When Chinatsu saw Tanjiro take out so many test tubes filled with his own blood, she quietly withdrew her arm.
Tamayo, realizing what was happening, held the test tubes filled with Chinatsu's blood as if they were priceless treasures, her eyes burning with passion and clarity.
Tamayo: This...so much! How many experiments can I conduct with this?!
Tamayo's eyes gleamed with a sharp, almost daring light, and she nearly lost her composure... no, she had already lost her composure. At least, Yushiro beside her had never seen Tamayo like this before. But no matter what she looked like, Miss Tamayo was the most beautiful person in his eyes.
Tamayo returned home laden with her research findings, while Chinatsu and Tanjiro quickly left her residence. They could contact Tamayo if she completed her research or if any problems arose.
If you were to ask who the biggest MVP was in the battle of the Infinity Castle, it would undoubtedly be Tamayo and Shinobu Kocho, who developed the ultimate poison that could age Muzan.
In the original work, the ultimate poison required two people to work together to concoct, and in the world that Chinatsu interfered with, this ultimate poison was also indispensable.
Chinatsu is ultimately not the embodiment of Yoriichi Tsugikuni, nor is she a monster who surpasses Yoriichi Tsugikuni... at least not now.
Muzan is very strong. Even after being poisoned by the ultimate poison, his strength is still far superior to Kokushibo's, not to mention his full strength before being poisoned by the ultimate poison. Therefore, this ultimate poison is necessary to make him age and weaken.
Chinatsu and Tanjiro walked along the road at night, concealing themselves as they returned to the Demon Slayer Corps headquarters.
The "humans" are ramping up their combat power, while the "demons" are also ramping up theirs.
After Kokushibo's death, Muzan gave a death order to his ordinary demon subordinates who didn't even have the strength of a Lower Moon.
For Muzan, fellow beings are not necessary. If it weren't for needing these laborers to find the Blue Spider Lily for him, he wouldn't want to create even a single companion.
At this moment, something that can replace the blue spider lily has appeared, and these demons, who are not even considered lower moons, only have two paths to take.
First, he was forcibly injected with Muzan's blood, becoming a mass-produced Lower Moon, and then turned into cannon fodder in the battle of the Infinity Castle.
Second, they would sacrifice their last bit of value, desperately searching for the Demon Slayer Corps headquarters or Chinatsu's whereabouts.
Muzan chose the latter.
Muzan's voice echoed in the minds of these demons, and intense fear surged from their hearts. Regardless of what they had been doing before, upon hearing Muzan's voice, they immediately knelt down, covered in sweat.
[You bunch of worthless trash who have my blood flowing through your veins but haven't provided me with even the slightest value. I'll give you one more year. If you still can't prove yourselves, then you have no reason to continue living.]
This sudden, devastating order caused most of the remaining demons to stop slacking off and frantically search for the Demon Slayer Corps headquarters or Chinatsu's whereabouts.
How many people who become ghosts are not afraid of death?
However, they did not know that even if they found the Demon Slayer Corps headquarters or Chika, they would still be unable to escape being wiped out by Muzan.
In conclusion: Either way, you're going to die, but you'll have to work yourself to the bone before you die.
The Demon Slayer Corps members were unaware of this death order given by Muzan, but they were surprised to find that the cannibalism had decreased during this period.
On the surface, this seems like a good sign, but in reality, everyone feels that with five Upper Moon demons dead, this unusual scene is definitely the calm before the storm...
As dawn broke, Chinatsu and Tanjiro returned to headquarters. Chinatsu rubbed her eyes, saying she needed to sleep for a while. This wasn't simply because she was lazy; sleepiness just crept in on her involuntarily. Perhaps it was a lingering effect of her body not yet being fully recovered.
Chinatsu yawned heavily, while Tanjiro said he wanted to go find Inosuke. He knew Inosuke had gone to train with someone, but he didn't know who he was training with, and he was curious.
After reminding Tanjiro not to overwork himself and to get some rest, Chika turned around and went back to her room in her mansion. With a "plop," she lay down on her soft, large bed and closed her eyes, drifting off to sleep.
Tanjiro stood still, took a deep breath, stretched his arms, and then randomly chose a direction to begin his journey to find Inosuke.
As dawn broke and rays of sunlight streamed down from the sky, Kyojuro Rengoku, who was meditating inside the Demon Slayer Corps headquarters, slowly exhaled.
There was no one else in his residence except him, because Kyojuro was basically always on missions and spent very little time at headquarters, so no other people were assigned there.
If someone were inside his residence and saw Kyojuro, who had remained motionless for dozens of hours, they would definitely be extremely worried.
Kyojuro's fighting spirit has been constantly changing over the past few dozen hours. As one of the two people among the nine pillars of the Demon Slayer Corps who are closest to the "Transparent World," Kyojuro has now come into contact with the barrier of that supreme realm.
Kyojuro might have needed several years or even more than a decade to get into this field before, but after absorbing Akaza's top-tier experience package and receiving Chinatsu's concept transfer, Kyojuro experienced a leap in growth.
The key to unlocking the world of clarity lies in the resonance between the breath and the body, but before that, one must abandon superfluous and useless senses and concentrate wholeheartedly on the liberation of the five senses.
The concentrated breath flows and intertwines between the muscles and blood vessels of the body. This process is extremely painful and difficult. One mistake can lead to complete failure and having to start all over again. Therefore, the mind must be calm.
A transparent world is a state of selflessness.
By focusing your breathing and creating a perfect resonance with your body, over time the opening and closing of muscles and blood vessels will be completed quickly and easily in the blink of an eye, just like how a person naturally and logically opens their eyes when they want to see a scene.
After enduring the pain to accomplish all of this, the world you see will change, a realm that can only be reached through the utmost effort.
Sweat dripped down Kyojuro's cheeks as the first rays of dawn shone on them.
Kyojuro slowly opened his eyes, and the scenery before him had undergone subtle yet enormous changes.
If someone were to appear in his line of sight now, he could even see through their muscles and blood vessels. Upon seeing this scene, he revealed a bright smile.
"I...succeeded..."
