The next day, Shi Yi and Hongyu visited some famous tourist attractions in Xi'an, Shi Yi looked at these places of interest in the crowd of tourists, there was always a sense of familiarity, but she didn't remember it very clearly, in her impression, when she was a child, the memories of those past lives were still like a few treasures, but slowly with the passage of time in nursery classes, elementary school, and junior high school, all the relevant memories of the past life gradually faded, almost blurred, and then thought about it, it was more like a very strange dream. If it weren't for the fact that after so many years, she repeatedly told herself "I want to see him", those memories of King Nanchen would have been destined to disappear without a trace.

On the last day, the two of them were even more tired than going to work, and on this last day, Shi Yi and Hongyu were both lying in the hotel, resting and sorting out the work materials back. She took the sorted materials to the hotel front desk to print. The little girl at the front desk heard her request, but she was very polite and took the USB flash drive: "May I ask which room are you from?" Once printed, I'll have the staff on the floor send it to me. "Thank you, room 888," she said as soon as she finished speaking, and felt that something was wrong, "Forget it, I'll just wait here, don't copy it, just print it out." "Room 888?" When the little girl heard the room number, she quickly asked, "Miss Shi?" "Yes." "There's a book of yours here, which was brought over by a gentleman just now, and I haven't had time to deliver it to you," the little girl picked up a large brown paper envelope from the side and put it on the counter, "The gentleman said that his surname was Wang Chen," and after speaking, the little girl muttered cutely, "This surname is really strange, it seems that there are no surnames in the hundred families, only the surname Wang." Shi Yi ignored it, just continued to look down at the envelope, which was without any handwriting, and thought, "Did he just leave?" "I tried the weight and feel, and immediately thought that it should be a book, could it be a city note?

The little girl took the USB flash drive and motioned to the people around her to help take care of it, and walked out of the counter herself, "If the document is very important, the guest can operate and print it by himself, Miss Shi is here, please." Shi Yi was already a little uneasy when she heard Wang Chennan's name, and the little girl opened the document and began to print; Shi Yi didn't say anything to the little girl, just looked at the envelope and was distracted. When he printed out the information he wanted, he said thank you and walked away with the information, got on the elevator, and opened the envelope when he returned to the room, and saw that it was indeed the book he had said in Qinglong Temple. The pages of the book are not very new, and the cover has some signs of wear, it looks like someone else really showed it to him, and there is a blue sticky note on the title page of the book: This book was given by a colleague from the research institute, if you like it, you don't have to return it - Wang Chennan.

The handwriting is beautiful, but it is different from what Shi Yi remembers. She looked at the note over and over again, and couldn't help but send him an email, asking him if there was a landline in the lab, so it was convenient to call. After the email was sent, she opened the book and found that some pages were pasted with white sticky notes by him, which were simply marked with different views from those introduced in the book. If it's a place to eat, there must be specialties that you think are delicious; Shi Yi knew that this must have been written by him a long time ago, not for himself. But looking at the "exclusive notes" pasted on this city notebook, I still can't help but think that he didn't take these sticky notes, probably for his own convenience.

She glanced at the QQ mailbox, which had already received Wang Chennan's reply email. There are still no superfluous words on it, just the same conciseness, just a string of numbers; Shi Yi picked up his mobile phone, entered the numbers, coughed lightly twice, and finally dialed his phone after letting his voice sound the best. The phone went through, "Got the book?" This is the first thing Wang Chennan said after receiving the call, "I got it, thank you" She just wanted to call Wang Chennan, but she really connected, but she didn't know what she wanted to say next, "This book is okay, it's not like other books like a travelogue for publishing money, and I write a personal lyric at length," Fortunately, he didn't have a cold scene, and naturally explained to Shi Yi, "It's not like a lot of city introductions, most of them are soft advertisements." She snorted, "Okay, I'll take it seriously." ”

Counting, this is the first time the two have talked on the phone since they met. The two of them talked about yesterday's day trip to the day before yesterday's day trip to Qinglong Temple, and in the end, Wang Chennan first proposed the end: "I seem to be about to start working." "I've always wondered what the institute is like," she said cheekily, "can you show me it?" Hongyu, who had been eavesdropping beside her, immediately glared at her and said, "Can we be more reserved?" She pouted: Am I just curious, Ruby rolled her eyes, shook her head and sighed and laughed. "It's boring" Zhou Shengchen seemed to refuse, but after a pause of a few seconds, he continued, "But you are lucky, today is Sunday, most of the researchers are on vacation, and there is no problem with taking you to see it." She quickly said yes and wrote down the address Wang Chennan said. He finally said, "When you get to the door, you still call this number, and I will go downstairs to pick you up." After Shi Yi hung up the phone, he rushed into the bathroom with a makeup bag. Hongyu jumped out of bed, chased barefoot to the bathroom door, and looked into her eyes through the mirror: "Can you tell me what is it about him that attracts you and makes you like it so much?" ”

