I FOUND A DOOR TO TENSURA AND BECAME BROKEN IN THE REAL WORLD TOO-Chapter 27: Mastering Magic and Rebuilding the Future

Yuuya stood before the remnants of his grandfather's house—his Grand PA home. The once warm and welcoming cottage, which held so many memories, was now barely standing. The roof had partially caved in, and the wooden walls were worn with age. The paint was peeling, and the foundation was unstable. However, as he gazed upon it, there was no trace of the timid, insecure boy he once was.

Instead, his eyes were filled with calm determination. After weeks of training in the other world, mastering magic, and becoming stronger and more confident, he was ready to take on the next challenge: rebuilding his home.

Yuuya, now dressed in stylish yet practical clothing, walked confidently into the local construction office. His posture was firm, his stride measured. The staff who greeted him barely recognized the once awkward and shy boy.

As he approached the counter, a middle-aged man with a sturdy build and a clipboard in hand glanced up.

"Hey there, how can I help you?" the contractor asked, offering a professional smile.

Yuuya met his gaze with steady eyes. His voice, once hesitant, was now clear and self-assured.

"Hello. I'm looking to hire a team to rebuild my grandfather's house out near the forest. I want something modest but durable—a home that holds sentimental value but doesn't stand out too much."

The contractor raised a brow, slightly surprised by Yuuya's confidence, but nodded.

"Sure thing. Do you have any specific designs or modifications in mind?"

Yuuya handed over a neatly drawn blueprint—sketched with the help of magic-enhanced precision. The design was simple but practical:

Two stories, with a cozy living room, modern kitchen, and spacious bedrooms.

Reinforced foundation and walls for durability against the elements.

A basement with hidden compartments—perfect for storing artifacts and magical items he might bring back from the other world.

"Hmm... clean, efficient layout. Shouldn't be a problem," the contractor said, impressed by the level of detail.

He glanced at Yuuya. "You seem pretty young. You sure you can handle the cost?"

Yuuya smirked slightly, a far cry from the bashful smiles of his past self.

"Don't worry about the money. Just focus on doing a good job."

Without hesitation, he handed over a stack of bills—money he had discreetly earned by selling rare materials from the other world. The contractor's eyes widened slightly but nodded with approval.

"Alright, kid. You've got yourself a deal. We'll get started next week."

As they shook hands, Yuuya's grip was firm and steady—no longer the uncertain touch of a meek boy but the grasp of someone who knew his own strength.

After securing the contractor, Yuuya returned home and stood before the mysterious door that led to the other world. It was too risky to let outsiders discover it during the renovation.

Taking a deep breath, he raised his hand and channeled his magic power, which now flowed through his newly inherited magic circuit with absolute mastery. His eyes narrowed in concentration.

"Let's see if my illusion magic is as good as I practiced," he muttered confidently.

He visualized the wall perfectly—down to the grain and imperfections—and cast his spell. The air shimmered slightly as the illusion took hold, seamlessly blending the door with the surrounding wall. It appeared as nothing more than a solid, unremarkable surface.

He pressed his hand against the illusion—his fingers easily slipped through the hidden portal. However, to anyone else, it would feel like touching a regular wall.

He grinned, satisfied.

"Even if someone leans on it, they'll never know it's here. Perfect."

To ensure it was tamper-proof, he added an extra layer of magical reinforcement—invisible to the naked eye but powerful enough that even heavy machinery or explosives wouldn't breach it.

A few days later, eager to put his magic into real combat practice, Yuuya ventured deeper into the Jura Forest—far beyond the safe regions he once timidly explored. The forest was vast and untamed, and as he ventured into its heart, he felt his magic coursing through his veins with natural ease.

Suddenly, he caught sight of a humanoid lizard, unlike any he had read about in Tensura. This one was larger and more armored, its scales glimmering like obsidian steel, with a malicious glint in its yellow eyes.

The creature turned and let out a low, guttural hiss.

"Looks like you'll make for some good practice," Yuuya said confidently, his tone cool and unshaken.

The lizard lunged forward with shocking speed, but Yuuya's agility was leagues beyond what it once was. With a flicker of thought, he activated [Acceleration], his body becoming a blur. He sidestepped the attack with flawless precision.

"Too slow," he muttered.

He extended his hand, summoning two massive [Water Blades], slicing through the air with incredible speed. The blades slammed into the lizard's flank, sending it crashing into a tree, but the creature barely seemed fazed.

"Hmm, durable... let's crank it up."

He clenched his fist, his magic surging outward. The ground trembled as he conjured [Earth Spikes], which erupted in jagged formations around the lizard, pinning it in place.

The monster roared and spat corrosive acid at him, but Yuuya reacted instantly, casting [Barrier] with a single thought. The acid splashed harmlessly against the shimmering shield.

"Not bad. But I'm just getting started."

With a grin, he channeled flames into his palms, launching a wave of [Inferno Bolts] at the lizard. The fireballs blasted against its armored hide, searing through the scales. The lizard screeched in agony, but Yuuya wasn't done.

He dashed forward, his agility-enhanced movements making him nearly invisible. With a swift motion, he summoned a massive [Thunder Spear] and hurled it, striking the lizard square in the chest. The creature's body convulsed violently from the surge of electricity before it finally collapsed, lifeless.

Yuuya stared at the charred corpse, breathing steadily.

"Looks like my magic's coming along nicely."

