"What kind of system should I create for myself?" murmured a young man named Ren Kamijou, a slightly-above-average-looking youth with long wavy hair and glasses.
(A/N: Just imagine the MC's appearance similar to Ren Amamiya from Persona 5)
The young man, who looked like a typical high school student, was deep in thought. He was currently facing a dilemma, having to decide which cheat or system to create with the cheat ability he had gained after transmigrating to another world.
Yes! Transmigration! Ren had been isekai'd without any clear reason after fainting from falling into a hole that suddenly appeared on his way home from school.
Somehow, he found himself waking up in a fantasy world filled with magic after witnessing someone use magic right before his eyes.
The sight left him completely shocked, but also filled with excitement after realizing that magic and fantasy truly existed in this world.
At first, he begged the mage to teach him any kind of magic—even the most basic one—but reality poured cold water on him as he discovered that not everyone possessed talent for magic. And as a person from another world, his body and structure were completely incompatible with this world's people, making him entirely untalented in magic.
Just as he was about to fall into despair and depression over his future in this world, he suddenly realized his cheat power, which allowed him to create cheats or systems for himself—or even for others!
However, since his cheat only allowed him to create a cheat for someone (including himself) once every 100 years, he was extremely careful about deciding which cheat to make so he wouldn't regret his choice.
"Should I make a chat group system? That way, I could travel between worlds and strengthen myself by gathering all kinds of powers from other worlds too," he muttered, rubbing his chin seriously. Unfortunately, after some consideration, that idea didn't quite feel right to him.
"I could also create and give the group chat system to someone else, and later invite myself into that group. So, that idea still isn't perfect!" As the cheat or system creator, he had full control over any cheat or system he made, including any power or benefit the system's owner gained, which would also be fully shared with him.
Ren fell into deep thought, recalling every OP and powerful cheat or system from the many novels and fanfics he had read. One by one, he considered each system, only to reject them because he wasn't fully satisfied.
Time passed, until finally, after several hours, he recalled a certain fanfic he had read—a fanfic with a system that was absolutely outrageous and overpowered, its functions sounding ridiculous even when he first read it.
"Let's make that one! Hopefully, I can recreate it!" With an excited and expectant face, he immediately activated his cheat and input all the detailed information for the system he wanted to create.
"It worked! I can't believe my cheat was able to create such a powerful system! Hahahaha! With this, I'll become the strongest being in the entire Omniverse! Or even beyond it!" He laughed loudly, completely ignoring the strange looks he was getting from the people around him in the tavern.
"Hey boss, do you think he's insane?" one man whispered to the person next to him, glancing curiously at Ren.
"Maybe? But he seems really happy about something? Anyway, just ignore him if you don't want trouble later," the man called "boss" replied, flicking his subordinate on the head.
Back to Ren, his eyes were now burning red as he stared at the sci-fi panel interface only he could see, where he found many function options provided by the system he had created:
[ID/Name = Ren Kamijou
World Traverser (Edit) = Frieren: Beyond Journey's End
Task & Reward (Edit)
Mall (Edit)
Temporary World (Edit)]
The system looked simple and ordinary at first glance, but the (Edit) option on every feature was what made it so outrageously overpowered and absurd!
"This system is amazing! I have no regrets reading the fanfic 'I Am The System!' by Yuuya3 on Webnovel. Who would've thought one day I'd be able to replicate the system from that fanfic?" Ren mumbled, his face showing complicated emotions—life sure was full of surprises.
So, why did Ren consider this system the strongest and most outrageous? Simple! As he had explained, thanks to the (Edit) option on every feature, he could fully control and edit anything in the system however he pleased.
For example, if he wanted to buy a skill in the Mall feature that normally cost tons of SP (System Points), with the (Edit) option, he could freely adjust all item prices to be extremely cheap—or even completely free!
And in the Task & Reward feature, he could create his own tasks and even decide what rewards he would receive upon completing them!
That's why this system was incredibly OP—perhaps the strongest system he had ever known across fiction or fanfics!
(A/N: This is my personal opinion—after years of reading fanfics, only the system from the fanfic 'I Am The System!' has the most OP system I've seen, plus its cosmology scale is completely insane. If I'm not wrong, the MC in that fanfic has surpassed omniversal entities.)
So, without hesitation, Ren immediately edited the shop feature to make everything sold there completely free!
[Edit:
Cost = 1–∞ → 0
YES/NO?]
Without a second thought, he clicked YES, and like magic, everything in the mall became free with zero cost!
"Hahahaha!!! This is fucking awesome!!!" he laughed loudly once more, making everyone around him even more convinced that Ren was completely insane.
