Said to be an adventure, in fact, the three of them simply visited the first and second floors of the castle, the first floor is the living room where you have just eaten, as well as the study and other infrastructure, the second floor is mainly the guest room, and the third floor is the attic for storage.

"It's boring!" Upon returning to Bella's room, Elena grumbled in frustration.

I thought there would be some new discovery, but I was disappointed.

"If it's so easy to discover, it's not a secret!" Bella quipped.

"I'm not reconciled." Elena pouted, "It must be the wrong time, let's go back in the evening!"

"......" Bella didn't know what to say.

She couldn't stop Elena's intense curiosity.

However, before leaving, my father also explained that he should pay attention to the situation of the castle.

Although the Carlos family does not care much about the so-called secrets. But since you've already received an invitation, it's better to attend as a courtesy.

So he asked the two sisters to go to the banquet on behalf of the family. By the way, go through the experience.

"Be safe!"

In the end, my father only emphasized this sentence.

At this moment, the three ladies decided to stay in their rooms and rest.

Bella took out a fantasy novel "The War of Tiamat" from her luggage, opened the bookmark, and began to read.

Anna took the cookies she had received from the maid as she had just passed by the kitchen, and ate them with relish.

However, it didn't take long for Elena to sit still.

"No, I'll suffocate if I stay." Alina stood up impatiently.

She's a lively and active type, and she's majoring in fire magic, so it's not her style to stay quiet.

"Didn't you say you'd wait until evening?" Bella put down the book in her hand.

"But I can't stand it! It's so quiet around and there's nothing lively at all. Who the hell wanted to build a castle in such a hellish place?" Elena frowned and grabbed her hair with both hands, as if she was going to pick herself up, "It's so boring——!

Just then, a violent explosion was heard downstairs.

The ground and walls trembled a little, and I don't know what was happening.

Elena, however, seemed to smell the shocking news, and rushed out impatiently.

Bella had no choice but to put away the book, press the bookmark, and follow with Anna.

The explosion came from the basement of the first floor.

Because of the strong noise, everyone was attracted to it.

"Yes...... There are demons!" Duke James looked disgraced.

"Sir, as a housekeeper, I have to warn you that it is very dangerous to use demolition indoors." Yuri said as he lifted the Duke on the ground.

I didn't expect Duke James to be so stout, but his courage was really a little small.

"Huh? Are there any demons? Really?" Elena became interested, "Where? Where?"

"That...... Over there......" The Duke trembled and stretched out his right hand, pointing to the utility room in front of him.

When everyone heard this, they immediately made a defensive posture.

Elena couldn't suppress her curiosity and volunteered to go up and investigate, but was blocked by Holder.

"It's better to leave this kind of dangerous thing to a man." The prince said in a gentlemanly manner,

Elena thought for a moment and felt that this made sense.

"Okay, be careful, then."

Holder picked up an oil lamp on the wall, carefully pushed open the debris of the door that had been blown to pieces, and searched very cautiously.

Quietly inside the utility room.

After about a few minutes, Holder stepped back and shook his head solemnly.

"No way, I saw it!" The Duke couldn't believe it, "Was it blown up by my blast?"

"If it's really a demon, a simple blast wouldn't have been fatal to it." The prince replied earnestly.

"Could it be that they are hiding?" The pastor analyzed.

"But there's not the slightest sign of it."

"Is it possible that you took the opportunity to escape just when we came in?" The professor suggested another possibility.

"Impossible," said the butler, "I happened to come down to get the red wine for tomorrow's breakfast, and when I heard the explosion, I rushed over as soon as I heard it, and I didn't encounter any demons or anything like that on the way."

"This ...... How is this possible?" The Duke still wouldn't believe it.

"Hmph, just a demon spirit is scared like this, it's really a useless man." Lady Isabel, who is taciturn, is very sharp as soon as she speaks.

"What? Who do you say is cowardly?" The Duke was so angry that his hair stood on end, he had never been so slighted, "I was just careless, startled. Now that thing is probably so frightened by me that I don't dare to show up!"

"Alright, let's calm down." The pastor conciled, "For God's sake, let's go back to it. It's okay to stay here all the time."

So, everyone went back to the hall on the first floor.

Everyone discussed the accident just now for a long time, but there was no substantive progress.

