A person in Japan, a sword that soars to immortality.

The dark clouds dispersed, revealing a bright moon and few stars.

After confirming that there was no longer any trace of Kokushibo around, Taiichi immediately sat down on the ground and began to close his eyes and regulate his breathing.

Feeling the throbbing pain in his head and the fatigue in his body, he immediately opened the panel to check his data.

【Power 2: Opponents whose spiritual power is far inferior to yours will temporarily lose their ability to move under the burst of your power】

[Common points: 15]

"To think that this breathing technique improvement would cost me 200 universal points."

"Furthermore, because I pushed the sword energy to its limit just now, my soul energy also decreased by 3 points. This is because I overexerted myself and my emotions fluctuated too much, which damaged my soul."

Taiyi frowned slightly, but then immediately relaxed.

Compared to the 3 Soul Points he lost, he discovered that he had gained another bonus effect: Divine Speed.

It's not surprising, whether it's Thunder Breathing or Metal Breathing, they are both breathing techniques that emphasize killing and increasing speed.

Therefore, it was not surprising that I obtained the "super speed" effect.

Furthermore, this battle awakened his divine consciousness, and what delighted him even more was that the three types of energy merged into one, making his sword energy even more versatile.

Furthermore, as his spiritual power increased, his control over Qi became increasingly proficient.

"Could it be that I... can develop some magic?"

A thought flashed through Taiyi's mind, and he thought with some excitement.

In this world, for pure humans, trying to harness spiritual energy and unleash incredible magic is harder than climbing to heaven.

Whether it's Demon Slayer, Hell's Paradise, or Sekiro, judging from the way the final bosses are portrayed in the original works, they all involve wielding swords and hacking away.

But look at the villains. Not to mention the demons, they can use all sorts of magical spells with ease, like Hantengu's clones, Gyokko's water manipulation, and Doma's ice crystal technique.

As for Sakura Dragon, although turning into monsters is the mainstream, his lightning-summoning technique is enough to keep him entertained.

On the other hand, humans have virtually no spells they can use.

"So... who is the true protagonist of this world? Why is it that the Yin attribute side can so easily manipulate the spiritual energy of heaven and earth?"

Taiichi rubbed his chin, his mind racing with a jumble of thoughts.

......

On the rooftop of a house in the distance, Doma was holding the arm of a human woman in his arms and nibbling on her with relish.

Meanwhile, the two demons, Daki and Gyutaro, could only stare blankly and drool.

"Oh my, Taiichi is getting more and more amazing. I'd better stay away from him next time we meet."

Doma squinted, taking in the now quiet environment, and said with a cheerful smile.

However, the wound on his neck, which Taiyi had slashed, was healing very slowly.

"Alright, the show's over. Let's go back to the master and see how Lord Kokushibo will explain himself."

"Haha, what should an adult do if he gets angry?"

"Hey? Why are you looking at me? Want some?"

Doma turned his head, looked at the two demons staring at him expectantly, their throats bobbing, and asked with a chuckle.

Uh-huh!

"That won't do. Taiichi said you can only eat corpses, but mine is still alive!"

In an instant, Douma dug his other hand into the woman's body, and as blood gushed out, a faint, painful groan escaped her lips.

He chuckled again, looking at the bewildered Daki and Gyutaro, he stretched out his pale arm, pinched his thumb and forefinger together, his seven-colored pupils darting about as he stared in the direction of the five-story pagoda, silently reciting in his heart:

"Goodbye, Taiyi. I wonder what surprises you'll bring me next time we meet..."

Snapped!

The ice butterfly fluttered slowly, while Douma had already disappeared.

At the same time, in a forest far from Edo.

Kokushibo was moving swiftly through layers of shadowy trees.

Before any obstacles could even touch him, they would be shattered by a crescent-shaped sword aura with immense destructive power.

"Yamada Asaemon Taichi, how dare you leave such a shameful scar on my body!"

At this moment, the two scars on Kokushibo's face had not yet healed, and his severed wrist was still bleeding profusely.

Because he had never been slashed by the Breath of the Sun, he couldn't experience the burning sensation that Muzan had.

However, the energy left behind by the Taiyi sword aura also caused a needle-like pain to come from the injured place of Kokushibo.

Eat people, recover.

Before he could even think, the ghost cells within his body suddenly conveyed this message to him.

Just then, by the roadside ahead, sat a tall samurai with only one arm, looking up forlornly as he drank.

"Samurai! Another samurai!" Kokushibo's eyes flickered, and blood and tears spurted out with a "plop," but he still glared at the human with hatred, preparing to devour him alive when he reached him.

"Who!" Mackenyu Takatsu, whose eyes had been glazed over, suddenly felt a chill run down his spine. He immediately sensed a whooshing sound coming from the side of him, but when he turned around, he was so startled that his hand loosened, and the bottle fell to the ground: "What is that thing!"

"Flying Sword Style: Dragon's Nest Flash!"

"Moon Soul Calamity Vortex!"

Clang!

The moment the two made contact, the sound of a shamisen suddenly rang out in the silent forest, and then a paper sliding door appeared beneath their feet.

On the other side, also with his feet touching the ice crystal mirror, a paper sliding door appeared in front of Doma as he flew through the air.

Snap...

Doma, Kokushibo, and Takatsu Mackenyu all fell into a Japanese-style room at the same time.

The two ghosts remained calm, while Mackenyu Takatsu, who was encountering this situation for the first time, quickly moved to the wall, holding his sword and cautiously observing his surroundings.

"Kuroshibo, tell me, what kind of person was the human samurai who defeated you?"

"Is he really that strong, or... has too much comfort made you complacent?"

The three of them quickly looked up and discovered that above them was an upside-down room.

A woman dressed in a kimono, stirring a beaker with a glass rod, stood with her back to them and asked a question in a chilling tone.
