1 The fury of tempest. Evolution. Demon summoning l.

Near the border of Blummed. Two individuals are fighting one sidedly

'The hell? I can't fight her at all. Great sage. What do you advice' Said Rimuru. {I do not know what to do in this situation. But i suggest going all out with your skills.}.

Hinata-"Oh finally giving up are you. Fine I'm bored with you and I am sure Shizu is bored too. I will finish this with one attack". "Fine. I will do thi-". Said Rimuru but Hinata did not wait for him to finish talking and. Rimuru wanted to dodge but he was slower than her 'Shit I will die. Help mee-'

Slash.

Rimuru body shined rainbow and feeling immense pain his mind went blank and his body exploded.

"Ugh where am i. I rem- Oh no am i dead? Great sage. Great sageee. What time have i been asleep. Answer me..." {Yes. I am. You have slept for 1 month.} "One month??? More importantly What is this power inside me? Wait where am i. This is. A barrier? I recognize this place. It's Tempest. Oh wait i remember Hinata told me there is war. Great sage can you nullify the effect of the barrier and analyze it?"

{Analysis complete. This is a weakened version of Hinata's barrier. Trying to resist the effects. Complete.} "Perfect." Said Rimuru but he wished he hasn't said it after he entered the barrier. There was many horrible things. by many. i mean MANY. Male Monsters dying. Female monsters get captured to Falmouth. Everybody in his right mind would know why.

Angered by this. he unleashed his maximum aura. "NOO. WHAT. M-" he stopped talking his pale eyes came. He saw Shuna getting carried while Gobzo is dead near her. He immediately went into battle stance and killed them all with great speed invisible to the naked eye.

Upon realization that a monster is here. Monsters in carriage are killed. As this was a order from their superiors himself. Unknowingly this caused the death of shuna and them right after they do it. He killed them all in 5 minutes. {The unique skill 'Merciless' has been gained}. {The unique skill 'Fury' has been gained}. {The-} "JUST SHUT UP" Yelled the monster scaring his near alive soldiers. Not for long though.

Upon finishing his snack of souls. {Checking the Numbers of souls collected. Complete. Evolution to demon lord 'Harvest festival will commence' "Uh what is happening to me. I have the sudden urge to sleep. Demon lord?" said Rimuru as he slept immediately because he checked the area. and it is safe. he still put a barrier with all of his left strength and slept.

{The harvest festival will now commence.}

(This part is skipped he gained all of his skills once he became a demon lord before)

"What no. I know i can gain more power than this. This is not enough. I shall not accepted it".

{Understood. Upon the host will of will. The harvest festival will evolve further with the requirements of more souls and activating the skill 'Merciless'. Agreed}

Raphael-{ Sacrifice the skills of 'Fury'. And 'Berserk'. to evolve the skill 'Beelzebub'}

Voice of the world-{ Understood. sacrificing the skills 'Fury' and Berserk for evolution of 'Beelzebub'. Successful. Beelzebub has evolved to 'Azozoth'. Upon your favor in the ultimate skill 'Azozoth'. Evolving the race demon slime to secret subspecies.True Glutton slime. ( Similar to true dragon ) Evolution tree has changed. End of harvest festival}.

"Where am i. My body is changed somehow". {Congratulations master. You have evolved to a new subspecies 'True glutton slime'. You have slept for 5 Days. When you were asleep i was analyzing and modifying your new skills. O have obtained power called 'Turn null' Energy. I'm in progress of analysing it. 1.5 Hours is needed for complete analyzation.}

{Report: 10 Flying Pegus Knights approaching you in two hours. Falmouth is sending 3000 knights to dispose of you in 4 Days.}

'Wait wait. Calm down a bit. tell me a good report of what happened'. {Understood.}

One hours later of explaining.

'I see. so you made me stronger than a common true dragon (Like veldora and milm) l. and i might be the most powerful not including unknown people i haven't met? Including the primordial guy crimson.'

{Affirmative. But Gaining souls will make you stronger and If you gain enough power. You can evolve again. You see. True Glutton Slime Is weaker than the main evolution you were gonna go because of the rushed evolution and your favor upon Azozoth. But it has more potential so i count that as a win for master. Fufufu}.

"I see. That's perfect. Fufufu

". Mutters Rimuru with a pale face then he smiles devilishly Then cries non emotionally and put his mask. {Warning: The Pegus Knights are coming in 3.2.1 Seconds.".

King Gazel-"Oh Rimuruu. I felt your aura a few days ago and sent spies but i saw you Asleep as i did not disturb you. I heard you evolved as a demon lord. Congratulations." Landed Gazel. Gazel-"I'm sorry I coul-.". Before he continues to speak. Rimuru Slashes him with Turnnull energy and Azozoth to destroy his soul. Surprisingly. king Gazel was fast enough to block it but he knew something was wrong and his weapon got destroyed hitting him a clean hit to his soul. Absorbing it. And before other reacts he absorb their souls too.

"Nice now what to do with bodies". {I suggest Summoning demons and threat them to become your servant. If they don't want to. And no loss as you can gain power from their death if they declines. I suggest Summoning this weird demon that follows you Everywhere you go. He seems to want to serve you. He is a primordial demon who has good experience but not enough power. Which i suggest you name him and make him yours.}.

"Hmm servant?.". "Hmm fine as long as he is not a subordinate and stays away from me as much as possible you can send him this message to him that while I summon him" Says Rimuru as he begins the summoning magic.

Black mist came and came a black haired demon kneeling to his new lord as the black mist disappeared.

Soon to be diablo-"Oh how magnificent my lord has become. I congratulate you in the evolution Milord". "That's enough call me Rimuru. I think you heard of the message so i will skip formalities and others. Your name is diablo. Serve me well.".

"Ohh Rimuru-sama what a magnificent name." As he went through his evolution.. Surprisingly he evolved twice as he needs rest but he delays it for saying "Thank you. Rimuru-sama. I shall live up to your expectations.". As he continues his sleep.

In the cold palace 5 days ago. There was Magicules wave from an aura.

Guy-"What's this aura. it's the same as luminous but it's not her. It's getting stronger every second. I think i know who it is. It reminds me of Milim Toy or bestie. whatever. , It's filled with many emotions. Grief. Anger. Sadness. Depression. Fear. It's a threat at this moment but Milim got really sad about her bestie death so I will keep it. anyway i've been bored for a while this will make things interesting. Plus it things go South I will take care of it." Mutters guy while Velzard doesn't care. If things go South. guy will take care of it.
