Early Monday morning, fog was thick. School buses line up and move forward slowly. From a distance, it looks like a giant python cruising through the deserted streets.

In a school bus, Mo De looked at Wu Fan, who was pale and disgraced in front of him, and sighed helplessly.

"Hey, Fat Wu, don't spit on me if you really want motion sickness." Next to Wu Fan, Ji Keqing, who was tied with a golden double ponytail, clasped his hands to his chest, and shrank by the car window with a frightened look, for fear that the fat man next to him would harm the pond fish at that time. "It's not enough, why don't we change?" Turning his face, Ji Keqing asked tentatively.

"Forget it, this one next to me can't stand the toss." With Mo De's fingers, Ji Keqing found that Su Ziwen behind him was not asleep, but curled up in the seat, his face was also pale, cold sweat, his eyes were staring at his toes, covering his mouth with one hand and holding his abdomen with the other to support him.

After Ji Keqing threw a "sympathetic" look at Mo De, he sat back on his seat honestly as if he was fated, and his every move was quiet and light, for fear of detonating the two time bombs around him.

From Tianshui High School to the center of Qin, it is usually only two hours away, but it was delayed for half a day due to heavy fog. By the time we arrived at the target hotel, it was already close to lunchtime.

Ji Keqing hugged Su Ziwen and had to carry Wu Fan, and the two of them first sent their companion who lost half his life with motion sickness back to the room to rest. Wu Fan's recovery ability can be called first-class, and he smelled the fragrance at lunchtime, and dragged Mo De all the way to the canteen with his eyes shining. After inhaling a storm, he patted his stomach and said comfortably: "Dude, this wave of blood is resurrected!" ”

"I can't imagine that you fat man looks tall and big, and you can get motion sickness." A sound of laughter came from behind Wu Fan. Ji Keqing came over with Shi Shiran, a dessert cake after the meal.

"What's wrong with motion sickness, isn't the class leader also motion sickness? With the squad leader, I am glorious, I am proud! "The fat man is a good player in this regard.

"How's the squad leader?" Interrupting Wu Fan and Ji Keqing's bickering, Mo had to interject and ask.

Ziwen was still unwell and had already fallen asleep. I'll bring her some food back to her room later, and I'll eat it later when she wakes up. Ji Keqing glanced at the fat man Wu who was making a grimace with his eyebrows fluttering, and replied to Mo De's inquiry.

......

At half past one in the afternoon, Mo De saw the meeting point from a distance, Su Ziwen was holding the bag and eating quickly, while Ji Keqing was waiting with an apologetic face holding a water cup and a tissue. Before Mo had to get closer, he saw that the two girls quickly exchanged objects in their hands, Su Ziwen picked up a tissue and wiped his mouth, and then handed it to Ji Keqing along with the packaging bag, tapped his chest and took a few mouthfuls of water. Ji Keqing, who took the bag, walked away quickly, threw the bag and paper towels in his hand into the trash can, and then hurried back.

"What's the matter, it's late?" Wu Fan held back a smile and deliberately asked Ji Keqing.

"Shut up, dead fat!" Ji Keqing, who poked the sore spot, gently patted Su Ziwen's back to help her calm down, while glaring at Wu Fan like a fried kitten. After returning to the room with lunch, Ji Keqing saw Su Ziwen sleeping soundly, and wanted to let her rest for a while before getting up to eat, but she didn't expect that she would also fall asleep in a daze. The two were woken up by the preset alarm clock on their mobile phones, which caused Su Ziwen to fall into the dilemma of eating on the spot.

"I'm fine." Tightening the water cup and putting it back in the schoolbag, Su Ziwen raised his hand and patted Ji Keqing's shoulder, signaling that he was fine. Ji Keqing was also slightly relieved when he saw this. Wu Fan on the side squeezed his eyebrows even more, and the angry Ji Keqing pounced with his teeth and claws.

"Let's go, Old Joe is over there, let's hurry over." Don't hurry out and play the round.

"Let's go, don't be late." Su Ziwen spoke up again, and the two people who were chasing after him also stopped. The group of four rushed to the entrance of the Guizang Museum.

Standing in the column, the group listened to the patience of the tour guide and the general information of the collection behind them.

The word "return to Tibet" is taken from the "Returning to Tibet" chapter, one of the "Three Changes" of the old calendar, and also contains the meaning of "collecting treasures". There are several collection museums all over the country, which have relatively complete records of the old calendar and the history of the new calendar, and some of the collection museums also preserve some cultural relics for exhibition.

Under the command of a number of tour guides, Tianshui students marched towards the museum in an orderly manner. The moment before entering the door of the museum, he raised his head and glanced at the black plaque above his head that carried the three quaint characters of "Guizang Museum", and he couldn't help but remember what the man had said to him.