After the battle, Yuuya opened his status window, eager to see how much he had leveled up.

[STATUS WINDOW]

✅ Name: Yuuya Tenjou

✅ Level: 1450 (previously 850)

✅ HP: 19,600 → 42,800

✅ MP: 35,200 → 78,600

✅ Attack: 28,900 → 62,300

✅ Defense: 30,000 → 70,000

✅ Agility: 32,000 → 74,000

✅ Intelligence: 26,500 → 65,500

✅ Luck: ∞ (EX)

He smirked in satisfaction, closing the status window with a flick of his hand. The sheer leap in his stats was staggering. His Attack, Defense, and Magic Power had skyrocketed, and his Agility now allowed him to move at near-impossible speeds, making him a blur to the naked eye. Even his Intelligence had dramatically increased, allowing him to process complex spells and tactics with newfound ease.

Yuuya took a deep breath, feeling the raw power surging through his body, and he couldn't help but chuckle softly.

"Wow..." he muttered to himself, his voice calm yet filled with awe. "Seems like mastering magic caused my levels to skyrocket."

He flexed his fingers, feeling the magic flowing through him with such familiarity now—it was almost second nature. He could manipulate mana currents as effortlessly as breathing, commanding the elements and shaping reality with his imagination alone.

But as he stared at his status window once more, something odd struck him. His brows furrowed slightly, and he tapped his chin thoughtfully.

"Wait a minute..." he murmured under his breath. "These stats... they're different from what I read in That Time I Got Reincarnated as a Slime."

In the book, the strongest beings—monsters, demon lords, and even True Dragons—were described in a completely different statistic format. Yet, his own power was measured in raw numbers, making it difficult to gauge how he compared. Even though his levels had skyrocketed, he was still unsure where he stood in this new world.

He stared at his Attack, Defense, and Magic Power, which were now well into the tens of thousands. By Tensura standards, this would have made him an A+ ranked monster, perhaps even on par with some weaker Demon Lords.

However, as he reflected on the monsters of legend from the book, he quickly realized he was still far behind.

"Yeah... my stats look amazing, but if I think about it..." he muttered, his eyes narrowing slightly, "the likes of Guy Crimson or Veldora probably have levels in the millions... maybe even beyond that."

He exhaled slowly, feeling the weight of reality settle on him. The power he had gained was staggering, but compared to the top-tier beings in the Cardinal World, he was still barely scratching the surface.

"Even if I've gotten this strong... I'm still a speck of dust compared to them," he mused, a slight grin tugging at his lips. There was no hint of discouragement in his voice—only determination.

After all, this only meant he had more room to grow.

He glanced down at his hand, summoning a small orb of fire magic. The flame flickered with intense heat, yet it felt almost weightless in his palm. With a casual flick of his wrist, he sent it soaring into a cluster of boulders nearby.

The moment the fireball made contact, BOOM—the explosion was far larger than he intended, sending a shockwave through the area. The ground shook violently, and the boulders were instantly reduced to rubble, with splintered trees and cracked earth marking the blast radius.

Yuuya's eyes widened slightly at the sheer destructive force.

"Whoa... that was supposed to be a basic fireball..." he muttered in mild disbelief.

But when he opened his status window again, he noticed that his MP barely dropped.

"Huh. Even after using that much magic... I've barely lost any MP?" he mused, narrowing his eyes in thought.

He clenched his fist, and the magic circuits within him flared to life. His magic power was so vast and efficient now that low-level spells barely made a dent in his reserves.

"Let's try something... bigger."

Without hesitation, he focused his magic into his palm, conjuring a swirling vortex of water and ice.

"[Abyssal Frost Lance]," he muttered with a smirk, giving the spell a name.

The spell's mana signature was unlike anything he had ever cast before. The lance was massive—twenty meters long, made of compressed ice and water magic, and swirling with frost-infused winds. The air around it shimmered with freezing mist, instantly lowering the surrounding temperature.

"Go."

He launched the lance at a massive stone outcrop in the distance. Upon impact, a towering pillar of ice erupted, freezing the entire area solid. The stone, once sturdy and ancient, shattered into glittering frost-dust from the sheer force. The icy mist spread outward, covering a radius of several hundred meters in frost.

Yuuya exhaled slowly, watching the frozen aftermath. His eyes narrowed in contemplation.

"That... was way too powerful for a mid-level spell," he muttered.

He opened his status window again and confirmed his suspicion—his magic multiplier had grown exponentially. Every spell he cast was now being amplified far beyond normal limits, making even simple spells devastating.

As he surveyed the frozen landscape, Yuuya's smirk widened. The realization of his limitless potential sank in, and with it came a new wave of confidence.

However, he remained grounded. No matter how powerful he became, he was aware that he was still nowhere near the peak.

"If Guy Crimson or Veldora have levels in the millions..." he murmured to himself, clenching his fists, "then I've still got a long way to go."

There was no frustration or disappointment in his voice—only resolve.

The once shy, timid boy who had stumbled into this world was gone. Now, he was a dominant force, someone who could shape the world with his own will and power.

His golden eyes gleamed with excitement.

"If I've already come this far... just how strong can I get?" he muttered, his voice filled with calm anticipation.

He turned toward the forest, his gaze unwavering.

"I guess there's only one way to find out."

With newfound resolve, he strode forward, eager to continue testing the limits of his ever-growing power.
