Start the time travel simulator from Sky Sister!

[Your medical technology in recent years is quite terrifying! ]

【…】

"I am really impressed by this. Muzan's doom is coming..."

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

Twenty compound medicines...

Even without the sunlight, you can kill Muzan, right?

The compound medicine in the original book almost killed Muzan. To be honest, twenty kinds are too exaggerated.

There is not a single demon in Demon Slayer World that can resist this potion.

In this case, after Muzan has just decomposed one, there are still nineteen. I really don’t dare to imagine that scene.

If he really penetrates into Muzan's body, it will definitely break his defense.

How terrifying! How terrifying!

【…】

[Tamayo plans to make a few more of this type of potion as a backup, and must ensure that Muzan is killed. ]

[Only then did you realize that Tamayo's hatred for Muzan was not just ordinary, it had reached a terrifying level.]

[Of course, you support her very much, just like you support your wife.]

[Tamayo couldn't help but kiss your cheek, looking at your determined eyes and flawless muscles that supported her, she felt inexplicably enchanted. ]

[She knows very well that she has fallen in love with you...]

【…】

【The happy day is fleeting. 】

[Nezuko has now regained her consciousness. When she thinks of what you did to her, her cheeks turn red and she starts to ask you if you are responsible.]

[That fierce look...it's like she'll bite your roots off if you dare say no.]

[You promised her, after all, it’s a good thing. ]

[Nezuko is very happy because she actually likes you too, although she doesn’t understand why…]

[Maybe it's love that grows over time? Or maybe it's your looks and figure? ]

[However, the most likely reason is... because you saved her and allowed her to turn back into a human again.]

[You said, this way we are a family. ]

[Nezuko's heart is once again filled with your sweetness, and is extremely fulfilled. ]

[She also fell.]

[Nezuko enjoys the family happiness you give her, and only hopes that you will not stop for a second. ]

[When her love overflows, she says she wants to have a baby for you. ]

[She said that her mother had given birth to six children, so she could also work hard.]

[Women who are filled with love always make decisions without considering the consequences. ]

[Tamayo discovered your relationship through the crack in the door, and she covered her mouth with tears, feeling a heart-wrenching pain.]

[She originally felt a little inferior in front of you because she was once a married woman, but when she really felt that she was going to lose you, she felt even more uncomfortable.]

[You noticed something was wrong with Tamayo, soothed the tired Nezuko to sleep, and walked out of the room to look at Tamayo with tears in her eyes.]

[You don't want to say more, you hold her in your arms and caress her body. ]

【Tamayo asks if you dislike her. 】

[You shook your head, then hugged her to the sofa in the living room, proving with your actions that you didn't dislike her.]

【The air is filled with the smell of happiness. 】

【…】

Chapter 16: Learn medicine and taste the world's delicacies

【A few days later. 】

[These days, you get along well with them. Nezuko and Tamayo also know about your relationship with each other, but they don't despise it. ]

[Tanjiro has also returned. He is very happy to find that Nezuko has recovered her memory, and invites you to go to the Butterfly House together. This is also what the lord wants. ]

[You and Tamayo also agreed, and you didn't want Shinobu Kocho to die like this. ]

[You followed Tanjiro to the Butterfly House, and Kocho Shinobu specially set up a laboratory for you. When she learned that you had developed 20 kinds of compound poisons targeting Muzan, Kocho Shinobu was extremely surprised. It was hard to imagine that this was something that humans could do.]

[Tell Shinobu Kocho that this poison can also be used on the upper ranks. Shinobu Kocho happens to be a poison-specialized insect pillar, so she can cooperate with you and combine the toxin developed by Shinobu Kocho with the compound potion you developed.]

[Tell Shinobu Kocho that you can specifically select a group of Demon Slayer Corps members who are as weak as her, and then attack them with poison. After all, as long as your poison can be injected into the body of a demon, the demon will surely die!]

[When Shinobu Kocho heard what you said, she immediately felt that it was a good idea. After all, using poison to attack is much easier than chopping off a demon's head.]

[Soon, she began to deploy such a special force, called the "Poison Killing Squad."]

[And you start to counsel Kocho Shinobu, never joke about your own life, you will help her. ]

【…】

Saw this scene.

Yuu thought back to the time when he simulated painting a pie for Shinobu Kocho, but Shinobu Kocho died before she could even eat it.

"I hope this time I won't make any big promises."

You complained silently in his heart.

However, conquering Shinobu Kocho is also a very difficult task.

At a time like this... Shinobu Kocho is still thinking about revenge for her sister, right?

【…】

[Since Tanjiro and Nezuko also live in the Butterfly House, Nezuko often comes to see you, and she and Tamayo are also in harmony. ]

[Daki is well treated by you, and sometimes you even give her some drugs to make things more interesting. Now she calls you "master" and doesn't even dare to think of anything that goes against your will.]

