Reincarnation as Lower Rank Five in Demon Slayer

In the darkness, under the silvery moonlight, a loud bang echoed from an unnamed mountain.

"bump--"

An unknown force blasted open a section of the ground in the mountains, sending a cloud of dust into the air.

A figure over six meters tall emerged from the ground. Hidden in the dust, the six-meter-tall figure looked like an unknown monster that had crawled out of the ground.

Just then, a gust of wind blew by, revealing the figure that had been hidden by dust: a gigantic black bear, standing six meters tall with a single white dot on its head, appeared in the silvery moonlight. Beside it was a large hole, five meters in diameter, that had just emerged from it.

Now, if someone were to look closely, they would discover that the white dot on the head of the giant black bear is actually a boy dressed in white with a Nichirin sword at his waist.

It was Li Lei who found Xiao Hei with Xiao Wu.

Not far away, a large black crow watched the scene unfold before it and flew towards it.

Seeing the little crow flying towards him, Li Lei immediately told the little black bear beneath him, which had already transformed into a giant bear, to lie down.

As Xiao Hei lay down, Li Lei also stepped off its head.

The little crow flew to Xiao Hei and quickly asked: Xiao Hei, how are you now? Is there anything wrong with you?

“Little Black, do you know? Three days ago, when my master and I found you, you were sleeping soundly in the hole you dug yourself.”

"When my owner and I found you, you weren't breathing. I thought you were dead when I saw you weren't breathing."

"If my master hadn't told me that he sensed from the parasitic flesh inside you that you had simply entered hibernation, a state unique to bears, due to the drastic changes in your body."

……

Seeing the chattering little crow, the black crow, which was lying on the ground, raised its head and looked at the little crow in front of it.

"Little Wu, are you worried about me?"

Upon hearing Xiao Hei's question, Xiao Wu's heart tightened. Its wings involuntarily flapped.

"Don't overthink it. I'm just worried that after you die, there won't be any animals to pull your owner's cart!"

"I'm not worried about you!"

Xiao Hei watched as Xiao Wu turned his head to the side, unwilling to admit that he was actually concerned about him.

"Thank you, Xiao Wu. Thank you so much for your concern these past few days."

Xiao Wu showed no outward reaction to Xiao Hei's gratitude, but was secretly very happy.

"It's nothing. I didn't do much to help you. You should be most grateful to your master right now."

"For the past three days, it was the master who helped you control the distribution of the parasitic flesh and blood in your body in the cave, so that the parasitic flesh and blood could be distributed in the best place in your body as quickly as possible, which is why you woke up so quickly."

"Otherwise, you might just stay here and sleep until you starve to death in your sleep."

Upon hearing Xiao Wu's words, Xiao Hei, who had transformed into a giant black bear, looked at its master beside it.

"Master! Thank you so much for your help, which allowed me to wake up so quickly. Otherwise, I don't know how long I would have remained asleep."

Li Lei looked at Xiao Hei, who was thanking him, and calmly replied: You don't need to thank me. After all, the mutation in your body was caused by the parasitic flesh and blood that I put into your body.

"Helping you is ultimately for the purpose of observing and analyzing the flesh and blood that you are parasitizing. It's not as good as you think."

Xiao Hei looked at its owner's thanks and couldn't understand why it didn't accept them. But no matter what, it still had to thank its owner.

"No matter what, I have to thank Master for his help. If it weren't for Master, Little Black would still be sleeping soundly in the underground cave!"

Li Lei looked at the little black cat in front of him, who thanked him no matter what he said. For some reason, he felt a little happy.

A faint smile, unnoticed by himself, appeared on Li Lei's face as he murmured to Xiao Hei.

"Whatever! Your thanks to me are meaningless to me anyway."

"By the way, Xiao Hei, Xiao Wu was very worried about you while you were gone. Now that you've woken up, go and catch up with it!"

Standing to the side, Xiao Wu, hearing its owner say that it was worried about Xiao Hei, said awkwardly: I'm not worried about Xiao Hei at all! It's just that it's gone, and I have no one to bully anymore.

"Okay, okay, okay! Little Wu, you weren't worried about Little Black. Is that alright now?"

Xiao Hei looked at Xiao Wu without speaking, and Xiao Wu looked at Xiao Hei without speaking either. Li Lei watched Xiao Hei and Xiao Wu staring at each other in silence.

Li Lei thought to himself: Fine! You can't act freely with me here, huh!

"Little Wu and Little Hei, I'm going to go practice my breathing technique over there. I won't disturb your reminiscing any longer."

After saying that, under the silvery moonlight, Li Lei, carrying the Nichirin Blade he had stolen from the captain of the five Demon Slayer Corps members a few days earlier at the martial arts hall, walked towards the nearby woods.

As Xiao Hei and Xiao Wu watched their master walk towards the woods, they finally began to share the interesting things that had happened to them over the past few days.

……

Meanwhile, Li Lei, who had just arrived in the woods, took out the Water Breathing artifact he had acquired only a few days prior and began to examine it.

While reading, Li Lei inadvertently recalled the information he knew in his previous life related to the Water Breathing Technique.

Water Breathing is one of the five basic breathing styles of the Demon Slayer Corps in Demon Slayer, and it is also the easiest to learn. The user's Nichirin Blade is usually blue.

Users include Tanjiro Kamado, Giyu Tomioka (Water Pillar), Sakonji Urokodaki, Sabito, Makomo, and Murata.

There are ten basic moves. Because they are suitable for beginners, they are the easiest to learn among the five styles and also the breathing technique with the most derivative styles.

Many swordsmen use the Water Breathing technique, which allows them to change their stance as freely as flowing water. They can adapt their attacks to the situation and strike the demon's neck accordingly.

Among them, the Water Pillar Giyu Tomioka created the Eleventh Form "Nagi".

However, the protagonist, Tanjiro Kamado, is not suited to the Water Breathing technique because his Nichirin Blade is black.

During a demon-hunting operation on Spider Mountain, he encountered Rui, the lower fifth of the Twelve Demon Moons. The breathing technique he learned was then used in this battle, which was his family's ancestral Hinokami Kagura.

Looking at the Water Breathing Technique in his hand, Li Lei knew the outcome of the battle between Tanjiro, the protagonist of the original work, and Rui, the Lower Moon Five.

In the end, if it weren't for the appearance of the Water Pillar Giyu Tomioka, Tanjiro's senior apprentice, Tanjiro, who had just learned the Hinokami Kagura with the help of his family's souls, would have died at the hands of Rui, the Lower Moon Five.

Li Lei calmly continued to study the Water Breathing Technique in his hand, and slowly began to learn the key points of the Water Breathing Technique.

Li Lei began to follow the key points of the Water Breathing Technique, letting go of all emotions and calming his mind, making it as still as the surface of a lake.

In the following breathing exercises, Li Lei gradually felt and controlled the rhythm of his breathing, making it change rapidly like flowing water. It could be as calm and still as a lake, as turbulent as the sea, or as nourishing as raindrops...

With a calm heart, Li Lei felt the various forms of water that condensed in nature, such as rain, lakes, rivers, and seas. He imagined himself becoming the rain falling from the sky, the calm lake surface, the river flowing through the mountains, and the sea accommodating the countless rivers flowing to the ocean.

……

After an unknown amount of time, Li Lei slowly drew his Nichirin Blade from his waist and began to wield the ten basic moves of the Water Call level.

Experience the force applied to different sword strikes and the attack characteristics of each move.

Skills like First Form and Water Slash are powerful and suitable for cutting through relatively hard objects.

For example, the Three Forms and the Flowing Dance attack move as fast as flowing water.
