Ning Du answered, didn't say anything more, turned around and led the way in front.

The three of them walked out of the side hall and walked into the depths of the main hall.

In the middle of the main hall is a shelf dedicated to tablets.

Ruan Jiujiu looked at it while walking and found a strange thing.

"There are so few tablets here, is the history of the North Vietnamese royal family very short?"

Bei Mingxuan said: "No, maybe the tablets are scattered." ”

Ruan Jiujiu sighed, and didn't ask any more, but Bei Mingxuan suddenly said: "Tiansheng's Taimiao seems to be like this." ”

"It's the same with Tiansheng, there aren't many tablets in the main hall?" Ruan Jiujiu asked in surprise.

Bei Mingxuan nodded, and Ruan Jiujiu said: "That's really strange, Beiyue and Tiansheng actually have the same Taimiao, is this a coincidence?"

"Probably not. "The Northern Mystery Road.

Ruan Jiujiu felt a little weird more and more.

Speaking of which, Bei Mingxuan is the prince of Tiansheng, although he was not born to the first emperor of Tiansheng, but he also grew up in Tiansheng since he was a child, but on the contrary, he also has the identity of the son of Ninghou of Beiyue. This identity also existed from his birth, he knew about it, and he knew that there was a secret during this period, but he didn't know why.

It's so weird! It's so unsettling!

Looking at the pattern of this Taimiao now, it is similar to Tiansheng's, Ruan Jiujiu faintly feels that there is a connection between this.

She could think of it, and Bei Mingxuan should be able to think of it, and she couldn't help but look at him worriedly.

At this time, Bei Mingxuan was still wearing a mask, and she couldn't see his expression clearly, but she saw that his eyes were gloomy.

Ruan Jiujiu's heart suddenly softened and approached him.

When she approached, Bei Mingxuan was not polite, and pulled her to her side.

Ruan Jiujiu felt that he was sick with a soft heart!

This man has a chance not to let her go.

Ning Duan was in front, and he didn't notice what was going on, he stopped, turned around and said, "Lord and Princess, the organ is here." ”

Ruan Jiujiu looked and found that they had already walked to the innermost part of the main hall, behind the tablet shelf, if they hadn't come here, they wouldn't have found that there was still a large open space here.

In this kind of place, no one usually comes here, so if the mechanism is set up here, it should be quite safe.

Bei Mingxuan glanced at Ning Dui.

Ning Duan said: "Lord and Princess, the mechanism here is quite cleverly set up, but I have already seen them open it just now. ”

"Then you open it. Ruan Jiujiu said.

Ning Dui arched his hand and said, "Yes." ”

He stepped aside, then tapped twice on a wall.

Ruan Jiujiu looked over and found that the wall was very smooth and smooth, so she was very suspicious that the mechanism would be set up there.

After two taps there, Ning Du walked to the opposite side, knocked twice on the equally smooth wall where nothing could be seen, and finally, he walked to the middle again, crouched down, and then knocked three times on the ground.

Ruan Jiujiu glanced at Bei Mingxuan suspiciously, and Bei Mingxuan's eyes were calm.

At this time, Ning Du got up and said, "Okay." ”

"Okay?" Ruan Jiujiu found that there was nothing unusual here.

Bei Mingxuan said, "Let's go." ”

"Where are you going?" Ruan Jiujiu just asked, and was pulled forward by him.

Ruan Jiujiu was even more suspicious, because the direction in which Bei Mingxuan was pulling her was a wall, and because this was the depths of the main hall, and there were tablet shelves blocking it, the wall in front of it looked very dark.

It's not going to be through the wall, is it?

She was about to ask, but found that she had really passed through the wall.

"It's not a wall, it's just a fake image created by light and tricks. Bei Mingxuan explained.

Ruan Jiujiu was stunned, and said for a long time: "It's so ingenious." ”

Ning Du also said on the side: "Yes, my subordinates were also stunned when they saw it at first. The switch of this mechanism is silent even if it is opened, and we can see the changes with our eyes, and we think that the walls are still there, so even if we know how to open them, we will be deceived by our own eyes. ”

Ruan Jiujiu nodded, only feeling very divine.

"Where are we going now?"

At this time, Ruan Jiujiu found that she had walked into a dark passage, where there was light, but she couldn't tell where it came from, and it wasn't too bright.

Ning Duan said: "This is a dark passage, and my subordinates have only followed this secret passage before, only knowing that there is a big dark palace in front of me, and the others are not very clear." ”

Ruan Jiujiu nodded, his mind tightened a little.

Bei Mingxuan held her hand, as if sensing her emotions, and the strength of his hand increased.

The three of them walked slowly, and after walking for about a pillar of incense, they found that the light in front of them had become brighter.

"Lord and Princess, it's here. ”

Ruan Jiujiu glanced at Bei Mingxuan, who was also looking at her, he nodded slightly to her and said, "It's okay, let's go." ”

Ruan Jiujiu also said to him: "It's okay. ”

Bei Mingxuan knew that she was blindly worried about herself, so she smiled helplessly, took her hand and continued to walk forward.

