Luo Men found it difficult to describe what kind of person Muzan was; he couldn't even be considered a person, but merely a monster who would stop at nothing to survive.
Thousands of years had long since stripped this fellow of human emotions; were it not for the existence of Yoriichi Tsugikuni, he might not even know what fear was.
And now, Luo Men, having inherited Yoriichi Tsugikuni's soul and mastered the Transparent World, the Mark, and the Crimson Blade, truly was the closest existence to Yoriichi Tsugikuni in this era.
As for the gap between him and Yoriichi Tsugikuni, Luo Men understood it even more clearly after personally experiencing Yoriichi Tsugikuni's first-person perspective.
The current Luo Men was incredibly strong, uniquely powerful among all the Pillars in the Demon Slayer Corps.
But even that strength was insignificant before Yoriichi Tsugikuni.
Without mentioning anything else, the ability to unleash fifteen hundred slashes in an instant was something the current Luo Men could not achieve; even with an overloaded burst, Luo Men could only unleash five hundred to eight hundred slashes in an instant.
Moreover, fifteen hundred slashes was not Yoriichi Tsugikuni's limit, but something he could accomplish in a hurry, which speaks volumes about Yoriichi Tsugikuni's power.
Of course, just facing Muzan in his current terrified state, Luo Men was more than enough. However, to completely eliminate Muzan, the current Luo Men was still a bit lacking.
Therefore, Luo Men's current goal was to display enough combat power to force Muzan to retreat, yet not so much that Muzan would hide from him for most of his life out of fear, like when he encountered Yoriichi Tsugikuni and kept his distance, never daring to approach.
Not only that, but he also needed to actively provoke Muzan's desire for revenge, making Muzan proactively seek him out.
This was very difficult; exerting full power was always simpler than holding back.
However, something Luo Men hadn't anticipated happened: Muzan said nothing, simply turned and fled, at an incredibly absurd speed.
"This won't do."
Watching Muzan flee, Luo Men narrowed his eyes and instantly switched his Breathing Technique to Thunder Breathing.
[Thunder Breathing, First Form: Thunderclap and Flash]
The characteristic of Thunder Breathing was speed, and the First Form of Thunder Breathing pushed this aspect to its extreme.
By using the Breathing Technique to guide the free-floating energy particles of the world, then concentrating and gathering them on his legs to stimulate and activate them, Luo Men, accompanied by golden lightning, traversed a great distance and appeared behind Muzan.
A dangerous chill appeared behind him, and Muzan knew it was the swordsman's attack.
In just an instant, one of Muzan's legs separated from his body, and because he lost a leg, Muzan immediately fell to the ground.
"There seems to be a threat, but it's not particularly strong, and he seems to be using Thunder Breathing."
Based on the sensation of his body being slashed, Muzan realized that the opponent's strength was very high, at least not inferior to the Pillars of the original Demon Slayer Corps, perhaps similar to the current Kokushibo, but compared to Yoriichi Tsugikuni, it should still be a bit weaker.
Muzan could confirm that this man knew Sun Breathing, but he certainly had not reached Yoriichi Tsugikuni's level. Thinking this way, the threat level increased significantly, but it was no longer as terrifying as Yoriichi Tsugikuni.
In fact, making Muzan have such thoughts was precisely Luo Men's goal.
This way, Muzan would exert himself more in the future, and when his strength further improved, he would still have a chance to meet Muzan and slay him.
However, if there was an opportunity to slay Muzan, Luo Men wouldn't mind eliminating the menace right away this time.
But after estimating the time, there were at least two to three hours until dawn, so it would still be difficult to weaken Muzan with the sunlight debuff and then directly slay him.
Therefore, the goal this time was to make Muzan resent him, and then later, by throwing out bait like the Swordsmith Village or the Blue Spider Lily, coupled with his hatred towards Luo Men, Muzan would definitely not refuse to personally make a move.
"Brat, you've angered me."
Saying this, feeling his previous loss of composure, Muzan angrily spoke and then directly began attacking Luo Men.
His hands instantly transformed into two stinging whips, lashing out at Luo Men with astonishing speed. The incredibly flexible stinging whips were not only fast in attack but also had a considerably large attack range.
When it came to body modification, Muzan was definitely a master. Aside from the weakness of sunlight, Muzan's physical body truly had no other obvious weaknesses.
[Thunder Breathing, First Form: Thunderclap and Flash - Eightfold]
Compared to the Thunderclap and Flash, which could only attack in a straight line, the Eightfold had many more variations, and the additional multi-stage attacks caused more damage. Moreover, Eightfold was not the limit of this technique; if possible, it could be an infinite combo, depending on whether it was necessary.
Luo Men, using Thunder Breathing, was even faster than Muzan's stinging whips.
In just a few moments, as these stinging whips were cut off, Luo Men had already struck many vital points within Muzan's body.
Muzan had five brains and seven hearts within his body, and they were not fixed in one place; they could move continuously according to Muzan's thoughts.
However, under Luo Men's high-speed combat style, Muzan had barely reacted before many of his vital points had already been destroyed.
Of course, Luo Men also knew that such an attack was not truly fatal to Muzan; the injuries left by the Crimson Blade were merely severe wounds. His ability was still very different from Yoriichi Tsugikuni's.
However, even just this much made Muzan incredibly terrified.
Although this man was not comparable to Yoriichi Tsugikuni, he was still an extremely terrifying existence.
Once again, he felt fear and hesitation.
Time was running out. If he continued to drag this out until dawn and the sun rose, he might just perish here, and that was something he absolutely would not allow.
"Luo Men-ge, what are you doing?"
Just then, a clear voice rang out, and Luo Men felt a sense of unease; it was Nezuko's voice.
Acutely sensing Luo Men's discomfort, Muzan's eyes darted, and a plan to escape instantly formed in his mind.
Luo Men, this extremely fast enemy, was in a state where he couldn't be touched, nor could he be escaped from, making him incredibly troublesome.
But if he were to turn that girl who made the sound into a demon, perhaps this man would no longer have the mind to deal with him. He knew the conflicted attitude these humans had towards their loved ones becoming demons.
Thinking of the plan, Muzan also whipped out a stinging whip, accurately piercing Nezuko, but instead of harming her, he injected his own blood into Nezuko.
"How will you face this little girl?"
For Muzan, there was no shame in such a sneak attack on a powerless human girl.
But ultimately, Muzan had no warrior's honor or sense of dignity; to survive, he would do anything.
Having done this, he turned and fled again, with no intention of engaging Luo Men further.
And Luo Men, seeing Muzan's fleeing figure and thinking of Nezuko's state, felt a headache coming on.
Originally, when he determined there was no way to slay Muzan, he had intended to find an opportunity to hold back and allow Muzan to successfully escape, but he hadn't expected Nezuko to suddenly appear. Was this the inertia of history?
Nevertheless, he turned and ran towards Nezuko's direction to check on her condition.
