He's in Marvel, working behind the scenes.

Thinking of this, Happy stared intently at Tamayo, waiting for what would happen next.

"Hearing about immortality didn't cloud your judgment with desire; truly a genius like Tony Stark!" Tamayo praised, then continued, "You're right, becoming a demon comes at a price."

"What price?"

Tony thought to himself that he had just expected this, but he remained outwardly calm.

"They eat people and are afraid of sunlight."

"What!?"

Tony and Happy stared at Tamayo in astonishment, thinking they had misheard.

Seeing their reactions, Tamayo's lips curled into a smile. "You heard me right," she said, "it's about eating people and shunning sunlight. I don't know the details of that drug, but 'demons' created with it lose their appetite for normal food, become consumed by the desire for human flesh, and are terrified of sunlight—they'll turn to ashes if exposed to it!"

"Then why did you let me..."

He stopped halfway through his sentence.

Tony remembered that Tamayo had asked him if he had a reason to live even if he became inhuman, so it seemed that she had no intention of hiding it from him.

Thinking of this, the rising anger vanished instantly, and the words of questioning he wanted to utter came to an abrupt halt.

Instead, there was endless disappointment.

He stared blankly at Tamayo, his expression dazed, as if the sky had collapsed.

He didn't want to die, he really didn't want to die.

He is Tony Stark, the most brilliant scientist of this century, the chairman of Stark Industries, and the world's most famous playboy.

He still has a wonderful life ahead of him to enjoy, and he hasn't confessed his love to his sweetheart yet. He really doesn't want to die.

With so much reluctance and unwillingness, one can imagine how much courage it took for him to calmly accept death.

Now, Gu Qing has given him hope for life, rekindling his desire to live.

As it turned out, the so-called hope of life was nothing more than throwing him from death into the abyss.

This feeling of going from darkness to light, and then falling into the abyss again... it's really unpleasant, enough to drive someone crazy.

Tony wanted to yell, to scream, to vent.

But when she looked up, she saw the most familiar Happy, Gu Qing who gave her hope, and Tamayo who offered a treatment plan...

"Let's forget about it!"

"That's settled then!"

"I just want to live the rest of my life to the fullest!"

At that moment, Tony seemed to have lost his soul, and his whole being became listless and weak.

"Don't be disappointed, Mr. Tony."

At that moment, Tamayo's voice rang out again.

Tony looked up at her listlessly, without any hope.

“Since demons are transformed from drugs, it means that this transformation is a symptom of humans that can be improved with drugs.” Tamayo said calmly, “Through hundreds of years of research, I have developed a medicine that eliminates the symptom of demons needing to eat humans. Only a small amount of fresh blood is needed.”

Upon hearing this, Tony's eyes lit up, and he regained his composure.

Although they can't be exposed to sunlight because they need to drink blood, they were able to develop a drug to overcome the urge to eat people. So they should also be able to develop a drug to overcome the need to drink blood and the fear of sunlight.

Even if Tamayo fails to figure it out and becomes a demon with an immortal lifespan, she can start learning and researching from scratch.

He doesn't believe that your own brilliant mind can't figure it out.

Moreover, fresh blood can be purchased from hospitals.

If you can't get sunlight, you can wear full-coverage steel armor, which won't cause trouble for others or affect yourself.

At that moment, Tony felt that life was infinitely wonderful.

but……

"How do you know so much about something that happened 1000 years ago?" Happy asked, pointing out the blind spot in the matter.

Upon hearing this, Tony was also taken aback, and then suddenly realized what was going on.

How do you know so much about something that happened a thousand years ago?

Even if records have been passed down, there must be some damage after such a long time!

Moreover, when people in this era see something so mysterious, their first thought is probably where the story came from, rather than exploring its authenticity!

So, why does Tamayo know so much about it?

Wait, she just said she's been researching this for hundreds of years, could it be...?

As if remembering something, Tony and Happy looked at Tamayo at the same time, "Could you be the one who became a demon a thousand years ago?"

"Of course not," Tamayo decisively denied.

But before the two could breathe a sigh of relief, she raised her right hand, revealing her smooth, white arm. "Although I am not the one who became a ghost a thousand years ago, I am indeed a ghost."

As she finished speaking, she stretched out her left hand and drew five deep, bloody lines on her fair, jade-like right arm.

However, before Tony and Happy could even be surprised, the five bloodstains healed at a speed visible to the naked eye.

[Ding! You have gained 500 Wish Points!]

[Ding! You have gained 2000 Wish Points!]

Hearing the notification in his mind and seeing the two dumbfounded people, Gu Qing's lips curled up again.

