The secret passage is between a mountain wall. When the moon rises from the valley, the moonlight shines on the mountain wall and appears to have a clear bright silver color. The stone wall is composed of rough limestone. The surface is covered with cracks and uneven patterns due to the erosion of time, like the wrinkled skin of a giant.

The silver-gray giant guards the secret of silence. The extremely lush moss and vines growing on the stone walls are its thick hair. Several thick vines hang from the top of the mountain, hiding an inconspicuous entrance. The entrance is hidden under a huge rock. The branches of the vines are covered with small thorns, like a natural barrier.

Fang Zhu took out his knife to cut the rattans, and the Paparals crawled in reluctantly. He complained, "Be careful, I don't know if that guy can recognize me."

A few minutes ago, he called the displacement beast "Fat Cat".

But since he entered this valley, he changed his name to "Big Cat", and after a while he became "that big guy".

Everyone was accustomed to it, and they bent down one by one. Only Fang Yu turned around and said to the princess: "Miss Lian, why don't you and Miss Merell stay here?"

He really couldn't think of what it would be like to take an elf princess into a mountain lord's castle, but the elf girl took the initiative to come.

"So Mr. Ed still cares about my identity," Lian replied in a gentle tone, "but it is this level of identity that is why I asked to join. I have seen Aina Xiaoyu once. If something goes wrong, I can guarantee you with my own identity."

"And, is Mr. Ed planning to keep Merriel and me here? Or is he going to leave someone to take care of us?"

Fang Yu was speechless and had to let the princess be careful and stay with Silvede all the time.

Merell looked at him and His Highness and looked down at him and followed him with some admiration.

Fang Zhu stroked the vines above her head so that the thorny branches would not entangle the elf girl's hair. He sighed at the two brave unicorn girls.

In fact, Merriel didn't know why she was here. This adventure seemed to have nothing to do with her, but she had nowhere to go.

Returning to Silver Wind Harbor is already a luxury, and it will only bring danger to Fni and Ai Luoya, but she can't do much when she stays here. Her ability is meager, and she can't compare to that princess.

But neither the Princess nor the leader asked her to leave, which made her feel a little embarrassed.

She was neither a member of the investigation team like Marian and Bachelor Arian, nor a confidant of His Royal Highness the Princess, nor a member of the Seven Seas Brigade.

Fortunately, Ai Luoya was still with her, which made her feel a little more at ease.

After entering the cave, there was a dark and rugged road, as if the sound of footsteps echoed among the stone walls, the air was becoming more dull and cold, and each step seemed to be deeper into the increasingly unknown darkness.

However, Fang Zhu, Jita, and Silweid were all used to such an environment, and the Elf Princess also performed well, only Merriel was a little uneasy.

She was holding her willow wood holy emblem with her hands, and using her faith to dispel everything.

Suddenly, the road ahead became wider and a man-made staircase appeared before them.

And just as the Paparals stepped on the ladder, a pair of golden eyes appeared in the darkness above the steps.

The pair of eyes flashed with a cold and sharp light, like two gems embedded in the dark curtain, staring at them from a high point, with scrutiny and alertness in their eyes.

This scene scared Jita, and the naturalist Miss instinctively took a step back and hit Fang Zhu's shoulder.

Fang Yu stabilized her, gently held her shoulder, signaling her not to be afraid. He raised his head and recognized the master of the eyes.

That was the guardian of the Aina Xiaoyu family. The tall displacement beast was like a strong black panther. It appeared silently like a ghost, and its silver-blue hair shone with glimmer in the darkness, like the twinkling stars in the night sky.

The displacement beast leaped gently and landed on the stairs in front of them. It seemed to recognize the Paparals in front, restrained the hostility in its eyes, and only trembled its ears slightly, but still looked at the others with obvious vigilance.

"Big guy, it's me," the Paparals purred, "Don't worry, they are not malice."

The other party looked at Fang Rong and others in a doubt, and responded with an equally low and gentle grunt.

But it immediately turned around, revealing a long tail, jumped vigorously to the several steps above, and then looked back at them, and their figures soon disappeared.

"It keeps us up." Parker looked at the others and replied.

If Tianlan were here, it would be a big surprise. Fang Zhu didn't expect that Parker was so familiar with this displacement beast - he would even communicate with the other party.

He couldn't help but wonder how many times did this guy come to this castle? This guy wasn't a habitual thief, right? So they brought a habitual thief to the victim's house to "explor". No wonder Parker acted so resistant.

He didn't dare to think how warm the welcome would be from the owner of the castle if they were accidentally discovered.

Fang Yu couldn't help but start to doubt the rationality of his decision, but the idea disappeared without a trace in an instant. They followed the guardians of the Aina Xiaoyu family to the ladder, but not long after that, the big cat disappeared without a trace.

The Paparals are not surprised by this. The displacement beast god is elusive. Sometimes the "fat cat" is not hungry and is unhappy to go to the castle with him.

"It just put us in?" Merriel was a little surprised.

With the serious personality of the elf girl, it is really hard to accept that the guardians of the Aina Xiaoyu family are just dereliction of duty.

