(Transformation, apocalypse, rebirth, invincibility, pure love, the boss helps the heroine evolve and upgrade)

Global catastrophe, all things evolve, monsters run rampant, civilization is in danger.

In this age of monsters and famine, there is no longer any trust between people, and the only way out is endless killing and plundering.

However, even in such a dangerous world, my awakened supernatural power turned out to be - the congenital pregnancy body!

Evolve into the most perfect woman, and you can perfectly pass on all the abilities and skills of your spouse to the next generation! Although your physique has been enhanced, it is only slightly stronger than a normal person. If you want to get new skills, you must kill monsters and level up, but I don’t have any skills!

And this is not the worst thing...

"Hey, hey! Stop pulling my hair! What the hell do you want, you pervert!"

"Damn woman! I don't know how many people will die in your hands in the future! Rather than letting you grow into a demon, it's better for you to become my slave!"

"Why?!"

"Isn't this right? Author, what are you doing!?"

"Shouldn't I be the protagonist of this book?"

[No system + single female lead + sister-brother relationship + body travel + marriage first, love later]

Lin Yi traveled to a parallel world with more women than men.

Before he started to enjoy his life of playing sloppy, his whole family urged him to get married, and even arranged a blind date for him.

Please, isn’t it too early to get married?

It seems that even if he traveled through time, he can’t escape the fate of being urged to get married.

In desperation, he went to meet this beautiful woman his father had mentioned.

...

Lin Yi would never have thought that his blind date would be her.

Although they had only met a few times, they still recognized each other.

"Since it's you, let's go get the certificate."

"!!!"

"Isn't it a bit too fast!"

...

As they continued to live together, Lin Yi began to find that he seemed more and more like a younger brother being spoiled by this "sister" who was six years older than him.

"Little guy, come here."

"No."

"Come here, I can't sleep, I want to hold you to sleep."
