I was able to get my level up again by wiping out the dark boa.
　...... Actually, the Guardian Golem defeated me, but its experience seems to be going into me as its "owner".

'My level has reached 45. The sub-skill [Enemy Radar and Convergence] within [Otherworldly Person] is now released.

　They've released another new sub-skill.
　Currently, I'm level 45.
Enemy Radar] searches for the location of demons within a 450 meter radius with me at the center.
Activating 【Energy Radar Convergence】 limits the search area to the front, but extends the search distance by 4 times.
　In other words, it is possible to search for the existence of monsters up to 1.8 kilometers away.

'This is very useful.'

　The original plan was to activate the [Divine Speed Blessing S] granted to his suit and run around in the mountains, using [Spatial Leap] and [Enemy Radar] to get an overall picture of the herd, and then blow the center of the herd away with the [Super Large Magic Laser Cannon (Prototype)].

　But using [Enemy Radar and Convergence], it would save us a lot of trouble at first.

Let's do .......

　I activated it as soon as possible.
　From where I'm standing, I was able to include almost the entire area of the mountain in the search area.
The information on the location of the demon is displayed as a red dot on the map of the area in my brain using 【Auto Mapping】.

'It's bright red.'

　Everything from around the mountainside to the other side of the mountain was painted over by light spots that indicated demons.
　It was like the Night of the Hundred Demons.
　Well, there's a theory that the Hyakki Yagyo in Japan are like 'a group of demons fleeing from an incredibly strong demon'.
　Could it be that these demons are trying to flee from more terrifying monsters?
　...... For example, a black dragon.

　It's a possibility that I don't like to think about, but a bad premonition can be a good thing.
　I've been almost certain that the black dragon would appear.
　Well, it's better to think of the worst from the start so that when the time comes, you won't despair.

Anyway, let's start with the problem at hand.

　The swarm of demons is heading this way in a straight line.
　In other words, this is where the 'Super Large Magic Laser Cannon (prototype type)' comes into play.

　When I took it out of the item box, it had the size and shape of a tank.
　A turret of a size similar to the main gun of a battleship extends from the front of the angular turret with caterpillar.
　Behind it was an LCD-like screen, emitting a pale blue light.

　I gently touch the screen with my right hand.
　Then a low, inorganic voice drifted into my brain.
　This must be a function of the laser cannon.
　Compared to what I hear when I level up, the voice quality is a bit harder and more artificial.

'Activation sequence complete. May I begin the magic power filling sequence?''
I don't mind.

　As I replied, the screen flashed strongly.
　I felt as if something was being taken from inside my body stealthily.
　When I checked my status, I saw that my MP had been steadily decreasing.
　As I recall, the required MP was 10000.

'The magic power filling sequence is over. May I start the firing sequence?''

　I reply, "No problem," and the laser cannon begins to make a driving sound like something spinning with a ving ving.

'Ten, nine, eight, seven--'

　It was possible to operate the turret with just a reminder.
　I took a precise aim while comparing it to the information I got from the [Enemy Radar and Convergence].

"Three, two, one, zero.

　An extreme heat ray was released.
　It burned the demons out of every tree in the mountain.
　On the map in my brain, the points of light indicating the demons had disappeared.

　The laser radiation was still continuing.
　I pointed the turret slightly diagonally upwards and burned down the mountainside to the top.

　There was no more 10% of the demons left.

　The power of the laser cannon was tremendous, the trees on the mountain were erased, and moreover, the top of the mountain had been scraped away.
　The setting sun can be seen beyond the shaved summit.

　...... Huh?

　I couldn't help but doubt my own eyes.
　Suddenly the sky became distorted and a huge black sphere appeared, blocking the setting sun.
　It was like a scene of an eclipse.

　I immediately activated 【Appraisal】.

''The Black Dragon of Extremis.
　The dragon of disaster that only appears once every thousand years.
　The last time it appeared, it was hit by a powerful enemy and its scales have been given the 《Magic Reflex S+》.

　They're here.
　I'm here after all.

　The swarm of demons must have been trying to get away from this guy.
　The monster that is feared by the same demons ...... is the black dragon of extreme destruction.

　Moreover, it looks worse than the simulation we fought in the ruins.
《Magic Reflex S+》 doesn't that mean that the magic laser cannon isn't effective, but rather bounces back?
　Oh my God, this is a formidable foe.

