People in Demon Slayer: The Journey That Began with Demon Slayer

The blood of Kibuyaku Muzan within the child surged wildly, trying to resist the injection of Yosuke's blood.

Yosuke sensed trouble; the blood of Kibuyaku Muzan within Kendo's body had spread to almost every blood vessel in his entire body.

As Yosuke's blood was forcibly injected into Mado's body, Kibuy Muzan's blood was gradually destroying Mado's body.

This means that at this moment, Kibuyaku Muzan is remotely manipulating the curse in the blood within the child's body, causing the curse to corrode his body.

The child's eyes rolled back, and his body began to rot. The extreme pain caused him to wail uncontrollably.

Yosuke kept suppressing the progress of the curse's corruption on the child, and called out to Renyuki and Komei, "Inject those two potions into its body!"

Koyuki and Komei injected the drug developed by Kanae and Shinobu, which could suppress demon cells, into Mado's body.

Yosuke temporarily stopped injecting blood, and the injected medicine began to take effect, continuously suppressing the blood of Yosuke and Kibu Muzan within Mado's body.

Just as the drug was at its peak of effectiveness, weakening the Demon King cells in Jian Tong's body to the point where the drug could exert its maximum effect, Yosuke once again injected a large amount of blood into Jian Tong's body.

This time, Yosuke's Demon King blood successfully suppressed Kibuy Muzan's blood, and the progress of the curse corroding Mado's body stopped.

The child fainted. Yosuke sensed the changes in his body and found that Kibuyaku Muzan's blood had been suppressed and his cell activity had stagnated.

However, it is only a suppression; the curse on Jian Tong's blood has not been lifted. When the suppressed blood regains its vitality, Jian Tong will still be corrupted by the curse and die.

To keep the activity of Kibuyaku Muzan's blood cells in the child's body suppressed, besides Yosuke's blood, only the potion developed by the Butterfly Sisters can work.

Yosuke hoisted the boy into his arms and said to Renyuki and Koume, "Let's go back to the Butterfly Mansion first."

On the other side, Kokushibo tumbled out of the mirror in a disheveled state.

At this moment, Kokushibo appeared in a deep mountain, a place that Kokushibo and Kendo had visited before.

Kendou's ability allows him to construct two interconnected mirrors in different locations. When Kendou used Mirror Concealment, he teleported Kokushibo to this deep mountain he had visited before.

Kokushibo's eyes were filled with rage as he wildly brandished his demon blade, venting his pent-up hatred.

Countless crescent-shaped blades swept across the entire mountain, severing countless trees in half.

Having lost the battle once again, Kokushibo was filled with resentment and dejection, wandering aimlessly through the forest.

They walked for an unknown distance and for an unknown period of time until they arrived at a plain.

When Kokushibo arrived at the center of the plain, he found it surrounded by tall trees and various blooming flowers, and discovered a tombstone.

[The Grave of Yoriichi Tsugikuni]

Kokushibo stared blankly at the tombstone, his heart filled with mixed emotions. After he turned into a demon, his human emotions and memories gradually blurred and faded. He could hardly remember the appearance of his family members, but only Yoriichi's appearance remained as vivid as ever.

Kokushibo stroked the tombstone and murmured, "Did you guide me here?"

"No! I don't believe it! You must have wanted to humiliate me to lure me here! I hate you, I despise you so much! Why are you the chosen one by God, and I am not?"

Suddenly filled with resentment, Kokushibo swung his demon blade, splitting Yoriichi's tombstone in two.

"Come out here! Yoriichi Tsugikuni! Answer me!"

Kokushibo dug up the grave soil and unearthed a coffin.

Upon opening the coffin, Kokushibo discovered that besides a skeleton, a short flute was held in the skeletal hand.

Looking at Piccolo, Kokushibo gradually remembered his past friendship with Yoriichi.

"Is your wish, brother, to become the strongest warrior in this country? Then I will become the second strongest warrior in this country."

"I will cherish this flute as if it were an elder brother!"

"I'd rather play with my brother than practice swordsmanship!"

...

"Don't say any more!" Tears streamed down Kokushibo's face as he covered his head and pleaded incessantly.

In a hazy vision, Kokushibo seemed to see Yoriichi Tsugikuni's figure.

Yoriichi looked at Kokushibo's appearance, tears streaming down his face, and sighed in a hoarse voice, "You are so pitiful, brother."

"Anyone can pity me, but not you! Yoriichi Tsugikuni! I became like this to surpass you! Come, let's have a duel! I will definitely defeat you!"

Enraged, Kokushibo continued to swing his demon blade, but the blade pierced through Yoriichi Tsugikuni's body.

Yoriichi Tsugikuni reminisced, "Do you remember? Once, my brother disobeyed Father's orders and came to my room to play without permission. When Father found out, he was so angry that he beat me up in front of everyone."

But you didn't distance yourself from me. To prevent Father from finding out, you made me a flute by hand and told me, "Whenever you need help, just play it, and your brother will come to your aid immediately."

Kokushibo continued to swing his blade: "I've long forgotten about that kind of thing!"

"But I haven't forgotten, and I think my brother must remember too. We're brothers, aren't we?"

"No! We are not brothers. I am not Kokushibo! I am Kokushibo, who will stop at nothing to become stronger!"

"Then why is your heart in turmoil, brother?"

Yoriichi's words startled Kokushibo, causing him to drop the demon blade from his hand.

Kokushibo's hands trembled as he asked himself, "Why, why is my heart in turmoil? No, my heart is not in turmoil, my original intention has never changed!"

