Because of an accident, Tang Zijun traveled to a parallel world.

Traveling with him was an unknown Kamen Rider Belt.

After realizing that there was a strange inner world called the Mirror Plane hidden beneath this world, Tang Zijun spent several years alone to successfully eliminate all the monsters in the Mirror Plane.

At the same time, he is gradually adapting to his new identity.

Just when he was living the peaceful life he wished for, Tang Zijun accidentally discovered his sister's secret - she was actually a magical girl!

Could it be that there is a faction in this world that even he doesn't know about?

Are there more evil monsters than just one in the Mirror Plane?

Was I going to have to watch my sister live the same dangerous life I had before?

Regarding this...

Being transported to Beika Town, a city with a crime rate far exceeding Gotham's, is a rather unfortunate situation. But who says Beika Town is necessarily hell? Here, thirty years equals three months, granting you immortality. Here, the Suzuki Group is an absolute beacon of financial investment. More importantly… criminals here won't recant their confessions unless their lawyer is Eri Kisaki. Criminals here will accept circumstantial evidence unless their lawyer is Eri Kisaki. Criminals here are flamboyant and masters of intrigue, scattering clues everywhere while claiming to commit the perfect crime. Prosecutors here, even if the police arrest the wrong person and lose the trial, will only blame their own incompetence. Police here have substitutes for their jobs, guaranteed marriages, and even fatal injuries are protected by the Grim Reaper, so there's no worry about their downfall. "Putting aside the drawback of being stuck in the timeline and unable to climb the ranks, this is heaven." The Metropolitan Police Department's Investigative Division…

When Kawahara Momoka and Isen Rina picked him up from that rainy night,

What is he looking for again?

Looking for your former home?

Looking for the most important person in your life?

Looking for the meaning of your existence?

Looking for your empty, non-existent heart?

“What is the meaning of my existence?”

The black-haired boy questioned himself

The voices around him seemed to say to him:

You have no meaning in existence...

Several voices appeared to refute

"Brother Lin... is the most important!"

The red-haired girl called out

"I want to be...your God!"

The gray-haired girl who is no longer autistic declares this

"Give me the middle finger!"

But this time, they hooked their fate with their little fingers.

"Moving forward in confusion!"

They used their fists to disperse the darkness before them.

(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...

This is an adventure guild that transcends dimensions. People from different worlds post and accept commissions here. However, ever since Suou joined the guild, the normal mission commission board has begun to change. And it has gradually been flooded with messages from some people: Shokuhou Misaki posts a specific commission: @Shoufang. Shopping for bags, come quickly. Hayasaka Ai posts a specific commission: @Shoufang. The latest noise-canceling headphones are on the market, let's go buy them together. Tokisaki Kurumi posts a specific commission: @Shoufang. Many clones have been a little restless recently, please come over and help me calm them down. Suou Fang: "..." What on earth do you guys think of the sacred adventure guild? Suou Fang wanted to say that. Until he took a look at the rewards for the mission commissions... but they gave too much!
