After chanting the incantation, Brian took a deep breath and dived into the water, leaving only a string of bubbles on the surface.

Seeing this, Eren also began to try to chant incantations. Since it was the first time to take this kind of outdoor class, and it was in the water, in order to avoid choking on the water due to the lack of success in casting spells, Alan was very cautious and dived down little by little.

When he opened his eyes, the water was a little cloudy and yellowish, and a smell stronger than the shore filled his nostrils. However, after holding his breath and feeling it, Alan found that the magic seemed to be working, because although he couldn't breathe, he didn't feel stuffy at all, and it seemed that there was still a stream of air circulating slowly in his lungs, constantly producing exhaust gas, which made him want to vomit and turn into bubbles. It's just that this rhythm of exhaling and not inhaling makes him very uncomfortable.

Brian didn't stay where he was, but swam a little towards the middle of the lake, and when he saw Alan sneaking in, he quickly swam over to check on the situation. Unable to speak in the water, he only nodded after observing Alan's state for a while, and then motioned for Eren to try to move like him, or walk along the lake first.

Although Alan grew up by the quiet river, he has never learned to swim, so he can only step on the bottom of the lake. But after walking two steps, he felt that his oxygen consumption had suddenly more than doubled, and he felt a little dizzy, so he had to quickly stop and adjust the rate of consumption of mana. After a few adjustments, he was finally able to breathe smoothly while walking in the water. And he found that this magic not only seemed to allow him to breathe in the water, but the water did not cause so much resistance to his movements, and it was not as difficult as he imagined.

Brian was clearly more skilled, swimming as fast as a fish, and in the blink of an eye there was only a dark shadow.

There were no fish or algae in the lake, and it looked as bald as the mountain, except for the students in the distance, and there was not even a shadow of any living creature except for the students in the distance.

The water flowed, and Alan followed the direction of the current, and soon came to the vicinity of the outlet. He stopped, trying to look out along the fence to see what this side of the hill looked like.

The outlet is almost two people wide and more than one person deep, and it looks like a "V" shaped crack when viewed from underwater. Since he couldn't see the outside scene at all in the water, Alan had to float up. The water is fast, but it's a good thing it's there, otherwise some careless person might be washed out of the place without paying attention.

Alan could barely see at the foot of the mountain a small plain, and on the other side of the plain were several small meandering rivers, one of which was formed by the water flowing from here. I remembered that I had heard from the senior students that Crescent Lake was formed by the injection of the Letnness River, and that Crescent Lake was also a living lake, so Allen guessed that several other small rivers might have flowed out of Crescent Lake, and some might even be tributaries of the Letnness River. This plain is formed by the sediment of these rivers coming together here.

Perhaps because the soil at the foot of the mountain is more fertile, the plains are very densely forested.

After staying in the library for a long time, he could occasionally see such a beautiful scenery, and Alan couldn't help but feel refreshed.

But just as he was intoxicated by the enchanting scenery, he suddenly felt as if the speed of the water had increased inexplicably. Alan looked back and saw that the surface of the lake was calm as usual, but the water underneath was unexpectedly flowing faster and faster, and even began to hit the fence non-stop. And this fence is obviously only temporarily inserted here, and there are still signs of loosening under the constant impact of this current!

"What's going on?" Alan panicked and quickly called Brien's name for help, but when he looked back, he found that there was not even a figure on the water nearby.

At the same time, the impact of the water is getting stronger and stronger, so that Alan can only hold on to the fence and be completely immobile.

The rest of the lake was still as calm as ever, except for him, and Brian, who had been assigned by Frey to guide him alone, suddenly disappeared without a trace...... Remembering that the person who brought him here was also Brian, Allen's heart couldn't help but feel a sense of foreboding—he seemed to have fallen into some trap......

Thinking of this, Alan dived back into the water under the pressure of the current, taking advantage of the time when the current stopped, carefully observing everything at the bottom of the lake.

Sure enough, in the middle of the lake, not far from him, a small black shadow was waving his wand vigorously, and the frequency of the current was the same as the rate at which his wand was swinging. And this strong figure......

"It's really him!" Alan was shocked, struggling to get as close to the shore as possible, but the pressure of the current was too great, and he could only hold on to the fence to ensure that he would not be swept away by the current, and then hit the rocks on the shore.

"What to do, what to do, what to do?" Alan was so anxious that his scalp was numb, and at the same time, he was hit by this strong current, and choked on his saliva, unable to think of any countermeasures at all, "If this falls from here......" Alan closed his eyes in fright, not daring to think further.

