He's in Marvel, working behind the scenes.

He really couldn't figure out what the reason was.

"Hahaha"

Hearing Tony's words, Gu Qing couldn't help but laugh. "You don't actually think that the changes in ghosts follow certain rules, and that they are scientific products, do you? You actually use scientific physical laws to study them."

"That's why I brought in you as my consultant!"

Tony's frustration deepened, and he said with distress, "Tell me quickly, why can knives made from these two types of minerals sever a ghost's neck?"

"Yes, it's sunlight."

Gu Qing swallowed a steamed bun and continued, "The reason why knives made from crimson ore and crimson sand can kill ghosts is because of the sunlight attribute they contain, and breathing techniques can activate this attribute."

In the Demon Slayer Corps, each member's sword is crafted by a master swordsmith from the village of swordsmiths, so there is no significant difference in craftsmanship or materials.

However, when facing powerful demons, some people can sever their necks while others cannot. This is due to the difference in individual cultivation levels, which affects the degree to which the sun attribute of the Nichirin Blade is activated.

To defeat those demons who transcend the boundaries of demons and who will not die even if their heads are severed by the Nichirin Blade, one must reach the highest level of breathing techniques and maximize the activation of the sunlight attribute within the Nichirin Blade, transforming it into a "Crimson Blade" to slay them.

In other words, Tony was completely wrong from the start to think that the Nichirin Blade could sever the necks of demons because of the density of its material.

"This is also one of the reasons why I'm not optimistic about your anti-demon armor," Gu Qing continued. "Some members of the Demon Slayer Corps also use guns. They make bullets from crimson ore and crimson sand iron, using modern firepower to kill enemies. But against powerful demons, they still can't break through their defenses."

Although the power of modern guns is incomparable to that of guns from the Taisho era, you are not facing some insignificant brats, but the Demon King Muzan and his strongest subordinates, the Twelve Demon Moons.

"So I tore up the design drawings and started over."

Tony finished the last mouthful of porridge, patted his stomach, and said contentedly, "Alright, you can play and wander around as you please, I have to get back to work."

Chapter 123 On the Eve of the Decisive Battle (Part 1)

"Is this all there is to vampires?"

Osborne Group.

Muzan looked at a vampire who had been cut in two by his subordinate and whose wounds were slow to heal, and a hint of disappointment flashed in his eyes.

Their physical abilities are barely above average, comparable to those of well-trained troops, and their healing speed is limited to minor injuries... More serious injuries, such as being cut in half at the waist or having large-area burns, take a long time to heal and require them to drink human blood.

"After all, they are just a species that lives in the shadow of humanity."

Upper Moon Four, Half-Heaven Dog glanced at it casually, revealing disdain.

There are quite a few vampire empires, and they know how to utilize everything that humans can use, yet they still have to sign agreements with humans and live in the shadows of society, and there's a reason for that.

Firth Dickin's face turned ashen.

As the leader of a mixed-blood faction who was granted the Embrace and became a vampire, he was proud of the vampires' abilities and had a strong sense of identity with the race, believing that powerful vampires should rule over humanity.

But now, these ghosts trample his pride into the ground and spit on it.

But he couldn't refute it.

Whether it's physical strength or their supposedly superior self-healing abilities, vampires are completely outmatched.

Its weaknesses include being vulnerable to garlic, silver, and wooden stakes.

There's really no way to refute it.

"These guys probably won't even be cannon fodder; they'll be wiped out by the regular human forces."

Muzan completely disregarded Dickon's feelings, saying as if no one else was around, "If you participate in the battle I plan, it will only highlight my incompetence and serve no purpose whatsoever."

"quack……"

Dickon clenched his fists so tightly that his knuckles turned white.

Muzan looked at him in surprise and said sarcastically, "You're not convinced?"

"...I wouldn't dare."

Firth Dickin was naturally unconvinced.

But seeing Muzan's mocking gaze, he immediately suppressed his dissatisfaction.

"It's a good thing to be dissatisfied."

Unexpected words came from Muzan's mouth. He chuckled and said, "If you are weak and content with being weak, then you are truly beyond saving."

What's going on with you?

Dickon stared blankly at Muzan, wondering what he was trying to do by switching between belittling and mocking him.

