"A rune mechanism's control hub?"

Gray doesn't have many rune items, but it's not a few, and the noble families will have some rune items more or less, such as a drying room that allows clothes to dry quickly, such as a rune lamp that lights up at night, such as a stove for heating in winter, and so on.

And both the original Fergus Castle and the new Fergus Castle are built with rune traps.

Of course, it is only the simplest rune mechanism, and it has no ability to attack, only the effect of opening and closing the rune lamp in the passage, or opening the exit of the escape passage.

Ordinary rune masters can only do this, if you want to have a certain attack ability, you must ask the rune master to take action, and if you want to have a strong attack power, you must ask the master of the rune master to take action.

The cost is really expensive, and these things require connections, and the Fergus family at the time of building the castle did not have relevant connections, so after thinking about it, the Fergus family finally decided to hire only ordinary runemasters.

The metal plate in front of him seemed to him to be the control of a rune mechanism.

Gray reached out and touched the metal plate, and then a trace of blood poured into a line on the metal plate.

There was no reaction, the power of blood poured into it, and it was like a stone sinking into the sea, and there was no reaction at all.

Gray was not discouraged, and the power of blood was re-infused into another pattern.

More than 10 lines were changed in succession, and there was still no change in the slightest, just when Gray was about to give up.

Buzzing!

Suddenly, the space of the secret room shook slightly, and then Gray saw that on the innermost side of the secret room, where there should be no gaps in the slightest, there were actually 10-ton boulders rising, and finally a strange door that allowed two people to pass through appeared.

"And the secret room!"

Gray's eyes narrowed slightly.

Originally, he was curious about how there was only such a secret room in such a place guarded by a powerful mechanism, which was really a bit abnormal, but now it seems that there are no other secret rooms, but the entrances to these secret rooms are covered.

Through the door, Gray looked inside.

Behind the door was a large room, beautifully built, with frescoes on the walls, runic lamps overhead, all lit, surrounded by white jade pillars, and stone carvings.

Gray walked in with his feet up, and looked around, and the more he looked around, the more he realized that this place did not look like a secret room, but like a castle hall.

"It's actually built like this, could it be that someone once lived here for a long time?"

Gray wondered what kind of person he was living in a dry well.

Looking around the underground hall, he soon discovered a number of rooms connected to the hall.

Pushing open the almost decaying wooden door, I entered a room on the left, a room that resembled a conference room, filled with tables and chairs, but all rotten.

Walk into a room on the right, it's a big room, there's a kitchen counter, there's pots and pans, it's a kitchen.

After some distance forward, another room appeared, and Gray pushed the door open and walked in.

Directly across from him was a huge bed, and there were several wardrobes on the left and right sides of the room, which was supposed to be a bedroom.

After searching the room for a while, but to no avail, Gray continued on his way, and saw another door again.

Although this door is made of wood like the other rooms, the wood used seems to be extremely special, and even after such a long time, there is no sign of decay.

"What's in it with a special kind of wood for the door?"

Gray was curious, pushed the door open and walked in.

What caught the eye was a small room, with two rows of bookshelves sparsely placed on top of which hundreds of leather-covered books were sparsely placed.

It has not been cleaned for a long time, leaving the bookshelves and these leather cover books covered with dust.

Gray walked over and carefully dusted off one of the leather-covered books, and took the leather-covered book out.

"Fleshly abilities!"

This is the title of the book, which appears to be an introduction to the abilities of the carnal type.

"I wonder if the paper has decayed?"

From the name alone, Gray could tell that the value of this book must be quite high, after all, this is a book about physical abilities, whether it is in the empire or in the kingdom, books about this kind of content are extremely valuable.

He was a little worried about whether the paper in the book would rot.

He carefully turned the pages, and then breathed a sigh of relief, the pages were badly yellowed, but they had not rusted, and the words on them were still legible, although they were somewhat dim.

Obviously, the paper has been processed, and the special door on the outside has a strong effect of insulating moisture, which also prevents the decay of the paper to a certain extent.

Gray looked at the other books and found that some of them had rotted due to poor paper, while others were made of paper similar to that of the Flesh Abilities book, and had not decayed as a result.

After putting the dozens of books that were not decaying into the purple ring with great value, and after looking for nothing else, Gray left the room.

Ahead, we had reached the end of the room, but at the end, a corridor two or three meters wide appeared.

