The dust falls off, and the seemingly complete stone wall is made of multiple stone bricks, and the patterns on the wall are staggered and separated as the stone bricks move, constantly flipping and receding to all sides like origami.

Yun Feng had never seen such a superb art, and under the strong desire to learn, he couldn't help but explore it, not seeking to understand the principle, but to see the inner structure.

Helplessly, he didn't see anything. Because at the moment of his probe, he was stuck in a stone brick.

"Nima. Yunfeng pushed the wall, trying several methods but couldn't pull his head out.

"Damn. What's even more sad is that the stone wall is slowly returning to leveling, and if he doesn't pull his head out, he will "hang" here.

"What are you doing? A sweet voice mingled into Yun Feng's stupid curse.

At that time, Yunfeng couldn't care about who came, he hated it most when people asked him, "What are you doing?", and if he wanted to change to the usual, he might reply: "Who is it, why do you want to her." ”

However, at this time, his head was struggling in the crack of the stone, and the sound was like a vine that appeared in time when he fell off a cliff, becoming his last hope, and it sounded extremely joyful.

"Quick, pull me out. Although Yun Feng felt like as soon as the words came out, if he could save his life, he would be like once.

The girl also figured out the urgency of the matter at this time, put her hands on Yunfeng's shoulders, raised her legs, and kicked on the wall, with the demeanor of a dog peeing, and dragged it back.

"No, it's too tight. ”

Yun Feng could feel that the girl's strength was not small, and the force on his shoulders made him feel a sense of tearing.

"Come from behind. ”

The stone bricks are closed, and the cloud wind lives in a half-line.

The girl turned her hips over, and she didn't care about Yunfeng's strange posture of arching her body, sticking to her buttocks, pulling Yunfeng's shoulders, kicking her right leg hard against the wall, pumping back hard, and pulling Yunfeng to the ground.

The stone bricks are closed.

"Get down, if you don't fall to your death, you'll be crushed to death. ”

Yun Feng rolled down from the girl's body, and her head was pinched by the lack of oxygen, and she didn't come back to her senses, so she only thanked her.

"It's you. Yun Feng only then saw her face clearly. The road is narrow, and the other party is actually the strange one who "quenched his thirst" at the Lostant Academy that day.

Thinking of this, Yun Feng subconsciously touched his buttocks, thinking of the scene just now, he couldn't help but be discouraged, and he had nothing to love.

"Have we met?" the girl looked puzzled.

Looking at her sincerity, it really makes people wonder if she has recognized the wrong person. Ran Yunfeng did not hesitate at all: "Don't talk nonsense, take the money." ”

"It turns out that your life is not worth these few gold coins, and that is too cheap. The girl was at ease.

"Okay, you stick your head back into the wall. I'll give you twice as much. ”

At this time, the stone wall was closed, and Yun Feng had nothing to refute, and asked, "Who are you? Why are you here?"

"Why can't I be here. ”

"Are you...... Senior Sister Yu?" Yun Feng remembered at this time that Yuan Yuan had mentioned a little junior sister named Yu Mengdie, who started earlier than him, but Yun Feng had never seen it, so he didn't expect to meet him here today.

"I heard Granny Hua say that there is a librarian from the academy, named Yun Ji, it's you. ”

"But my mother-in-law didn't say that it was a second force, I'm curious about how you passed the assessment. What the other party was referring to was naturally Yun Feng's behavior of being caught in the head just now.

"Thank you Senior Sister Yu before. Although the stone room was dark, Yun Feng's gaze was embarrassed to stay on the other party, but looking at the appearance, Senior Sister Yu should be younger than him.

"Thank you for your sincerity isn't enough, isn't it?"

"How much. ”

Yun Feng wasn't worried about offending the other party. In her heart, Yu Mengdie is already the image of a money fan.

"I heard that you challenged the black gold list some time ago and made a lot of money. Yu Mengdie's news seemed to be very well-informed, but she turned to say: "Don't worry, senior sister is not a mercenary person. ”

Although Yun Feng is only a nominal librarian, there are no teachers in the academy to teach, and there is no distinction between students and students.

"Senior brother. Yu Mengdie hugged Yunfeng's shoulder, it seemed that the two of them had already become acquainted, and they didn't care about the difference between men and women, and said, "Do Senior Sister a favor." ”

The girl develops earlier than the boy, and although Yu Mengdie is smaller than Yunfeng, she is half a head taller, like the eldest sister holding the younger brother.

