What could exist beneath the cold, damp, and dark underground?

Apparently I don't know... But who knows what will happen?

――――

Boom - [The sound of two extremely fast things breaking through the air]

A sword aura emitting a pale white light and a fireball emitting orange-red sparks flew towards the "Underground Guardians" located at the entrance in front of me, and I almost lost my feet and knelt on the ground covered with rubble in the next second.

Bang!boom - [sound of explosion]

Although the 'Underground Guardians' who were attacked by sword qi and fireballs said that they had obvious injuries on their bodies, it only took a few seconds for them to recover from the sword wounds on their bodies that were broken by the sword qi and the injuries caused by the fireballs.

(Isn't this regenerative ability too perverted?) If the "Underground Guardian's" recovery ability is compared to the unspeakable multi-hand, then it is clear that the former is heaven and the latter is earth.) ）

Just because of this, the series of battles I've fought with the Underground Guardians have been futile and useless... It's just in vain......

[Ho ho ho ho ~ Didn't I say that no matter how much you fight them, it's useless. You see, isn't it in vain that you?]

Half-kneeling on the ground, I frowned slightly as I listened to the hot sneer coming from behind me, and although I was unhappy with the owner who made the sound, it was really right.

"Tsk!"

Thinking of this, the unwilling thought in my heart seemed to dominate my thoughts, and after storing the "Lost Black Talisman" in my right hand into the scabbard that I was carrying behind my back, I removed the short crossbow that I was carrying behind my back.

[Is this going to be a short crossbow? do you think that kind of thing can really deal damage to the Underground Guardians?]

Holding the short crossbow with both hands, I didn't pay attention to the question raised by the mask behind me, but held the crossbow arm with my left hand, stepped on the pedals in front of the crossbow machine with my foot, grabbed the left hand of the crossbow arm and pulled it up, and the crossbow string was finished, my right hand was not idle, I took out a crossbow arrow from the quiver and loaded it into the ditch arrow on the front of the wooden arm, and after loading the crossbow arrow into the ditch arrow, I held the short crossbow and aimed at the "underground guardian" standing at the entrance, and pulled the trigger without hesitation.

Whoosh - [The sound of the sharp weapon being launched and breaking the air]

The moment I pulled the trigger, the bolts loaded in the grooved arrows were fired at breakneck speed, and the arrows that flew out of the way struck the head of one of the many Underground Guardians standing at the entrance, the sharp arrows effortlessly piercing into its eye sockets and through its brain, stuck in it.

Bloody blood flowed from the right eye socket of the 'Underground Guardian', and if it was expected, the 'Underground Guardian' who was shot by the crossbow arrow I fired should have let out a rather miserable scream at this time, but at this time it didn't want to let out any pain at all, but instead pulled out the crossbow arrow stuck in its skull with its left hand as if it was nothing. As the crossbow arrow was pulled out by it without hesitation, its originally injured right eye recovered at a speed that was impressive to the naked eye, and in just a few seconds, the right eye of the "Guardian of the Underground" was completely recovered, and it looked at the crossbow arrow in its hand, and after hanging part of the brain tissue arrow, it casually discarded the arrow to its feet.

“......”

（...... Didn't hurt at all? I thought I might be able to kill them if I hit them in the head... But I was obviously naïve...... ）

I couldn't help but put on a rather bitter expression when I thought about this, and I couldn't help but feel a sense of futility as I looked at the 'Underground Guardian' who had not done anything about the previous crossbow arrow in the head.

[So... Didn't I tell you, that short crossbow in your hand can't effectively fatally damage the Underground Guardians. ］

The mask behind me said indifferently as if it had read my thoughts, and I couldn't help but bow my head slightly when I heard what it said.

Ignoring the mask's words, I wound my crossbow again, took a crossbow from my quiver and filled it in the trench path, and then aimed it at the "Underground Guardians" standing at the entrance again, pulled the trigger, and the sharp crossbow shot at them with a swift sound, hitting their flesh and passing through it with ease.

[Still not giving up?]

The mask in the rear position asked again.

"I know what you're saying... But at the slightest possibility, I'm going to have to try!"

I responded to the mask's questioning like a weirdo, and rewound the crossbow in my hand and filled it with the bolts.

[I really can't help you...... ］

――――

I don't know how much time has passed, but I don't have any idea of how long time has elapsed since I stayed in the underground cavern of the ruins of "Lesa Yaga......

"Huh-"

I yawned, sat down next to a half-kneeling skeleton, counted how many arrows were left in my quiver, and after counting the few arrows left in the quiver, I put the short crossbow in my hand on my back.

(Are there ten left...... ）

After counting the remaining number of crossbow arrows, I sat on the ground, stretched my body, which had become stiff from exertion, and then lay on my back on the ground to rest.

[Hey, goblins.] Are you tired?]

At this moment, the mask seemed to be caring for me, who was lying on the ground resting.

"It's a little tired. I've run out of stamina and magic, and now I just have to rest. Listening to the greeting of the mask, lying on the ground, I slightly hooked the corners of my mouth and responded to the mask with a wry smile.

[That's really bad~ Anyway, let's get some rest first, goblin, and I have something to say to you when you wake up.] ］

Hearing what I said, the mask smiled at me and said to me with concern, and it told me that there was something important to say to me when I woke up again.

"That's right. You are...... What's the word... Do you want to say something to me?"

As soon as I finished saying this, a strong sleepiness instantly swept through my mind, and in the next second, my eyes fell weakly, and I fell asleep.

[Oh ~ look at it this way... He still looks quite fragrant when he sleeps~]

Not long after I fell asleep, the mask that floated in the air, glowing blood-red, muttered to itself in a slightly happy voice.
