Ning Mu responded without saying anything, turning around to lead the way.

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

In the middle of the hall, there is a shelf for memorial tablets.

Ruan Jiujiu walked and looked at it, and found a strange thing.

"There are so few tablets here. Is the history of the North Vietnamese royal family short?"

Bei Ming Xuandao: "No, maybe the tablets are scattered."

Ruan Jiujiu said, without asking any more, Bei Mingxuan suddenly said, "Tiansheng's Taimiao seems to be like this too."

"The same is true for Tiansheng? There are not 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?"

"Perhaps not." Bei Ming Xuandao.

Ruan Jiujiu felt a little weird.

Speaking of Bei Mingxuan is the prince of Tiansheng, although he is not the first emperor Tiansheng, but he also grew up in Tiansheng, but unfortunately, he still has the identity of the son of Ninghou in North Vietnam. This identity has existed since he was born. He knew about it and knew there was a secret during this period, but he didn't know the reason.

This is really weird! It's so disturbing!

Looking at the layout of the Taimiao, it is similar to that of Tiansheng, Ruan Jiujiu faintly felt that there was any connection between these.

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

At this time, Bei Mingxuan was still wearing a mask, she could not see his expression, but she saw his eyes faint.

Ruan Jiujiu suddenly felt weak and approached him.

She approached, Bei Mingxuan was not polite, and pulled her to his side.

Ruan Jiujiu felt that he was sick because of his soft heart!

The man would not let her go if he had a chance.

Ning Mu was in front, but he didn't notice what was going on behind him. He stopped and turned around and said, "Prince and Concubine, the agency is here."

Ruan Jiujiu looked and found that they had already reached the innermost part of the main hall, behind the tablet shelf. If they hadn't come here, they wouldn't find that there was still a large area of ​​open space.

In such a place, generally no one will come here, so if the agency is set up here, it should be quite safe.

Bei Mingxuan glanced at Ning Mu.

Ning Mu said: "The prince and concubine, the mechanism here is quite clever, but I have seen them open it just now."

"Then you open it." Ruan Jiujiu said.

Ning Mu arched his hands and said, "Yes."

He stepped aside, then tapped twice on a wall.

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

After Ning Mu tapped twice there, he walked to the opposite side and tapped twice on the same smooth wall with nothing to see. Finally, he walked to the middle again, squatted down, and then tapped three times on the ground. .

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

At this moment Ning Mu got up and said, "Okay."

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

Bei Mingxuan said, "Let's go."

"Where are you going?" Ruan Jiujiu just asked, and he was dragged forward.

Ruan Jiujiu was even more suspicious, because the direction Bei Mingxuan took her was a wall, and because it was the depths of the hall, and there was a tablet shelf blocking it, the wall in front looked very dark.

Isn't it about going through the wall?

She was about to ask when she realized that she had really passed through the wall.

"This is not a wall, it's just a illusion created by using light and mechanical techniques." Bei Mingxuan explained.

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

Ning Mu also said on the side: "Yes, what the subordinates saw at first was shocked. Even if the switch of this mechanism is turned on, it is silent, and we can see no change in our eyes, thinking that the wall It's still there, so even if you know how to open it, you will be fooled by your own eyes."

Ruan Jiujiu nodded, just thinking it was amazing.

"Where are we going now?"

At this time, Ruan Jiujiu discovered that she had already walked into a dark tunnel. There was light here, but she couldn't tell where it came from, and it was not too bright.

Ning Mu said: "This is an underpass. The subordinates only followed this underpass before, only knowing that the front is a big dark palace, and the others are not very clear."

Ruan Jiujiu nodded, his mind tightened.

Bei Mingxuan shook her hand, and also seemed to sense her emotions, and the strength in her hand increased.

The three of them walked slowly, walking for about a stick of incense, only to find that the light in front of them became brighter.

"Prince and Princess, here it is."

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

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

Knowing that she was worrying about herself, Bei Mingxuan smiled helplessly, took her hand and continued walking forward.

