Start the time travel simulator from Sky Sister!

[But Tanjiro thought about it and realized that he had seen it before, sometimes at graves, but this kind of flower withers very quickly. Sometimes they are picked on the same day and eaten as a condiment within a few hours.]

[You are stupid. I didn't expect it to exist. Tanjiro really ate it as food. This is something that Muzan tried so hard to get! ]

[You curiously asked Tanjiro about the location of the blue spider lily, and Tanjiro took you there directly. ]

[You are lucky today. There are a few blue red spider lilies on the grave. That is enough. Because they wither very quickly, you quickly start to study them.]

[Although limited, you still researched the substance in it, which seems to be similar to the knowledge you originally had. After all, you can make a potion that makes ghosts not afraid of sunlight. ]

【…】

"After all, Nezuko's blood was used for research before, so it was probably discovered at that time."

Yuu understood this instantly when he saw it.

After all, their family eats this stuff often, which is probably why Nezuko in the original work has such a special physique that she is not afraid of the sun!

【…】

[So, you planned to use this to lure Muzan into taking the bait. After all... Muzan really wanted this, right? ]

[However, this matter still needs to be announced by the Demon Slayer Corps, otherwise Muzan may not take the bait.]

[But you are very clear about Muzan's desire for a perfect creature. As long as he knows this news, he will most likely come! ]

[After all, this is something that only comes once in a thousand years. If you miss it, you may not get it again in the future. Even if he knows his own power, he should be able to overcome the fear in his heart.]

[So, you plan to start fishing. You will leave "Xie" here, and you plan to collect some medicines that will be needed to deal with Muzan later, and then go to the Demon Slayer Corps headquarters. ]

【More than a month later. 】

[You are training while searching for medicines. When you have found almost all the medicines, you plan to return to the Demon Slayer Corps, but you don't know where to go. You have no choice but to find Tamayo first. It seems that she has a way to contact the Demon Slayer Corps.]

[Tamayo was very helpful and quickly contacted the Demon Slayer Corps. You also went to the Demon Slayer Corps headquarters.]

[After you went to the headquarters, the Demon Slayer Corps were surprised that you were alive. After all, you had disappeared for a long time! ]

[They were all extremely surprised. Even Kanroji Mitsuri and Kocho Shinobu rushed to see what was going on after hearing the news about you. It seems that you still have a high position in the Demon Slayer Corps, but you have no memories. After all, you are a time traveler.]

[Shinobu Kocho thought you had lost your memory, but I want to tell you that you are the current "Poison Pillar", with extremely strong power, and can be said to be the strongest among all the pillars.]

[You immediately understood your identity, even though it didn't seem to be in the original novel... No wonder you are so powerful, it turns out you are the Poison Pillar, even though you don't understand it, just leave it as it is.]

【…】

"Inserting the identity directly turned it into a pillar??!"

"It's still the poison pillar I took earlier... but with my strength, it's still very reasonable to be in this position."

Yuu pondered.

He continued to look down.

【…】

[You also learned from Shinobu Kocho that you used to be the poison master of the Butterfly House, and that Shinobu Kocho's poisons were all improved and strengthened by you, which shows that your identity is also quite extraordinary.]

[Tell Shinobu Kocho that you want to meet your lord, Ubuyashiki Yoya, and that you have a way to lure Muzan out and kill him! ]

[Hearing your words, Kocho Shinobu was extremely shocked and her face was solemn. She took you directly to meet Ubuyashiki Yoya. ]

[Lord Ubuyashiki Yoya heard that you were back and rushed out to look for you, but he didn't expect that you had lost a lot of memories. However, you actually made a medicine that can make ghosts not afraid of sunlight...]

[And you plan to use this medicine to attract Muzan. Even Shinobu Kocho was dumbfounded by your words. After all, this is really a bit outrageous and feels a bit too reckless. After all, if Muzan brings all the upper strings, then it will be the end.]

[But you smiled, and told you not to worry, you have your own way to deal with them. ]

[Ubuyashiki Yoya thought about it for a while and nodded, saying that there was no problem, but he needed three days to prepare and the news would be released after three days.]

[He is always ready to die, so Ubuyashiki Yoya is not afraid of death. ]

[When you see Ubuyashiki Yoya agree, you begin to tell him about your plan. ]

【…】

【Three days later.】

[You have been practicing continuously for the past three days.]

[All the pillars have made their preparations and arrived at the lord's mansion. ]

[Water Pillar——Giyu Tomioka. 】

[Flame Pillar——Rengoku Kyojuro. 】

[Insect Pillar——Chocho Shinobu. 】

[Sound Column——Uzui Tengen. 】

[Love Pillar - Mitsuri Kanroji. 】

[Snake Pillar——Iguro Obanai. 】

[Rock Pillar——Goumei of the Island of Sorrow. 】

[The Wind Pillar——Buzugawa Miya. 】

[The Cloud Pillar——Tokito Muichiro. 】

[And you who became a poisonous pillar as a special case! ]

[All ten pillars...are here! !]

[Everyone stay at the Ubuyashiki residence. Gather all the members of the Ubuyashiki family here. ]

[All members of the Ubuyashiki are ready to fight to the death. The other pillars didn't even expect that the lord would agree to your seemingly reckless request! ]

【But you also have absolute confidence. 】

[Everyone stays here at night, and they only rest during the day, fearing that Muzan will come at any time.]

