After Cynthia finished speaking, she walked straight down the mountain, and the three of them had to hurry to follow.

Although the slopes are covered with snow-covered meadows and the Crescent Lake can be seen in full view, it should be a good place for an outing in spring, but there are few signs of human activity on this mountain.

Looking closer, Alan felt more and more that something was wrong with the mountain.

But before he could speak, Riel had already said first: "This place is so strange......"

Alan looked at him a little unexpectedly and said, "What, you found out too?"

Riel looked left and right and asked Allen, "It's a mountain, and there isn't even a tree?"

"Yes......" Alan smiled, only to realize that Riel was not the same as his focus, but this was also one of the anomalies, so he nodded: "Compared to the mountain of Beya, the difference is a bit big." ”

"Is it because it doesn't rain so often? It seems like we've only had one rain since we got here. ”

"Probably...... Who knows. Alan shrugged, and then said, "More than that, I want to know why the Stone family dug this secret passage here, and after repairing it, they hardly need it." ”

"How do you know it was dug by the Stone family?" "Rare was stunned, "and you know that this secret passage is barely used?"

"Don't you think it's very similar, the structure of this secret passage is similar to that of the twin spires?" Alan smiled, "Since the twin spires are left over from the Starr family, then there is no reason why this secret passage was dug by someone else." ”

"Hmm...... Possibly......" Riel nodded.

"And you look at the ground here. Alan pointed to their feet, where his foot had just made a black footprint on a small patch of snow, and then slowly revealed the grass underneath, "What is this?"

Rare didn't know what he was selling, so he squatted down and took a closer look, and pulled the snow away with his hands, revealing the green grass below: "It's just ordinary grass...... Tranquility by the river is not everywhere. ”

"Yes, the whole mountain is meadow......" Alan gave him a meaningful look, "but there is not even a road." ”

Riel was stunned when he heard this.

Oh, yes...... It stands to reason that there is such a secret secret door in the middle of the mountain, and there should be a road nearby, but through the snow that is about to melt, they can't even find the shadow of the road.

"That's why I've concluded that this secret passage has hardly ever been used...... At least not in recent years. Seeing that he did not speak, Alan continued.

"That's weird......" Riel muttered. A mountain without even a tree, a secret door for some unknown reason, and the inexplicable inaccessibility of this place have completely confused Riel.

By this time they had reached the foot of the mountain.

The Crescent Lake and the foot of the mountain are almost connected, and the two are only a few steps apart. The shore is also not wooded like the one around the Blue Lagoon, but is bare, still with only grass.

However, it is still quite shocking to see the Crescent Lake up close, especially as it is now, the entire lake surface is frozen into a whole, there is nothing superfluous on the surface of the lake, and it is as smooth as a mirror.

"The shape of this lake is really interesting...... "Riel said, looking around for a moment, "it's like the moon in the sky falling and smashing into such a shape, right between the two mountains." ”

"I heard that this lake is not naturally formed, it is excavated by hand. Frey simply explained and crouched down.

He bent down and found that his hand was just enough to touch the lake. However, thinking of the strange ice cubes in the school, he did not dare to touch it rashly, but first found a small stone on the shore and threw it down, and found that there was no sign of freezing, so he cautiously stretched out his hand to the lake.

But by this time, Rare's voice was already ringing on the surface of the lake: "Hey, come down and take a look! It seems that there is only this thin layer, and the water below is alive!"

Several people feel angry and funny, and Riel's reckless personality will cause him some trouble sooner or later. But seeing that he was jumping around on the ice without doing anything at all, they were relieved. Frey only opened his mouth, gave him a helpless look, and said no more.

The three of them also come to the ice to see Riel's new discoveries. However, this look is not tight, and a layer of cold sweat can't help but break out on the foreheads of several people...... This layer of ice is almost as thick as a human hair!

Alan couldn't help but feel his legs go limp, as if the ice under his feet could shatter at any moment, which made him take two steps back, wanting to hurry back to shore. Looking at Riel again, he didn't seem to notice anything like this, and was still bouncing around on the ice. But the strange thing is that no matter how hard Riel jumps, this layer of ice is as hard as stone, not to mention broken, there is not even a crack at all.

"Look, there's fish swimming down there!" Riel stared at the bottom of the ice with excitement, almost lying on the ice, "and there are so many aquatic plants!"