They walked out of the secret tunnel and found that they had entered a large hall, which was very large and arranged like the ground, but it seemed that no one had been here for a long time, and there was dust everywhere.

Ruan Jiujiu looked at it and whispered: "No one here."

Ning Mu said, "They are in the side hall over there, and there is another side hall there."

Bei Mingxuan said: "Ning Mu, be careful."

"Yes, the prince and princess are also careful." Ning Mu finished speaking, and the figure disappeared when he lifted his body.

"Let's go there too."

Bei Mingxuan came over and embraced Ruan Jiujiu, got up and swept, and led her to the front.

Ruan Jiujiu felt again that light work is really easy.

This dark palace is really the same as a normal palace on the ground. There are beams on the top of the palace, and Bei Mingxuan took Ruan Jiujiu onto a beam.

The two sat on it and looked down.

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

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

Bei Ming Xuandao: "It should be."

Ruan Jiujiu became curious, and craned his neck to see.

Bei Mingxuan grabbed 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 a little disappointed.

"What are they doing?"

Bei Ming Xuandao: "Probably is waiting for someone."

Waiting for someone? Ruan Jiujiu was taken aback and asked again, when he heard footsteps coming from more than one person.

As soon as she felt nervous, she saw two people walking in the opposite direction.

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

It seems that there is more than one exquisite mechanism like that outside.

When the two got closer, Ruan Jiujiu saw them clearly and was taken aback again.

"It's the emperor and queen!"

The visitor was the Empress Beiyue, and the two came side by side. Although they could not see the expressions on their faces, they could tell that they were in a hurry, obviously very anxious.

Bei Mingxuan nodded, and stared closely at the past.

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

When the emperor and queen came over, the five people hurriedly knelt and bowed.

"Minions see the Empress and Queen."

"Get up. Liu Yi, is this the thing?" The emperor raised his hand and looked at the box in the man's hand in front of him. He couldn't help but get a little excited.

Liu Yi said: "Exactly, please see the emperor and queen."

The emperor and empress walked over quickly and looked at the box nervously.

Liu Yi said: "The emperor, this box is locked, but there is no key. The slave was found in a secret area in the ancestral house of Ninghou Mansion."

The emperor's voice trembled a little, and he reached out to take the box, and said, "Yes, if it was found in the ancestral house of Ninghou Mansion, it should be that thing. After so many years, I finally found it by me, great! "

The queen also said: "If you get the contents inside, the emperor won't have to keep Ninghou anymore."

The emperor said: "This is not important, what is important is what is inside."

The queen also nodded, but just looked at the box carefully and said: "Your Majesty, the material of this box is very peculiar. The upper and lower parts are tightly stitched. You can't see the interlocking eyes. How to open it?"

The emperor smiled coldly and said: "I didn't know before, but I recently read the handwritten note left by the emperor father, saying that to open this box, you don't need any key or keyhole."

"What does this mean?" The queen wondered. She also knew about this box, but she didn't know it.

The emperor said: "I also just saw the codex. The key is that it is in this dark palace. Do you remember that there is a very strange place in this dark palace?"

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

The queen stretched out her hand and pointed.

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

They saw that in the side hall, there was a shelf, which looked strange, and could not see its use at all.

The emperor held the box and walked towards the shelf, and the queen followed him.

The eyes of Ruan Jiujiu and Bei Mingxuan also followed the emperor's movements.

The emperor walked to the front of the shelf, took a closer look, then suddenly smiled weirdly, and then reached out and put the box on the shelf.

Only then did Ruan Jiujiu and Bei Mingxuan see clearly that there was a grid on the shelf, the size of which was just right to fit a box.

"I never knew what this shelf was for. When my father died, I told me that this thing was very important. I said that I would understand when I found something. I never understood what my father meant. Now I finally I understand." The emperor said with excitement looking at the grid that just fits into the box.

The queen also said: "The emperor will put it up soon, maybe the box will be opened as soon as it is put up."

The emperor nodded, his hands were loosened, and the box fell into the grid with a "clang".

Sure enough, it was just right.
