From Hogwarts to Strixhaven.

Chapter 76 Mordenkainen's Private Chamber

"I never thought the Room of Requirement would be breached one day." Ivy sighed sadly as he stood in front of the tapestry depicting the troll beating Barnabas to death on the eighth floor of the castle. "I've kept so many magical creatures in there over a hundred years ago, and nothing serious has happened."

In fact, there is an example of the Room of Requirement being broken into in the original book.

The Room of Requirement first appeared when Dumbledore was chatting with Harry. He said that when he passed that corridor, he was in a hurry to go to the toilet, but ended up walking into a room full of exquisite chamber pots.

Later in the fifth film, Harry Potter and the Order of the Phoenix, Harry and his friends urgently needed a place to practice Defense Against the Dark Arts, so Dobby, who was hired by Dumbledore to work in the Hogwarts kitchen, recommended the Room of Requirement to them. So Harry gathered his friends and formed Dumbledore's Army in the Room of Requirement, abbreviated as DA.

As the DA grew, they couldn't all crowd into the eighth-floor corridor at once, as that would have drawn too much attention. So they had to enter the Room of Requirement in batches. Fortunately, when someone was using the Room of Requirement, as long as they were using the same room as the people already inside, the next person could also enter.

Later, during Harry's sixth year, Malfoy was hiding in the Room of Requirement while repairing the Vanishing Cabinet, attempting to allow the Death Eaters to enter Hogwarts through another Vanishing Cabinet in Borgin and Burke's. Harry, needing to hide the Half-Blood Prince's Potions Book, encountered Malfoy in the Room of Requirement. This was the second instance in the novels where someone entered the Room of Requirement while someone was already inside.

There was a third incident. During the Battle of Hogwarts in Book 7, Harry and his friends went to the Room of Requirement to search for Ravenclaw's Diadem. Malfoy and his friends, using the Disillusionment Charm, followed them. After Harry and his friends entered the Room of Requirement, they followed them in. Later, Crabbe used the Fiendfyre Charm to set the entire Room of Requirement ablaze, indirectly destroying one of Voldemort's Horcruxes.

In fact, the Room of Requirement was originally a room open to all teachers and students in the school. Ivy had no way of turning it into his own secret room, even though he had used that room for a long time more than a hundred years ago.

As soon as Ivy returned to Hogwarts Castle, he went to the Room of Requirement to visit his pets.

Whether it was that the entire Room of Requirement was filled with magical creatures, or that Dicko left a letter and moved the magical creatures inside to another place, Ivy could actually accept it.

However, things did not develop in the direction he had imagined.

His luxurious single lounge with soft lighting, which connected four unique terrains suitable for the lives of magical creatures, was gone.

It's literally gone.

No matter how hard Ivy tried, no matter how many dents he made on the eighth-floor floor of the castle, he couldn't find his former personal space again in the Room of Requirement.

If the Tome of Destruction had not clearly displayed various materials from magical beasts, he would have almost thought that the magical beasts kept in the Room of Requirement were just a dream of his.

Add to that the fact that the Room of Requirement had been breached by a first-year girl yesterday, and the Art Elemental Garden Statue Creation ritual, which had cost countless energy and experience points, had nearly failed. Now, Ivy had begun to distrust the room across from the tapestry.

"Howling Flame." Ivy called softly. The bright red cat that was circling at his feet had disappeared, but through the connection between the mage and the pet, Ivy knew very well where the vigilant cat was.

He feigned indifference, whispering the big cat's name as he tiptoed towards a suit of metal armor in the corridor. Xiao Yan somehow slipped into the empty chest cavity of the metal armor.

Ivy estimated the distance, leaped up, and pounced on the armor: "I got you!"

However, the sudden burst of fire blew the armor into pieces, and Xiaoyan flashed to another place along with the fire.

That was Howling Flame's spell-like ability as an Elemental Avatar—Fire Leap. When Howling Flame unleashes this ability, a burst of sparks erupts at its current location, dealing fire damage to all within 5 feet. Then, Howling Flame briefly transforms into a fire elemental and moves to an unoccupied space within 30 feet. Howling Flame's playful and curious nature stems largely from the wind and fire elementals within its ceramic form, not from any genuine dislike for Ivy. It's like a cat or dog trying to chase the mop while you're mopping the floor.

"Interesting." Ivy narrowed his eyes. He regarded Xiaoyan's attitude as a challenge.

Then Ivy used the 1st-level spells Longstride and Grease to increase his movement speed, and then used Cat's Grace to enhance his agility and reaction speed. He was determined to arrest the bad cat Xiaoyan according to the law today, in this corridor!

After a chaotic chase, Ivey succeeded.

After all, Xiaoyan was an Art Elemental he had personally created, and was also his mage pet. How could he possibly go against his master's wishes? As the saying goes, even willfulness has its limits.

"Yeah, good cat~good cat." Ivy's fingertips shuttled through Xiaoyan's gorgeous collar, bringing out sparks. Xiaoyan, who was tickled, also showed an expression of enjoyment and made a pleasant purring sound.

"Very good, Xiaoyan." Ivy's heart, which had been restless because he couldn't pet the cat, finally calmed down. He held Xiaoyan in his hand and said seriously, "I have a task for you. A long-term task."

After yesterday's Art Element Creation Ceremony, Ivy's Scribe Wizard gained some experience points, although it did not mean that he could reach level 9 and cast 5th-level spells. But he could still spend these experience points to select one or two useful spells from the Destruction Grimoire.

After careful consideration, Ivy chose two 4th-level spells.

They are the Miraculous Works of Transmutation and the Mordenkainen Private Chamber of Protection.

The former allows Ivy to directly transform unprocessed raw materials into finished products made of the same materials. Unlike the wizards' transfiguration spells, the effect of the magical craftsmanship is permanent, which is equivalent to using magic to replace the process of manufacturing items.

Ivy plans to use this spell to reduce the time it takes to create magical items.

As for Mordenkainen's private chamber, it allows Ivy to use magic to protect a cubic area, blocking teleportation spells, blocking prophecy and various forms of scrying magic, and also isolating sound and sight.

As long as Ivy chooses a suitable area, then under the effect of this spell, he will have a secret room in the true sense.

Of course, Mordenkainen's Private Chamber, like any other spell, has a duration, lasting 24 hours, or a full day. However, if the spell is cast daily in the same location for a year, the effect becomes permanent.

As Ivy's mage pet, Howling Flame's connection with him is much closer than imagined, so much so that Ivy can lend it some of his own spell slots.

Therefore, in order to create a chamber of secrets that truly belonged to him in Hogwarts, Ivy decided to let Howling Flame cast the fourth-level spell of Mordenkainen's Private Chamber in Hogwarts on his behalf when he was unable to escape.

As for the location of the Chamber of Secrets, Ivy had already chosen it: the Map Chamber at the very bottom of the castle. There was plenty of space there, and the surrounding walls were well expandable. If Ivy wanted to, he could dig out a subterranean castle just like Hogwarts.

This time, Ivy went to the Room of Requirement to find some useful furniture. If she used Transfiguration, who knows when the "Spell Stop" would be cast, and the underground chamber would be filled with all kinds of messy junk.
