The summer in Baisatin City is as hot and humid as ever, and many times people fall asleep listening to the "tick-tock" sound of the raindrops. I've always loved rainy nights, the sound of the rain always gives people a sense of peace of mind, and the worries of the day seem to disappear with those "broken beads".

It is common to wake up in the middle of the night, and after waking up, I habitually closed my eyes and groped for the quilt on the bed, and I didn't find the quilt after groping for a long time, but I fell asleep after looking for it.

In a daze, as if someone had made me fall asleep on purpose, and after a while, a strong sense of sleepiness gradually disappeared, and I opened my eyes in a half-asleep state.

It was pitch black all around, and I couldn't see my fingers, so I had to open my hands and scratch indiscriminately, moving forward little by little.

Am I dreaming? Is it so dark because of your eyes closed? Strange, why do you still have consciousness when you dream? A cold wind blowing from nowhere poured into my trouser legs, making me cold for a while, and my upper and lower teeth fought.

Walking like this, I didn't know what would appear in front of me or behind, I tensed my nerves, ready to deal with possible threats, but I also thought that even if there was anything unclean in my dreams, I wouldn't dare to do anything to me. Remind yourself like this, and the tight strings in your heart will be relaxed, and you will no longer think about anything that scares you.

My eyes must have adapted to the dark environment, and I could see something vague, at least I could see a gray path walking under my feet. My eyes widened, hoping to see something in this dark dream, and as I expected, at the end of the path, there seemed to be a glowing ball, and the only light source from the ball of light in the pitch black environment was particularly eye-catching, and I was tempted to run up quickly to find out.

I was so poor that I finally caught up with the glowing orb, and I was exhausted and panting, but I was able to get a glimpse of it.

Take a closer look, where are the "light balls", which are clearly suspended white crystals, perhaps too far away to see the dazzling eyes.

I approached one of the nearest crystals, and when I looked closely, the crystals were divided into two parts, containing glowing white sand, and the upper part was flowing little by little to the lower part. What's new about this? Is my imagination so strong that I can still see things I don't see in reality? The constant flow of questions prompted me to approach the glowing crystal, and the moment my fingertips touched the crystal wall, it shattered into countless tiny particles, which eventually disintegrated into powder and disappeared.

Where crystals once appeared, they were replaced by a bookmark. At this time, my bookmark seemed to receive the same kind of induction, and it also appeared, floating opposite the bookmark.

I watched this magical scene with great concentration, and suddenly, a cold wind blew behind me, and the pajamas I was wearing were already thin, and the wind blew so directly that I sneezed.

It was because of this sneeze that I noticed the anomaly, and in addition to my voice, there seemed to be other people's voices mixed in.

"Who? Come out for me! "I watched my surroundings vigilantly, my hands and feet in a defensive posture, ready to attack the uninvited guests.

The owner of that voice appeared, a man in ancient costume, and his outfit I had seen in the Folklore Museum, a long-lost cultural heritage of the city of Baisating. It's a pity that the museum's description of the costume is too concise, and it doesn't know what hidden information is contained in the stitched old costume.

Seeing that his appearance is completely inconsistent with Xuanguo's facial features, like a foreigner, am I too obsessed with that costume? How can a foreigner be in contact with me?

The man's reaction was very strange, pointing at me with one hand, holding a bookmark in the other, and speaking in a language I didn't understand, and because of the language barrier, he and I were embarrassed.

"You're shaken," a third voice appeared.

The figure of a third person slowly emerged, a man wearing a navy blue robe and a hat.

"You... You're not..." I quickly searched for the clues before, I saw him, and it was also in this dark place!

"Sativa! Is that you! I blurted out.

After the third person appeared, the strangely dressed alien was surrounded by crystals, and in a few moments, the crystals and the man wrapped in them dissolved into pieces and disappeared.

"Who are these people, they ran away before they made their words clear! And you, I remember you, the one who spoke inexplicably! None of the clothes have changed! ”

The man paused, and I couldn't see his eyes and nose, only his mouth and pout.

"It's not important that you remember me as an oversight, I want you to solve one thing"

Is this an indirect acknowledgment of his identity? It seems that it is indeed "alfalfa", and the last question came to me again before I figured it out, so I'm so good? His words are full of questions! I want him to solve my doubts!

"Solve one thing? What's up? "I stopped the barrage of thoughts in my head.

"There's a guy who's in trouble, and his stand-in is trying to find a way to replace him, and only you can do it if you have Twilight's bookmark"

"Who's in trouble? How do you know he's in trouble? And what are Twilight bookmarks? Why look for me? "A series of questions popped up one after another like a cannon, my emotions have never been so excited, this man is simply so strange, the man in the old costume is too, and there are constantly bizarre events, why do you always come to the door one after another?

"You don't need to know that much, just do what I say."

