At this moment, it was the dead of night, and the whole building was silent, although because it was an important place for scientific research, and security forces were arranged inside, but it was still silent in its core part.

Cheng Xuedong browsed all the way, trying to slow down his steps, so as not to make a harsh movement that would disturb the security guards cruising around.

In fact, he is not very familiar with the interior of the whole building, and the place he usually goes to most often is Nan Binghuai's office. As a result, he felt his way to the door of the office.

Suddenly, with the help of the light in the corridor, he found that the door of Nan Binghuai's office seemed to be hidden, and there was still a light inside. It made his heart flutter - there were people inside. Teacher Mo Feinan is still inside?

Tuk Tuk!

He tentatively tapped twice on the door, but there seemed to be no response inside.

Squeak!

He slowly pushed the door open.

When he stepped inside, he stopped in amazement - Nan Binghuai was leaning back in his seat and let out a slight snoring sound.

Could it be that Mr. Nan sleeps in his office like this every day?

Cheng Xuedong felt incredible, and slowly approached Nan Binghuai with light steps, but after not seeing him for a few days, the other party had already had a scruffy beard, and obviously he hadn't repaired it for several days.

Cheng Xuedong's heart was sour, he hadn't seen him for a few days, not only his hair was white, but the gray hair on Mr. Nan's head had also increased, and the whole person looked so haggard.

He stared at Nan Binghuai silently, he really couldn't bear to disturb the tutor's dreamland, and felt that the temperature in the room was not enough, so he took off his coat and gently covered the other party's body.

He stared at Nan Binghuai silently for a while, and finally realized that it was the responsibility on his shoulders that made him not even care about his wife's birthday. Indeed, as the chief scientist of this national super project, the pressure of the construction of the entire project and the final success or failure fell on him, and this sense of oppression and mission can be imagined.

"Teacher Nan, you can sleep steadily, even if the road ahead is thorny, we will accompany you, even if the challenges in the future are great, we will bear them with you."

Cheng Xuedong muttered a few words silently in his heart, then gently exited the office, and then gently closed the door.

Perhaps there is the power of Nan Binghuai's example, which makes Cheng Xuedong's footsteps on the way back to the dormitory extremely solid. He is convinced that with the encouragement of Nan Binghuai's spirit, their scientific and technological team that created Tianyan for the country will definitely overcome many difficulties and achieve the final victory.

When he returned to his dormitory, he quickly fell asleep.

By the time he opened his eyes again, the sunlight was already shining on the bed.

He rubbed his sleepy eyes, but they didn't open them immediately, as if he was reminiscing about his previous dream.

Suddenly, he felt the quilt covering him a little heavier, as if something had been attached to the quilt, and he didn't need to widen his eyes—

Huh, what's going on?

When he looked at it, he sat up. It turned out that the coat that was draped on Nan Binghuai last night had come back and was covering the quilt.

He couldn't help but look around, and the door was closed as if nothing had happened. But he knew that Nan Binghuai must have come. When he looked at the time displayed on the screen of his phone, it was already seven o'clock in the morning.

He quickly got up and cleaned himself up, and then hurriedly left the dormitory.

When he went straight to Nan Binghuai's office, he found that it was already empty.

He thought for a moment, and immediately walked deeper into the hallway—

In that spacious studio, Nan Binghuai is now the only one alone. Because it was still early, his assistant and the rest of the team had not yet come to work. He was sitting in front of a desktop computer with a large screen, using his mouse to dot the structural diagram displayed on the screen.

Cheng Xuedong walked in at this time, and when he saw that Nan Binghuai didn't notice it, he didn't bother him directly, but quietly poured him a glass of warm water and put it in the corner of the table.

Nan Binghuai finally noticed it and immediately turned around: "Did Xiao Cheng sleep well?" ”

Cheng Xuedong nodded first, and then questioned: "Teacher Nan, do you sleep in the office every day?" ”

Nan Binghuai explained with a smile: "I work late every day, no matter where I sleep, it is inconvenient, so I make do in the office in order to save time." ”

"What's going on?" Cheng Xuedong said angrily, "It doesn't matter if it's three or five nights, but if it's a long time, your body won't be able to bear it." ”

Nan Binghuai refreshed his muscles and bones: "It's okay, I feel that my body is okay, especially taking over this work, I am so excited that I feel like I have returned to my youth." ”

Cheng Xuedong couldn't help but shake his head: "But after all, you are past the year of the sixtieth year, so you can't fight like this." ”

Nan Binghuai's face changed slightly, and he immediately changed the topic: "Have you settled down at home?" ”

"Well, it's all arranged."

