Every time I wake up, it seems I find myself in a new place, or even as a completely different person—a technologically advanced academy city…

The Mechanical Age of Human Extinction... Gensokyo, Favored by the Gods... The Everlasting Light of the Ultra Star... Another World of Demon Kings and Heroes...

I'm Nobita Nobi, a genius, and I don't have a Doraemon. Until one day, I found a mirror in my room, and a Doraemon jumped out and said to me, "Nobita, have you seen Nobita?"... PS: Contains Kamen Rider elements; please don't read if you dislike that.

When I first woke up, I thought this was an ordinary everyday world. Because in my memory, it was a very peaceful world. After searching my memory, I thought it was a mixed anime world. Because in my memory there were people like Yukinoshita Yukino, Sawamura Eriri and others. When I touched the transformation device on the bedside table, I thought this was a world invaded by monsters. I will transform into a lone hero to save the world. When a group of people who claimed to be the Human Rights Security Agency came to me, I felt a little confused. What kind of world is this? When I met the person who claimed to be the president, the confusion reached its peak. "That's right! The president is me, Theresa!" So, is it too late for me to go back now? Let's get back to the point. After saying so much, there is only one thing I want to express. "Sure enough, knights and youth romance stories don't go together." "Amazon."

Jiang Xiaofeng, inheriting Kiryu Sento's knowledge and intelligence, arrives in the world of Douluo Continent 3 carrying Pandora's Box due to the will of the author, Jing Dagon. Can he become the Kamen Rider Build he envisions? Humans and soul beasts have a fundamental conflict, fueled by a hatred that has lasted for tens of thousands of years. Can Jiang Xiaofeng reverse this situation? "I don't know if I can change anything, but I can't ignore it. I want to try, to change it." PS: I'm a complete newbie, so there might be many flaws. Please point them out if you have any questions. This book's setting does not follow Douluo Continent 4; I couldn't stand Douluo Continent 4, and the later settings are too contradictory, and... ridiculous. This is a Douluo Continent knight story; if you don't like that, please don't read.

(This is a novel with a brain storage area; it's not a high-level web novel and has writing flaws. It's an equipment manufacturing story set in a fictional world.) (The beginning might be a bit slow and difficult to understand, but the author will try to make it more exciting. Please continue reading, thank you!) (The protagonist has enemies and points of conflict in the early stages of the book.) (The protagonist's creation of knights follows the established plot, so progressing through the technology tree might be slower.) (The early stages are slightly depressing.)

On Earth, decades ago, humanity was invaded by strange beings, whose methods proved insufficient to deal with the ever-emerging monsters.

At a time of life and death, an existence called the Light of Legend appeared. The Light of Legend granted humanity the qualification to become the chosen ones. Those chosen would become legendary knights (only those with a heart full of justice and a desire to protect can be chosen) or knights.

Each nation managed to hold onto its remaining territory using the legendary knights they possessed, and the legendary knights and their armies formed a battle line to keep the monsters at bay...

Lu Chengze, a graduate student majoring in mechanical materials science, was transported to Earth by a game called Knight's Workshop. He wasn't chosen by the legendary light, but the Knight's Workshop, which could create knights, became his cheat code...

(Limited-time bounty now open, see details) The deceased Ren Wei has accepted a commission from the World Will. Due to an invasion by outsiders, he must protect the world of comics spawned by the World Will. The popular heroines have become the targets of the Lord Gods and the Reincarnators! To protect the beauty of the second dimension, he fights in unknown corners. As a reward, he receives the power of a knight from another world...

A programmer who was terminally ill for various reasons died and ended up in the year 0078 of the Gundam Universal Century.

Confined to classrooms, companies, and hospital wards during his lifetime, he wanted to use his knowledge of the Gundam world to travel around the world and explore the universe.

Of course, it would be even better if I could make a fortune along the way.

But this universal century seems different from the world he knew so well.

Is this 0079? Or GQuuuuuuX? Could it be the timeline of THE ORIGIN?

It can't be... that three timelines are mixed up together..., can it...?