"Why don't I do it?"

"If you don't do it, strange things will come to you one after another," the man replied calmly.

"Why do you know?"

"I told you, you don't have to know"

Listening to his stubborn tone, I guessed that no matter how much argument continued, I had to give in, sighed softly and said, "What does that person in trouble look like?" ”

"On the day of the typhoon's landfall, you met him on the way home, his car was hit by lightning and burned, and you are blamed"

When it comes to "burning the car", I have palpitations, and I was chased all the way by someone I don't know, and if I hadn't run fast, I would have been knocked out by him.

"That kind of person... Why should I help him" I was very reluctant, to say that it would be okay to let me help a stranger who had not had a holiday, who knew that let me help a stranger who had a holiday with me, and it was his fault in the first place.

Dealing with strangers, I am really annoyed by a slight social phobia.

"If you don't help him solve his stand-in, his stand-in will find you trouble sooner or later, you don't like people to trouble you, right?" The tone was flat, but with a hint of threat.

If there is Baishi, it will be easy to do, his big personality must be very good at dealing with strangers, and then call He Jinyan and Zhao Huanjue, one intelligence persuasion and one force persuasion, even if it really doesn't work, there will always be a way to do it.

"Can you find a few more people to work with me on this?"

"Of course, as long as the purpose is achieved"

"Purpose?" I saw that his tone became more and more gloomy, thinking of all the things that might happen in the future, it was better to be cautious, after all, he was only with me, why should I trust him?

"Don't worry, I'm not asking you to do dirty things, that person doesn't belong to this world in the first place"

"He should return to his own world, Twilight Bookmark" "Alfalfa" handed me the suspended bookmark.

"Make Good Use of Its Power"

I took the bookmark, and when my fingertips touched its surface, I felt an indescribable feeling, after all, it saved me once.

"It's called... Twilight bookmarks? ”

"Alfalfa" nodded, and transformed into a series of white bubbles, expanding more and more until they reached the maximum, and when the bubbles all burst, I could no longer find his shadow.

In the morning, when I was eating, I saw the news that was being broadcast on the TV. "The latest broadcast of the TV station, the city has been a traffic accident for many days, according to the investigation of the traffic police department, it is suspected that someone did it deliberately, let's watch a post-incident interview about the injured person in a traffic accident on Nanhui Road"

"I don't know what's going on, the engine got into the water, I parked the car in the garage when it rained, it couldn't have been watered?"

Nan-e Road? How do I remember witnessing a car accident there? It can't be such a coincidence, right?

"Xiaopu, there is smog outside today, slow down when you go out" My mother told me when she went out, and the prepared breakfast was set on the table.

I opened the curtains and looked out the window, and the scene outside was indeed a gray expanse, swallowing up all the buildings.

Thinking that the haze weather is very delayed, I better hurry up, who knows if I will run into a traffic jam.

In fact, the haze weather is also a good thing for me, at least there is no need to wrap myself like a dumpling before going out, such weather is estimated to have a lot of people wearing masks, and no one will notice my abnormality.

I ate the bread slices and ham sausages at a breakneck pace, got everything I was going to take with me, went back to the table, got a bag of milk, and went out.

Entering the elevator car, after pressing the button on the first floor, my eyes were fixed on the selected button, I didn't dare to look at the mirror opposite, and I always felt that something bad would happen to the elevator in such a closed environment.

"Sa-" A gust of wind blew through the crack in the elevator entrance. I didn't pay much attention to the wind generated by the elevator when it landed, but my eyes looked in the direction of the mirror.

It doesn't matter if you don't look at it, something will happen when you look at it. I saw a dark shadow appear behind me in the mirror, and after three or four seconds, it disappeared.

My heart "chuckled", I shouldn't have looked in the mirror so much, it couldn't be the warning given to me by the man in my dream, right? deliberately conceals his appearance, and he is not a good person when he thinks about it.

"Ding-" The prompt sound to the first floor finally sounded, and I flew out, not daring to stay in the elevator car for a second, but at the same time as I rushed out, I caught a black shadow and rushed out with me.

I rubbed my eyes and looked around to see that there was no one around, where did the shadow come from? It must be a hallucination caused by my wandering mind, yes, fake, it's fake, it's not enough to study, I'm not busy enough, and so many bizarre things still pop up out of thin air.

Fortunately, I walked early, and I managed to get on a bus with a relatively small number of people, but I didn't dare to sit in a single row of seats anymore, and changed to a double-row seat area.

I put on my headphones as usual, cut off from the outside world, and look out the window at the scenery, if the journey is as usual, it will be lucky.

The sound of music made me a little confused, it should have been a cloudy day, and the lights on the car gave me the illusion that it was night, and I almost fell asleep.

