"Oh, we're classmates." Li Guanghan lowered his head and said, he answered a little flustered, pretending to tidy up his soaked clothes, obviously avoiding Chen Aili's gaze, looking lacking in confidence. This aroused Chen Aili's curiosity even more, and she stood between the two excitedly and said, "Ah, what a coincidence, this is really an unexpected surprise." Hey, Mr. Li, you didn't know that Dr. Su was coming in advance, haven't you been in touch? ”

Su Yaoguang interrupted Chen Aili's question with an embarrassed smile, and took over the conversation and said, "I was also temporarily sent to participate in the inspection, and I haven't had time to inform my old classmates yet." In fact, she didn't have Li Guanghan's contact information at all, and since she went to country M, the two have never been in contact with each other.

There was another moment of silence, and all three of them felt embarrassed. Fortunately, at this time, the leaders of Huajing University came over and greeted everyone with a smile to go back to the dormitory to clean up and tidy up, and hold a small welcome dinner in the cafeteria in the evening.

Chen Aili's room was next to Su Yaoguang, and she enthusiastically pulled Su Yaoguang back to the dormitory first. Li Guanghan was unprepared to see the dusty corner that he had not wanted to touch for more than a decade, as if someone had suddenly torn open an old scar, still dripping with blood. He felt as if his head was swollen, blood was pouring up, and his feet were unconscious, and he stood numbly in place.

47 Love-hate

The name Su Yaoguang used to be a strong color in Li Guanghan's youthful memory, and it was also the source of all happiness, pride, hesitation, confusion, and pain at that time. The name "Yaoguang" comes from the seventh star in the "Big Dipper", which means "the star that seeks innovation and change with light". In traditional Chinese Taoism, Yaoguang Palace is known as the Broken Army Star King, and at first glance it feels like a star with bad intentions. She once shined in Lee Kwang-han's life, and then flew away like a meteor. Their pair of twin stars, which once shone brightly on campus, dimmed for a long time after becoming a lone star. So much so that Li Guanghan didn't dare to look up at the starry sky for a long time, for fear of piercing the scar at the center.

Although it is deep in the mountains, there is no shortage of food where there are Sichuan people. The cafeteria wafts out from afar the unique Sichuan pepper flavor, bean paste flavor, and butter hot pot flavor. Chen Aili smelled it and only shouted that she was hungry. She knocked on Su Yaoguang's door and wanted to call her downstairs together, but found that she had been sitting in a daze, with no change of clothes and no luggage, and her mood was a little low.

Although the small welcome dinner party does not have delicacies from the mountains and seas, abalone and cucumber wings, it is definitely a feast of Sichuan home-cooked food. Everyone's interest was very high, especially the foreign experts who came to inspect the tour, who had already left the fatigue of the journey behind and had a warm exchange with the Chinese scientific researchers. Su Yaoguang is the only woman among foreign experts, and she is of Chinese descent, and she is also a senior sister who graduated from Huajing University, and soon became the object of conversation among young scientific researchers. Chen Aili saw that Su Yaoguang's state had adjusted, and chatted with everyone with a smile on her face. She secretly glanced at Li Guanghan and found that he had not changed his clothes, sitting silently by himself, not active at all, looking like he wanted to hide under the table. The smart Chen Aili has already guessed seven or eight points.

I don't know which troublesome junior brother suddenly remembered something, and asked Li Guanghan: "Teacher Li, it seems that you and Dr. Su should be at the same level as our department, right?"

Li Guanghan was asked unexpectedly, and the red oil tripe that he had just eaten in his mouth suddenly choked on his throat and coughed violently. He hurriedly took a sip of Babao tea and said in shock: "Yes, we have already said hello just now. He wanted to stop the little junior brother's mouth, but the little junior brother immediately coaxed: "Then we should arrange for the old classmates to sit together to make it easier to chat?" Frightened, Li Guanghan hurriedly grabbed him and told him not to toss. Chen Aili saw it really on the side, and almost laughed out loud.

The welcome dinner party finally ended, and Li Guanghan tried to keep a low profile at the dinner party and did not speak to Su Yaoguang alone. The two of them were unconscious in the spring sleep, and they both lost sleep at night when the wind and rain sounded at night. The past came to his heart one after another, and Li Guanghan's ruthlessness, deception, and betrayal of Su Yaoguang have not been let go of to this day, but they have also occupied a corner in his mind forever and lingered. Over the years, he has avoided participating in academic exchanges with her as much as possible, and has never cared about her academic achievements, in order to keep his mind as calm as water. Su Yaoguang, who is middle-aged, still has a trace of guilt for her selfishness, vanity, and competitiveness when she was young, and for a while she even wanted to renew her old friendship with Li Guanghan. But she quickly found an excuse for herself in her heart, she and Li Guanghan are still two people in different worlds after all, and she still puts herself first after all. She was terrified that she could not predict whether today's reunion would be a blessing or a curse for her, a danger or an opportunity.

Chen Aili couldn't sleep at the moment, with her woman's unique delicate mind and sensitive professional sense of smell, she thought that Su Yaoguang's arrival was extraordinary at this time.

It rained all night, and the sky finally cleared. Under the sunlight, the humidity in the valley slowly evaporates upward, and it suddenly makes people feel stuffy. As soon as the bus carrying scientific researchers and investigation experts drove into the tunnel, there was a chill on his face, and Su Yaoguang couldn't help but shiver. Yesterday's rain and insomnia at night made her well-maintained face look haggard, with puffy eyelids, dark eye circles, and deeper nasolabial folds. In fact, she felt a little unwell as soon as she arrived in Beijing, but because of the tight time, she didn't have time to seek medical treatment.

Li Guanghan was also full of fatigue, unable to keep his spirits up, and looked like he was in chaos. The minibus stopped at the entrance of the laboratory, and everyone got off one after another. The leaders began to introduce the mountain structure of the hydropower station and the geographical advantages of the laboratory to the visiting experts. Chen Aili walked up behind Li Guanghan and reminded him: "Teacher Li, how can you find dark matter like this, how can you find dark matter like this?" Li Guanghan was stunned for a moment, and then nodded.

Walking through the dark corridor, the lab leader explained that the design was designed to minimize the amount of light coming in from the tunnel mouth into the core of the lab. The experts came to Lee Kwang Han's dedicated laboratory, and Lee Kwang Han gave them a brief explanation. Su Yaoguang looked at his mature and handsome face, thinking about how to eliminate his hostility, resolve his resistance, and even let him rekindle the fire of love for himself. At this moment, she was like a hunter waiting for her time, and she forgot that she was still an expert in high-energy physics.
