The dry well was very deep. Following the rope, Gray dived for a total of seventy to eighty meters before finally reaching the bottom of the dry well.
Crack!
The sound of something being crushed was heard. Gray looked down and saw that it was a skeleton. The thing that he had just crushed was the calf of this skeleton.
On the battlefield, he had seen countless corpses. Naturally, Gray was not afraid of a mere skeleton. He squatted down and looked at the skeleton.
The bones of the skeleton had become extremely loose and fragile. It could be easily crushed by foot. At least a few hundred years had passed.
He looked up and saw that there was another skeleton not far away. He walked over to investigate and found that it was also an extremely old skeleton.
Looking in the direction where the skeleton had fallen, a deep passage appeared in front of him. In the passage, there were more than ten hazy white light creatures.
These white lights were floating in the air. They seemed to have discovered him and wanted to fly over. However, when they were about to leave the passage, they seemed to be blocked by an invisible wall and could not leave the passage.
They were like wild beasts that had seen their prey. They whimpered unwillingly and kept hitting the invisible wall. However, they could not break it.
"As expected!"
Seeing these spirits, Gray was not surprised. Instead, he looked as if he had expected it.
When he had heard the sound earlier, he had already guessed it. Now, he had confirmed it.
Gray had dealt with spirits many times. He had seen abandoned villages full of spirits. He had also seen hundreds of thousands of spirits walking in the night. He had also seen fox beasts that could control spirits.
Gray understood spirits very well. Therefore, after hearing the whimpering sound, he immediately determined that it should be the voice of a spirit.
"I didn't expect the secret room of the castle to be here!"
When he had been touring the castle, Gray had looked for it to see if he could find the secret room of the castle. However, he had found nothing.
He did not expect the secret room of the castle to be in this dry well. If he had not heard the howls of these spirits, he would not have been able to find this secret room for a long time.
"Is some kind of rune mechanism blocking these spirits?"
Gray looked at the entrance of the passage. There was nothing there. There were no walls or barriers. However, the spirits were blocked there, so they could not come out.
Gray couldn't help but be curious. This was the first time he had seen something that could actually block a specter.
He walked over.
Wuwu!
Seeing Gray approach, the spirits roared even more fiercely and kept attacking. However, they were blocked by an invisible barrier and could not rush out of the passage.
Gray pulled out the sword at his waist and tried to stab forward.
With his current strength, he was naturally not afraid of a mere specter. Moreover, he definitely had to explore the secret chamber this time. During the process, he would definitely have to enter this passage. He wanted to see if there was an invisible barrier at the entrance of the passage that sealed the passage.
The sword did not encounter the slightest obstruction. It easily passed through the entrance of the passage and entered the passage. There was no invisible barrier like he had guessed.
Seeing the sword coming in, some spirits pounced on this section of the sword. The cold aura that could freeze people's souls was immediately transmitted to the sword.
However, the sword was a dead object. Naturally, these spirits would not attach themselves to it. These spirits passed through the sword.
The unwilling spirits turned back and danced around the sword.
Crackle!
A trace of thunder and lightning power attached to the sword. A purple thunder and lightning appeared on the sword. For Gray, it could be said that the thunder and lightning was less than 1% of his strength. However, it brought about a destructive power to these spirits.
Just by being sputtered by the thunder and lightning, these spirits screamed and their bodies quickly disintegrated. In the end, more than a dozen spirits dissipated.
After killing all the spirits, Gray reached his hand into the tunnel. His hand easily passed through it. The invisible barrier that could block the spirits could not stop him.
He strode into the room. No matter what, he had to investigate this secret room.
As he walked forward, he saw more than a dozen skeletons. The degree of weathering was different. Obviously, they were people of different times. If Gray guessed correctly, these spirits should be the remains of the owners of these skeletons. This should be a place that could breed spirits.
The tunnel curved downward. It was obviously deep underground. The surrounding walls and floor were all built with a very hard stone. Even Gray could not leave too many traces of damage on this stone.
Gray couldn't help but feel a little expectant. A secret room that could be built with such precious stones would definitely contain extremely precious treasures.
Of course, he could not help but be careful. This secret room could not be lacking in mechanisms. Moreover, the power of these mechanisms would not be small.
Especially the skeletons from before. Gray had checked them. All the skeletons were preserved in perfect condition. There were no wounds left by sharp blades or other attacks. This made him feel a little strange. How did these people die?
