For Thunderlin, he collected advanced meditation methods to replenish the chip library and deduce the contents behind the Pupil of Como and the Holy Light Candle.

Under the powerful amount of computing power of the chip, it doesn't matter if it is a little crippled, and as for the difficulty of promotion, it is not a problem, anyway, Lei Lin will not cultivate by himself.

"Alright! I've seen your sincerity!"

Under Xi Ling's somewhat stunned gaze, Lei Lin threw the pale golden leaf with the crystal mask recorded directly back to Xi Ling, and said lightly: "I want to enter the ice cave alone now......

"My lord, the terrain of the Ice Cave is very complicated, even if there is a map, let Obo or Elijah, or Xiling personally lead the way, right?"

Xi Ling's face was anxious, this was a good opportunity to get closer to Lei Lin, and she didn't want to miss it.

"No need!"

Lei Lin directly refused.

He has a lot of secrets that are not convenient to show in front of others, and it is even more difficult to display them with people, and, according to the analysis of the chip, the breath of the Ice Scorpion is that the higher the level, the better the quality of the Ice Scorpion, therefore, Lei Lin also hopes to go all the way to the lair of the Ice Scorpion, hoping to find a higher level of this creature.

For such a dangerous creature whose even an ordinary adult body is the strength of a formal wizard, two third-class apprentices are simply a food delivery.

Even if Xiling goes, it will be more than lucky.

"Then, please inform me when you come out, Xiling hasn't brought you to our school yet......"

Xiling bit her lip and finally sent out an invitation.

"I will!" Seeing her look like she wanted to say something, Lei Lin smiled in his heart, but agreed directly.

Then, Lei Lin followed Xi Ling to the entrance of the Ice Cave.

"Here by the Nature's Alliance octopus. Verdant vines...... The forces of the six schools are jointly guarded, and the common Senate is jointly in charge of this place, and our Natural Alliance School still has very large power in the Senate before. But unfortunately, since the death of my mentor. The Covenant of Nature's voice is getting smaller and smaller, and it has even been squeezed to the bottom of the table......"

Xi Ling took Lei Lin to walk inside the huge building, and from time to time introduced Lei Lin to the current situation of the Natural Alliance.

And on the way, Leylin can also see wizards and even apprentices wearing various wizard robes and wearing different markings from time to time.

"It's called the Ice Fortress, and it's been built by our six schools and defended by men. There are also many schools that have set up special laboratories here to analyze the various materials obtained from the ice caves...... Although now our natural alliance has very little say. But it's not a problem to send adults in. ”

Xi Ling said as she led Lei Lin to the bottom of the fortress.

In the middle of the artificially dug cavern underneath, Lei Lin saw a huge white crack.

The cold wind continued to pour out from the cracks, causing the temperature inside the cave to drop by more than ten degrees immediately, and even the white water vapor continued to condense into ice and snow, covering the entire crack in the ground with a thick layer.

"The Ice Cave is permeated with this kind of ice wind all year round, and the cold attacks and ice blades attached to it are even tricky for us official wizards. After years of exploration, we found that only here is the crack with the least attack and the best place to enter. And the rest of the places are either desperate, or they will face the invasion of cold for a long time, and even second-level wizards may not be able to withstand it......"

"Hmm!" Leylin nodded.

There are also huge cracks in the ground outside the Ice Cavern. But looking at the attitude of these wizards who ignore reason, you know that those entrances are simply dead places, and only here is the safest way.

"Isn't this Wizard Xiling, who wants to venture into the Ice Cave?"

At this time, a wizard guarding the entrance also greeted him, smiling at Xiling, with a little eager look in his eyes.

And Leylin looked at the white beard that the wizard had dragged to the ground, and rolled his eyes a little speechlessly.

"No! I'm here to see an emeritus professor from our school in!" replied with a smile.

"Professor Emeritus!"

The old man was taken aback at first, and then looked at Lei Lin, the new wizard, in disbelief.

Although with Xiling's ability. She can't recruit too powerful wizards, but some of the more obsessed with her formal wizards. But it's also very willing to get close to the beauty by joining the alliance of nature, but it's a pity. This was all rejected by Xiling.

According to her faint disclosure, she hoped to find a wizard with at least semi-elemental strength or above to join, but it was obvious that among her admirers, only Sgrid met this requirement, but the other party would not agree at all.

"Hello, young wizard, my name is Old Made!" the old wizard looked at Lei Lin with a scrutinizing gaze, but he spoke very politely.

