My Life in the Multiverse
Poor demon king Leon and Using the path of evolution!

...****************...

As Yuki calmly read through the various requirements of his abilities and the different items they needed to evolve, he noticed that his skills had to be at level 10 before those requirements appeared… and he wasn't sure if he could help others.

'This journey is truly precious' Yuki thought as she lay on the comfortable bed that Leon provided, before her face suddenly changed as she felt a stinging pain in her stomach.

"Ugh, what happened ..." muttered Yuki, and as he did, Leon suddenly appeared out of nowhere in front of him and observed him secretly as a large number of 'magic' as they called in this world which is basically where. it continued to rush into Yuki's body nonstop and his magic core started working at maximum speed to absorb it and control it so as not to rampage in his body.

"You must have received a powerful skill when you were summoned here, which is why your body takes up so much magic, this is the difficulty of everyone summoned here" leon said as he examined Yuki's condition and his face turned serious looking at the terrifying amount of magic he had absorbed like an abyss.

'What kind of skill did this child acquire ... this was already at the level of at least a unique skill' he thought in surprise but he hid it quite well.

"If this continues.I feel like I'm going to explode" Yuki murmured through her gritted teeth as she thought 'Why is this not happening right away... does my body need time to adjust to this skill or is it a world left behind to act …'

"Try to focus on stabilizing your body, I'll summon a spirit to help you control magic" Leon said although he wasn't sure even a larger spirit could save him... but Yuki quickly rejected her kind offer "I don't let you put anything into my body, you disgusting pervert' Yuki thought before she said, "No! get me as much steel as you have as fast as you can, I have a way to deal with this ..."

"Are you sure?" leon asked doubtfully as he stopped his summoning magic and Yuki barely nodded as he used his absolute focus to help regain control over the crazy mana that was trying to overwhelm his body.

But suddenly, though, his balanced magic core began to shine with a white holy light and a terrifying dark light and it began to devour the magic rampaging through him at an even faster speed as a notification appeared in front Yuki's.

...[.Congratulations, you have fulfilled the requirements and unlocked the new abilities of your balanced magic core]...

...[.Balance: allows the host to control mana passively and not allow it to become chaotic in the body and will always keep it in a balanced state!]...

'Good time!' thought Yuki and she felt that her body that was about to explode from the immense pressure of overflowing mana had finally reached a state where she could withstand a little pressure, but this was only thanks to his hard body and unaffected ability However, given the amount of magic he kept absorbing, he would soon be flooded again and explode if he did not take action quickly!

Leon saw that Yuki was actually able to regain his own control dumbfounded, but he waved his hand at him and moved it to one of his warehouses where he kept the Steel.

"If you feel like you will lose control at any time, let me know and I will take action as soon as possible" Leon said as he watched Yuki curiously.

'If this kid can survive through this, he'll be a monster' Leon thought.

Yuki nodded at him before he approached the pile of steel and started devouring it through his path of evolution ability.Yuki watched curiously as the pile of steel turned into light before being absorbed into every inch of his body, and in just a few seconds, 10 tons of steel disappeared into thin air which left Leon dumbfounded..

But Yuki did not stop and went from one pile to another with a happy smile on her face "Well how much I love free food"

Leon didn't feel anything was wrong for now .. but he would soon regret not letting this child in front of him just explode.

After absorbing 150 tons of steel that was more than half of what Leon had in the warehouse, the, yuki's body that continued to gather light suddenly started to glow before slowly subsiding as a new notification appeared in front of him.

...[.Your abilities The stone body has successfully evolved into a steel body]...

'It's more than I expected, but I don't think this steel is 100% pure which is why it takes more than it needs' thought Yuki with a smile on her face as she could feel her body withstand the pressure easily now, and it would be. It was still a long way away until the magicules who were in a hurry could reach her new limit, but it was still too far away, so instead of them nurturing his magic core that absorbed them crazily tried to regain his balance.

But despite all this, Yuki finally muttered as she looked at Leon "It's bad, I might be going to explode if this lasts a long time" but it was different from the expected worried expression on her face, he had a wide smile and it made a shiver. down the backbone of the demon lord.

'What feeling is this?' The frightened Leon thought as Yuki approached him and said, "Leon, do you have any diamonds? Please, I don't think I can last much longer..."

