MTL - Into Unscientific - Chapter 29 I need your help

I was on my way home with my friend when suddenly, I spotted a catgirl cosplayer who made my heart skip a beat.But something felt off—I couldn’t recall seeing her in any anime, manga, or games I had ever come across. Confused, I asked my friend standing next to me.To my shock, his response sent chills down my spine:“Huh? What catgirl? What are you talking about?”Suddenly, a truck came barreling toward the girl. Without thinking, I rushed to save her. In the end, both of us were hit by the truck.Now, I find myself reincarnated in another world—in the body of the very catgirl I had seen.But... who is this girl?How is she related to the dungeons that keep popping up in this new world?

“Hey monster, you're not ready for this blow, but I don't give a shit!!” said Lian as he drew a circle inside another circle in his mind.Then, a few seconds later, a fireball as big as a house hit a monster just over 4 meters tall...It was a waste of resources, but it was damn fun!“BOOM!!!” he said as the fireball reached the monster, covering it entirely.The excitement on his face was palpable as his clothes and hair fluttered from the power generated by the impact.[Accuracy: 97%]“Tsk, it's really hard to achieve 100% accuracy when casting spells... that just means I have to do better!”Meanwhile, the monster and the entire area around him was destroyed. The crater was huge, flames burned the ground, and ash mixed with dust covered the air.---In a world full of Gates, Mages and Knights work together to defend humanity from extinctionLian, a boy from a small town, awakens a very... unique system.Casting spells by drawing strange shapes in his mind had become normal for him by now.Thanks to the system, he had become a Mage, a human capable of using mana to cast spells.Facing monsters from the Gates had become routine. Studying magic was a pastime. After all, he had the System, he didn't need to study classical magic. Or maybe not...

“Pretend to be my lover and join the social circle.”

Selena, the top star that had the entire world’s attention, was suddenly warped to Northern Duke’s land during an accident while filming. Kalcion, the Northern Duke that saved her from the infernal beasts, offers Selena a chance to go back home in return for collecting information in various social circles by pretending to be his lover. Selena quickly accepts Kalcion’s offer, but…

“Why in the world can’t you do this!?”
“Don’t you think that the answer to that should be obvious to you, the actress, not to me, the duke?”

There was a critical problem. The Northern Duke’s acting skills are horrible!

“…Let’s change the plan. I’ll seduce you instead.”

And thus the contractual relationship between the two started. Will Kalcion’s acting skill improve first, or will he start to have true feelings for Selena instead?

For as long as he could remember, life had always been cruel.A young man in his early twenties—his name now lost to the past—was dealt a life filled with misfortunes.A cold, empty apartment, a soul-crushing job, and, finally, a terminal diagnosis.With nothing left to live for, his only comfort had been escaping into the fictional world of Path of the Elemental Sage, a story of heroes, magic, and survival.But fate had other plans.When death finally came for him, he didn’t fade into nothingness.Instead, he awoke in the world he had only read about—a world of chaos and danger where death lurked around every corner.The air smelled of magic, the sky was filled with possibilities.{«[Status Window]»}[Name: Lyrium Blackwood][Age: 16][Rank: D-][Skills: None][Elements: None}At first, confusion filled his mind.Who was Lyrium Blackwood?Why was he here?And why did this body feel so different?But as his memories returned, so did the realization: this wasn’t some blessing or second chance.He wasn’t reincarnated as the protagonist.No destined savior.No cheat abilities.No grand fate.He was just another mob, a face in the crowd meant to exist and die without leaving a mark.But this young man—the one who had left his old name and life behind—wasn’t the kind of person to roll over and accept his fate.“This world is dangerous. The protagonist isn’t the only one fighting for survival here,”he muttered, his red eyes deep and sharp.Unlike the naïve characters in the story, he knew the stakes.He’d read the web novel.He’d seen the carnage, the betrayals, the disasters that wiped out entire cities.And if there was one thing he refused to be, it was a pawn in someone else’s game.“I don’t care about glory. I don’t care about saving the world. All I care about is surviving—no matter what it takes.”Lyrium Blackwood wasn’t planning to live quietly or avoid danger.The only way to survive in this brutal world was to rise to the top.To be strong enough to stand above both heroes and villains.Using his knowledge of the story’s events and his iron will, Lyrium sets out on a relentless path to surpass the protagonist.Whether through clever manipulation, brutal training, or sheer desperation, he’ll climb higher and higher, leaving nothing to chance.But the deeper he gets, the more he realizes that this isn’t just the story he once read.As fate pushes him closer to the heart of the narrative, Lyrium begins to suspect that his reincarnation wasn’t an accident—and the world itself might be watching him.“I don’t care who or what stands in my way. If the story wants to kill me, I’ll rewrite the ending myself.”----------------------------------I apologize for any mistakes in this story, as it’s my first attempt at writing a novel.