I can't sleep, and it's miserable if I sleep too much! I woke up immediately and looked out the window, but luckily it was still some distance from the school. The bus drove slower and slower and stopped, and I didn't know what was going on in front of me because the smog was too thick, so I guess I was waiting for a red light.

But after waiting for almost three minutes, I didn't see the driver driving, and at that moment, I heard the sound of police cars and ambulances.

Got into a car accident? With the help of the high beams, I could barely see a person in front of me, and a blue and red light hanging from my right arm.

The man motioned for the driver to take a detour, and the window facing the seat I was sitting in happened to have a close view of the crash scene, and I vaguely saw two worn-out cars on the road, and a group of paramedics were carrying the injured person onto a stretcher.

It's really miserable, it seems that today's traffic police and medical staff have been busy enough for a while.

When I entered the classroom, only a few of my classmates who lived near the school had arrived before me, and they were all busy around the bookshelves in the back door.

"What's wrong?"

"Xiaobai, you're here, a bookshelf has fallen down, and we're about to pull it up" Ah Jue squatted on the ground and picked up the books scattered all over the ground, and pointed to the bookshelves that fell to the ground with one hand.

I also came to help pick up the books, but I was puzzled, how could the bookshelves be made of iron? Usually, there are classmates fighting in the back, and they don't see the bookshelf over.

"This bookshelf fell when you came?"

"yes, I saw a few of them packing up when I came."

A classmate said: "Today it was my turn to be on duty, so I came a little early, and when I opened the door, the bookshelf was clearly standing there, so I went to the water room to wash the rags, and when I went back, I heard the sound of something hitting the ground, and then I saw the bookshelf falling."

"The wind blows?" Ah Jue pointed to the wide open window, and the upside-down bookshelf was also very close to the window.

"How much wind does it have to blow the bookshelf over? There are no typhoons today," I gave him a blank look.

"This bookshelf is a bookshelf with ideals, and I learned to fall down by myself," Ah Jue said serious nonsense.

"It's obviously a bookshelf that has lost its ideals," I gave him another blank look.

"Let's quickly pull up the bookshelf, the books are almost organized," said one of the students, who was about to pull the bookshelf.

We pushed hard in different directions, and it was okay for five boys to pull an empty bookshelf. "One, two, three! Pull it up! "The corner of the bookshelf is some distance off the ground, and it can be pulled up with this force.

"One, two, three! Pull again! "Again, we worked together, and the shelves were gradually becoming perpendicular to the floor." A little more effort! Right away! Ah Jue's face was already red because of the exertion, which was really reminiscent of a red light, or a monkey squatting with his back to traffic on a broken red light.

"Poof!" I couldn't hold back my laughter for a while, and I guess they all thought of the "wonderful" picture and snickered. Ah Jue didn't know what to do, saw us laughing and asked why we were laughing, and after a few seconds of reaction, he became angry, "What's ridiculous! That's it when I'm hot! ”

"Look at it, it seems to be a little redder than just now"

"Guan Erye"

"It's more like sticking a mustache"

"It's going to be weak when you laugh! Not afraid to smash your hands? Seeing that he was about to "smoke", Ah Jue quickly changed the topic.

"Okay, good, let's work hard again, and we're about to straighten it out" We stopped the desire to laugh in time and worked hard together, "Bang! The bookshelf was firmly pressed against the wall.

"It's good to put these books back in their place, but luckily it's not the personal bookshelf, or we don't know how to put them" I'm in charge of the books below, and Ah Jue is in charge of the bookshelf above.

Soon I noticed something unusual, "Personality" and "Face and Stage" had four or five black scratches on the covers of the books.

"Did these two books have scratches?" I took the book and asked my classmates who were mopping the floor next to me.

"I don't think so, every day I have to be responsible for the placement of literary shelves."

As we spoke, Ajue's voice came from above. "Look at what I've found? Did our class sneak in with cats? ”

"Cats? But the only common animal in our school is the Dalmatian raised by the doorman? The classmate I was talking to said.

"Common animals include cockroaches, bed bugs, and mosquitoes," I said, and stomped a passing cockroach to death through the paper.

"It must have been done by a cat, otherwise how could there be scratches on the bookshelf? Can't a dog jump up? ”

"Scratches, you say? Is it black? I motioned for Ah Jue to come down and look at the traces on the book.

At this time, the corridor gradually became lively, and many students who were studying and living in the dormitory walked into the teaching building one after another. A group of people came in through the back door, interrupting our conversation.

"Yo, it's so early! What kind of fame do you have in the class? ”

"What can I do? The bookshelf is down and we just pulled it up."

"Okay, okay, then I'll mop the floor, I don't want the head teacher to catch me fishing"

After the classmate left, I repeated what I had just said, "Are the scratches you see black and very thin?" ”

"yes, but what cat can scratch black scratches?"

