Peony shone the face of the girl lying on the ground with the faint fire light in her hand, and after a moment of careful observation, she became puzzled: "I always feel that I have seen it somewhere...... Ah, I remember!"

Lu Tao also remembered, isn't this the little palace maid of Concubine Ling?

The last time I secretly hid in the lake of Yaochi, I saw this little palace maid, at that time, Lu Tao was still thinking about her relationship with the person dressed as another noble lady on the boat, and later learned from Peony that the noble lady was a member of the emperor's harem Ling Guifei. Although it can be heard from the conversation that these two people not only have different plans, but the relationship between them is not ordinary, but Lu Tao does not plan to delve into it, and he does not have the ability to delve into it, but he did not expect to meet this unusual little palace maid here.

Peony hesitated for a moment, and said to Lu Tao: "Don't worry about it for now, tie her up and throw her in the house, what kind of conspiracy does she and Concubine Ling have, when I bring her back, I can torture her slowly!"

Lu Tao nodded, and helped Peony drag the little palace maid dressed as a eunuch to the firewood room behind, the firewood room was empty, there was nothing, and no one would come.

......

"Yesterday we walked the hole on the left......" Peony muttered: "Anyway, no one will come here except for the little palace maid above, we have time, why don't we explore these two holes?"

Lu Tao nodded noncommittally: "Then which one shall we try first?"

Peony raised the lantern in his hand, but did not answer Lu Tao's question first, he asked Lu Tao in turn, "What about your handy ball of light last time?"

Lu Tao: "......"

He also wanted to release the lighting, but unfortunately the spiritual power in his body was now completely imprisoned, not to mention the lighting technique, and Lu Tao couldn't use the simplest object control technique.

Shaking his head, Lu Tao could only explain: "That has a cooldown time, and it can't be used for the time being." ”

"Hmm...... Okay, so let's take the one on the right. ”

Lu Tao: "???"

He really didn't understand what kind of reason Peony chose the right side, but these are not things worth pondering, the right side is the right side.

After walking about four or five hundred meters inside, Lu Tao found that the passage on the right was not a smooth road, different from the place he came in just now, the passage in front of him became narrower and narrower the more he walked, and he had to bow his head to move forward so as not to touch the cave wall above his head, and then he had to bend down to move forward.

Under the dim light, Lu Tao could only see the figure of the peony clearly, and there were black holes on both sides of the cave walls, which could scrape off a layer of moist soil when touched.

After walking for a long time, he had already come to the end of the passage, taking advantage of the lantern in his hand, Lu Tao looked up and found that the entrance of the cave was straight up, but he didn't know how high it was, and then he disappeared into the darkness and couldn't see it really.

"Can this be climbed?" muttered Peony, but still poked up with the lantern in his hand, trying to find out if there was anything to climb.

Lu Tao's eyesight is much better than that of Peony, he can see the clue at a glance, the location of the cave entrance is faint, there will be a small pit every other distance, obviously a place for hands and feet to climb. As long as you climb up these pits, you should be able to climb all the way to the top of the cave.

"Let me try. Lu Tao spoke: "You help me hold the lantern below." ”

With his eyesight, it is easy to see these pits, but Peony is not necessarily, she yearns to climb up, so she can only climb with a lantern in one hand and the other hand, which is simply impossible.

"Good. Peony took a step back and gave up the position of the cave entrance to Lu Tao.

Lu Tao reached out and tried the pits, and found that they were different from the surrounding dirt walls, and the hard touch seemed to be carved out of stone.

If you look closer, the same is true, this upward passage is basically a whole stone with a circular passage straight up and down in the middle.

Climbing on top of these pits carved out of the stone wall, Lu Tao quickly reached the top, the top was covered by a stone slab, and a hole appeared on the right side, Lu Tao put his eyes into the hole, but found that it was pitch black inside, and he couldn't see anything.

Lu Tao tried to push the stone slab above his head hard, with the friction sound of the "click" stone slab, this rather heavy stone slab was lifted, Lu Tao sent the stone slab to the side, revealing an opening for only one person to enter and exit, Lu Tao poked his head out and looked out, but the realization was blocked by a row of bookshelves.

"How's that? what's in there?"

Below, there was a voice of peony asking, and Lu Tao glanced back: "I'm not sure yet, but I saw a row of bookshelves." ”

"Bookshelves?" Peony's voice was a little puzzled: "Could it be the Scripture Pavilion?...... Let's go up and have a look!"

As he spoke, Peony bit the lantern in his hand in his mouth, and then climbed up along the route that Lu Tao had just climbed.

The room was finally brighter in the light of the lanterns, with rows of bookshelves lined up one after another, revealing criss-crossing passages.

"This is not the Scripture Pavilion......" Peony swept the books on the bookshelf with the lantern in his hand: "I have been to the Scripture Pavilion, it is completely different from here, and these books are ......"

Lu Tao looked at the lantern in Peony's hand, and all the books placed on the bookshelf between them did not have any words on the spine, and they were like this when they looked at more than a dozen books in a row, and they took down one casually, Lu Tao also did not see any text on the cover, and when he opened it, the article written in the book using a certain kind of text that Lu Tao did not know at all was neither the text on the land of China that Lu Tao knew, nor the words unique to this world.

Showing the text on the book to Peony, Lu Tao opened his mouth and asked, "Do you recognize the words on it?"

Peony stared at the crooked words on the book like tadpoles, frowned, and meditated for a long time before he spoke: "I don't know, I've never seen such words. ”

Shaking his head, Lu Tao inserted the book back, if all the books on the shelves were like this, there were no names on the outside, and the words inside could not be understood, then these books would be useless at all.

Peony didn't have any frustration, she raised the lantern in her hand: "Let's take a look around, there should be nothing to see here." ”

Lu Tao nodded, thinking that the only thing Peony cared about should be the heirloom jade seal she mentioned before.

This place is different from the three-story building that Lu Tao had been to before, whether it is on the ground or on the shelves, and even on the books neatly placed on the shelves, they are all full of dust, and it seems that no one has ever come to clean them, not only that, in this room full of bookshelves, even the windows are only the size of a palm, and only a faint moonlight comes in from the outside, leaving diamond-shaped spots of light on the dusty ground.

Bypassing all the bookshelves, Lu Tao and Peony soon saw a door at the end of the passage, and approached the door, Lu Tao found that it was actually a heavy iron door, Lu Tao did not see the location of the keyhole from the outside, and Peony, who was walking in front, pushed hard, but found that the door seemed to be unable to be opened.

"Over to you. Peony looked at Lu Tao and got out of the way of the door by the way.

Lu Tao nodded, although the spiritual power in his body is now as solidified as cement, but the strength of his body is still there, so he can try to push it away.

Putting his body against the door, Lu Tao began to exert force, as his strength gradually increased, the iron door also emitted a piercing metal friction sound, hearing this sound, Lu Tao was worried that such a harsh sound would attract someone, and increased his strength, with the last piercing buzz, Lu Tao pushed the door out of a gap that could accommodate people to pass through and stopped.

Taking a breath, the door was really tight.

Peony held a lantern in her hand, looking at the door with some hope, she didn't care about what to say to Lu Tao, and went straight into the narrow gap.

Then, there was an "Ahhh
