MTL - I Have a Big Problem with My Achievement System - ~ Update instructions~

The only game in my life that makes me laugh: The Lands of The Lunerra... I played this game for six thousand hours in three years, and the day I thought I had done everything I could in this game, I felt a great emptiness inside me. I thought nothing in my ordinary and monotonous life could make me happier than when I played this game. But it didn't take long for me to realize that I was wrong with an e-mail I received the night I finished the game.

Hi! Thank you to everyone who came to read this story. There are two things I want to tell you.

First of all, I first started writing this about two years ago, but I was writing in my native language, Turkish, and on a different site. But unfortunately, the website where I published the series came to the brink of collapse. While I was thinking about where to publish the series, I remembered Webnovel and here I am. So this is my first English novel and I believe I will make mistakes while translating. Please forgive me for these if you encounter some of them. I will do my best.

Second... yes, while writing this novel I was inspired by most of the novels I've read so far. Like The Novel's Extra, that novel is a pure diamond for me and I don't think I will ever reach the level of that thing. So I want to say the first few chapters may feel familiar to you, but I'll do my best to smooth it out.

Dear readers! Without any ads, maybe you will prefer .

Roy’s life was nothing special. The only thing commendable was the last few moments when he saved a mother and her child from a drunk driver.
…
It’s really an egg! Damn it, what kind of monster have I become? Did I fall into Hell instead of making it to Heaven??
Join Roy as he ventures through various worlds with the Custom Made Demon King System—a system that allows Roy to draw anything he can imagine and create it through exchanging souls!

The story is about a man who’s opposed to the now-common practice of implanting false memories, but is one day given memories of a fictional childhood friend. This fabricated happiness torments him, but then, to his surprise, he meets her – a girl who shouldn’t exist.

A girl who calls herself a demon appeared before a timid student named Fumio Kijima. The girl claims to be a campaign girl from the demon world and she gives him the ability to “summon a room” from nothing but thin air.

At first he doesn’t abuse his power and uses it as a convenient ability in his every day life. But one day he is bullied by his classmates under a false pretext and is made to suffer. In the past he would have wallowed in misery and cried himself to sleep, but now he had a power to call upon.

“I will make them regret it!”

Using his powers to summon his “room”, he begins his era of confinement and brainwashing to achieve his goals.