"How's Sook-jin doing?"

"She's okay and very supportive of my work."

"I never doubted Shuzhen's attitude, but I was worried that she wouldn't be well taken care of."

Cheng Xuedong hurriedly said: "Liu Yan is currently taking care of her. ”

Nan Binghuai was stunned: "Who is Liu Yan?" ”

"She is a young generation of scientific and technological workers at the Shangjiang Observatory, and she is also a student brought out by Shuzhen herself."

Nan Binghuai looked surprised: "She must be a promising science and technology star, right?" How can you do the same job as a nanny? ”

"That's right." Cheng Xuedong further explained, "Because Shuzhen retired from the observatory early, Liu Yan was very unhappy at work, so she asked the organization for a long leave and moved to my house. However, Shuzhen's health is improving, and when Liu Yan is bored at my house, she will take the initiative to go back to work. ”

Nan Binghuai was very unimpressed by Cheng Xuedong's explanation: "Alas, those who do our work must have a rigorous work attitude. A girl like her lacks patience and may end up with nothing. ”

Cheng Xuedong couldn't help but hang his head: "I think, she is still too young, she is not yet thirty years old this year." It is good for her to stay with Shuzhen for a while, so that she can take care of Shuzhen and get enlightenment from Shuzhen. Actually, she is quite perceptive. ”

"Oh, I hope so."

Cheng Xuedong diverted the topic at this time: "Teacher Nan, can I join the work now?" ”

Nan Binghuai glanced at him: "Have you rested well?" ”

Cheng Xuedong nodded: "I've rested." ”

"Oh, then you get acquainted with the work here for a few days, and then go out and do the site selection work."

Cheng Xuedong was a little puzzled: "It's still winter, and many places are freezing, is the location so urgent?" Moreover, we still have a long way to go before construction begins. ”

"Xiao Cheng, you may not understand this. Since our instrument is placed outdoors, the surrounding meteorological environment is very demanding. In this season, you can fully grasp the meteorological data of various regions of the country. ”

Cheng Xuedong explained through Nan Binghuai, immediately understood, and immediately said: "Okay, I'm going to go to the south with me." ”

"Oh, why go south?"

"I don't think our Sky Eye is suitable for an area covered with snow and ice. In any way, it is suitable for resettlement in the south, preferably in the southwest, where rain is scarce. ”

Nan Binghuai's eyes lit up: "Okay, you're actually already studying this issue." ”

Cheng Xuedongguan smiled: "I'm just thinking about it." ”

"Well, now that you already know this, you can reduce a little detour. Since the most suitable place for this eye to be placed in the whole country, you need to provide a lot of candidate areas, establish a local meteorological observatory, and prepare for the final site. ”

Cheng Xuedong nodded solemnly: "I understand, I must strive for excellence in the details of site selection." ”

Nan Binghuai smiled with satisfaction: "Well, it makes me feel very relieved that you can think so." ”

While talking, the team members who participated in the drawing came to work one after another, and when they saw Cheng Xuedong there, they all greeted him one after another. After all, Cheng Xuedong's fame is not small, and he is an accomplished scientist brought out by Nan Binghuai himself.

Because Cheng Xuedong did not participate in the preliminary work of drawing drawings, it was inconvenient for him to express his opinions, but he just observed them one by one like a student.

At this moment, Nan Binghuai suddenly patted him on the shoulder.

Cheng Xuedong was stunned: "Teacher Nan, what's the matter?" ”

"Xiao Liu sent you here yesterday, right?"

Cheng Xuedong nodded: "Yes." ”

"Did he tell you to take a leave of absence today?"

Cheng Xuedong shook his head blankly: "No!" ”

Nan Binghuai's face was gloomy again: "What happened?" He's been always late for work lately, isn't he enthusiastic about this work? ”

Cheng Xuedong was startled, and quickly shook his head like a rattle: "Impossible." Xiaoguang has always been proud to participate in this project. ”

"But there's something wrong with his work attitude."

Cheng Xuedong pondered: "Maybe he has personal difficulties, right?" ”

"Okay, you can contact him now, what's wrong with his family."

"Okay, that's on me."

As soon as Cheng Xuedong and Nan Binghuai left, they immediately dialed Liu Xiaoguang's phone-
