"Uh-he-he-he......"

Sakura smiled embarrassedly, although the clothes that Chiyo brought her were indeed cute, but she was ashamed to wear them every time.

"Okay, let's go, the seal will end early."

Xia Yu looked at Sakura and Chiyo, who still wanted to continue chatting, and ended the conversation directly and ruthlessly.

"That...... Do you know where the real identity of the Kuluo card is? ”

Hearing Xia Yu's words, Sakura asked curiously, although Xia Yu said that it was the ghost of the Kuluo card, and she did feel a little abnormal, but she couldn't determine the specific location.

"Uh...... I don't know. ”

()

"Don't know? You don't know, Mr. Xia? So where do we investigate? ”

Sakura was a little dumbfounded, and couldn't help frowning and said, "I brought Xiao Ke if I knew it, and Xiao Ke could sense the magic of the Kuluo card." ”

"Don't worry, I don't know, but isn't there still it?" Xia Yu suddenly shook the wand in his hand, and then chanted with a serious expression.

"The heart of the south, the pupils of the north, the fingertips of the west, and the toes of the east, gather with the wind, drive away the rain and disperse!"

"Show me the way!"

Putting aside the useless chanting in front of him, after the last spell sounded, the wand in Xia Yu's hand floated slowly, and the tip of the wand also pointed in one direction.

"Okay, now I know."

"Oooh! It's amazing! ”

Sakura's eyes were shining as she looked at the wand floating in the air, and she couldn't help but feel envious, why didn't her pink wand have so many functions!

It's still Xia's magic wand, it's not only low-key, but you don't need to lift the seal, you can use magic when you take it out, and you can use it to guide you when you get lost, it's really easy to use!

Next, because of the magic wand to guide the way, the few people didn't need to investigate everywhere, and after walking around the interior of the aquarium, they soon came to the core area.

Luckily, they were invisible, so the patrolling security guards couldn't spot them, allowing them to easily infiltrate the aquarium's core reservoir.

And there is very little surveillance in this era, of course, because they are already invisible, so even if there is surveillance, they are not afraid.

"Well, I feel it."

Suddenly, Sakura stopped moving on, and she snapped into one of the pools.

The reservoir of the aquarium has more than a dozen large pools, each of which is connected to an aquarium below, and I don't know what the aquarium thinks, these pools are not sealed, but are so wide open.

"There's a strong magic reaction in that pool, and the Kurot cards must be hidden in there!"

Sakura swore that she might have been skeptical before, but now she was sure that there was definitely a Kuro card in this place.

Although she is not familiar with it now, she is the only Kuro magician in this world after all, and when she gets close to the Kuro card, she can naturally sense the magic of the Kuro card.

"It seems that Xia's guiding magic is really powerful."

Zhishi held the camera and shot Xia Yu, and recorded Xia Yu's posture into the camera.

"I've found it, but how do I seal it?"

The three of them walked to the pool together, and Sakura also looked at Natsuyu and asked.

"Directly lead out the seal."

Xia Yu grinned, under Sakura's curious gaze, Xia Yu stood on the edge of the pool and yelled at the pool: "Hey, you have the ability to bully penguins, you have the ability to come out!" Don't hide inside and keep quiet, I know you're in there! ”

As soon as these words came out, a whirlpool suddenly rolled up in the originally calm pool, and then a column of water suddenly gushed out of the pool.

The next moment, the water column formed a slightly blurred blue figure, and the blue water flowed around the figure, and even the air was a little moist.

The water card that appeared looked at Xia Yu and the others condescendingly, and suddenly opened his mouth and roared fiercely, and pounced directly on the three people below.

"Get out of the way!"

Seeing that the water card did not speak of martial arts and attacked directly, Xia Yu hurriedly dodged and retreated, and at the same time pointed his wand at the water card.

"Shadowless!"

The moment the tip of the wand lit up, the originally menacing water card was instantly torn apart and turned into a splash of water.

This spell can tear the target and cause it to bleed, but the water card is not a real living entity, so the splash of water merges back into one and becomes an unscathed water card.

But this was enough for Xia Yu and the others to stay away from the water card, but the water card obviously did not let go of their thoughts, and after reconverging, the water card swept the water waves towards them again.

It's just that looking at the thickness of the rushing water, it is obvious that Sakura is the main target of the water card.

