At the gates of the mansion, some guards were stationed. They opened the gates, and we entered. Saito led the way. Soon after, a maid approached us.
"May, can you call the others to come to the hall?" Saito asked. We then headed toward the mansion's grand hall and sat down on the sofas. Princess Yuri and Saito sat opposite me. After a few minutes, three more people entered the hall—each of them a girl.
One had black hair and eyes, another had brownish hair and eyes, and the last one had platinum blonde hair. Saito introduced them as his fiancées as well.
So he's engaged to four girls, huh…? Well, that's his preference.
He then introduced me as his brother. The girls' names were:
Mili – the one with black hair and eyes
Zoya – the one with platinum blonde hair
Silf – the one with brown hair and eyes
After some brief introductions, Saito showed me to my room. It was much larger than the one at the inn and quite comfortable. Then he said, "Come with me to take some quests from the guild whenever you have time. I usually go with the girls, and most people there give us death glares. So… help me out, will you?"
After that, he told me to get some rest. I wasn't tired, but I wanted to check something. I entered my mind realm, and yep—it was expanding even now. Just how much information do my past lives hold?
The realm was collecting every kind of information from my past lives, and I was taking a stroll in it. There were various books—the information had been converted into books and separated by type. Let's see…
There was potion-making, which included mana potions, healing potions, poisons, elixirs, immortality, and eternal youth potions. There were many more—strength potions, resistance boosters, elemental resistance mixtures, antidotes, sleeping draughts, and mental clarity potions.
Then there were sections on herbs, ores, tech, magic, divine knowledge, weapon forging…
Wait, what is this section?
What a jackpot...
I left the mind realm sometime later. I had created it because I was having trouble while looking into my memories. It would help a lot. But for now, I needed to make something else.
Before that, Saito came outside my room.
"Ryo, the dinner is ready. Let's go to the dining hall."
Everyone was present. We sat down, and I noticed a new guest—Princess Seyra.
The meal consisted of steak and some Japanese dishes like gyoza, miso soup, and tamagoyaki. However, the food was missing something. I was still trying to find the right spices for flavor enhancement, but I hadn't succeeded yet.
Maybe I should check other nations for rare spices.
"Ryo, are you free tomorrow?" asked Saito.
"Yes, I am."
"Then would you mind coming with me for some quests?"
"Hey, wait a minute! What about us, huh? Are you forgetting that we're a party too?" Mili complained.
"Hey, calm down. It's not like I'm ditching you guys or anything."
Then Princess Yuri suddenly asked, "By the way, Ryo… are you seeing anyone?"
"No, Princess. I'm not."
"Is that so…" she said, a bit cryptically.
I didn't get why she asked that. I was thinking of moving away from here for a while anyway.
Just then, Mili leaned in with a teasing grin. "So you're single, huh? Not bad. Should we start applying, Zoya, Silf?"
Zoya smirked. "Oh, absolutely. I heard he's strong and good-looking. What more can a girl ask for?"
Silf chuckled, brushing her hair back. "I call dibs on the first dance at the next party."
"Wait—what? Aren't you three engaged to Saito?" I asked, confused.
"Yes," Mili said sweetly. "But a little teasing won't hurt. You're kind of fun to mess with."
I sighed. "Great. I'm the new toy now, huh?"
"Don't worry," Zoya said with a wink. "We play nice… most of the time."
After dinner, I returned to my room.
After returning to my room, I was thinking of something like a different dimension where no one could see me. Oh right, there is this spell. Then I created an alternate dimension and linked it to my mind realm. In the mind realm, previously, I had found something that made me curious. According to a particular section, there was a time when I had built a nation combining magic and modern technical knowledge. It had flying ship fortresses, flying castles, robots, and other things. I was planning on improving them, but first things first—I need farms too.
Let's see... crop farms. See, I am making these farms in my alternate dimension, so the season doesn't matter. I can change the season in various locations depending on what that crop or herb will need. I can even change the climate as I want or wherever I want in the dimension. This dimension has no limit because it depends on one's mana pool size—and my mana pool is expanding even now.
So, after connecting it to my mind realm, I first went to make something that would manage these crops and other farms. I had various crops and herbs in my mind, including ores—I can apparently even farm ores. Then to manage those things, let's see... how about artificial intelligence and robots?
I had used them in my past life too, so I can do it even better now. So first, I made a server and various AIs to help me. One AI would command them all, with a backup unit, robots, and drones.
First, I needed a central unit to host the AIs and manage all systems—the server core.
