The dry well was very deep, and along the rope, Gray dived seventy or eighty meters before finally reaching the bottom of the dry well.

Click!

The sound of something being trampled on sounded, and Gray looked down, and it was a dry bone, and it was the lower leg bone that he had just stepped on.

On the battlefield, I don't know how many corpses I have seen, Gray is naturally not afraid of a single white bone, he squatted down and looked at this white bone.

The bones of the white bones have become extremely loose and fragile, and can be easily crushed by foot, at least for hundreds of years.

He raised his eyes and looked ahead, and there was also a skeleton not far away, and when he went over to investigate, he found that it was also a skeleton that was extremely old.

Looking in the direction where the skeleton had fallen, a deep passage appeared in front of him, and within the passage, there were more than 10 hazy white light creatures.

These white lights floated in the air, as if they had spotted him and wanted to fly this way, but when they were about to leave the passage, it seemed to be blocked by an invisible wall, making it difficult to leave the passage.

Like wild beasts seeing their prey, they let out unwilling whimpering, constantly hitting the invisible wall, but they couldn't hit it.

"Sure enough!"

Seeing these ghosts, Gray was not surprised, but showed a sure look.

He had already had a suspicion of this when he heard the voice before, and now it had been confirmed.

Gray has dealt with ghosts no less than once, seen abandoned villages full of ghosts, seen thousands of ghosts walking in the night, and also seen fox beasts that can manipulate ghosts.

Gray can be said to know the ghost very well, so after hearing the whimper, he immediately judged that it should be the voice of the ghost.

"I didn't expect the castle's secret room to be here!"

During a previous visit to the castle, Gray searched to see if he could find the castle's chambers, but found nothing.

Unexpectedly, the secret chamber of the castle was actually in this dry well, and if he hadn't heard the roars of these ghosts, he probably wouldn't have been able to find this secret room for a long time.

"Is it some kind of runic mechanism that keeps these ghosts at bay?"

At the entrance to the passage, as far as Gray could see, there was nothing, no walls, nothing like a barrier, but it kept the ghost out of it.

This made Gray curious, this was the first time he had seen something that could keep a ghost at bay.

He walked over.

Whining!

Seeing Gray approaching, the ghosts roared harder and harder, and kept pounding, but they were blocked by an invisible barrier, and they were never able to break out of the tunnel.

Drawing the sword from his waist, Gray tried to stab forward.

With his current strength, he is naturally not afraid of ghosts, and he definitely needs to explore the secret room this time, and he must enter this passage in the process, he wants to see if there is an invisible barrier at the entrance of the passage to close the passage.

The blade of the sword encountered no hindrance, and easily passed through the entrance of the passage and entered the passage, without the invisible barrier he had guessed.

Seeing the sword body stretched in, a ghost rushed towards this section of the sword body, and the cold aura that it carried on its body that could freeze people's souls immediately spread to the sword.

However, the sword is a dead thing, so naturally it will not be attached to these ghosts, and these ghosts will pass through the sword.

The unwilling ghost turned back and flew around the sword.

Cracking sound!

A trace of thunder and lightning ability attached to the sword, and a purple lightning suddenly appeared on the sword, for Gray, it can be said that it is less than 1% of the strength of thunder and lightning, but for these ghosts, it brings devastating power.

Just by the spark splashed by the thunder and lightning, these ghosts screamed, their bodies quickly disappeared and collapsed, and finally the dozen or so ghosts all dissipated.

Slashing all the ghosts, Gray reached into the tunnel, and his hand easily penetrated it, this invisible barrier that could keep the ghosts at bay couldn't stop him either.

Strode inside, such a secret room, he said that he would investigate everything.

As he went, he saw more than a dozen skeletons, the degree of weathering was not the same, obviously people from different periods, if Gray guessed correctly, those ghosts should have become after the death of the owner of these bones, this should be a place where ghosts can breed.

The tunnel curved downward, apparently deep into the ground, and the surrounding walls and floors were all made of a very hard stone that even Gray could hardly leave too many signs of damage on top of it.

This can't help but make Gray a little hopeful, the treasures in the secret room that can be built with such precious stone must be extremely precious.

Of course, I can't help but be careful, this secret room is probably indispensable to the mechanism, and the power of the mechanism is probably not small.