Under the yellow-orange-orange light, she was using makeup cotton dipped in makeup remover, and thoroughly cleaned her face in the mirror, her movements were careful and meticulous, completely exposing her anxiety and expectation, and when she was completely cleaned, she turned on the faucet and looked back from the mirror very seriously: "I think I must have known him in my last life, and I owe him a lot of debt." Hongyu smiled: "It turned out to be the fate of the past life and this life." She pursed her lips and smiled, not to mention that she was in debt. If he remembered a little, would he not want to see himself? After getting into the taxi, she showed the driver the text message sent by Wang Chennan, and the driver immediately laughed, saying that she had just taken a man from here an hour ago, and he was very familiar with the road. Shi Yi had already guessed who the driver was talking about, but he didn't expect such a coincidence. This road is not far, Shi Yi got out of the taxi, and as soon as he took out his mobile phone, he first received a call from Mr. Wang, and wanted to discuss the next work with him. Wang was always a workaholic, and she didn't dare to interrupt easily, so she had to pace back and forth aimlessly in front of the plaque of the Xi'an Branch of the Chinese Academy of Sciences, talking on the phone. However, Shi Yi is not so enthusiastic about work, but she does not delay her work, and she has a good relationship with everyone in private, and Mr. Wang often jokes with her; "Yesterday, my younger brother Wang Wen was still asking me, have you been supported by someone a long time ago, so you are so uninterested in money, fame and fortune. At that time, I laughed badly, so I told him that we Shi Yi had a decent face, and it must be justified to marry," Mr. Wang finished talking about business and began to gossip with her, "Shi Yi, tell the truth, did you marry an incognito rich man early?" Otherwise, why do you play outside all year round, and if you don't take the job, you won't take it? ”

Shi Yi lowered his head, walked slowly step by step, and said with a smile: "I'm not interested in rich people." Mr. Wang laughed: "What kind of do you like?" Tell me, my sister will keep an eye on you. Her gaze drifted through the half-man-high closed door, and saw a figure already appearing in the empty open space in front of the building. He walked very fast, coming in her direction from far to near, still wearing a very handsome suit, but with a white coat on the outside, he should have just come out of the laboratory, when Shi Yi saw him, Wang Chennan seemed to see her too, raised his right hand, and pointed to the closed small door next to the door. Shi Yi looked at him, nodded quickly, and ended the conversation on the other end of the phone: "The person I like must be a professor, preferably a researcher in polymer chemistry." She whispered, like a joke. What did you say? What professor? Mr. Wang was taken aback. Don't talk about it, I'll call you in the evening. She saw Wang Chennan approaching, busy closing the line, and ran to the small door.

Here, he seems to be very different from usual, there is a feeling that he can't speak, and he looks a lot more rigorous, "When did you arrive?" He asked her as he took out the register from the small window of the security room and signed his name and time, "Did you bring your ID card?" "Bring it." She looked down and pulled her ID out of her bag and handed it to him through the railing. When all the procedures were in place, someone in the security room opened the door and let her in. Sure enough, as he said, because it was a weekend, there weren't many people moving around. The two of them walked all the way, and occasionally someone passed by, greeting them with their chins bowed, and did not talk too much. Shi Yi was infected by the quiet environment here, and even walked a little cautiously, but helplessly wearing high heels and walking on the marble floor, he couldn't avoid making a sound. The more vocal, the more careful; The more careful you are, the louder it appears.

"Female researchers here also like to wear high heels," he said, pausing outside the double-glazed door, typing in his password and fingerprints, "You don't have to worry too much." She bowed her head and smiled embarrassedly, Shi Yi thought to herself, "How does he know what I'm thinking, is it because I have a heart, or am I showing it on my face?" After the glass door was decrypted, he reached out and pushed it open, and led her past many opaque glass rooms, and finally stopped outside the office; It wasn't until he pushed the door and entered the closed room that Shi Yi was finally relieved: "I always feel that entering this kind of scientific research institution is like stealing state secrets." "So what?" He smiled and sat behind his desk, "Isn't it disappointing?" "Disappointment doesn't count," she snorted, looking around his office, "The smell here is still very special, what do you usually do?" I mean, what kind of experiments are you going to do? "Halogen-free flame retardant silane cross-linked POE composites." Except for the last four words "composite materials", I didn't understand them; She silently pointed to the blank paper in his hand: "Can you write it to me?" The words you just said. Wang Chennan had nothing to do, took out his pen and wrote these words; Shi Yi looked at the paper and was silent for a while, still puzzled: "Is there a simple way to try to make me understand?" Wang Chennan thought for a while: "Simply put, it is made of outer wire materials, corrosion resistance, high temperature resistance, aging resistance, flame retardant, etc., understand?" He smiled slightly. Understood" Shi Yi thought about it carefully and couldn't help but smile, "But as soon as you explain it like this, it immediately seems very untechnical, doesn't this kind of thing already exist?" "It's almost, but it's basically the technology of more than ten years ago, and there is still no big breakthrough in the world, so whoever makes it first is a leap of more than ten years" Wang Chennan handed her a small bottle of pure water, "For example, now in China's first-tier cities, most of the outer layers of wires have been aged, and about 80% must be replaced, which is a very large consumption." If current technology can go one step further, it can extend the lifespan, even if it is an extra year, which is an astronomical amount of huge revenue. ”

Shi Yi sighed and looked at him: "With such an explanation, it has become great again." She was about to continue asking, but suddenly there was a knock on the office door. Wang Chennan said come in, and the door was immediately pushed open from the outside, Jiang Xiaoye probed in, and smiled a little proudly: "Sure enough, Sister Shi Yi is here." She was a little surprised and a little embarrassed: "How do you know I'm here?" "We all have cameras in our laboratory, and when I came back from outside just now, I heard a few senior brothers saying that Teacher Wang Chen brought a big beauty, so I guessed that it was you, sister." Shi Yi thought to himself: Camera? It's really a very strict access control. Wang Chennan snorted amusedly: "So what? "So," Jiang Xiaoye said with a straight face, "Teacher Wang Chen, you have worked hard with us, everyone wants to invite the teacher to have a light meal tonight, and entertain the guests by the way." ”
