Getting to work 3

[Reward: Infinity Castle Demon Art (Kimetsu no Yaiba)]

I was shocked, unable to understand why I received the Infinity Castle Demon Art. It didn't seem to have anything to do with technology or science. Confused, I decided to ask the source.

"System, why did I get the Infinity Castle Demon Art from Kimetsu no Yaiba?"

If what I was thinking turned out to be true, this could be a game changer. The system confirmed my suspicions.

[Explanation: The Infinity Castle Demon Art, used by Muzan Kibutsuji, served as his lab to conduct scientific experiments. Since Muzan's powers were also derived from science, the system has concluded that Demon Arts are enhancements tied to the tech system.]

So, I was right. As far as I know, Muzan's powers aren't mystical. He gained his abilities from the Blue Spider Lily, given to him by a doctor as a medical treatment to cure his illness. Since the medicine itself is a product of science, this opens up a lot of possible powers I can acquire while eliminating others, like Chakra from Naruto or the Saiyan bloodline from Dragon Ball. But hey, you win some, you lose some.

Ding!

A notification sound came from my phone. When I checked, a smile spread across my face—I could see $10 million distributed across my different bank accounts.

I'll check out the Infinity Castle tomorrow. For now, I should head to sleep.

[ Tomorrow]

After waking up, I brushed my teeth and took a warm bath. Hot water > cold water.

I looked at my body in the mirror, feeling a bit dissatisfied. I'd need to work this body to the bone if I wanted to achieve the physical strength and agility of someone like Spider-Man.

"Good morning," I greeted my mother, who was busy cooking breakfast. She looked surprised.

"You're up early," she said, raising an eyebrow.

"Yeah, I was planning to go outside the city for a while," I replied casually.

"Are you sure you want to leave the city with your injury? You'll be fine, right?" she asked, concern evident in her voice.

"Yes, Mother, I'll be fine. If a brick didn't kill me, nothing else will," I replied with a small smile, though in the back of my mind, I knew there were far more dangerous things in this world than a brick.

"Okay, but make sure to call me, alright?" she said, concern still evident in her voice.

"Okay, Mom. You don't need to worry so much. I'm just going to Star City. That place is so empty of crime that Green Arrow has to go to another city to catch criminals," I said with a hint of sarcasm in my tone.

[few minutes after]

I looked at my social points counter and saw that it had grown while I was asleep. It now hovered at 320. Not a lot, but just enough for a silver-tier pull. The question was—should I use it? I could save the points, but earning more in the future would be easy with the plans I had already set in motion.

Without wasting another moment, I clicked the yes button.

[Reward: Joker Outfit (Persona 5)]

In front of me appeared the description: A long black trench coat with a striking crimson interior lining, paired with sleek black pants and a high-collared gray shirt. Polished black shoes and a white masquerade mask, accented with sharp black markings, complete the ensemble.

I stared at the outfit, impressed.

I quickly summoned the outfit and began wearing it. It fit me perfectly, as if it had been tailored just for me

Standing inside the Infinity Castle, I took a moment to explore and understand how it worked. Its vast, shifting corridors and isolated nature made it the perfect base of operations. Only I had access to it, a significant advantage in a world teeming with dangers.

However, I decided to keep the existence of the castle a closely guarded secret. In a world like DC, where geniuses such as Tim Drake and Mr. Terrific can create multiverse travel systems in a day, what's stopping them from designing a dimensional travel system to locate my base? The chances are slim but not zero.

This world has thousands of brilliant minds, and I need to tread carefully if my plans are to succeed. One wrong move, and it could all come crashing down.

Once outside, the castle door closed behind me. Yeah, I can design different types of doors—it didn't always have to be a traditional Japanese-style sliding door to work. With that done, I started heading toward the airport to catch my flight to Star City, the home of Green Arrow and his sidekicks, Speedy and Artemis, if I remembered correctly.

I had chosen Star City for several reasons. First, there were few to no metahuman superheroes active there. Second, the crime rate was comparatively low. Third, and most importantly, Green Arrow wasn't as smart as Batman, as strong as Superman, or as fast as the Flash. This made it an ideal location to establish my second base of operations.

It was also the perfect place to begin laying the groundwork for Stark Industries. The city was a launchpad for my plans.
