Held in the hand of a different master, the Ame no Murakumo no Tsurugi sword began to tremble, and the authority power contained within it surged.
It was furious.
"Be just a sign for me, obediently."
An authority power even greater than Ame no Murakumo no Tsurugi gathered in Kaido's hand, pouring forcefully into the sword.
Ame no Murakumo no Tsurugi struggled even more violently.
At the same time, the already dark sky grew darker once more, and a white corona appeared around the sun, which was obscured by dark clouds, forming a total solar eclipse.
Heavy cumulonimbus clouds unleashed torrential rain, and strong winds capable of sweeping people away knocked down a large number of trees.
"What's happening?"
The mud and flagstones underfoot were stained black, and an unknown, vast authority power surged from within, its might comparable to a heretic god, causing Erica and others to pale in fright.
"I'll leave this girl to you; I'm going to the Underworld to find someone."
Kaido's body slowly sank into the darkness, a sense of dispossession, as if entering an unknown world, assailed him, just like the feeling when he first entered the Rinnoji Temple.
The Ame no Murakumo no Tsurugi possessed Susanoo's power, so Kaido used it as a guide to find him.
Originally, if the other party hadn't appeared, it would have been fine, but now that he had brazenly come out and wanted to control him using the same method he used against Kusanagi Godou, Kaido would not let such a threat go unnoticed.
When the darkness disappeared from his sight, what greeted him was a lush green bamboo forest.
Near him, there was also a gurgling stream, with clear water flowing in its bed.
An unnatural sense of aversion corroded his body, making Kaido feel disgusted.
The characteristics of the Underworld were not suitable for human flesh to survive in; even a Godslayer would weaken if they remained there for too long.
Thinking of this, Kaido did not linger, and seeing a wooden hut located not far away, he walked straight towards it.
The hut's door opened automatically, and the authority power emanating from within grew stronger.
Kaido knew that this was the other party showing their "muscle" to gain leverage in negotiations, and after a disdainful laugh, he walked into the house.
The door behind him closed automatically, revealing an old man about one hundred and eighty centimeters tall, of robust build, dressed in a coarse kimono, sitting cross-legged in front of an ancient fireplace, facing him.
"I thought you'd be too scared to see me."
Kaido knew that he was Susanoo, who secretly controlled everything, which was why he spoke without reservation.
"Oh... Is it true that all young people nowadays are as impulsive as you?" A penetrating glint flashed in the eyes of Susanoo, who wore rough clothes, but he concealed it well. "From your looks, you might have some misconception about us. How about we sit down and talk?"
This place was originally a region where humans could not set foot, a boundary between life and immortality; an unprotected human would find it difficult to move after staying here even for a second, but for a Godslayer like Kaido, the vast authority power was enough to counteract the discomfort, and staying for several months, or even longer, was not a problem.
"You're wrong about that; there's no misunderstanding between us."
Kaido walked to the front of the hearth and sat down casually, his right hand lightly tapping his fingers on the old square table, scrutinizing Susanoo in front of him.
"If there are no misunderstandings, all the better."
The robust old man filled his wine cup and took a hearty swig; as a heretic god who had been in seclusion for thousands of years, he certainly wouldn't foolishly believe Kaido's one-sided words.
The Underworld is different from the real world where humans live; it records everything that has happened since the birth of the universe, just like the "Akashic Records"; all possibilities of past, present, and future events are recorded in the Underworld.
The clairvoyance abilities of Mikos and Witches are obtained by observing the records in the Underworld and then selecting the method with the highest probability.
Over the years, Susanoo had been observing everything happening in the human world from the Underworld.
Kaido, who had appeared out of nowhere, naturally entered his sight.
The Godslayer who had killed Typhon and faced the undefeated God of War and God-King was deeply feared by him.
If Kaido hadn't forcefully read his Ame no Murakumo no Tsurugi's power and opened the door to the Underworld, Susanoo wouldn't have wanted to meet such a ruthless person.
Regaining his composure, Susanoo, feigning a hospitable attitude, began to engage in conversation with Kaido.
"As for the committee's offense against you, I learned about it; it was indeed their fault. I have already sanctioned the relevant personnel. Are you satisfied?"
Handing Ena Seishuuin to Kaido as a wife was also one of Susanoo's testing purposes.
If he could successfully befriend him, then he, Ena Seishuuin, and Kaido would form a relationship of mutual restraint.
If it failed, it would only be the loss of a Miko, with no real impact.
"Are you talking about Ena Seishuuin?"
Kaido knew that this guy was starting to waver and narrowed his eyes.
