spell to enter the Slytherin Vault, and she had no intention of reviewing what the first-year students had learned.

So in class lately, she didn't answer questions as often as Hermione used to.

The other professors were not surprised by Myrtle's performance, but they thought that "Hermione" had grown up, not as sharp as before. And the feedback of these professors also made Myrtle let her guard down.

Now hearing Lilith's inquiry, Myrtle's heart was pounding at this time, thinking that Lilith had discovered her abnormality.

"Are you feeling unwell? Then go back and rest."

Lilith looked at Myrtle's panicked and dodgy eyes, and secretly said in her heart that the little girl had finally grown up, so she didn't think about it anymore, so she asked Myrtle to go back and rest.

"Yes, Sister Lilith. Arthur, goodbye."

"Goodbye."

......

Listening to Arthur and Lilith's weaker and weaker footsteps, Myrtle was annoyed and her cheeks bulged into buns.

What a great opportunity, if it weren't for Lilith's sudden appearance, she would have been able to make Arthur her puppet just now.

Now, she doesn't have a chance to attack Arthur today.

"No hurry, I'll be looking for Arthur alone tomorrow. Taming potions will work one day. Just find Arthur before dinner tomorrow. I'm leaving

One step closer to the mantra to enter the secret room."

Myrtle muttered to herself as she walked up the magic staircase.

At the same time, Arthur and Lilith also come to the bathroom. Led by Arthur, the two came to the copper faucet marked with the snake.

「￥#&*%」

Once again, at the entrance of the chamber, Arthur was very skilled in using the serpent's old voice to speak commands.

As the hissing snake whispers rippled through the bathroom, Lilith was surprised to find that the pool in front of them had suddenly had an extra pipe to the dark abyss.

"This opens? The language you just spoke couldn't be a snake's old language, right?"

"It's the old snake, I didn't expect Professor Stienkana to know about the old snake."

"A year ago, when I was in the Americas, at the Infamorny School of Witchcraft and Wizardry, I saw Principal Fiona talk about snakes. At that time, she told me that the snake tongue was only used by the descendants of Slytherin, and that as Slytherin's descendants, the snake tongue was a language that must be learned from an early age."

"At that time, I asked Principal Fiona to teach me how to be a snake, but she was unwilling to do it no matter how much it cost me."

Lilith sighed, remembering what had happened to her at the American Invermorny School of Magic.

"Yinfalmorny? Oh, I remember that school was founded by a descendant of Slytherin, a member of the Gaunt family."

Arthur nodded when he heard this, he still knew a lot about the American Yinfamorny School of Witchcraft and Wizardry.

After all, in the book "Where Are the Magical Creatures", the heroine and the second female protagonist both graduated from Yin Famorny School of Witchcraft and Wizardry.

"Then how did you learn to be a snake, I have investigated your background."

"Before you entered Hogwarts School of Witchcraft and Wizardry, you lived in an orphanage in the Muggle world, and there is no way anyone will teach you the old way of a snake."

"Are you also from the Gaunt family?"

Lilith looked at Arthur and asked suspiciously.

"Of course not, Voldemort is the last member of the Gaunt family. I'm just an orphan. It's a secret why I'm a snake."

After Arthur finished explaining to Lilith, he raised his wand and recited the incantation.

"Fluorescent flickering."

"It's time for us to go in."

With that, Arthur climbed into the pitch-black water pipe and fell down the pipe towards the secret room.

With his previous experience, Arthur didn't feel a sense of fear in the pitch-black and bottomless water pipes.

Lilith wanted to ask about something, but it was her alone time with Arthur, and it would be a shame not to know more about Arthur's secrets in such a precious time.

But Arthur went straight down the pipe, so that she didn't have a chance to ask again.

Lilith pursed her lips and snorted coldly. It also descended down the water pipe.

Soon the two of them fell into a dark and cold space, and Lilith, who came here for the first time, suddenly became vigilant when she thought that this was the basilisk's lair.

She raised her white jade wand and watched her movements intently.

"It's still some distance from the Chamber of Secrets. Don't be so nervous."

Arthur kicked the broken bones at his feet aside, and with his memory walked towards the passage into the Slytherin chamber.

"Won't that basilisk appear? And Arthur, haven't you been here a long time ago?"

Lilith asked in a wary whisper.

"Aren't you talking nonsense?" Arthur said with a roll of his eyes.

"The basilisk is still asleep, and no one can revive him except the descendants of Slytherin. So there are no living creatures here except for the two of us."

Arthur explained to Lilith beside him as he walked forward.

"How do you know so much about this place?"

Lilith kept asking Arthur like a question girl.

"Isn't that normal, if I don't know anything about this, I

Will it bring you here?"

"That's not for sure. Maybe you already knew about it, but because of the basilisk, you didn't dare to come in."

Lilith pursed her lips, having roughly guessed that Arthur had been here before.

But... In order to get more information, she used a trick of agitation.

