Su Xiaobai, who suffers from a terminal illness, is helpless and waiting to die in a cold rental house.

But what he waited for was a life simulation system. Only by completing the simulation again and again can he rely on the system to survive.

[You came to the Azure Star in the Star Iron World, became an abandoned baby, and were adopted by the Black Tower family.]

[You are a natural singer, and Heita has become your nominal sister.]

[But the disaster outside the border puts the Black Tower in imminent danger. You decide to save your sister.]

On your eighteenth birthday, you climbed a tall building, resonated with the same harmony, burned yourself, and sang your last song.

[The flames of destruction engulfed you, leaving behind only a burnt diary with the words "She is so beautiful"]

[The genius who never cries broke down in tears. To revive you, she solved the solitary wave algorithm problem. To wait for you, she achieved rejuvenation, her appearance frozen in time at her most beautiful...]

Second simulation:

[You become Fu Xuan's senior apprentice, and young Fu Xuan is very dependent on you.]

[Until the war with the Fengrao people broke out, you tried your best to convince your master and Fu Xuan to retreat together, and personally presided over the prayer for the hunting patrol...]

[The hunting arrow came crashing down on you like a meteor. You died under that arrow that could destroy everything, but you also saved her and her master.]

…

After several simulations, you recovered your health. You thought you were just a passer-by in their lives, and the system pulled you, healthy and complete, into the Star Iron World.

then……

"I, Hikigaya, am a legendary agent, a leader in the association, a master of the mysteries, one of the Five Emperors of the Ocean, and the nemesis of the weird." "I have five cousins, a sister, a childhood sweetheart, two ex-girlfriends, a lovely junior, and a beautiful colleague, but no one likes me. I'm a complete loser." The everyday and the mysteries gradually intertwine, and despite our hesitation, we continue to move forward. Cthulhu has landed in New York, and the legendary agent Altria has disappeared... This era needs heroes. "...Stay sane, and follow me into madness." Hikigaya lit a cigarette expressionlessly, put on his sunglasses, and flashed his ID [White Robe Anzai]

Chen Chu woke up from his dream and found himself in the world of Honkai Impact 3rd. Even though he hadn't completed all the storylines, the heroes before him seemed a little different from what he remembered?!

Mebius: "At least this time, you must survive..."

Kevin: "Compared to the inscription of salvation that he earned with his life, I am not worthy."

Aponia: "This is God's guidance. My Lord will surely lead us out of this haze."

Alicia: "If I could do it all over again, I wouldn't let you bear this alone!"

…

Chen Chu: "Although I am very touched, but what are you talking about?"

"But...carrying her dreams and hopes, I believe that humanity will defeat the Honkai!"

After getting killed by my yandere little sister, I am reborn in an RPG world. Moreover, it is the RPG world I programmed and wrote the script for. As the author of the game, I must definitely be omniscient and omnipotent… but wait? Why am I born as a baby girl? Hey, that’s not how the script goes! Is this a mistake? I am a man!

"What? The Cerulean Water Gym is the weakest gym in Kanto? Gym badges are free? Is that even possible? I'll go challenge it right away."

However, when the challengers who had believed the rumors arrived at the Cerulean Gym, they were so shocked by what they saw that they were speechless.

Inside the gym, Articuno soared through the sky, Suicune leaped across the water, Mega Gyarados swam freely, and Milotic's colorful scales shone beautifully in the sunlight...

"Holy crap!! The Cerulean Gym is the weakest in Kanto? Who the hell spread this rumor?" the boy, bruised and battered from being beaten, cursed angrily.

"And what about the owners of the Cerulean Dojo? Aren't they just three pretty faces who only know how to perform underwater ballet and show off their legs? And who is this Xia?"

...

...

Are you all here to challenge the Cerulean Gym?

"Well then, welcome to the strongest Water-type Gym!"

"My name is Xiaoxia. I am the youngest of the four sisters of Cerulean City Gym. I am the champion of the Indigo League and the Orange League. I am the world's number one Water-type Pokémon Master. Please take care of me."

An unknown loophole in the long river of time brought Chen Yun, who was in the late stage of cancer, to this bizarre world.

He was unable to practice, yet he was standing at the end of practice from the very beginning.

During that strange journey, the ultimate mutation of the cancer cells in his body actually gave him immortality!

"Longevity does not mean immortality. I want to live on."

Thus, the "cancer" of this world began its journey of self-reliance...

The player arrived, and so I became the BOSS.

They call me—the Lord of Eternal Night.

Zhang Ye: "Just wait, I will completely expel them from this world, leaving not a single one alive!!!"

Player: "Wait, who provoked him again? Why is he on fire again?!"

Zhang Ye: "Version update, players all log off at midnight? Opportunity!"

Player: "Why is it so dark? Who's playing that BOSS tune over there... Buhao, my guild!"

Zhang Ye: "Want to form a professional team and start a professional competition? Absolutely not!"

Player: "Wait, which pro team got a boss in here?!"

Zhang Ye: "We need someone to hold off the player alliance for ten days? I'll do it!"

Player: "Everyone calm down, listen to me—quickly kill yourself, don't let him have his fun!"

Zhang Ye: "You can't kill me. Death and revenge are on my side. One day, I will return with my might!!!"

Player: "Quick, quick, use all the world items! This is our only chance—nice, we've finally sealed this world boss!"

[World Announcement: Season 1, "Dawn of the World," has ended and a version update will be performed. Real-time: 24 hours.]

[World Announcement: Season 2, "The Beginning of Eternal Night," has begun. 120 years have passed in the game. The seal of Eternal Night has been broken. We wish you a pleasant gaming experience.]

Player: "BYD, 'one day' means tomorrow, right? Is this game even playable anymore?!"

A player commented: "It's fun, I love playing it!"

[Pure villain][Pure evil][Dark theme][Invincible]

Kanagawa, a boy who died in despair, was reborn in the dark world of Tokyo Ghoul.

The one who saved him was that gentle ghoul sister, as gentle as moonlight.

She taught him: "We only eat unclaimed corpses. We must live tenaciously like spiders."

However, the CCG's ruthless pursuit completely shattered this small happiness. As his sister lay dying in his arms, tears streaming down her face, she pleaded, "Xiao Chuan, eat me, live on in my place..."

Since this world is full of plunder

Then I will plunder you.

In ancient times, there was a black python, which turned into a snake after a hundred years, and turned into a dragon after a thousand years.

Three thousand years ago, the human immortal Zun Lin Hao killed countless demons, but was conspired by the rebels and besieged to death by the human.

Three thousand years later, Lin Hao was reborn on a black python, used the demon to prove his way, and opened a path to transforming a dragon against the sky.

The rating has just been released and is not yet reliable; it will likely increase later...

[Reincarnation] + [Has a partner, but no fixed female lead]

On their wedding day, their childhood sweetheart betrayed them, and their entire family was slaughtered.

He remarried a virtuous wife, rebuilt his family, but was destroyed once again.

In this life, we are but ants, dying with resentment.

When Lin Yun awoke in endless darkness, the [Reincarnation System] was activated!

It turns out that every life experience can be converted into reincarnation points, which can be used to exchange for one's [aptitude], [family background], [comprehension], and [luck] in the next life!

The former enemy is high above, and he thought that he had long since turned to dust?

Little did they know, Lin Yun, filled with boundless hatred, had already embarked on a long journey of revenge and ascension to godhood that spanned countless eras!

Mediocre talent? In my next life, I will be the empire's number one prodigy!

Humble origins? In my next life, I will be born into an immortal imperial family!

Through reincarnation, even the mayflies of the cosmos will eventually become supreme beings.