"She gives me the feeling of a wild leopard. If there's an opportunity to conquer her, I believe no man would refuse."
"Such a wonderful beauty is willing to be given away. Are you not interested in women?"
"Hahahahaha! If it were earlier, I would have been even more passionate than you are now, but after wandering the earth for over a thousand years, I've grown tired of the repetitive life."
"Erectile dysfunction is truly terrifying."
Kaido laughed playfully.
"Young man, you'd better not be too arrogant. Although you are a Godslayer, I was also a heretic god who wandered the human world in the past. While youthful impulsiveness is a privilege of youth, as an elder, I still need to give you some enlightenment."
Susanoo's tone grew harsh, and a grave and violent authority power surged within his body, causing the wooden house to tremble violently.
His true nature was not that of a pleasant old man, but of a malevolent god who, after causing chaos on earth for thousands of years, grew weary and came to the Underworld to live in seclusion.
"Being too cunning is not good. If you're smarter than others, you'll understand that cooperating with us is the best solution."
Susanoo was originally the local deity of Izumo; although he later combined many divine aspects, "concealment, cunning, and deception" were Susanoo's primary divine aspects.
"What do I gain by cooperating with you?"
Kaido asked.
"How about the land of Japan? You will become the sole king of this land; everyone will obey your orders."
"I think I can do it without cooperating with you."
Completely ignoring the oppressive aura emanating from the other party, Kaido's lips curled into a smile as he laughed softly.
Just as Susanoo's expression grew more displeased, a hoarse laugh came from the corner of the room.
It was a monk dressed in black monastic robes, whose flesh seemed to have completely peeled away, leaving dry, blackened skin clinging to his bones, giving him the appearance of a mummy.
"Hehehehe... I told you, Yu Lao Gong, negotiating with a Godslayer is simply unfeasible. They are all arrogant and presumptuous, and this brat clearly doesn't respect you at all."
The black-robed monk, provoked by Kaido's words, glared at him with malevolent eyes.
"Enough, Black-Robed Monk, Susanoo, we are not here to turn the King into an enemy today; your words are too disrespectful."
Accompanied by an elegant and clear voice, a beautiful woman dressed in the attire of a Heian period noble princess appeared in a translucent form before Kaido.
Her eyes were clear, like lapis lazuli, and her tea-brown hair and skin, as smooth and delicate as ivory, combined with her charming and exquisitely carved features, could truly be considered incomparable.
"I have shown full sincerity in cooperating with this brat, but he seems not to appreciate it."
Along with this chilling warning, Susanoo put down his wine cup, and the authority power within his body surged.
Since the other party was being discourteous, he no longer needed to pretend to be a benevolent elder.
A surging aura filled the entire room, and a powerful oppressive force weighed on the black-haired young man's nerves.
Even Kaido could clearly feel the threat of the unusual pressure emanating from Susanoo.
This was also normal.
After all, Susanoo was a powerful deity in the Shinto pantheon, the sister of Amaterasu Omikami; just the fact that he had wandered for a thousand years without being killed by a Godslayer proved his extraordinary strength.
"A little stronger than I expected, but still not troublesome."
Kaido thought indifferently to himself.
"Cooperation requires fairness, and I haven't seen any sincerity from your side."
He said.
"Your purpose in trying to conquer me is nothing more than wanting a controllable Godslayer, and thus ensuring your peace of mind in the Underworld, right?"
Susanoo and the black-robed monk sneered and said nothing.
"That's not it, we just want to live in peace with you, King."
The beautiful glass-eyed princess said anxiously.
She could see that the situation was already spiraling out of control.
"Get out of here, this doesn't concern you."
"Kaido, I..."
The glass-eyed princess still wanted to say something, but she only felt a surging authority power tearing through her.
The dilapidated wooden house instantly shattered as if it were paper, as if a Category 12 typhoon had struck, and everything was swept away by the furious wind of the authority power, turning Susanoo's residence into a pile of ruins.
"This... what the hell should I do?"
When she foresaw the danger, she immediately moved outside.
The glass-eyed princess's face was pale, and the twelve-layered robes of the ancient court noble she wore were torn by the wind blades, subtly revealing her delicate and fair skin.
Her lapis lazuli eyes gazed at the storm raging before her, her expression anxious and terrified.
Under the Godslayer's pressure, she managed to repair her clothes with authority power, thus avoiding being exposed.
If she had hesitated for another second just now, she would have been swallowed by the surging authority power.
This power and speed lived up to the Godslayer's reputation.
