The bodies of the three of them leaned into a small area of space as much as possible, which could reduce the defensive dead angle as much as possible, but this kind of small-area positional defense is Karina's forte.

The magic power of the ice attribute was mobilized by Karina to the greatest extent at this moment, and her magic power caused the temperature of the surrounding space to plummet, and in just one breath, the surrounding temperature had reached more than ten degrees below zero, and you must know that the surrounding temperature was close to eighty degrees before that.

Such a drastic change in temperature made the movements of those monsters obviously sluggish, and even their bodies began to appear ice floe, which was the ice condensed by the combination of Karina's control magic and the surrounding water vapor, which was almost pervasive, and Karina's control of the magic power was to let these ice seep into the joints of these monsters, thus further slowing down their movements.

And these monsters are close to the middle range, it is time for Han Kun to make a move, the bright red magic line is under Han Kun's wielding, constantly wandering around the three of them, once the magic line touches these monsters, what awaits them is that their bodies are cut into pieces, Karina's magic also reduces Han Kun's pressure a lot, and even he alone can defend all the attacks from all directions.

Ao Bai's task is very simple, that is, to slaughter the fish that Han Kun left behind, although it is no problem to rely on Han Kun alone, but there are still occasional monsters with mutilated bodies rushing towards the three of them, and these monsters are all punches from Ao Bai without hesitation. With the extremely tacit cooperation of these three people, they forced all the surrounding monsters to turn into powder on the way to attack, although it seemed that even if they were destroyed, there was still the possibility of rebirth, but Karina used ice to completely seal the movement of those fragments, directly cutting off the possibility of rebirth.

The battle only lasted for a short time, and by the time Han Kun's mana line dissipated, the three of them were already covered with crystalline fragments, stuck to the ground by Karina's ice, unable to move.

"It seems that these monsters are indeed not very resistant to magic."

"Well, they don't even use magic."

Han Kun replied to Karina as he squatted down and picked up a small piece of debris on the ground with his hand.

This is a pale red crystal fragment without any magic fluctuations, if these monsters were not killed by Han Kun himself, Han Kun would not even think that this pale red crystal would be the remains of a monster, the fragment that Han Kun picked up was only half the size of a palm, but the mass was unexpectedly heavy, the density of this crystal was close to the lead on the earth in comparison, but when Han Kun picked it up, this fragment was no different from a dead thing, and it was not as attracted to each other before the fragments as seen before, and finally returned to its original state.

"Let's go, there's no need to stay here, my magic is estimated to last for about ten minutes, and this time is enough for us to leave." Karina urged, she didn't want to waste more time here.

"Well, let's move on."

Putting the fragment into the space stone, Han Kun jumped up from the ground, and the three of them entered the new tunnel again.

As before, the color of the walls was changing, this time from red to orange, and it wasn't long before the tunnel ahead was completely yellow. This is the same as Han Kun guessed.

An open space appeared in front of them again, which also made the three of them vigilant again, but when Han Kun spied forward, there were no monsters in this independent space, which made Han Kun breathe a sigh of relief.

"It looks like there's no monster ahead. And the exit is also on the opposite wall, we just need to fly over it. ”

Ao Bai and Kailina both nodded, for the sake of safety, it was still like before, Ao Bai took the lead, let Ao Bai go alone to test the situation first, and if there was danger, the two of them could also take action in time.

This time, Ao Bai also chose to jump directly to the other side of the tunnel, without any monster interference, according to Ao Bai's calculations, such a jump should be able to easily cross.

But the fact slapped Ao Bai again, and before he reached half the distance, his body was like suddenly hitting a wall in the air, and the sudden collision made Ao Bai's body orbit change greatly, and he was almost parabolic at the moment, but at this moment he fell straight to the ground.

"Tsk, is there an invisible wall ahead?"

Ao Bai spat on the ground. Due to his high speed in the air, he also had no room to use his magic to detect, and the unbridled blow even caused his face to hit the wall.

Unexpectedly, just the moment the soles of his feet landed, the brilliant yellow crystals in the entire space seemed to be activated in an instant, and began to emit brilliant golden light towards the surroundings, and at the same time, the space under Ao Bai's feet began to change!

"I know it's not that easy, Karina, let's go!"

"Don't come here!!"

