Just as Akaza was recovering his body and had just finished releasing his skills, Kyojuro Rengoku appeared behind him, charging forward with fiery speed, and used the strongest move of Flame Breathing to strike his neck.
"Your neck will always be your weakness. If one strike isn't enough, then strike a few more times. Your aura has already dropped by more than half; you can't fool me," Kyojuro Rengoku laughed, blood flowing from the corner of his mouth.
"You--" Akaza was furious. Kyojuro Rengoku was right; not dying from one strike didn't mean not dying from two or three. His power had already dropped by less than half after the first beheading and high-intensity combat.
One or two more strikes to the neck, and he would truly die... Poof!
With a loud bang, Kyojuro Rengoku's chest was pierced through; Akaza had brutally stabbed him with a hand blade.
"Mr. Rengoku--"
"Blondie--"
Tanjiro and the others in the distance, seeing this situation, charged over recklessly, their eyes wide with fury.
Uchiha Nagi's Susanoo had dissipated, so he used the fastest Thunder Breathing First Form: Thunderclap and Flash, rushing towards them.
"Ah ah ah, let go, let go!" Akaza roared at Kyojuro Rengoku, gritting his teeth in anger as he saw Uchiha Nagi about to arrive.
"Never! Come to hell with me--" Kyojuro Rengoku's sneering expression made him look more like a demon than Akaza. With one hand, he desperately increased the force on his nichirin blade, hacking at Akaza's neck, while with the other, he gripped Akaza tightly.
At the same time, burning his life force, he used his Breathing Technique to make his pierced body firmly lock Akaza's arm, preventing him from breaking free.
[That father and daughter, they're still waiting for me. I can't die. I still need to find my memories. I need to know who they are.]
"I will never let go! Come to hell with me!" Kyojuro Rengoku sneered, not only refusing to let go and using his Breathing Technique to firmly lock the opponent's hand in his chest, preventing him from breaking free, but also pressing down harder with the nichirin blade on the opponent's neck.
[Damn it--the sky is getting bright.]
At the critical moment, Akaza saw the glow of the sun behind Kyojuro Rengoku, already brightening. In less than a minute, sunlight would flood the earth.
Pfft--
Just as Uchiha Nagi arrived using the fastest Thunder Breathing First Form, Akaza severed his own arms and fled.
"Amaterasu--"
Uchiha Nagi opened his Mangekyo and used his last bit of Chakra and ocular power to unleash his strongest Ninjutsu.
"The victor has been decided. This time, it's because the sun came out. Next time, I will definitely kill you all--" Akaza's voice echoed from the forest in the distance.
"Don't run! This isn't fair! We always fight you in the night, when you have the most advantage! This isn't fair, you coward, don't run!" Tanjiro shouted, tears streaming down his face, throwing his nichirin blade with all his might, hitting Akaza in the forest.
"Mr. Rengoku, Mr. Rengoku, how are you? Waaah..." Tanjiro ran to Kyojuro Rengoku's side, crying.
"I can't go on. Listen to me, it's enough that you all survived... cough cough..." Kyojuro Rengoku coughed up several mouthfuls of blood.
Xiao Zhuzhu Inosuke (Little Piggy Inosuke) nearby was also wiping away tears, feeling extremely distressed.
"Don't cry, he's not dead yet..." Uchiha Nagi squatted down and checked Kyojuro Rengoku's chest.
"Which of the two pieces of news do you want to hear?"
"The good news is, Mr. Rengoku dodged his vital heart--"
"And the bad news?" Inosuke asked foolishly.
"Idiot, don't listen! There's no bad news!" Zenitsu smacked Xiao Zhuzhu on the head.
Uchiha Nagi smiled mysteriously, his palm glowing with green Chakra as he covered Kyojuro Rengoku's chest.
"The other good news is that I know Medical Ninjutsu and can treat Mr. Rengoku. Maybe I can save his life."
"I... cough cough..." Kyojuro Rengoku coughed up several large mouthfuls of blood.
"Don't speak. Use your Breathing Technique to cooperate with me. First, we'll reconnect the blood vessels around the heart, then the lungs," Uchiha Nagi said seriously.
Kyojuro Rengoku nodded gratefully. After all, who would willingly die if they could live? The large hole in his chest had already damaged his lungs and some blood vessels around his heart. This was the reason for his death in the original timeline, as severe lung damage prevented him from using his Breathing Technique to stop the bleeding, and damaged heart blood vessels prevented blood circulation throughout his body.
The heart, after all, is the second most crucial organ in the human body after the brain. Even a small problem can affect the entire body.
"He can be saved, right? He can definitely save the blond-haired big brother, right?" Inosuke asked, full of anticipation.
Uchiha Nagi took out a scroll and threw it on the ground. After a puff of smoke dissipated, a package appeared, filled with various test tubes and potions.
"Tanjiro, help me get that red potion, draw it into a syringe, and inject it into Mr. Rengoku. That's a blood and nutrient supplement. Also, get the red pills over there and give them to him."
"Oh, okay." Hearing that Kyojuro Rengoku might be saved, Tanjiro wiped away his tears and immediately started helping.
"Inject the green potion--"
"Inject adrenaline--"
"Inject a cardiac stimulant--"
After a while of busy work, Kyojuro Rengoku's injuries finally stabilized.
"Alright, some of the blood vessels around the heart have been reconnected, and one lung has been repaired. Mr. Rengoku, you can try your Breathing Technique now. Use it to control your body and cooperate with me to repair the other parts," Uchiha Nagi said, wiping his sweat, looking tired.
Kyojuro Rengoku nodded gratefully, closed his eyes, and concentrated.
"Hmph..." The pain in his lungs and trachea was like fire, but it couldn't stop this man of iron will.
"Hmph..." "Hmph..."
After the third breath, he succeeded. Kyojuro Rengoku began to mobilize his body's muscles and blood vessels to repair his injuries.
Uchiha Nagi swallowed another Military Ration Pill, and also fed one to Kyojuro Rengoku to restore his stamina, then turned to the young boys and smiled.
"It's a success! Mr. Rengoku's life has been saved..."
"That's great!" Tanjiro cried again, "That's truly wonderful, waaah..."
"Aow... That's great! Everyone's okay! I'm going to run a few laps..." Inosuke shouted excitedly, raising his hands.
Kyojuro Rengoku gasped for a long time, finally able to speak weakly, and smiled, "I thought I was a goner. Thank you so much, Uchiha brother."
"You're welcome. I still want to train with Mr. Rengoku. I'll think of something for your eye later. My Medical Ninjutsu can transplant someone else's eye to you, but the genes are different, the compatibility is different, and it would actually decrease your strength, so we'll have to wait patiently for a while."
Different people have different DNA, and transplantation would cause a rejection reaction. Of course, it wouldn't be as terrifying as Kakashi's Sharingan, but an ordinary person's eye definitely wouldn't be able to keep up with Kyojuro Rengoku's original eye.
After all, he can fight at incredibly high speeds, and his original eyes have already developed strong dynamic vision. Ordinary people's eyes don't have that; rashly transplanting one eye that can't keep up, while the other can, would only create a hindrance.
The ideal method would be to use Orochimaru's cloning technology to create an original eye with the same genes.
"Hahahahaha, it's just one blind eye, it's nothing. cough cough... I'm just incredibly happy to be alive." Kyojuro Rengoku laughed heartily, accidentally aggravating his wound and wincing in pain.
