Start the time travel simulator from Sky Sister!

"You-kun, I want to call you too!"

Ying puffed her lips and started yelling.

"I see... I'll write it to you!"

You narrowed his eyes and smiled, reaching out to touch her brown hair.

Then he wrote a string of numbers and handed it to Ying.

"Great!"

Ying also looked happy.

"Then you can also report yours?"

“I can save it too.”

You looked at Ying and spoke.

Although it is a landline, it must have a phone number and you can save it in your mobile phone.

"Okay... My home phone number is..."

Ying gave out the phone number.

You Gang saved his phone number.

【Ding--】

[The number of times you have crossed the simulator has been updated. Do you want to simulate it? 】

“Finally updated!”

"Simulate it! Continue with the new save."

Yuu spoke into the simulator.

[The last rating is A. The host can inherit three talents and then extract talents. ]

"Three..."

"Swordsmanship genius, medical saint, and resident certificate."

You spoke frankly.

As for why not choose rage?

The main thing is that I feel my strength is enough now. If I use rage, not only will my strength overflow, but it will also cause backlash.

If the disadvantages outweigh the advantages, don't choose it.

On the contrary, this "resident card" is indeed interesting, and it can solve my identity problem.

[Inheritance successful, do you want to start extracting talents? ]

"Extract."

[Extracting talents...]

【Ding--】

[Extraction successful! 】

[Currently available talents: Natural Affection (blue), Swordsmanship Genius (purple), Medical Saint (orange), Resident Certificate (blue), Perverted Harem King (blue), Taboo Sister Control (blue)]

["Perverted Harem King": You are a pervert and have the dream of becoming a harem king. ]

["Taboo sister control": having a love for one's sister that goes beyond family affection. ]

"What the hell are these two?"

"Damn, it doesn't have any substantial effect..."

You pinched a cold sweat.

He found it hard to imagine what would happen next. These two talents were in some sense quite outrageous.

This simulation is quite abstract...

calm down!

calm down!

It’s not a big problem, let’s start the simulation first.

"Start the simulation!"

You said impressively.

[Time travel simulation is starting...]

[On the first day, you traveled to the Butterfly family and became the older brother of Butterfly Kanae and Butterfly Shinobu. However, you are not biological siblings. You were picked up...]

[You found that your body had become a little smaller, and you were a little surprised, but you didn't think much about it. You helped your parents wash your sisters' clothes, but... in fact, it was to satisfy your perverted desires.]

[You often take your sisters' underwear and do some unbearable things to satisfy your own desires...]

[For example, using my sister's underwear to masturbate, putting my sister's pure white holy object close to my face to smell it, and sometimes even tasting it...]

Chapter 21: Becoming Tamayo's Master

"..."

"Do you want to start with such an explosion?"

"It's so outrageous!"

You looked at the transparent screen in front of him and couldn't help but complain.

He couldn't even think about how perverted he was in this memory.

By the way, doesn’t Qiong wash her underwear by hand every time?

I don't know what it will taste like...

cough cough...

It’s over. The memory hasn’t been sent yet and I’m about to be activated…

Qiong is so cute, I really want to...

Let’s continue watching…

【…】

[One day, by accident, Kocho Kanae saw you doing that with her panties, and she was so ashamed that she told you not to do that again.]

[But you tell Shinobu Kocho that Eki is also a normal man with his own needs. There is nothing you can do about it. This is human nature.]

[Kanae Kocho calms down and feels that she can understand you. After thinking about it for a while, she says that she will help you, but you are not allowed to tell your sister Shinobu Kocho, and this can only be done once a week.]

[Kanae Kocho started to lecture you seriously, just like a little adult.]

[You agreed to Kocho Kanae's conditions, and Kocho Kanae used her little hand, tremblingly, to help you. ]

[You let Butterfly Chanae use her mouth, but she can't believe you let her eat this kind of thing. She absolutely can't eat it! ]

[But you said that if I didn't eat it, then it wouldn't count this time, and I couldn't satisfy myself at all. ]

[Helplessly, Kocho Kanae listened to your words and forced them into her mouth. ]

【…】

[You must make Kocho Kanae swallow it all, otherwise it won’t count. ]

[When Kocho Kanae heard what you said, she had no choice but to swallow all the paste in her mouth. ]

[But afterwards, Kocho Kanae looked as if she had been greatly wronged.]

[You ruffled Butterfly Chanahui's hair and told her not to tell her parents.]

【She gave you a fierce look and said she understood. 】

[Her red eyes made you unable to help but caress her cheek lovingly and comfort her, but your gentle look made Kocho Kanae feel confused, as you had just been so excessive to her.]