【A few days later. 】

[You have been practicing these days. ]

[The night weather was exceptionally cool, eight figures walked into the mansion, and all the pillars were tense.]

[The eight figures gradually emerged.]

[Upper String One——Black Death. 】

[Upper Rank Two——Douma. 】

[Upper Three - Akaza.]

[Upper String Four - Hantengu.]

[Upper String Five - Jade Pot.]

[Upper Six——Daki and Gitarou. 】

【as well as.】

[King of Ghosts——Oniwu Tsuji Muzan. 】

Chapter 34: You who have lived a long life have seen the reincarnations of your wives...

[When Shinobu Kocho saw Douma, she immediately recognized that he was definitely the guy who killed her sister! ]

[She was immediately furious! ]

[The veins on Shinobu Kocho's forehead popped out, and she wanted to go up and kill him! ]

[The other pillars are also nervous. The aura of many upper rank ones is too scary! ]

[You patted Kocho Shinobu's shoulder, looked calm and composed, and walked towards the many upper ranks.]

[The pillars looked at you, but they were extremely nervous. ]

[Your crazy training over the past year or so has improved your strength by more than a little bit. You now feel that you are very close to Tsugumi Yuichiro's strength.]

[Kizan Kibutsuji Muzan had already made preparations. When he saw you, he asked about the potion that can make ghosts not afraid of sunlight. Have you really made it? ]

[He is not stupid, but he is very eager to become a perfect creature. This desire made him come here. He cannot miss this rare opportunity that only comes once in a thousand years.]

[You laughed, took out a small glass bottle, and said frankly that this is the drug that can make ghosts not afraid of sunlight.]

[When the pillars saw you take this out, they immediately felt their scalps tingling. They had no idea what you were going to do. You just took it out so openly...!? ]

[Fuzuigawa Shima immediately called out your name, telling you to quickly keep the thing away and not let the Demon King Muzan get it.]

[But you held the small glass bottle in your left hand without caring, and drew the Sun Blade with your right hand, the red blade covered with purple viscous liquid.]

[As the "Poison Pillar", poison had already been placed on the blade, and then... the poison instantly burned with red flames! ]

[You exhale, and a transparent world opens up. Your body suddenly bursts with terrifying power, and the blade instantly cuts off the heads of Tamahune, Gitarou, Akaza, and Douma...]

[As for Kokushibo, you also chopped it, but it blocked it. ]

[You praised Kokushibo for being worthy of being Tsugikoku Yoriichi's brother. ]

[The ghost you cut will completely wither, and its body will instantly become weak and begin to disintegrate. ]

[Daki was stunned. She looked at Jifu Taro's melting body and kept shouting "brother". However, within a few seconds, she turned into blood.]

[You know, if they only cut off one of their heads, the other one would not die, but at this moment her head hasn't fallen off yet, but the other one is already dead! ? ]

[Daki suddenly felt as if a part of her body was missing.]

[Shinobu Kocho was dumbfounded as she looked at Douma. She didn't expect that her revenge would be avenged by someone else? Are the upper ranks so weak?]

[No... It's definitely not that the upper ranks are weak, but your poison is too horrible! ! ]

[Even if Muzan was infected with this poison, it would be difficult for him to survive! ]

[When Muzan Kibutsuji saw this, veins popped up on his forehead, and he lost half of his strength in one encounter! He angrily cursed at you bunch of rubbish! ]

[But your body trembled when you mocked Muzan Kibutsuji. It's not hard to see that he was also afraid, but he was just being stubborn.]

[Kizan Kibutsuji Muzan is furious and wants to tear you to pieces, but he is afraid of your strength. It seems that he can see the shadow of Yoriichi Tsugakuni in you at any time.]

[He gritted his teeth and stared at your left fist. At this moment, he was only thinking about how to get the potion.]

[He is now thinking about how to cut off your hand and then run away. ]

[You turned your head to look at Ubuyashiki Yoya and his children, and told him to start planning. ]

[I saw Ubuyashiki Yoshiya and his five children drink a bottle of potion, and Ubuyashiki Yoshiya's "disease" was instantly cured, and his children also felt that their bodies were much better than before, and they felt very strong. ]

【Muzan frowned, feeling somewhat puzzled, and asked what you were doing.】

[But you looked at the remaining Muzan, Kokushibo, Daki, and Hantengu. ]

[The dog has been crouching there for a long time, afraid that you will attack him. This guy seems to be very afraid of death. He is also a strange ghost. ]

[But if he comes into contact with your poison, he will really die, even his clones won't be able to do that, the poison will corrode all of his clones. ]

[But if he is now a clone, then it is another matter. ]

[Dakimaki is also a little scared now, after all, she always thought that her powerful brother was dead. ]

[In her own words, she is actually only slightly stronger than the lower strings, but I don’t know if she has self-awareness. ]

[Kuroshibo looks at you intently, holding a demon blade made of his own flesh and blood. ]

[Breath of the Moon·One Type Dark Moon·Palace of the Night——! ]

[He instantly slashes at you.]

[But you quickly dodged the knife, and then the blade slashed away quickly. ]

[Breath of the Moon·One Type of Dark Moon·Palace of Night! ]

[You have a strong learning ability, and you easily copied the Breath of the Moon.]

[Kuroshibo was extremely shocked. He couldn't believe that you could use the Breathing of the Moon just like that!? ]

【But he doesn't believe in evil. 】

[Then Kokushibo kept fighting with you, but not only did he fail to hurt you, but you also stole all of his Moon Breathing.]
