Right now, setting aside whether the key to the original formula can be deciphered, just finding a scientist capable of independently developing the Super Soldier Serum is a huge problem!
Aside from the deceased Howard Stark, Bruce Banner is constantly under S.H.I.E.L.D.'s highest level of surveillance.
It's almost impossible to take him away quietly.
The situations with Arnim Zola and Wilfred Nagel are similar.
The former is currently stored as a giant computer in a secret S.H.I.E.L.D. facility in New Jersey.
The latter is hiding in some secret Hydra Base, diligently researching an improved version of the Super Soldier Serum.
So... none of these three people can be easily obtained.
"It seems we can only plan for the long term!"
Although Karl felt somewhat unwilling, he understood that some things cannot be rushed, so he didn't dwell on it further.
After all, genius scientists who can make achievements in multiple fields are almost all rare finds.
And Karl's goal is very clear.
He will absolutely not use a sub-grade serum for enhancement until the very last moment when he has no other choice.
Because the opportunity might only come once.
No one can guarantee whether the same person will still experience an effect when injected with the Super Soldier Serum a second time?!
So Karl naturally wanted to get it right in one go.
If he's going to use it, he'll use the best.
Besides, who would use those flawed products when there's a perfect serum available?
If it were given to you, would you use it?!
However... it's said that the perfect serum seems to have a side effect of extremely magnifying the user's "personality."
That is, "making the good better, and the bad worse"!
Karl wasn't sure which type he would belong to...
Just then, a woman's voice vaguely came from the phone.
The other party seemed to be calling Pietro to get her a bath towel.
So Karl took the opportunity to ask, "I heard you're in a relationship?"
Pietro scratched his head a bit sheepishly, "That's right, I just hadn't had a chance to tell you, Natalie and I are already planning to get engaged."
Even through the phone, Karl could hear the happiness in his words.
However, I've only been gone for a few days!
And you, a single dog, have already found true love?
Isn't that a bit too fast?
No, something is off!
Pietro, that big fool, was most likely ensnared by a gold digger.
"Congratulations on finding someone."
Karl said calmly, "It just so happens I haven't eaten since I got back, why don't you bring your girlfriend and we can have a meal together?"
"And regarding the Super Soldier Serum, I'd like to understand more about it in detail."
"Okay."
Pietro agreed immediately without thinking.
...
A dozen minutes later, Karl arrived alone at Sokovia's most luxurious restaurant.
As soon as he walked into the VIP private room, he saw a woman with reddish-brown wavy hair, a hot figure, and a charming appearance, clinging to Pietro's arm and acting spoiled.
Her proud chest was squeezed into two irregular shapes.
Pietro, who had been single for over twenty years, how could he resist such temptation?
Even his good brother was already poised for action in his pants.
He himself was like a big fool, nodding and grinning foolishly.
Even if the other party wanted to take his kidney right now, he'd probably willingly offer it up!
And without anesthesia.
"It really is you, Black Widow!!!"
Karl's pupils narrowed, and he recognized the woman's true identity at a glance.
That's right, it was S.H.I.E.L.D. Agent Natasha Romanoff.
But it made sense.
He had been clashing with Hydra for so long, posting videos and trending on hot searches.
Given Nick Fury's meddlesome nature, there was no reason for him not to send someone to investigate.
And the most capable infiltration Agent he had was probably only Black Widow.
But if you're going to infiltrate, why play with Pietro's feelings, that naive kid?
Look at how utterly infatuated he is...
"Karl, you're here."
Pietro finally saw Karl's figure and quickly stood up to introduce, "Let me introduce you, this is my girlfriend, Natalie Rushman..."
However, before he could finish, Black Widow pouted her sexy lips and interrupted, "What girlfriend? I'm clearly your fiancée!"
Then she winked at Karl with seductive eyes, feigning the look of a fangirl, exclaiming with admiration, "Wow, I can't believe I actually met the great hero who liberated Sokovia."
What the heck?
The alarm is going to sound!
Widow, do you really have to be so seductive?!
No wonder Pietro was completely infatuated in just a few days, obeying her every word.
Which pure young man could withstand such a test!!!
But for Karl, who was experienced in such matters, these tricks were long commonplace.
Any reaction from his good brother would be an insult to his countless experiences with women!
"Yes, yes, yes, whatever you say, darling, is right."
Pietro once again entered his foolish mode, grinning incessantly, with saliva nearly dripping several times, which made Karl feel nauseous.
However, he was not in a hurry to expose her.
Instead, he decided to first use his Mind Perception ability to check her memories and, while he was at it, enjoy Widow's acting.
So he sat down, ate, and chatted idly.
After Pietro reported on the Super Soldier Serum, he took Widow's hand and said affectionately, "Karl, although Natalie and I have only known each other for 2 days, 13 hours, 17 minutes, and 33 seconds, I am absolutely certain that she is the woman I love most in this life."
During this, he didn't forget to check his watch, just to be able to be precise down to the second.
"We've already discussed it, we're holding the wedding in a month, I hope you can help me inform Wanda in advance..."
No... Brother, you're really brave!!!
You're actually thinking of marrying Widow?
Boy, you're really not afraid of a green hat after marriage, from your hairline to your heels!
"No need to inform Wanda."
Before he could finish, Karl interrupted with a half-smile, "I'm afraid Agent Romanoff won't be able to wait that long, will she?!"
Just now, Karl had already gone through Black Widow's memories using his Mind Perception ability.
He learned her true purpose this time was not just for him.
She also wanted to take the opportunity to clarify the specific content of Hydra's human experiments at the Mountain Top Base.
But because all senior employees hired by the Hyperspace Group have to undergo a long period of identity verification, the impatient Black Widow could only settle for a lesser option, setting her sights on Pietro.
She attempted to obtain relevant information from this single man through her charm.
Facts proved that her breakthrough direction was very precise!
In less than 3 days of intimate contact, Black Widow had already learned most of the human experiment content from Pietro's mouth.
However, what made her somewhat annoyed was that whenever it came to the core secrets of the human experiments, Pietro would choose to remain silent.
No matter how much she acted spoiled, it was useless.
And Pietro's reason was simple: he would die before saying anything Karl didn't want him to say.
After experiencing so much together, Pietro had long considered him family, as reliable as a brother.
What's more, anyone who wasn't blind could see that his sister Wanda had already fallen for Karl.
Therefore, even if Pietro was blinded by love, he would never disobey Karl's orders!!!
