Walking through the dark corridor, Wen Qingzhu and Fu Lie came to a corner, and when they turned the corner, their eyes suddenly lit up.

Suddenly from dark to bright environment, the two couldn't help but squint.

After getting used to it, he completely opened his eyes, and Wen Qingzhu found that what appeared in front of him was a sliding door, and the strong light came from the round light on the wall, which did not look like a candle, let alone a night pearl.

Fu Lie suddenly looked back, and Wen Qingzhu's hand tightened.

"What's wrong?" She hurriedly looked back, and found that the way she had come had disappeared, but instead there was a staircase.

Wen Qingzhu was stunned and said, "The way in is gone!" ”

Turning around and continuing to walk forward, Fu Lie's voice was very reassuring: "It's okay, I will accompany you." ”

The two walked to the sliding door, which was a checkered door built in imitation of the previous dynasty.

Through the curtains, they could faintly see a figure swaying inside.

Fu Lie knocked on the door and said, "Is there anyone inside?" ”

Waited for a few moments, but no one answered.

Wen Qingzhu stretched out his hand and tried to push, but found that there was a bell sound inside, but the sliding door moved and retracted.

"Bells?" Wen Qingzhu felt that something was wrong, and this door seemed to be blocked by someone inside.

Looking sideways at Fu Lie, his eyes were solemn.

Just as they were thinking, there was a dull thud around the corner.

Wen Qingzhu immediately turned around, feeling very uneasy.

"I'll go over and have a look." Fu Lie wanted to look around the corner again, but Wen Qingzhu subconsciously grabbed his hand.

Fu Lie turned around, only to see her slowly shaking her head: "Can't pass!" ”

Looking around, Wen Qingzhu remembered that she was in the back mountain of the Medicine God Valley, and these passage rooms looked similar to the passage rooms over there.

Based on Tazawa and Wushui's words, she was already sure that this place had something to do with the Medicine God Valley.

If that's the case, then there will definitely be a way to open the sliding door in front of you.

Wen Qingzhu walked to the door, and Fu Lie followed, without acting rashly.

There was a clear knock in my ears, getting closer and closer.

Suddenly, Wen Qingzhu remembered the first knock in his mind, and the knock sound has always been regular.

She had just tried to push the door open, with minimal force.

In Wen Qingzhu's cognition of musical rhythm, each musical scale is obtained through mathematical algorithms, that is, each musical scale has a long and short length.

In order to prove his guess, Wen Qingzhu stepped forward, recalled the length of the second knock just now, and pulled it according to the length of the horn calculated in his heart.

A bell rang again, and it was noticeably different from just now.

And the knocking sound behind him became more and more urgent, Wen Qingzhu suddenly understood, and quickly began to pull the sliding door, and bells of different heights rang one after another.

Until the knock was already approaching the corner, and Wen Qingzhu finally opened the door.

A pale golden light shone out inside, and the decoration in the small room was very simple.

The most important thing is that there are no tables and chairs in the house, but small tables and seats.

A man with a black cloth draped over his head sat cross-legged in front of them, with an oval green glass vase with a dry plum branch stuck in it.

To Wen Qingzhu's surprise, there was water in the vase, but it was rarely just past the bottom of the dead branches.

The two walked in, and the sliding door suddenly closed automatically.

Fu Lie immediately turned around, only to hear the knock outside the door slowly moving away.

"Don't worry, we're not there yet, I probably know how to do it." Wen Qingzhu pulled Fu Lie to sit down in front of the black cloth man.

As soon as he knelt and sat down, the black cloth man in front of him stretched out a pitch-black hand, which made Wen Qingzhu think of one hundred and ninety-three hands at once.

There was a piece of paper under his hand, which was pushed in front of Wen Qingzhu and Fu Lie.

Looking at it intently, there are two words written on it: dark incense.

Wen Qingzhu thought for a while and said, "May I ask this gentleman, what does this mean?" ”

The black cloth man didn't speak, but there was a sudden click on the wall, and the two of them looked together, and found that a glass funnel stretched out of the wall, and one flipped, and the fine sand on it began to fall down.

"Is this a timer?" Fu Lie twisted his eyebrows and looked around carefully, there was a hanging painting behind the black cloth man, which seemed to be the scene in this house.

In the early days of the previous dynasty, there were people with black cloth on their heads, small tables and seats, and glass vases.

Contrary to what they actually encountered, the plum blossom branches in the painting are not dry, but blooming with seven fiery red plum blossoms.

Wen Qingzhu naturally saw this scene, and she quickly stared at the glass vase in front of her and began to ponder.

If they want to get through this hurdle, they are afraid that they will have to solve the problem of dry plum blossoms.

"No, you look at the water level in the painting and add some water to this vase." Wen Qingzhu proposed his first method.

Fu Lie untied the kettle around his waist and added enough water to it, just enough to reach the water level of the vase in the painting.

Under their gaze, the dried plum blossom branches in front of them slowly pulled out their buds.

In less than ten moments, seven red plums bloomed neatly, just like the scene in the painting.

At the same time, plum blossoms exude a faint fragrance.

The paper on the table, the words on it slowly disappear.

The plum blossoms bloomed, but the black cloth man in front of him once again took out a piece of paper.

This time there are two words written on it: bitter cold.

"What's the point this time?" Wen Qingzhu subconsciously looked at the painting in front of him, and was keenly aware that there were more pieces of snow on the painting.

Fu Lie looked at the funnel on the wall, half of the time had passed.

