Leon who's falling fast in the darkness all of sudden his body then stop falling and hears a mechanical voice in his ears.
[Initiating sequence, scanning the master's body....1....30...69....100% completed, Hello master, I'm a system name Multiverse created by #### the spirit inside the system accepted you but it didn't have the capability to have an emotion so the system needs the master to be the one who will choose its gender, personalities.]
"First of all, what are you? and why are you in my head? is it just like those parasite systems, who controls the protagonist life and give death penalties?" Leon cautiously think and continue to throw questions at this so called Multiverse system.
[Of course not master please don't compare to those parasite system, as for what am I, just think that I am a special system, I'm in your head because I'm one of your boons and I can't tell you the other reason.] the system coldly said with a little bit of tsundere from who knows where it got that.
"Why aren't you allowed to tell me that?" Leon said while sitting on the non existing ground.
[Master it will better for you to know the reason it might regret it to learn the truths and even I tell you everything you might not get it.] the mechanical voice said coldly at him.
"O-okay...is there's more anything besides you?" Leon wryly smiled then remembered what the goddess Aurora said to him.
[...Yes master, its a blood of a primordial being it has seven transformations, it called Seven primordial dragon blood, their clan only has 30 members in it, it existed eons ago and rule over all the dragons from land to sea in the primordial age. However they didn't last long because they provoked a being and that being killed all those dragons with cruelty.] the mechanical voice coldly said and take out green vial that extrudes majestic aura and bloodlust, Leon who felt the strong bloodlust his body began to tremble but all of sudden the bloodlust inside vial suppressed by the system.
"Why that being killed them what's the reason!?" Leon got shocked and curious because of its history and why such powerful dragons got killed by a single being.
[ Its the #### the one killed them, the reason is #####...] the system said coldly to Leon and he couldn't understand anything that the mechanical voice just now.
"Why..why I couldn't hear anything you just said?" Leon confusedly said.
[Looks like the Creator didn't allowed you to hear] the system coldly said and Leon just sighed.
[Now master please choose the system's gender and personalities] the system said coldly while a transparent panel appear in front of him and message appeared in the panel.
[What gender do you want? Male or Female] Leon then select the 'Female' button after that the message disappeared and another message appear.
[Please choose 3 personalities for the system's spirit
Loving
Supportive
...
Positive
Tsundere
...
Yandere
Goudere
Masochist]
[Please choose wisely]
Leon then selects the 'Loving, Supportive, Positive' personalities then click a button to finish it off.
[Thank you for your cooperation master, please wait a moment...] the mechanical voice sounded in his ears again.
[...Why hello there master, would you like to give me name] Leon then heard a female voice with an excited tone
"Hmm...okay...your name is now Iris" Leon nodded and think a name that would suit her.
[Thank you master for naming me, now you should absorb the dragon blood, don't worry master you will be safe when absorbing that dragon blood because the system will help you] Iris said positively, Leon then nodded and recklessly drink the dragon blood.
After that the system then help Leon absorbing the blood 10 minutes after the void energy suddenly envelop him and the energy made a dark with little twinkly stars egg. After 20 mins the egg starts to get bigger up to 10 meters then after 1 hour the egg is already at 300 meters another 1 hour was spent the egg then stopped at 500 meters. After 30 mins the egg starts to crack from the top then spread out. Then reveal a 500 meters black dragon with stars in the scales, the dragon then spread its giant 2 pairs of wings and let out a loud roar that travels around the void. Far away from Leon all void beasts began to tremble because of the sudden roar. For them its like announcing that the void dragons are back and will rule again the void.
After 2 minutes, Leon who let an unconscious roar woke up then look around of course he saw nothing but an endless darkness. He felt that his body became strong like never before he look at his got shocked.
"Wha-what the heck why did I got bigger and have 4 wings?" Leon tries to move his dragon hand but it didn't move.
[Its because you became a dragon you dumb master] Iris said and then a transparent panel appeared then a face pout and continue talking.
[Your first transformation is called void dragon because you spent 500 million years in void, the void dragon in the Seven primordial dragon was easily incorporated in your body] Iris explained to him.
(A/N: hehe...shh...(. ❛ ᴗ ❛.))
"Okay then thank you Iris" Leon was little shocked and try again to move his dragon parts hands, wings, feet, and tail. And so he spend 1 hour practicing his dragon body.
[Master its about time you go to Tensei Shitara slime Datta Ken world] Iris said excitedly to Leon who's in human form.
"So...its...that world is that slime going to be there?" Leon remembered the anime since its his favourite after all....😏.
[Negative...that slime will not be there, the system remove that genderless reincarnated slime] Iris said angrily to Leon. (A/N: I don't know why she said that angrily..¯\_(ツ)_/¯)
[Master your current body will disappear and your soul will transfer to another body] Iris remind him.
"Okay Iris lets proceed shall we?" then Leon continue to fall and became a shining star because how fast he fall and disappear in thin air.
=========
Somewhere from the Sky a huge Island floating above the clouds.
"Look how cute our baby is" said a voluptuous woman with a silver hair, violet eyes and wearing a one piece dark dress if somebody would see her happily he/she will be in bewilderment because of her frightening cold look, while holding the baby lovingly.
"Oh look our baby is waking up" said by a middle age man with an average look, black hair, gold eyes, while he happily smile at the baby.
(A/N: I'm lazy to write his full appearance not like...😊)
The baby aka Leon open his eyes slowly just like when waking up from sleep.
He see a beautiful woman smiling at him while she look at him joyfully. Leon slightly turn his head then see an average looking man smiling at him.
'So I sucessfully entered the world but somehow its different from the light novel & anime' Leon said in his mind while observing his new parents since both of them aren't in the light novel and in the anime too.
[Your correct master its an Alternate Universe its different from what you know also things might get harder since this world is different...but you can do it master I believe in you] Iris said like a supportive girlfriend.
'Thank you Iris for your support' Leon said to Iris and said welcome to him then he hears something that shock him.
"Ah yes, babies need to drink milk right?" ask by his mother to the maid near them, she ask because this is her first time to become a mother.
"Yes, milady...now if you will milord" the maid answered then look at Leon's father and said to him while she opens the door then the father walk outside without complaining and she also walk outside of the room.
"Now..how do I do this...ah yes" she sit down on a comfy sofa and think what next step is she then move her strap and her huge breast revealed in front of Leon after that she moves Leon's head near her breast.
'What a huge breast you got there mother 😏 *cough* I mean do I have to this?' Leon complement his mother huge breast asks Iris since he has mental age of 22 he hesitant whether to do it or not.
[Yes master you have to do it for your mother's sake] Iris convincingly said to him and didn't even bother the complement.
'Okay' Leon mentally sighed then opens his small teethless mouth then suck his mother's nipple.
"Ahn" Leon hear a muffled voice and ignore it then continue his sucking. Of course that muffled voice is from his mother, it was her first time after all...(A/N I used my authority and forbid that average man from sucking her breasts...¯\_(ツ)_/¯)
Just like a baby after finishing its Leon sleep in his mother's embrace while smiling.
"Fufufu I, Lily Walker, as your mother will love you and protect you even you become a rebellious brat" Lily swear to Leon and she stand up and place him on the bed....
[Quite cringy I must say but...meh] Iris unconsciously said.
