The light spectrum of a magic match is slightly different from that of a regular match - and that's all Duran knows, of course.

The advanced knowledge involved in this, such as alchemy, law and witchcraft, is probably only a few wise people in the world who can explain it, and the general situation is like this: this unusual light is refracted in the red transparent fluorite, and an optical change will undergo to form a new detection light. The Detection Light hits a normal rock surface, effectively penetrating walls that are more than three feet above the ground to find the secret or secret door behind it.

As an Assassin who didn't specialize in this, Duran only needed to know how to use it. He carefully controlled the tempo and maintained a certain pace of advancement.

After about three minutes, the corridor was still endless, but he wasn't too worried. Because Duran had glanced into the forge room before, and found that the room was so large that at first he thought that the little bit of fire was coming from the forge room.

The stone walls on both sides were still cold, and the elite ghost baby had not appeared, and Duran muttered a little in his heart. After all, it is also very tiring to maintain a high level of perception and vigilance for a long time, and if the other party hides in the shadows and competes with Duran for patience, it is undoubtedly the former that has more advantages.

And the small half box of magic matches was consumed, and the storage room in Amuse's mouth was still clueless, and he also felt with some regret that he might not have anything to do with that storage room.

"Smack!"

Duran took a deep breath and lit a magic match again.

Warm light refracted on the surrounding stone walls, illuminating the white rocks a dull red. He took a slight half step forward, and at that moment, the corners of Duran's eyes shrank sharply.

In the afterglow, a rock in front of the left was irradiated by the red light, but was not reflected back, but was absorbed by the rock, and in the blink of an eye, a vacuum of red light was formed.

"Found it!" Duran was overjoyed, and he stepped forward quickly, bringing the candlelight and the fluorite closer.

It turns out that it is this large area that does not reflect back the red light, while the rest of the place is literally a sea of red.

"Behind this stone, most of the secret door is hidden." Duran extinguished the match and pressed it with his hand.

Tactilely, this stone was no different from any other wall, and Duran touched it up and down for a while, but still couldn't get in.

No switches, no mechanisms, no clues.

Duran's brow furrowed slightly, and he tapped lightly on the wall, trying to listen to the echo.

"Knock Knock Knock ......"

The faint echo of the walls convinced Duran that the secret door must be right after that, for the rest of the hallway, however you struck it, the echoes were thick and dull.

By this time, magic matches and fluorite were no longer able to help Duran. He put the tools away and took a small shovel out of the lockpicking tool. This shovel is similar to the multi-purpose sapper shovel used by the army on Earth in Duran's previous life, and is designed to fold and shrink, making it very easy to place. The tip of the shovel is forged from the finest Mirvare steel, which is very solid, and it is very handy for both shoveling and prying.

Duran tapped the surface of the rock with his shovel, and according to its texture, he finally found a gap. He aimed the tip of his shovel at the crack and thrust it in.

Not surprisingly, the gap itself was not very strong, and under Duran's brute-force cracking method, there was immediately a hint of loosening.

Duran continued his efforts, and in a short time, he unloaded a large rock directly from the wall.

In the dark corridor, he couldn't see what was behind the rocks, and he could only light the torches for now, and he didn't care if he would alarm the enemy.

The firelight lit up from the darkness, and Duran, who had been walking in the dark for a long time, was slightly uncomfortable. He narrowed his eyes slightly, and it took a moment to see what was behind the rock.

A mud wall made of soft soil with a small keyhole in the center.

Seeing the appearance of this keyhole, Duran couldn't help but breathe a sigh of relief, it was the best way to enter the storage room normally. Although he was 90% sure that he would be able to violently break through the secret doors and other mechanisms without the key given by Amus, there would be a lot more unnecessary risks in the end.

He inserted the key to the storage room into the keyhole and rotated it ninety degrees to the right, but the mud wall did not respond. So he turned ninety degrees again, and this time, a slight tremor spread from under Duran's feet. Silently, the mud wall parted from the middle, revealing a small space hidden behind it.

Duran retrieved the key and calmly jumped into it.

As he finished his movement, the mud wall closed again, and Duran could feel the spinning sensation coming from under his feet—"Sure enough, this storage room can move." I don't know what kind of architectural design and mechanical technology can achieve this."

Duran calmed down a little, and put the torch on the shelf to the side, and the whole storage room was displayed before his eyes. The space is actually very small, with two rows of shelves on the left and right, and a long table and chairs in the middle, on which are scattered things.

This situation made him temporarily let down his vigilance, after all, this space is very small, and it is clear at a glance every corner of the past, and it is impossible to hide any monsters.

As for the mechanism mentioned by Amus, it would be a great irony for an assassin to die on the mechanism. What's more, Duran has been trained by the Shadow Thieves, and the basic protection measures are still understood.

His gaze withdrew from the table and began to examine the items on the left-hand shelf.

This row of shelves was divided into three levels, and Duran's eyes were initially attracted by a heavy-looking iron box placed on the top layer. The iron box was so large that it took up almost half of the space on this floor, and several things were squeezed into the corners.

And the unique pattern on the box also makes it even more eye-catching.

"The blood rune of the dwarves of the Blue Mountains?"

Duran recognized the origin of the iron box at a glance. As the favorite race of the gods of forging, the dwarves often possess extraordinary talents for blacksmithing. Whether it's the limestone dwarves who are well-versed in the distribution of underground veins and ore processing, the Blue Mountain dwarves who discovered new veins after a long migration thousands of years ago, or even their distant cousins in the underground, the evil gray dwarves, are all very good at forging items, weapons, and all kinds of equipment that make the mouths of other races, especially humans, water.

And Duran, who was familiar with the characteristics of the various races on the Fernand Continent, knew deep down that the dwarves of the Blue Mountains would not casually attach their signature runes to an ordinary iron box. Only the proud works that belong to them are worthy of the glory of the Blood Crow Rune.

Duran examined the shelves, then cautiously ruled out the possibility that there was a connection between the iron box and the shelves, and then reached out and moved the box to the table.

"Yo, it's pretty heavy." Duran let out a sigh of joy, a gleam in his eyes.

The heavier the box, the more precious the contents are, which is a special habit of dwarves when storing good things.