However, Yun Feng didn't eat this, shook off the other party's hand and said, "Senior sister still talks about money." ”

"You just don't give my sister face. ”

"How dare you. It's just that the junior brother's ability is limited, and I'm afraid that I won't be able to help much. ”

"I haven't said anything yet. ”

"Then let's not talk about it. ”

......

"Just kidding, senior sister, you say, what's the matter. ”

"Follow me. ”

At this time, Yunfeng found that they were in a stone room. The stone chamber is not large, and there are many hollows in the wall, and many books are placed.

Yun Feng picked up a stack, and before he could read it carefully, the title of the book had already surprised him: "This is ...... Skills? It's all here?"

A passage connects large and small stone chambers in series, some with closed doors, some open, and the items stored in the stone chambers are different, including utensils, weapons, and the most are books, and there should be thousands of pieces by sight. It's no wonder that Yun Feng is amazed, the skill is undoubtedly the most valuable secret book in the world, and the most basic ones are monopolized, and there are very few of them circulating. There are only a handful of academies that can collect so many skills, and there must be only a handful of them in the entire Twilight Continent.

"Awesome. Yu Mengdie said a little proudly, snatched the book slip from Yunfeng's hand and put it back in place, "The skills here are too complicated for you, and there are many forbidden techniques, don't blame the senior sister for not reminding you, if you look at it indiscriminately, you will die an ugly death." ”

"These are all open to students, but there is a prerequisite: that is, cultivation is above the Heavenly Walk, and in addition to that, there is a path. ”

"The top of the black and gold list. Yun Feng said for her, which is also the reason why he participated in this list.

At this time, Yunfeng realized that the ultimate goal of his fight had another way to achieve, but if he stole books without consent, it was no different from plagiarism.

On the one hand, Yun Feng was desperate to find an answer that he couldn't perceive, and on the other hand, he didn't want to break the rules of the academy. While pondering, he followed Yu Mengdie to a stone room.

"Can you open it?" asked Yu Mengdie.

On the stone gate, the word "land area" is engraved, and Yunfeng guesses that it should be a record of the Twilight Zhao Continent. Other than that, there are no switches set on it.

"I've looked around, but there's no mechanism. In fact, Yu Mengdie is also the first time to enter the cabinet. At another entrance, she spent ten days cracking the Nine Sons Alliance.

"What's inside?" Yun Feng asked. For this senior sister who appeared out of thin air, he was vigilant.

"Well, I won't know until I open it. Yu Mengdie said that she didn't know, and like Yunfeng, she also guessed based on the name of the room: "I'm looking for a book, it's probably in this stone room." ”

Yun Feng carefully looked at the stone room in front of him, and as Yu Mengdie said, he didn't find any opening mechanism, nor did he set it up like a nine-son joint lock.

"Permission may be required to turn it on. Yun Feng speculated in his heart, and stepped forward to wipe the word "land domain".

"Da ......" was unexpected, and the stone door suddenly opened. Frightened, Yun Feng took a step back.

"Awesome, junior brother. Yu Mengdie didn't notice Yun Feng's surprise, and exclaimed, "How did you discover the mystery of these two words?"

"Well. Yun Feng made a confident look, and then said, "I just saw that the words on it were a little dirty, and I wanted to wipe them clean." ”

"That's it?"

"That's all. ”

"Okay. Yu Mengdie was suspicious, but she didn't expect that the stone room that she couldn't open after racking her brains was actually opened by Yunfeng by mistake, which made her somewhat frustrated.

"I've never had a crush on Virgos. Yu Mengdie continued.

"What do you mean?

"Nothing. Yu Mengdie entered the stone chamber and began to look for the book she had spoken.

This stone room houses large and small wooden boxes or bamboo tubes, which exude a faint woody fragrance. Yunfeng recognizes this wood, which is not only hard but also naturally insect resistant, and is an excellent storage tool after special treatment.

Yun Feng was very interested in the books in this stone room, and he found that the collection here was basically a collection of strange magazines about the geography and humanities of the Twilight Zhao Continent, such as "Does Another Dimensional Space Exist", "The Secret Story of the Twilight Zhao Forbidden Domain", etc., as well as "The Revelation of the Passage of the Dead" just by listening to the title of the book. And before that, Yun Feng had always thought that the undead were just a legend, and it wasn't until the Requiem Festival undead appeared some time ago and heard Yuan Yuan talking to the monk that he understood how lacking his information was.

"Senior brother, come over and help my senior sister. Yu Mengdie searched for a while in the stone room, and it seemed that she had found her target.

