Wang Chen unexpectedly came to the world of collapse, but his system was not very reliable. He always had to do everything himself and couldn't help complaining: Tongbao, what use do I need you for?

System: Host, why don't you imagine the best moment you can create in this world?

Wang Chen began to fantasize, fantasizing about dominating destiny, fantasizing about changing tragedy and reviving good energy, and of course especially fantasizing about conquering one Valkyrie after another and becoming a loving family with them.

System: Very good, remember this feeling between you and the Valkyries, the happiest moment, the warmest moment, the most gentle moment, and now, host, you only need to do one thing, multiply your best feeling just now by two!

Wang Chen: What! ? Multiply by two! ?

I saw that under the effect of the system, Kiana, Raiden Mei, Bronya and... one after another Valkyries who had full favorability in the game also appeared in this world. What kind of sparks will the Valkyries on the ship and the Valkyries in this world create?

Wang Chen: Help... Help! I can't stand it, I really can't stand it anymore!!

But maybe what awaits Wang Chen is a road of no return where he can never stand up again (laugh)

There's also a lottery feature? ... Tokisaki Kurumi: "I'm not allowed to post cards here. Thank you for your cooperation!" Bai Chen: "I just got this, newbie. Does it work?" Misaka Mikoto: "Damn you, stinking seal! I told you not to post your face!" Esdeath: "Seals don't matter, Bai Chen, will you be my boyfriend?" Bai Chen: "Huh?! Do I have a bright smile?"

After traveling to the world of anime, Hikage Miyauchi obtained a magical diary. As long as he wrote in it every day, he would get rewards.

But he had read diary online before traveling, and he knew that what he wrote would most likely be seen by the heroines of this world.

As a salted fish with no ambition, Hikage Miyauchi immediately decided to be a pure fun person in this world.

"What era is it? Who still writes traditional diaries?"

"No one is really willing to write their true feelings in a diary and then be watched by countless heroines, right?"

"My mother told me that this world is very dangerous. Boys must protect their privacy when they go out, so don't think about coming to me. After all, I am a man you will never get."

As Hikage Miyauchi continued to write in his diary, an "Avengers Alliance" composed of heroines who could see Hikage Miyauchi's diary was quietly born.

They gathered together for only one purpose, that is, to find the owner of this diary and ravage him inhumanely!

For everyone who appears before me, I can choose whether to copy all their abilities to myself, or to copy the entire person and make the copy a servant who absolutely obeys me - this is the ability I have.

I have always chosen the first copy, after all, I am not interested in servants in reality.

Until one day, I suddenly discovered that I have another ability, that is, I can travel to the fantasy world through computers and mobile phones.

My name is Yotsuba Mahiro, a time traveler.

Sent to the Demonic World by an alternate-world teleportation ambassador, I became a Adjustment-Type magician of the Yotsuba clan.

Besides being born with eyes capable of replicating all forms of magic and physical techniques, perhaps my greatest supporter is my cheap mother, Yotsuba Maya.

After fifteen years in the gloomy Fourth Research Institute, my cheap mother suddenly gave him a crucial task.

"Although you're a Adjustment-Type magician of the Fourth Research Institute, you're also my child."

"So, it's also your duty to produce a worthy heir to the Yotsuba family."

It's just about carrying on the family line, a simple matter. Is the bloodline of the Ten Master Clans and the Hundred Houses enough? What if

I add your sister Miya? What if

I add the lolita from the Black Bullet world?

What if I add the assassination group from the Zelda: The Sisterhood?

What if I add a singing diva from Guilty Crown?

...

After traveling through ten worlds, he asked Maya again.

"Is that enough now? If not, I can add more!"
