Reincarnation as Lower Rank Five in Demon Slayer

Chapter 154 The Strongest Upper Moon Kokushibo

"So strong! My full-force attack was neutralized by Kokushibo with a simple slash."

"Is this the true strength of Upper Moon One Kokushibo? And this is only Kokushibo in his normal form."

Looking at Kokushibo, who effortlessly and casually swung his sword to break through his breathing technique's sword moves, Li Lei's heart was filled with turbulent emotions. Too strong, simply too strong; Kokushibo's strength was unfathomable.

Even so, Li Lei's fighting movements did not slow down at all; on the contrary, he became more and more courageous as the battle progressed.

The body, operating the Moon Breathing Technique, continuously employed sword techniques from other breathing techniques, even using Blood Demon Art as an aid, all in order to become stronger.

The opportunity to fight Upper Moon Kokushibo is a rare one. If you don't seize this opportunity to break through your limits and become stronger, you'll hardly have another chance.

Countless moon blades flew wildly through the Infinite City, slicing through everything in their path. Li Lei struggled to dodge the barrage of moon blades, searching for gaps in Kokushibo's movements to launch counterattacks.

Li Lei's sword energy grew stronger and stronger as a result of his sparring with Upper Moon One, Kokushibo. His Moon Breathing technique also improved considerably as a result.

Watching Li Lei constantly break through his limits and grow stronger, Kokushibo felt inexplicably happy. His Moon Breathing Technique finally had a successor. Although the successor's personality was quite annoying.

But since they already have successors, he can tolerate their bad temper.

"Yes, that's it! Hurry up and become stronger, I'm tired!"

As soon as he finished speaking, Kokushibo's sword swings became even faster and stronger, and he even began to use the Moon Breathing technique.

At this moment, Kokushibo had a high opinion of Li Lei and kept using sword techniques to let Li Lei feel the essence of Moon Breathing.

Moon Breathing, Form 1 -

"Dark Moon - Palace of the Night"

Kokushibo instantly unleashed the First Form of Moon Breathing, sending countless moon blades flying out with each strike, attacking Li Lei in front of him.

"Wait—Lord Kokushibo, please go easy on him." Nakime spoke up quickly, seemingly worried about Li Lei, but actually still worried about her Infinite Castle.

Hearing this, Kokushibo didn't even glance at Nakime. His sword moves were so fast that Nakime couldn't stop them at will. As Upper Moon One, he had no intention of stopping once he started using his sword moves.

This scene instantly dulled the light in Nakime's eyes, making her look as if she had been ruined by several strong men working together.

"It's over. The upcoming battle will destroy all the surrounding houses. My Infinite Castle!"

At this moment, Nakime's heart was bleeding incessantly, and at double speed.

Meanwhile, Li Lei immediately used silk threads to form a shield to defend against Kokushibo's sudden use of the Moon Breathing sword technique.

The sword technique of Moon Breathing First Form, carrying a sharp moon blade, struck. The shield made of silk threads was instantly shattered by the moon blade, turning into scattered fragments of threads.

The Moon Blade's attack continued unabated, striking Li Lei immediately. Several gashes appeared on Li Lei's blood-red battle armor, and blood splattered everywhere.

However, Li Lei's powerful regenerative abilities, combined with his parasitic blood demon technique, caused the blood that had just left his body to quickly fly back to him before it even hit the ground.

"Oh! It seems you recover very well from exhaustion."

Seeing Li Lei's incredible control over his own flesh and blood, Hei Shimu couldn't help but sigh in admiration.

"Lord Kokushibo, you flatter me. My little skill is nothing compared to what you've described."

Li Lei smiled modestly and explained that his blood recovery technique was achieved by using extensive medical knowledge combined with his parasitic blood demon technique to modify his body.

Li Lei was proud of this. His physique, through his continuous modifications, had begun to move towards the ultimate life form he envisioned. Although he was still a ghost, his potential for evolution was something that no other ghost possessed at the moment.

Of course, that excludes the protagonist Tanjiro and his sister Nezuko, as their innate geniuses are not included in the comparison.

"Lord Kokushibo, let's continue. I'd like to see your other sword techniques as well."

Li Lei was very pleased to receive praise from Kokushibo, but he didn't want to say how he did it. He knew it in his heart. He then tried to divert Kokushibo's attention.

"Alright, let's continue." Heishimu drew his sword and charged at Li Lei to continue their sparring.

Kokushibo didn't think much about the secret of Li Lei's body. It was perfectly normal that every Upper Rank Demon had a different physique than ordinary people.
