Silver-gray aluminum alloy balustrades, white walls, marble floors are smooth enough to illuminate people, and the wide lecture hall corridors are neat and long. A long table discussion on the paths of divergent particles after a closed chord collision has just come to an end, and the intermission is filled with people coming out of the front and back doors, alone in finding some tea for their cups, or talking in groups of three or two. The last one to come out was Tang Jianyu, who was holding a booklet, he looked at the door, came to the side of a brazilwood tree in the corner alone, looked at the stretch of grass outside the window, and frowned.

The climate was pleasant, the weather was sunny, and her eyes were full of deep shades of blue, like the color of the dress she wore that dinner. I almost made a mistake when I spoke just now, and I also represented the entire A University research group, thinking of this, Tang Jianyu couldn't help but shake his head quickly, eager to get rid of the impact of that dinner.

"Thanks to you, I wouldn't have noticed her." Zhang Kun said that the look of gratitude in his eyes was shocking to Tang Jianyu, so much so that it came to his mind thousands of times later, and every time he felt suffocated. He let out a self-soothing breath, reached out and pinched the bridge of his nose hard, and said to himself, "I can't think about that yet. ”

"It's a little tiring, four or five hours without stopping." After the deep voice, a hand fell on Tang Jianyu's shoulder, and he looked up to see an elderly man with an elegant face, who was one of the organizers of the seminar. Tang Jianyu hurriedly straightened his posture, greeted the other party, and said, "I'm not tired, my eyes are a little swollen and painful, maybe the lights in the examination hall are too strong." Hearing this, the organizer put one hand in his pocket and said, "Several people said this, I'll find someone to adjust it," and said with a smile: "Speaking of eyes, there are more than 20 math people on the table, except for you, none of them don't wear glasses." ”

Tang Jianyu smiled cooperatively, "It's really true when you say that." The organizer looked at the promising junior in front of him with a tall posture and a handsome face, and sighed: "The paper you published in the second volume of Acta four years ago, on the paper on demonstrating the existence of invariants in low-dimensional manifolds, has inspired the domestic mathematical community to this day, and you are the only Chinese mathematician who has been signed, and you are still so young!" The excitement of the seniors made Tang Jianyu ashamed, and he waved his hand again and again and said: "That article is led by my teacher." The organizer had an idea, "Oh, yes, your mentor at the Paris Institute is also Swede. Tang Jianyu corrected solemnly: "It's Swiss." ”

"Oh oh, haha, yes!" The older man laughed heartily, "Their research community is really full of flowers, and we are dizzying!" Tang Jianyu heard the taste in his words, nodded first and shook his head, and said: "With a leader like you silently cultivating new generations of newcomers, our mathematics will definitely usher in the day when it shines." "Hey, theoretical mathematics is high and low!" The organizer nodded heavily, looked up in response to the brilliance in the young scholar's eyes, and said, "Hope is in people like you. ”

The high-intensity study lasted for two weeks, and Tang Jianyu, who returned to City A, was almost exhausted, and he had been sleeping in the car from the time he got off the plane to the time he went home, and he didn't hear the assistant even make four phone calls. "I'm back, I'll be in the office tomorrow, is there anything urgent?" Tang Jianyu put down his luggage before he called and asked, and the young woman said: "Just confirm whether the teacher has come back, I went to clean the apartment in the town yesterday, and you put the materials you will use next week on the bookshelf over there." ”

After Tang Jianyu thanked him, he asked, "Are there any letters from me, invitations or the like?" The female assistant replied affirmatively, "There is only one letter of request for "Mathematics Education in China." Tang Jianyu closed his eyes and opened them again and said, "Okay." "However, I haven't been to the office of the town middle school in a week, so it may not be possible to send it there." Tang Jianyu didn't answer, and the female assistant tentatively added, "Is the person close to you going to do a happy event, teacher?" Tang Jianyu took a breath and said lightly: "I want to take a break, wait for me to contact you first." The female assistant was stunned when she heard this, and let out an "oh" in a curt.

Stale black-tiled red bricks, long cement corridors, and unknown light cast silhouettes of tall metasequoia onto mottled blackboards with chalk written notices for Friday's school cleaning. Tang Jianyu followed the sound of a row of faded wooden doors, and the sound of machines roaring constantly came from the door: this was an old-fashioned photocopying room used to mimeograph test papers.

A strong convection of air ran through his body, each roaring into the distance, "Whoa! "The room was full of white paper, like frightened butterflies. At this moment, the wooden doors, walls, and even the ground were all gone, and he was suspended in the deep darkness with a roaring mimeograph machine, and snow-white pieces of paper were still flying out. Tang Jianyu wanted to speak, but he couldn't make a sound when he opened his mouth, and he walked in the direction where the paper flew from.

The old paper-covered machine whimpered endlessly, beckoning the man to move closer to it. The pieces of paper invaded Tang Jianyu like a white dove that grabbed food, making it difficult for him to walk. The white paper was piled up in front of the man into a small hill, and he peeled through the layers of paper, and found that there were words written on the existing paper, and the closer he got to the mimeograph machine that made the sound, the denser the words became.

The paper flew over his head like a flock of migrating birds. He looked up and saw that every imprint on it was familiar: the topics he had discussed in graduate school, the papers he had taught his students, and the many pages of math notes he had written by hand in a blue notebook......

He seemed to touch the corner of the mimeograph machine, and the roar immediately stopped, and the hill of paper suddenly collapsed, and a white color scattered in all directions...... Before his eyes was a little girl in a white dress, no bigger than his armpits. When Tang Jianyu stretched out his hand, the little girl turned around first.

She grew up quickly, and soon grew taller than a man's shoulders and grew into a woman. At that moment, the darkness behind her spit out a dazzling halo, revealing the long corridor full of wisteria in the village elementary school. Her face was covered with a white veil like a bride, and she was silent, but her shallow eyes saw Tang Jianyu's heart.

Tang Jianyu was shocked, he knew her, this was his bride! Once upon a time, she was veiled around his arm, and he almost saw her face! This time, he must see her face before the principal asks him to print the midterm exam papers! He lifted his feet to run towards her, to unveil her.

But at this moment, the darkness under his feet suddenly broke, and he fell on his back.

"Don't leave me behind!" The woman lay at the end of the hallway, yelling at him. In the flying white veil, Shi Jiaojiao's panicked face was revealed. Tang Jianyu, who was falling, stretched out his hand upward, his mouth opened and closed, but he still couldn't make a sound. watched as her face fused into a point of light with the wisteria flowers flying behind her, and was engulfed in chaos......