Ao Bai's loud roar forcibly stopped Han Kun roaring in place. Because he missed the first time to enter, even the tunnel mouth in front of him was completely sealed by the crystals that suddenly spread, and Ao Bai was completely isolated in the space in front of him.

The movement only lasted for a few breaths, and when everything around him was quiet, Ao Bai's voice came from the wall in front of him:

"I'm fine. It's just that it's all blocked off by a golden thing. ”

"Can you try to break it with brute force?"

"No, I've tried. Whether it was the wall of air in front of me, or these crystals, I didn't even change anything with one punch. ”

"Don't worry, Kailina and I will try to break it from the outside!"

Thankfully, these crystals are not isolated from the transmission of sound. Although Ao Bai was trapped in it, the sound could also reassure the two people who stayed outside. schoolbag

Han Kun no longer hesitated, his right hand swung violently at the crystal in front of him, and five magic lines in a row roared towards the mouth of the sealed tunnel, but even Han Kun's magic power line actually collapsed after hitting the crystal, and not even a trace was left.

"How can it be so hard?"

Han Kun frowned, the originally invincible magic line didn't even leave a trace this time, this was really too strange.

"Let me do it, since it doesn't work, then I'll try something else."

Karina stepped forward and held out a hand that was attached to the brilliant golden crystals. Unexpectedly, even Karina's magic power could not penetrate into these crystals, these crystals were like natural magical insulators, and the magic could only adhere to their surface at most, forming a thin film. But being able to do this is enough for Karina.

The magic of the ice attribute caused the temperature of these crystals to drop to a fairly low level in a short period of time. Karina even used her body to make direct contact this time, and the effect of mana cooling was even worse than when she dealt with those monsters before.

When the temperature of the crystal had been reduced to a point where it could not be cooled down much if it continued to increase the magic power, Kailina's magic power suddenly changed qualitatively, and the magic power of the ice attribute was ignited at this moment, and the original pale blue magic power changed to orange and red at this moment, which is exactly Karina's forte-attribute transformation of magic power.

The crystal that had been kept at a very low level was heated up sharply at this moment, and the magic power of these two attributes was exactly two extremes, and under such a cold and hot transition, fine cracks suddenly appeared on the crystal!

"Is it hot and cold to expand and contract...... That's a good way to do it. ”

Even Han Kun praised Karina. In the face of such a very hard substance, destroying it from the inside is often a good option, and Kailina uses the principle of thermal expansion and cold contraction to make the temperature of the crystal change drastically in a short period of time, thereby directly breaking down the internal structure of the crystal, and these cracks are also a proof of the success of Kailina's method.

Bang!!!

At this moment, the crystal in front of it shattered, revealing a hole half a meter in size. There was no doubt that Ao Bai appeared in Karina's field of vision.

"That's enough, it's big enough to get into."

"Don't rush in yet, I'm afraid that after you come in, the crystals here will change again. It was just the moment I stepped on the ground that I had this happening. ”

Ao Bai said lightly. Even when he was in a difficult situation, he maintained a considerable degree of calm.

"Well, but do you want a way to get through this transparent wall?"

"No, I can only test that it's a smooth wall. As for the thickness, there is no way to test it, and it is not even known what this wall is made of. ”

"Would you like to try what you just did?"

Han Kun glanced at Karina, but Karina shook her head.

"It's hard because the wall doesn't look like it's really there. The principle of thermal expansion and cold contraction is likely not to work. ”

"Then let's just use the Ventilation Ring. It's just a short distance movement of three people, and it's not a problem. ”

"What if, instead of a wall, it's a solidified space?"

"Solidified, space?"

Karina's words woke up Han Kun. If there is really a frozen space in front of you, then it completely makes sense of all the phenomena that happened when Ao Bai collided, with Ao Bai's fist to smash the space, I am afraid that it will be difficult for Ao Bai in his real state to do it.

However, Han Kun was able to use the Ventilation Spirit Ring to perceive the existence of space, and he could use the characteristics of Jia'er's body to tear apart the space.

"I'll try. In case of any danger, I will move to you with the Ventilation Ring. ”

Han Kun slipped through the breach opened by Karina, and used his magic to keep his body in the air so that it did not touch the ground, which seemed to have a good effect, and the space here did not seem to change again.

Han Kun placed his hand with the ventilation spirit ring on the air wall in front of him.

The hand did feel the texture of being blocked, and the ventilation ring was indeed attached to the wall.

"You're right, the space in front of you is indeed frozen."