They walked out of the dark passage and found that they had entered a large hall, which was very large, about the same arrangement as the floor, except that it looked like no one had been here for a long time, and there was dust everywhere.

Ruan Jiujiu looked at it and said in a low voice, "There is no one here." ”

Ning Duan said: "They are in the side hall over there, and there is a side hall there. ”

Bei Mingxuan said: "Ning Dusk, be careful. ”

"Yes, the princess and princess should be careful. After Ning Du finished speaking, his body was raised, and the figure flickered, and the figure disappeared.

"We're going over there too. ”

Bei Mingxuan said and came over and grabbed Ruan Jiujiu, got up and swept away, and swept forward with her.

Ruan Jiujiu once again felt that it was really trouble-free to do light work.

This dark palace is really the same as a normal palace on the ground, there are beams and pillars on the top of the palace, and Bei Mingxuan jumped a beam with Ruan Jiujiu.

The two sat down and looked down.

In the side hall, there were four people standing, and in front of them there was another person, who was holding a box in his hand.

"Is that something you got from the deserted city?" Ruan Jiujiu asked in a low voice.

Bei Mingxuan said: "It should be." ”

Ruan Jiujiu was okay, and stretched his neck to go and see.

Bei Mingxuan hugged her and said, "Don't worry, they can't open this thing now, no matter how hard you try, you won't be able to see it." ”

When Ruan Jiujiu heard this, he was immediately a little disappointed.

"What are they doing?"

Bei Mingxuan said: "Probably waiting for someone." ”

Ruan Jiujiu was stunned for a moment, and asked again, when he heard footsteps, more than one person.

Her heart tightened, and she saw two people walking from the opposite direction.

What Ruan Jiujiu also saw before in that direction was also a wall.

It seems that there are more than one place here with the kind of subtle mechanism outside.

When the two got closer, Ruan Jiujiu was taken aback when he saw them clearly.

"It's the Emperor and the Empress!"

The person who came was the Emperor of Beiyue, and the two came side by side, although they couldn't see the expressions on their faces clearly, but they could see that they were in a hurry, obviously very anxious.

Bei Mingxuan nodded, and his eyes were also fixed on him.

Ruan Jiujiu felt that Bei Mingxuan's mood seemed to be a little nervous, so he took the initiative to reach out and hold his hand.

The emperor and empress came over, and the five men hurriedly knelt down and saluted.

"Slaves see the Queen. ”

"Get up. Liu Yi, is this something?" the emperor raised his hand, looked at the box in the hand of the person in front of him, and couldn't help but feel a little excited.

Liu Yiyi: "Exactly, the queen, please see." ”

The Emperor and Empress hurried over, both nervously looking at the box.

Liu Yiyi: "Emperor, this box is locked, but there is no key, and the slave was found in a secret compartment in the ancestral house of Ning Hou Mansion." ”

The emperor's voice trembled a little, and he reached out to take the box, and said, "That's right, if you found it in the ancestral mansion of Ninghou Mansion, it should be that thing." It's been so many years, and I've finally found it, it's great!"

The queen also said: "If you get the things inside, the emperor won't have to keep it in the future." ”

The emperor said: "It's not important, what matters is what's inside." ”

The queen also nodded, just looked at the box carefully and said: "Emperor, the material of this box is very special, and the bottom is tightly seamless, and you can't see it with chain eyes, how can you open it?"

The emperor smiled coldly and said, "I didn't know before, but I recently read that the codex left by my father said that it was not necessary to open this box with any keys and keyholes. ”

"What does this mean?" said the queen, who also knew about the box, but not about it.

The emperor said: "I also just saw that codex, the key is in this dark palace, do you remember that there is a very special place in this dark palace, right?"

The queen nodded and said, "I know, it's that shelf." ”

The queen reached out and pointed to one place.

Sitting on the beam, Ruan Jiujiu and Bei Mingxuan looked in the direction the queen pointed.

They saw that in the side hall, there was a shelf, which looked quite special, and they couldn't see any use at all.

The Emperor held the box and walked towards the shelf, and the Empress followed him.

Ruan Jiujiu and Bei Mingxuan's gaze also followed the emperor's movements.

The Emperor walked to the shelf, looked at it carefully, and then suddenly smiled strangely, and reached out to put the box in his hand to the shelf.

Only then did Ruan Jiujiu and Bei Mingxuan see clearly that there was a lattice on the shelf, and the size was just enough to fit into a box.

"I never knew what this frame was for, when my father died, he told me that this thing was very important, and said that I would understand when I found something in the future, I never understood what my father meant, but now I finally understand. The emperor looked at the lattice that could just fit into the box, and said excitedly.

The queen also said: "Then the emperor should put it away, maybe as soon as he puts it away, the box can be opened." ”

The emperor nodded, and as soon as he let go of his hands, he could only "bang", and the box fell into that grid.

Sure enough, it was just right.