Pop!
Suddenly, a strange invisible wave suddenly appeared. It was invisible and intangible, and it was impossible to see or detect. Gray was swept by this invisible wave without noticing it at all.
"Hiss —"
Gray suddenly groaned in pain and pressed his head with his hand.
In that instant, he felt as if he was being pricked by a needle. It was as if his soul was being pulled out like a carrot by an invisible hand.
"What kind of attack is this …?"
Gray sucked in a breath of cold air. With his Barbarian Blood Warrior realm, he was unknowingly hit by this attack. One could imagine how terrifying this attack was.
Now, he finally understood how those people died. Without a doubt, these people were killed by this invisible attack. It was because of this that their skeletons could be preserved in perfect condition. There was not a trace of injury on the skeletons.
Those people were probably the ones who discovered the secret of the well before him. They wanted to explore the secret room and obtain the treasures, but they died silently here.
"Could this be a soul attack?"
It did not harm the physical body, but it made people die suddenly. Moreover, the dead people turned into ghosts. He could not help but suspect that this was a soul attack.
Although he had never seen a soul attack before, he was almost 90% sure that the attack he suffered was a soul attack.
"This secret room might be more dangerous than I thought!"
Gray's expression was grave. A soul attack was almost impossible to guard against. Moreover, the most terrifying thing was that it only targeted the soul. The defense of the physical body was useless. No matter how strong the physical body was, if the soul was too weak, one would immediately die.
Fortunately, he had reached the Barbarian Blood Warrior realm. Under the nourishment of his realm, his soul was definitely stronger than an ordinary person's. This was why he was able to withstand that illusory soul attack.
"I wonder if the fox-type blood fiend that I met last time that could control ghosts knows a similar soul attack?"
He could not help but think of the fox-type blood fiend that he met in the forest that could control souls. He did not know if the fox-type blood fiend with a desolate-level strength had a similar soul attack.
If the fox-type blood fiend had a similar soul attack, then he could be considered extremely lucky. If the fox-type blood fiend had used a soul attack on him, he would have been able to avoid it at that time.
Originally, he had thought of hunting the fox-type blood fiend for a period of time. Although he was only a Barbarian Blood Warrior, his combat strength had reached the desolate-level. He had even killed a Desolate-Level Warrior before. Logically speaking, he should have the strength to kill the fox-type blood fiend.
But now that he thought about it, he felt that it was too risky. If the fox-type blood fiend had a similar soul attack ability, his strong physical defense would not be of any use. After all, it was an attack that targeted the soul.
"Should I continue?"
Gray's expression was grave. The danger of this secret room had exceeded his expectations. He had only ventured deeper and there were already such dangerous rune mechanisms. If he continued to venture deeper, would there be even more dangerous mechanisms?
"Could this castle really be a building from the Empire Era?"
Such a dangerous mechanism, even compared to the last mechanism in the King's Graveyard, would not be inferior.
He could not help but suspect that this building was from the Empire Era that was even more glorious than this one. Moreover, the identity of the owner was probably not simple. Even if it was during the Empire Era, the person who could build such a secret room was definitely not a simple person.
"Let's explore further. If it doesn't work, I will immediately retreat!"
Gritting his teeth, Gray decided to move forward a little more.
Although the formless soul attack was dangerous and impossible to defend against, with his Barbarian Blood Warrior realm, he should be able to withstand it.
Bo — —
Gray advanced cautiously. Every step he took was especially careful. After advancing for more than ten meters, suddenly, another formless wave swept towards Gray. Gray could not help but clutch his head in pain.
After standing still for a moment, Gray recovered and continued forward.
Bo, Bo, Bo!
After advancing for more than twenty meters, he encountered another formless soul attack.
After advancing for more than ten meters, he encountered another formless soul attack.
After advancing for more than thirty meters, he encountered another formless soul attack.
Gray had already suffered four formless soul attacks. The intense pain caused cold sweat to seep out of his forehead. He was a little hesitant as to whether he should continue forward.
"Hmm, ahead?"
After turning a corner, he suddenly discovered that it was no longer an empty tunnel. Instead, it was a room with a stone platform and other furnishings. Obviously, he was about to reach the secret room.
The secret room was right in front of him. No matter what, he could not give up at this time. He gritted his teeth and continued forward.
