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

Rengoku Kyojuro did not consume too much physical energy in dealing with Nightmare. He did not want to leave all the matters to the messenger of Teyvat, as that would make the Demon Slayer Corps seem incompetent, so he planned to do it himself this time.

The train stopped in a dense forest. It was very quiet all around, with only the faint chirping of insects.

The pitch-black night, coupled with the faint white mist rising from the forest, made visibility extremely poor.

Whoosh!

A figure suddenly appeared, almost naked from the waist up, with strange ink-colored patterns painted on his skin, and he wore a pair of white trousers. The pattern of Upper Rank Three was printed in his pupils.

Rengoku Kyojuro had just left the carriage with Tanjiro and others, and he instantly noticed the figure coming, and the two sides made eye contact.

The Third of the Moon!

Tanjiro and Inosuke instantly tensed their bodies and gripped the hilts of their swords with their right hands.

The same is true for Zenitsu, but his heartbeat is even faster than the other two.

No matter why this Upper Moon comes, a war is definitely inevitable!

The third moon in the waxing phase is Akaza.

After confirming his target, Tanjiro, his figure, which was originally squatting on the ground, suddenly jumped out.

Boom!

The violent explosion caused the soil under his feet to collapse deeply, and as the shock wave spread, Akaza's figure had already appeared in front of Tanjiro.

He clenched his right fist, and delivered a powerful blow that made the air explode. The power was so astonishing!

So fast!

Tanjiro's eyes widened and a look of horror flashed across his face.

"Breathing of Fire, Form Two, Rising Flame Sky!"

Rengoku Kyojuro's reaction was equally fast. The moment Akaza rushed over, the long sword in his hand had already been unsheathed.

A flash of hot fire passed by, and Akaza's fist and arm were cut directly.

A trace of surprise appeared on the other party's face, and then he exerted force on his feet and moved back more than ten meters.

In just a blink of an eye, Akaza's palm, which was cut into two pieces, had closed and returned to its original shape, without even a drop of blood escaping.

Is this the upper string? Such a strong pressure!

Facing this kind of enemy for the first time, Tanjiro and the others were extremely nervous.

In the carriage nearby, Lei Dianying and others also came out to continue watching the show.

"So this is an Upper Rank demon. Although its aura is much stronger than that of a Lower Rank demon, it is still very weak." Kamisato Ayaka said.

Lei Dianying didn't say anything. At this moment, she was thinking about a topic that Shen Fei had once talked about.

Intensity, or level.

The universe is vast and infinite, and the strength of creatures born in different worlds is different.

Perhaps someone who has reached the top in one world will find, after going to another world, that he is not even as good as the cattle and horses there.

Rather than being discovered by some indescribably powerful being in the universe one day, it is better to find ways to increase your own strength and reach the top level in the universe.

At the very least, this can preserve civilization from being eroded and from existing as prey.

Just like the current world of Demon Slayer, for the Demon Slayer Corps here, the Upper Ranks are already a powerful opponent that is difficult to deal with. However, in the eyes of Kamisato Ayaka and others, even if there is world suppression and the strength that can be exerted is limited, it is not a difficult task to get rid of this demon.

This is the absolute suppression of lower life forms by higher-level life forms, or high-intensity life forms!

"Woman?" Lei Dianying, Keqing and others who suddenly appeared were quickly discovered by Akaza.

However, he only took a glance and then looked away, focusing all his attention on Rengoku Kyojuro and Tanjiro.

Useless weaklings only make him feel disgusted. The only one who can slightly arouse Akaza's interest here is Rengoku Kyojuro.

"How about I give you a wonderful proposal?" Akaza suddenly said to Rengoku Kyojuro, "Would you like to join us and become a demon? I can tell at a glance that you are a pillar, right? The power in your body is very strong, but you are always just one step away from reaching the highest level, and you will never be able to reach the highest level!"

"Become a ghost, get rid of the fragile and aging body of humans, so that you will have enough time to practice, 100 years, 200 years! A nearly infinite lifespan will make you a truly powerful person!"

Akaza's description was quite beautiful, but Rengoku Kyojuro was not moved at all.

"I am one of the nine pillars, the Flame Pillar, Rengoku Kyojuro. Give up your stupid idea. I will not become a ghost! It is because people will age and die that we know how to cherish and love the people and things around us."

"What a shame." Akaza assumed a fighting stance. "If you don't want to become a demon, then go die!"

Boom!

The violent force crushed the earth, and as the dust scattered, the two figures instantly fought together.

The scorching flames and the blue light continued to intertwine, so fast that Tanjiro and others could not see clearly at all.

This ghost is very fast and very powerful!

However, compared with the messenger of God who came from Teyvat, the gap between the two is like an insurmountable chasm!

Rengoku Kyojuro thought to himself that having experienced the devastation of the thunder movie in his dream, he could now deal with the Upper Three with ease.

"We are both pursuing the highest realm of martial arts. I really can't understand why you are so resistant when only the chosen ones can become ghosts?!"

Swish!

Akaza's tone was full of contempt. Although his palm was easily cut off by the opponent, these attacks were ineffective. As long as his neck was not cut off, no one could kill him!

swoosh~

The severed palm flew back and closed together instantly. This is the power of ghosts. With almost infinite lifespan and strong recovery ability, they can easily defeat any enemy!

The way Akaza looked at Rengoku Kyojuro was like the way a higher life form looks at a lower life form.

"As the Flame Pillar, you are indeed very strong!" Akaza raised the corners of his mouth, outlining a happy arc, "Use the last moments of your life to please me!"

"Destruction Kill, Sora Style!"

Akaza punched out in mid-air, a blue light flashed, and a powerful attack came instantly.

Although he can't see it, Rengoku Kyojuro has developed a keen sense of threats under the high pressure of Lei Dianzi.

His body moved to the side without hesitation.

Boom!

A punch force invisible to the naked eye hit the ground, and the soil shattered like tofu, revealing a huge deep pit and debris flying everywhere.

Akaza attacked more than once, but they were all completely avoided by the sharp-minded Rengoku Kyojuro, and the latter's agile figure kept approaching.

The blazing flames ignited, and Rengoku Kyojuro stared at the other party with cold eyes: "You are just a guy who only sees the world from a well, you don't know what true power is! The end of demons has come!"

Breathing of fire, three forms, all things in fire!

Boom~

Akaza's right shoulder was cut directly. Originally, Rengoku Kyojuro was aiming at his neck, but he dodged quickly enough.
