(POV-Shin)
We decided to stay at the royal castle after Meltrine's parents' persuasion. We planned to go back instead but the girls also insisted. I accepted since we are in vacation anyways.
"Onii-chan, what are you going to do?"(Shira)
"Well, I'll experiment and test various things."(Shin)
She, Takeru, and Athena decided to follow me. I decided to cast the space magic forbidden level spell, [Another World(Create Subspace)].
"So it could really recreate what I have imagined..."(Shin)
I imagined our mansion's garden and it really was recreated. The [Personal Subspace Creation] unique skill can also do such thing but it can also enchant this space so it will remain permanent and cannot be peaked and could be hidden from god's perception.
"This is amazing. I can't get divine revelation outside this place."(Athena)
"So you can still get one in here huh."(Takeru)
He looked at her with exasperation. Shira sighed.
"Takeru, you don't get it? That means this world have its own astral planes, astral veins, and akashic records."(Shira)
I nodded while thinking the same thing as her.
"!!!!"(Takeru)
"What an absurd ability rivalling an authority."(Athena)
She sighed in admiration. We experiment on our own after I expanded the subspace.
"Shin, you have the seven magic books of downgraded version of concept level magic attributes right?"(Takeru)
"Right. I almost forgot."(Shin)
I printed one for them. I decided to check out Space Magic first. [Teleport][Aport][Return][Telephone][Clairvoyance][Teleport Any Object][Aport Any Object][Telephone][World Phone(Infinite Telephone)][Isolation Wall(Deracinator Jail)][Maze(Labyrinth)][City Guard(City Wall)][Space Slash][Space Smasher][Dimensional Slasher][Sacred Dimensional Slasher][Space Disintegrate][Dimensional Blade][Sacred Dimensional Blade][Another World(Create Subspace)]. I start registering it all in unique skill [Menu]'s Magic Tab. This unique skill is way too convenient...
"...[Disintegrate]."(Shin)
I created this spell out of joke but it was way too strong...
-[Destruction Magic LV 10] Skill Acquired-
[Tactics Talk][Distant Sight][Clair Hearing][Senrigan(Extra Clairvoyance)][Dimension Smasher][Country Guard][Continental Guard][Planet Guard][Super Isolation Wall(Hyper Deracinator Jail)][Magic Attack Reflect][Physical Attack Reflect]. I registered those too. I keep registering the spells and my original spells.
-[Magic Knowledge] Skill Acquired-
-[Master Wizard] Unique Skill Acquired-
After activating the unique skill, I saw the lists of spells of the attributes I don't even have. Like [Destruction Magic][Explosion Magic][Musical Magic][Construction Magic][Blacksmith Magic][Alchemy Magic][Prayer Magic] etc. along with the spell. Takeru said that they are lost skills.
"Let's get serious."(Shin)
[Engrave Magic Formation][Memory Peeker][memory Reader][Soul Intrude][Psycho Dive][Mass Domination Psychology][Honesty][Lie Detection][Truth Speaker][Air Purification][Mass Fire Extinguish][Dyspnea][Suffocation][Area Silence][Copy Memories][Air Purification][Light Virus Purification][Terraform][Youth Regeneration][Human Body Transmutation][Fly][White Inferno][Water Cleaner][Water Purification][Cultivation][Radiation Cleanser][Ozonation][Gravity Adjustment][Neutral Magic Area][Dispel][Magic Delete][Mana Usurp][Wood to Amber][Sand to Glass][Radiation Shield][Radiation Barrier][Anti Magic Area][Complete Medical Exam(Full Check Up)][IED(Improvise Emergency Defibrillator)][MRI(Magnetic Resonance Imaging)][Ultrasound Scan][X-ray Exam][ECG(Electro Cardio Gram)][Full Body Scanning]
"...[Create Philosopher Stone(Sacred Tree Stone Creation)]"(Shin)
The amber on my hands become philosopher stone.
"You actually created it..."(Athena)
"Indeed..."(Takeru)
The two have exasperated faces.
"So philosopher stone is not a stone but a gem. That is a new discovery."(Shira)
"I hypothesized that it produced from sap that crystallized mana filled gem. The continuous input of ether to mana converted and pumped to the core is the cause."(Shin)
"So by replicating the process, you created one. You substituted amber as gem, transformed it to become hyperconductive to magic power and mana then input ridiculous amount of mana into it without spilling out until the threshold is achieved. How did you found out the threshold limit ratio then?"(Athena)
"That's easy. All onii-chan have to do is to drain the philosopher stones with magic power and mana. Then calculate the weight of left stone and the amount of mana and magic power drained. Then create at formula to find the perfect ratio. There are magic power wavelengths to consider but well, he won't overlook that."(Shira)
I nodded in affirmation. The two looked at us like we are unidentified lifeforms.
"Takeru, seriously. What's with these siblings? Or are we the ones abnormal not thinking what they did?"(Athena)
"No, no. Athena-dono's common sense is correct. They are strange ones. Even I never thought about that"(Takeru)
They sighed in exhaustion.
"I need more magic power. Let's see..."(Shin)
I created more spells. [Nuclear Fusion][Nuclear Fission][God's Particle][Imaginary Bomb(Black Hole)][Demolish Yoke(Graviton Bomb)][Neutron Wave Explosion][Quake Sky(Space Quake)][Dark Matter Explosion][Anti Matter Explosion][Genesis Buster(Anti Matter Cannon)][Create Clone][Copy Clone][Growth][Construct Infrastructure][Instant Harvest(Fast Floral Growth)][Nourishment Supply][Supernova][Create Floating Chessboard(Create Battle Space)][Create {Chemical Element}][Sky Net Defence (World Observation System)][Gem Art][Glass Art][Stone to Salt][Inorganic to Salt][All to Salt][Absolute Zero][Origin Flame(Flame of Genesis)][Flame Sky(Flame Heaven)][Flame Hell(True Inferno)][Flame World(World Conflagration)][Megiddo(Flame Apocalypse)][Origin Light(Light of Genesis)][Armageddon(Light of Apocalypse)][Dimension Prison][Spatial Prison][Mind Connection][Fat Burner][Fat Reduction][Dreamland Connection][Nightmare Connection][Horror Land Connection][Halloween Land Connection][Dimensional Vision][Spatial Vision][Frost Sky(Freezing Heaven)][Ice Age(Freezing World)][Cocytus(Freezing Hell)][Ragnarok(Freezing Apocalypse)][End of Vermillion(Flame End)][Autic Shield(Psychic Shield)][Miasma Shield]
"...[Create Mana Crystal]."(Shin)
I used 90 percent of my magic power.
"... Umu. It has blue crystal glow."(Shin)
I drain its magic power.
"Sphere is quite unsophisticated... [Transmute]. 10cmx10cmx10cm cube is more eye pleasing."(Shin)
"... Onii-chan... What the hell are you doing..."(Shira)
"Fufufu... Just look~"(Shin)
I take out the liquid circuit A, B, C. A for high conduction, B for strength and durability, C for large conduction. I mixed it to 10:85:5. The I engraved the magic formation that is so complicated and let the liquid circuit flow and settle down. I also put enchantments to ensure its not to disintegrate. i slowly pour some magic power to it.
"What in the damnations have you done?!!!"(Athena)
"Mana Reactor. Now, I have infinite mana to spend."(Shin)
The three groaned.
"Onii... I want one."(Shira)
[Me too!!!](2)
I created one for them too. The girls learned about it so I created one for them too.
