Rimuru POV

So I am level 2 know .. I need to speed up my leveling after all in 10 Days Players will come and do everything to level up , i need information , Experience and more skills. 

'So i can defeat a Level 3 Monster .. i hope that will be the case for every Level 3 Monster'

So what i need to do now is.. just exploring and hoping to find some weak monsters that will gain me enough XP. And so i did i found a few Wolve packs and wiped them out. 

[Gained Xp:2300]

[Gained Items: 5x Wolf Fangs of lower Quality ; 1x Wolf Fangs of High Quality ; 2x Wolf Fur of normal Quality]

With this i learned that not every Monster drops something also i found a new type of monster , yeah you are right .. the weakest ones in games normally .. Goblins. Well the problem is this isn't a game for me also I am just a slime at the moment. But the biggest Problem is that they are many and most of them are Level 5. 

'I think this is overkill for me at the moment' 

/Notice: The Race Predator Slime has a few hidding things like you won't receive damgae of normal sword slashes./ 

'Oho so you want to say try it Master he ..Well then let's do it'

[World Quest acquired: Dungeons Part 1 - You have found your first dungeon , Clear it alone or with a Party. Rewards: 5000 XP 2500 Gold] 

[Dungeon Name: Depths of The Green Monsters Difficulty: Beginner 

Suggested Level: Level 10] 

[You are the first player who found this Dungeon. Items drop chance increased: 

High Class Item - 20% ; Top Class Item - 5% ; Legacy Class Item - 1%]

/Wait Wait Wait too much Information .. Level 10..? Item Drop chancen increased..? Ciel how much Item classes exists in this World?/

/Answer: 9 , Low Class , Middle Class , High Class , Top Class , Legacy Class , Relic Class , Legendary Class , Divine Class and the so called World Items./

'Well lets think about that stuff later and firstly kill these Goblins' 

I activated my Magic Acid Arrow that now thanks to my Invested Skillpoint in Wizard 3 Arrows and not one creates and aimed at the goblins. After they got poisened i eated one after another .. against dumb monsters this technik is really good. 

After i killed the 5 Goblins that were outside the dungeon i waited and restored my MP , well Ciel was right that swords like that and simple slashes don't deal any damage to me I am so lucky. 

/Master you reached level 4/ 

/Ahh Ciel since i've only 2 options just put one in Predator Slime and then the next in Wizard and so on/

/Affirmativ./ 

After i restored my Mana i entered the Dungeon .. and i must say it's not what i thought it was. I awaited a cave with a few Goblins. And not a well build underground dungeon with Goblins and Undead Goblin Skeleton. 

'It's good that Acid attacks are effektiv against Skeletons of any Race. Then let's think abaout a way to go to the boss Room' 

And so I fought my way through the dungeon with my Acid attacks after 30 Minutes i found a chest and opened it. 

[High Class Item : Dark Cloak received:(If equipped) 

- Passiv: it will supress your Footsteps for Monsters and Player under or at the same level of yours. Hides your Identity to Players at or under your Level.

-Activate: Can select players to show your identity even if equipped.]

'That seems rather nice i should keep that , Inventory' Ciel opened my Inventory like always and i stored it inside. 

'I haven't become on drop of the monsters it seems the drops will be gained after leaving this Dungeon.'

I also could feel that I've become stronger. So i went deeper in the Dungeon. 

I've killed a huge amount of monsters on my way to the door that seems to be the boss room door. I haven't even lost one HP but that's only because I am lucky all in this Dungeon has a weak point against my Race and Skills. Would it be other monsters i would be long dead. 

'No risk no fun he? Let's go inside' as i rolled over to the door it opened itselfs and i could see the boss monster. 

Goblin Shaman - Level 12 

So i entered the Boss room and the Goblin in front of me instantly fired spells at me , most likley some sort of Thunder Magic.

'I need to dodge this attacks I am sure one hit would be enough to kill me' and so i tried my best to avoid this attacks and as i saw a opening i once again began to attack with my Acid Magic attacks .. they are way stronger. 

'Ciel must have invested Skill points in Wizzard' i thought and continue this long lasting fight

'It's time that you will die !' i shouted in my thoughts and attacked him with my Acid stomach attack until his last HP fadet away

'Puhh .. that was harder then i thought so let's see what you've dropped hehe' 

But before i Could loot the Items i received a shocking message.

[Congratulations you have cleared the Dungeon and activated the secret Quest of this Dungeon]

[Requirment to activate the Secret Quest: Clear the entire dungeon without losing any HP. (Accomplished) Secret Quest started :Kill the Demon Shaman Rewards: 3 Top Class Items 10000XP]

'Oi Oi Oi! Why is the game suddenly so hard and whats with that rewards 10000 XP ..? well i don't have the time to think about that. What's with that Monster!!!!' 

Demon Shaman - Level 30 

'What is going on here ?!' as i saw he is casting a spell i luckily dodged that. 

'Wait this was Black lightning eeeehhhh?' I was really supriesed he could use that

/Ciel! Help me !/ i shouted

/You've gained a lot of new skills anyways they won't do anything against this Demon they are usless , I suggest to use Acid stomach the monster isn't a Hand or Close-Combat type./

'As Always she is right .. why didn't i thought abaout this? The monster just can cast spells and it wouldn't want to attack itselfs with the attacks.'

/Of course I am right fufu/ do i hear her giggls ?? 

Just as Ciel said i attacked the Demon shaman with my Acid Stomach and he couldn't do anything against it. 

[You have cleared the Secret Quest of the Dungeon Depths of The Green Monsters]

[Rewards: 15.000 XP 2.500 Gold 3 Top Class Items]

'That's way to op! well i guess for the start. 6th Tier Magic whats that?'

/Magic in this World is divided in 11 Ranks 1 Tier until 11 Tier Magic/ 

/I understand thank you Ciel/

/You are welcome Master, Anyways you were now 4 Days in this Dungeon you should visit a town after all you can now use Shapeshift/ 

/I can turn into a human??/ i asked suprised

/Affirmativ/

'then lets try it out' and so i used my Shapeshift skill to form into a human.

'Oh I am naked .. i should equip my Items' And so i put on the Demonic Set and my Cloak . 'fufu I am really looking like an high level NPC'

'Wait .. can i speak?' i thought and opend my Mouth

"H-Hello? YEAAAHHH i can talk , nice!!" i shouted happy

"Fufu now we can go to a Human Town!"
