Chapter 141: I'm a Doctor!
At this point, considering the three Upper Rank demons he had already slain, this little demon was most likely a subordinate brought along by the last remaining Upper Rank.
Kokushibo? Doma? Akaza?
The strength of those three Upper Rank demons was terrifying. Compared with an Upper Rank Four, the difference was practically a sheer cliff.
Ren had no intention of fighting any of them right now.
Engaging them at this moment would only increase the casualties among the Demon Slayer Corps.
Clang!
Ren's Nichirin Sword flashed and suddenly appeared before the little demon.
The little demon was so frightened that it wet itself.
"Don't kill me!"
Ren pressed the Nichirin Sword against its neck.
"I ask. You answer."
The little demon nodded repeatedly.
Ren asked, "Who is the other Upper Rank this time?"
The little demon shook its head.
Ren's Nichirin Sword sank halfway into its neck.
"I'll give you one more chance to think carefully."
"I don't know! I really don't know! I only know that my lord carries a fan!"
A fan?
Ren's eyes darkened.
He understood.
Seeing Ren fall into thought, the little demon cautiously asked,
"Can I leave now?"
"Yes."
As he spoke, Ren directly severed its neck.
"This way, you'll leave faster. No need to thank me."
And just like that, the little demon died beneath Ren's Nichirin Sword.
He had originally thought Ren would simply leave afterward.
Unexpectedly, Ren suddenly turned his head and said sternly,
"Go back and tell your Upper Rank master that I have something to say to him."
"You emotionless thing. What exactly are you pretending to be?"
As soon as Ren's words fell, a figure several hundred meters away trembled slightly.
It was a demon possessing a Blood Demon Art!
It realized that Ren seemed to have detected its presence and immediately fled far away.
Ren sheathed his Nichirin Sword without pursuing it.
After awakening his Regression State, Ren knew there was something more important waiting for him.
So, in the next instant...
Just as Ren was about to return his Nichirin Sword to its sheath, Uzui Tengen suddenly rushed over from behind him.
He had just been struck by Gyutaro and crashed into the Kyogoku House. After forcing his way back out, he discovered that Ren had already gotten there first and severed the demon's head.
He had chased after Ren all the way here and finally found him.
Uzui Tengen approached Ren, panting.
"Ren, you're seriously rude! At least leave me some face!"
Although he said that, the Sound Hashira had a smile on his face.
After all, defeating an Upper Rank demon while still alive would give him an absolutely tremendous achievement to brag about for the rest of his life!
But Ren suddenly looked at him.
"Don't move. You've been poisoned. The poison will spread."
"Poison?"
Unexpectedly, Uzui Tengen waved his hand dismissively.
"Ren, you don't know this yet, but I'm from a family of shinobi. This little bit of poison can't hold me back."
The very next moment—
Uzui Tengen collapsed unconscious.
"Lord Tengen!"
"Dragon Hashira!"
Hinatsuru and the others rushed over as well, arriving just in time to see Uzui Tengen lying on the ground.
Suma suddenly burst into tears.
"Waaah! Lord Tengen really died in battle!"
A heavy slap landed on Suma's head.
Makio angrily said,
"Suma, if you don't have anything useful to say, then keep your mouth shut! Lord Tengen is only poisoned!"
Hinatsuru quickly knelt down to examine Uzui Tengen's condition.
Both of Uzui Tengen's cheeks had already turned almost completely purple-black, while the veins throughout his body were horribly swollen.
The poison had clearly penetrated deep into his bloodstream, and his life could be in danger at any moment.
Makio noticed the tension on Hinatsuru's face and asked worriedly,
"Hinatsuru, how is he? Is he all right?"
Hinatsuru didn't answer.
The atmosphere was extremely oppressive.
At that moment, Uzui Tengen slowly opened his eyes.
When he saw the others, a smile appeared on his face.
"Why are you all looking so gloomy? Didn't we win?"
Hinatsuru's eyes filled with tears.
"It's all my fault, Lord Tengen. I wasn't able to help much."
Suma also looked as though she was about to cry.
Even Makio, normally the strongest-willed of the three, was visibly emotional.
Just as Uzui Tengen was about to deliver his final words, Suma and Makio suddenly began arguing.
Uzui Tengen immediately wore a classic speechless expression.
"No way. Can't I even leave a final message?"
At that moment, Ren walked over.
However, Suma blocked his path.
"Dragon Hashira, please let Lord Tengen pass away peacefully."
The Sound Hashira opened his mouth, seemingly wanting to say something, but Makio immediately interrupted him.
"Lord Tengen, your injuries are too severe. Please don't speak."
Uzui Tengen: "???"
Uzui Tengen became extremely anxious, but the poison had already spread to his throat, making it impossible for him to speak.
Seeing this, Ren could only smile bitterly.
"What are you talking about? Did you forget that I'm from the Butterfly Mansion?"
When they still looked completely bewildered, Ren simply said,
"I'm a doctor!"
His words fell.
Everyone seemed to awaken from a dream.
Oh, right!
The Dragon Hashira was the legendary doctor of the Butterfly Mansion.
In their panic, they had completely forgotten that fact.
Hinatsuru looked at Uzui Tengen's resentful little eyes and couldn't help giggling.
Uzui Tengen silently stared at Ren.
As it turned out, his instincts had never been wrong.
Ren was the person in whom the Demon Slayer Corps had placed its greatest hopes.
And the facts had proven that placing their hopes in him had been the right decision.
After all, the Demon Slayer Corps had not slain an Upper Rank demon in a very long time.
Yet Ren and he had created a miracle the Demon Slayer Corps had not witnessed in more than a century!
The two of them were simply incredible!
Uzui Tengen's excitement only caused the poison to spread even more rapidly.
Ren looked at him.
"Stop daydreaming. Try using your Breathing Technique to prevent the poison from spreading."
As he spoke, Ren gently placed his hand against Uzui Tengen's chest.
Uzui Tengen felt a warm current flow throughout his body.
Then his heart suddenly began beating violently.
Could this be Total Concentration Breathing—Constant?
But it was useless.
Uzui Tengen had already tried it.
This poison unique to Upper Rank demons could not be dealt with by Total Concentration Breathing—Constant.
Otherwise, he wouldn't have ended up in such a miserable state.
Just as he was thinking this, Uzui Tengen suddenly felt his body become much lighter.
"What is this?!"
Uzui Tengen was shocked.
He suddenly realized that the poison inside his body seemed to have stopped spreading!
No.
This wasn't Total Concentration Breathing—Constant at all!
"Remember this feeling."
Ren suddenly spoke.
"This Breathing Technique was developed by me. Used over a long period, it can stimulate the activity of the cells within your body, allowing the body to repair itself to a certain extent."
Uzui Tengen nodded.
He knew that Ren had never disappointed him.
The next moment—
Ren slowly closed his eyes.
[Transparent World activated.]
[A Transparent World unfolds before your eyes.]
[You have seen directly into Uzui Tengen's body!]