She couldn't help but start to worry about the unguarded back door of the Aina Xiaoyu family, although that had nothing to do with them at all.

The elf princess was also a little puzzled and couldn't help but look at Fang Zhu.

But seeing Parker's unwillingness to answer, Fang Yu only means that the other party is an exception, and the displacement beast is very alert to them.

He vaguely felt that there was something else that the Paparals had not spoken to them, but after thinking about it, it seemed that it was indeed not a glorious thing.

But it's all in the past. If they have the chance, they can actually talk to the mountain lord about compensation.

If the other party is not involved in this case.

Fang Yu thought of the dagger again - he started to have a headache. He is not short of this mitral now, but the symbolic meaning of that dagger seems to be greater.

The stone steps extend upwards, with some wear on the edges. From time to time, an iron lamp holder is inserted on both sides, with perpetual burning crystals inserted, emitting a dark light.

This stone staircase leads to the underground and warehouse of the castle, separated by a stone door. The stone door naturally cannot stop the displacement beast, nor can it stop a Paparal man.

Parker pulled a switch on the side of the stone door with a quick look, allowing the stone door to slowly move to the side, and a lot of dust fell on it, making him unable to help coughing:

"Since I left, no one has been here for a long time."

Everyone else looked at the Paparal people with a weird look—the feeling that the other party didn't seem to be coming to sneak into the castle, but it was more like going home in a long time.

Even Lian couldn't help but look at Fang Ling again. Although it was not that the upright people must be surrounded by upright people, she actually... it's not that she can't understand the profession of Nightingale.

However, it is still difficult to accept the fact that he regards other people's residences as his own home, due to the education that His Highness has always received.

"Well, Parker hasn't done anything like this since he joined us."

Fang Yu coughed lightly and explained awkwardly.

He was a little unacceptable to such things. Although they had never done stealing things, at least their opponents could be said to be not kind.

Lian nodded, not questioning anything.

The Paparals did not hear the conversation behind them, but only reminded, "Be careful, there are guards in the castle, and I don't know if their patrol plan has changed for so long."

He walked in one direction, but Silmide, who had not spoken, called him, "Wait, Parker, in that direction?"

"What, the kitchen."

Amid the stern gaze of the ship's officer, the Paparal slapped his forehead, "Oh, sorry - I'm used to it."

"Where should we go?" At this time, the elf princess also realized the problem and asked Fang Zhuo on the side.

Fang Yu closed his eyes silently, and he quickly confirmed that the Holy White Tree Heart is in this castle, but it is still difficult for him to judge the specific location.

It was about the top of their heads, in a room southwest.

He pointed out this and everyone was excited, but their faces quickly became serious again, which showed that Lord Shan was really related to the mastermind behind the scenes.

At least one or even two of them.

As for the position that Fang Ling pointed out, naturally, he could only wait for a certain "King of Nightingale" to answer, and everyone once again turned their attention to Parker.

The latter thought for a while before answering: "That place seems to be the study of the castle, but it is very close to the guest rooms."

"Will Aina Xiaoyu use that study?" Fang Yu asked.

"No, she doesn't usually go there," the Paparals shook their heads, "the owner of the castle has his own room and study."

"That at least means that it is very likely that there is little to do with her." Fang Yu breathed a sigh of relief. Now the suspects are more suspected to have come to Wat Shiqiu, but it is not necessarily because the servants in the castle may also use that room.

But he was a little curious, "How come you even know this?"

"Damn it, why do you have so many questions? If you are not satisfied, go and ask others," Parker said a little unhappy.

He urged again: "Hurry up, I don't want to be caught."

Fang Yu naturally didn't want to. He put his hand on his information crystal and then projected several walkers.

The clockwork fairy vibrates its wings when flying, and it makes a sound, which is too easy to be discovered in the enclosed space, so he bought these walkers.

He upgraded these low-level components with gray branches and finally got a design called "hidden".

Because it is almost the lowest-level component except for the clockwork fairy, he modified it after only a whole afternoon.

These hidden people have simple optical disguise ability, just like the ability to march silently. Of course, they are as hiding without any hiding under magic detection, but it is enough to use it in such a scenario.

Apart from the protection of the fan lock, no one will impose magic on his entire castle. As long as they do not enter some core areas, they are 100% safe.

Fang Yu originally wanted to use them to determine the other party's guard and patrol routes.

He found that using gray branches as material to transform the structure can easily obtain abilities related to hiding, which both 'snake pupils' and 'snakes' proved.

There are only a slight exception to the Gujun Guard, but the Gujun Guard is a secondary upgrade on the King's Ultimate Jade, which is a bit different.

He released these hiding men and soon found a small number of guards. The Paparals lived a comfortable life and the protection of the castle was not tight.

Besides, with Parker, the "insider", they easily avoided those areas and came to the upper floor of the castle and entered a hall.

According to the Paparal people, this hall is remote and there are usually no servants to come to this place. Through its stairs, you can lead to the corridor on the third floor—

From that place, they can easily reach the guest room area.

But they had just entered the hall, and the crystal lamps around them suddenly shone brightly. The sudden bright light in the dark made everyone unable to help but squint their eyes.