I imagined a large, floating crystal embedded with runes. Using mana, I shaped a chunk of glowing etherium—a magical mineral that could store vast amounts of data and energy. I used Runic Coding, a magical scripting system, to carve instructions directly into the crystal's core. These runes served the same purpose as circuits and code in a normal computer.
Then I wrapped the crystal with layers of enchanted metal that acted like insulation and protection. I also connected mana conduits—veins of energy lines that kept the server running endlessly by drawing energy from my mana pool.
Just like that, my Magical Quantum Server was born.
With the server done, I focused on creating the AIs—magical minds that could think, learn, and manage tasks.
I started by defining personalities and purposes. There was one Master AI I named Nova—she would control all other AIs. Then there were specialized AIs for agriculture, mining, construction, research, and defense.
Each AI was made by combining:
Memory Crystals (to store knowledge)
Will Cores (which I made from soul fragments and pure mana, giving them self-awareness)
Runic Patterns (which defined their behavior and logic)
I infused each core into floating glyph-based bodies made of light and code—no physical body, just glowing, intelligent orbs that could travel through the system at the speed of thought.
Next, I moved on to drones—small, flying helpers for farming, surveying, and scouting.
I crafted the frames using lightweight mythril alloy, which was strong but didn't block mana flow. I made different types:
Winged drones for long-distance travel
Hover drones for scanning and mapping
Mini farming drones with extendable tools
I used levitation runes and wind magic crystals to make them fly, and embedded mana batteries to keep them powered.
Each drone had a small AI core linked to the main server, allowing Nova to give them commands instantly.
Then came the robots—my workers and guardians.
I built the frames out of adamant alloy, using auto-forging golems that shaped the metal with precision. I made different models:
Farmbots with tools for planting, watering, and harvesting
Builder units with arms for lifting, assembling, and repairing
Guardians with energy weapons and shields for defense
I installed joint mechanisms using mana-threaded muscle fibers, which acted like artificial muscles—flexible, strong, and responsive. I added sensors made from enchanted gems, so they could see, hear, and feel.
Each robot had a small sub-AI connected to the main system, but could also work independently if needed.
Finally, I connected all of them through the Mind Realm Interface. Since the server was also linked to my mind realm, I could issue commands just by thinking.
The AIs could learn from my memories, adjust to my preferences, and evolve over time. The robots and drones responded instantly, like extensions of my own will.
The entire system became self-sustaining. Drones would scan the land, robots would build or harvest, and the AIs would monitor everything 24/7, adapting strategies and optimizing output.
After setting up the AIs, servers, drones, and robots, I realized I needed a single Control Unit—something that would oversee everything I had created and everything I would create from now on.
I imagined it like a command throne fused with a magical satellite system.
I constructed a floating tower made of obsidian-like dark crystal and enchanted mithril. At its top sat a Control Core, a fusion of a supercomputer, magical focus crystal, and thought amplifier.
The core connected directly to my mind realm, allowing me to think and issue high-level commands instantly.
I embedded dimension management runes around the base to let the control unit affect reality itself—temperature, gravity, mana flow, time dilation—everything.
This unit also synced with the main AI, Nova, to act as both a general brain and a backup mind.
And since time flows differently in this alternate dimension—much faster than the outside world—I had all the time I needed to perfect every detail.
Next came the Auto-Factories—fully automated structures designed to build robots, drones, machines, and tools without any manual input.
Before making the factories, I divided them into 10 specialized categories, each with its own focus and design:
Drone Factory – Produces all drone types using 3D magical forging and mana-infused blueprints.
Robot Factory – Builds advanced worker and guardian robots.
Construction Factory – Manufactures building components: walls, wiring, energy cores, etc.
Weaponry Factory – Designs and assembles weapons for robots or defense systems.
Armor & Parts Factory – Creates robot limbs, plating, and enchanted armor.
Vehicle Factory – Produces hover bikes, walkers, and mana-powered transport units.
Energy Core Factory – Creates power sources (mana crystals, elemental reactors).
AI Core Factory – Makes modular AI units for distribution to various systems.
Medical Factory – Produces healing bots, repair units, and recovery pods.
Logistics Factory – Manages supply chains and stores raw/finished materials.
Each factory was managed by its own AI Sub-Core and had robotic arms, forge lines, rune engravers, and teleportation pads for moving materials instantly.
With the factories up, I needed research centers to constantly improve what I was making.
I built 10 specialized Research Units, each shaped like glowing crystal towers surrounded by floating screens and mechanical arms:
Magic Engineering Lab – Fuses magical and technological knowledge.
Robotics Lab – Designs next-gen robots and upgrades.
