?Having the materials for the katana in my hands, I went straight to the workshop. My sister''s sword must be made of high quality materials. But my sister is still with me.


    "Why are you still following me?"


    "I want to see you work."


    "Then, it''s not a surprise anymore."


    "I don''t care."


    My sister followed me until the workshop. Maybe she wanted to witness the process of her future sword. I don''t mind her watching me, as long as she doesn''t disturb me.


    "Just don''t touch anything here without permission, okay?" I reminded her after opening the door.


    "Okay." she nodded and we entered the workshop.


    After entering the room, I locked the door and begin to prepare the solution for the time schedule.


    The workshop was located on the third floor of our mansion. The second floor was only limited to a few servants so disturbance was not a problem. The inside was filled with equipments and tools for my inventions. The walls had soundproofing and anti-surveince functions for secrecy and confidentiality.


    "Barrier."


    I casted a Level 4 Pure Magic spell to erect a barrier that enveloped the whole workshop. Enhanced it with my Level 8 Infinite Barrier Maniption spell, I can freely shaped it ording to my will.


    "Time el."


    I casted another magic spell again. But this time, it was a Space-Time Magic spell, Level 8 Time Dy. It was a spell that elerate the flow of time. I only casted it to the area of my barrier, so it doesn''t affect the whole world.


    The eleration rate limit was proportional to the user''s magic power. Currently, I can freely change the time in my barrier up to nine times faster than real world.


    "Hey, Raphael. What did you did just now."


    "I just elerated the time flowing of this room."


    "Really? Its feel like nothing." she tilted her head in confusion.


    "Sigh… Try shooting a spell from the window and see."


    "Okay…"


    After hearing my words, she approached towards the window and opened it.


    "Water Bullet!"


    She casted a valley of low level Water Magic and shoot it out of the window. The bullets flies at normal speed inside the room. But when it passed the window, which was the boundary of my barrier, it suddenly flew slowly like the flying bullets in a scene of The Matrix.


    "Whoa. It really move slowly. Now that I think about it, the swaying of the leaves seems slow. As if the whole whole was suspended."


    "No. This room was just moving faster than the world. Nine minutes here is only a minute in the real world." I said debunking my sister''s statement.


    "Is that so?"


    She closed the window back and I opened my Inventory to take out the materials needed for the katana.


    "Now, let''s get started."


    I put my personal protective equipment and lit the forge. I grabbed ingot that I will be using for the material of the de, an adamantite ingot.


    I will use this metal for the de instead of orichalcum or mithrill. Mithrill had high mana conductivity but not durable enough for my sister''s usage.


    Orichalcum was more durable and only a rank inferior to mithrill in terms of conductivity but it was too conspicuous. It gave off a dazzling golden gleam and attracts to much attention.


    Adamantite on the other hand, was more durable than the orichalcum. However, it had a mana conductivity lower or almost equal to orichalcum but much higher than the silver.


    Its metallic blue hue isn''t too lustrous and more like a blue tinted steel. Sister''s main attribute is Lightning like Mother. Lightning Magic ispatible to any type of steel materials. It''s definitely worth it for my sister''s de.


    I molded the ingot and shaped it based on the 3D object I''ve been constructing in my mind. The material is adamantite, the hardest know material to mankind. The harder the material, the more difficult and moreplex for it to mold with Alchemy.


    I pour huge amount of mana to the ingot and sessfully shaped it into a thirty inch long deep blue rod. I put it in the furnace and chanted a spell.


    "Smelting Heat."


    It was a Level 6 Fire Magic spell that can melt hard metals. Few of the veteran cksmiths had this spell for smelting hard metals like orichalcum.


    After heating for a while, the adamantite rod made a red hot glow. I took it from the fire with the tong and ce it on the anvil. With the hammer on my right hand, I hit the hot steel and to tten it.


    "It is really difficult and time consuming if seen up closed."


    "Yeah. So don''t be too close if you don''t want your sword to deformed."


    "Yeah, yeah, I understand."


    Sister pressed her chest against my back again after I put back the hot rod to the forge. I warned her that distractions might cause deformities to the de.


    I prepare the rod again I hit it repeatedly with the hammer on the anvil. The sound of shing metals resonating the entire workshop as I keep shaping it.


