Invincible in the world, starting with the ghost curse

After bidding farewell to Tanjiro and Steel Pattern, Kamiya Seiichi decided to go back to his room to rest.

He stretched lazily. Although he didn't run, the distance he moved was the same. Rounding it off, it was equivalent to the time he ran for.

So self-deceiving.

He took out his own sword and unsheathed it. Kamiya Seiichi's face was reflected on the snow-white blade. He was really satisfied with this sword. Not only was it hard and able to withstand the high temperature of the red sword, but its properties were also neutral and peaceful. When switching breathing methods, it would not damage the sun blade itself.

After playing with it for a while, Kamiya Qingyi decided to continue practicing. He honed the Breathing of Yang, Breathing of Sun, and Red Blade one by one, and his proficiency was steadily increasing.

Now, Kamiya Seiichi only has one skill left to master, and that is the Transparent World. The Transparent World is similar to the ability of the Byakugan in Naruto. They are actually very similar. Both can observe the opponent's bones and veins like X-rays. On the other hand, they have a high increase in seeing through the opponent's actions.

If breathing techniques significantly increase a swordsman's strength, then they also significantly enhance their perception, allowing the user to clearly see their opponent's anatomy, predict their movements, and increase their attack and evasion speeds. Simply put, it's like their dynamic vision is maxed out.

The key to unlocking this world of transparency lies in precise breathing and movement, allowing for maximum power with minimal effort. To activate this, the swordsman must shut off all other senses. Through repeated correct movements, they achieve a transparent view of the opponent's internal state, then strike with swift force, delivering a single strike that ultimately kills the foe.

Repetitive actions are very common in Demon Slayer, but it doesn’t matter to Seiichi Kamiya.

For him, who is almost at the Tao, it is not difficult to learn it, but when there is no reference object, it may take some time to invent it. Just like the red sword, he also gained some insights from the red tip of the sword when Tanjiro's sword cut into Roku.

But it won't take much time, Kamiya Qingyi thought. Being so close to the Tao is truly heaven-defying. Give him another month, and he's confident he can chase Muzan everywhere in this world.

While Kamiya Seiichi was resting, the Infinite City on the other side was bustling with activity.

"The courtesan Taro is dead."

Muzan, holding the dropper, observed his experiment. He put down the test tube, slowly raised his head, and his scarlet eyes moved downward, staring at the upper string below.

“You guys disappoint me so much!”

He swung his left hand violently, smashing all the bottles and jars on the table. His face became increasingly ferocious, and he pressed his temple with his right hand.

“For hundreds of years, you have done nothing!”

"It seems that because of your status as Upper Ranks, I have indulged you too much."

The atmosphere was extremely cold.

The first to speak was an excited figure—no, a ghost, really. He looked nothing like a human. His upper body resembled a human, with arms and a chest, but his lower body was a mere pot. Where his eyes should be, he had two green lips. Instead, his forehead and mouth had eyes. "Wan Qi" was engraved on the golden iris of his upper eye, and "Five" was engraved in the lower eye. It was the Five of the Upper Qi—the Jade Pot.

"Lord Muzan, I found the place where the Demon Slayer Corps forges their swords. Please..."

"Oh, boring, extremely boring."

Before the sound stopped, in just a moment, Yu Hu's head appeared in Wuzan's hand, covered in thick blood. The body on the pot had fallen to the ground like a corpse, and bright red blood was flowing.

"What I want is news about the blue spider lily!"

He threw Yu Hu's head down, blood splattering everywhere. Wuzan turned around, glanced at the trembling figure lying on the ground, and disappeared into the darkness.

"After verifying the news, Yuhu, take Bantian Gou with you."

"Yes, Master Muzan!"

Yu Hu, who had just received his head, excitedly said this. He then looked at the figure lying on the ground. It was a hunched old man, but upon closer inspection, he had the appearance of a demon. There was a huge tumor on his forehead and two horns on his head. Strangely, his eyes didn't have the word "upper string" and the corresponding number engraved on them like other upper string celestial beings.

"It's obviously the Upper Four." Yu Hu licked his tongue and was not ready to leave the Infinite City. He retracted half of his body and looked at the two figures on the platform with interest.

One is a white-haired man sitting on the ground, smiling innocently and happily like a child, swaying his body from side to side like a tumbler. He has white oak hair, wears a black cape, and has "Upper String" and "弐" engraved on his rainbow-colored irises.

One was a man standing upright, his back to Douma. He had short peach-pink hair, golden eyes, pale skin, and dark blue tattoos all over his body. Aside from the inscription "Upper Rank Three," his eyes were filled with unhappiness.

"Ahhhh, what's the news, Yuhu?"

Without looking at Akaza anymore, Douma stood up and walked to the jade pot, poking the pot with his finger.

"Did Master Muzan give you any orders?"

A cold voice came from behind.

boom!

As soon as he finished speaking, Douma's head was smashed by a punch, and the upper part of his head exploded into pieces of flesh. Akaza was standing behind them at some point, his raised right hand covered in blood, indicating that he was the one who did it.

Swish!

A stream of blood splattered as Akaza's right hand was directly cut off by the plane.

"You've gone too far, Akaza."

Plain words rang out in Akaza's ears. His pupils shrank slightly. Standing behind him was a man with long crimson hair in a high ponytail.

"If you're not convinced, you can start a bloody battle."

Turning around to look at Akaza was a face with six eyes, "One of the Upper Moons".

"Ah, Lord Kokushibo, I'm just playing with him. Besides, even if we start a bloody battle, he's no match for me, right, Akaza?"

The strands of flesh on his head intertwined, and the injuries instantly recovered, and Douma said with a smile.

Akaza's veins bulged, but he didn't move.

"Give up that meaningless persistence, Akaza." Muzan slowly emerged from the darkness and came back.

Akaza immediately half-knelt in greeting, Douma also sat up straight, and Kokushibo bowed slightly.

"Lord Muzan, why..."

"Because I changed my mind." Muzan's deep eyes made it impossible to decipher any meaning. The only sound in the air was the shivering of a dog.

Bladesmith Village.

"The hot springs here can even heal injuries. It's true that the world is full of wonders."

Tanjiro and Seiichi Kamiya were on their way to a hot spring on the mountain. Seiichi Kamiya was dragged here by Tanjiro. However, he was reluctant because Seiichi really wanted to try the feeling of a hot spring bath.

As soon as I reached the stairs at the foot of the mountain, I heard a crisp sound from afar.

"Tanjiro! Seiichi-kun!"

Kanroji, in a bathrobe, ran down the stairs.

"Listen to me, listen to me! I was just ignored, woo woo woo."

Ganlu Temple had a mournful look on his face and was spinning around while holding the two of them.

Kamiya Seiichi, feeling a bit dizzy from being shaken, laughed in silence. Thus began the "ordinary life" of the swordsmith village.
