The three of them returned to the study.

Elena and Holder continue to search the shelves for valuable clues, while Bella begins to study Lady Isabel's Red Book.

"It's a family tree." Bella said, flipping through the pages.

"What genealogy?" Elena asked.

"It's the genealogy of the owners of this castle, the Valdraz family, hundreds of years ago."

"Huh? Really?" Elena left the bookshelf and leaned in.

It contains a summary of the life of more than a dozen generations of Valdraz family heads. Some of them held important positions in a certain country, some were rich in the world, and some even led wars......

"It's really talented!" Elena couldn't help but sigh.

Indeed, the Valdraz family was once very prosperous and had considerable influence on the European continent. The status is the same as that of today's Medici or Habsburgs.

It's just that 500 years ago, this mysterious family suddenly died down and disappeared from people's sight, and then gradually faded into oblivion.

And the record of this family tree also ends with the last head of the family, Elio Valdraz.

Elio was a navigator who loved to study and explore, and was proficient in astrology and alchemy, as well as botany and mineralogy. He has a wife and a daughter, but no son.

However, according to the previous records, the heads of the previous dynasties are not necessarily men, as long as they are descendants of the family bloodline, they can succeed to the castle master.

"Could it be that Elio's daughter is not married, so she is no heir?" Elena speculated.

"No," Bella asked, "Even if Elio's daughter has no descendants, then it stands to reason that this daughter should be the last to be in charge." However, nothing has been recorded since then. Unless—"

Bella didn't go on.

"Unless, this daughter died young, before Elio died." Mr. Holder took over.

"So, that 'beloved', Yachi's daughter?" Elena said.

"Not impossible." Bella replied.

According to the clues currently available, if the last castle lord traveled all over the world to save his daughter, trying to find a feasible way. Maybe it's medicine, or magic. In short, in the far east, he found a way. Although the cost was relatively high, he was still willing to give it a try, and did not hesitate to exchange the forbidden art that had been passed down from generation to generation in his family. - Then the sentence on the manuscript will make sense.

But is that really the case?

Bella still had some doubts.

After all, there is now insufficient evidence to make accurate assertions.

But she felt that she was getting closer and closer to the truth.

Keep turning back, and the paper behind you is blank. Until the last page, there was such a paragraph-

"Even if I become a demon, I will save you who are pure.

Even if we all cease to exist, she can go on with her life.

I don't know if it's a gift or a curse."

Bella was puzzled, but she felt an inexplicable aura of sadness, which flowed between the lines.

It's like being in the spring when everything is recovering, but you see the scenery of the grass and trees withering and withering.

Lonely and helpless.

What a mood these words were written.

is full of despair, and there is a stubbornness that is unwilling to give up.

It was as if a drowning man had grasped a straw floating on the water's surface. I know that there is little hope, but I still can't help but hope for extravagance.

Perhaps, this is fate.

"What is this?" Mr. Holder seems to have made a discovery.

Elena and Bella turned to look.

I saw Mr. Holder touching the gap in the baffle behind the bookshelf with his hand, knocking left and right from time to time.

"It's hollow." Holder said, removing all the books from this floor.

He continued to grope with his hands, looking for a long time, as if he had found the position, and then opened a dark grid.

Inside was a purple box.

"It's ......," Holder stared at what he was holding.

There is no superfluous ornamentation around the body, but the material texture is excellent.

"Open it and take a look." Elena suggested.

Holder tried, but failed.

It's not locked, but it's immovable.

"Let me see."

Bella took the box, gently placed a hand on it, and closed her eyes.

She possesses the ability to perceive the makeup of magic.

"There are seals," Bella said, "that seem to be pointed, and only certain people can open them."

"Can you break it?" Elena asked.

"It's hard." Bella replied, "There are more than a dozen layers of defensive magic applied on it, and if you want to forcibly crack it, I'm afraid you need magician-level mana to do it."

"Huh? What should I do......" Elena frowned and pursed her lips, "It's so mysterious, it's even more curious."

"Don't worry." Bella smiled and said, "Maybe somebody will open it for us when the time comes?"

Bella always felt that among the few people who went to the banquet this time, there were many hidden identities.

Perhaps, some of them can open this box.

"Okay." Elena could only give up for the time being.

Despite this, she couldn't suppress her intense curiosity, and every now and then she picked up the box and shook it twice, trying to guess what was inside by the sound. The results were all in vain.

Holder looked at Elena's distressed expression like a child with a toy, and couldn't help but laugh dumbly.

Bella had no interest in the box, but sat at her desk and compared the yellowed manuscript with Lady Isabel's Red Book to see if she could make any new discoveries.

Before you know it, the moon has risen over the sea level.

The three of them studied in the study for a while, but they couldn't find any valuable clues, so they decided to stop here today.

Saying goodbye to Elena and Holder, Bella did not go back immediately, but took the box and knocked on Isabel's room.

Madame also kept a diary on her desk.

"I'll put this with you first, okay?" Bella handed the things forward.

"No problem." Madame took the box, opened the drawer of the table, and put it in.

"There's one more thing I'd like to ask you to help with."

"What's the matter?"

Bella did not answer immediately, but gently leaned into Isabel's ear and said a few words very cautiously.

"It's not that hard." Madame replied, "Wait a moment."

"Don't you ask me why?" Bella was surprised.

"If you want to say, when the time is right, you'll tell me." Isabel said with a smile.

"Thank you so much for trusting me." Bella bowed sincerely.

"I can't be wrong." As she spoke, Madame handed Bella an envelope-like object, "You're a kind child. But sometimes, kindness isn't necessarily a good thing."

"Huh?" Bella took the envelope with a puzzled expression.

"You'll find out later." Isabel nodded.

Since the lady said so, Bella didn't ask any more.

"Thank you again."

Bella thanked her and left with the envelope.

"This kid......" Isabel muttered to herself, "a little like when I was younger."

When Bella returned to her room, Anna was fighting a chunk of French Mont Blanc.

Resisting the urge to support her sister, she walked to the window and closed the curtains.

Bella then handed the envelope to Anna and gave a few brief explanations.

"Oh." Anna replied without looking up.

"Don't make a mistake." Bella admonished again.

"Don't worry, no problem." Anna said lightly, "Would you like some sister?"

"I don't eat !!"
