With one last burst of mad laughter, Professor Frost's entire body froze completely.

The dark clouds in the sky began to slowly dissipate, and thin pieces of sunlight spilled through the dappled clouds. Although it was close to dusk, they still felt the warmth they had not felt for a long time.

"He's coming......" Professor Frost's words seemed to echo through the valley along with her maniacal laughter, making Allen's scalp tingle.

"Looks like we're in big trouble...... Cynthia reluctantly stood up, gesturing Alan to look at her feet, "but hopefully it won't be any harder than the one at the moment." ”

There was a rustling sound from beneath his feet, and Alan realized that the ice on the lake was slowly crumbling without the magical support of Professor Frost.

"I don't want to sink into the water with this old woman. Cynthia said. But now she is extremely weak, let alone running, even if she walks faster, she will be out of breath, and it will definitely be too late to run to the shore.

But it's good to have Alyssa.

She did seem to have learned a lot from Professor Frost. She was standing not far away, and she noticed this, and in an instant she paved a path with ice blocks from Alan's feet to the shore.

Alyssa was the first to go ashore, with Mary in her arms, and Ellen followed with Cynthia in her arms. The frozen Professor Frost and the soul-sucking lamp both sank into the Crescent Lake.

The snowflakes that had wrapped around Riel were gone, and now he was lying on the ground, motionless.

Alan ran over quickly, tested it with his hand, and was relieved to find that there was still a snort.

Alan told Cynthia to rest where she was, and she ran back to the cave to check on Frey, and when she found that he was like Riel, she used the Levitation Charm to move Frey out.

"I remember you......" When Alan came out, Alyssa was chatting with Cynthia, who was resting on the rock, "You're a friend of Ellen, aren't you?"

Cynthia was stunned, and Alyssa still didn't seem to know her.

It was Alan who reacted first, and part of Alyssa's soul was still sealed in Mary's tail, and those memories about Cynthia may have also been sealed inside.

But it was much better than what they had expected at first.

"It's good if you could come back......" Alan said with relief as he walked over, even with tears in his eyes, "I thought I'd never see you again......"

"What are you talking about?" Alyssa looked at Alan with a confused expression, "Why can't I understand......"

Alan was stunned: "Don't you know what's going on?"

"I just feel like I've had a good night's sleep......" Alyssa shook her head, "and it's been a long sleep......"

"Then you just ......," Alan said again.

"Ah...... That's it......" Alyssa understood, and slowly recalled, "I don't know when I started thinking that another me had appeared in my body, and I had been thinking about how to kill you...... I was so frightened that I tried to kick her out, but she locked me in a dark room...... At first I thought I was dreaming, but I could clearly see that my body was hurting you uncontrollably, and although I felt sad, I couldn't do anything about it......"

Alan nodded, this is exactly what Professor Frost said before, her soul has been entrenched in Alyssa's body, suppressing Alyssa's consciousness.

"After a while, suddenly a light came in, and the door of the hut that had closed me disappeared, and many of me rushed in at the same time. I felt my strength regain a lot, and I scuffled with the man I didn't know. But she was much stronger than I was, and just as she was about to lock me up in that room again, another light, even more blind, came in, and she vanished......" Alyssa continued, "I don't know how long it took for me to wake up and see what Professor Frost was doing to you, and I realized that what I had seen before was not a dream......"

When Alan heard this, he understood why Alyssa's words and deeds were inconsistent, and it was the result of Alyssa's soul and Frost's soul vying for dominance in her body. And his light elemental magic seems to have some special effect, remembering what Professor Frost said before, Alan guessed that it should be his magic that liberated Alyssa's soul fragments who were locked in the soul sucking lamp, and those souls returned to Alyssa's body for the first time, driving out the soul of Professor Frost who had illegally invaded, and then there was the later scene.

"I don't quite know exactly what happened, and Professor Frost taught me a lot, but I ......," Alyssa said, lowering her head, a little hesitant, "I prefer to believe Alan...... No matter what happens, I'll be on Alan's side. ”

Allen's heart warmed when he heard this, and he thought for a moment, and then told Alyssa the whole story.

"In other words, is it Professor Frost's doing?" said Alyssa, who was startled herself.

"Yes...... In order to continue to live, she has been conducting forbidden experiments and looking for new containers for her soul. "She took a fancy to you, and then she approached you step by step, secretly carrying out her plan." ”

"No wonder I had been feeling sleepy...... "Alyssa suddenly realized, "I just remember being in Professor Fran's class that day, and then I couldn't remember anything...... When I woke up again, I found myself lying on a large rock, but my body was out of control...... Until then that light appeared......"

