He's in Marvel, working behind the scenes.

"There's still an hour until dawn!"

Just as everyone was exhausted from the stalemate with Muzan, the Kasugai Crow gave the timely message of time.

Everyone was taken aback, but their weary spirits were immediately lifted.

One hour.

If they can hold on for just one more hour, they will win.

Muzan, after glancing at the dimly lit sky, became anxious.

He cherished his life extremely and had an abnormal desire to live.

After nearly being killed by Yoriichi Tsugikuni, he hid and didn't come out until Yoriichi's lifespan was exhausted, at which point he reappeared to cause trouble.

Now, even though there's still a full hour left, I'm already feeling like giving up.

I have endless life, which is not even in the same league as these worthless lives. How could I possibly risk fighting them?

No, we have to retreat.

Thinking of this, Muzan unleashed several whips from beneath his feet, lashing out and cracking the earth.

The attackers retreated and dodged.

Muzan seized the opportunity to break through and escape.

"Don't even think about running!"

Tony, piloting his Jaeger, caught up, launching a special missile with his left hand and wielding the Sun Sword with his right, charging through the air.

Parker also leaped over from the rooftops along the street.

Further back are Kanroji Mitsuri and Iguro Obanai.

"Bugs, leave me alone!"

In his rage, Muzan unleashed an endless barrage centered on himself.

Tony and Parker, who had just gotten close, were blasted away and embedded in the wall.

"Ok?"

Seeing this, Muzan had a question mark appear above his head.

When did I become so weak?

Even the Blood Demon Art, which unleashes its trump card, can only cause this much damage?

No, these people have already been injured by me, and their bodies have been poisoned by a deadly toxin that destroys their flesh and cells. They should have died long ago.

But why is there no response?

Furthermore, it's quite unusual that these people, with their level of competence, have managed to drag this out for so long.

why?

Muzan noticed something was wrong, his mind raced, and he finally found the key to the problem in Tamayo's memories.

It was Tamayo who created the serum ahead of time that could neutralize the cell-damaging virus.

She injected herself with multiple poisons.

When Tamayo and Shinobu were making poison, they agreed that the poison should be made based on the premise that Muzan could decompose the toxins. Therefore, they added a special ingredient that would cause the body to age rapidly to the drug that turned the demon back into a human.

In this way, even if Muzan cannot be turned back into a human, he can be made to age fifty years every minute under the influence of the second drug.

"So that's how it is. My body has been aging continuously. If I calculate the time, I've already lost over nine thousand years of my lifespan in this short night."

Muzan suddenly realized what was happening, and at the same time flew into a rage.

"Tamayo, Tamayo, are you going to oppose me even in death?"

The anger in his chest erupted and was drawn out as power.

Suddenly, the streets were filled with giant craters, as if struck by a meteor shower.

However, as the body ages, so does the mind.

So much so that even with such a dense barrage of attacks, everyone managed to dodge and then charged forward with their knives.

At this moment, Muzan truly panicked.

The reason he survived even after being beheaded was not only because he had transcended the boundaries of demons, but also because of his ability to change his physical body. He had seven extra hearts and five extra brains growing inside his body, which constantly changed position with the flow of blood.

If these vital points were destroyed simultaneously by the Nichirin Blade in an instant, he would die just as well.

And right now, there is such a possibility that these people are attacking together.

So

"You all should die!"

Desperate, Muzan pulled out a detonator and pressed the button without hesitation.

"boom!"

With a deafening roar, flames rose up on the towering streets of New York, the impact and heatwave spreading so intensely that even people in the next block could feel it.

Fortunately, S.H.I.E.L.D. contacted the government in advance and had the crowd dispersed early on, thus preventing more innocent people from dying.

However, in the center of the battlefield, only ashes and corpses remained.

Amidst the smoke and dust, Muzan's body slowly coalesced.

Looking at the razed streets and the Demon Slayer Corps and heroes lying in the ruins, he laughed loudly, "See? No matter how bumpy the road was, I still won in the end."

It turns out that before deciding to take action, Muzan had planted a large amount of explosives produced by the Osborn Group within the Infinity Castle to prevent the situation from spiraling out of control.

Anyway, even if they are dismembered, they can regenerate.

But people can't.

At this time, the remaining ghosts also began to slowly recover.

Black Death Eyes, whose body was still coalescing but whose head had already recovered, looked at the pillars who had just fought him but now lay among the wreckage and couldn't help but sigh, "Humans, even if they cultivate to such a powerful level, are still fragile."

"you"

Parker pushed away the beam pressing down on him and stood up groggily.

Despite being unable to stand steadily, he still stood in front of Muzan.

On the other side, Tony activated his mech suit, wanting to stand up and help.

However, the power unit completely shut down after emitting a puff of black smoke.

Ruined.

Tony lay lifeless beneath the wreckage, his face ashen.

In this situation, he couldn't even get out of the mech.

"Ha, a centipede!"

Muzan sneered as he looked at Puck, who was stubbornly blocking his way. "Poor thing, let me send you to heaven!"

As he spoke, he was about to lash out with the whip behind him.

But then a dark shadow descended from the sky.

"boom!"

A two-meter-long iron pillar, as thick as a large bowl, fell from the sky, crushing Muzan's head into minced meat from head to toe, and driving it deep into the ground.

Then, another enormous figure descended and smiled at them.

Hulk has arrived!

Chapter 149 System Upgrade

Ding! Your B-rank, two-star doll "Kuroshibo" has died!

Ding! Your B-rank and 3-star doll "Kibutsuji Muzan" has died!

As dawn broke and the first rays of sunlight streamed in through the window, a death notification from the system rang in Gu Qing's mind.

As the death notification sounded, the flood of system notifications suddenly slowed down.

But then, even more messages started appearing, continuing for half an hour before gradually slowing down. Eventually, only scattered small amounts of prayer value data popped up from time to time.

The frequency isn't too slow, but it's much slower than the previous spamming. At this rate, barring any unforeseen circumstances, I should be able to get another 20,000 to 30,000 wish points.

"So-so."

Gu Qing looked at the balance of 1.26 million on the system panel and nodded in satisfaction.

Although Muzan detonated the bomb in the end, causing many people to die before they could even react, it also brought the sadness, despair, and hatred of Parker, Tony, and others who were watching the battlefield to a peak, providing 210,000 prayer points.

But they are not the main force this time.

The big head is Hulk.

With an inherently irritable constitution, under the control of nightmares during sleep, Banner, who had lost everything, and Hulk, who had nothing, obtained what they had always dreamed of, only to have it taken away in the most cruel way.

This level of stimulation pushed Hulk's rage to its extreme, directly generating over 400,000 wish points, bringing the total to over a million.

"As expected, Hulk is my benefactor."

Gu Qing recalled the series of large data entries that flooded the screen, and her eyes narrowed into slits with laughter. She wondered when she could have a few more like that.

Or, when I have the ability, I'll go to other universes and find other Hulks to play with.

However, the harvest was gratifying.

Unfortunately, a lot of the chives died.

Although the group left the Infinity Castle in pursuit of Muzan, they caught up with him before going too far and did not stray too far from the castle.

The bombs buried in the Infinity Castle were Muzan's trump card for turning the tide after the situation spiraled out of control. They were so powerful that they affected even the surrounding neighborhoods.

Although the exact number of deaths is still unknown, those who fought vampires and the Hand in the ruins of the Infinity Castle will definitely not escape.

In other words, Patton and Natasha are basically doomed.
