Dungeon Lord and not Dungeon Master!?

Hi, I'm Sora I'm somehow the mc of this story, I'm gonna tell you a weird, super weird story! I died today but for some reason, I was not in heaven, then hell it is right? but it wasn't either I'm inside a fcking dungeon in a fantasy world! and you ask me why I know all this just because there is this "System" that explains everything to me, and now here I am in an underground room standing and looking at this system.

[ This is the system, you have been brought here for a reason, from now on you will become a dungeon master, lead this dungeon and live your life to the fullest, we don't restrict you or anything, you can kill humans without being punished if you have a question you can ask me ] and that's what it said

「 but damn, this room is full of nothing, just an empty dark room, it's plain and only has dirt on it, how do you want me to survive with this? 」

[ By using the system you can buy whatever you want, using dungeon points you can pick whatever you want from the system, you have been given 100 dungeon points for a beginners pack ]

「 hoh? aren't I amazing! let me see this system then, let's see Ummm... System 」 The blue panel appeared! 「 Let's see... so this is me 」 it was my character in this world, 「 hoh hoh, Aren't I handsome? I still have my black hair, also I'm again in an 18 year old body. wow nice nice! being in that old body is tiring! let's see, my title is Dungeon Lord huh like the system said 」

「 But... isn't it supposed to be dungeon master? No answer huh... whatever, I still have my old clothes on huh, wearing a business suit in a dungeon that is a bad matchup 」 I look around the system more, and I found the "Shop" It can buy me everything including the things from my world oh? there are still begginers pack huh it's free so let me buy it.

Suddenly, the room turned into a first-class hotel room,「 How luxurious 」The room is wide, enough for me to stay in, there are even clothes in the closet, let me wear this, It was a jogger and a T-shirt, What do you want? I'm in my new house now so let me feel comfortable at least! Sitting on this bed is bliss! I have never thought I can live in a room like this, while looking around I noticed this TV that is in front of the bed 「 A tv? Is it even working? 」 I switch it open and it doesn't work, huh what did I expect?

「Hah... I guess I need to think about this seriously huh, I'm a Dungeon Lord a villain, or a monster either way someone will for sure come here and kill me, in the manga I read there should be an Orb I need to protect but... there's none here, The system won't say a thing about it either So that leads to me the dungeon lord I need to get killed for this dungeon to destroyed, I don't know where my location is and I don't even know a thing about the outside world, man this is tiring 」As I lie down the bed.

For now, I guess I need to gather Dungeon Points to survive, Ah, how can I even gather dungeon points in the first place?

[ Notice to gain dungeon points It has three ways, First let a human inside your dungeon from that you can earn dungeon points, second by expanding your dungeon and having the monster you bought in the system get killed you will earn dungeon points, Lastly by killing a human, this will let you generate lots of points please do not feel bad about killing your monster nor killing a human, they all want to kill you this world is survival to the fittest if you're weak the monster you summoned will kill you and get the title of the dungeon master ]

「 Damn, this world is crazy, Kill or get killed huh, that's harsh, but for me who never had a chance to enjoy my life... I will do anything for me to enjoy myself! no matter what it takes! and for those who get in my path will get killed without a second thought, I Sora! will promise myself that this day I will enjoy my life to the fullest! whatever It takes! 」
