The vault was hidden away at the lowest part of the island, so it wouldn't be visible when people did underground scans of the island.
Faced with the wall of metal that blocked his way forward, there was only one thing Ren could do.
Dig straight down!
Having come prepared for the occasion, unlike during the battle royale, Ren set down a couple of sticks of dynamite on the floor.
Then Ren made countless holes in the ground below, laying down sticks of dynamite in each of the holes.
"...that should be more than enough firepower, shouldn't it?"
Stepping back from the dynamite, Ren manifested a dagger before allowing it to shine a blood-red.
Falling father back into the tunnel, Ren made sure he was far out of the blast range before readying his blood-red shining dagger.
Raising the dagger above his shoulder, Ren acted like he was shooting a bow as he calculated the perfect trajectory for the dagger so that he hit the dynamite.
"You know...at this very moment, I think I might just be happy I got transmigrated into this world instead of having to go to college."
Going to lectures and taking midterms?
Hard pass!
Destroying shit with bunches of dynamite in a world filled with magic.
"HELL YEAH!"
Recalling those American movies where the main characters would set off explosions and then walk away, with the explosion visible in the distance as they walked away in slow-motion, Ren smiled.
A high-school student turned magic-school student turned actor!
Reeling back his hand, Ren released the dagger from his hands, allowing it to fly forward gracefully.
Spinning around in the air, the dagger began its descent, aiming right at the sticks of dynamite closest to the metal wall.
Turning around, partially to recreate the scene... and partially out of fear, Ren covered his ears before sprinting away.
At the same time, the dagger perfectly landed on the sticks of dynamite, the blood-red tip of the tag embedding itself in one of the sticks.
*BOOM*
*BOOM*
*BOOM*
*BOOM*
*BOOM*
In quick succession, the first stick of dynamite activated, causing all the ones around it to detonate and finally causing the sticks below the grind to explode.
The entire tunnel ground shook, throwing Ren off balance and forcing him to cling to the wall to balance.
Simaltenousy, above the ground, the explosion shook the ground where Kanzuki was sitting, instantly waking him up from his daydream.
Feeling the ground shake, Kazuki quickly stood up confusedly before glancing around.
"Principal Seraphina...?"
Hearing no response from the principal, Kazuki cautiously walked over to the tunnel before looking downwards.
Almost immediately, though, he covered his eyes and looked away upon seeing the mountain of corpses below.
Not completely dismissing the earthquake, Kazuki simply stood by the hole with his spear ready.
Right below Kazuki, Ren slowly uncovered his ears as the sound of rocks tumbling around and dynamite blowing up came to a pause.
Turning around, Ren covered his mouth with his hand upon seeing the damage.
"...I might have miscalculated... by a tiny bit."
Walking towards where the floor used to be, Ren saw a massive crater.
The crater completely separated Ren from the metal wall, which was somehow not dented or damaged in the slightest.
Well, that was to be expected.
In the end, no matter how loud or strong they were, dynamite were a regular-human good while the metal wall was embued with magic, a divine energy.
However, Ren could not care less about the undamaged metal wall.
Looking down at the crater, Ren didn't see any ground...there was just water.
At the very bottom of the crater, instead of the floor, the water below the island was visible.
Staring at the ocean-blue water at the bottom of the crater, Ren peered downwards, making sure the seafloor was deep enough.
And sure enough... Ren was looking at the ocean.
Picking up his last dynamite stick, Ren walked to the very edge of the hole.
Like a rose, Ren placed the dynamite stick in his mouth, holding it there with his teeth. Sёarᴄh the NovelFire.net* website on Google to access chapters of novels early and in the highest quality.
With a stick of dynamite now in his open mouth, Ren manifested yet another blood-red dagger.
Shedding his sweatshirt and shirt, Ren took one last glance at the cave... before assuming a diving posture?
Ren, with his two legs stretched out ahead of him, kneeled down on the ground while his head looked straight down into the water.
In a graceful motion, Ren used his two back feet to propel himself in the air.
Then, mid-air, Ren flipped, with his two hands facing the dark blue ocean water.
With his legs up to the ceiling of the cave, Ren rapidly descended deeper and deeper until his hands finally hit the ocean water.
Seamlessly, Ren passed through the water, diving all the down to the ocean floor.
Clenching his teeth, Ren also managed to keep the dynamite stick from slipping out of his mouth.
Flipping around once again, Ren stood on the ocean floor, staring up at the massive body of the land above him.
The ocean was pitch black as the island prevented the sun from reaching it; however, that was no problem for Ren with his enhanced eyesight, which was also enhanced by his perk, "Sea God's Believer."
Basking in the sensation of the water for a second, Ren quickly glanced around before raising his blood-red dagger.
Then, propelling himself off the ocean blue, Ren slowly ascended upwards until his dagger was touching the bottom of the island.
Pushing his dagger up further, Ren made a hole in the bottom of the island eventually.
Removing the dynamite stick from his mouth, Ren used his other hand to push the dynamite up, embedding it in the island.
The stick of dynamite was put in a hole in the island that Ren had made, so no water was touching it.

Then, flipping around in the water once again, Ren turned around so that his feet touched the island, and his face stared right down at the ocean floor.
