Chapter 3: Operation: Rebirth (Rewritten)

Walking through the hallway, Shiro saw something he didn't expect.

"This looks more like a facility than just an underground laboratory," Shiro thought to himself.

The hallway was lined with numerous laboratory rooms, and Shiro couldn't help but wonder if Dr. Alex truly owned this place or if it had been an old base belonging to some organization.

"You might be wondering how I came to possess such a large underground facility," Dr. Alex said, understanding Shiro's curiosity as he glanced around.

"Yeah, I'm curious if you actually own this place or if it was previously owned by an organization," Shiro replied.

"Technically, I do own this place since I purchased the land, but I didn't build this underground facility," Dr. Alex explained.

"Considering the size of this facility, it's unlikely that it was owned by a single person. I'm guessing it belonged to some organization you might already be aware of. What's the name of that organization?" Shiro asked.

"Yes, it was owned by an organization called Hydra," Dr. Alex answered with an angry expression as he mentioned the name.

Observing Dr. Alex's reaction, Shiro speculated that he had some history with Hydra.

'Hydra,' Shiro muttered to himself, trying to recall where and when he had heard that name before.

'That's the infamous villain organization within the Marvel Universe,' Shiro realized.

"Never heard of it, right?" Dr. Alex asked, noticing Shiro's confused expression.

'Actually, I'm quite familiar with it, but I need more information, so I'll pretend I don't know,' Shiro thought, looking at Dr. Alex with a serious expression.

"Yes, I suppose they must be an organization with nefarious intentions," Shiro replied, feigning ignorance.

"I'll provide you with all the information about them after we finish this experiment," Dr. Alex assured him.

After a couple of minutes, they finally reached a room. As Shiro entered, the first thing he noticed was the Vita Radiation, a key instrument used in perfecting the Super Soldier Serum, famously seen in the Captain America: The First Avenger movie.

"With that equipment, I can now confirm with 99% certainty that I'm in the MCU," Shiro thought to himself.

"We have arrived," Dr. Alex announced.

"So, are you going to start the experiment now?" Shiro asked eagerly.

Dr. Alex smiled at Shiro's calm demeanor. "Yes," he replied.

"You seem remarkably composed, Shiro," Dr. Alex commented as he began removing the straps from Shiro's hands and legs.

"Well, I'm quite curious about the results of the experiment, and I'm confident that I'll survive. Also, aren't you afraid that I might do something to you once these straps are removed?" Shiro replied.

"Actually, no. I believe you're genuinely interested in this experiment and I know you will survive," Dr. Alex said, smiling.

As the straps were released, Shiro walked towards the Vita Radiation with a sense of familiarity, surprising Dr. Alex. He hadn't mentioned anything about the Vita Radiation to Shiro.

"Shiro, do you recognize this instrument?" Dr. Alex asked.

"Yes, it's called Vita Radiation," Shiro answered, gazing at the chamber.

"How do you know about it and where did you get the information?" Dr. Alex inquired, growing slightly nervous.

"Oh, umm... I did some prior research, and I have an exceptional analytical capability in my brain," Shiro responded, pointing to his head with a hint of sweat on his face.

'Well, what I said wasn't a lie, but I also used it as a cover for my transmigration here or the fact that I'm not from this world,' Shiro thought to himself.

"I see. Well, now that everything is prepared, you can enter the chamber," Dr. Alex replied.

Shiro stepped into the chamber and lay down. He was secured with straps across his chest, and various machine apparatus surrounded him. He also noticed three test tubes filled with serum. As soon as he took his place, the machines began moving, injecting the serum into his muscles. He immediately felt a slight pain, which he knew would soon escalate into unimaginable agony.

[Warning: Unknown substances are entering the host's body]

'A.I. Chip, assist me with the process and name it "Operation: Rebirth," just as Abraham Erskine called it,' Shiro mentally commanded.

[Roger]

Dr. Alex lowered the switch in the control room, initiating the process of rebirth.

The Vita Radiation closed around Shiro, and he prayed silently, hoping for a successful operation and no regrets about his decision.

[Operation: Rebirth Starting]

[▇]

[Every fiber of the host's muscles is reconstructing]

'Ugh... I can feel my muscles tearing apart!' Shiro thought, enduring the increasing pain.

[▇▇]

Dr. Alex pressed another button.

[▇▇▇]

'Agghh... I knew it would be painful, but I didn't expect it to hurt this much.'

[▇▇▇▇]

"Fuck my life... Aaagghh!" Shiro hissed, the pain intensifying with each passing moment.

[▇▇▇▇▇]

"Fuck you, Alex! Aarrgghh!" Shiro began cursing as he felt tortured.

[▇▇▇▇▇▇]

'This pain is excruciating. How the hell did skinny Steve Rogers endure this?'

[Unknown virus detected]

Shiro couldn't fully comprehend what the A.I. Chip was saying amidst the unbearable pain.

[▇▇▇▇▇▇▇]

[Every cell structure of the host's body is beginning to reconstruct. The unknown virus was not completely eliminated, but the host's white blood cells and strong willpower helped neutralize its effects on the host's consciousness.]

[A.I. Chip is undergoing an upgrade...]

[A.I. Chip upgrade complete.]

'Shiro could hear someone speaking, but the pain made it difficult to understand the words.'

[▇▇▇▇▇▇▇▇]

"Fuck Nagato and his lame-ass pain. This feels more agonizing than his backstory," Shiro muttered.

"AHHHHHHHHHHHHH!" Shiro screamed, pushing through the last of his struggles.

[▇▇▇▇▇▇▇▇▇]

'Finally, I can feel it. The experiment is almost done.'

'The pain began to subside.'

"Ha... haaa..." Shiro panted heavily, trying to catch his breath.

'I can sense that my body has become stronger, as if I've attained godlike abilities or something.'

[▇▇▇▇▇▇▇▇▇▇]

[Process Completed]

[Project: Operation Rebirth Successful]

The chamber's doors began to open, revealing Shiro inside. He took a moment to catch his breath before Dr. Alex approached him, a wide grin on his face.

"Do you hear me, Shiro?!" Dr. Alex exclaimed.

"Yes, I hear you loud and clear, Dr. Alex," Shiro replied, smiling at the successful outcome.

"Yes!!"

"You actually remembered me! WAHAHAHA!" Dr. Alex laughed genuinely.

"Of course I do. So, the potential negative effects caused by the virus can affect one's consciousness?" Shiro asked, slowly stepping out of the chamber. He noticed the changes in his body—his muscles had gained mass, and he looked more like Captain America. Not only that, but he also felt healthier than ever before.

"Yes, it can alter a person's personality, potentially in a negative way, and they may even lose all their memories. Technically, the virus I developed is infectious, meaning that if your brain had been affected, you would have started spreading it once the experiment was completed. However, I made sure it would not be infectious this time. I transformed it into more of a serum by integrating it with the Super Soldier Serum," Dr. Alex explained.

"That's quite scary. So, what is this virus called?" Shiro asked, his curiosity piqued, wondering if it was related to the Blacklight Virus from the game Prototype.

"It's called the Blacklight Virus," Dr. Alex confirmed.

Shiro was shocked, and a wide smile spread across his face as he realized the implications of the Blacklight Virus.

"No freaking way!" Shiro thought, fully aware of the incredible powers associated with the virus.

"Could you tell me about the capabilities of this serum you created using the Blacklight Virus? Can you teach me about its powers?" Shiro eagerly inquired.

"Of course, I'd be happy to demonstrate the results of my experiment. But before that, let's head to the training area," Dr. Alex replied.
