Start the time travel simulator from Sky Sister!

Looking at the movie-like memory in my mind, it seems that this is not a simulation, but something that really happened...

"Physical strength and water breathing in the simulation..."

You murmured.

At this time, his physical strength didn't seem to be very strong.

By the way, Urokodaki seemed to have said that his one-handed water breathing was no worse than that of two-handed, right?

He seemed surprised by its power, so he could choose to give it a try.

As for physical strength...

You can definitely wait for the next simulation. You still have two simulation chances!

"Just choose two!"

He chose it directly without giving it too much thought.

Suddenly!

A stream of information entered Yu's mind and spread throughout his body.

His breathing pattern changed instantly, as if the muscle memory from the simulation was brought out.

You looked at his hands in a daze. This feeling was really strange.

“That’s amazing…”

He murmured softly.

[Host has two more simulation chances. Do you want to simulate again? ]

"Yes."

Yuu answered immediately after hearing the voice.

[Does the host enter the timeline "No. 001" of the first day of the last simulation, or does he switch timelines and locations immediately? ]

[This system will have archives for each timeline, and the host can choose by himself. 】

“I can actually choose by myself…”

Yuu thought for a moment, then said, "Then let's save 'No. 001' like this for now... and then change the save file to continue with the random one!"

After all, the initial location of the save file was an unknown small village, and it was rather troublesome to go anywhere.

It’s better to change place.

[The host can inherit one of the two talents extracted, and then extract the talent. ]

"Inherited talent...? Then it must be a swordsmanship talent! I think this is more useful."

Yuu didn't think too much about it.

[Start extracting talents...]

【Ding--】

[Extraction successful! 】

[Current talents: Natural Favorability (Blue), Swordsmanship Genius (Purple), Bull Charge (Purple), Mouth-to-mouth (Blue)]

["Bull Charge": It is difficult to suppress impulses, and the fear in your heart increases significantly. ]

【"Liao Dun": Good at speaking, easy to persuade others to go in the direction you want to develop. 】

Yuu: "..."

""Bull Charge"...???"

"Isn't this thing more powerful than "One word! Fuck!"?"

He really couldn't help but complain.

drop drop~

The phone in You's pocket suddenly rang, and needless to say it was definitely Qiong.

He turned on his phone to see what his dear sister was up to.

[06/22 22:11]

[Qiong: You, what did you just do...? ]

Qiong seemed to be testing herself.

[Yuu: Haha~ It's okay, Qiong, don't worry too much, it's just a goodnight kiss from my dear brother. ]

[Qiong: Good night... kiss? So direct... Yu, you've changed...]

You looked at the message on his phone...

Can I just say that she is worthy of being my sister?

Ever since he awakened his past memories, he has become like a different person, so it is normal that he was discovered by Qiong.

But at this time, he also knew what to do to make Qiong feel at ease.

[Yuu: Really? But, my love for Kyon won’t change…]

[Qiong: So corny...]

……

Next room.

Qiong looked at the message on her phone and her white cheeks instantly turned red.

She held the black stuffed rabbit in her arms, with the quilt between her legs, feeling extremely ashamed.

"When did Yuu become so cheesy... idiot..."

Qiong grumbled softly.

drop drop~

Yuu sent a message.

[06/22 22:12]

[You: Qiong, you are not feeling well. You should go to bed early. It is already very late today.]

Qiong looked at You's caring message and felt warm inside...

【Qiong: Got it. Good night.】

【You: Good night. 】

She turned off her phone and put it aside, but she felt inexplicably touched in her heart.

Qiong covered his chest, breathing heavily, and closed his eyes. In his mind, the doting face of You kept flashing.

"Yu...Yu~"

Chapter 4 simulates again and starts in Infinite City

After You coaxed Qiong to sleep, he felt relieved.

"Start simulation."

He continued his time-travel simulation.

[Time travel simulation is starting...]

[On the first day, you traveled to the Infinite Castle and met Muzan Kibutsuji...]

Yuu: "?!"

"no……"

"Even if I can breathe water, I can't do this..."

Yuu looked at the first sentence on the screen.

He was sweating profusely in an instant. This was definitely the start of hell.

