While Tamayo spoke, Coulson kept staring at her eyes, trying to judge whether she was lying from changes in her expression.
But unfortunately, Tamayo's eyes were calm, and nothing could be gleaned.
"...I understand. Thank you for the information!"
Coulson pondered for a moment, couldn't find fault in her words, and thanked Tamayo.
"You don't have to thank me. I just want to use your organization's strength to kill Muzan, so I'm saying all this."
Tamayo shook her head lightly, then her expression changed and she said solemnly, "Finally, a reminder to you—don't create demons for the sake of power and immortality!"
"...Well, is there a problem with that?"
Perhaps it was Tamayo's usual indifferent expression suddenly becoming serious that made Coulson feel somewhat guilty.
He knew his own situation.
As an agent of S.H.I.E.L.D., although his level was only middle-to-upper, as the director's most trusted confidant, he knew more secrets than agents of higher rank.
If he went back with a demon's physique, no matter what the reason, he'd be studied.
And demon blood had the effect of transforming human cells. Based on the purpose of creating super soldiers, it was impossible they wouldn't create other demons.
But looking at Tamayo's expression, it seemed creating demons would have huge negative impacts, which made him feel uneasy.
"Demon blood will infect human cells, causing rapid mutation. But most people can't adapt to the mutation speed and die. Even if a small number adapt, they won't be able to bear it and will lose their minds in a short period..."
Saying that, a trace of sadness flashed in Tamayo's eyes.
Coulson successfully captured this, and he vaguely guessed that Miss Tamayo had lost her mind in the process of turning into a demon and done something irreversible.
"Demons have an instinctive thirst for flesh and blood, because flesh and blood provides demons with abundant nutrients and improves their strength—and human flesh and blood is the best."
It seemed she'd recovered from the sad memory. Tamayo continued, "Therefore, demons have a natural killing intent and desire to prey on people. Once they lose their reason, they'll attack people around them indiscriminately."
Hearing this, Coulson turned to look at Bobbi.
There was indeed a feeling of seeing delicious food in his heart, and saliva even secreted from his mouth.
But it wasn't as severe as Tamayo described.
Turning his gaze back to Tamayo, Coulson asked, "Then why didn't I lose my mind?"
"That's because my research on demons is deep enough..." Tamayo lowered her gaze. "Ever since Yoriichi Tsugikuni failed to kill Muzan, I've known it's impossible to kill him by force alone. The only way is to turn him back into a human.
So for hundreds of years, I've been researching medicine to turn demons back into humans.
Although it failed, it also changed some of the demon's structure and instinct, so they only need a small amount of blood to survive and don't have a strong desire to prey on humans like ordinary demons.
But these methods are nearly impossible to replicate.
In the past two hundred years, I've only created two successful cases—Yushiro and you."
"Then I'm really lucky, haha..." Coulson swallowed and couldn't help but laugh awkwardly.
Tamayo shook her head lightly, then continued, "It's getting dark. You should both leave. We're going to move quickly."
"Is it because this place was discovered by Muzan, and you're worried he'll send someone else?" Bobbi asked, and without waiting for an answer, she continued, "I think this is an opportunity. As long as we inform Director Fury of the situation here and have him send reinforcements, maybe we can capture the demons that come later."
As soon as these words came out, Tamayo's expression changed slightly.
Yushiro even more sarcastically sneered, "And take us back together too, right?"
Hearing this, Bobbi fell silent.
Although she herself had no such thoughts, if people from S.H.I.E.L.D. were really called, things would definitely develop that way.
"It may indeed become like that."
Coulson said solemnly, "But it may be a good thing for Miss Tamayo."
"A good thing?"
Yushiro couldn't help sneering. "Do you think because we're people from another world's past century, we don't know anything?
Humans' desire for longevity and strength—even those in the Demon Slayer Corps who are full of hatred for demons and nobility can't help being tempted and falling, let alone your government authorities.
Once we fall into your hands, all kinds of human experiments and research will follow.
And because of demons' super recovery ability, this experimental process must be full of pain.
Are you telling me now that this is a good thing?
Lady Tamayo just rescued you, yet you can say such things now. Has your conscience been eaten by dogs?"
"Indeed, things could possibly develop as you said, and there's a high probability of it, but..." Coulson opened his hands and tried to explain. "At most, blood tests or X-rays, etc. There will absolutely be nothing against humanity.
I'm also a demon now. If S.H.I.E.L.D. would do such things, I wouldn't go back.
And this only happens when it's just you two demons.
But if we can catch other demons, there's no need to conduct experiments in this area."
"But the premise is that other demons can be caught.
Besides, how do I know you're not lying to us because you're looking for other demons to replace yourself?"
Coulson was speechless. Although he didn't have such thoughts, hearts were sinister—no one would bet their future on an unfamiliar person.
In fact, Coulson estimated that if he hadn't been introduced by Quinn, they would have already attacked.
"Mr. Coulson, even if I'm willing to believe you, your plan is full of loopholes." Tamayo wasn't angry at his proposal but remained very calm. "I don't know what kind of power S.H.I.E.L.D. has, but you've seen the power of the arrow demon and handball demon.
After their defeat, Muzan will send one or several of the Twelve Kizuki. Their power is vastly different from that of the arrow demon and handball demon.
If all S.H.I.E.L.D. people are like you, it would be useless to send more.
After all, demons themselves have super recovery, and they can speed up recovery by eating people. Human wave tactics can't even exhaust their physical strength."
Speaking of this, Tamayo seemed to feel she was being too absolute and added, "Fighter jets could deal with it in time. I've seen on TV that with that kind of weapon, it's possible to defeat the Twelve Kizuki through distance control.
But here in the city, fighter jets can't fly properly!"
"It's true that fighter jets can't, but Iron Man can!"
Coulson looked at Tamayo and smiled confidently. "The treatment Mr. Stark refused was to become a demon!
But from what I know about him, knowing this method can save his life, he'll definitely conduct in-depth investigations and experiments until he finds a method with no side effects that's stable.
If he knew about the situation here, he'd definitely come in time.
No—as a hero, even without external factors, I believe he'd come to help."