"Brother, look at your appearance."

Looking at the puddle on the ground, reflecting his incredibly ugly image, Kokushibo couldn't help but wonder, "Is this the posture of a samurai? Is this really what I want?"

Kokushibo's belief in his own survival was greatly shaken: "Tell me, Yoriichi! What was the purpose of my birth? Tell me!"

"To me, my brother has always been the one who protects me. He just went astray, and I believe he will eventually see the error of his ways."

Yoriichi Tsugikuni embraced the bewildered Kokushibo: "I've always hoped to play with you again, like when we were little, and for you to appear by my side when I play my piccolo..."

Yoriichi Tsugikuni's figure gradually disappeared, and Kokushibo tried to grab Yoriichi's hand, but could not.

Kokushibo stared blankly at the piccolo that he had unknowingly placed in his hand.

He gently placed the flute to his lips and began to play, but the person was no longer there.

Chapter 83 Strange

For the first time, Kokushibo let go of his obsessions and faced his inner self.

"So, the reason I wanted to become stronger wasn't to surpass Yoriichi, but to be able to protect you again... Yoriichi."

As the morning sun rose, Kokushibo sat motionless in front of Yoriichi Tsugikuni's grave under the shade of a tree.

On the grave of Yoriichi Tsugikuni, under the sunlight, a blue flower suddenly bloomed.

"Blue spider lilies..."

Unexpectedly, the blue spider lily, which had been sought for hundreds of years, appeared on Yoriichi Tsugikuni's grave.

Kokushibo stared blankly at the blue spider lily until night fell again.

Kokushibo suddenly laughed: "Yoriichi, even in death, do you still want to give me a difficult problem?"

Kokushibo plucked the blue spider lily and placed it into Yoriichi Tsugikuni's coffin, then sealed the lid and buried him again.

"This time, I will no longer be confused. I hope that when we meet next time, you can play the piccolo for me yourself."

Kokushibo gripped his short flute tightly, then turned and left.

At this moment, he was no longer Kokushibo, but...

Jiguo Yansheng!

——

Yosuke, Renyuki, and Koume have returned to the Butterfly Mansion.

Kanae Kocho, Shinobu Kocho, Tamayo, Koyuki, Koume, and Yosuke are gathered around a hospital bed.

Xiaomei asked doubtfully, "Can this medicine really restore Upper Moon Six's sanity?"

“Ordinary demons, after being injected, can break free from Muzan's curse and survive with just a small amount of blood. However, this is the first time the Twelve Demon Moons have been tested. In this potion, I increased the dosage of Nezuko's blood. Should it work?” Tamayo replied hesitantly.

Suddenly, Jian Tong's body began to convulse, and the corrosion of his body and facial features began again.

Shinobu Kocho hurriedly injected a large amount of medicine that could inhibit the demon cells, barely managing to withstand the corrosion.

Kanae Kocho frowned and said, "No, the blood content of Upper Moon Kibu Y Muzan is too high. After injecting the drug, Nezuko's blood will cause the suppressed cells to regain their vitality, and she will be corrupted by the curse and die before she can regain her sanity."

"In other words, the most important thing now is not to restore its sanity, but to remove the curse of the Upper Moon blood. Only in this way can we begin the next step of the experiment," Tamayo guessed, frowning.

The Butterfly Sisters and Tamayo continued their discussion, while Yosuke left the ward, rubbing his temples.

Listening to them speak in a foreign language is truly torturous.

Lianxue and Xiaomei also left the ward, both of them feeling dizzy and disoriented.

"Sister Lianxue, can you understand me?"

"I don't understand at all!"

Kyojuro Rengoku had already left the Butterfly Mansion because he had another mission to complete, so Yosuke and the others didn't encounter him when they arrived at the mansion.

Tanjiro, Zenitsu, and Inosuke had not fully recovered and were still in the process of healing. Since it was already late at night, Yosuke did not disturb their rest.

"Lord Yosuke, will you leave immediately this time?" Kome asked cautiously.

Yosuke smiled and said, "Not for now. There are only a few of Kibu Muzan's Twelve Demon Moons left, so they will definitely stay in one place and won't come out."

"What should we do if they keep hiding?" Lianxue asked.

"It's not that patient; it's probably extremely impatient right now. I believe it will send the Twelve Demon Moons out again soon."

Compared to Muzan, I'm more concerned about what Kokushibo and Mado are searching for. Yosuke pondered, resting his chin on his hand.

"It must be the blue spider lily!" Xiaomei said confidently.

Yosuke shook his head: "Is it really the Blue Spider Lily? According to your clues, Kokushibo and Mado went to some towns. Is it really possible to find the Blue Spider Lily there? Even I don't believe that the Blue Spider Lily grows in those places."

Lianxue and Xiaomei exchanged a glance, unable to answer Yangjie's question.

Yosuke's brows were furrowed with worry: "I have a bad feeling. What Kibuyaku Muzan is looking for may be something even more dangerous than the Blue Spider Lily."

In the Infinite City.

Of the original twelve demon moons, only six remain: Kokushibo, Doma, Hantengu, Nakime, and two lower moons.

Kibu Muzan brutally murdered two Lower Moons, his body soaked in blood, and asked with extreme dissatisfaction, "Kuroshibo! Why did you fail too? Even Mado was captured."

Kokushibo replied expressionlessly, "During the battle, I encountered Yosuke Ubuyashiki, and I was no match for him."