"Whether it's a vampire or a demon, they all originate from human cells through the transformation of blood..."

Muzan said, "Then, can demons also transform vampires? Or could the two undergo a chemical reaction, resulting in unknown consequences..."

At this point, Muzan looked at Dickon meaningfully and said, "As the leader of the new generation of vampires, do you have the courage to try?"

Dickon's breathing quickened, his face filled with a greedy desire for power.

Seeing this, Wu Can laughed.

……

laboratory.

All the scientists were summoned.

Norman Osborn looked at them and said, "Stop all projects and focus all your efforts on the company's new projects."

"What!?"

Scientists were abuzz with discussion.

Dr. Connors stepped forward and said, "Boss, my cell regeneration technology has completed animal testing. Once its stability is confirmed, we can proceed with human trials. It's practically a finished technology. If we stop now, wouldn't the company's investment be wasted?"

"Cell regeneration?"

Norman looked at Dr. Connors and said, "The company already has regenerative technology..."

As he spoke, he made a cut on his hand, and the wound healed in the blink of an eye.

Immediately, gasps of surprise rang out in the laboratory.

"How did they do that?"

Connors stared at Norman's arm, now fully restored, his eyes filled with fervor.

"This is Yueyan's research result."

Norman said, "But this technology still has a flaw, namely that users cannot be exposed to sunlight, so I started a new project to ask all of you to overcome this flaw."

Now, no one objected.

……

S.H.I.E.L.D., Tri-Wing Tower.

"Coulson, how are you?"

Dr. Tarui looked at the man chewing in front of him, his eyes filled with anticipation.

"It tastes good."

Coulson nodded in satisfaction, grabbed a strip of meat and put it in his mouth. As he chewed, he said, "It would be even better if there were less chili."

I wasn't asking about the taste.

Dr. Tarui's face darkened. "This is artificial meat synthesized from human flesh using various nutrients, possessing the same nutritional value. Did you feel any stronger after eating it?"

"I don't feel anything."

Coulson shrugged and continued eating his jerky. "Maybe I didn't eat enough, or maybe you didn't cook it very well."

"It's also possible that it only works if eaten raw."

Tarui took a piece of fresh synthetic meat from the lab table, handed it to Coulson, and stared intently at him. "Try it and see if it works."

Looking at the bright red flesh and blood in front of him, Coulson's throat bobbed, and he instinctively wanted to snatch it and swallow it.

He discovered for the first time how powerful the allure of fresh flesh and blood was for demons, and the extent of pain that Tamayo, as a demon, endured when performing surgery on people.

"No, I can't eat it."

Coulson turned his head away and took a deep breath. "Although it's synthetic meat, I have a feeling that once I eat this piece, I will never be able to resist the temptation of human flesh again."

"...I see!"

Tarui was silent for a moment, then sighed, "Then I'll continue my research and see if I can create something that will make you stronger quickly."

"Actually, you don't need to be so obsessed with researching foods that make demons stronger..."

Coulson said, "As long as ghosts are afraid of sunlight and crave human flesh, I will not live as a ghost forever."

Dr. Tarui's eyes flickered, and after a moment, he said, "...I understand."

……

Norway.

On a bright and sunny morning, with the sun still behind the clouds, a young man couldn't wait to get to the sunny beach and enjoy the warmth of the sun.

"Ugh, this feels so uncomfortable. Is this what it's like to be exposed to the sun?"

The young man shielded his eyes with his right hand, peering through the parasol and layers of white clouds at the fireball behind him, his whole body still burning with pain. Yet, he still smiled broadly, seemingly quite happy.

This is a tall, slender young man wearing beach shorts, with an innocent smile and eyes as bright as a rainbow... In his eyes are the words "Upper Moon Two".

Yes, he is none other than the Upper Moon Two, "Doma," from the Twelve Demon Moons.

Ghosts are afraid of sunlight... not the celestial body in the sky, but the light shining from it. And it has to be very intense light.

Ghosts can go out normally on cloudy days and will not be affected when hiding in the shadows.

"Master..."

A melodious female voice came from behind me.

"Lena!"

This unique voice allowed Tongmo to recognize the person without even turning his head.

He smiled, his eyes narrowing, and asked, "So, have you found the hideout of the Inhumans?"
