Inside the Ravenclaw tower, Luke burrowed into his room and Edward fell back into a deep sleep, but he lay in bed and squinted for a moment before the Head Girl, Penelope Krivat, came to the door.

"Luke Harris! How dare you tackle a troll at such a young age? I just heard Edward say you weren't there during roll call causing me to look all over for you! Only to hear later from the professor that you actually solved the troll all by yourself!" Penelo spotted Luke, and as an honours student who was rarely criticised by her professors, the pretty girl was obviously a little freaked out, and walked quickly over to Luke with her teeth and claws open.

"I just happened to have a stomach upset and happened to encounter a troll on my way to the feast, so please spare me for the sake of adding another 20 points to my Ravenclaw score, I'm a victim too! Besides, Miss Krivat you're even more beautifully dressed than usual today!" Luke threw his hands up in surrender and changed the subject very effectively.

"You're a Ravenclaw not a reckless lion! Next time, but I have to say, you impressed me by being able to tackle a troll on your own in first year. Also, the Dean has asked me to inform you that now that the troll incident has been resolved, the Halloween revelry will continue and we Ravenclaws will be having a masquerade ball by the Black Lake." Penelope beamed, "With the other three houses continuing their events in the common room, I thought Ravenclaw needed to be a little different and proposed holding it by the lake, not realising that we had the strong support of Professor Flivvy, who will personally ensure our safety. You look out of the common room window later, all these lamps in the sky are enchanted by Professor Flivvy. The girls loved the offer and contributed a lot of silk scarves, but alas Headmaster Dumbledore apparently had things to do and he declined our invitation." Penelope's tone grew excited.

Luke felt that the Penelope in front of him was a little different from how she usually acted, the teenager always had countless whimsical ideas in her head, even if it usually seemed that she gave off a rather difficult feeling.

The Ravenclaw wizards regrouped and quickly made their way to the lakeside, the reflection of the huge castle was reflected in the clear water of the lake, the trees along the lakeside were covered in colourful lights, many different shapes of coloured lights were floating in the air. Many long tables were placed in a U-shape on the grass by the lake, the tables were covered with light blue tablecloths, and a large amount of food was placed on the long tables for the students to enjoy at their own discretion. Many white Romanesque chairs with backrests were scattered across the grass, long ribbons tied to them waving in the wind. Some of the young wizards were sitting on the ground around a roaring bonfire; some were walking in groups around the lake; others were setting off fireworks in the distance, the bright fireworks illuminating the night sky and their cheerful smiling faces - obviously they didn't realise at the moment how the trolls had been dealt with.

And surprisingly, this area by the lake didn't feel cold; it must have taken some effort on Professor Flivvy's part to set up a thermostatic spell here in a short period of time.

Luke even saw Lady Grey amongst the revellers, her expression was cold as ever but she was floating amongst the fluttering silk scarves and seemed to be immersed in the fabulous party as well. The statue of Rowena Ravenclaw was obviously unguarded then, and the thought of the empty common room he had just seen made Luke's mind reel.

The narrative has been stolen; if detected on Amazon, report the infringement.

Having just arrived at the party grounds he quickly doubled back and rushed back to the common room after adding an illusion spell to himself in the corner, Luke checked around a little to make sure no one was here and quickly made his way to the statue of Rowena Ravenclaw, although he had already surmised that the statue was hollow, Luke didn't look like there were any gaps in the statue as far as he could tell from left to right. Luke even got down at Ravenclaw's feet to look up her skirt ......

Luke couldn't make sense of it for a moment, and looked around carefully again, and finally he was staring at the top of Rowena Ravenclaw's head when Rowena's long curved hair swirled in a beautiful arc on top of her head, an arc that was very familiar - thinking of the last time Lady Grey had talked to him, the crown on top of Ravenclaw's head suddenly came into his mind and Luke a clapped his hands, wasn't this arc exactly the shape of a crown.

Assuming that there was a crown that just happened to be set seamlessly in place, the two crowns just happened to form a complete crown. So, the next thing to do is to find the real crown.

Luke of course knew where the crown was, the Ravenclaw crown was now in the Room of Requirement, being crafted into a Horcrux by the Mysterons, he vaguely remembered it being on a statue of an ugly old wizard, he just wasn't sure that the tainted crown would still be able to open the statue.

Casting the illusion spell again, Luke ran familiarly up to the eighth floor of the castle, stopping in front of the mural with the gargoyle hanging, holding his breath, clearing his mind, and thinking only, "I need a place to hide something." After three silent recitations of the walk, the entrance to the Room of Requirement appeared.

Luke stepped inside, which was densely packed with bottles and jars, tattered textbooks, strange looking robes and other assorted oddities, he nodded in satisfaction, intending to see if he wanted to wait for the holidays to pick something less dangerous to take out and sell for some pocket money ......

Suddenly a strange smell came, Luke finally determined that it was from the hidden door of a huge cabinet, Luke raised his wand, slowly walked over and pulled it with his left hand, the cabinet door was wide open, glimpsed what was hidden inside, Luke's face changed - I don't know who, actually in such a short time, made that gargoyle that was just there into a specimen, soaked it in the water, and then put it in the water. into a specimen and soaked it in antiseptic magic potion, and the stick in its hand was actually inside!

To quickly find the crown and get out of here, maybe the person who made the troll into a specimen hasn't left here yet, Luke accelerated the speed of search.

Soon, Luke found a stone statue of an old wizard with pockmarks, wearing a dirty tattered curl and what looked like an ancient faded crown. This was it! Luke quickly scurried over to the crown, and to avoid having his mind disturbed by the crown that had become the Mystic's soul weapon, he ran the Brain Closure spell at full power, and carefully used his wand to levitate the crown through the air and drop it into the system's complimentary storage space.

"Broken soul found, host please note that living things with souls cannot be loaded into the system storage space, sure you want to store it?" The system had been out of sight for a long time since the last time it released a mission.

"May I ask what will happen if I insist on putting it into the storage space?" Luke was curious about the result, and had a vague guess in his mind that either it wouldn't fit in, or the soul fragments left in it that the mysterious person used to make soul weapons would be disposed of...

"If the host insists on putting in a living thing, the system will separate out the pieces of the soul weapon and wait for them to be converted into pure energy for the system to absorb and use. However, the host will not receive any rewards for the energy gained in this manner - it should be noted that only living things that cannot resist can be stowed in the storage space." The system's ethereal voice carried no trace of emotion.
