His stern expression was different to what he showed earlier, it only meant that the case about Yu household was serious. He then ordered ȧssistant Wei to retrieve something.

Assistant Wei obliged and went to the shelf where the figurines were displayed, there was a hidden compartment on the upper part of the shelf as the ȧssistant took a box from it. He put the exquisite box infront of the silver haired young man and her students while the head patriarch left his swivel chair as he neared them. He sat in the leather chair facing Chun.

"Open it and you'll see what's inside," Yu Luo stated with a severe tone.

Chun frowned as she looked at the exquisite box, even the container had an ancient-feeling to it. There were runic symbols intricately carved at the upper part of the box, it was somehow forming into a text that the silver haired young man was familiar with.

'Ignes text.' Chun thought while recalling on the books that she had read. This text dated back from the silver age where the discovery of runes as a form of protective enchantments emerged. Ignes text was hard to decipher because the characters were from the combining runes yet it was easy for the youth to read it due to her memory when she was Pandora.

The silver haired young man pretended to be clueless to this text as she inquiringly looked at Yu Luo that made the head patriarch looked away and coughed. As a devoted artifact collector, the man had an irresistible urge to ask Chun as his model for his figurine but he immediately buried that thought away.

Chun opened the box and an antiquated cubic material was inside, it had signs and symbols on it. In the cube, there were boxes in a form of columns and every boxes there were corresponding symbols.

Lerrent who were familiar to this kind of things commented, "It's a decoder cube."

"Decoder cube? I have heard of it!" Li Li with glinting eyes looked at the object at the hand of the teacher as she wanted to grab it as well in order to examine the cube.

As you rotated it, it would correspond to another symbol and sign. Yu Luo then explained, "This is a family heirloom that would usually passed to the appointed head patriarch as a keeper of it." His words had a meaning behind it as he stared at the silver haired young man.

"The one that Yu Lee In took had to do with this, right?"

"Yes, it was supposed to be a ciphertext that should be decoded only by this Eishener Cube." As Li Li heard that, she couldn't hold anymore her glinting eyes due to amazement. She couldn't believe that the legendary cube that she would usually hear in her grandfather's story was real.

Eishener Cube was a decoder cube that only specialized at deciphering certain ancient texts. It was made by a famous forger who was interested at deciphering ancient languages that were left behind by his ancestors so he created this cube and named it as Eishener from the Lakora language which meant unveil.

"You're right, miss. This is the one and only Eishener Cube in the whole world, it was discovered by the Yu clan's ancestor during his expedition at the Grave Forest," Assistant Wei said.

"So we are going to look for Yu Lee In and retrieve the object which he took?" Chun concluded.

"Yes but there's more to it." Assistant Wei brought out a paper from his pocket and handed it to Yu Luo. The paper contained dried blood on it and what caught the silver haired young man's attention was the written message.

"This message was left behind of one of the victims of the murder. Yu Haein came from the side family branch and she died during her bath. The body was found drowning in the bathtub and there were hints of blood in her bath that came from her eyesockets due to the removed eyes. The lab results stated that her blood was used to write this," Yu Luo stated, referring to the piece of paper.

Yu Luo handed the paper to the silver haired young man as Chun said, "During the three years of murders, how many deaths in each year?"

The Yu main family had a head count of twenty person. The two side-branches were a total of two hundred and during three years, the 220 family members were reduced into 48 people. Someone could call it as a mass murder if not for the interval years and months that the murders happened. Though kids were spared, in the 48 family members left, there were around 9 kids ranging from 8-13 years old.

"There are estimated 56 deaths in each years." It was a shocking case as the culprit was able to have a death count of fifty plus every year.

Chun narrowed her eyes as an idea came into mind. The culprit wasn't working alone as they were able to execute that killing spree. And what would be the motive of the killer?

After ȧssessing the case, the silver haired young man with her group of students were led by the previous butler to a guest room. Li Li was scared of sleeping alone as she wanted to be with Lith. Chun then decided to take three guest rooms, one for the boys, one for the girls and the other room was for her alone.

Kai Sun even suggested to sleep with the teacher as he didn't want the silver haired young man to be alone on this 'murder' mansion. Cases of murders were happening here and they were now currently staying at the site.

Chun declined his offer as it would be a hassle for her because she's not a boy and sleeping with a boy in a room was not good for her. She would be bathing in her female form as the transformation potion would wear off when her body would be soaked in warm water. Commonly, Chun would only bath in lukewarm water or cold water in the penthouse but now she decided to request for a hotbath in order to loosen her tense nerves because of this case.

The silver haired young man sighed in relished after she soaked herself in a comfortable bath. The bath had a lavender oil on it added by butler for her young master to relax due to the long journey they went through and the case they would be solving for later.

While soaking in the warm water, the silver haired young man who had a stature of a boy had transformed slowly into a budding beauty. She had the exact curves for a girl in seventeen years old. Chun was humming a tune inside the bathroom while enjoying her bath, amidst to the murders that were happening on this place, it didn't frighten her as she trusted her butler. Art outside was comfortably sitting on a chair as he flipped through the pages of a book while waiting for the young master.

Specifically, it was Terra's scream.

Chun immediately washed off as she went outside, wearing a bathrobe. Art was hiding in the shadows, tailing the silver haired young man, though he forgot to warn the young master about her body because of the abrupt movement of the youth. He'd just wished that no one notice Chun's body.

Lerrent, Han, Kai Sun and Rye were already outside the room of their classmates as they heard it too. Terra was on the floor crying as Lith comforted her while Li Li was standing there in shock, staring into something.

"What happened?" Chun barged inside and the others followed as well.

"T-teacher... I saw something in the mirror at the bathroom," the crying girl stated as she saw something hideous at the mirror.

Chun frowned as she asked, "What was it?"

"A girl with no eyes s-staring straight at me."

Before Chun could say anything, Kai Sun interrupted, "Teacher, you need to look at that!"

The silver haired young man was focused on the crying scene that she didn't notice that Li Li was staring into the bloody wall.

'Who dares shall die.'

Chun narrowed her eyes as she thought something odd from this. She didn't believe in ghosts and the mastermind behind this act indicated from this message alone that he wanted them to not involve themselves on this case if they didn't want to die.

'Yes, who dared.' Chun thought as she smirked inwardly. Somehow the font of the bloody words on the wall was the same on the bloody note that Assistant Wei gave.

The silver haired young man neared the wall and took out the note from her spatial storage. She put it beside the words on the wall and compared them.

"Third young master! What happened?" Yu Luo with Assistant Wei arrived. The ȧssistant was in his sleeping wear while the head patriarch was still in the same suit.

Witnessing the bloody wall, Yu Luo wasn't surprised and stated, "That culprit usually does this to scare the visitors. Last time I remembered, a guest of mine was scared because of this act. I didn't expected that the culprit would be brave to try this on you as well."

Yu Luo shook his head as he heaved in deep sigh. It was truthfully giving him an headache. His business partners or guests that stayed here didn't want to go back anymore due to this and sometimes it dealt a blow on the family company. There clients would be fleeing as they didn't want to ȧssociate with people who lived in a 'haunted mansion'.