　The black sphere cracks and cracks as it expands and expands.
　That's probably what the egg looks like.

　Eventually the egg burst from inside to reveal a ...... huge black dragon.

''Gaaaaaaaaaaaaaaaaaaaaa!

　A roar shook the earth.
　The point of light indicating the black dragon is at a point that just barely fits into the [Enemy Radar Convergence].
　Despite the distance of kilometres away, the intimidating feeling can be felt so far.

　The black dragon flaps its wings and slowly approaches towards us.
　I check my status.
Thanks to 【Magic Power Recovery EX】, my magic power had long since been fully recovered.
　I put the magic laser cannon away in the item box for now.
　Right now, it's not really of any use.

　The first attack came from the black dragon.

''Guuuuuuaaahhhh!

　A fireball was released from its mouth.
　It was only one in the simulation, but here it was two in a row.

　I immediately took out Hikino's table, grabbed its legs and swung it around.

''Ooohhhhhh!''　

　The first fireball was shot back.
　The reflected fireball slammed into the second fireball with furious speed, causing a huge explosion.

　The black dragon spat out two more fireballs.
　...... but that wasn't aimed at me.

　The fireballs were trying to head towards the city of Onen, far behind me.

　If the fireball hit the city, it would be a catastrophe.
　Miria-san, Iris, Krom, Relic, Guise, his wife and daughter, and the two girls I saved with the heel potion would all be burned to death.

　The black dragon's, red eyes were looking at me.
　It was a gaze as if it was mocking me.

　-- How does it feel to not be able to protect what you should be protecting?

　The black dragon narrowed his eyes as if to say so.
　''It's a lick.
　I completely understand the performance of the items I own through [Dexterity's Mastery].
　So even now, I'm not upset at all.

　...... I command the Guardian Golem that is waiting behind me.

'Barrier deployment, pinpoint and prevent it.'

　The Guardian Golem let out a driving sound instead of a reply, and raised its hands high in the air.
　A wall of blue-white magic power unfolded in the sky.
　Then a fireball collided with it.
　An explosion occurs.
　But the barrier is not a scratch.

　The fireball that was supposed to annihilate the city of Onen was completely blocked by the barrier.

''Guuuuuuaa!

　The black dragon roared.
　But its tone of voice seemed somewhat unsettled.

　I continue to order the Guardian Golem.

'Strike the black dragon. Support me.''

He activated the 《God Speed Blessing S》 and ran.
　I kicked the earth and leapt.
　As if to match that timing, the Guardian Golem deploys a barrier.
　However, that's not to prevent an attack.
　It's a foothold.

　I kick the barrier in the air and fly even higher.
　The barrier is again at the end of my flight.
　I stomp on it, higher and higher.

　In less than a few seconds, I was fleshed out by the black dragon.
　I take out my hikino wooden sword and slash at it as we pass each other.

　Apparently the scales are also sturdier, or maybe they weren't going to be cut in half.
　But with each slash, the damage is sure to come through.

　I kicked the barrier and slashed at the black dragon from all directions.

''Guuuuahhhh!

　The black dragon wasn't used to close combat, or perhaps it was only able to flail its limbs and tail in a mess.
　But there was no way such an attack could hit him.

''Haaaaaaah!''

　He swings the wooden sword and strikes!
　A response that cuts off the flesh.

　The black dragon's tail is slashed and it falls to the ground.
　As a result, the black dragon began to fall, as if it had lost its balance in the air.
　The black dragon collided with the ground as it was and became limp and motionless.

　''Did you do it?

　No way.
　If I defeated it, the body should be collected in the item box.

　I landed on the ground and went around to the front of the black dragon.

''Gu......a......!

　The black dragon didn't seem to have lost its fighting spirit yet.
　It stared at us while bleeding from its entire body.
　Black smoke was rising from its mouth.
　It was probably planning to shoot a fireball.

　But before that, I'm going to toss it in the air.

　I took out the 'Super Large Magic Laser Gun (Prototype Type)' from the item box.
　However, that turret is in the shape of being twisted into the mouth of the black dragon.

　The black dragon has scales of magic reflection.
　On the flip side, the inside of its body is defenseless.

　It was filled with magic power.
　The countdown begins and ends .......
　Before the black dragon could release the fireball, a zero-range magic laser burned its body.


　Check the item box.
'The corpse of the Black Dragon of Extreme Annihilation x 1' was stored in it.
