She could tell that Xue'er wasn't a bad woman. Not only was she kind, but she also loved Yuchi Xuan. However, a man like Yuchi Xuan, who possessed both status and looks, and who possessed both moral character, could easily win the heart of a woman.

Yun Ruo Lu and Yuchi Xuan circled the eight pillars, but still didn't discover anything major. Yun Ruo Lu guessed that if they wanted to enter the underground palace, they would be lacking something, something equivalent to a key to the entrance of the underground palace.

At this moment, Xue'er hesitantly took out a blue night pearl from her sleeve and handed it over to Yuchi Xuan. "Try this! This is what my father left me when he was still alive. He said that this is our family heirloom and that I must take good care of it. "

Yuchi Xuan gave Snowy a complicated look. No one could tell what he was thinking.

Seeing that Xue'er handed over the pearl, Yun Ruo Lu knew that her guess was correct, and that they should be able to open the door to the underground palace soon.

"Let me do it!"

Yun Ruo walked over and took the pearl from Yuchi Xuan's hand, then carefully placed it into the lion head's mouth.

The bead immediately shattered into powder when it heard a bang. Two blue lights burst out from the lion's eyes. The ground suddenly shook. Everyone who was standing on the stone slab could feel that the stone slab was sinking!

Before anyone could dodge, they heard the sound of sand sliding down from the surrounding as it came flooding in. In just a few moments, they had fallen into the sand.

Fortunately, there was a lot of sand on the ground, so no one was injured when they fell. Yuchi Xuan blew the candle flame, illuminating the darkness.

Beneath the desert, there was indeed a stone room that was similar to a palace. This stone room was very large, and each of the four walls had a door on them. Each door was connected to a different passage. It was as if a terrifying mechanism was hidden within, and they had to find the right path by themselves.

The biggest problem they were facing right now was not knowing where to go.

"Why don't we split up and move out? Whoever finds the main tomb first will think of a way to inform everyone."

Yuchi Xuan was still lost in thought, while Yun Ruo Long refused.

"No, this is too dangerous. It would be best for all of us to go together. If we split up, we might never be able to find them again."

Many of the books she had read last night had mentioned that if she came back, she would not be able to find her way back.

As Yun Ruo Lu said this, she tried opening a door casually. There was a long corridor inside. Yun Ruo You stood outside the door and threw a stone into the corridor. Nothing strange happened before she brought her people inside.

The corridor was very narrow, allowing only one person to pass through. Yun Ruo Lu walked at the front, with Yuchi Xuan following behind her, followed by Snow, and then the rest of the soldiers who had fallen in.

The stone walls on both sides of the corridor were very smooth, as smooth as if they had been oiled. It was ice-cold to the touch, and the cold could even be felt from the tips of one's fingers into one's bones.

Although there were more than 20 people in this line, the corridor still gave off a creepy feeling.

After about five minutes of walking, the corridor gradually became wider, and they could even walk in two parallel paths.

However, this corridor seemed to have no end. The further one walked, the more uncertain they became.

In the next hour, Yun Ruo Lu and her group felt as if they were walking through a maze. They turned and turned several times, but they were already trapped in the corridor and were unable to find the exit.

At this moment, Yun Ruo Lu guessed that they had probably walked into the wrong place. If they were just getting lost like this, it would be alright. But if they encountered some traps, they wouldn't even have a place to hide in this narrow corridor.

"We have to think of a way to leave this place first!"

Everyone knew that they had chosen the wrong path, but they had already entered. No matter what they said, it was useless. They could only think of a way to leave as soon as possible.

"We seem to be trapped. Everyone, be careful."

Yun Ruo Lu continued to walk as she spoke. She didn't understand why they didn't meet any crossroads and couldn't get out. Even if this corridor was a dead end, they should still be able to walk back to the entrance.

"Why don't we go back!"

Yun Ruo Lu stopped walking, thought for a while and said, "Let's try to go back first, see if we can make it to the entrance!"

As they came in rather suddenly, they didn't bring any food with them. If they continued to stay in the underground palace like this, they would starve to death in a few days.

Therefore, although the treasure was important, the prerequisite was that they had to leave this place alive.

The group continued to walk back, but in the end, they were left absolutely terrified. After walking for two hours, they still hadn't found the entrance that they had come in from!

This not only caused the accompanying soldiers to panic, but even Yuchi Xuan began to feel uneasy.

Yun Ruo Man had been wondering where the problem was. There was clearly only one path, but they could actually get lost in this path.

"No, I can't walk anymore. Let's rest for a while." she said, holding on to the wall.

After walking for more than four hours, everyone was tired. However, they all wanted to leave this place as soon as possible, so no one suggested taking a break.

"Everyone, let's rest for a while. I don't think we'll be able to get out in a short period of time."