Chapter Twenty-Nine: Please Kill Muzan Kibutsuji

People often talk about things that defy common sense and enjoy discussing them.

But when something beyond common sense appears, people are not as enthusiastic as they were during the discussion; instead, they are frightened.

That's exactly what Tony and Happy were like at that moment.

After all, Tamayo had said before that demons eat people.

Although she had mentioned developing a drug to suppress the urge to eat people, being in an environment resembling a dismemberment scene, Tony and Happy instinctively felt that they had fallen into a ghostly trap like in a horror movie.

But after the initial shock, seeing that Tamayo was just standing at a distance smiling at them and did not make any further moves, they couldn't help but breathe a sigh of relief.

What followed was awkwardness.

To think that I, the dignified owner of Stark Industries, the world's most famous playboy, the greatest genius scientist of the 21st century, and Iron Man, would be frightened by a mere woman... a ghost, is truly humiliating.

"Cough cough..."

Tony coughed twice and changed the subject, saying, "I understand the details. So, what kind of reward do you want?"

After saying that, as if worried that Tamayo might misunderstand, she quickly added, "What I mean is, as a ghost who has lived for hundreds of years and has superb medical skills, you must have accumulated a lot of wealth. The reward you want is probably not as simple as money!"

"Of course!"

Tamayo smiled at Tony and said, "Before we talk about payment, I need to tell you beforehand that the recipe for turning a person into a demon has long been lost. I can only transform you by giving you my blood, using the demon cells contained in my blood. But in doing so, you will also take away a portion of my power."

"So you'll have to pay a huge price to turn me into a demon, right?" Tony thought Tamayo was trying to raise the stakes, so he replied nonchalantly, "It's okay, just name your price. If I think it's worth it, I'll agree to the deal."

Tamayo didn't answer immediately, but stared intently at him, making Tony feel extremely uncomfortable. Thinking there was something on his face, he reached out to touch it before finally speaking, "I need you to help me kill 'Kibutsuji Muzan'!"

"What?"

Tony wasn't concentrating, so he didn't hear clearly.

Tamayo's smile vanished, and she repeated coldly, "I need you to help me kill Muzan Kibutsuji!"

Tony heard it clearly this time.

But he didn't rush to agree. Instead, he asked, "Who is this Muzan Kibutsuji? Let me make this clear: I won't hurt others just to keep myself alive. If that guy isn't a heinous bastard, then there's no need to say anything more!"

“You can rest assured about that…” Tamayo’s smile returned. “After all, I only made this request because I know you quite well.”

Upon hearing this, Tony looked at Gu Qing.

"Don't look at me like that." Gu Qing shrugged innocently and pouted, "I just see who has a need and then do business with them. It has nothing to do with me."

"……All right!"

Taking a deep breath, Tony temporarily agreed with Gu Qing's statement, then looked at Tamayo again, "Tell me, who is this Kibutsuji Muzan?"

“He…” Tamayo’s expression became very solemn, and her voice became very heavy, “He is the person who turned into a demon a thousand years ago through medicine.”

[Ding! You have gained 230 Wish Points!]

[Ding! You have gained 600 Wish Points!]

Happy gaped, clearly surprised that this thousand-year-old figure was connected to them.

Tony remained expressionless, seemingly unconcerned.

However, given the system's warnings, it's clear that Tony isn't as calm as he appears.

"Although he was human, he was a complete bastard. During the treatment, because the treatment had not yet shown any effect, he maliciously suspected that the doctor who was treating him with good intentions was deceiving him, and thus killed the doctor... This is also the reason why some people who become ghosts have the defect of being afraid of sunlight, because the entire treatment process was incomplete."

[Ding! You have gained 300 Wish Points!]

[Ding! You have gained 700 Wish Points!]

Tamayo's subsequent revelations left Tony and Happy in turmoil, not only because they suddenly realized the truth about the demons' flaws, but also because they regretted the causes of these flaws.

After all, without this flaw, this drug that turns people into ghosts would undoubtedly be the key to human evolution.

But Gu Qing didn't care which one it was; as long as he had enough prayer points, that was enough.

At the same time, he was satisfied with this method of gradually laying the groundwork and revealing the truth to reap the benefits.

Admittedly, directly displaying the power of demons might create the greatest sensory shock, thereby reaping the maximum amount of prayer points.

But what happens after the harvest?

Having witnessed things of such a shocking magnitude, his experience broadened, making it difficult for him to react to things of a lower magnitude.

It's like after reaping one big harvest, you can't continue to harvest.

Unless something even stronger and more exaggerated is presented on top of this.
