I'll kill you after I finish this game!

"Understood, Lord Muzan."

Without any hesitation or question, Nakime gently stroked the biwa in her arms, and with a soft twang of the strings, the large paper doors around her were all pulled open with a bang.

Hundreds of figures with different appearances appeared outside the paper door, all exuding a terrifying aura as they descended into the Infinity Castle to receive Muzan's summons.

"Anyone who dares to hinder my ascension to godhood is trash that needs to be swept away!"

As the powerful demons walked in one after another from outside the paper door, Muzan Kibutsuji's eerie face revealed a sinister grin.

Countless dense, fleshy needles began to spread from his back. Through these fleshy tentacles and bone spur needles, he could distribute his perfect blood to these demons, making them stronger!

He was about to throw all these evil spirits into the battlefield and wipe out those eyesores in one fell swoop.

The rewards on the system panel, which only he could see, made Muzan both envious and insane. At first, it was for survival, and he wanted to keep living until eternity.

Now he has a greater ambition: to continue evolving and reign supreme on the throne of the gods!

........

Meanwhile, Raize, who was interested in the underworld of this world, sent his Shadow Companion to the underworld of Demon Slayer.

What interests Razor in this world are the breathing techniques and the fact that the blood of those demons is of considerable value.

He had already obtained the breathing techniques from the Demon Slayer Corps, since Raizet had truly saved their lives and given them divine weapons like the Demon Sword and the Holy Sword.

The breathing technique was also very smooth.

As for the blood of the demons, that will be left to our own ship girls to handle, while Muzan will become his experimental subject on his testing ground.

Now, having crossed the boundary between life and death through the power of the Ghostly Grail, Reiji, with his golden hair flowing like the sun and his tall and upright figure carrying the golden holy spear, is walking in a dark tunnel.

The further you go, the stronger the aura of death becomes.

"Crash-!"

When Rezer had completely passed through the exit, he heard a strange river god. What came into his view was a dark gray sky and a deathly gray river with countless distorted human faces, exuding a cold, deathly aura.

This is a place that doesn't belong to the human world. The sky is just a dark gray with no other bright or vibrant colors, and the whole world lacks corresponding warm light.

In the sky, a black sun hung suspended, casting a cold light that was naturally black and devoid of any warmth.

Having passed through the spatial tunnel and stepped onto the land of the underworld, Rei Zhe raised his eyebrows as he looked at a wide road ahead, where countless souls were constantly heading towards the other side.

A group of people with numb expressions walked across the desolate land, stretching as far as the eye could see. The whole world gave Razer a feeling of oppression and desolation.

On the earth, a wide river flows down from the horizon, its waters as black as ink, and faint cries can be heard coming from the riverbed, sending shivers down one's spine.

"It seems this is the Sanzu River..."

Lei Zhe looked around with interest, finally focusing his gaze on the pitch-black river, and muttered to himself.

This is the legendary dividing line between the world of the living and the world of the dead.

Ahead, Reiji heard that strange river sound; it was the Sanzu River.

The river's flow is divided into three different speeds—slow, normal, and rapid—based on the deceased's actions before death.

Therefore, it was called the "River of Three Crossings".

In Lei Zhe's intrigued gaze, there was a ferry boat in the river ahead, and a ferryman shrouded in a black robe stood there, his face obscured, exuding a chilling aura.

People with blank expressions kept walking to the shore. Each ferry was full of people heading to the other side of the river. The boat was small and inevitably bumped in the wide river. People on the edge lost their footing and fell into the water. Before they could even struggle, countless hands reached out from the river and pulled them to the bottom. There were no more ripples.

This is the River Styx, the river that separates the living from the dead. In Japanese folklore, it is known as the Sanzu River.

As the dividing line between this world and the afterlife, there is only one way for a soul to cross the "River of Three Crossings".

That was to take a ferry on the Sanzu River; there was no other way.

If a soul accidentally falls into the River of Three Crossings, it will never be able to escape.

Because the waters of the Sanzu River have no buoyancy and contain a deadly poison that can corrode the soul.

Therefore, those souls who risked crossing the river will never have the chance to return to shore. They will become water ghosts in the "River of Three Crossings," unable to attain Buddhahood for eternity and suffering the icy torment of the river for all eternity.

Under such torment, these water ghosts became envious of other souls who still had hope of attaining Buddhahood.

Once a soul falls into the water, they will swarm to it, drag it to the bottom of the river, and turn it into a water ghost, subjecting it to the same torment.

The east bank of the river is a magical place between life and death, while the west bank is the true land of death.

After death, one will pass through the boundary between life and death and arrive at the riverbank. The spirit will lose consciousness the moment it steps in, no matter how powerful it was in life.

Only after crossing the Sanzu River and reaching the other side will the soul regain its independent consciousness. Some people who still have attachment to the human world will stay on the other side, constantly observing those they still cherish from the boundary between life and death.

With a smile, Lei Zhe followed the other souls to the Sanzu River, which was filled with dark death energy and deadly poison. Looking at the large number of souls wailing in the river, he felt very pleased and reached out his golden holy spear into the river.

A strange fluctuation spread through the Sanzu River. Reiji opened a passage to his Valhalla Demon Castle as if fishing, and released the aura of life as bait.

A golden spatial vortex emanated from the Sanzu River, radiating a conspicuous aura that was extremely alluring to ghosts!

"Woooooooo..."

All the souls still wailing in the Sanzu River were stunned for a moment, then revealed expressions of ecstasy and excitement.