"My name is Lei Lin, fortunately!" Lei Lin smiled very reservedly.

Moreover, because of his habit of compressing his mental power at all times, he suddenly hid his own breath and energy fluctuations well, so that Old Mader could not discover the reality and reality.

But even so, it was enough to arouse the attention and jealousy of Old Made, the unknown is often dangerous and terrifying, especially for wizards.

"Since you are an honorary professor of your college, of course you can go in!"

After receiving the confirmation, Old Mada seemed very businesslike.

Immediately, he pulled out something that looked like a metal ball, and from it shot a red ray of light, which sank into the entrance.

There was a faint tremor in the void, and the invisible distortion continued to explode, revealing a red glowing fishing net, covering the entire entrance, this net was obviously a defensive means that had been laid out before, but I didn't know how to hide it, and even the spell fluctuations did not leak in the slightest.

"This arrangement?" Leylin muttered in his heart, "If I hadn't known beforehand, maybe I would have found out!"

"The ice cave is very dangerous, there is a cold wind everywhere that is comparable to a zero-level spell attack, and there are many high-energy creatures gathered, please try not to go deeper!"

Old Mada gave a few words, and then made a gesture of please to Leylin.

"My lord, the ice scorpion's cold attack has an extremely cold nature, please be careful!" and Xi Ling finally said to Lei Lin.

This kind of scene suddenly made the old Mada on the side a little red, but he didn't say anything.

Unlike Scott, he just has a simple love for beauty for Xiling, but there is no perverted and terrifying possession**.

Therefore, when he saw that Xiling faintly wanted to throw himself into Lei Lin's arms, he just chose to watch from the side.

"I'll be careful!"

Lei Lin smiled and agreed, and after nodding to Old Made, he disappeared directly into the wind and snow.

......

Whew!

The cold wind was howling, and a violent air flow was blowing in Lei Lin's ears, and Lei Lin's whole person was sliding down rapidly.

Eventually, with a soft sound, Leylin was firmly on top of the snow.

"This depth is already more than three thousand meters underground, isn't it?"

Accompanied by the howling cold wind, there was a large amount of noise, as if ten thousand musical instruments were playing.

Unlike the wizard fortress above, which is always lit with eternal light, the icy caverns underneath are plunged into darkness.

"Light Technique!" Lei Lin raised his right hand, and a ball of light like a bright incandescent lamp appeared in the palm of his hand.

"Go!" With a soft cry from Leylin, the ball of light quickly flew out of his hand, rose into the air, and circled in circles.

The long-lost light immediately illuminated this place.

Leylin glanced around, and the place where he was a semi-circular underground ice cave, with countless dense holes around it, like an ant's nest.

The surrounding walls were covered with a thick layer of translucent ice, and the light of the Illumination Technique reflected off the ice, reflecting a colorful light, and everything looked beautiful.

Poof! poof!

The sound of a large number of flapping wings, as if tens of thousands of sparrows were neighing together in a sack, made Leylin wake up from this beautiful scenery.

Immediately, a large number of black dots poured out of the various passages.

Up close, the black spots have a pair of fleshy wings, a tail that is forked like a swallow, and tiny eyes and pointed ears give the skull an even more hideous look.

"There are at least 10,000 bats every day!" Leylin quickly estimated the number of bats.

"Squeak ......" the numerous bats screamed, surrounding the ball of light, like a dark cloud surrounding the sun, casting a fine projection on the ground.

"Squeak!" After the bats surrounded the ball of light for a while, as if they had received some order, they began to rush upwards in one go, and their fleshy wings continued to flap, wrapping the ball of light in its entirety, revealing no light.

The whole cavern was once again plunged into darkness.

A moment later, as the sound of wings fluttering sounded again, the numerous sun-chasing bats dispersed, and the ball of light in the middle was gone.

"Alas......" Leylin sighed, "It is very dangerous to light a light in a dark place......"

In the underworld, the Dark Polar Domain where humans live is only a small part, and most of the dark beasts here have been completely wiped out, and more dark beasts can only choose to retreat after seeing the light due to their weak strength.

But beyond the Dark Extreme, there are some inaccessible places, and this light will instead inspire the ferocity of the Dark Beast!

The dark beast outside the Dark Polar Domain is completely different from the dark beast on the road before Thunderlin.

The beast tide composed of a large number of extraterritorial dark beasts has to avoid the edge even if the official wizard sees it. (To be continued)
