Over Dragon's Back Mountain, the world will show you a different side of it. Compared to the colorful world south of the mountains, the open frozen soil north of the dragon's spine is like a reserve area left by the Creator for future creations, with nothing but soil and snow and nothing else in sight. But that's not the case, if, I mean, if you have the guts to cross Dragonspine Mountain with reasonable and sufficient supplies and equipment to reach this land, then when you actually stand on this frozen land, you will find that it is not as eternal as you imagined, and there are many things hidden under the snow, including many ruins with man-made traces, and even some ruins that are even more beyond people's imagination. Of course, this does not include the Grey Tower.

Because the Grey Tower is not a relic, it is not buried under snow and ice. Although the apprentices trained in this building have some suspicions that the underground part of the Grey Tower may be much larger than its above-ground part, due to the chaotic spatial structure of the building and the many hidden rooms and secret doors, even the Grey Robe who has been trained in it for many years has to admit that he has not seen all the secrets of this building. The only person who can control everything in this tower is its founder.

In terms of appearance, the Gray Tower is nothing special except for its height. The tower towers like the only tree on the ice sheet in a ring of slightly protruding rings, with only a low path to the south. That being said, finding this path hidden under snow is not easier than knowing that it exists, as the entrance to this path changes over time and season, and finding it requires great magical skill and an understanding of the movement of the stars. This path is called the right path by the grey-robed people.

In contrast to the righteous path, there must be other ways to enter the Grey Tower, such as Cheese used to teleport magic and rode a dragon directly back to the Grey Tower. However, according to the regulations of the first gray robe, the gray robe that has left the gray tower for more than one year must return through the righteous path when returning to the gray tower. This means that the wizard is still eligible to step into the Grey Tower. As for those who don't know anything about it, but only see the Grey Tower and want to get closer, they will find that the hills are far more impassable than they expected. By the time they had traversed the hills and thought they had reached the heart of the Grey Tower, they would be surprised to find that the tower had disappeared in the snowstorm. And they had reached the other side of the ring.

It had been more than a year since Cheese and Raven had left the Tower, so they had to enter the Tower through the Path. The two of them slid off the dragon's back by the side of the hill, allowing Migo to enter the tower first. As Cheese's companion and the dragon who befriended the Grey Tower, Migo has his own room in the Tower.

"Alright, let's hurry up and get inside, this place is still as cold as ever. Cheese looked at the snow around him and tightened his clothes. Even after living in the Northland for a long time, the cold wind on the frozen soil still made him feel uncomfortable. But this discomfort is mixed with familiarity, and this coldness is a feeling that he has been familiar with since he was a child.

"I partially agree with you. But it's here anyway, so I think it's better for us to prepare first. "The state of the cursed crow is much worse than that of Si, he has lived in the warm area for too long, and the cruel cold almost freezes the sorcerer's lips together. But even so, he didn't choose to start looking for the entrance to the righteous path immediately, but after looking around, he took out a monocle with crystal lenses from his bosom. Even without using magical vision, Cheese could see the strange light reflected off the lenses of that glass.

"Prepare what?" the mage was slightly confused, but soon understood what the crow meant. Since the gray robe who has been away from the tower for more than a year must take the right path to return to the gray tower, it is also the best place to investigate the traces of the gray robe near the right path. The entrance to the path requires the use of mana, so it is entirely possible to use this to find out how many or even how many Grey robes have opened the path in the recent past by searching for nearby mana. This is also the reason why the crows do not directly use the magic vision but use tools to search for these traces, the gray robes will more or less be aware of the traces of magic left by themselves, and directly touching the magic power with magic power is like telling the other party that he is being tracked face to face.

Raven didn't answer Cheese's question after seeing his expression of understanding, but instead took advantage of the properties of the crystal lenses to look around carefully, hoping to find a color that symbolized magic. Mages have also heard of this kind of prop, and crystals have always been used as mirrors, especially lenses. In the process of cutting the crystal mirror, some craftsmen are surprised to find that the world can be seen in the crystal mirror with certain specific techniques, because the light that reflects the original color is accepted by the crystal and separated by refraction, so that the thing appears behind the lens to show a different color from what is seen by the naked eye. And in the midst of this separation, sometimes you can glimpse beyond the light.

Therefore, strictly speaking, the lens in the hand of the crow is not a magic item, it is just a crystal that has been cut with a special technique to see the magic power. However, this cutting technique has traditionally been in the hands of the caster and a very small number of craftsmen associated with the caster, so it is not inferior to the so-called magic items. This expensive prop is a bit of a frustration for the Greys, all of whom have the ability to use magic to see the world, which allows them to easily see a clearer and more definite vision than in the crystal. Cheese did not believe that the Cursed Crow, who had always adhered to the principle of efficiency, did not know this, and he brought this eye for the purpose of covertly searching for traces of his fellow disciples.

Was it so bad? The mage didn't ask, knowing it would make him stupid in the eyes of the crow and get no real answer. Cheese looked up at the tall gray tower that stood in the middle of the hills, he didn't think it before, but now, for the first time, he felt that it was too tall. It was as high as if it would take him a lifetime to climb to the top of it.

"What are you doing? We're going to open the door. The crow's disgruntled voice interrupted Cheese's thoughts, and he had finished gathering clues.

"How's it going?" the mage asked, realizing that there was no need for the crow to share information with him as the sorcerer hesitated for two seconds before he spoke. But the crow said anyway, but was that all he had seen?

"Two, two of them opened the door and went in for thirty sunsets. I didn't check for any signs of the reverse opening of the door, maybe they left through other channels, maybe they were still in the tower. As for whether there are any guys who came back earlier, it's hard to say. ”

"Which two?"

"Jewelers and sleepy bugs. ”