"Here. She pointed to a concave wall above and said to Yun Feng, who came over: "The third bamboo tube above, the big one." ”

"No, no, no, it's too troublesome, and you have to empty the wooden box underneath. Yu Mengdie stopped Yun Feng's plan to climb on it to help her take the tube.

"So, you squat down and carry me up to get it. ”

"......" Yun Feng didn't reply, what he thought in his heart was: I will be an immortal banban.

However, Yu Mengdie didn't care whether Yun Feng was willing or not, and urged: "Speed." ”

Although it is always better to look at people at night than during the day, especially in this kind of light now. But it is undeniable that Yu Mengdie is handsome, she has thick eyebrows that are rare for women, and her eyes are very bright, like a wild boar.

If the eldest husband can bend and stretch, he should repay the kindness just now. Even if Yunfeng is aggrieved, he can only comfort himself like this.

"Okay, wait a minute. Yu Mengdie gathered her skirt, straddled Yunfeng's shoulder, patted her shoulder, and signaled that she had sat down.

"Sit tight. Although for a moment, Yun Feng wanted to throw the other party into a dog and eat, but in the end he didn't take action.

He had no choice but to stand up and ...... Rise...... Groove ...... I almost couldn't get up.

careless, Yun Feng didn't expect that the seemingly petite senior sister was not light, and she really felt like she was carrying a pig.

At this time, Yu Mengdie, who was compared to a wild boar by Yunfeng, was snickering, and the reason why the other party felt that she was carrying a thousand catties was only because she gathered her energy and pressed down, deliberately tricking Yunfeng.

"Okay, got it. ”

"Senior Sister Yu, I can't see it, your tonnage is not big, but the mass density is not small. Yun Feng was out of breath, even when he was practicing the Spirit Star Dance, he had never been so tired.

"Beat around the bush, if you want to say that I am serious, just say it. Don't worry, I won't tell you about your kidney deficiency. Yu Mengdie's meaning is obvious, Yunfeng can't even carry a girl, presumably because she is not in good health.

Defeated on top of his tongue, Yun Feng didn't say anything more. Yu Mengdie opened the bamboo tube and carefully took out the skin of an unknown beast from inside. Spread out, basically the stone chamber is paved.

"Is this a map?" The stone chamber is dark, and the map on the animal skin is somewhat different from the regular one, except for the dense lines of different thicknesses, there are also very detailed markings, and Yun Feng can't understand it at all.

"Twilight... Plane... War... Fig. Yun Feng noticed that the lower left side of the animal skin was a very ancient script, and he had sent someone to collect artifacts with this kind of script, but it took several years to find only some fragments.

The words marked on the animal skin are available in various periods and countries, and Yunfeng knows a rough idea.

Yu Mengdie only glanced at it, and confirmed that this was what she was looking for. She took out an unknown paint and spread it evenly over the hide.

"Want to help?" Yun Feng asked. This paint is a bit pungent and has a relatively strong fragrance.

"No, I don't. Yu Mengdie didn't let Yunfeng help this time, maybe she didn't feel at ease to let others operate.

This also saves Yunfeng trouble, but looking at Yu Mengdie's speed, I am afraid that the time to paint the entire animal skin will not be short. Yun Feng was also very curious, there were no traces of this beast skin, it should have been peeled off from the whole body of the alien beast, but what kind of alien beast had such a volume?

"It's ...... Dongxu Academy?" Yun Feng felt that there was a place that looked familiar, like the foothills near Dongxu Academy, and after a closer look, the word "Dongxu" was written next to it, and it should be added later.

However, except for the foothills near the Dongxu Academy, the rest of the Shire Kingdom is not marked on the map.

At this time, Yun Feng remembered what Yuan Yuan had asked him to help with - if he could enter the third part of the Book Pavilion, he would borrow the drawings of the Dongxu Academy when it was originally built.

Yun Feng was still puzzled at the time, because the rubbing version of the floor plan of the academy was available in the second part of the library, and he had read it carefully. However, Yuan Yuan said that there should be another copy in it, and it was right to take it out when he saw it.

"Hey, yes. Yun Feng just looked for it in the stone room with the mentality of giving it a try, but he didn't expect to see a large copper cylinder of "Dongxu Academy Drawings Collection".

Pulling out the animal skin inside, there is a general plan of the building of Zhang Academy.