"Ahhh Why are you coming at me? ”

Sakura cried as she drew her wand and slammed it on the flying card.

"Fly!"

In an instant, the wings on both ends of the wand quickly grew larger, carrying Sakura in the air, dodging the incoming currents.

On the other side, because the water flow from Xia Yu and Zhishi's side was very small, Xia Yu just casually expelled the enemy and stopped the attack of the water brand.

Expelling an enemy summons a magical barrier where the caster is trying to protect, which cannot be broken by normal magic.

Of course, it was mainly because the water card was not on their side, but kept chasing Sakura to attack.

"Oh, Sakura is going to be caught up, what should we do?"

Zhishi looked at Sakura, who was being chased, and was very anxious, but she didn't know magic, and even if she wanted to help, she couldn't do it, so she could only ask Xia Yu anxiously.

"Don't worry, I already thought about it before I came, since this Kulo card is water, then I can't just freeze it."

"Freezing? Water? ”

Zhishi was stunned for a moment, and quickly understood Xia Yu's thoughts: "Could it be that the ice storage is used to freeze the water?" But the freezer is under the aquarium, and we don't have the keys yet. ”

Hearing this, Xia Yu glanced at Zhishi strangely, and waved his wand in his hand: "Why do you always forget that I actually know magic, look at me!" ”

Looking at the water flowing closely behind Sakura, Xia Yu's wand pointed: "Freeze quickly!" ”

A light like the brilliance of welding flashed from the tip of Xia Yu's wand, and then a stream of cold air hit the stream of water.

With a click, the continuous catapult torrent was instantly frozen, and the cold air slowly drifted out of it, bringing a little ice crystal to the already humid air.

"Successful ......"

Before Xia Yu could finish speaking, the frozen water suddenly clicked and cracked, and then a blue figure like a mermaid appeared from the water and looked at Xia Yu angrily.

Xia Yu: "......"

Water card: (▼ヘ▼#)

This water card didn't take Sakura as a target anymore, and shot directly at Xia Yu.

"Why didn't you freeze? It's not scientific! ”

Seeing the torrent like a high-pressure water gun shooting towards him, Xia Yu hurriedly spread his wings and fled like Sakura at the beginning.

The water flow manipulated by the water sign was extremely sharp, and it left a deep mark just by scraping it on the ground.

If you are attacked, you will definitely leave a deep injury on your body, and you may even be life-threatening.

"Damn, we're elementary school students, you actually killed you, how did your master teach you!"

Xia Yu fled while condemning the water card chasing behind him, but the water card not only did not stop, but sped up.

"Tsk! Asunder! ”

With a snap, the mermaid-shaped water card exploded directly again, but those streams turned into water arrows instead, shooting straight at Xia Yu!

"Wind!"

At this moment, Sakura manipulated the wind card into a tornado, engulfing all those water arrows, and also including the water card.

The wind and water in the four elements fought fiercely in an instant, but because they were both invisible elements, no one could help anyone, and they could only fight for control of the tornado at the same time, which also made the tornado become a wind tornado for a while and a waterspout for a while.

"Student Xia, are you okay?"

Sakura flew to Xia Yu and asked with concern, Xia Yu shook his head and told Sakura what he had just thought.

If you want to trap the water completely, you can only choose to freeze the water flow, or directly evaporate the water flow into water vapor, but between water vapor and ice cubes, the latter is obviously easier.

After a brief discussion with Sakura, the two immediately decided to use the ice vault to freeze the water, and Xia Yu went to the ice vault to open the door in advance, and then Sakura brought in the water.

Because Xia Yu can also use the spell of expelling Muggles to expel ordinary people on the way, so he is not afraid that someone will be affected by this, and they are not afraid of being discovered by others when they seal the Kuluo card.

The plan was good, but the two soon discovered an awkward problem, which was that neither of them knew the way to the freezer.

Even if Natsuyu can find the ice vault through the way-pointing magic, if Sakura doesn't know the way, she won't be able to guide the water through on her own.

Unless two people act together, but then Xia Yu can't step on the point in advance, and if he meets ordinary people such as security guards halfway, it will be even more troublesome.

Just when the plan was at an impasse, Chiyo suddenly walked over.

