The cave was rugged, and there was hardly any light that could shine in, so Liu Xuan had to use a spiral light to illuminate it.

This trick was originally used to burn the skills of enemy soldiers close to him in the chaotic army, but it was used by Liu Xuan like this, and everyone didn't know what it was, but Qin Yilu and Diao Chan knew this trick, and when they saw the emperor actually use it like this, they were speechless for a while.

However, Shi Daoren didn't know the key, looked at the three 'lights' floating beside Liu Xuan, and praised: "This spell is really convenient!" At the same time, he took back the talisman he had just taken out.

Walking cautiously inside, this time it was Qin Yilu who took the lead, and at the same time held a long knife in his hand - the Han Dynasty ring head knife has a straight blade, only the tip of the knife has a slight upward arc, and the width of the blade is about the same as the long sword at this time, or a little wider.

Generally speaking, it is like a larger circle of Tang knives - the ring head knife is the predecessor of the Tang knife. In fact, there are many types of Tang knives, with different functions, the appearance of the instrument knife is closest to the ring head knife, and the Chixiao used by Liu Xuan should be regarded as a horizontal knife, which is a kind of Tang knife specially used for fighting.

Liu Xuan didn't understand these specific things, although he knew what Tang Dao looked like, he didn't check it that much, anyway, it was enough for him to know what he liked.

At this time, holding the hilt of the knife on his waist, Liu Xuan walked inside, feeling the flow and change of the aura of heaven and earth around him, and observing the terrain here.

After walking for about half an hour, everyone entered a slightly open cave, perhaps there was light coming in, and there was a pond not far from them, which refracted part of the light, making the cave a little brighter.

Everyone was looking at the environment, but Liu Xuan was keenly aware of the unusual place here.

"Your Majesty has already noticed it?"

Shi Daoren was very concerned about Liu Xuan's movements, and when he saw the change in his expression, he immediately knew that Liu Xuan had discovered the location of the 'back door'.

He was very surprised by this, when he accidentally learned that there was a 'back door' in the Qin Emperor's Mausoleum, he searched for several years, and even if he found this cave, he wasted a while to find the location of the 'back door'. Why did this young genius find out at once?

"Could it be that this majesty is also proficient in the art of wang qi and feng shui?"

It's not uncommon to be able to find the 'back door' in this way, as it's all related skills. In fact, Liu Xuan was not proficient in this way, and he only knew a small part of Feng Shui, which was related to the knowledge of formation.

As for the Wangqi, it is completely an ability that comes with cultivating the Dragon Qi of the Son of Heaven.

Because of the exercise he is practicing now, he is extremely sensitive to the flow of aura, and since he entered this cave, he has felt that this flow is unusual, and when he arrived here, he keenly noticed that although these flowing auras seemed to be a little chaotic, they had one thing in common, they would stop in a certain area, and then hover for a while before walking away.

It was such a subtle abnormality that allowed Liu Xuan to find the location of the 'back door'.

Strode forward, and finally stood in front of a mountain wall. The mountain wall that looked no different from the side was the place where there was an abnormality, Liu Xuan stretched out his hand and touched the mountain wall slightly, only to feel that the power in his body fluctuated violently, as if he was about to leave out of his control.

If it weren't for Liu Xuan's refining of all the dragon qi in his body, maybe most of the dragon qi in his body would be consumed immediately, but even so, a small amount of dragon qi that had not been fully refined was also sucked out.

In the eyes of everyone next to him, there was a flash of brilliance, and then he regained his calm, and he didn't know what was going on, only Shi Daoren was silent for a moment and suddenly shocked, and exclaimed: "Your Majesty, be careful, this Qin Emperor's Mausoleum is full of formations that suppress dragon qi!"

He had already figured out why this kind of thing happened, and only then did he regret that he had not thought about it, the Son of Heaven's cultivation was indeed strong, but the ability to control the dragon qi was just restrained by the formation in the Qin Emperor's Mausoleum, so wouldn't it be empty-handed this time?

But he didn't want to, Liu Xuan chuckled and said: "A little fur is also taken out to show off, if you want to suppress the dragon qi in my body, this means alone is not enough." ”

Although Shicai lost a little dragon qi, but Liu Xuan didn't take it seriously, as long as he went back to cultivate well, he could cultivate back in a moment - it was originally some dragon qi that he absorbed last night, just because he was coming to this Qin Emperor's Mausoleum today, and he didn't have time to refine it.

If he only cultivated the pure dragon qi of the Son of Heaven, or could only control the dragon qi, maybe he really didn't dare to step into this Qin Emperor Mausoleum.

It's nothing if you accidentally waste your cultivation, if even you are pressed in it by the suppression, it will be even more bitter than Qin Shi Huang - then Qin Shi Huang was only suppressed here after si, and he is still a big living person, and being suppressed by the suppression is no different from being buried alive.