After sensing the different aura and life force of their kind, they surged towards the golden demonic realm like a group of sharks smelling fish.

These water ghosts had been suffering from the deadly poison of the Sanzu River for an unknown amount of time.

Now they feel and see a completely different world. Even knowing that it is a hell where people fight each other in eternal time and space, they are willing to go there.

Because they are not qualified to pursue better goals, they can only pursue an environment that is not worse than their current one.

Very quickly, at a speed visible to the naked eye, tens of thousands of wailing souls in the River of Three Crossings disappeared in a short period of time, measured in seconds.

Over countless ages, countless souls have suffered in the Sanzu River.

Tens of thousands, millions, tens of millions...

Countless souls poured from the River of Three Crossings into the unknown golden demon realm of Valhalla, beginning an endless battle.

In the Sanzu River, the ferryman, who had just finished transporting a boatload of souls, sensed that the number of wailing souls in the surrounding water had decreased significantly, and looked towards the Sanzu River with some confusion.

He was terrified when he saw it; he almost dropped the oar.

The number of souls suddenly disappeared, a situation he had never seen before in his thousands of years of ferrying souls. Following the direction the group of souls had gone, he saw a golden figure that made his eyes widen.

Those are living beings? How could living beings have come to the River of Three Crossings?!

However, seeing that a large number of souls in the River of Three Crossings had been taken away by the figure wielding the golden holy spear, the ferryman roared in fury:

"Baka! What are you doing, you bastard!?"

"Ok?"

Lei Zhe shifted his calm yet fiercely oppressive gaze over there, his golden eyes burning with immense, high-density soul power.

The moment the gaze fell upon the ferryman of the Sanzu River, his ugly face, which looked like skin glued to a skeleton, was immediately revealed beneath his black robe.

"Gah!"

Like a dead duck being choked, Razer's gaze, carrying immense weight, descended upon him, and his body immediately slammed onto the ship.

Wow...

"Crack, crack..."

The entire boat, along with the ferryman, was rocking and groaning on the Sanzu River. Dense cracks appeared all over the small wooden boat, and it looked like it was about to collapse, be destroyed, and sink into the Sanzu River.

"...Spare me! Spare me, sir!"

The ferryman, no, the ghost, clung tightly to the small boat, his withered and decaying face pressed against the vessel. Gone was the initial anger; he began to beg for mercy in a cowardly manner.

Well, it seems that whether in the human world or the underworld, might makes right is a universal truth.

"Humph!"

Lei Zhe snorted coldly and stopped when he saw that he had extracted enough souls. He didn't know if his actions would have a bad influence on the underworld of this world. He had no extreme thoughts of destroying the world, so he wouldn't go too far.

He has already extracted tens of millions of souls from the River of Three Crossings, which is enough for him to use for a long time.

The man who ferryed people across the Sanzu River also felt the terrifying gravity on his body disappear.

despair......

Just as the ferryman was about to get up, a pair of feet appeared in front of him. He swallowed hard, whether there was any saliva or not, and nervously raised his head, trembling as he looked at the handsome young man with long golden hair in front of him, who was looking down at him with a calm and cold gaze.

"Take me across the river!"

Lei Zhe commanded in a cold voice.

"Ah? Sir, are you going to cross the Sanzu River?"

The ferryman stood up somewhat awkwardly, looking shakily at the young man radiating immense pressure before him, and asked in surprise.

"Stop talking nonsense and get me across the river!"

A terrifying aura of death emanated from Reiji, intimidating the ferryman before him. Reiji spoke with slight impatience,

The death law aura emanating from him, which was as solid as a material, was a combination of the laws that had once devoured that demigod necromancer, Xiaoyou's understanding of death, and even the transformation of the human world into the end.

"Yes, yes, yes! I'll take you across the river right away, sir!"

Sensing the intense aura of death about to engulf him, the ferryman wisely refrained from asking any further questions and immediately began ferrying passengers.

Lei Zhe squinted his eyes, carefully sensing the aura of hell around him. After being ferryed across the River of Three Crossings, he carried the Golden Holy Spear and, amidst the awe-inspiring gazes of the ghosts on the other side, strode confidently into the depths of the underworld.

"Where did this old man come from? Is he some kind of big shot who escaped from the depths of hell?!"

The ferryman watched Lei Zhe's retreating figure with awe and trembling eyes. Recalling the intense aura of death emanating from Lei Zhe and the spiritual energy in his eyes that seemed to embody hell, he wondered if Lei Zhe was some kind of being who had escaped from hell.

Lei Zhe didn't care what the ferryman thought of him. After walking for a while, he saw some bright red datura flowers, also known as spider lilies, blooming on both sides of the road leading to hell.

Out of interest and curiosity, he picked quite a lot, and even took some of the hellish soil, putting it all into his backpack.

Once a soul enters this place, it will be inexplicably guided to some other-dimensional place.

Sensing the intricate and complex nature of these strange spaces, some small and some large, Reiji guessed that they were the so-called hell used to punish evil spirits.

Lei Zhe perceived sixteen enormous hellish spaces most clearly.

Eight of them emanated a scorching aura like that of a raging inferno, while the other eight emanated a deathly and icy aura.

If Lei Zhe's guess is correct, the first eight spaces with scorching heat should be the Eight Hot Hells.

The eight hot hells are the hells of living beings, black ropes, multitude, howling, great shouting, scorching heat, great burning heat, and Avici Hell.

Following that are the Eight Cold Hells, namely, Ebhuta, Nirabhuta, Atata, Apopo, Huhupo, Apopo, Padma, and Maha Padma.