"When you brought me in, you asked me to be your bodyguard and let me help you deal with that basilisk."

「......」

Seeing that Arthur was silent, Lilith said again, "If you don't speak, is it... I'm right. Debunking your true thoughts, you are so angry that you don't want to talk anymore."

"Hee-hee, are you a kid after all? Sister, they all understand."

In order to get Arthur to break the defense, Lilith once again added fuel to the fire.

And Arthur, who heard this, suddenly stopped, looked up at Lilith indifferently.

Seeing this, Lilith thought that what she said was really Arthur's inner thoughts, and was just about to comfort Arthur in the tone of an elder.

But before she could speak, she heard Arthur's cold words.

"You talk a lot, and you like all kinds of non-nutritious brain supplements. The old man sent you here, will he really be reassured?"

"He's the great Lord Grindelwald. If you call him disrespectful again, be careful that I am not polite to you."

Lilith looked angry and whispered to Arthur.

"There's the Slytherin Chamber of Secrets up ahead, you can help me see if Myrtle is here."

Arthur chose to ignore Lilith's angry look, and when he came to the familiar space with towering serpent pillars erected on both sides, he found that he couldn't find Myrtle's figure at all. He enlisted Lilith's help.

"You apologize to me first, or I won't help you find Myrtle."

As a saint, Lilith would never budge when it came to Grindelwald.

Even if Arthur now holds her handle and knows her true identity.

「......」

Arthur was a little speechless, didn't he just call Grindelwald an old man. A centenarian, called an old man, there is nothing wrong with it.

Why does Lilith care so much, is this a fanatic?

"Well, I apologize to you for your rudeness. It's me who is wrong, please forgive me."

In order to be able to find Myrtle, Arthur can only apologize to Lilith.

As the saying goes, a big husband can bend and stretch, and in order for the Holy Grail War game to be completed as soon as possible, it is not difficult to apologize in front of Lilith.

"That's pretty much it, huh." Lilith straightened her nose and the anger on her face quickly dissipated.

She looked up and took a closer look around her, two rows of towering serpent pillars that had sunk into the darkness. At the end of the front, there is a huge statue of a wizard.

The dreary air, coupled with the traces of time left on the serpent pillars, floors, and statues.

All this indicates that this place was built hundreds of years ago, by Slytherin, the founder of Hogwarts School of Witchcraft and Wizardry.

"The Ghost Manifests!"

Lilith waved her wand and cast a powerful spell, ready to summon all the ghosts hiding here.

But a few minutes passed, and the entire space was silent, except for the sound of himself and Arthur's breathing, not a single ghost was heard or seen at all.

"Looks like the ghost isn't here." Lilith said regretfully to Arthur.

"yes, hell really. The whole of Hogwarts is so big, where the hell did Myrtle go?"

Arthur said in annoyance. At this moment, he can't wait to directly take on a foreign debt, pay to activate his writing ability, and let Myrtle appear.

Really, the disappearance of Myrtle is a very outrageous thing. Lilith also told him that Myrtle was still in Hogwarts Castle at this time.

Incomprehensible, weird, outrageous.

Arthur rummaged through the fragments of his awakened memories, trying to find some memories that he had overlooked.

But no matter how many times he recalled, he couldn't find any information about Myrtle's disappearance.

"Arthur, do you feel anything..."

Just as Arthur was about to leave the secret room, Lilith's face suddenly changed and she said in a deep voice.

"What?" Arthur looked at Lilith, and he frowned slightly at her rare serious expression.

"If I'm not mistaken, there's a very evil aura coming from the statue heading to Slytherin."

Lilith aimed the white jade wand in her hand at the Slytherin Sculpture, and then pressed closer.

Arthur improved his sensing ability, but he did not sense the evil aura that Lilith said, but saw that Lilith was uncharacteristically serious.

He also clutched his wand and followed Lilith as he walked towards the statue of Slytherin.

"Huh? How did this statue crack?!"

When the two of them came to the bottom of the Slytherin statue, the attentive Arthur suddenly noticed that the statue in front of him had a few more cracks than the statue he had seen before he came last time.

"Arthur, there's good news and bad news. Which one do you want to hear?"

"Myrtle in the statue?" Arthur asked.

"No, it's this statue that seals a monster that is just as terrifying as the monster you killed. But the seal on this monster has been loosened, and in the near future, it will break through the seal......

Lilith looked at the cracks in the statue, they were all new, and the evil aura that made her hair stand on end was leaking from them.

With her years of adventures around the world, she was sure that this Slytherin statue must have sealed a terrifying monster of the same level as the octopus monster.

"Hogwarts School of Witchcraft and Wizardry, it's dangerous everywhere. If this monster breaks through the seal, the lives of the students above will be threatened again."

Lilith came to Hogwarts School of Witchcraft and Wizardry on a mission to protect Arthur. But when she found out that there was also a terrifying monster sealed here, she couldn't help but feel sympathy for the little wizards above.
