Start the time travel simulator from Sky Sister!

[Under your threat, Kuizhi tied up the remaining two women and one man, and then you tied up Kuizhi as well.]

[But there was also a baby named "Six Tai". After they were tied up, you ate them in front of them. You only felt almost full after adding an appetizer.]

[They were crying so hard, you told them to shut up, or I would eat them too, and then the crying would stop.]

[Then, the only one who was not tied up was Tanjiro. You held back a bit of force in your punch just now, but he still fainted. You were surprised at how weak Tanjiro was before he left the Novice Village. Then... you poured the water on the table on his face.]

[Tanjiro was instantly awakened by the choking. He found that Rokuta was also dead. He immediately cried and looked at you angrily, as if he was going to fight you to the death.]

[But you don't care at all. After all, you are a villain. You can use all the means you can! You don't need to care about the rules and morals that restrict you! ]

[You used the person behind you to threaten Tanjiro. You grabbed Aoi's neck and forced her to perform the Fire God Dance in front of you, or you would kill the person behind her immediately.]

[Tanjiro gnashed his teeth, but he could only teach the Fire God Dance. He had no choice now.]

[You look at the dance carefully, and let Tanjiro dance three times. With your strong swordsmanship talent and your own swordsmanship foundation, you seem to understand the essence of it. ]

[After eating two people, you have a strange feeling. Your blood pierces your skin and flows out from your fingertips to become a blood-colored long sword. This is you, your blood demon art, blood sword.]

【Shua——! 】

[I saw you also start swinging your blade, but flames seemed to float on the blood sword! This is obviously the Breathing of the Sun! ]

[You may even be a little surprised at your own learning speed...]

[But this means that Tanjiro is useless. As a villain who understands the importance of finishing off the opponent, he naturally cannot spare the opponent's life. He uses the Sun Breathing that he just learned to kill Tanjiro directly. ]

[Then there are three women and one man tied up in front of him. The women are his mother Aoi, Nezuko, and Hanako. The man seems to be called Takeo.]

[The four of them kept crying, but they didn't dare to make any sound.]

[Aoi begs you to let them go...]

[But at this moment, you have an inexplicable impulse towards the three girls. You lick the corners of your mouth and feel extremely excited.]

[But the man next to him was useless and a bit conspicuous, so he killed the last man from the Kamado family as well.]

【Then, you carried the three tied-up women to the bed.】

【…】

Chapter 5: Becoming the Lower Moon

"Am I so crazy now that I've become a ghost?"

"No! This is definitely because of talent!"

You was also stunned when he saw the series of texts that could not pass the review.

Just turn into a ghost and fight three of them at once!

So fierce!

【…】

[Nezuko and Hanako fainted, and only Aoi was able to hold on. She was still begging for mercy, hoping that you would let her daughter go.]

[At this time, Muzan's voice echoed in your ears, and Mingnu will transfer you back in five minutes. ]

[You ask Kuizhi, who is still awake, to tidy up their clothes within five minutes.]

【Five minutes later.】

[You come to the Infinite Castle again, but this time there are three more girls: Aoi, Nezuko, and Hanako. ]

[At this time, Nezuko and Hanako were lying directly on the ground of the Infinite Castle. Nezuko seemed to feel the changes around her and sat up tremblingly. ]

[He will praise you for doing a good job and then ask you what you think should be done next.]

[After all, although Muzan has your memories, he doesn't think the way a time traveler does. He wants to make the most of you.]

[Tell Muzan that if you want to completely overcome the sun, you still need Tamayo's help if you don't rely on the blue spider lily.]

[But Muzan frowned, because Tamayo was a traitor, and he didn't think Tamayo would help him. ]

[But you said: "Bonds are the biggest weakness of human hearts. Doesn't she have an attendant by her side? His name is Yushiro... You can use this to threaten her. Torture him in front of Tamayo. Tamayo is so gentle that she will always feel guilty."]

[When Muzan heard what you said, he burst into laughter. He didn’t expect that the person in front of him could come up with such a great idea. He said to you: “You are quite suitable to be a ghost! You, you are simply a devil!”]

[You look at Aoi and the other two, then turn around and tell Muzan that you only need to give them a small amount of blood, and then lock them up for Tamayo's experiments. It's okay if you don't feed them.]

【Muzan also nodded. Based on your memory, he more or less understood what you wanted to do. It was nothing more than to see if they would regain their sanity on their own or cut off contact with Muzan.】

【Then, you asked Muzan for the reward for becoming a Lower Moon.】

[Muzan will directly tell you the positions of other lower ranks, and ask you which lower rank you want to challenge. Once you have challenged him, he will give up his position to you.]

[You also expected that it would not be so easy, so you directly said that you wanted to challenge the lower moon named "Rui" at "Nada Spider Mountain".]

[But it's already daybreak outside, so he can't go to "Nada Spider Mountain" for now. There's nothing he can do about it. After all, I heard that "Ti" doesn't go out during the day and lives in a shabby house, which is not enough for you two to build.]

[Muzan asked if you wanted to summon Rui using Naruto's ability, and you were not in a hurry right now, so you shook your head. ]

[Muzan asks you again if you will help him catch Tamayo back. ]

[You rejected Muzan again, complaining that Muzan has so many subordinates. You can't let him do everything! Isn't he just a tool? ]

[But Muzan actually wanted you to go with Akaza. Since you didn't want to go, he let Akaza go alone. After all, he still values ​​himself becoming a perfect creature. 】

[Before Tamayo came, Muzan had injected a small amount of his own blood into the three girls, Aoi, Nezuko, and Hanako, and specially prepared a prison for them in the Infinite Castle. You will be the one guarding it.]

