He's in Marvel, working behind the scenes.

After all, it's less plausible that a doctor a thousand years ago created a ghost king using medicine; it's more likely that the ghost king was born by accident.

But now, having witnessed the power of demons firsthand, and having been transformed into demons themselves, they have no choice but to believe.

Coulson took a deep breath, his gaze fixed intently on Tamayo. "Two last questions,"

"Please ask. If I can answer, I will certainly keep quiet."

"Ms. Tamayo, Mr. Yushiro, and even that Muzan and his demons are all Japanese, right? Then why are they in New York?" Coulson stared intently into Tamayo's eyes and continued, "None of you are from this world, are you?"

"That's right, we are indeed not from this world."

To Coulson's surprise, Tamayo did not hesitate or lie on this issue, but readily admitted it.

She seemed to sense Coulson's doubts and gently shook her head, explaining, "If your organization were truly a United Nations dedicated to maintaining world peace, with your resources, you would easily discover that we have no past in this world, so there's no point in hiding it."

"I see. Miss Tamayo is truly a wise person!"

Coulson suddenly realized what he meant and then offered his sincere praise.

Whether it was their performance in the previous battle or their judgment in this conversation, the other party deserved this praise.

Tamayo gently shook her head, offering no comment.

"So, does Miss Tamayo know why she traveled through time?" Coulson continued to ask.

Is this the last question?

"Well, I guess this is a derivative question of the first question!"

"A cunning fellow."

Yushiro glanced at him from the side, then turned his head away, seemingly disdainful of looking at him.

Coulson didn't seem to care, his smile unchanged.

“I don’t know.” Tamayo shook her head gently. “There were no signs before I transmigrated. I just opened the door and went outside. As soon as I stepped outside, I was in this world. When I looked back, the door and the house had disappeared.”

"I saw Lady Tamayo disappear after she went out, so I chased after her, and as soon as I went out, I was transported to another time."

Yushiro paused for a moment, then continued, "Although I followed closely behind, I arrived in this world a day later than Lady Tamayo, and the place I crossed over to was also different."

There are slight differences between this and the Vongola's time travel.

Coulson hesitated for a moment, then continued, "Was there anything special about the door you went through?"

"It's just an ordinary wooden door. We go in and out of it every day, and there's never been anything unusual before."

"I see. Then, one last question..."

Upon hearing this, Coulson knew he couldn't learn any more, so he asked his final question, "What is the relationship between Miss Tamayo and Mr. Gu Qing, or rather, what kind of person is Mr. Gu Qing?"

As Coulson spoke, he stared intently at Tamayo's expression and continued, "Both Mr. Stark and I were introduced by Mr. Gu Qing, and Mr. Yushiro's words earlier also showed great respect for Mr. Gu Qing. What is the relationship between you?"

Furthermore, you mentioned earlier that members of the Demon Slayer Corps rely on breathing techniques to fight demons.

"Gu Qing has used techniques like Sun Breathing before. Is he a member of the Demon Slayer Corps from your world?"

You scoundrel!

"Yushiro!"

Tamayo raised her hand to stop her assistant, who was about to start yelling, but the look in her eyes as she gazed at Coulson had lost its usual gentleness and turned icy.

"Mr. Gu Qing has been kind to me, and I shouldn't have revealed his information to others."

As Zhu Shi spoke, she took a deep breath and continued, "But I don't know much, and it's all unimportant stuff. Mr. Gu Qing also said that if someone comes to investigate him, he can hand over the information to the investigator for his own safety, so I'll just tell you."

I don't know who Mr. Gu Qing is, nor do I know why he knows breathing techniques. We met in this world.

When I first came into this world, I had no idea what was going on.

Mr. Gu Qing found me, told me about my situation, and gave me some money, which allowed me to settle down in this world.

Later, when Yushiro arrived, it was he who helped find him.

We have received his great kindness!

Chapter 75 Reminders and Suggestions

As Tamayo spoke, Coulson kept staring into her eyes, trying to discern whether she was lying from the changes in her gaze.

Unfortunately, Tamayo's eyes were completely calm, revealing nothing.

"...I understand, thank you for the news!"

After pondering for a moment and finding no fault in the other person's words, Coulson thanked Zhu Shi.

"You don't need to thank me. I only said so much because I wanted to use your strength to kill Muzan."

Tamayo gently shook her head, then her expression changed, and she said seriously, "Finally, I'll give you a reminder: never create demons for the sake of power and immortality!"

"...Um, is there a problem?"

Perhaps it was because Tamayo usually had a calm expression, but now she suddenly became serious, which made Coulson feel a little guilty.

Only family members know their own affairs.

As a S.H.I.E.L.D. agent, although his rank was only mid-to-high, as the director's most trusted confidant, he knew more secrets than those of higher-ranking agents.

If he returns with the constitution of a ghost, he will be investigated for whatever reason.

Since demon blood has a transformative effect on human cells, it's impossible not to create other demons to achieve the goal of creating super soldiers.