Yun Ruo Lu also stopped to rest, while the other imperial guards started to discuss softly.

"You said that we won't die here, right?"

The voice of one of the guards was very soft, and only the other person beside him could hear it. However, Yun Ruo You knew how to speak, and could naturally see what they were saying.

"Don't talk nonsense. Even if you die, isn't the king here? With Prince here, what are you afraid of? "

Yun Ruo Lu felt a bit guilty, but at the same time, she could tell that these soldiers were extremely loyal to Yuchi Xuan.

Yuchi Xuan was resting against the wall. He didn't say anything, nor did he blame Yun Ruo. He just sat there quietly, thinking about his own matters.

Yun Ruo You wanted to go over and comfort Yuchi Xuan, but just as she took a step, her foot slipped and she almost fell to the ground.

"Are you okay?"

Seeing that Yun Ruo Lu was acting strange, Xue'er hurriedly went over to support her and asked in concern, "What's wrong?"

"I don't know either. It seems like I stepped on something."

As Yun Ruo Lu spoke, she squatted down and used her hand to feel the area she stepped on just now. She discovered that the ground was covered by a thin layer of water that was like a mist.

Yun Ruo Lu suddenly realized something. She touched the wall and discovered that there was a layer of water vapor on the wall as well. It was very thin, so thin that it was hard to find.

Perhaps no one knew how the water vapor was formed, but Yun Ruo Lu knew very well that it was because they needed to breathe as they walked in the corridor, and the water vapor was formed when they breathed.

The unremarkable water vapor might have been the key to getting them lost.

The ground had become smoother than before, and if this wall had a millimetre of activity, it would have caused a huge error, causing the road they were walking on to deviate far from the road they came from.

"What is it? Did you find anything? "

Seeing Yun Ruo Man staring at the wall in a daze, Xue'er curiously asked.

"Hmm, I think I've found a way to get out of here!"

When Yun Ruo's words came out, everyone turned to look at her. Everyone's eyes were filled with hope, hoping that Yun Ruo Lu would really be able to bring them away from this place.

"What method?"

Hearing that Yun Ruo Lu had a solution, Yuchi Xuan came back to his senses and asked her.

"I don't know if it's feasible or not, but we can give it a try!" Everyone pressed their backs against the wall and covered their mouths and noses with cloths. Let's go and see if we can get out! " Walk against the wall, you can wipe away the moisture on the wall, and cover your mouth and nose with a cloth to prevent new water from coming out and sticking to the wall.

The corridor inside was relatively cold, so once the water vapor stuck to the wall, it would not disappear easily. It would even converge into water current that flowed to the bottom of the wall, causing the wall to move.

However, these were just her conjectures. She had to try to find out whether this plan was feasible or not.

Everyone did as Yun Ruo Man said, covering their mouths and noses with their sleeves.

With their backs against the wall, they walked forward. Although their speed was much slower than before, they only walked for ten minutes before reaching the entrance.

"Look!" There's a door! We've found the exit! "

A soldier shouted excitedly when he saw the door not far in front of him, giving the soldiers behind him a lot of confidence.

After spending nearly six hours in the corridor, everyone collapsed on the ground and let out a huge sigh of relief, looking as if they still had some lingering fear in their hearts.

Although the wrong path this time was a surprise, it was not dangerous. However, if they were to continue searching for the treasure, Yun Ruo Lu did not dare to randomly choose another path.

If her mistake caused everyone to lose their lives here, even if she died, she would still feel guilty.

Xue'er had been silent ever since she came out, but there was a tinge of sadness in her eyes.

Yun Ruo could understand her feelings, if it was her, she wouldn't want to personally bring people to dig up her ancestral tomb. Moreover, filial piety was the first thing in the ancient times. This was really making things difficult for her.

But at the same time, it could be seen how much love Snowy had for Yuchi Xuan. He just didn't know what attitude Yuchi Xuan had towards this.

As she thought about it, Yun Ruo Lu felt her thoughts drift further and further away. Yuchi Xuan was the Third Marquis, but he only had two concubines; he had never taken a wife.

He didn't know what secrets were hidden behind such a strange occurrence.

After resting for roughly half an hour, Yuchi Xuanyuan had everyone gather their energy and continue searching.

This time, Xue'er took the initiative to ask her to make her own choice. Yun Ruo Lu did not have any objections, after all, she was still a rookie regarding the matter of robbing tombs.

Seeing that Xue'er seemed very confident, Yun Ruo guessed in her heart that Xue'er might not be able to say anything.

After all, this tomb belonged to Xue'er. Only Xue'er knew what had been left behind by their ancestors.

Xue Er stood in the stone room and walked around in a circle before finally choosing the door to the left of the door Yun Ruo Lu had chosen earlier.