[Because of your special identity, Muzan took a fancy to you, and when you were on guard, he even asked the upper rank to come and teach you. ]

[But you are surprised! The person who came is actually Upper String One——Kuroshibo! ]

[Kokushibo was a little confused at first. Why would Muzan let him teach a guy who just became a demon? 】

[But when he fought you, he was extremely shocked. He didn't expect you to know the Sun Breathing! ]

[This reminded Kokushibo of his brother, and he instantly became excited. He accidentally used too much strength and almost beat you to death. Even his own recovery ability couldn't keep up.]

[Well, after all, your strength is far inferior to that of Kokushibo, you are still too weak! ]

[After this battle, you realized how weak you are. ]

[But it’s not over yet. Now that you have recovered, let Kokushibo continue to fight you. ]

【…】

[It was night before I knew it. Your Sun Breathing had improved rapidly. You figured out the thirteenth form of Sun Breathing through memory and learned a new blood demon technique. Even Kokushibo could not help but sigh that he saw the shadow of Yoriichi in you.]

【…】

"Is the purple talent for swordsmanship so strong? Is it comparable to that monster Yunyi?"

"What about the orange, red, and gold talents at the back?"

"But... I haven't opened the stripes and the transparent world yet. I'm still a long way from that."

You stroked his chin in thought.

I have to say, it really gets more exciting the more I watch it!

But what’s the use of having such powerful power in this everyday world?

Well...if I could have a Sharingan, it would be quite useful.

I don’t know if there will be any strange things happening behind this seemingly ordinary and mundane world.

For example, some everyday superpower world or everyday ghost world...

Maybe these things exist, but many people don't know about them.

As I was thinking, I continued reading.

【…】

[It was dark, and you asked Naruto to send you to "Nada Spider Mountain". It seemed that because of the reasons that Muzan had told you in advance, Rui was already waiting for you. ]

[Behind Lei, there stood his so-called "family", but... those family members were just puppets bound by fear. ]

[You used the Blood Demon Art: Blood Sword on Rui, forcing him to surrender.]

[But it is obvious that he will not surrender. It seems that Muzan told him something. He did not underestimate you for using blood demon arts at the beginning. ]

[Red, knife-sharp threads are rushing towards you. Your blood sword instantly catches fire and you use the Breathing of the Sun to easily cut through the threads. This is normal... After all, you are a swordsmanship genius!]

[He keeps attacking you with those threads, but they are constantly cut off by the blood sword you use.]

[You originally wanted to improve yourself with this kind of frequent output, but you found that your attack was far inferior to that of Kokushibo, and you lost interest. ]

[You once again use the blood demon technique you learned when fighting Kokushibo, the Ten Thousand Blood Sword! ]

[You sprinkled blood into the air, and countless blood swords gathered in the air, shooting towards Lei one after another! ]

[Lower Fifth's Rui was instantly nailed to the ground, completely unable to move. You won easily.]

[Obviously, your strength has surpassed the lower string, but I'm afraid you're still a long way from the upper string. ]

[You looked at the "family members" of Lei behind you. They were all shocked. They didn't expect that such a powerful Lei could be killed! ! ]

[You leisurely scanned these tired family members, and found a few that suited your taste, so you could keep them... You didn't intend to let go of the others.]

【…】

[In the end, only three ghosts were left after you killed them. Two of them played the role of Lei's sisters, and one played the role of his mother. They were all given powerful powers by Lei.]

[They kneel before you, having recognized the disparity in power, and are planning to join your army.]

[You couldn't help it, so you killed them right there and then without saying anything...]

Chapter 6 Good Morning

"This……"

"I'm really envious, even though it's me..."

You was completely confused.

This "Bull Charge" is worthy of being a purple talent, it's really fucking powerful!

In the wilderness... he was executed on the spot?

But...it's still of no practical use, and doesn't bring much improvement to myself.

It's really a damn stud talent. Next time I hope to get an improvement that can be of actual use.

You kept complaining in his heart, but his strength had indeed increased significantly after becoming a demon this time.

He still had to rely on his eloquence and his identity as a time traveler to convince Muzan. Judging from the current situation, Muzan still trusts himself very much.

【…】

[It was almost dawn, and the three girls took you to where they originally lived. They all hid in the house during the day.]

【You look at them and decide to name them. 】

[The actress who played the role of the eldest sister was named "Qi" because of her bangs.]

[The second sister is played by Zhongfen, named "Fen". ]

[The actress who plays the mother has side bangs, so it’s called “side bangs”. ]

[You won't be as strict with them as you are tired, and they won't turn into white-haired people at any time, but you still like their white-haired style...]

[So, you allow them to transform back to their original form when they are not in front of you, but they must transform into their current form in front of you. After all, their strength will increase when they transform, and long-term transformation training is also good for them.]

[They found that you seemed to be easy to get along with, and they all smiled happily. They immediately felt that they had not been tortured by you in vain. The three women all unanimously decided to follow you in the future.]

[The original form of "Xie" is actually just a child with a bad temper, but when he turns into a white-haired form, he plays the role of "mother", which is really a great contrast. ]

[“Qi” and “Fen” seem to be good friends now, but you know that in the original book, “Qi” was betrayed by “Fen” and then died in the sun. ]

[You didn't put too much pressure on them. There was only one hard requirement, which was that they were not allowed to escape without permission. That was all.]

【…】

【A few days later. 】

[Because you replaced Lei, the words "lower string" also appeared in your eyes, which is equivalent to a special identity. 】

[And today, Muzan used Mingnu to call you back to the Infinite Castle, because Tamayo had already caught you, and used the method you proposed. Yushiro was tortured by pain, and as expected, Tamayo was forced to agree to Muzan's conditions. ]