[Muzan was very surprised that you came in without his permission. He was immediately filled with murderous intent, and obviously wanted to kill you.]

[You quickly say Muzan's name, and then say that you have a way to make Muzan a perfect creature! ]

[Muzan frowned slightly, and became slightly interested in you. He told you that if you become a ghost, he will believe you... otherwise you will die! ]

[But how can you not know Muzan's thoughts? If you become a demon, won't Muzan be able to steal your thoughts at will? But this is the situation... He is likely to force you to become a demon! ]

[There is no other way. In order to survive, you have to become a demon... You promised Muzan and became a demon.]

[You were forced to drink Muzan's blood, and when you turned into a demon, you felt a pain as if your whole body was reborn...]

[I don't know how long it took, but you made it through, and Muzan also received your memories. He didn't expect that you were actually a time traveler, which surprised Muzan immensely! ]

"It's over. I can't figure out who the protagonist is..."

You complained inexplicably.

Although he survived by relying on his own mouth, but Muzan absorbed his memory, so he must have been able to quickly complete the "Pillar-Destroying Blade"?

[But then Muzan burst into laughter. After all, you have become a ghost, which means you are Muzan's subordinate! You are a time traveler, which is beneficial to him! ]

[Moreover, Muzan also understood what would happen in the future. If he didn't want to die, he had to make changes in advance! ]

[Muzan tells you the timeline of this world, which is a few days before Muzan was about to turn Nezuko into a ghost, and asks you if you have any ideas that can make Muzan a perfect creature, and what your next plan is. ]

[You don't think too much about it. Since you have become Muzan's subordinate, there is nothing you can do. You said you are interested in meeting Tanjiro in advance and let him teach you the Sun Breathing. Then you can kill Tanjiro, the protagonist, for Muzan, and capture a few of their family members to study why they can overcome the sun.]

[When Muzan heard the words "Breathing of the Sun", his eyes widened, as if he had thought of something horrible. But after calming down a little, he felt that he should indeed train such a subordinate...]

[After thinking it over, Muzan is quite satisfied with your idea, so he decides to let you do it. If you do a good job, he will give you a chance to become a Lower Moon.]

[You saw that Muzan intended to promote you, and you immediately showed a confident look. Even as a demon, you want to be a demon below one and above all demons! ]

[Muzan seemed to have sensed your desire to become stronger, and a smile appeared on his lips. ]

【Afterwards, Muzan ordered Naruto to take you to a location closer to Tanjiro's family. 】

【…】

"It seems that Muzan is quite happy about the news I brought. He is in a much better mood."

"That's right. After all, I am the important person who made it possible for him to become a perfect creature. How could he not be happy?"

Yuu murmured as he analyzed.

【…】

[You suddenly appear in the dark night with heavy snow. According to my memory of the anime, the Kamado family should live in the mountains.]

[As a ghost, you feel extremely powerful at this moment, but you are a little hungry, and you know that you need to replenish your food as soon as possible. ]

[You went up the mountain...]

[After walking for a while, you see a small house, and the snow has stopped falling around it. ]

[But fortunately it is still dark, it will probably take some time before dawn. ]

[You smelled human breath, you were very hungry, so you broke into the room, waking everyone up. Without saying a word, you spotted a child and started biting him. Several children huddled in a corner, not daring to move.]

[Tanjiro ran towards you angrily, yelling "Don't hurt Asheng", and then hit you with the hoe in his hand. ]

[But a mere hoe couldn't even break your skin, and you punched Tanjiro directly in the stomach! ]

[Tanjiro's stomach acid came out after being hit by this punch, and he fell down directly. 】

[You licked the blood from the corner of your mouth. At this moment, you found that your humanity seemed to have been annihilated. Even though you ate a human being, you didn't feel uncomfortable at all. Instead, you felt extremely happy.]

【Then you looked at the boy who was slightly younger than Tanjiro, and then walked slowly towards him. 】

[A woman quickly stood in front of him and begged you. You recognized that this was Tanjiro's mother "Aoi", and then sneered and told her to tie up everyone except Tanjiro, or she would eat them now.]
