On many occasions, my fellow crows have been regarded by outsiders as outliers in the Grey Tower. In their opinion, his actions were too far removed from the usual style of the gray-robed mage, and in his deeds, people often did not see respect for this infinite world and a thirst for knowledge, but only the means of quick success and the perverse character of the curse crow.

But that's not true. No Grey Robe, including me, would have regarded our fellow magic-wielding fellow as an outlier, and in his fearsome style, the Raven shared the thirst for truth with the other Grey Robes. And his eagerness is also because he is aware of the inefficiency and inaccuracy of language communication, and the means he uses to solve it. Overall, no matter what my fellow has done, he is a respectable spellcaster. —Cheese's personal notes

The sewers of the Molten Iron City may no longer be called a sewer, because there is not a trace of household waste in the complex and winding underground corridors. Raven sat on the dry wall for a short rest, he didn't know how long it had been since he had entered these strange pipes, the concept of time had no reference in the dark underworld, but in terms of mana, the sorcerer believed that the outside world had not yet fallen at night.

But what's the use of that? the damn underground tunnels seem endless, and even Raven once suspected that they were larger than the Molten Iron City's surface area. Moreover, although the sorcerer did not know the sewer system, he could also see that the layout here was not normal, such as the intersection where he was resting now, there were four notches left by magic on the wall in the corner, these marks could only be noticed by the caster, so there was no possibility of forgery. In other words, he's been here four times.

At the same time, the wizard also noticed one thing, the height of these corridors is not fixed, and many times the passages will suddenly slope up or down, which also makes the cursed crow even more confused, are these passages really made by the Hammer Grand Duke? What is the purpose of such a large project? The smell of conspiracy permeates the lightless underground. Whatever the purpose of building this place, the sorcerer had a hunch that he was close to answering.

The thirst for secrecy made the Raven ignore his fatigue, and he held his hand against the wall and stood up again. His eyes glowing with magic scanned the three passages in front of him, all three of which he had walked before, and had been brought back to this intersection without exception, there must be something he didn't realize could get out of this predicament, the magician thought.

With the superhuman memory of the spellcaster and the construction ability honed by years of spellcasting training, a map he explored quietly took shape in the wizard's mind, every corridor he walked, every fork in the road he saw, the ups and downs of the road, these factors made this map quickly change from a flat surface to a three-dimensional one. It would take months for even the most seasoned miner to memorize such a complex terrain, but a few breaths would be enough for the Grey Robes.

"Oh, I found it. The silence of the environment forced the Raven to express his excitement in a self-talking way, and the light in his eyes was even brighter, because in just a few minutes of combing, he had found the hidden core of this underground labyrinth. The up-and-down twists and turns of countless pipes are all about making people ignore the difference between high and low, just to get used to it and get lost in this ups and downs, to ignore something.

"Here, right?" said the Raven, carefully measuring the changes in the passage with her footsteps, smiling as she made some distance towards the top of the passage. According to his calculations, there is a carefully hidden space on this passage, which is about the size of a two-story villa. As for the corridor next to it, it now looks like a silkworm chrysalis wrapped around this space, carefully protecting the softest core.

"Come on, let's see how we get in. With a snap of his fingers, the firelight appeared in the dry passageway, and the crow knew it would attract some of the creatures that inhabited the area, and he had noticed the activity of other things many times during his aimless wandering, but the sorcerer had chosen to avoid them all to be on the safe side. But now it doesn't matter so much, the night vision brought by magic is not enough to find delicate mechanisms, after all, human eyes are organs born in the light.

"Huh...... closed his eyes to allow himself to adjust to the fire in his hand, and the crow let out a sigh of relief, he felt that his heart had not beaten so fast in a long time. Even when fighting the nezumi, the sorcerer did not have this pleasure, this thrill of revealing a secret. Eyes opened, and the sorcerer noticed that the walls of the hallway here were in the light of a completely different material from the sewers, which looked more like some kind of metal.

"Knock, knock, knock!" a heavy sound came from the far reaches of the passage as the sorcerer carefully slammed his free hand against the metal wall, trying to find a dark grid between the lines on the wall that could be pressed or slid in. It sounded like heavy rocks pounding against the floor, a sound he'd only heard once in his life.

"Hell, how can there be giants in this place?" the wizard's hand quickened, his eyes eagerly searching for unusual places in the pattern, although he didn't know why it was here, but the crow was very sure, only those beings called giants could make such a sound when they were running fast. No matter what kind of giant lived in the underground pipes of the Molten Iron City, the sorcerer had no interest in meeting them.

"Knock! knock!" a violent echo approached. Although the gray-robed mage tried to tell himself that the louder voice was due to the echo in the channel, it did not allow his trembling hands to stabilize himself in the face of a giant in such an adverse situation... The sorcerer began to wonder if it was his time to die.

"Damn, shit, shit!, where!" the wizard cried hysterically, he could feel the ground tremble, and the giant could come out of the surrounding passage at any moment and crush him to death. At this time, his right foot slammed on the floor of the corridor with excitement, and with a "click", the body of the cursed crow sank, and he stepped a small brick into the ground.

Stiffened, the sorcerer's body completely froze. Although the giant's footsteps were still approaching, the cursed crow did not move, and cold sweat flowed down his forehead into his eye sockets. The wizard wasn't sure what he was stepping on, maybe it was a secret door that would allow him to escape, but it could also turn him into a hedgehog when he pulled his foot out from the crossbow arrows fired from both sides of the hallway.

Following the light of the flames, the crow could see a large hand covered with abscesses appear in the corner of the corridor in the distance, and in the name of the Gray Tower, the heavy hair on that hand almost caught up with the blanket in his room!

Regardless of whether the giant who was rushing towards the crow from the passage was friend or foe, he was clearly running too fast. Although the large hand managed to grasp the wall around the corner, the huge kinetic energy kept the giant's body in a forward position, and his long arms could not make him turn as expected. As a large black shadow flashed, the Great Hand and its owner rushed across the intersection facing the Cursed Raven.

At the same time, an iron basket-like object was lowered down the top of the passage. The sorcerer didn't even think about it, and stepped into the hanging basket. After feeling the weight, the gondola, which had not been activated for an unknown amount of time, made a screeching sound and disappeared into the roof of the corridor with the mage in it. When the basket stopped rising, the Raven could hear an angry roar coming from directly below.