    After continually hitting the hot steel, it already had the curved shape, the tang, and the back side of the de. Then used a fullering tool to draw the groove and the ridge.


    "Can you operate that machine for me?" I asked for help, pointing the said machine.


    "Not a problem. Then what should I do?"


    "Hold the handle with each of your hand and cast Short Circuit spell."


    Yellow bolts of dazzling lightning emitted from each of her hand holding its corresponding handle and the machine started to work. And that machine was my homemade sanding belt machine.


    "You never failed to impress me with your revolutionary ideas."


    "Good job, sister." I praised her while giving a thumbs up.


    "Of course. I am your sister after all."


    I adjusted the speed of the rotation right enough to grind the adamantite. Then ce the de against the running sandpaper and started to sharpen the edge side of the de.


    The machine was powered by electricity instead of magic. The spell that my sister used was a Level 3 Lightning Magic spell. It emit lightning bolts on each of the user''s hand with different charges, positive and negative charge. If the two bolts met, it short circuit and explode.


    The machine had handles that receives electrical charges to spin the motor, which made the belt to spin. It also had voltage regtor to control the voltage and a switch to adjust the rotation speed.


    (If Mother was the meat grinder, mom was the storage room, then my sister is the power generator…)


    "And the de has done."


    "Yey! As expected of my little brother!"


    After hours of hitting and shaping, minutes of sharpening the de and polishing the impurities, I am finally done with the de. Now that I''ve done with the mostplicated part, I proceed to the hilt.


    I opened my Inventory and took some orichalcum nuggets, silvery wool of C-ranked Thunder Sheep, B-ranked Spear Shark skin, and a branch of a B-ranked ck Treant.


    Using Alchemy, I shaped the orichalcum to make the de cor, the guard, and the pommel of the katana. ck Treant wood into handle.


    I want the cor, guard and pommel made of orichalcum to make itpliment with the blue de. It is also durable and had high mana conductivity that makes the sword more powerful and beautiful to the eye.


    ck Treant wood was as durable as iron and had high conductivity. It is also the main material for making the body of staves and wands for mages.


    I then one by one assembled the parts to the sword and fasten the tang and the handle with orichalcum fasteners. I am making sure that the wood covered the entire tang and no blue metal would be exposed from the hilt.


    I grabbed the wool and using Alchemy, I entwined the fibers of the wool and transform it to ace. Thunder Sheep wool had theponents of silver and make a good electrical conductor. I manually knotted the goldence to the handle and finished the hilt.


    For the scabbard, I still used the same ck Treant wood butrger. The same as before, I used Alchemy to shaped it. After shaping the scabbard, I engraved our family name on it using orichalcum.


    Attaching some details to the throat and the tip of the scabbard with orichalcum, and the scabbard is done.


    "And finally, your katana has beenpleted." I said to my sister as I sheathed the sword in its scabbard.


    "You''re the best, Raphael! And it''s only less than a hour had passed in the real world."


    "But before you can have it, let me enchant this first."


    I use my Unique Skill Bestow to enchant the katana with some skills. This is my gift for my sister''s birthday and my best masterpiece so far. So I have to power it up as I can.


    "Blood Life."


    A Ghoul''s Racial Skill that restores health and heals injuries when consumed blood. The de automatically generated just by drenching itself with blood.


    "Absolute Severance."


    Ultimate Art''s subskill that cuts almost everything and ignore defenses. However, it only have one usage every 24 hours.


    "Disguise." to hide the katana''s effects.


    "Ownership. And done. Just add your mana and the katana will be all yours." I instruct as a handed her the sword.


    "It''s so magnificent and overflowing with radiance. I can''t to wait to try it outside."


    "It had the ability to fix itself upon absorbing blood and a once a day attempt of Absolute Severance. I already concealed its effects so don''t use its effects in front of the others."


    "Got it. Then, what will be this sword called?"


    "Let me think."


    I haven''t think of its name yet. I have no sense in naming and I can''t just baptized the sword in a whim. I took a glimpse at my sister whose swinging her new sword. Then an idea came up in my mind.


    "I came up with a name." I said as I took the sword. "I hereby baptize this sword in the name of ''Raven Blue''."
