One hostage died and is no longer part of the objective. I didn't expect the killing of the hostages would occur ahead of time. Even though there is still time left behind to rescue them, it seems the timer was never meant to be a "timer before they will be executed", instead, it turned out to be a "timer of them being executed." If I dawdle any longer, everyone would die before I can kill everyone there.

"Damn it!"

I may be rushing here and there around the buildings but I am making sure I am still under stealth and still focusing on my surroundings. I don't want to get discovered by anyone and fail this quest after all the work of disposing of the elves.

"Master, I detect a demonic presence similar to mine when I am still a boss in a dungeon just northwest of our position. Not only that, I am sensing a few untainted individuals too," Atlas said.

"You can detect demon presences, Atlas?" I was surprised since he didn't have a skill that can detect demonic presences.

"Yes, Master. I just realized it when you were creating traps to prepare for the destruction of the demon hearts. I didn't expect that I can easily tell apart the demonic and non-demonic beings. I thought it was just some sort of fluke that I can detect them at first but now I am quite certain I can detect them."

"Then that is good! Now lead the way in which place you detected it!"

"Got it, Master!"

Due to the detection ability that Atlas has, I managed to find the place where the elves were being tortured and killed. The number 19 is starting to shake too when I just arrived. However, I can't just rush in. After all, I needed to keep my job as a person in charge of the sabotage to remain anonymous to all the enemies.

The place where the captured elves were taken was currently in a small building made of bricks. Out of all the houses here, this is the only place with a house made of bricks. I don't see any openings either which means this was meant to store something not alive. This place was meant for killing them all until they were going to submit to the demons.

Checking the door, it was locked and seems to need a special key. However, I don't have any key to open it.

"Damn, it's locked."

"What are we going to do Master? I can go and search the surrounding houses for a key," Atlas proposed.

"No need."

"Huh?"

"What's the point of a saboteur class if a simple lock stops their progress? Honestly, that is a pretty absurd thing," I grinned and create a blueprint.

A noiseless bomb. It is not destructive enough to kill people but it can destroy doors whatever it was made and whether it needs a special lock or not.

After creating the blueprint, I throw the blueprint into the ground and the bomb materialized.

"Even though the saboteur class can be considered as support, I can't deny that creating bombs like this makes me feel like going full explosion run."

Inspecting the door for a bit and analyzed how it will open, took a bit of time before I attach it to the door.

"Are you sure this will work, Master? It seems ineffective to me," Atlas comments.

"Don't worry. You haven't seen anything yet!"

Once the bomb was attached, I went to the side and press the trigger. The explosion occurred but as expected, it didn't create a sound. It just released a bit of smoke, opening the door successfully.

"Nice!" I grinned before checking the main entrance for any possible traps once the door is opened, Thankfully, it seems those things are not available.

There were some parts that looks suspicious at first but then I realized that they were illusions and the gem already filtered them out automatically, erasing the illusion.

"You said earlier that there is one demon among the untainted ones right?"

"Yes, Master. To be precise, one dead, 19 living beings untainted and a demon tainted one."

"So there is an impostor among us?"

"We don't really know."

"Let's get them before they have another dead person with them."

The building is big but it is empty. However, due to the illusions being filtered automatically in my eyes, the illusion to cover the basement was rendered useless.

Entering the basement reveals a very putrid smell of rotten smell.

"What a wonderful smell we have in."

"Are you being sarcastic there, Master? Even I can smell that rotten smell. That is not even considered wonderful."

Slowly descending the basement, it revealed a lot of dead bodies. Upon closer inspection, it seems to be the bodies of both demons and some elves. Most of them are already rotten that they are the cause of the very bad smell.

"Can you pinpoint in which area they were in? The basement is pretty expanse and dark. I don't have the luxury and time to search for them all."

"There, go straight from here then turn left. The life force of them is visible to me."

I nodded and went to the location that Atlas instructed. Pulling out the Versatile Weapon, I am ready to assault whoever is causing this amount of bodies scattered all around.

Arrival at the area, I saw some wounded elves and a few elves fighting a very big demon with multiple teeth showing. Some of the elves are trying to stall the monster but any second now and the monster will break free from being stalled.

I changed my weapon into a dagger and immediately leap into action. The moment the demon raised its body to break free from the elves, I took the chance and stab the soft part of his underbelly and slice it down until the very end of the demon's body. Due to how deep I did the slice, the guts and blood of the demon were released from the torn belly. The other elves also took action and started thrashing the guts of the demon. It took them a few seconds before they found the heart and rip it off from the guts.

"SKRRREEEEEEEE!!"

The demon released a shrill cry before it breathed its last. Its stiff body lost its life after.

Due to the demon's death, the elves fighting against it finally dropped their weapons and fall to the ground, huffing and puffing from the attack.

"The demon is finally dead!" the elves started screaming as they celebrated.

Due to the noise, they are making, I stopped their celebration.

"I am sorry to say but the celebration is going to be short-lived for a while. I know you guys are having a hard time against the demons but it isn't time to celebrate just yet. You guys needed to get out of here first."

The elves stopped their celebration and faces me, holding their weapons tight.

"You are the one who killed the demon earlier, but I have only seen you today. Who are you?! Are you an accomplice to the demons?" one of the elves asked.

"He smells like a human! But he also has the scent of wolves too."

"Please put down your weapons, I mean no harm. I came here to rescue everyone as a request from a kid named Gust and the first elder of the elf folk village."

One man perks up his ears when he heard Gust's name. "Gust? You have seen my daughter?! How is she? Is she safe and sound?" he frantically asked.

"Are you Sir Wind perhaps?"

"Yes, my name is Wind. How did you know?"

"Your daughter handed this necklace to me to relay it to you. She said you know what to do with it," I said before handing out the necklace that Gust has given for Wind to receive."

"This is indeed Gust's necklace! So you are here to rescue us!"

"Yes. I was here to destroy the demon hearts and kill the new leader leading this place but your daughter requested me to also rescue you since you were also captured by the enemy.

The elves were stunned when they heard what I came here for.

"The current elder is too strong and he is impossible to kill! You cannot defeat the guy!" one of the elves said.

"If it is moving, it can be killed. There is no such thing as an immortal bastard. Now, let's stop dawdling, we need to get out of here as soon as possible since this place will get more chaotic once I started facing the main enemy."

"Then, let's get out as soon as possible," Wind said.

"Wait. There is one thing I am tasked to do in here too and I needed to finish it," I said.

"Huh? What is it? Is there still anything left?"

"Yes," before stabbing wind in the head with my sword, cleaving his head in half. The elves then stopped the moment I did it. The sword didn't let Wind survive and immediately died.
