The days moved forward steadily as I remained hidden inside the deep quiet of my mansion, focused entirely on the next stage of my preparation. I've spent the next week programing the soul and vessel to match and be compatible and even increase the demonkings already huge adapting abilities. The dense soul of Demon King Zaltraf was still hovering right above the physical vessel that I had built on the large table. They were both packed with immense power, but they were not yet connected, meaning they could not function as one single being. I sat down in my chair, closed my eyes, and began the long process of writing deep commands into both the soul and the body to ensure they would work together perfectly. Hour after hour, I carefully linked the thick energy pathways of the dense soul to the empty, resistant veins of the physical vessel. I had to make sure every single point of connection was perfectly lined up so that there would be no rejection when they finally joined together. Whenever I noticed a slight tremor or a sign of resistance between the two, I used my own power to smooth it out, changing the code of their connection until the energy flowed without any trouble. I repeated this careful process every day for seven days, watching as the compatibility between the body and the soul grew stronger with every passing hour. They began to slowly blend into one single, stable unit, matching each other's natural vibrations perfectly. While I was locking this compatibility into place, I also worked on the Demon King's natural traits. I programmed the system to increase the demon kings already huge adapting abilities, opening up deeper layers within the energy structure. I made it so that the moment the vessel faced any kind of outside threat or strange energy, the soul would instantly recognize it and alter its own structure to counter it completely. This took his original adapting traits and multiplied them significantly, making the body and soul capable of changing on the fly to survive absolutely any situation. By the end of the entire week, the programming was fully complete, leaving the soul and vessel perfectly matched and highly adaptive.
After that was completely finished, I did not take a single moment to rest because I knew my time was limited and my ultimate goal was still far away. After that I've spent the next 2 weeks making a new sword that is made from a body of a god that I killed before. I went deep into the hidden storage areas of my mansion to retrieve the heavy remains of that fallen divine being. The body of the lesser god was still heavy with an immense amount of natural power, standing as the perfect material for an unbreakable weapon. I brought the massive remains back into my workshop and prepared the heavy tools necessary to break down and reshape something that was once divine. Forging a weapon from the literal body of a god was an incredibly difficult and exhausting task that took up every single second of the next fourteen days. I had to use intense heat and my own concentrated physical strength to break down the bones and divine tissue of the god, melting the materials down into a thick, glowing liquid that shone with a bright light. I poured the glowing material into a long mold, shaping the basic form of a blade, a guard, and a hilt. The material was incredibly stubborn, resisting my hammer blows and refusing to take shape easily, but I kept striking it with everything I had. Day after day, the heavy sound of my hammer echoing through the halls of the mansion was the only sound to be heard. I spent the first week just getting the rough shape of the sword down, flattening the edges and ensuring the balance of the weapon was absolutely perfect in my hand. During the second week, I focused entirely on refining the blade, sharpening the edges until they could cut through anything, and polishing the surface until it looked like a clear mirror of solid light. The sword felt incredibly heavy, vibrating with the residual energy of the killed god, but it was now completely obedient to my grip. I worked until my hands were calloused, but by the end of those two weeks, the physical frame of the new sword was fully complete.
With the physical shape of the sword fully created, the most critical part of the process began, which required me to put complex instructions directly into the blade. I programmed the sword with the god's mana to delete the existence of anything it touches except me. I drew out the remaining, pure mana from the god's body and channeled it directly into the core of the blade, wrapping it around the sharp edges. I wrote a strict, absolute command into the weapon's energy signature: the moment this blade makes contact with any object, armor, or living being, that target will be instantly erased from reality. There would be no wounds left behind, no blood, and no dust; it would simply delete the existence of whatever it struck completely, leaving nothing behind. But I put a very specific exception into the code, programming it so that I was completely immune to this effect, ensuring that the blade would never harm its creator no matter what. After that command was locked in, I continued to layer more heavy instructions into the sword's energy system. I programmed it to resist concept manipulation, ensuring that no enemy could ever alter the fundamental idea or definition of what the sword is, meaning its purpose and state would remain entirely unchanged by outside reality-warping powers. Next, I programmed it to parry all attacks. I made it so that the moment an incoming strike, projectile, or magical force came near the blade, the sword would automatically deflect the danger away perfectly, leaving no opening for an enemy to break through my guard. To support this, I programmed it with absolute durability, making the blade completely unbreakable under any amount of physical or magical pressure, ensuring it could never chip, crack, or shatter. I also gave it increased mana density capabilities, allowing the sword to hold and compress massive amounts of energy inside its steel without bursting, making its attacks incredibly heavy and packed. I didn't stop there; I also programmed law resistance and rule resistance directly into the metal. This meant that if an enemy tried to use the natural laws of the world or specific rules of a battlefield to restrict, weaken, or stop my weapon, the sword would completely ignore those restrictions and function at full power regardless. Finally, I programmed regeneration weakening into the blade. I made it so that if anything survived a near-miss or managed to clip the blade, their ability to heal or regenerate their body would be severely slowed down and crushed, making any damage completely permanent. I spent days and nights locking these complex traits into the sword one by one, making sure they were woven perfectly into the god's mana.
When the last line of programming settled deep into the dark, shining steel, a massive wave of pressure rolled out across the entire room, forcing the air to turn cold and heavy. The weapon stopped glowing wildly, settling into a calm, terrifying stillness that showed its true completeness. This sword is now God rank. It felt lighter than a feather in my hand, yet it carried the weight of an entire world within its sharp edge. I held it up, looking at my reflection in the polished metal, feeling the absolute power radiating from the absolute durability and the various resistances I had worked so hard to build over the past two weeks. It was a weapon designed to break the unbreakable and kill the unkillable. I gripped the hilt tightly, knowing that my work in isolation had yielded the ultimate instrument of destruction. Even vaelrith can't survive this. The thought brought a cold, hard smile to my face as I stood alone in my private workshop. The sheer power of the blade combined with the perfectly matched vessel and soul of the Demon King meant that my return was no longer just a distant dream; it was an absolute certainty. I carefully slid the God-rank sword into its sheath, letting the heavy quiet return to the mansion. My preparations inside these walls were finally complete, and the tools of my vengeance were fully ready for the war ahead. I turned away from the workbench and walked out of the room, heading toward the grand exit of my home while thinking about the vast world that lay outside. now I just gotta gather some comrades. I needed to find strong allies who would stand by my side, individuals who could help me carry out the rest of my grand plan and ensure that everything went exactly as I intended when the time came to strike.
