We agreed to be a tour guide, how did it become the law of nature?

The injured body quickly recovered, Akaza swung his fists like rain, and the two quickly switched from mid-range combat to close combat.

"Such exquisite swordsmanship will soon disappear from the world!" Akaza laughed, "Kyojuro! I can recover infinitely and fight with you for hours, but you can't! You can't last that long!"

"This is your tragedy as a human being!"

Akaza used both hands to block the opponent's attack that was intended to cut off his neck. Ignoring the damage to his left and right hands, he kicked the opponent hard and sent him flying.

Rengoku Kyojuro flew backwards like a cannonball and hit the ground hard.

After all, what I experienced in the dream was not real practice, and I didn’t have time to comprehend it... There is indeed a gap between me and this guy!

Rengoku Kyojuro was half-kneeling on the ground with his Nichirin Sword in his hand, his head slightly tilted back, his eyes briefly falling on Lei Dianying and the others.

With the Lord Messenger of Teyvat here, this ghost will definitely not escape, so let me fight without any hesitation!

With a reckless mind, Rengoku Kyojuro fought more and more courageously.

Tanjiro, Inosuke, and Zenitsu, who were also watching the fight on the side, wanted to help, but the speed of both sides was too fast, so fast that they could not keep up at all. Even if they forced themselves to go up, they would only be a burden.

This is not a battle they can participate in at all now!

As the battle progressed, Rengoku Kyojuro's physical strength was depleted. He was unable to maintain top combat power and gradually suffered injuries.

But there was no sign of worry in his heart. Instead, he tried his best to burn himself!

"Breathing of Fire, Fifth Form, Flame Tiger!"

"Destruction and killing, chaos style!"

The moment the two sides fought, a powerful shock wave was generated, impacting Tanjiro and others who were watching the battle.

"Kyojuro, go to hell!"

Akaza seemed to be tireless. After just launching a powerful attack, he appeared in front of Rengoku Kyojuro in the blink of an eye.

The latter swung his sword to repel the opponent, and when he was about to continue fighting, a spear swept him away.

"If you die, you won't be able to see the peaceful and prosperous times that will come, although that will most likely be very boring." Rosalia's voice sounded with almost no ups and downs.

Rengoku Kyojuro was slightly stunned, but without any pretense, he thanked him and went back directly. He had indeed reached his limit.

If only Tanjiro and others were here, Rengoku Kyojuro would do his best to protect their safety even at the cost of his life.

But there is no need to do that now, times have changed.

From today onwards, the ones who should be afraid are these ghosts who eat human flesh and do all kinds of evil!

"A woman? I don't kill women, get out of here!" Akaza was stunned at first, then uncontrollable anger appeared on his face. He felt as if he was insulted.

Akaza glared at Rengoku Kyojuro: "Kyojuro! Are you planning to run away?! Let a weak woman…"

Boom! !

He had only said half of his words when a spear suddenly appeared in front of Akaza and pierced through the joints of his two hands.

If Akaza had not reacted quickly, crossed his hands in front of him, and turned his head in time, the bullet would have pierced his head!

Hiss, it hurts!

The severe pain from his wrist made Akaza somewhat incomprehensible. This feeling was like being exposed to the sun, and even his recovery speed was suppressed!

Who is this guy?

Akaza no longer dared to be careless. He regarded the other party as an enemy of the same level as Rengoku Kyojuro, and his expression became serious.

"Destruction kill, foot style, crown first cut!"

Although his hands have not fully recovered, Akaza has already trained his body to the extreme and has many means of attack.

The spear in Rosalia's hand flowed, and her graceful body kept moving, avoiding the opponent's attack just right every time, and the spear blade emitted white light when it was swung.

If the previous battle between Rengoku Kyojuro and Akaza was a fierce one with both sides fighting head-on, Rosalia was simply toying with her opponent.

"Destruction Kill, Foot Style, Flying Star Thousand Wheels!"

The opponent's difficulty was indeed beyond imagination. It was getting late, so Akaza decided not to hold back and to get rid of this woman, then kill Tanjiro and retreat.

With a dazzling trajectory of movement, Akaza is like a wandering meteor, making it impossible to figure out his exact location.

Can you take this kick from a hundred years of practice? !

Akaza rushed towards Rosalia with a cold expression.

At this moment, the other person's figure suddenly disappeared.

what?

Akaza widened his eyes and stimulated his perception to the limit.

An extremely cold atmosphere suddenly spread throughout the place, and even the faint white mist around it condensed.

On top!

Akaza raised his head.

Boom! !

An ice spear fell from the sky and instantly pierced through his chest, continuously emitting a terrifying cold breath.

The frost continued to spread in all directions, soon covering the surrounding land and trees, forming a white area.

The sacrament of the last life.

Under the impact of the powerful ice elemental energy, even though Akaza's head was not chopped off, the powerful energy simply and roughly tore apart everything in his body.

Wow~

After the ice spear turned into pieces and dissipated, Akaza's body also shattered and completely dissipated before it fell to the ground.

Upper Three, complete annihilation!

Tanjiro, who was far away, was extremely shocked as he looked at the drastic changes in the terrain ahead.

Is this the power of Teyvat's envoy? He killed the upper rank easily!

Thinking of the other party saying that his sister Nezuko could also be saved, Tanjiro was full of hope at this moment.

【Demon Slayer: Kimetsu no Yaiba world assimilation degree 20%.】

[The blessing from the continent of Teyvat is enhanced. 】

……

The Infinite Train case is over, and the three Upper Moons, Akaza, and the last Lower Moon, Nightmare, are annihilated.

Under the leadership of the Flame Pillar Rengoku Kyojuro, Lei Dianying, Keqing and others came to a branch of the Demon Slayer Corps.

Although Rengoku Kyojuro resent the letter, emphasizing the other party's powerful abilities and expressing his approval, for safety reasons, Ubuyashiki Yoya still did not choose to meet at the headquarters.

This is a deserted and secluded town that was once attacked by ghosts. Now only a large number of old houses and ruins remain.

Except for the Demon Slayer Corps' lord Ubuyashiki Yoya, all the other pillars are present.

"It would be nice if what Kyojuro introduced in the letter was true." In the courtyard, Mitsuri Kanroji smiled slightly, "I don't know what the messenger of Teyvat looks like."

God is too far away from this world. During the period when demons were rampant, countless people called on God to come, but nothing changed.

The Demon Slayer Corps, which upholds justice, suffered heavy casualties, while powerful demons are still at large.