"But then again, what are you doing in the basement?" The prince asked curiously.

"Hmph, of course I'm looking for secrets!" James took it for granted.

"You're pretty straightforward."

"Of course. What is there to hide, anyway, aren't all here here for this?"

Holder was noncommittal.

"Is it possible that the castle owner deliberately hid to scare us?" The pastor reasoned.

"Jokes, just demons, just scare the cowards." Isabel drank the black tea brought by the maid and said coldly.

"You!" The Duke stood up in anger, feeling himself insulted again.

"Don't get angry yet." The priest reassured, "But there is some truth in Madame's words. To scare us, you can't rely on such things as demons alone."

"That's right, none of you here are ordinary people, and it's really easy to deal with a little demon spirit." The prince took a sip of black tea and continued to elaborate on his point, "And even then, there is no corresponding motive, right? Did the lord of the castle invite us all the way to come over just for the sake of mischief? - That's a lot of fun, isn't it?"

"That's it." The professor interjected, "There must be some ulterior secret that would be used to cover people's eyes and ears in this way."

"Will it ...... What does that secret have to do with it?" The Duke asked.

Everyone looked at each other.

Obviously, whatever the purpose of the castle lord who invited everyone here, it should be expected that everyone's purpose must be inseparable from that rumored secret.

"Anyway, there's no going to be any progress here." Holder put down his teacup and stood up, "Even if the demon spirit goes and returns, there are so many of us, it will not dare to act rashly. Maybe we'll find something out of our separate actions."

Everyone felt that the prince's words were very reasonable, and it was not too early, so they decided to go back to their rooms.

Except for the butler and the maids, who stayed behind to clean up, everyone else left the hall.

Elena also planned to go upstairs to rest, but when she turned around, she found that Bella was still in place, her eyes as if she were looking at the butler.

"What's wrong?" Elena asked, puzzled.

"Ah, nothing." Bella came back to her senses, smiled, and followed Anna.

Elena said goodbye to the Carlos sisters and returned to her room.

I thought that things would come to an end temporarily, but this night was not destined to be peaceful.

Elena lay in bed, tossing and turning, unable to sleep.

Thinking back to what happened today, it became more and more difficult for her to sleep.

In the end, I couldn't help it, so I got up and went next door and knocked on Sister Carlos's room.

Bella was still reading the fantasy novel of the day, while Anna was lying on the bedside savoring the macarons that had just been brought from the dinner plate.

"Hey, you two haven't slept yet?" Elena greeted with a smile.

"Please come in." Bella turned to her side and let Elena in.

The moon outside the window was already hanging high.

The sea is noisy during the day, but it is quite quiet at night.

Several windmills in the field rotate slowly, illuminated by the starry sky, which has a unique artistic conception.

"Now, I said Bella, what happened to you?" Elena recalls how Bella looked before going upstairs.

"Hmm......" Bella bit her lip thoughtfully, "Did you notice that Mr. Yuri is a little weird?"

"Huh?" Elena was confused for a moment.

"Do you remember when you were in the cellar? - After Duke James encountered the demonic spirit, Mr. Yuli rushed to the scene as soon as possible."

"Remember, he said he was going down to get red wine, that's why he was so close to the scene, right?"

"Wine for tomorrow's breakfast, to be exact."

"Is there any difference?" Elena didn't understand what Bella meant.

"When we visited here in the afternoon, I remembered that the kitchen on the first floor didn't seem to have a freezer or anything like that, right?"

"Well, I haven't seen it either."

"Then here's the problem. If it's the red wine for breakfast tomorrow, take it out now, and there are no preservation measures, and tomorrow morning, I'm afraid it won't be fresh, right?" Bella voiced her doubts, "Mr. Yuri is a cautious man—as evidenced by the letters he carried with him at the dinner—so how could such a mistake could occur with such a cautious person?"

"Uh...... Could it be that Mr. Ully has other arrangements tomorrow morning, so get the wine ready in advance?"

"Even so, he can tell his servants in advance and go down tomorrow morning to get it, right?"

"This ......"

Elena was speechless.

Hearing Bella say this, she also felt that the butler's explanation was a little strange.

Just as the two were talking, a scream came from the hallway outside the door.
