Versatile: Alternate World

All supplies check. Fully loaded gun, check. Alright, time to face the boss and deal with him.

I grab the nearby torch on the wall and approached the dungeon boss room. To open the boss room, lighting up the door with flames is the way for it to open. I traced the door for a bit, wiping off the small dust around it before I tap it with the torch. The torch's fire scatters around the surface of the door, igniting it in the process.

Since it already got caught in flames, I stepped back for a bit to avoid getting caught in the fire. I waited for a bit for the fire to spread since it needed to spread around the door before it will fully open up.

CLACK CLACK CLACK

The mechanisms of the door started to do their work and in a few seconds, the door was split open before falling down to the ground with a loud THUD.

I waited a bit before entering the door. There is a chance that the boss inside will fire a spell to the doorway before anyone will enter. It was a precautionary tactic we do in the past timeline if we wanted to fight the boss here. Failing to do so will, of course, kill you in the process due to the fireball being fired capable of inflicting instant death.

Just like I expected, a huge fireball was tossed out of the entrance. It exploded in the nearby wall after hitting no one. Now that the fireball is gone, time to go in and charge forward.

"Who dares to trespass my tomb?!"

Of course, the boss has finally appeared. A towering giant, rotten mummy. However, due to his high authority and high class, while he was still alive, he is not just an ordinary mummy.

[Pharaoh of Darkness] (3 phases)

Level 105

HP: 4,000,000/4,000,000 

Traits: Undead, Humanoid, Dark

The Pharaoh of Darkness is just an annoying bastard. Not only does he have 3 phases but he also has a lot of AOE skills and an annoying summoning skill. If not for the fact that I know how to handle him, I might be having trouble with him.

The moment he stood up from his throne, I started running from the opposite way and started to go to the torches installed in the walls. The pharaoh of darkness throws a few dark balls towards me but I quickly dodge them like nothing. Jumping over them is normal for me.

"Gotcha!"

The first torch was received. After getting the item out of the wall, I started running again but this time, I went straight to the boss.

"DIE, INTRUDER!"

I quickly traversed my way out of his attacks and dodge them without letting any attacks hit me. 

"Hup!"

When I was already next to the boss, I slide underneath him and immediately make use of his blindspot to head straight to his throne. Once I was standing on the throne, I throw away the torch to the throne and let the fuel on the torch spill, allowing the fire to spread.

"What are you doing?!"

I didn't respond and once again went to the farthest torch again and started to run towards it.

"AS IF I WILL LET YOU DO WHAT YOU WANT!"

He started to bombard environmental attacks, alongside some dark hand shadows that appeared on the ground that attempts to take hold of me while I am traversing towards the next torch.

"MY SERVANTS! BRING ME THE HEAD OF THE INTRUDER!"

Small magic circles appeared on the ground and mummies that are normal mobs from earlier started to appear from them.

[Summoned Mummies]

Level 50

HP: 10,000/10,000

Trait: Humanoid, Undead

Damn, he already started summoning small mobs. This will start to get messy soon. I pulled out the fodder magic sword and started to slice through the mummies he started to summon. They are easy to kill since they only have 10k HP but they are troublesome and annoying as they will multiply every kill and if they are not killed, they will increase more, and you will be forced to minimize their size or kill a few of them to make way. In any case, there is no way to reduce their numbers. You will just thin them out in a few seconds and they will increase in a few seconds too.

I grab the second torch and the little f*ckers started to grab on my foot. With a small yank, I release a strong kick allowing me to use the face of the mummy as a foothold for me to jump a bit higher. Landing on the wall, I put all of my force on my legs before I exerted all of my stored energy towards my next jump.

"HUP!"

BANG!

The wall I was using as my next foothold did not last and caved in but it allowed me to dash forward with force and allow myself to propel straight to the boss. The boss tried to catch me midair but I just quickly used his hands as my platform and jump towards his head.

"JUST WHAT DO YOU THINK YOU ARE DOING?"

"Stop asking and stay still you f*cking bast*rd!"

When I saw a clear picture of his left eye, I proceed to shove the torch to his left eye.

"GAAAAAAHHHHHHHHHH!"

He started to scream and before he can slam his rotten hands at me, I already went away and went straight to the nearest pillar and stood on the top. The Pharaoh started to scrape his face in hopes the torch I stabbed on his left eye will be removed. He then tried to sit down back to his throne to try and take out the torch but then, flames engulfed his butt, increasing the pain and burns he received. Not only small burns but some parts of the white cloth that has been strapped on his body have started to burn too.

"GAAAAAAAAHHHHHHHHH! IT BURNS! GAAAAAAAHHHHHHH IT'S BURNING ME!"

Now that he is now no longer focusing on me, time to do the job I originally came here for.

I point the muzzle of the gun to the struggling pharaoh. With the boss in my sights, it's time to see how this works.

"[Rapid Gunfire]!

A magic circle appeared on the gun's muzzle and instead of one bullet, all of the 13 bullets inside the gun were released. And it all hit squarely to the boss.

"GRAAAAAAAHHHHHHH!"

The squirming dead mummies have been reduced to ashes before disappearing and the boss fell down on the ground with a groan and still burning butt. After the gun released all of the bullets out of the gun, I quickly reload the bullets again, allowing me to have another round of bullets to use if I needed it again.

Checking on the HP, the boss has been reduced to the 2nd phase which means the single mag of bullets was capable of chipping a 4,000,000 HP boss. From the looks of it, it inflicts a lot of Critical damage allowing me to chip off more HP than it should have been.

"YOU BASTARD! YOU WILL..."

Before he can fully stand up, I aimed and pulled the trigger again. Since the cooldown of the [Rapid Gunfire] has a very short cooldown, I didn't save it up and activated it again.

"[Rapid Gunfire]!"

The gun released another torrent of bullets towards the boss and before the boss can even finish his monologue to begin the second phase, he was forced to go down as he was sent to the final phase of the battle.

After he was reduced to the final phase, I went away from him as everyone will have a bad time against him if he awakens in his final phase. I just needed to be away from him for a few meters before finishing him off or I will be obtaining quite a nasty debuff that is pretty nasty on its own rights. Getting it would really ruin your mood.

"INSOLENT INTRUDERS! HOW DARE YOU ALL TO DISTURB THE ETERNAL SLUMBER OF THE PHARAOH!"

Explosions of dark magic appeared on the floor and the pillar I was standing earlier started to melt. It was the right thing to move out before he moves to the next phase. The reason everything melted the moment he went to the last phase is that he release a debuff called [Decay]. It was his exclusive debuff so there is no need for anyone to worry about this debuff. Everything within his vicinity the moment he enters the last phase, he will inflict the [Decay] debuff which melts defenses in armor and decreases health over time. If inflicted with it, the only way to stop it from spreading is to kill the boss.

Since he already released his debuff, time to finish the job.

"DIE! [Rapid Gunfire]!"

The Pharaoh of darkness was still doing some monologue when the bullets hit his head.. It might be a rude way to do but in battle, there is no such thing as rude, the only thing you needed to worry is who wins and who loses.
