Following from the day Sebastian left the duchy, Rachel felt so gloomy that she needs a diversion to avoid her loneliness. She went to the butler's office to see if she can ask Alex to give her some of his work.

Alex was surprised to find the Duchess in his office, and he realized that she must be feeling down because the Duke was away. He handed over the account books which included a list of the dukedom's costs and revenues. The account books are kept in a magic box, where all the data is preserved in its original format, to prevent manipulation.

Rachel finds the magic box so fascinating that a mana may be used to conjure up objects through magic. She then gets the bright idea to use the mana power to develop a box like a computer. Back in her previous world, Rachel majored in Industrial Engineering with a knowledge of computer coding thanks to her father, who taught her the skills when she was a young girl.

"Alex, I would like to meet the person who made this magic box". Rachel can't suppress her excitement to meet the genius behind this creation.

"Your majesty, the inventor of this device is a young genius, a prodigy of Lord Aldworf, the master of the wizard tower".

"Can you please help me to meet him? I would like to discuss something about this magic box".

Rachel pleaded excitedly that Alex accompanied her to visit the tower located at the rear area of the palace.

'When the Duchess had a fresh idea, her mood improved and her eyes once again sparkled' Alex observed, and he decided to accompany her to lessen the Duchess' loneliness.

When they arrived at the wizard tower, she is so amazed by the architecture inside. There are wizards working on different departments and there's a spiral stair that connects to all the areas. This is where all the major developments in the northern empire are created. Rachel thought that this is like the Silicon Valley of her world.

Master Aldworf welcomed Rachel and guided her to the room where his prodigy is working. "Suhin, her Majesty is here to speak with you". Aldworf commanded Suhin to pay respect to the Duchess of Astrid.

"I greet her Majesty, the mother of the north". He then made a ceremonial bow.

Rachel looks at the young genius, his features look different from the Kratoryahn's. In her previous world, his face resembles more from the eastern hemisphere.

"If you wonder why he look different, your Majesty, because this child came from the East. He was a slave trade victim that I rescued". Aldworf explained with a warmth on his tone.

"Please rise and be comfortable. I would like to ask you a few questions if you don't mind". Rachel can't hide the excitement in her face.

Suhin felt embarrassed when he saw the Duchess since it was the first time, he had ever seen someone so beautiful and yet so humble. She doesn't mind interacting with a slave and being in a cluttered room.

"Then I will give my best to assist her Majesty". Suhin trembled slightly and can't contain a flushed on his face.

'Oh, my he seemed embarrassed, why his cute!'. Rachel smiled warmly and began to scan the room. There are numerous gadgets and mana stones scattered over the area. The computation of his inventions was written on a board. She went there and looked over the details.

"Could you explain how you arrived at this calculation?"

"To answer your majesty, this is a basic computation to extract mana and put it in a tool to create an object of your desire". Suhin shyly explained and is curious why the Duchess is fascinated to such complex ideas.

"Fascinating! We can add more and make something out of this computation. Rachel concluded before moving on.

"Now can you tell me; do you have the computation for the ledger magic box you have invented".

Suhin pulled out the document and handed it to the butler.

(Excerpt: It is forbidden for lower ranks to give something directly to the higher/highest ranking noble in the empire.)

Rachel checks the document and review the computation. She then went to the board and write something out of ordinary. She writes the binary codes according to the alphabet and numerical data she read from Suhin's document. Then she extracts the basic formula of mana and combine it with the updated version of binary codes she just solved. Suhin saw what she did and add another formula to complete the binary code structure.

Rachel thinks that this world has more technological advancements in terms of resources because they have unlimited magic called mana. The mana stones generate magic and energy that can be used to make any type of device. What they actually need is a mathematical formula to develop a technology that will benefit their civilization.

Suhin beholds the Duchess with admiration and respect, much like a student would a teacher. He actually spent how many years looking for this equation, but the Duchess found it in a heartbeat.

The other wizard students watched in admiration as they saw the two geniuses work together. They were about to approach the room where the Duchess was when Sir William and the two elite shadow guards blocked their path.

Alex and Aldworf were in awe of what just happened. They look at each other and concluded that their Duchess is the prodigy genius of this empire equal to Suhin.

'Hah now you think I'm a super genius like Suhin but this code is already available in my previous world, I just copied it'. Rachel giggled inside.

"Excellent! Now I need a paper to draw something so we can input it into the device". The people around the room scattered to find a piece of paper. The butler received the drawing paper that Suhin had given him, and there is excitement visible in his eyes.

Rachel illustrates a computer with a flat screen and keyboard. She filled in the entire alphabet and all of the digits on the keyboard drawing. She wonders if they can create a flat screen and keyboard using a magic glass powered by mana.

Suhin's mouth dropped as he at last understood the meaning behind her drawing. The Duchess wanted to design a box that could hold thousands of pieces of information. Being able to access it at any moment will boost productivity for each task.

"Your Majesty, I..I..I. am grateful for your wisdom and kindness in giving us access to this knowledge so that we can advance our empire." Suhin knelt down and made a respectful bow.

"Be at ease. This will not be possible without your final code structure. Now, I want you to create this design using a glass powered by mana and connect the flat screen to the rectangular board". In response Suhin ask his assistant to find a magic glass so they can complete the Duchess order.

"I'll come back and then see if it works". The people in the room were in a daze as they tried to recover their breath after seeing the Duchess smiling so brightly.

Rachel finds another purpose to spend her time wisely while waiting for Sebastian to return.
