Muzan Muzan sat quietly in a chair, the bright electric light dispelled the shadows around him, and illuminated the whole room like daylight. He liked this kind of light, which could bring brightness without hurting himself. In Muzan Muzan's hand, he held an old collection of poems from the Warring States period, the pages of which were slightly yellowed, revealing the vicissitudes of time. Muzan Muzan's daily life was spent quietly in human society like this. He liked to appear as an ordinary person and integrate into this complex and changing world. Muzan Muzan was not in a relaxed mood. He had not turned the poetry collection in his hand for a long time. He felt inexplicably irritated in his heart, as if something was happening quietly, but he could not figure out the specific reason. When he was about to turn the Warring States poetry collection in his hand to the next page, Muzan Muzan's right thumb trembled slightly. Muzan Muzan turned his head towards Taiko County, frowning. It was fine if the waning moon died, but how come even the waxing moon had problems? He extracted the last memory of Jifu Taro, wanting to know what happened. Under Muzan Muzan's gaze, Jifu Taro's memory before his death was played out like a movie, with every detail clearly visible.
After reading it, Muzan Muzan put down the book in his hand, and his fingers tapped the table unconsciously, which was his habitual action when thinking. Lin Yi's appearance made Muzan Muzan see the shadow of Tsugikoku Yoriichi. Muzan Muzan couldn't help but think of the memory of hiding in a cave in the wild and living a life of eating raw meat and drinking blood. That was the darkest and most humiliating time in Muzan Muzan's life. At that time, Muzan Muzan Muzan didn't even dare to step into the town. He could only survive in the wilderness like a wounded beast, fearing that Jigoku Yoshiichi would suddenly appear and completely destroy him. That memory was an eternal pain for Muzan Kibutsuji. A trace of cruelty flashed in Muzan Kibutsuji's eyes, and he conveyed an urgent summons to the waxing moons through blood connection. Feeling his call, powerful waxing moons such as Akaza, Hantengu, and Yuhu came from different directions. Their figures quickly shuttled through the night, carrying a murderous atmosphere, as if foreshadowing the coming storm. Muzan Kibutsuji stood by the window, overlooking the night outside the window. His state of mind had changed, and Muzan Kibutsuji was not going to continue playing cat and mouse games with the Demon Slayer Corps. He was ready to take action to let the Demon Slayer Corps understand what kind of existence they were facing. While planning, the figure of Yun Xi suddenly appeared in Muzan Kibutsuji's mind. The words that the new girl who joined the demon clan had said, now seemed to have come true one by one. Muzan Kibutsuji realized that Yun Xi might be able to play an unexpected role in his plan. So, he decided to give Yun Xi a chance, a chance to prove his worth. Muzan Kibutsuji was going to promote Yun Xi to Upper Six to fill the vacancy left by the death of Jifu Taro. "Miss Shinobu, why are you collecting these ashes?" After completing the maintenance of the black and white rose, Lin Yi found that Shinobu Kocho was squatting on the ground and took out a small brush to collect the remains of the dead demons on the ground. Hearing Lin Yi's voice, Shinobu Kocho raised her head and explained with a smile: "This is what Miss Tamayo asked. The potion you used before was made from the remains of demons as raw materials." The remains of the upper demons have immeasurable research value for researchers like Tamayo. Because among all the evil ghosts, the blood concentration of the waxing moon is the highest, and it is the closest to Muzan Kibutsuji.
In comparison, although the waning moon is also one of the twelve demon moons, the blood concentration of the waning moon is much inferior, and it cannot be compared with the waning moon at all. This difference is particularly evident in their remains after death. Although the color of the remains of the waning demons is deeper than that of ordinary demons, there is not much difference overall. However, the remains of the waning demons are a different picture. Their surface not only presents a deep black, but also reveals a hint of blood red. This interweaving of blood red and black seems to tell the strength and cruelty of the waning demons in their lifetime. "Let me help." Seeing this, Lin Yi took the initiative to offer assistance. Lin Yi has a deeper understanding of the power of the potion than anyone else. Without the help of the potion, even if Lin Yi can finally defeat Jifu Taro, it will never be so easy. However, the production of [Bloodline Inhibitor] is extremely difficult. To make this potion, evil ghosts of the level of the Twelve Demon Moons must be used as raw materials. The materials of ordinary ghosts cannot meet the requirements at all. This is also the reason why the Demon Slayer Corps rarely uses this potion. There is no way. Ordinary evil ghosts cannot use it. If they use it on the waxing moon, they will die. Over time, everyone regards it as a chicken rib. As the light in the sky gradually brightens, the hustle and bustle of Taikoo City gradually wakes up. The city in the early morning seems to have washed away the silence of the night. The vendors began to set up early stalls busily. The smoke from cooking curled up, and the air was filled with the tempting aroma of various foods, stimulating people's taste buds. The slums have also regained their vitality. Although life is hard, the lower-class people still hold hope and start to get busy for the new day. They greeted each other, exchanged trivial matters of life, and their faces were filled with tenacious and optimistic smiles. On this quiet morning, no one knew what happened in the dilapidated mansion last night. Lin Yi and Shinobu Kocho arrived at Tamayo's clinic with the collected ashes. Lin Yi knocked on the door twice, and soon there was a voice from inside. Yushiro, who opened the door, looked a little complicated when he saw the two. He pursed his lips and seemed to want to say something, but finally turned around and shouted into the house to inform Tamayo of their arrival. Tamayo walked out of the house with a gentle smile on her face, giving people a feeling of spring breeze. She looked at Lin Yi and Shinobu Kocho and asked with concern: "Welcome back, how is it, is there any danger on this trip?" Shinobu Kocho smiled and didn't explain too much. She took out a wooden box filled with ashes from the sleeve of her kimono, handed it to Tamayo and said, "Here, these are the materials we collected. We should be able to make a lot of new medicines." "Sorry for the trouble. I'm worried about not having enough materials recently. You guys are really a timely help." Tamayo looked at the wooden box handed over by Kocho Shinobu with gratitude. For the experimenters, the biggest worry is not having enough raw materials to carry out research.