"The dark incense can be understood as the fragrance of plum blossoms, so the bitter cold will never make it snow in the house, right?" Wen Qingzhu felt that this puzzle was much more difficult than the one just now. Kanshu.com

"There's no snow in the house." Fu Lie stood up and began to look around.

It soon became clear that on the right side of their entry, one of the doors was pushable.

For the sake of prudence, Fu Lie did not open it directly, but let Wen Qingzhu get up and stand at the door where he came in just now.

When Fu Lie opened the window, it turned out to be a courtyard outside, and it was still snowing, and the snowflakes drifted in, and the house was suddenly covered with snow.

The scene in the house instantly coincided with the one in the painting, and at the same time, the door next to the painting automatically opened, and a corridor inside the house appeared again.

Wen Qingzhu also noticed that the black cloth man sitting in front of him took the paper back.

Because she was standing on the side of the Black Cloth Man, she could see the Black Cloth Man holding the paper in front of her legs.

In front of the black cloth man, there was a large stack of papers.

At the same time, the funnel has retracted, and the lights on the ceiling are slowly dimming.

Fu Lie intuitively sensed that danger was coming, and directly pulled Wen Qingzhu out of the room.

As soon as they walked out, the entrance door shut.

When they were inside, they saw the sliding door.

When I came out, I looked back and saw that it turned into a door that opened and closed.

The two looked at each other, and in such a short period of time, the mechanism could not do it.

On top of that, they didn't hear anything.

Wen Qingzhu took out a silver needle and pierced it into his pain point, while trying to close his five senses.

There is still no change in the surroundings.

"Not an illusion." Wen Qingzhu's heart sank, the situation here was more complicated than she imagined.

Fu Lie opened his eyes at the same time and nodded in agreement: "It's indeed not an illusion, everything here is more mysterious than the Medicine God Valley." ”

"Let's move on." The more mysterious it is, the more curious Wen Qingzhu becomes, and she now regrets that she didn't read the book of the Medicine God Valley carefully.

This time they came to a study, which was much more complicated than the simplicity of the room they had just had.

Bookshelves, desks, and all kinds of messy pen, ink, paper, inkstones, and other things.

There was no one here, but in the corner of the study, there was an out-of-place shrine with only an incense burner on it, and an incense stick was inserted in it, as if it had just been lit.

Wen Qingzhu immediately frowned: "Is this the timer?" ”

At the same time, the window was suddenly blown open, and a book that had been placed on the edge of the desk fell down, just turning one of the pages.

With the experience of the previous room, Wen Qingzhu and Fu Lie knew that there should be no danger before the incense was burned.

When their eyes met, Wen Qingzhu walked to the desk and picked up the book on the ground, which was a collection of unfinished couplets, and the page that was turned was exactly without the next couplet.

Fu Lie walked to the place where the window had opened just now, he tried it, but the window didn't move at all.

The windows here are not controlled by human beings.

There was no result here, so Fu Lie returned to Wen Qingzhu's side, saw her take the pen on the table, dipped it in the inkstone, and began to write the next couplet on the book.

After writing, the window that had been opened earlier suddenly opened again.

After opening and closing quickly, the wind blew in, and more than a dozen books fell from the table.

Fu Lie picked up all the books one by one, some were geography, some were arithmetic, some were history books, and so on.

Just like just now, there are vacancies on this page that is opened.

Fu Lie also immediately picked up the pen and began to fill in the blank space.

The first two books were quite simple, but when they reached the third and fourth books, Wen Qingzhu and Fu Lie were a little difficult.

But fortunately, they were Ji Shang's apprentices, and the blank space would not, so they turned the page in front and quickly remembered the answer.

Next, one is harder than the other.

When it comes to the last book, there is only one question on it: Who does Princess Qingyun like?

Wen Qingzhu flipped through the front and back, and they were all blank.

There was no hint, which made Wen Qingzhu a little annoyed.

How did she know who Princess Qingyun liked?

"It's just embarrassing for us!" Wen Qingzhu felt that this time the difficulty was much worse than just now.

Fu Lie looked at the incense burner and said, "The time is almost up." ”

"So fast?" Wen Qingzhu was a little anxious in his heart, but his mind was still calm, and things about the princess of the previous dynasty began to appear quickly.

According to the history books and wild history, a very three-dimensional image came to mind.

There is no appearance, but the personality and behavior are very clear.

Suddenly, Wen Qingzhu picked up the pen and wrote two words: Jin Guo.

The incense burned out, and when the last bit of ash fell, the front door opened again.

Wen Qingzhu put down the book in his hand, and at the same time, the lights in the room began to dim.

The two continued to walk out.

This time when I walked out of the house, the door still closed automatically.

Instead of immediately going to the next place, they began to sum up the experience of these two rooms.

"Every time there is a problem, it seems to be two, in one room, the difficulty of the problem is about the same, but in the room just now, the difficulty of the second question is dozens of times more than the previous one." Wen Qingzhu knew very well that there must be a connection here.

Fu Lie pondered and replied: "It's two questions every time, is it because there are two people who came in, just now in the first room, we solved the first puzzle, and the time was just over halfway, but in the second room, you answered the couplet almost instantly, isn't that the case, so the question suddenly becomes difficult?" ”

"That's a bit accurate, isn't it?" Wen Qingzhu looked around, feeling as if someone was secretly spying on him.

Fu Lie looked ahead and said, "Maybe we need to go to the next place to verify it." ”

After deliberating, they went to the third room.
