Harry Potter: Eclipse. - Chapter 11:

In the year 4 Before the New Calendar, just four years before the arrival of the Great Tomb of Nazarick, Lyle finds himself sitting by the roadside, gnawing on a piece of coarse black rye bread. His gaze is hollow, tinged with despair—he has been transported to the world of Overlord.The prospect of facing the devastating events to come chills him to the bone. In just a few years, the Great Tomb will unleash its might, razing nations and reshaping the world. Lyle foresees two grim paths ahead: perishing in the cataclysmic aftermath or surviving to live under the rule of the Sorcerer Kingdom.But as hopelessness threatens to consume him, a unique panel materializes before his eyes: Innate Ability: “Player”.Armed with the same advantage as the feared entities of Nazarick, Lyle resolves to carve his destiny. If they're all players in this grand game, why should he cower before them? The race against time begins as he seeks to grow stronger, navigate the treacherous world, and defy the fate that looms ever closer.

In the year 2025, humans awakened with the ability to summon mighty beasts—capable of destroying terrains, breaking the laws of physics, and creating wonders limited only by one's imagination.But before these blessings came a curse.An alien face appeared from nowhere and threatened all life on the planet, leading to the greatest war in human history.In the aftermath, the human race and the alien race were forced into a shaky treaty that could be broken at any time.Years later, tests for summoning abilities began for the next generation. Those who awakened low-grade summoning would be thrown to the gutters, while those who awakened higher got to join great factions after graduating from the academy.Kairos Veyl, the blank, calculating student, pulled his hand from the massive crystal pillar and stared at the large beast before him.“This kid—he just got a LEGENDARY SUMMON.”A legendary summon? The greatest class of summoning. However, with this class came a risk one would have never guessed.

My name is Zhu Fukongliang, male, 18 years old.
When I was in the second grade of middle school, I bound a [plot maintenance system].
Every time I fell asleep, I would travel to a certain character in a parallel world, and my task was to play this character and proceed with the normal main storyline.
Only later did I realize that the parallel worlds I traveled through were scientifically called [Doujin World].
This system has had a huge impact on my life.
Because I always accidentally confuse the distinction between my world and the world of my fans.
​
——For example, when I just came back from the world of [All Staff Beastization] and saw a certain nasty ghost Matsuda, I didn’t react for a while, and said directly: “Where are your cat ears and tail?”
He also took a cat stick and stuffed it into Matsuda: “Here, your favorite snack.”
Police Academy Five: ? !
Matsuda: …Wait? I am not, I am not! Take your eyes off!
——For another example, after I came back from the world of [All Members Sexual Transformation], I met a new member of my brother’s band, his name is Akai, and I couldn’t help but hesitate: “You finally choose to change sex…?”
Whiskey Group: ? !
Akai: Huh?
——For example, in [Normal World], the hater Matsuda would play with fire on the Ferris wheel. Although he hates it, he must not understand common sense. But I remembered that my brother taught me a term called rebellious period. The more you stop him, the more he might do it. So in order to protect the other party’s fragile self-esteem, I decided to gently remind him.
“Songtian, I’ll find someone to help you figure it out, you’re not suitable for dating, you’d better be single for a lifetime.”
I think I’m awesome, because that way Matsuda won’t go on a date with the Ferris wheel in the Holy Land.
Matsuda: “??? No, wait, are you sure your brother isn’t playing with me? Zhufu!”
