It was unknown how much time had passed, but Enmu was the first to complete his evolution. Feeling the surging power within his body, he was ecstatic and immediately knelt on one knee before Kibutsuji Muzan.
"Thank you, Muzan-sama, for bestowing your blood upon me. I feel that the strength of my flesh has increased significantly. I possess power and speed far greater than before, and even my Blood Demon Art has become much more potent! Your blood is simply a gift from the heavens. Your subordinate truly does not know how to thank you... Ah! My respected and beloved Muzan-sama..."
"Hmph!"
Kibutsuji Muzan ignored Enmu, this disgusting and crazy pervert. He didn't even dare to read Enmu's memories, afraid he might see some strange things regarding himself.
Generally speaking, for something like evolution, the longer it took, the more complete the evolution would be, and the stronger the resulting power.
The fact that Enmu woke up first indicated that his cells had already reached their limit; if he continued to evolve, his body would explode and he would die. However, it also meant his strength was the weakest among them.
Not long after Enmu woke up, Rui also slowly opened his eyes. Eight spider legs, pitch-black as ink, grew from his back like eight sharp spears, capable of being used in close-quarters combat!
These eight spider legs could not only easily pierce through steel, but they also contained a deadly corrosive toxin. Like corpse-dissolving water, it could easily corrode a human body into a skeleton!
It wasn't just these eight spider legs; after evolving, Rui's skill in creating spider silk had also improved greatly. The silk was not only tougher but also coated with various poisons.
"You're awake, Rui. Congratulations on becoming stronger! Use this robust body to pledge your loyalty to me!"
Looking at Rui's strong body, Kibutsuji Muzan couldn't help but raise the corners of his mouth. As expected of his adopted son.
Because they shared the trait of being frail and sickly in the past, Kibutsuji Muzan looked after Rui very well. Even though Rui shared his power with those useless 'family members', Muzan tacitly allowed it.
Although Rui was only Lower Moon Five, his potential was even more astonishing than Enmu's. If he could reclaim the power he had dispersed, Rui might be able to surpass Enmu and inherit the position of Lower Moon One!
The fact that he woke up after Enmu was proof of this.
After Rui regained consciousness, Daki, Gyutaro, and Hantengu woke up one after another. The strength of all three had increased significantly, becoming roughly 1.5 times what it was before.
Immediately afterward, Nakime opened her single eye. Originally purple, her pupil had now turned an intense crimson red.
Upon waking, blood-colored flames suddenly ignited on Nakime's hands. Strangely, these flames possessed no temperature, appearing as if they were merely illusions.
However, as she tightened her grip on the biwa in her hands, the blood-colored flames instantly ignited the instrument. The biwa, originally made of wood, transformed into bone, and bat-like bone wings grew from both sides of it.
Her entire aura was far more powerful than before, and her burning fighting spirit was even comparable to Akaza.
"Is this my biwa? This is truly the most perfect instrument, hehehe..."
Gazing at the bone biwa in her hands, Nakime revealed a rare look of excitement, even letting out a somewhat maniacal smile. Her slender jade fingers brushed over the strings as she held the bone biwa, unable to put it down.
"With this bone biwa, I can not only control the Infinity Castle freely but also play the Death Demon Sound I have dreamed of!"
The Death Demon Sound, as the name implied, meant that once one heard that demonic tune, death was not far away.
The principle was simple: use the bone biwa to play terrifying ultrasonic waves, and use these waves to continuously impact the enemy's internal organs, eventually completely destroying the enemy's viscera and brain.
Although it was useless against demons, for the members of the Demon Slayer Corps, this move was a veritable sound of death!
"Nakime, I didn't expect you to evolve to this degree. Sharing my blood with you was indeed the correct decision." Kibutsuji Muzan reached out and caressed Nakime's long black hair, and Nakime seemed to enjoy it very much.
"It is this subordinate's honor to receive your praise!"
"That biwa woman..."
Watching Nakime receive Kibutsuji Muzan's favor, Daki was furious. As the only other female demon among the Upper Moons, Daki had always viewed Nakime as a competitor.
Even back when Akaza was still alive and Nakime had not yet become an Upper Moon, Daki had found her an eyesore.
In her heart, the only person who should receive Kibutsuji Muzan's appreciation was herself!
Being so close to Daki, Kibutsuji Muzan naturally sensed her petty thoughts, but he didn't care.
Letting his subordinates compete was highly beneficial for him as their boss.
At this moment, Doma also rubbed his sleepy eyes and regained clear consciousness. His entire body exuded a biting cold aura, and white frost even began to form beneath his feet.
"My, my, is this how it feels after evolving? This feeling is really nice!"
It wasn't just an increase in physical strength; even the power of his Blood Demon Art had been enhanced.
previously, he needed to use his fans to unleash his ice-based Blood Demon Art, but now, merely breathing could release biting ice crystals. Once inhaled, they could easily pierce the alveoli of ordinary people.
If he used his iron fans, he could whip up an extreme cold storm!
By this point, everyone had finished evolving except for Kokushibo.
When he finally completed his evolution, it was already two and a half hours later. Upon completion, Kokushibo said only one sentence.
"My Moon Breathing, Seventeenth Form, is finally complete!"
Once all the Twelve Kizuki had evolved to become more powerful, Kibutsuji Muzan cut his own palm, controlled his blood to flow into test tubes, and distributed his blood to Kokushibo and the others.
"I have shared my blood with you. Use this blood to mass-produce Mad Demons. With these Mad Demons, you will surely attract the attention of the Demon Slayer Corps! When that happens, I presume that brat Ren will also come out to slay demons. At that time, with your increased strength, you will definitely be able to obliterate him! Hahaha..."
Kibutsuji Muzan laughed maniacally and ordered Nakime to send everyone out of the Infinity Castle.
Starting now, the era of the Night Parade of One Hundred Demons would arrive once again!
...
"Tanjiro, don't run! Cut towards the rock!"
As he spoke, Ren lifted a rock the size of a basketball, assumed a bowling stance, and hurled the crushed stone toward Tanjiro.
A short half-month had passed, and Tanjiro had already completed his strength training. Next up was improving his swordsmanship.
The rock flew out like a cannonball, smashing straight toward Tanjiro.
Seeing the rock tearing through the air, Tanjiro's face turned pale with fright. He hurriedly scrambled to escape, shouting as he ran.
"I don't understand, Big Brother Ren! This is too dangerous!"
"You want to run, don't you? As long as you can cut through the flying rock, you can cut through a demon's neck."
"You're joking with me, right? Big Brother Ren, you are definitely joking with me, right!"
"Do I look like I have the leisure to joke with you? This is..."
"Northwest!"
Suddenly, the Kasugai Crow, Tianyue, descended from the sky, shouting frantically: "Lord Ren! A demon has appeared at Mount Yaqi in the northwest direction, causing massive casualties. Lord Ren, please go and provide support immediately!"
