That was the people that were guarding the duke's mansion were the most loyal subordinate of the duke or else the duke wouldn't let them guard here. As there's a possibility that the guard will discover his secret. That's why the duke didn't let anyone guard this mansion.

"If it's like this... It's easier to sneak inside." Souta said in a low voice. It's not that he's complaining. That's to this, it made his work easy than he thought.

He suddenly stopped as he saw that the soul he got in his earring increased. It increased by two souls. It seems that someone died right now. If he turned back now and roam around the dukedom. There's a possibility that he will find the culprit.

'Should I go back or not?' He pondered what he should. It was then that Saya's voice sounded in his head.

'You're here so you should finish what you have to do first. Also, the chances of you finding the culprit in this huge place is less than fifty percent.'

Souta looked over and saw the guards were gone. It's time to proceed forward.

Souta stood up and swiftly went beside the duke's mansion. He looked up and saw the window on the second floor of the mansion was open.

He climbed up and when he saw that there's no person inside, he entered the room through the window.

"What's with this room?" Souta muttered as he looked around the room.

The room looks normal. It has a simple bed and a table on the side but the interior design of the room was exquisite. As expected of the duke's mansion. Different books were neatly arranged in the corner of the room.

Souta walked towards the table and placed his finger on top of his. The dust was already formed on top of the table.

"Did they forget to clean this room?" Souta muttered a question. He didn't think that anyone would forget to clean this room.

He stretched out his hand and picked up a notebook on the side of the table. Souta patted the dust on it before he opened it.

"I'm Soraya, a maid inside the duke's mansion. The maid here has different roles and my role is to take care of the duke's children. I like this job of mine as the children are kind and understanding."

Souta found that this was the diary of a maid that took care of the duke's children. He continued to read the rest.

"Today, I felt that something changed in this place. The duke got a sickness and the rest of his family. Of course, they didn't let the people know this. Only the maids and some of the guards knew the condition of the duke and his family.

"And the result was stunning... The doctor said that he didn't know the disease of the duke and his family. The doctor hasn't encountered this type of disease for the rest of his life. Even the healing spell didn't show any effect.

"Some of the maids like me showed an expression that they will leave the duke's mansion. They are afraid that they will catch the same disease. They don't have money so it's natural to feel that way. Me too, I wanted to leave this place but I'm concerned about the well-being of the children."

Disease? Souta read it once again and didn't say anything about the symptoms of the disease. In the end, she was just an ordinary maid and didn't have much knowledge of the duke's disease. That's the reason why she didn't bother herself taking it down in her diary.

'Next page... I think I have an idea about it.' Souta heard Saya's voice in his mind. He turned to the next page and continued to read the diary along with Saya.

"Today, a miracle happened. The duke and his family recovered from their illness. It was so sudden that they could already walk and talked like a normal person. Everyone was happy for them including me.

"Today, I've received a news that some of the people in the dukedom were killed. All of their internal organs were gone. I got scared when I received this piece of news but then I remembered that I'm in the safest place in this dukedom so I don't have to worry about myself. I'm sure that all the guards were going to capture the perpetrator in no time."

Souta frowned when he read this passage. It seems that the killings in this dukedom weren't ordinary. The internal organs of the people that died were gone. No sane person will do this. Even Souta will not do this to the person that he killed.

He will not hesitate to kill his enemy but taking their internal organs and using them for some kind of ritual. That's insane.

'You're disgusting you know. What you did to the people that you kill was even worse than this. You're taking all of their soul and preventing to live another life. That's the worse for me. You're sending them into oblivion.' Saya's voice sounded in his mind.

Souta ignored her and he continued to read the diary.

"Today, some of the maids that stayed here left the mansion. I don't know why. They just suddenly leave without telling anyone. At the same time, the killings in the dukedom appeared in my mind.

"Today is the duke's first wife's birthday. The maids were preparing for a banquet. Everyone should be happy on this occasion but I found that they all have the same plain face. They don't show any emotion including the duke's children. It's weird.

"It's weird... Everything is weird. I don't want to stay here anymore. Right now, only five maids were working here in the duke's mansion. The rest of the maids were gone and I didn't even hear anything about them. It's impossible for them, including my roommate, to leave without saying anything.

"I'm going to leave this place... Actually, I found the duke's wife eating my roommate in the basement of the mansion. It scared me. Even now while writing this I couldn't get that thing out of my mind... I'm packing up my things and will leave this place tonight."

The diary ends in that passage.

Souta closed the notebook and placed it back on top of the table.

"Soraya, thanks for the information." He muttered in a low voice and thought that the maid was dead. If she knew that, there's no way that the duke will let her leave this place. The same must be said from the rest of the maids here.

They were all dead.

But Souta gained a lot of information from this diary.

The guards hid the thing that all people that died in the killings didn't have any internal organ at all. They were brutally killed.

"So why are they taking put all the internal organs? Also, why the made vanished in this mansion." Souta muttered as he rubbed his chin. He then recalled something that he read in the diary.

The basement. The place where the maid saw the duke's wife eating her roommate.

Souta walked towards the door and he decided to know everything now that he's here in the duke mansion. Everything will come into light as long as he discovered the key information in these killings.

He placed his ear on the door and tried to sense if there were people in the hallway. After making sure that no one was in the hallway, Souta opened the door and exited the maid's room.

This mansion looked deserted. It feels different inside than outside the mansion. The atmosphere here was chilly.

Souta stopped on his track as he felt the ground slightly shake. If he wasn't focusing on his surroundings, Souta wouldn't be able to sense it at all.

He frowned and looked outside the window. He guessed that the tremors came in the underground and the cause of it was his party members.

"It seems that something is hiding there in the ground," Souta muttered and he shook his head. He ignored the tremor in the ground and focused on the task in front of him.

...

Souta checked all the rooms on the second floor. He discovered that all the rooms here were abandoned for a long time now. No one was living here on the second floor of the duke's mansion.

He went downstairs and checked the first floor of the mansion. This place was the same as the second floor. There's no sign of people living here except for the two rooms.

The duke's room and the wife's room.

Also, the children that were mentioned in the diary. Souta couldn't find them at all.