But judging from Tamayo's expression, it seemed that creating a demon would have some huge negative impact, which made him feel a little uneasy.

"The blood of a demon can infect human cells, causing them to mutate rapidly. However, most people cannot adapt to the speed of mutation and die as a result. Even if a small number of people adapt, they will not be able to withstand it and will lose their minds in a short period of time..."

As she spoke, a hint of sadness flashed in Tamayo's eyes.

Coulson successfully grasped this point and had a vague idea that Miss Tamayo had lost her mind and done something irreversible during her transformation into a demon.

"Ghosts have an instinctive craving for flesh and blood, because flesh and blood can provide ghosts with a lot of nutrition and promote their strength, and human flesh and blood are the most effective."

Seemingly having recovered from the painful memories of the past, Tamayo continued, "Therefore, demons have an innate killing intent and predatory desire towards humans. Once they lose their reason, they will indiscriminately attack those around them."

Upon hearing this, Coulson turned to look at Barbie.

I did feel a sense of anticipation upon seeing something delicious, and my mouth even started to water.

But it wasn't as mysterious as Zhu Shi described.

Turning his gaze back to Tamayo, Coulson asked, "Then why didn't I lose my mind?"

“That’s because I have a deep understanding of demons…” Tamayo lowered her eyes. “Ever since Yoriichi Tsugikuni failed to kill Muzan, I have known that it is impossible to kill him by force. The only way is to turn him back into a human.”

So for the past few hundred years, I have been researching how to turn ghosts back into humans.

Although it was unsuccessful, it did alter some of the ghost's structure and instincts, making it able to survive with only a small amount of blood and preventing it from developing a strong predatory urge towards humans like ordinary ghosts.

However, these methods are almost impossible to replicate.

In the past two hundred years, I've only created two successful examples: Yushiro and you.

"Well, I guess I'm really lucky, haha..." Coulson swallowed and couldn't help but chuckle.

Tamayo shook her head slightly, then continued, "It's getting dark, you should leave quickly, we also need to move quickly."

"Is it because Muzan discovered this place and is worried that he will send others?" Barbie asked, and before anyone could reply, she answered herself, "I think this is an opportunity. As long as we inform Director Fury about the situation here and ask him to send reinforcements, we might be able to capture the demons that arrive later as well."

Upon hearing this, Tamayo's expression changed slightly.

Yushiro added sarcastically, "So, you'll also drag us back with you then!"

Upon hearing this, Barbie fell silent.

Although she herself did not have such thoughts, if the people from S.H.I.E.L.D. were actually called in, things would definitely turn out this way.

"It could very well turn out that way."

Coulson said in a deep voice, "But this might be a good thing for Miss Tamayo."

"Good thing?"

Yushiro couldn't help but sneer, "Do you think we're from another world in the last century and don't know anything?"

Human beings crave longevity and power. Even those in the Demon Slayer Corps who are filled with hatred for demons and are of noble character can succumb to temptation and fall into depravity, let alone government authorities like yourselves.

Once we fall into your hands, all sorts of human experiments and research will begin.

Given the demon's extraordinary regenerative abilities, this experiment must have been incredibly painful.

You're telling me this is a good thing?

"Lord Tamayo just saved you, and you're already saying things like this? Have you lost all your conscience?"

“Indeed, things may, and even most likely will, develop as you say, but…” Coulson spread his arms and tried to explain, “At most, it will be blood tests or X-rays, and absolutely nothing that violates human ethics will happen.”

I'm a ghost now, and if S.H.I.E.L.D. would do something like that, I wouldn't go back.

Moreover, this only happens when there are only the two of you ghosts.

But if we could catch other ghosts, we wouldn't need to conduct these experiments.

"But the prerequisite is that you can catch other ghosts."

Besides, how do I know you're not just lying to us to find another ghost to replace yourself?

Coulson was speechless.

Although he didn't have such thoughts, people are treacherous, and no one would gamble their future on someone they don't know.

Coulson even estimated that if he hadn't been introduced by Gu Qing, the other party would probably have already kicked him out.

“Mr. Coulson, even if I’m willing to believe you, your plan is full of flaws.” Tamayo wasn’t angry at the other party’s suggestion, but remained very calm. “I don’t know what kind of power your S.H.I.E.L.D. possesses, but you’ve all witnessed the power of Arrow Demon and Handball Demon.”

After their defeat, one or more of the twelve demon moons will surely appear, and their power will be vastly different from that of the Arrow Demon and the Handball Demon.

If S.H.I.E.L.D. sends people like you, then sending more won't make a difference.

After all, demons possess incredible regenerative abilities and can accelerate their recovery by consuming humans; a human wave tactic wouldn't even be effective in depleting their stamina.

At this point, Tamayo seemed to realize that her statement was too hasty and added, "Fighter jets can handle that. I've seen it on TV; those weapons can be used to defeat the Twelve Demon Moons through distance control."

But this is a city; fighter jets can't fly smoothly here!
