Hogwarts : leveling up the world

While Harry was recovering and Asmodeus spent time in the library absorbing knowledge through the system and occasionally strolling with Hermione.

Dumbledore, Grindelwald, and other elders were extremely busy. Asmodeus' requirements for the future academy were too high, and they didn't even know where to start construction.

"Gellert, we need to start construction... you know, the academy is supposed to admit its first students in 9 months, and we haven't even begun building the main castle."

"Go tell that to Asmodeus! Damn him, who wrote this plan? What the hell is this magical creature breeding plan? What are those magical towers around the castle? And why did he mention 45,000 students!!!!" Grindelwald responded with frustration to Dumbledore.

"Ahem, ahem... I really don't want to see him lately. I have a feeling he's targeting my beard; I don't know why, but I have this premonition that he wants to do something with it."

"..."

"And because of that, you don't want to consult with him!"

"Alright, alright. Calm down; we really need to start construction. And I finally understood what those mage towers he was talking about are." Nicolas intervened in the conversation.

"???" Two gazes fell upon him.

"Ahem, ahem, mage towers - in ancient times, wizards built them for conducting research. It was like a home for powerful wizards. Each floor had a different purpose... but they haven't been built for a long time because during the witch hunts, many of such towers were destroyed, and the Muggle expulsion spell didn't exist yet... so wizards gradually stopped building them. Also, with the advent of magic schools, wizards stopped living ascetically and gradually began forming villages. The towers were used so long ago that even I didn't know about them until I found it in an ancient magical book from the times of Merlin."

"Why does he need it in the school!"

"I don't know. Our task is to build a tower; I've already contacted Asmodeus, and he said he'll enchant and improve them himself later."

"Alright then..."

"So, shall we start with the main castle?"

"Yes, it's time to begin construction."

"Will the main entrance be in the southeast?"

"Yes, Asmodeus said he doesn't care; if it makes it easier for wizards, we can arrange the castle however we want."

"Then in the southeast, there's a cliff to the north, and to climb from that side, we'll need to build stairs. So, it's better to place the entrance facing that lowland."

"Ah, so much work... why are we working while he's relaxing at Hogwarts?"

Ah, three consecutive sighs echoed.

Amidst sorrow and frustration, the construction of the future center of the world began.

While the elders worked, Asmodeus, having spent over 1000 points on comprehensive learning in all available subjects at Hogwarts, lay on his bed, digesting knowledge.

"Ah, my head hurts. But now I understand the magic of this world as well as Dumbledore and Grindelwald."

"Alright, I should probably see what the system has to offer."

"System! Open the trading center."

"Ding, at the host's request, the trading center is open."

Infront of Asmodeus' eyes appeared the familiar 4x4 grid where he had bought a set of books months ago to transform Muggles into wizards.

"Sort out only what I can afford to buy!"

"Ding, the host's balance is 15,345 points. Removing offers from the trading center that exceed this price."

"Potion of Pet Development - 700 points. Allows maximum acceleration of pet growth and unleashes its full potential."

"Guide to Pyromancy in the world of SAILOR MOON. The ability to gain insight into a question or situation using fire/heat. Sub-power of Fire Magic. Technique of Fire Manipulation. Variation of Elemental Divination. - 3,000 points."

"Hell-Fire Magic - IFRIT - Ability to use hellfire magic. Form of Magic. Variation of fire magic and manipulation of infernal flames. Opposite of Sacred Fire Magic - 15,000 points."

"Holy-Fire Magic - ZELDA - The power to use holy fire-related magic. Form of Magic. Variation of Fire Magic and Holy Fire Manipulation. Opposite to Hell-Fire Magic. - 15,000 points."

"Potion of Lineage Fusion - 5,000 points."

"Lineage of the Vermilion Family (Black Clover) - 15,000 points."

"Fire Elementalization. Allows the user to take the form of a fire elemental. In this state, physical attacks do not affect the user. Fire magic damage is increased by 20% in the elementalized state. Fire magic consumes 15% less mana. Control over flames is increased by 50% - 5,500 points. Note: minimum requirement for elementalization is 1,000 points of mana for the owner, mana is not consumed all at once but gradually until the host returns to normal state."

"Current mana reserve of the host - 1,250, meets the requirements."

"Small potion of permanent mana increase by 100 points, price - 1,000 points. One person can take only 3 potions per year, developing resistance to the potion after 9 bottles."

"Small potion of physique reinforcement - increases all basic body characteristics by 5 points, price - 1,000 points. One person can take only 3 potions per year, developing resistance to the potion after 9 bottles."

"1 level World Enhancement - 10,000 points. Raises the world level once. Improvement in all aspects - the amount of mana in the air, its quality, the physical preparation of average beings in the world, magical creatures becoming stronger and etc."

"Angel's Tear Potion - brings the deceased back to life if no more than a year has passed - 5,000 points."

"World Level Increase, by half a level. - price 5,000 points."

With the constant flickering of products Infront of his eyes, Asmodeus feared an epileptic seizure. However, he had already chosen the items he wanted to buy.

"Buy Flame Elementalization, Small Potion of Permanent Mana Increase x3, and Small Potion of Physique Reinforcement x1."

"Ding, confirming the operation... deducted 9,000 points. Current balance - 6,345 points. Thank you for your purchase!"

With the sound of the system, Asmodeus felt that something in his body begin to change. Before he could do anything, he lost consciousness.

After a couple of hours, Asmodeus woke up and attempted to stand up from the floor.

"Ugh, my head is splitting, damn it, my whole body is convulsing... *hiss*... maybe I shouldn't have... ah, I'm falling... or not falling..."

As Asmodeus tried to get back on his feet, he slipped, but before he could fall, he involuntarily transformed into an elemental.

"Convenient..."