"Maybe if you get rid of the paint on the outside of the bookshelf, you'll be able to reveal the color inside," I tried to think in a reasonable direction, and never let me run into those strange things again.

"Maybe yes, I forgot to erase the blackboard yesterday, and the math formula is still there, so I wiped it."

Ah Jue hurriedly ran, I returned to my seat and took out the homework to be handed in and the textbook for the morning self-study preparation, my mind was still thinking about the black scratches, and I couldn't help but think of what "Alfalfa" had said to me.

"If you don't do it, strange things will come to you one after another."

Why did he speak to me in that semi-threatening tone? I could even hear his restlessness, and what was the purpose of the "Twilight Bookmark"? Why make good use of it?

These are all things that I don't know, so let's wait until after class to discuss with them what "Alfalfa" told me.

"Please look at the contour topographic map on the screen, the map on the screen is the same as the one on question 3 on page 46 of your workbook, students who can't see clearly can read the workbook"

Although I sat in the "golden zone" in the middle of the classroom, my eyesight was really not very good, and I still couldn't see the numbers marked on the contour line.

Page 46, Question 3 Found it, the terrain should be a valley" Just in case I asked the number marked on the screen of the same table, "Tian Yuan, can you help me see if the number marked in the center of the circle in the lower left corner of the screen is 500?" ”

"I'll take a look, isn't it, 538" Tian Yuan looked at my workbook, "Huh? Why is 500 in the workbook? ”

"The picture on the screen is scanned from the exercise book, right, it should be the same?"

"The teacher should be scanning the old version of the teacher's book" Tian Yuan carefully looked at the string of small words in the upper right corner of the screen, which was marked as the seventh edition, and we used the eighth edition.

"Do you want to tell the teacher?" I saw that the teacher was coming to the row where I was, so I quickly raised my hand in advance.

The teacher noticed my movement and walked over quickly.

"Pu Shaohan, is there any problem?"

"Teacher, the contour numbers in the workbook are different from those on the screen? The center of the circle in the bottom left corner of the screen"

"Different? I'll take a look," the teacher lifted his eyes, "500." The teacher glanced at my workbook, and the number 500 was also marked on it.

"That's right, it's all 500"

"No, teacher, I just saw that the number on the screen is 538," Tian Yuan testified for me.

The teacher glanced at the screen again, "How did it become 547?" The teacher touched the thinning hair on the back, a little confused.

"Forget it, people are old and their eyes are not good" The teacher shook his head and said loudly to the class: "Students, take out the workbook, we take the workbook as the standard, the picture on the screen is different from the workbook"

After class, I couldn't wait to find Shiraishi. "Brother Bai, what is the number you see in the center of the circle in the lower left corner of the contour topographic map on the screen that the teacher showed us in class?"

"I want to think about it... It seems to be 538"

"As I saw, the teacher didn't believe it at first"

"But after a while, it became 500 again, and it became 547 again, and it changed all the time, am I dazzled?"

"There are too many harmful particles inhaled today to cause collective dazzle, and there is nothing wrong with it"

"Brother Pu, what's wrong with you? "Shiraishi touched my forehead, "No fever?" ”

"you!" I'm going to go back.

"Hey, hey, wait, I'll leave early after school tonight, there's something going on at home."

Sure enough, as soon as this guy heard the bell of the last class, he rushed out of the classroom, and tonight I went along with Zhao Huanjue and He Jinyan.

I accompanied them to the flagship store opposite the school to have a look, and on the way, I habitually took out my mobile phone and swiped the "circle of friends", but I didn't expect to brush my mother's dynamics.

"Who knows what this thing is?" The accompanying picture is a long wooden strip with a blue tassel attached to the end.

Isn't this a "twilight bookmark"? It's just that the color of the tassel at the end is different from mine.

By the way, I have long wanted to ask He Jinyan about the bookmark, but I can't take care of it so much now, anyway, I have to pull them in the future.

"Drill, see if you have one?" I zoomed in on the picture on my phone to show him.

"You say this? On the day of the exam, I'll tell you, it's weird! I wanted to tell you, but we went home on a different route."

"I was packing up at the end of the exam, but suddenly I lost consciousness, and when I was relieved, I had this extra thing in my hand."

"The next day, I also saw the characters in your work running around the school, I guess I hit the shirt, right?" Ah Jue looked particularly flustered.

"I saw it myself, you didn't look away, you didn't hit the shirt, I'm sure the one running around the school was the character I created"

"Your character was still on the bus, and I bumped into you," I said faintly.

"Don't come here!" The drill bit and Ah Jue hugged each other.

"What the hell! You're men! Male! When did it become the same as a group of gossip girls with them! What's wrong with haunting? Physical Excess! I yelled at them, and I came back to my senses.

"By the way, there's something I'd like to discuss with you, you... Will you trust me? ”