The corridor is more than 100 meters long, and there is a silver metal door at the end, even if so many years have passed, the door is still shining silver under the illumination of the light, and there is no trace of decay.

Gray lifted his feet and walked down the hallway, just a few steps inside.

Swish!

Suddenly, Gray felt a flash of blue light in front of him, and it was coming straight at him, the speed was so fast that he didn't even have time to dodge.

He only had time to metalize his body when he was hit by the blue light, and his body flew out uncontrollably, into the hall beyond the hallway.

Gray looked down at his chest, where the aristocratic clothes on his body were completely shredded, and under the clothes, on top of the bronze skin, a deep wound appeared, and a large amount of red blood was spilled.

He was seriously injured!

Gray couldn't believe it, even the attack of the Desolate Blood Warrior on the battlefield could hardly be able to seriously damage the strong defense, and he was actually seriously injured under the blue light just now.

The power of that blue light, although not as powerful as the destructive power of a desolate blood warrior using a blood technique, was not far behind.

"What a strong rune trap!"

At that moment just now, Gray noticed that in addition to the blue light, there were rune patterns flickering in the entire passage, on the walls and even on the ground, and it was obvious that there were rune mechanisms in that passage.

And being able to make the defense as strong as he is seriously injured in an instant, the rune mechanism is strong, it is certain.

The rune mechanism in front of him was even more powerful than the last rune mechanism in the King's Graveyard.

If you really want to compare, the power is probably comparable to the large runic mechanism on the outermost part of the King's Graveyard.

"With such a small space, it stands to reason that it shouldn't be possible to formulate such a powerful rune mechanism!"

Enduring the pain, Gray looked into the passage, and immediately understood why there was such a powerful rune mechanism.

The walls, ceilings, and floors on both sides of this passage are all made of a purple jade material, and this material is the top-grade rune material Purple Lazuli.

The extremely extravagant rune mechanism made of purple lazuli, no wonder it has such power.

"Guarded by a rune mechanism made of purple lazuli, and made of silver metal, it has not decayed even after an extremely long time, what is in this room?"

Gray looked at the silver metal door in the depths, and it must be extremely precious and valuable to be able to be guarded by such a powerful rune mechanism.

"I'm afraid this is the real secret room, and the secret room outside is just a place to hide people's eyes!"

Obviously, the most valuable thing must be behind the silver metal door, and the secret room outside, which is nothing more than a fake secret room to disguise the existence of this secret room.

The fake secret room is full of the blood of king-level blood beasts, and it is difficult for Gray to imagine what kind of things will be in the real secret room, even if there are silver-level magic weapons in it, Gray will not doubt it.

"With my strength, I can't get close to that silver metal door......"

Staring at the silver metal door, Gray's eyes flickered, and finally shook his head helplessly.

"Even if my strength reaches the second level of the brute level, I'm afraid I won't be able to do it......"

The outermost attack alone already had such a terrifying power, and Gray estimated that in the depths of the corridor, the power of the rune mechanism would probably be even stronger.

"Just give it a try!"

Gray pulled out a battle axe, which was a bronze magic weapon, but the quality was only average among the bronze ranks, and it was one of his trophies on the battlefield.

The metal ability was activated, and Gray controlled the battle axe, and flew quickly inside.

The next shocking scene appeared before his eyes.

Boom, boom, boom!

Cyan light appeared one after another, slashing at the tomahawk, which was slashed and rolled in all directions, first hitting the ground, then bouncing off and hitting the wall on the side......

Control its trajectory with difficulty, and make it move deeper into the passage.

As the tomahawk went deeper into it, the number of cyan rays became more dense and the color became darker.

Sonor!

The metal handle of the tomahawk actually broke under the attack.

Gray continued to control the torn tomahawk and fly inside.

Sonorous, sonorous!

Eventually, the entire tomahawk was shredded into countless small pieces of metal and scattered all over the ground.

A bronze-level magic weapon was actually damaged like this, leaving Gray's back with cool air.

No matter how strong his defense was, it was definitely impossible to compare to a bronze-level magic weapon, and even a bronze-level magic weapon had been split into pieces, let alone him.

"The existence of the second level of the desolate level, if you want to break through, it should be difficult, and only the third level of the desolate level has some possibilities, and you must be absolutely sure, I'm afraid only a king-level warrior can do it."