At this time, Yu Mengdie had already wiped the animal skin on the ground with the coating liquid, took out several large white papers from the bamboo tube she carried, fully covered the animal skin, and then gently crushed it with a wooden pole, everything was carried out in detail.

Although there was no trace on the white paper, Yun Feng had already guessed that she was copying the map.

"Senior sister, lend me some paint and paper. Yunfeng learned from each other, thinking that copying was a good way to avoid the possibility of being discovered.

Yu Mengdie put the paper and animal skin into the tube: "Yes, five gold coins." ”

"Who just said that he is not a mercenary person. ”

"Senior brother, don't say five gold coins, even fifty gold coins you can't get this paint. ”

Yun Feng also felt that what Senior Sister said should not be a lie, if the paint could really perfectly reproduce the text pattern, it must be an unusual thing, at least he had never heard of such an item.

"Senior sister, I'm a very timid person, and I can't keep secrets, and I always want to talk to someone. Yun Feng's meaning is obvious, if Yu Mengdie refuses to lend the paint, it is likely that she will report to Granny Hua about copying the map tonight.

"Senior brother, I didn't expect you to be timid so quickly at such a young age. Yu Mengdie sympathized.

"What do you mean. Yun Feng thought to himself, it wasn't hair loss, what does timidity have to do with age.

"Have you ever heard a word, the newborn calf is not afraid of tigers. ”

"I've heard it, and then what?" is a popular proverb, and Yunfeng naturally knows it.

"When people are young, they are not afraid of heaven and earth, and they have no scruples, but when they grow up, why are they afraid and cautious everywhere. ”

"Why. Yunfeng asked rhetorically.

"Because whether a person is bold or not is related to the kidneys, when they grow up, the kidneys are easy to overdraw, and the gall will become smaller. Yu Mengdie sneered.

"Damn. "Yun Feng has nothing to say about Yu Mengdie's routine.

"Take it, remember you owe me five gold coins. Yu Mengdie finished playing tricks on Yunfeng and handed him the paint.

"After rubbing, mix turquoise powder with a little water, and the detailed treatment method is in the "Ancient Method of Rubbing". Yu Mengdie reminded that it seems that this is a technical project.

After the cloud wind is processed, the two cylinders are put back in their original places, and then the footprints on the concave wall are wiped off, striving to leave no traces.

"Senior sister, did you hear anything? "The night was quiet, the stone room was silent, and the wind was silent, but Yunfeng heard a strange sound.

This kind of cooing, similar to the cooing of birds, comes out in an irregular way, and it feels like the sound source is nearby, and it seems to be extremely far away, which is very scary.

Yun Feng leaned over to listen, but received a slap in the head.

"Do you have anything to eat? "Yu Mengdie was already hungry. It's no wonder that she hasn't eaten all day.

"Five gold coins. Yun Feng finally had a chance to fight back, and handed her the two steamed buns he brought when he came in.

"Robbery. "Even if it is the most fragrant Li Ji bun in the Golden City, two steamed buns cost less than a silver coin.

"Eh, it's not worth it in normal times, but here and now, there is this price. "Yunfeng is very confident.

"Yes, junior brother, I learn quite quickly. Yu Mengdie, who was hungry, stopped bargaining, took the steamed bun and started nibbling.

The steamed buns are flying, and the gobbling Yu Mengdie is like a wild boar arching food.

After a while, the two steamed buns have been completely wiped out, and the two are about to leave.

"Senior brother, do you feel very hot?" This time it was Yu Mengdie's turn to notice something abnormal.

"Is it early summer today?" Yun Feng asked, these days of early summer are the hottest time of the year.

"yes, no wonder it's so hot. Yu Mengdie was stunned.

"I mean, have you ever seen someone wearing cotton pants in early summer?" Yun Feng had a question when he carried her before.

"You know what, it's called fashion. Yu Mengdie said.

"It's not fashion, it's called turtles. "Although the clouds and winds are passing, I do feel that the temperature is rising.

"Senior brother, should you put ...... in the steamed buns" Yu Mengdie looked unexpected, as if Yunfeng had drugged her and plotted against her.

However, Yun Feng was not in the mood to joke with her at this time, the temperature of the stone room had risen significantly, if it was like the scorching sun breaking through the clouds to shine on the earth before, then it was undoubtedly falling at this time.

"Let's go. Yu Mengdie was not playing haha, as if facing a great enemy, she withdrew from the stone room with Yunfeng.

"Bang!" However, as soon as he and Yunfeng rushed out of the stone gate, a wave of heat burst out of the passage, knocking the two of them to the ground.