Drone Development Hub – Innovates stealth, speed, and sensory tech for drones.
AI Evolution Center – Trains and enhances AI through simulation.
Herb & Crop Research – Studies growth rates, mutations, magical properties.
Ore Refinement Lab – Tests new ore combinations and magical alloys.
Energy Study Facility – Experiments with different mana cores and energy sources.
Defense Tech Center – Develops shields, traps, turrets, and armor.
Dimensional Science Lab – Studies the structure of the alternate dimension itself.
Bio-Magic Integration Lab – Experiments with biological materials and healing magic.
Each unit was connected to a central data cloud that stored discoveries and synchronized with the control unit.
I created 10 unique types of robots, each with a specific function and build:
FarmBot-X1 – For planting, watering, harvesting.
BuilderBot-MK2 – For construction, repair, and architecture.
GuardBot-V3 – Armed defense robot with energy blades and mana shields.
MedicBot-Aid7 – Healing-focused bot with restorative magic and nanotech.
MinerBot-DRL – For underground digging and ore harvesting.
SmithBot-Forg3 – On-site blacksmith robot for customizing gear.
ScoutBot-Zip – Fast-moving terrain mapper.
SupplyBot-RUN – Transfers goods and materials.
CodeBot-INX – Repairs systems, hacks, or reprograms rogue units.
MegaBot-TITAN – Large unit for heavy lifting or battlefield support.
Each robot was crafted in the Robot Factory with its own AI, mana core, and memory crystal. They were color-coded and ran on modular mana cells.
Drones had to be versatile. I built 10 types, each tailored for different environments and jobs:
AeroScout – High-altitude surveillance.
CropSpray Mini – Sprays herbs and crops with mana water or fertilizer.
MinerFlyer – Monitors ore fields and scans deposits.
HeatSeeker – Detects enemies or threats using thermal mana.
RepairBuzz – Fixes small mechanical issues in-flight.
NightWatch – Equipped with night vision and stealth cloaking.
TransportWing – Carries small loads across zones.
ManaTracer – Tracks mana leaks, anomalies, or unstable zones.
CommNode Drone – Extends signal for control unit over long distances.
EcoDrone – Monitors atmosphere, climate, and natural growth patterns.
Each drone could fly, hover, and even enter stealth mode. I gave them a basic AI and connected them to the drone factory for constant upgrades.
Ore farming was something I didn't even think was possible until I read about Mana Crystallization Fields.
Here's how I built it:
First, I selected a mineral-rich zone in the dimension.
I used Terraforming Magic to compress mana into layers beneath the ground, simulating natural mineral formation.
Then I placed Ore Growth Catalysts—enchanted crystals that absorb ambient mana and solidify into ores over time.
I created 10 separate ore farms, each for a different material:
Ironite
Mana Steel
Mythril
Adamant Ore
Etherium
Crystal Quartz
Shadow Ore
Flame Stone
Sky Silver
Soul Alloy
Each ore farm had MinerBots managing extraction and Auto Conveyors that moved materials to the Refinement Labs or Logistics Factory.
All these systems—factories, research labs, robots, drones, ore farms—were linked to:
The Main Server
The Master AI (Nova)
My Control Unit
My Mind Realm
After finishing the setup, I gave Nova a new set of instructions.
I ordered her to assign each unit with additional sub-AIs, so that every factory, research lab, and management center could operate more efficiently and steadily without bottlenecks. These sub-AIs would handle micro-decisions, coordinate tasks, and even adapt to new challenges in real time.
Next, I instructed Nova to establish a potion farm. Using the vast knowledge stored in my mind realm, Nova began designing a fully automated potion production system. This included farms dedicated to growing rare herbs, magical flowers, and alchemical minerals—everything needed to brew powerful potions. From there, she set up refining stations, distillation machines, and bottling lines, all run by specialized alchemical drones and potion-brewer bots.
Nova's role wasn't limited to just following orders. I told her to actively monitor the entire dimension's progress, and if necessary, make improvements by drawing on the knowledge from my memories. That way, even if I focused on something else, the dimension would keep growing, evolving, and advancing on its own.
And if you're wondering where I got the raw materials to build all this?
The answer is simple: Creation Magic.
Unlike traditional magic that manipulates existing elements, my Creation Magic allowed me to generate anything from scratch, as long as I had enough mana. Whether it was steel, crystal, machinery components, or entire mountain ranges—I could summon and shape them into existence. It was like being the god of this realm, with limitless potential.
So, every beam of metal, every drop of potion liquid, and every circuit inside a robot began from my will, and became reality through Creation Magic.
