The giant magic ship roared away, hovering in the clouds until Sophia and her party sealed off the entrance to the ice-free river in the Altar of Shadows and returned to the surface to give a signal.

"Be careful not to touch the stream on the ground......"

Franconia picked up a pebble and threw it into the stream of liquid air, and in the blink of an eye the pebble was frozen and frozen, and slowly sank into the stream.

After seeing this example, Sophia swallowed and subconsciously tightened her robe.

It's just that apart from her, no one else has a special expression about it.

The Holy Maiden Elilia seems to be curious about the fairytale world of ice crystals around her - honestly, if you don't care about the meaning behind this ice crystal world, but on the surface, it is very beautiful.

The Holy Silver Sword Ji Frei was cautiously watching her surroundings, as if she was alert for some monsters to come out of the corner. Sophia didn't think it was necessary...... Even pure water elemental beings could not have lived in such a place as cold as it was unusual.

Theo was still unfazed...... Well, until now, unless Sivi was present, the girl's expression had always been like this, less varied than Francon's dead face.

As for Franken...... What special expression do you expect a dead face to have?

"It doesn't matter on the surface, as long as you don't deliberately step into it...... However, all of these streams seem to flow to the entrance to the Altar of Shadows. Once we're inside, I'm afraid it won't be so easy to walk. ”

Sophia surveyed her surroundings. showed a look that was not optimistic.

I'm afraid that the current Shadow Altar has long since become a valley-like environment, and it is still the kind of valley that kills every step of the way.

"These magic robes provided to us by Mr. Edric contain the power of divine light, and even if they are frozen up, they will not necessarily die immediately."

Frey said with a serious face.

"I don't want to know anything about this strange bean knowledge, and I don't want to experience it myself......"

Sophia sighed.

"Can't we make a raft out of that kind of frozen tree out there? After the pebble was frozen and cracked, it was only covered with ice, and it did not grow indefinitely, which means that the stream turned into air will not continue to freeze on the ice itself, right? ”

The Holy Maiden seemed to think for a moment, and then pointed to the icicle forest not far away.

"The specific gravity of the ice is probably heavier than this water, and the raft may not be able to float......" Sophia narrowed her eyes, "but it's still worth a try." ”

"I'll do the rough work."

Franconian folded his hands, and by the time he opened them again, he had an extra wand topped with a skeleton carved out of gemstones. There was also an eerie glow from the holes in the two eyes of the skeleton......

"Your aesthetic is really unacceptable." Once roamed the eastern plains. Frey, who had killed many necromancers, endured the discomfort that was surging in her heart and said in a cold voice.

Franconian smiled emotionlessly, and then a few ...... Well, it may be a creature like a skeleton that appeared in front of everyone's eyes.

"What is this? There is no breath of ordinary undead creatures at all, huh? Elilia leaned over the skeleton-like objects. Asked curiously.

As a light-friendly and strong to the point of a mess, Her Royal Highness the Holy Maiden. Her existence itself is highly poisonous to many low-level undead creatures. Even getting too close to each other will cause them a considerable amount of damage.

But now, let alone closer, even Elilia reached out and tapped their skulls, but it didn't hurt the strange skeletons.

"It's a kind of golem. The reason why it was made into the shape of a skeleton is to be able to better meet the driving conditions of necromancy, of course, the specific situation is not so simple, but because it has nothing to do with the current situation, I will not repeat it...... By the way, Miss Eliria's shot had already destroyed the magic circle I had carved into the brains of these golems. ”

As the screws on his head froze as he expected, Franconia could only continue to speak in that emotionless tone.

This caused Elilia to laugh dryly.

In fact, the production of these skeleton golems has invested a lot of money, and they can almost cope with most situations, but in the current extreme environment, after only working for less than half an hour, the joints of these golems have reached the limit.

And the rafts they made proved Sophia's conjecture that they would sink and be completely useless when they were put on the stream.

In the end, the crowd had to block all the streams outside, and after waiting for a while, Francon's newly released golem opened the way and entered the shadow altar.

The environment in the Shadow Altar was very harsh, except for the deadly stagnant water that had not disappeared, it was covered with frost everywhere, and there were many grass like ice clusters, making people feel like they had nowhere to put their feet.

But other than that, it's not without its good things.

"This is...... The Luminous Crystal of the Water Element?! Sophia looked at the glittering minerals embedded in the ice wall, and couldn't help but widen her eyes: "Doesn't it take at least a thousand years for the birth of Yaojing!" ”

"It's not so much the water element dazzling crystal, but the magic crystallization of the ice attribute......" Frankon looked at the crystals everywhere on the entire ice wall, and also sighed with some emotion: "But so many pure magic crystals are really rare...... If you don't count our college grocery store. ”

His words brought Sophia, who was thinking about how to move the ice wall back, to her senses.

The first task now is to deal with the cold invasion, and Edric has a lot of resources anyway, so he doesn't need to be in a hurry about so many magic crystals.

After a short rest, they continued to move forward, but the closer they got to the entrance of the ice-free dark river, the more and more various heavenly and earthly treasures of ice attributes, and Sophia even found the legendary 'Frost Heart' in some places......

By the time they reached the entrance to the ice-free river, treasures that were hard to find in the outside world filled almost the entire tunnel of the entrance.

"Professor Sophia, what do you think we should do?" Franken, whose eyebrows had turned white, asked Sophia with a smile, "If you go down to seal it, maybe you can get the treasure of this tunnel?" ”

But the tone still hasn't changed.

Thinking of Sivi's warning, coupled with the vigilance just now, Sophia did not indulge her desires.

"It's sealed here." She said resolutely, "Since this is what Dean Xiwei wants, I will not go against it." ”

Elilia on the side had a slight approving smile on her face.

Just as the group was about to seal it, an unfamiliar voice suddenly came from behind them.

"If you don't want it......"

In Frey's expression, "Are you finally willing to come out?", two men wearing the standard magic robes of the Qiyao Mage Association walked slowly, and one of the taller ones had a very kind smile on his face: "Why don't you leave it to us?" (To be continued......)

PS: Some readers questioned that air does not become liquid no matter how cold it is without pressurization.

The tirade is well-founded and convincing.

But the problem is, leave aside the fact that this world is a different world...... In the vicinity of the ice-free dark river, where even absolute zero has been broken through under the distortion of the law, even if the air can be liquefied, what is so strange?