However, Frey and Cynthia ignored him and walked straight to the opposite mountain.

"Let's go, we're not here to travel. Alan also urged. Seeing that the ice was hard enough to support their weight, he quickened his pace and followed the two men in front of him.

The location of this mountain is also quite interesting, if the lake is not crescent-shaped but a full moon, then the hill opposite is in the middle of this full moon.

And because the Crescent Moon Lake is not small, several people walked all the way east for nearly half an hour before finally coming to the foot of this mountain.

However, unlike the back mountain, the vegetation on this mountain is more sparse, and there is not even grass. The whole mountain was rocky and extremely difficult to climb as far as the eye could see, and from the time they came ashore, they found a rather strange thing - only the perimeter of the mountain was snowing, not even a single snowflake on the nearby Crescent Lake.

Alan looked up at the sky and saw that only the clouds above this mountain were thicker and darker than the rest of the world.

It was as if the dark cloud was enclosed by an invisible shackle, and it only lingered above the mountain, resolutely not moving a little else.

"This cloud is weird...... "Riel stared at the sky in amazement.

"I have a sense of foreboding...... Cynthia, who had been relatively silent at this time, suddenly opened her mouth, and Alan looked at her and found that her face was quite ugly, and even showed some imperceptible nervousness.

"What's wrong?" asked Allen.

"I don't know who is using this magic, but I can feel the magic in this cloud......" Cynthia reached for a few snowflakes and found that they showed no signs of melting after touching her skin, "and these snowflakes ......"

At this time, Alan also felt that there seemed to be something wrong with these snowflakes, unlike the ones they had seen in the castle before, these snowflakes were not the kind of goose feather snow, but they were falling one by one, but they showed no signs of melting after falling on their bodies. And what's even more bizarre is that as he fights in the snow for more and more, he begins to feel heavier and heavier, as if there is an invisible force oppressing him.

"Oh no! there's something wrong with this snow!" Frey shouted as he shook the snow off his body, and ran towards a dark spot at the foot of the mountain.

But just then, it seems that the snow suddenly starts to fall heavily!

The snowflakes fell on them even more violently...... No, the snowflakes seemed to be flying towards them consciously, and with a strong wind, even the snowflakes that had already fallen on the ground began to wrap around them!

"Not good!" several people were taken aback, and struggled to keep up with Frey's figure.

Alan couldn't see what was there, only a dark shadow on the rock wall. But now he was in a panic, and he tried to follow Frey's footsteps as he pulled the snowflakes that were frantically sticking to him.

Seeing this, Cynthia directly took out her wand and used wind elemental magic to form a high-speed rotating air flow around her body, separating all these snowflakes.

"What are you doing in a daze, come with me!" Seeing that those people didn't react,

Alan was terrified for a while, and suddenly felt something moving at his feet, and when he looked down, it turned out to be a black cat, circling around him, and scratching his clothes from time to time, and it seemed that the cat was very interested in Allen, and Allen squatted down, and as a result, it kept rubbing Allen's body with its head, and Alan just wanted to touch its head, but suddenly Professor Frost's voice sounded, "Mary, come to Mommy's" As a result, the cat suddenly became a little strange, and looked back at Professor Frost in a daze, and then walked over slowly

Professor Frost asked Alan what he was trying to do, and he just replied, "She's probably too tired lately, and her body can't bear such a heavy load after continuous make-up classes, and it will be fine to rest for a few days."

However, as Professor Frost said, Alyssa's condition did not improve, but she fell into a coma, and Alan decided to go and ask Professor Frost again, only to be told that the professor had taken a leave of absence and left the school

Approaching the middle of the month, they were discussing how to spend these two days, but suddenly the weather changed suddenly, and it was snowing heavily in the middle of October, and Alan and Riel had never seen snow, so they were very excited, but then suddenly the sun was shining again, and a strong wind blew, and the whole school was frozen overnight, and Alan went to the school hospital to visit Alyssa, but found that Alyssa, who was supposed to be lying in the hospital bed, suddenly disappeared, at first I thought she had regained consciousness, but the search was fruitless

At this time, the news came, all the communication lights in the professor's office had been destroyed, and a window was finally broken, and the communication bird released by Professor Stubone was shot down by the ice as soon as it flew out, and everyone realized that the situation was wrong, and they encountered an unprecedented crisis
