"Welcome, Rimuru!"
JARVIS's magnetic voice rang out as the lab doors automatically opened.
As Rimuru walked into Tony's lab, a strong wave of high-tech atmosphere hit her. She couldn't help but sigh—being rich is really nice.
Someday, she would build a lab even more advanced than this!
"Why did you call me so urgently?"
Seeing the dark circles under Rimuru's eyes, Tony Stark—looking almost like an elf himself—couldn't help but feel impressed.
Was this really the Rimuru he knew?
So beautiful!
European, American, and Asian aesthetics differ greatly, but also share many similarities in certain aspects.
It had to be said, Pepper's taste was excellent. The clothes she chose suited Rimuru perfectly, highlighting all of her strengths.
Especially with her flowing blue hair, she looked incredibly cute and beautiful—like a dreamy spirit!
"This outfit suits you very well!"
Tony had originally planned to tease Rimuru, but all his sharp remarks disappeared, leaving only this sincere compliment.
"Thank you!"
Rimuru smiled warmly and naturally.
After exchanging verbal jabs with Tony Stark for so long, Rimuru had finally come to understand his true nature.
He was petty, extremely vindictive, and his words were sharp and sarcastic. He acted quickly and ruthlessly. The more you cared about something, the more he would strike at it.
The number of "female outfit stains" went from zero to countless. Once worn, the stain could never be washed away.
Rimuru shattered the jar!
However, she would never give Tony another chance to tease her again!
Tony, surprised, joked, "You're adapting pretty slowly. Maybe you always dreamed of wearing women's clothes. Looks like I helped you quite a bit."
Rimuru was unfazed, impervious to both sword and flame. "Yes, Tony, do you want to try it too? Then you'll discover a whole new world opening up for you!"
Ugh!
Just imagining himself in women's clothes gave Tony a chill, completely deflating him.
"I've finished researching that healing medicine you gave me. I've extracted a self-healing factor from it that can significantly accelerate wound recovery."
Rimuru widened her eyes in disbelief. How long had it even been?
Seeing Rimuru's surprised expression, Tony suddenly felt a sense of accomplishment like never before, and happily sipped his champagne.
So satisfying!
"The effectiveness of this medicine is less than one percent of your healing potion. It's basically a heavily weakened version, but it's enough as a first product."
"I've named it 'The Goddess of Life's Comfort.' It will be commercialized by Stark Industries' biotech division, with shares distributed according to our previous agreement."
"In other words, Rimuru, before long, you'll become one of the richest people in the world!"
Rimuru excitedly rubbed her hands together. Making money while lying in bed without working—it felt amazing!
Cheers!
Tony popped a bottle of his prized champagne, and the lab was filled with a joyful atmosphere.
For a moment, Rimuru and Tony were surprisingly in sync, getting along well, while their usual teasing rivalry turned into something closer to camaraderie.
"Tony, let's make up—no more hurting each other from now on!"
"What disagreement? I don't remember any."
"You're right, there was never any bad blood between us!"
"To friendship, to the future, and to… whatever!"
Although Tony Stark had somewhat questionable taste, his genius-level intellect was undeniable.
With Rimuru's involvement, the development of the Mark II armor progressed far faster than expected.
This was only natural.
The most difficult part of the Iron Man suit was actually its power source. The Arc Reactor solved that problem perfectly.
The Mark I had already established a rough core framework, and Mark II was built upon it.
However, improvement was not easy. Even something like a modern keyboard still follows design principles established decades ago.
Flight systems, shock absorption, communication systems, fire control systems, temperature regulation systems—
Each system involved one or more areas of specialized knowledge.
For a comprehensive research organization, dozens of experts might be required to complete such work.
Yet Tony Stark did it all alone. He was one of the greatest "geniuses" in the Marvel universe, though his knowledge was not all-encompassing.
Just as Rimuru admired Tony's ingenuity, Tony was equally shocked by Rimuru's knowledge and intellect.
Rimuru was able to keep up with his pace, which both surprised and delighted him. It felt like a master swordsman meeting a worthy rival, or a musical genius finding a soulmate.
That sense of satisfaction when meeting a worthy opponent was something Tony had never experienced before.
"Rimuru, this lab is yours too. How about we each improve things and compete to see who does better?"
Rimuru raised an eyebrow. She was about to remind Tony about the icing problem when he unexpectedly proposed a competition.
He asked for it—so she wouldn't hold back!
"Deal, Tony. This time I'm going to beat you completely!"
"What? Rimuru, are you sure you're talking to the great Tony Stark? Don't cry when you lose!"
"Hah, I don't think you even know how to spell 'defeat.' I'll teach you!"
What is racing?
A real man should drive a giant mecha!
Thinking about racing Tony Stark in the air made Rimuru's blood boil with excitement.
Mecha is a man's romance!
In a way, the Mark series was already a very complete design, with later versions mostly being refinements.
Many later Mark models were even designed for special combat environments.
The biggest flaw of the Mark series was that it was not easy to put on and required mechanical arms to assist in wearing and removal.
After intense battles, parts could deform and become difficult to detach.
Another major issue was that the Mark II had not solved the high-altitude icing problem.
But Rimuru was standing on the shoulders of a giant.
By following Tony's path, she felt like she could push him into a corner and leave him nowhere to go.
Tony defeats Model 2, Rimuru defeats Model 3, Tony defeats Model 4, Rimuru defeats Model 7…
She wondered if Tony would eventually suffer a mental breakdown from the shock.
Thinking about it made Rimuru laugh.
Tony Stark, are you ready to face Rimuru-sama's ruthless domination?