[You are very satisfied with Daki's appearance. If you make her obedient, you will get candy. Otherwise, you will only suffer endless torture.]

[She lowered her head obediently, wanting your caress. ]

[You touched her head, with a smile on your face, because you sensed that all she wanted in her mind was your love.]

[But you have recently developed a lot of torturous drugs. Daki is so obedient that you are reluctant to use them on her. ]

【…】

[After a while, you heard that Tanjiro was going to the Swordsmith Village, and you immediately knew that the rest of the story was about to begin. ]

[You also planned to go to the Swordsmith Village, but it was indeed a bit cumbersome and required you to go blindfolded, so you decided to go alone. Nezuko did not go because she had become a human and had no fighting ability.]

[You met the Love Pillar Kanroji Mitsuri here, and you began to praise her constantly. After all, in your heart, the Love Pillar was really beautiful, especially her chest, which was particularly tempting. ]

[Kanroji Mitsuri blushed and sweated when you praised her, because she thought you were cute the first time she saw you.]

[After all, Kanroji Mitsuri was rejected on a blind date because of her great strength and strange hair color, which was a big blow to her, and she still has a bit of low self-esteem.]

[Under your compliments, she is almost completely overwhelmed, hugs you tightly, and plans to treat you to food. ]

[As a pillar, she is quite wealthy. She ordered a large table at a time, and there are only two of you. Kanroji Mitsuri actually has a big appetite. Knowing this, you kept adding more dishes to her dishes, peeling shrimps, and giving her all the delicious food.]

[And tell her to finish eating it~]

[She is so happy under your love and care, and feels that you are a good family man. ]

[But you're not a particularly good person either. When you poured her water, you put something in her cup.]

[She felt dizzy after drinking it, and then fell into your arms.]

[This medicine is specially made for Mitsuri Kanroji. ]

【…】

"what……?"

"If you learn medicine, won't you be afraid of having no women?"

You was stunned.

This operation is really unique. How could I do such a thing?

As expected... in this cruel world, it is normal for one's psychology to gradually become distorted after gaining power.

In fact, the reason why ghosts exist is simply because of human desires.

Ghosts... to be honest, they are the most afraid of death.

Moreover, there are not too many constraints in this world, and the superiority and inferiority are determined by strength.

In other words, most worlds are like this, even the anime world we are in now.

【…】

[Mitsuri Kanroji's whole body is hot, and she kisses you out of biological instinct, and after throwing you down, she starts to pull off your clothes.]

[She runs her tongue over your neck, as if tasting some delicious food, breathing heavily, filled with love.]

[She couldn't hold back her body's urges and began to caress your refined body.]

【…】

[The next day.]

[After waking up, Kanroji Mitsuri covered her mouth while looking at her naked body. She couldn't believe that she had actually done such a thing, but the scene in her mind was still vivid. What happened to her yesterday? ]

[She felt the pain, saying sorry, tears unconsciously falling from the corners of her eyes, and began to cry softly.]

[You heard the sobbing sound and looked at Kanroji Mitsuri beside you, but you hugged her in your arms. ]

[Mitsuri Kanroji felt your warm embrace, leaning into your arms, and seemed to have recovered a little. ]

[Tell her to get married after killing the ghost.]

[When Kanroji Mitsuri heard you take responsibility, her heart immediately changed from aggrieved to pleasantly surprised, and she looked at your gentle face.]

[She was so innocent that she had no idea that this was an accident that you had carefully planned.]

【…】

"Is this how you play...?"

"I was even a little worried that I would be chopped by a hatchet..."

You couldn't help but complain as he looked at the simulation content.

This time I set a trap for her, it was really amazing.

【…】

[You and Kanroji Mitsuri have been developing a relationship for a while, and suddenly there was a commotion not far away, and you knew that the Upper Rank had arrived.]

[But you have already made preparations in advance and gave Tanjiro the poison specifically for upper-ranks, so you are not worried. You comforted Mitsuri Kanroji beside you with your words, letting her feel at ease.]

[After a while, the loud noise in the distance disappeared, and it seemed to be over. ]

[I have my own poison, so I can't lose even if I think this way. 】

[And this is indeed the case. You and Kanroji Mitsuri put your clothes in order.]

[Soon, Tanjiro and his men came back. He didn't even have any serious injuries. As long as the potion was applied to the Nichirin Sword, it could be said that even an upper rank enemy could be killed with one kill.]

[Tanjiro was immediately impressed by your demon-killing poison and was extremely shocked.]

[You don't care about this kind of thing at all. After all, the medicine given to Tanjiro is not the strongest poison you made. ]

"Good good..."