'No kk, this bastard, I feel like he might be able to last longer than he thinks' leon thought before he remembered that this child was only here because he forcefully called her out so he felt guilty, leon moved yuki to another warehouse that was filled to the brim to Yuki's surprise.

"Th-this..." Yuki's eyes shone like never before and he almost started shooting light from them as he stared at all the shining diamonds.

"Don't be surprised, we are located near one of the largest volcanoes in the world, it's natural for us to mine diamonds from it and sell them to other countries, This is actually one of our biggest merchandise." leon said, but Yuki had already made him mute and greedily began to absorb all the diamonds he could, which was the next requirement for his ability of the steel body to evolve again ...

“You... you should not absorb everything.” Said Leon whose heart ached seeing the pile after pile of diamonds disappear from his sight and began to regret his generosity.

Meanwhile, the greedy Yuki continues to absorb the endless abyss-like diamonds while secretly throwing a few chunks into her space ring for later use while thinking "HAHAHAHA, I am rich, I am, suck up your filthy demons, just wait until I get back and I show you who's boss"

After a moment of absorbing, Yuki finally stopped when a new notification appeared in front of him

...[.The host survived, your ability steel body successfully evolved into a diamond body]...

Yuki grinned widely as he felt no matter how much mana flowed in his body, it had no effect at all on him!

'I can't even imagine how strong my defense is right now, especially if we add my unaffected abilities!' thought Yuki happily before she turned to Leon and noticed that she had a very dark expression on her face and could not help but ask, "Leon, buddy, is everything okay?"

Hearing this, Leon clenched his fists so tightly that even the surrounding air trembled slightly before he said, "WE GO NOW!" And waving her hand sent Yuki back to the room in her castle.

'Who told you to keep watching me secretly? You think I would believe that it was a coincidence that you quickly discovered my abnormal state, obviously you were watching me the whole time' thought Yuki who easily found an excuse to justify herself destroying most of a country's economy selfishly.

'By the way, my body is still absorbing mana endlessly and I can feel it somehow changing' thought Yuki before him to sleep with a happy smile on his face when Leon suddenly appeared on it, with his hand the unsheathed sword thought of whether to kill him or not before he finally sighed and left.

However, not long after he was approached by his subordinate Claude the black knight, his strongest knight who immediately said, "My master, What should we do now? We lost a lot because of that brat and we might not be able to do so. offsetting the expenditure especially our large magic core needs to strengthen our formation that we bought from the Sarion Dynasty ..”

Leon's face became darker, only slightly brighter than Claude's black armor as he said, "I'll think of a solution, we can't burden our people with my stupidity... I didn't expect it to finally summon a terrifying Devil."

Claude strongly agreed with the description he nodded before he looked towards Yuki coldly with his unknown thoughts.

------

Early the next morning, Yuki wakes up in her lavishly decorated room with gold and silver and yawns lazily "Ah, this is life" yuki muttered with a happy smile on her face as she stood up from the bed and felt as if today's morning was very windy but she ignored it and leaned her head out the window to observe the big city Eldorado.

It's a work of art, though, a city that can only exist in fairy tales with its streets shining with golden light and perfectly placed houses and careless people walking past it wearing clothes from the 19th century… Yuki felt like she was dreaming.

But suddenly, a beautiful maid entered the room while saying, "Sir, your breakfast is ready" But his eyes suddenly landed on his body and he could not help his words as his face turned red and he quickly ran out of the room while shouting.

"Huh? What's wrong with her?" Yuki muttered before she looked down at her body and finally understood why she felt such a gentle breeze ... She was completely naked, and the poor maid might have finally seen the entrance of the ravine as she leaned against the window.

But that's not what surprised him.

..."Wh-what happened to me... My body, how can it be so perfect?" Yuki muttered confused by what happened as he approached the mirror in the room and observed his appearance carefully.His handsome and clear face, soft flowing white hair, sharp eyebrows, and, and graceful green eyes shine like two emeralds.Note a very muscular but curved body like the best athlete.

Let's just say his eye color is emerald green and there are no eye tattoos....

"What happened to me?" Yuki muttered as he touched his face in a daze as a butler suddenly rushed in with some clothes and said, "Sir, I'm sorry for the servant's reaction, please wear this for now until we provide you with the fitting clothes" said the butler as he handed Yuki the robe and yuki received it in a daze.

"Thank you?" he answered before he said in his mind

'System, please explain to me what kind of magic is this?'

This situation was beyond what his human mind could comprehend.