"Don't worry, I've just found the map nearby, the freezer is on the negative floor of the aquarium, I know the way."

After finishing speaking, Zhishi looked at Xia Yu: "Classmate Xia, you should go and step on it in advance, and I will show the way for Sakura, and ......"

While speaking, Chiyo looked at Sakura and smiled sweetly, "Sakura-chan, you will definitely protect me, right?" ”

Hearing this, Sakura was a little moved, and her expression immediately became serious: "That's right! You'll be sure to protect you, Zhishi! ”

"That's good!" Xia Yu nodded, flapped his wings and took off: "The battle begins, you can come over in a minute!" ”

After that, Xia Yudang said "show me the way" and flew towards the ice warehouse on the negative floor.

Seeing Xia Yu leaving, Sakura's side was not to be outdone, and after letting Zhiyo also sit on the wand, he immediately guided the wind card to control the flow of water.

After a minute had passed, Sakura hurriedly followed Chiyo's direction, attracting the current of water to fly towards the negative layer.

I don't know if it's because the water card has been teased for so long, and he has been carried away by anger, but he didn't suspect fraud at all, and attacked Sakura directly.

Although leaving the pool, the power of the water card has not diminished at all, and every time the water whip hits the wall, it causes a loud noise.

Sakura, who was using the bait in front of her, could almost feel the entire aquarium tremble, but when she flew some distance in fear, she still didn't see anyone.

It seems that such a large movement cannot make the security guards here wonder at all, as if the patrolling security guards have already left work, even if it is still daytime.

After realizing this, Sakura breathed a sigh of relief, and silently gave Xia Yu a thumbs up in her heart, so that she didn't have to worry about being discovered.

If Xia Yu was here, he would definitely talk about it with his head held high, but he had used the three spells of "all protection", "muggle shielding", and "closing earbuds and listening".

Even if this place is demolished, no one will notice, and no one will notice the problem until the spell fails.

Sakura, who had no scruples, sped up again, and finally, after passing through the last staircase, she saw Natsu Yu standing at the top of the stairs beckoning, and below the staircase was the ice storage door.

Once at the location, Sakura and Chiyo leaped down and landed on the ground from mid-air, the wings on both sides of the wand rapidly shrinking and turning back into small wings on both sides of the bird's head.

Boom!!

At this time, the water card had also caught up, and the rumbling sound of the water echoed around, as if it was about to completely crush the place.

Seeing that he seemed to have cornered these imps, the water card opened his jagged mouth and let out a silent laugh.

But soon, the wind sign came up again, and the wind mixed with the vast flow of water, and the two became entangled again.

"Student Xia, the water flow has been controlled by Sister Feng, open the ice store quickly!"

"Good!"

Seeing the wind sweeping the water straight towards the ice vault gate, Xia Yu hurriedly pointed his wand at the ice vault gate.

"Alaho Cave Open!"

Alaho Cave Open, a spell that opens locked and unprotected doors and windows, is easier than picking locks.

The door of the ice vault immediately opened, and then the intertwined wind and water carried the violent force into it, and entered the ice vault filled with cold air together.

After entering the ice store, the gentle wind also took advantage of the situation to bring the door of the ice store, completely trapping the water card inside.

It wasn't until the cold air made Shui Pai feel stiff that Shui Pai realized that she had been tricked, and if she didn't escape from this environment, she would be frozen.

However, as soon as Shui Pai wanted to gather all his strength to knock open the door of the ice warehouse, a voice suddenly sounded outside the ice warehouse.

"Freeze quickly!"

Immediately after that, in the wide eyes of the water brand, the door of the ice storage that was originally unlocked was directly frozen, and even the cracks in the door were ice ballast.

Water card: It's over, it's cold directly.

Next, under the sweep of the wind brand, the original flowing wind brought a cold air, and sometimes the gentle wind can be as cold as winter.

In an instant, a small blizzard was staged in the freezer, still mixed with hail.

In this extremely cold environment, the water card has felt its body become more and more stiff, and if it does not escape from this place, it will definitely be completely frozen.

However, no matter how much it tries to break through the blockade of the winds, it is only doing useless work.

In the end, this mermaid-like water sign was frozen into an ice sculpture with teeth and claws, and on the face of the ice sculpture, you can still see a bit of lifelike anger.