【A few days passed.】

[A ghost came to your house, killed your parents, and was about to attack your two sisters. Fortunately, you rushed back and punched the ghost directly, but you didn't expect the punch to be surprisingly powerful.]

[You punched the ghost again and again until he was killed. Then you breathed a sigh of relief, looked at the two women behind you, and told them that you were late.]

[They didn't hate you for coming late, but were glad that you were okay... you were still alive in the face of the ghost. ]

[They cried in your arms. Even Kocho Kanae, who looked disgusted with you at the time, cried hard in your arms, as if she was very worried about you.]

[You rubbed their heads and comforted the two girls. ]

[Rock Pillar Haimingyu Gyomei arrived at this time, after all, he got the news that the demon had appeared, and then found that the demon had been killed. He was even more surprised when he knew that you killed it, and invited you to join the Demon Slayer Corps. ]

[But at this time, Shinobu Kocho and Kanae Kocho also wanted to join the Demon Slayer Corps, but Gyoumei Hiei said that they could die at any time in the Demon Slayer Corps, and they did not have the same strength as you, so he advised them to think carefully.]

[They are very determined to kill the demon, but seeing that they can't be persuaded, Gyoumei says that they will have to send the three of you to different trainers and train them separately.]

[Shinobu Kocho thinks it's okay, but there's something wrong with the way Kocho Kanae looks at you. It's obvious that she still remembers the agreement with you once a week.]

[You leaned close to Butterfly Kanae's ear and told Butterfly Kanae that you can make up for all the money you paid in a year.]

[Kanae Kocho's cheeks instantly turned red. She had no idea how many times she would need to do it to make up for it. She was inexplicably afraid in advance.]

[You looked at Shinobu Kocho's red eyes, rubbed her head, and told her to train well and join the Demon Slayer Corps to avenge her parents.]

[Hearing your words, Kocho Shinobu nodded with tears in her eyes, and just like that, you agreed to meet again in the final selection one year later, and Gyoumei on the Island of Sadness separated you.]

[Gyouming Yuxingming knows that you killed the ghost and thinks that you are very powerful, so he asks which trainer you plan to find. ]

[But you directly let Beimingyu Xingming fight with you. You know that with your strength, you can do it even without a trainer. ]

[You held a katana and had a brief duel with Gyoumei of Beiming Island, which shocked him greatly. He did not expect that you actually had the same strength as the pillars... or even stronger than the pillars. With this kind of strength, as long as you report it to the lord, it will be no problem for you to make an exception and become a member of the Demon Slayer Corps.]

[Tell Gyoumei Mizuki that you have your own things to do. You will go to Fujiyama to participate in the final selection in a year, but I hope that your two sisters will receive the best treatment this year. If anything goes wrong, you will become the enemy of the Demon Slayer Corps.]

[Beimingyu Xingming immediately understood your determination and swore to agree to your request. After all, he had seen how powerful you were and understood that you didn't need any training at all. However, he was also somewhat curious about what you wanted to do.]

[But you didn't tell him that you now not only have powerful swordsmanship, but also have rich knowledge of medicine. ]

[You plan to find Tamayo to make some potions to fight against ghosts. ]

【…】

"So you're going to look for Tamayo..."

"After all, I have the memory of medicine, so it is normal for me to go to Tamayo. Besides, Yushiro should not be with Tamayo during this period of time."

“It’s indeed a good choice…”

You murmured.

Now I don’t have many choices. The only two options are killing ghosts and studying medicine.

After all, you can't become a ghost, right?

If you are exposed to sunlight, you will die. With such a big weakness, only a fool would think it is a ghost.

【…】

【A few days later.】

[You came to Tamayo and quickly made a potion that could turn ghosts back into humans, turning Tamayo back into a human.]

[Tamayo didn't expect that there is such a powerful medical expert like you in the world. She was extremely amazed. After all, you are a human being and you look like you are only in your teens.]

[Tell Tamayo that these are just trivial matters. If you are interested, I can learn from you.]

[Tamayo became your apprentice and studied medicine with you. She admired you more and more.]

[When you lived with Tamayo, you did a lot of perverted things, often drugging her and letting her do whatever she wanted when she was asleep, and Tamayo didn't notice it many times.]

[One time, the dose you gave Tamayo was not enough, or maybe Tamayo's body developed resistance, so she woke up during the process.]

[She couldn't move, with tears in her eyes, just looking at you. ]

[Repeat the action at this point...]