"There are some things, even if you can't see them with your own eyes, just seeing the fragments of it is shocking enough."

The dark corridor was not long, but it was exceptionally quiet. The chaotic footsteps around him could not hide the nervous beating of the young hearts that gradually accelerated.

One step into the light, everyone will lose their mind and stay for a while, and then continue to move forward under the gentle guidance of the tour guide. But everyone's eyes were staring at the floating light and shadow in mid-air, and they couldn't take their eyes off.

It is the epitome of the once blue sea and blue sky, the running and jumping of hundreds of millions of birds and beasts, and the light and shadow projection of the once glorious and dominant human civilization in a small corner of space.

It's so beautiful that it's dizzying, it's so beautiful that it's fascinating, and it's so beautiful that it brings tears to your eyes.

That magnificence, that surging vitality, is too shocking for this group of students who have barely walked out of the security realm of Qin City since they were young.

"According to the old calendar, human beings originated from an ancient creature called 'Forest Australopithecus'..."The gentle voice of the tour guide lady sounded quietly, slowly pulling the shocked people back to reality. The emergence of human beings, the germination of civilization, the evolution of instinct, the birth of consciousness... With the explanation of the tour guide's sister and the literature and pictures on both sides of the passage, everyone seemed to have witnessed the evolution of human beings and the development of civilization.

From the control of fire, to the use of tools, to industrial reform, human civilization began to explode in the last millennium. Electrical, mechanical, biological, intelligent, quantum... The unbridled human civilization seems to be trying to break free from the shackles of the blue home planet. The curvature engine has been successfully designed, and the structure of the Higgs boson has been preliminarily explored by matter analysis... The fire of civilization is burning, as if it wants to swallow all the bumps in the road, burning this fire into every inch of human vision.

"When human civilization climbs from the peak to a higher peak, the old calendar is quietly coming to an end, and a change opens the prelude to the new calendar." There are still unknowns waiting to be explored, but the young lady who led the tour stopped in the atrium and smiled at the children who were still addicted to the explanation: "This is the end of today's visit, and we will arrange the rest of the content to explain to you one by one in tomorrow's visit." ”

The group walked out of the atrium corridor, and everyone was silent on the way back.

When you step out of the Gui Collection, you will find a small square. Mo De only felt a little dizzy in his head, as if the tiredness accumulated from surprise, joy, and nervousness all the way came to his heart. Shaking his head, Mo had to turn around and look behind him, only to see that everyone's expressions were tired.

"Mother, I don't think I'm going shopping, but I'm really tired buddy..."Regardless of the image, Wu Fan sat on the square with his buttocks, took out a towel to wipe his sweat.

"Whew... Morde... Why are you acting like you're nobody..."Zhuo Cheng, a member of the study committee, stomped his feet and moved his calf and calf with slight cramps, while taking out his glasses cloth and wiping the lenses, looking at Mo De and asked.

"Maybe it's my stamina." Touching his nose, Mo De replied with a sneer.

There was once a man who, when he was a child, babbled on and on about the glories of that old time.

It's just that when talking about this, there is no yearning or excitement in the eyes of men, and there is only a faint loneliness and a little remembrance.

"Let's get up when it's almost time to rest, and the next shift will be coming soon. After you go back, pay attention to rest, tomorrow morning's study visit may be more tiring..."The tour guide helped the students who collapsed to the ground one by one, and her sweet voice was soft and soft, with a smile.

"Turtle turtle, buddy still plans to continue to be hi at night..."Wu Fan got up and left the word "human" in place.

"Let's go, don't think about what you don't have, although tomorrow's visit is an event in history textbooks, but with the projection simulation technology in the museum, it is estimated that it will be extremely exciting." Mo had to take Wu Fan by hand, and then glanced back at the people in the square. The half-day visit is really not a short journey, but everyone is attracted by the light and shadow in front of them, and they completely forget about their fatigue during the visit. A few guys in the class who have good physical strength are also prostrating at the moment, and they should have received a lot of information in a short time, and their minds are quite consumed. However, Su Ziwen, who was thin and thin, was as usual at the moment, there was still no expression on his cold face, and Ji Keqing, who was trembling with his calf, walked towards the exit.

"Tsk, it's really unseemly... Let's go, hurry up, hurry up. He muttered in a low voice, and had to beckon the fat man to return with him.

......

The signal switched lights, and the tremors on the sleepers intensified, and the roaring sound came from far and near. "The D21 train is about to enter the station, please stay away from the platform..."

The dust and smoke stopped, and the doors opened. A tall figure walked out with a small flow of people. Standing on the platform, Mu Qing flipped out his mobile phone and checked the destination he would visit tomorrow.

"Qin City, Gui Zang Museum."