Especially the dozen or so skeletons before, Gray had examined, and all the bones were extremely well preserved, and there were no sharp blades or other wounds from other attacks, which made him wonder how these people had died.

Wave!

Suddenly, a strange invisible fluctuation suddenly appeared, formless and substantial, not visible at all, and imperceptible, and Gray had been swept away by this invisible fluctuation without even realizing it.

"Shhhh

Gray suddenly snorted in pain and pressed his hand hard against his head.

Just now, he actually had a pinprick feeling, as if his soul was being dragged outward by an invisible hand, like a radish plucking.

"What kind of attack is this......?"

Gray gasped, with his realm of a brute blood warrior, he had been hit unknowingly, and it was conceivable that this kind of attack was terrifying.

Now he finally understood how those people had died, and there was no doubt that these people must have been killed by this invisible attack, and it was because of this that their bones were able to remain intact, and there was not a single wound visible on them.

Those people were probably the ones who discovered the secret of this dry well before him, and wanted to find out for the treasure of the secret room, but died here without a trace.

"Could this be a soul attack?"

It doesn't hurt the body, but it makes people die suddenly, and the dead people become ghosts, so he has to suspect that this is a means of soul attack.

Although he had never seen a soul attack before, he was almost 90% sure that the attack he had just received was definitely a soul attack.

"This chamber may be even more dangerous than I thought!"

Gray's face was solemn, the attack of the soul was almost impossible to defend against, and the most terrifying thing was that it was only for the soul, the defense of the body was useless at all, even if the body was strong, the soul would be killed immediately if it was too fragile.

Fortunately, his current realm has reached the Brute Blood Warrior, and under the nourishment of his own realm, his soul must be more powerful than ordinary people, so he can withstand the ethereal soul attack just now.

"The last time I encountered a fox-type blood beast that can manipulate ghosts, I wonder if it will have a similar soul attack?"

He couldn't help but think that the fox-type blood beast that he encountered in a forest that could manipulate the soul, and he didn't know if that fox-type blood beast with desolate strength had a similar soul attack.

If that fox-type blood beast also mastered a similar soul attack, then he could be called extremely lucky at that time, and if that fox-type blood beast used a soul attack against him, I am afraid he would have avoided it at that time.

Originally, he also thought about hunting that fox-type blood beast for a while, although his current realm is only a brute blood warrior, his combat power has reached the desolate level, and he has even killed a desolate blood warrior, so it stands to reason that he already has the strength to hunt that fox-type blood beast.

But now that he thinks about it, he feels that it is too unsafe, if that fox-type blood beast has a similar soul attack ability, his strong physical defense will not have the slightest effect, after all, it is an attack on the soul.

"Do you want to continue?"

Gray's face was solemn, the danger of this secret room exceeded his estimate, it was only a preliminary in-depth, there was such a dangerous rune mechanism, if he continued to go deeper, would there be an even more dangerous mechanism?

"Could this castle really be an imperial building?"

Such a dangerous mechanism, even if it is not much more than the last mechanism in the King's Graveyard last time.

He had to suspect that this building was more glorious than the current Imperial period, and its owner's identity was probably not simple, even if it was the Imperial period, those who would build such a secret room must not be simple people.

"Probe further, and if it doesn't work, go back immediately!"

Gritting his teeth, Gray decided to go some further.

Although that invisible soul attack was dangerous and there was no way to defend against it, with his realm of a brute blood warrior, he should be able to withstand it.

Wave –

Gray walked forward cautiously, and every foot fell extra carefully, and after more than 10 meters, suddenly another wave of invisible fluctuations swept towards Gray, and Gray couldn't help but cover his head in pain.

After standing still for a moment, and after recovering, Gray continued on his way.

Wave, wave, wave!

After walking more than 20 meters, he encountered that invisible soul attack again.

Moving forward more than 10 meters, he encountered another wave of invisible soul attacks.

Moving forward more than 30 meters, he once again encountered a wave of invisible soul attacks.

Gray had already suffered four waves of invisible soul attacks, and the severe pain made cold sweat ooze from his forehead, and he was a little hesitant to continue walking.

"Huh, ahead?"

Turning a corner, suddenly, he found that dozens of meters in front of him, there was no longer an empty tunnel, but a room with stone platforms and other furnishings, obviously almost arriving at the secret room.

The secret room was in front of him, and he couldn't give up at this time, so he gritted his teeth and continued to move forward.