"And how are you feeling now?" Alan asked tentatively, "uh...... Do you remember Riel?"

"Of course I do. Alyssa said, and yawned, "It's just a little weird, I've been asleep for so long, and I still feel a little sleepy......"

Sure enough, some soul fragments were still missing......

Alan looked at the notebook in Alyssa's hand and asked, "What is this notebook?"

"Is this this?" said Alyssa, flipping it open, "it was on me when I regained consciousness, like Professor Frost's stuff......"

Allen's heart tightened, as if he saw hope, and hurriedly said: "Lend me a look! Maybe there will be ...... on it."

Alyssa handed him the note.

The notebook looks not too far away, and should have been brought in by Professor Frost when he entered the castle. Alan hurriedly flipped through it and found that it contained a large amount of ice elemental magic, as well as some spells classified as taboo by the Magic Management Association.

A few pages also contain information about the implementation of the entire project of "Soul Invasion" and her experience in experimenting with it all along. The whole process is tedious and complicated, and there are quite a few details that need to be paid attention to. The general meaning is this: first, to confirm a suitable container, its magical properties must be basically the same as that of the intruder, secondly, to use the soul-sucking lamp to drive out the original soul in the container, the process takes time according to the mental power of the original owner of the container, and finally, to use a special enchantment to take one's soul out of the old container, and then slowly guide it into the new container.

Souls that have been extracted from the Soulsucking Lamp have three destinations: wandering in the air, staying in the Soulsucking Lamp, or being sealed. Although the extracted soul will not be visible to the naked eye even if it is allowed to wander, since each person's body is inherently attractive to their soul before they die, the extracted soul will generally wander near its original body. Because these souls instinctively want to reclaim their bodies, they will briefly return to their bodies while the intruder is unconscious, such as when they are asleep, and become entangled with the souls that invade later. So if you want to avoid this kind of accident, the best thing to do is to seal it. This involves a spell called "Soul Shackles".

Alan turned the page when he saw this, because what he was looking for was not how to seal, but how to break it.

Sure enough, on the next page, there is such a mantra: The lonely soul removes the shackles for you, and although you are still lonely, you will not lose your freedom.

Alan looked at Alyssa, then led her to Mary and recited the incantation.

Mary had woken up. I saw it scream softly, although I didn't see anything coming out of its body, but seeing Alyssa suddenly tremble, Alan understood, and the last bit of soul fragment also returned to her body.

Alyssa opened her lips slightly, as if she wanted to say something, but she blushed and smacked her lips and closed them again, and after a while she walked over to Cynthia and sat down, pretending to be nonchalant, "Thank you." ”

Cynthia was stunned for a moment, glanced at her, held back a smile and said, "Don't get me wrong...... Well...... I just wanted to help Alan, and I knew he couldn't do it alone. ”

I saw that Alyssa's face was red and white, as if she wanted to be angry, but after a while, she held back: "We really can't get along." Then he sat aside.

It seems that Alyssa has remembered everything that happened before, and the two of them still don't seem to see each other......

Seeing that the atmosphere was a little awkward, Alan had to take the initiative to divert the topic: "Take a break and prepare to go back...... Well, it's not easy to walk a little later. ”

It was almost dark, and only a little light was left on the horizon to prove that the sun had not completely set.

After a brief discussion, it was decided that Alan would carry Cynthia, and the unconscious Rare and Frey would be carried by Alyssa using the levitation charm.

But just as they were about to leave, Will's voice rang out from behind them, "Mr. Patna?

Alan was stunned for a moment, looked towards the lake, and found Will leading a group of little gnomes over here.

Alan was a little excited: "Why are you here?"

"Well, if you want to hear the real reason, please promise me first, don't be angry......"

"Well, that......'s good," Alan wondered a little, "I'm not angry, you just say it." ”

"Actually, I knew you were here as soon as you left......" Will kept his hands behind his back and lowered his head, "I heard everything you said in the house at the time, but you were gone when I tried to go in to stop you from coming here......"

"Stop us?"

"Yes, because Will knows what a dangerous place it is......" Will said, "I saw in my father's memory, there were two devils here, and a lot of ice cubes that would eat people......"

"Ah......" Alan remembered when he heard this, old Seapheus must have been here, "no wonder he tried his best to dissuade me from meddling in these things......"

"But since you have to be close here, as soon as the ice melts in the school, Will rushes to help his friend. Will looked up, "But those devils and demons seem to have been dealt with by you?"

"Hmm...... Is school back to normal now?" Alan asked.

