On the other side, Tanjiro and others on the Infinite Train finally discovered the true identity of Nightmare, one of the Lower Moons. In the end, Tanjiro used the powerful move "Fire God Kagura·Bikuroten" to gather all his strength, cut the train in one blow, and completely defeated Nightmare. This blow not only cut off the body of the train, but also cut off Nightmare's vitality, causing him to die. With the death of Nightmare, the train began to shake violently, as if a wounded beast was struggling to death. The friction between the rails and the wheels was sharp and piercing, and the entire train seemed to be able to run off the track at any time and fall into the abyss. Fortunately, the passengers on the train were still immersed in Nightmare's blood demon art at this time, and they were not aware of the danger outside, otherwise they would inevitably fall into extreme panic and fear when they saw this scene. Just as the members of the Demon Slayer Corps were ready to step forward and rescue the ordinary people in the train, suddenly, a blazing flame gushed out from the window on the side of the train and rushed straight into the sky. This flame was like a giant dragon circling in the air, making a rumbling sound, so that the train that was about to run off the track was pulled back by it and returned to the track steadily. Under the illumination of the flame, the body of the train was shining, as if it was given new life. Those originally cold and hard metals, wrapped in flames, actually revealed a warm and soft feeling.
As the flames gradually dissipated, the shaking of the train slowly stabilized, as if everything had returned to peace and order. A minute later, Rengoku Kyojuro carried the unconscious Tanjiro and walked down from the Infinite Train with Agatsuma Zenitsu and others. On Rengoku Kyojuro's forehead, a flame-shaped pattern appeared. "Is everyone okay?" After meeting up with Lin Yi and his group, Rengoku Kyojuro's eyes swept over everyone with deep concern. Fuzukawa Shiya was lying on a stretcher. Although he was wrapped in bandages, his face showed a nonchalant expression. For him, as long as he is alive, he has earned it. And Kocho Shinobu, although her physical condition is worrying, her mental state is surprisingly good. Since she avenged her sister, Kocho Shinobu's depression seems to have been completely released. Her smile now gives people a feeling of being bathed in spring breeze, which is completely different from the forced smile before. At the same time, Ubuyashiki Yoya, who was far away at the headquarters of the Demon Slayer Corps, also got the news. Upon learning that two more people were killed in the waxing moon, Ubuyashiki Yoya couldn't keep calm, and his clenched fists revealed his excitement. This victory is not only an opportunity to boost morale for the Demon Slayer Corps, but also a key turning point that changed the entire battle situation. For this reason, he ordered a grand celebration banquet to be prepared for the returning heroes, so that every team member could feel the hard-earned glory and joy. Ubuyashiki Yoya did not immerse himself in the joy of victory. He clearly realized that after this battle, the power comparison between the Demon Slayer Corps and Muzan Kibutsuji had undergone earth-shaking changes. Now, among the twelve demon moons under Muzan Kibutsuji, the lower moon has been completely wiped out, and the upper moon has also lost three warriors, which is undoubtedly a heavy blow to the evil demon camp. As for Yun Xi, who joined the battle later, Ubuyashiki Yoya did not regard her as a big threat. In his opinion, Yun Xi was more like a character that Muzan Kibutsuji casually recruited in a panic to make up for the losses. He began to formulate a detailed strategic plan, ready to use this once-in-a-lifetime opportunity to completely eradicate Muzan Kibutsuji, the evil demon leader who was causing trouble to the world.
After going through hardships, the group finally returned to the base of the Demon Slayer Corps. In the Butterfly House, the atmosphere suddenly became tense and busy, and a silent battle was started here. The wounded were carefully placed on the beds, their faces were pale, and they were wrapped in bandages, revealing an indescribable fatigue and pain. The medical staff quickly and orderly surrounded them for preliminary examinations and treatment. Although the Butterfly House is equipped with fairly modern medical resources, the medical level is still limited in this era. Especially in the absence of penicillin, the risk of wound infection is extremely high. Once infected, the consequences will be disastrous. Therefore, everyone is on edge and dare not slack off. The medical staff have clear division of labor. Some are responsible for cleaning the wound, some are responsible for bandaging and fixing, and some are responsible for dispensing drugs. Fortunately, Lin Yi was well prepared. He brought a lot of antibiotics into this derivative world. In this era, since bacteria have not yet developed tolerance to antibiotics, although the number of antibiotics brought by Lin Yi is not large, it is enough to provide effective treatment for everyone. In the ward, Lin Yi was sitting in front of the bed and peeling apples for Butterfly Shinobu. Shinobu Kocho lay quietly on the bed, her face slightly pale. She took out a brass key from her chest and handed it to Lin Yi: "Mr. Lin, this is the key to the laboratory. I may not need it in the future, so I'll give it to you." Lin Yi took the key, looked at Shinobu Kocho's slightly tired face, nodded, and said: "Take good care of your injuries, and leave the rest to me." [You get the 'laboratory key' and the right to use the warehouse. ] After killing Douma to avenge her sister, Shinobu Kocho seemed to have undergone some subtle changes. In her eyes, life and death and hatred are like passing clouds and smoke, fleeting in an instant. Kanao stood beside the bed, gently and carefully changing the bandage on Shinobu Kocho's head. As the bloody bandage was slowly removed, Shinobu Kocho's empty left eye was exposed, and Kanao's movements became more cautious. While changing the medicine, Lin Yi handed Shinobu Kocho a delicate little box. Shinobu Kocho took the box with doubts, and after opening it, a lifelike artificial eye came into view. This artificial eye is completely different from what she has seen before. Whether in terms of color, texture or gloss, it can almost be mistaken for the real thing. Lin Yi joked: "Girls' appearance is very important. Be careful that no one will want you when you get married later." Leaving the ward, Lin Yi came to the door of the laboratory. As the key turned, there was a slight sound, and the door opened. A strong smell of medicinal materials immediately entered Lin Yi's nose. This is a unique smell produced by the mixture of various herbs and chemical reagents. Although it was a bit pungent, Lin Yi felt inexplicably cordial and familiar. Walking into the laboratory, Lin Yi's eyes suddenly lit up. There were all kinds of high-precision instruments, from microscopes to measuring instruments, from reagent bottles to culture dishes. Looking at these instruments, Lin Yi couldn't help but sigh at the powerful supply channels of Kochi Shinobu.
You know, in this era, it is not easy to obtain these high-precision instruments, let alone gather them all in one laboratory.