This is the top of the mountain, and if you fall from this height, you will definitely die.

Just when he was about to panic to the extreme, he suddenly felt the fence in his hand loosen, and then the sound of running water in his ears instantly became much quieter, and his whole body flew out with him - what he feared most happened that the fence was uprooted by this strong current......

Alan only felt that his whole body suddenly became light, broke free from the water, and then began to fall rapidly!

The panic suddenly disappeared, because he didn't dare to open his eyes for nearly ten seconds, and his brain went blank, or there was only one thought: "Will I fall to my death......

But when he finally mustered up the courage to open his eyes and saw that there was still some distance from the ground, the instinct for survival made him force himself to calm down, and his brain began to work wildly, thinking of all possible ways to save his life.

"It'......s impossible to control your body with a levitation charm? Withstanding this impact with a barrier barrier doesn't seem realistic...... Or use a softening charm to loosen the dirt at the moment when he is about to fall to the ground?, but if he doesn't get the timing right, he may still be crushed......" Many ideas came to his mind one after another, and then they were rejected one after another. None of the magic he knew could help him.

"The forest is lush down here, maybe you won't fall to your death directly......" At this time, Alan saw the situation below, not only a little lucky, but after thinking about it again, he couldn't help but break out in a cold sweat on his forehead: "But serious injuries are unavoidable, if you are unlucky, some branches grow vertically upwards......"

Thinking of this, Alan couldn't help but close his eyes again, and even there was a faint pain in his abdomen, as if his body had been pierced by some sharp branches......

Seeing that he was getting closer and closer to the ground, there was not much time left for him to think.

"Leave it to fate...... Alan thought.

But at this moment, a faint tingling pain suddenly came from his right wrist.

"Ahh

"Just shout my name in your heart when you really need my help. A voice rang in Alan's ear.

I don't know how she'll help herself, but at the moment, it seems that this is the only way to do miracles. Thinking of this, Alan couldn't help but exert himself and shouted loudly in his heart: "Karin!"

A sharp pain came from Alan's right wrist, as if it was burning with flames, as if a piece of flesh had been cut off by a knife, but he looked at it painfully and found that it was just the mark glistening.

"Yo, no wonder they called me out to help, it looks like I'm really desperate. A slightly familiar voice came from behind Allen.

Then Alan felt as if his body had suddenly become lighter, and the speed of his fall was gradually slowing down, and finally he stopped dozens of centimeters above the canopy, and at the same time slowly regained his balance.

Alan looked back and saw Karin standing behind him to the left, a hand gently touching his shoulder.

"Don't be stunned, let's land quickly. Karin urged, "Unlike your magical power, our spiritual power does not accumulate over time, and a little consumption will result in a little less. ”

"Uh, uh-huh!" Alan nodded quickly and slowly landed with Karin.

Strange to say, it was the first time that he had flown in the sky without relying on Arthur, but he felt as if he had long been used to this, and he controlled his body as he pleased.

Through the woods, Karin landed with Eren on the bank of the nearest river.

"Thank you. Alan said with a long sigh of relief.

"What's the matter, how are you in heaven?" Karin asked, looking at Allen, "and...... No clothes?"

Alan was a little embarrassed, and he didn't know how to explain it for a while, so he lowered his head and said, "Uh...... That's a long story......"

However, after staring at him for a moment, Karin suddenly said, "Oh, human intentions are really as sinister as ever...... This one is named Frey Boy. ”

Alan was stunned for a moment, and then realized that Karin had seen the guess in his heart.

"Uh...... It's just speculation......" Alan hesitated for a moment, "maybe it really has nothing to do with him......"

"Should I say you're kind or naïve?" Karin chuckled and said, "You've made you like this, and you're still trying to exonerate him?"

"Uh......" Alan was completely speechless. Because even he himself doesn't know why, this mood is very contradictory, on the one hand, all the clues point to Frey, but he doesn't want to see that it is really him.

"But he seems to have expected you to call me out...... then Karin suddenly stared at a bush not far away, "and this jealousy...... I can't look any further, it's time for me to go. ”

"What?" Alan didn't understand, and wanted to ask something more, but with another tingling pain in his wrist, he just blinked, and Karin was gone.

Alan rubbed his wrist and found that there were no signs of injury, so he was relieved.

But before his tense nerves could be relaxed, he heard a rustling sound coming from the bushes behind him, and he couldn't help but shiver again.

At the same time, a familiar voice sounded: "Huh...... Sure enough, that mark ......"

Alan jerked his head back.

"It's an elf. ”