"Yes, the ice has all melted, and the barrier that covers the castle is gone. Will said.

"Then let's go back quickly!" This news made Alan can't help but be a little excited, "There are still two patients here who need a doctor." ”

"Okay, as you wish. Will said as he motioned for the little Seaphus to pick up Rare and Frey, "Please follow me." ”

Will said and led the way towards the cave.

"Where are you going?" Alan wondered.

"Now that the campus is full of students, we can't go back from the dungeon...... If someone learns that we've gone to the dungeon, it's going to be big trouble. "We're going to have to go the other way." ”

Alan had no choice but to hold Cynthia to follow.

But Cynthia suddenly remembered something, and looked back at the lake.

"What's wrong?" asked Allen.

"That book ......," Cynthia whispered.

"Ah......" Alan also remembered when Cynthia said this, and couldn't help but look back.

This time they were able to survive the crisis, and that strange magic book helped them a lot.

But when you think about it, it seems that after Professor Frost's soul was driven out of Alyssa's body, it seemed to be gone. Now the lake behind them was also calm, and nothing that would glow existed.

It's also strange to say that this book is also strange, when I picked it up, it was obviously the magic of the light elemental system, but on the way, it turned out to be the elemental system that Cynthia is good at...... It's incredible.

Is it the same book?

"Please follow, there's still a long way to go. Will urged.

Alyssa was also a little unhappy: "Let's go, I haven't eaten in a long time." ”

"Okay, here we go......" Alan had to retract his thoughts and keep up with Cynthia.

Will didn't go into the cave, but into another small hole next to the cave. This hole also leads straight into the ground.

No one asked, and after today's toss, everyone was exhausted, so they just followed Will forward. Alan just felt that the style of this dark passage was very familiar, a bit similar to the corridors that can be seen everywhere on campus. It wasn't until he was about to get to the exit that Alan came to the conclusion that Professor Frost might have asked Mr. Winslow to help build it so that she could get from the office to her "palace" and take care of her two "children". The one in the dungeon may have been built by the Stone family so that they and their property could be safely transferred if something happened.

This passage was more tortuous than the other, and it took them twice as long because Cynthia couldn't walk fast.

But when they came out, they were stunned...... In front of them was an office-like room.

"This is here?" Alan looked around, feeling as if he had been here.

"Professor Frost's office......" Alyssa recognized at a glance, after all, she had been in and out of the place for many days in a row.

Looking at the secret door behind the bookshelf, Alan understood that Professor Frost did not mysteriously disappear that day, but entered this secret door.

But when Alan saw the painting hanging on the wall, he was stunned - there was only one frame left, and the strange-looking eye was gone.

"What's wrong?" asked Alyssa and Cynthia at the same time.

Alan pointed to the frame, "That picture...... It's weird......"

"It's weird. Cynthia glanced up and said, "It's good to draw whatever you want." ”

"No, that's not the case...... It's a little different from what I've seen before......" Alan shook his head, then asked Alyssa, "Did you see anything on it when you came here before?" uh...... For example, one eye ......"

But Alyssa shook her head: "Every time I come in, I feel very sleepy, in a trance, and I have never paid attention to other places......"

"Okay......" Alan shrugged, looked at it again, and walked out the door with them.

The campus was full of standing water, and it was also crowded with students who came out to join in the fun.

They first sent Riel and Frey to Professor Watson, who was busy caring for the frostbitten and unconscious students when he was shocked to see them come in like this. Professor Watson first settled the two unconscious patients, and then briefly examined them, and found that the condition was not serious, and they would wake up after a few days of rest, so Alan reassured Professor Watson about the whole thing.

Later, to celebrate Alyssa's safety, Alan and her have a sumptuous dinner. Although she didn't have Riel with her this time, Alyssa seemed to be happier than before.

Back in his room, lying in bed, a sense of relief welled up in Alan's heart, and he could finally get a good rest.

Although the matter was over, Alan couldn't sleep after tossing and turning, and there were still many questions that kept circling in his mind: what was the relationship between Frey and Doug, how could he have the key to the dungeon? And Mr. Winslow's "teacher", what secret did he and Professor Frost have to hide? What was there in that forbidden valley? How many magic books were there that mysteriously appeared and disappeared suddenly, and were regarded as ominous, but helped them a lot? And the "he" that Professor Frost says at the end refers to Arne Burresto, who committed a heinous crime 14 years ago?

It's all a mystery. But after thinking about it, Alan could now be sure that Professor Frost's last horrible laugh told him that she wasn't talking about it, as if someone was secretly planning something, and that the "he" she was talking about might really be coming......
