No time to take it, so I'll store it first!

Apart from demons capable of using Blood Demon Arts, the breathing styles used by humans possess no overt visual manifestations.

Commonly speaking, they have no special effects.

Suddenly, a guy covered in flames appears...

His way of addressing Muzan is so disrespectful... surely he couldn't be a demon.

At this moment, the flames receded slightly, and everyone saw the Ubuyashiki Family.

Unaware and unfeeling, silent tears slid down their faces.

"Master..."

"Lord Leader..."

"Leader... you are still alive... thank goodness!"

Kagaya Ubuyashiki had miscalculated one thing.

Although his death would have helped boost the morale of the Demon Slayer Corps, however...

The power ignited to protect him was by no means inferior.

The moment he locked eyes with Uchiha Sora, three tomoe emerged within Muzan's already crimson eye sockets.

A scorching sun rose within the mental space woven from flesh and blood.

Muzan had not seen the sun for a thousand years.

His psychological defenses were breached in an instant, and his naked body was dragged out of the flesh by flames to be scorched.

This guy has no resistance to genjutsu; he is even weaker than an ordinary person with a firm will.

Uchiha Sora quickly rummaged through Muzan's memories.

But he is not adept at genjutsu and cannot quickly locate useful memories like Shisui or others.

Otherwise, he wouldn't have missed such important intelligence regarding the Infinity Castle earlier.

Time is running out...

To those on the outside, it appeared that Muzan simply became dull-eyed and immobile the moment Uchiha Sora approached.

When that man placed his hand on top of Muzan's head, Muzan didn't even react.

This is... a power beyond their comprehension.

The disconnection of consciousness made it impossible for Nakime to determine Muzan's location.

At this very moment, under some kind of chain reaction, almost all the demons stood frozen in place, unable to move.

In Uchiha Sora's search, the memory Muzan held most deeply was, naturally, that man.

Tsugikuni Yoriichi.

Undoubtedly the strongest combatant in this world to date, who nearly killed Muzan in seconds hundreds of years ago, leaving him with permanent trauma.

The Transparent World...

A weakened version of the Byakugan, quite a decent ability.

Breathing styles... they have a bit of the essence of taijutsu; if this guy had been born in the ninja world, he surely could have become a powerhouse as well.

Uchiha Sora flipped through Muzan's memories as fast as he could, only to find that this guy's mind was entirely filled with Tsugikuni Yoriichi.

No way... is his psychological shadow really that massive?

After finally pushing through this shadow, what followed was Muzan's lifelong wish.

Find the Blue Spider Lily, overcome the sun, and become the ultimate lifeform!

Give me a break; the last ultimate lifeform to overcome the sun is currently floating in space, having stopped thinking.

It's too chaotic...

Muzan's thousand years of memories are too chaotic; there is simply no way to find the method to seize the Infinity Castle!

Damn it! How important is your own home? Pay some attention to it, for heaven's sake!!

Ding--

"Countdown: thirty seconds. Transmigration will begin upon conclusion. Please prepare yourself, user."

What a pain...

I shouldn't have neutralized the danger posed by those few guys earlier.

This contract was forcibly terminated upon the completion of the mission, unlike the time-limited arrangement Uchiha Sora had when borrowing Rayquaza.

It likely has to do with whether or not one possesses the platform...

Tsk!

It's all your fault, you bastard. I wasn't even using much force, so why did you suddenly lose the will to kill them!

The thousand-year-old monster I knew had far more courage and perseverance than you!

There's no time left...

Even if he obtained a way to seize the Infinity Castle, Uchiha Sora had no time to act.

Take Muzan away...

That wouldn't work. If taking him away caused that demon named Nakime to die, the connection to the Infinity Castle would be severed.

Then...

I'll just store him for now.

--

Uchiha Sora exited his mental world and looked at Tamayo, who was pressed against Muzan.

"That..."

He grabbed her shoulders and flung her away before she could say a word.

His hands moved in a blur of hand seals as he shouted.

"Gather the wooden planks and make a barrel! I'm going to seal Muzan!"

"Do as he says!"

Kagaya Ubuyashiki, who had been closely monitoring the battle, shouted urgently.

The Hashira of the Demon Slayer Corps immediately changed professions, transforming into carpenters.

Clatter, clatter—

In just over ten seconds, a crudely made wooden barrel was assembled.

"Cover him!"

The towering Stone Hashira, Himejima, swung the barrel over Muzan and thoughtfully brought over a relatively intact floorboard to serve as a lid.

Uchiha Sora pressed both hands onto the barrel, black cursed seals spreading out as sweat beaded on his forehead.

Once the black patterns covered the barrel, Uchiha Sora pulled five forbidden talismans from his ninja tool pouch and slapped them onto the wood.

After a low hum, the black patterns and talismans faded from sight, and an invisible barrier enveloped the barrel.

Ninja Art: Triple Seal Barrier!

The forbidden talismans, connected to Uchiha Sora's chakra, were placed in three separate areas, allowing the space within to be converted into a barrier.

To dispel this barrier, all three forbidden talismans would need to be torn off.

Before that, physical attacks would be unable to breach it.

The principle was the same as Pain's Five Seal Barrier, though the strength was significantly weaker.

It was more than enough to trap Muzan.

He had them make the barrel so that Muzan wouldn't be killed by the sun; this guy couldn't be allowed to die yet.

Less than ten seconds remained.

Uchiha Sora's journey to this alternate world was coming to an end.

As if by divine inspiration, Uchiha Sora suddenly understood how to leave a mark, just as Rayquaza had.

This mark served as a beacon connecting the two worlds.

To put it simply, it was a business card for an employee of the interdimensional lending company.

If one accumulated enough credit points, they could submit loan applications through the mark, or perhaps it was more accurate to say they could exchange credit points for power.

After all, for those without the platform, applying for a loan meant consuming credit points.

Kagaya Ubuyashiki must have had the highest credit points here; he surely must have prayed for Muzan's destruction, but the platform never responded to him.

In other words, his credit points were insufficient to eliminate Muzan.

It seems...

If I want to descend here again, I'll have to tell them not to be so greedy and wish for things like world peace.

He first looked toward Kagaya Ubuyashiki.

No... this guy is dying.

He scanned his surroundings.

He saw a guy with a white snake coiled around his neck and bandages wrapped around his face.

There were too many elements here; he looked so much like Orochimaru, clearly someone destined for a long life.

Before Obanai Iguro, the Serpent Hashira, could even react, Uchiha Sora arrived before him in a flash.

So fast!

He couldn't see his movement trajectory at all!

With a single finger pressed to the Serpent Hashira's brow, a black and red tomoe seal emerged.

Time was short, and Uchiha Sora said urgently, "My power can only maintain this seal for a hundred days at most. During this period, you must establish connections with as many people as possible."

"Things like helping others fulfill their wishes, or borrowing money and paying it back..."

His body gradually faded, but his mouth kept moving.

"Look for my business card, apply every day... pray for me to come and handle things for you."

"It can't be something like killing Muzan; you can't afford the price. It could be saving a cat or something... in short, ask your boss, he should be able to understand."

"Don't destroy my Infinity Castle. When I come to take it over, I'll help you guys deal with Muzan while I'm at it."

"Lastly."

"Learn from your predecessor in the other world: cherish your life, and whatever you do, don't die!"

He let out a long sigh; this was the first time he had spoken so much in such a short time.

As his voice faded, Uchiha Sora's existence vanished from this world entirely.

Only the wooden barrel sealing Muzan remained to remind everyone that this was not a dream.

The Serpent Hashira touched the fading mark on his brow, at a complete loss.
