Maou-sama no Machizukuri! ~Saikyou no Danjon wa Kindai Toshi~ - Volume 6 Chapter 8

Mu Zhiyan, after being transmigrated a millennium (1000 yrs) into the future, discovered that he was raised by his adoptive parents as a tool for them to access the heritage his (dead) biological parents left behind. When he was at a loss for what to do next, he discovered that his body hosted an additional
pharmaceutical system.

For a chance to return to his era of Earth, Mu Zhiyan decided to practice and practice; he must train the system to full level as soon as possible.

However, reality gave him a slap in the face. The world is dangerous and dreadful, making Mu Zhiyan recall his mother’s words of holding a thick thigh, resulting in him locking his eyes on a cool general…

So the rumored mysterious Mu Master faced General Han with a serious face: “I allow you to follow me, General Han.”

General Han: “…”

She is the Crown Prince’s fiancee, but on the night of their wedding, an edict was made and she was given off to marry the crippled and paralyzed God of War.

At the end of the story, I found myself in the body of a hidden villain, betraying the heroines. Since I’m not particularly concerned about the end of the world, I’m calmly waiting for the finale… “You’re the only one who truly appreciated my painting of the boa.” “When I make plans to meet you at four, my heart starts racing at three... is this what they call being tamed?” For some reason, the heroines are starting to take an interest in me.

Zaiden Archman. He’s the main character in my novel called ‘Awakener’s Dead Harem’.

As an author, I love it when my main character suffers and is depressed.

He’s the main character that I took pride in. With my novel about to end, I pushed myself to write the last volume.

However, what I never expected was that it would be the end of me too. When I opened my eyes again, I had become Vincent Dihart, an Extra in my novel, who is only mentioned a few times in the novel.

I then found out a sad truth about my Main Character that I took pride in. He has changed.

He’s not the Main Character that I made. He’s a Reincarnator. Someone has replaced my Main Character. And that someone has read my novel.

I feel empty and betrayed.

As an Extra, I will not be able to save this world from danger.

Only the Main Character is the one who can save this world. But, he will also not be able to do it without being depressed.

So the answer is clear.

“I will make him suffer.”

This is my story about living as an Extra. And once in a while, messing with the Reincarnator to make him suffer.