But Liu Xuan's cultivation is a further improved exercise, in addition to the method of absorbing and transporting, he would rather practice slower to further refine the dragon qi in his body, so that the dragon qi becomes condensed, easier to command, and more closely connected with himself.

It was precisely with such a step that he was not afraid of these formations, and the dragon qi that should have been restrained was no longer afraid of these formations specially arranged for him because of Liu Xuan's relationship.

When Shi Daoren heard Liu Xuan say this, he also secretly let out a sigh of relief, while rejoicing that today was not a daytime trip, he was also amazed at the strength of this Son of Heaven's cultivation - he didn't know the subtlety of Liu Xuan's exercises, he only thought that Liu Xuan's cultivation was strong, and he had already used the dragon qi condensed by the dynasty to be able to confront those magic circles.

But he didn't know that the actual situation was not like that at all, but Liu Xuan didn't need to explain it to him in detail, and after observing it for a while, he finally understood the composition and situation of this magic circle.

Seeing Shi Daoren come forward, he said casually: "At the beginning, this magic circle just wanted to be used for a short time, which means that except for the period when it was just arranged, this magic circle will be automatically abolished, which is equivalent to nothing." ”

"Oh?" Although Shi Daoren has a lot of knowledge, he can't see these things, after all, although he is a first-class monk on this earth, compared to Liu Xuan, it is not a little worse.

"It's just that with the passage of time, the terrain has changed, and this leyline, which was originally just rubbed by the side, actually divided a part of the tributaries through the position of this magic array, coupled with the changes of the stars, sun and moon between heaven and earth, this formation has changed, which gives us the opportunity to enter the Qin Emperor's Mausoleum. ”

Liu Xuan didn't say it in detail, but Shi Daoren still understood, it turned out that this 'back door' was a one-time thing. Even the people who set up the formation just wanted to use it for a while, but unexpectedly, the heavens and the earth evolved and changed, and as a result, this back door was opened, giving Shi Daoren the opportunity to enter the Qin Emperor's Mausoleum.

"However, this opportunity is also a coincidence, and it can only last for a short time!"

Liu Xuan also confirmed the judgment made by Shi Daoren before, this back door can only be used for a while, and it can't be used all the time: "Moreover, after this time, this formation will be truly and completely scrapped!"

"Oh?

"This formation was originally used temporarily, and the strength was not high, and after this time, the thing that set up the formation could not withstand the strong force, and it would eventually destroy it from the inside...... If the equipment used to set up the formation is destroyed, the formation will naturally be wasted!"

Shi Daoren nodded, he could only see the opening and approximate duration of this formation, but he couldn't see such a detailed thing, he didn't expect that this young man was not very old, and his knowledge was much stronger than himself.

was about to ask again, but saw Liu Xuan's finger on the wall, and then the wall was flooded with a blue halo like water, which looked very beautiful, but Liu Xuan didn't even have the interest to look at it, and walked in directly.

Everyone saw that the blue water light did not move for a while, and Liu Xuan disappeared like this, Qin Yilu and Huang Zhong were naturally shocked, and immediately rushed in, and Diao Chan was also unwilling, so he quickly followed.

Shi Daoren was stunned for a moment, only to realize that everyone except himself had already entered.

"I thought I was going to waste a lot of effort to open this 'back door', but I didn't want to open the door in the eyes of His Majesty, this opening was just a matter of pushing. ”

Shaking his head, gradually realizing the gap between himself and this majesty, Shi Daoren thought that this time when he entered the Qin Emperor's Mausoleum, he had to keep a low profile, otherwise he would annoy this one, and he was afraid that he would not want to get that pill.

Walking to follow, he only felt a coolness around him, but he felt a sense of depression in his heart, and these feelings were fleeting, and after his eyes were flowering, he came to another place.

Liu Xuan was standing not far away, and after seeing him follow, he deliberately glanced behind him. Shi Daoren also turned around, only to see a light blue light cluster behind him out of thin air, like a gate floating there.

"This gate lasts for a maximum of three days, and you have to leave here within three days. ”

Liu Xuan took a look and knew the time limit for this door.

"Didn't you say one month, how could it be changed to three days?" Diao Chan didn't understand this very well, wondering why it was so bad.

Liu Xuan explained to her: "The so-called one month means that there is still one month to open this door, but after it is opened, this door can only last for three days." ”

"I see!" Secretly sticking out his tongue, Diao Chan didn't expect that this time it would only be such a short time. Looking around, "Not far in front of him, there is a huge palace that is not inferior to any palace in Chang'an City.

And the space they are in is also very large, not the stuffy environment they thought at first. When I looked up, I could see many stars shining, and I didn't know that I thought I was in the wild. If you look closely, it turns out that countless night pearls are embedded on the top, and they are arranged in the shape of stars.

"Is this the interior of the Qin Emperor's Mausoleum?"

Just as he was sighing, Liu Xuan suddenly looked into the distance: "This Qin Emperor's Mausoleum is really not ordinary, there is something to welcome us so soon." (To be continued)
