The suitcase was still lying on the floor of the room and didn't have time to tidy up, so it saved the trouble of cleaning up again.

Early the next morning, Zhao Nanxiao arrived at the airport.

Chen Songnan was already waiting at the entrance with a big bag on his back and was looking around. When he saw her appear, his eyes lit up and ran over to help her get the box.

"I'll do it myself."

"It's okay, I'm empty!" Chen Songnan had already pulled the box into it.

On the plane, she asked the flight attendant for a blanket, put it on her body, and leaned against the seat to sleep.

Last night, she turned off the lights and lay down at less than 10 o'clock, but the biological clock had been completely destroyed - if people really had this thing, they would not be able to fall asleep at all. Later, they got up and went to the study to read the information about Qingling Bridge. They saw it all the time in the middle of the night before they got back to bed.

More than two hours later, the plane landed at the airport. The two of them traveled over 20 kilometers in the city to the train station of the city. They boarded the train to Y County where the bridge was located. They stopped all the way to the large and small stations. Finally, they arrived at the county town at around 2 pm and met the people from the local expressway management office that they were picking up.

The other party's surname is Yan, the secretary of the management office. When they first met, they thought Chen Songnan was an engineer sent by the design institute. When they learned that they had recognized the wrong person, they were a little embarrassed and apologized repeatedly: "I'm really sorry, Master Zhao, I blame me for being stupid, don't mind."

Zhao Nanxiao has become accustomed to this situation and said with a smile that it doesn’t matter.

Secretary Yan looked at the time.

"It's not too early. Or I'll take a night off in the county town today and I'll send you there tomorrow?"

Zhao Nanxiao asked how long it would take to go.

"The expressway is closed and you can walk the national highway for an hour and a half."

"Let's go straight away." Zhao Nanxiao said.

Seeing that she insisted, Secretary Yan agreed and enthusiastically led the way.

There were many construction vehicles running on the national highway, and the weather was dry and dusty. The cars were hiking around in the cracks of the construction vehicles. At around 4 o'clock in the afternoon, they turned onto the county road with less traffic and arrived in Qingling Village.

There were dozens of workers wearing safety helmets with the zj group logo on the scene, and forklifts and construction vehicles were constantly traveling back and forth, dealing with the mountains of falling rocks and soil under the bridge. When the workers saw that people were coming, they hurriedly called the manager.

The manager's name is Yang Pingfu, who was in his forties and rushed over. Like Secretary Yan, he thought Chen Songnan was the person in charge at first.

Chen Songnan hurriedly corrected and said that he was an assistant.

Yang Pingfu was stunned and stared at Zhao Nanxiao. The workers stopped working, surrounded her in groups of three or three, looked her up and down, and whispered to each other.

Zhao Nanxiao looks like a loose jacket, jeans and sneakers, and she looks really unstoppable.

"Is it a woman?"

"How old is she? Have you just graduated? Does she understand..."

The workers' discussion kept floating.

Secretary Yan coughed and lowered his face: "Okay, Zhao Gongda has been flying from Beijing from afar and has not even had a rest. He has arrived here directly. I can tell you that she is an expert sent by the Beijing Design Institute! What are you muttering about?"

The workers were blocked by the word "expert".

Secretary Yan seemed to be familiar with the manager and urged: "Old Yang, please introduce the details to Mr. Zhao!"

Yang Pingfu looked a little impatient.

This section of highway bridge is under the county road. On one side is the mountain suspended slope. The terrain is steep. When it was originally designed, in accordance with the principle of not destroying the natural mountain, the bridge span was adopted to adjust the span to reduce interference to the road being transferred. Some time ago, the local area encountered rare continuous rain. Nearly a month of bad weather caused the mountain to accidentally landslide. Several giant rocks weighing several tons rolled down from the top of the mountain at a slope of about 70 degrees, causing visual damage to the bridge.

The manager named Yang was probably really busy, or he didn't take her seriously at all, and he finished his introduction and said in an endorsement: "The collapse of the mountain has ended and has been reinforced. Geological experts have confirmed that there is no problem. The collapsed earth can be transported tonight. Please consult Mr. Zhao quickly and make a plan. We can hurry up and build a construction!" After that, he left her and left.

Secretary Yan hurriedly explained: "This section of the expressway was contracted by the road and bridge infrastructure under the zj Group. You should know better than me. Central enterprises and the world's top 500, and road and bridge infrastructure are not unqualified construction parties, but the work is just like this. There are a bunch of rough people, so don't be surprised by Mr. Zhao."

He changed his subject, "However, this place happens to be on the main road, and the highway is closed for one day, which is a loss for one day. The construction period requirements are really tight, so I'll bother you!"

Zhao Nanxiao knew about the situation introduced by Yang Pingfu before coming. He didn't say anything. He put on a hard helmet and called Chen Songnan and started on-site investigation. He was busy until dark. He initially determined that the roadbed on the side of the falling rocks, the No. 4-5 bridge pier, the box girder, the base of the inner corrugated beam guardrail and the outer anti-collision guardrail all caused huge impact damage.

There was a village primary school that had been relocated hundreds of meters away. The workers temporarily pulled electricity and lived in the school building at night.

The county town was far away, Zhao Nanxiao politely rejected Secretary Yan's invitation, and each of Chen Songnan packed an empty house, and spent the night in the noise of the construction truck carrying earthworks in three shifts.

It was indeed as Yang Pingfu said, they moved very quickly, and the next morning the earth around the bridge was cleared. Two technicians also came to the scene to assist. The workers of the construction team got idle and wandered around, watching Zhao Nanxiao and climbed up and down the bridge, holding notebooks to measure and record.

In the afternoon, she called several workers to cooperate with the Jingzai experiment.

After watching for most of the day, the workers no longer commented on her like she did when she arrived yesterday. When she heard that she wanted someone, she was happy to be sent by her and rushed to come up to help.

The jack was placed on the top of the test pile and the beam was installed. The driving workers followed the command and drove the car slowly to the test point. The pressure transfer system and the displacement deformation observation system were also installed. Zhao Nanxiao recorded the data while directing the pressure. Manager Yang suddenly came up and interrupted the experiment.

"I said to Mr. Zhao, can you hurry up? How long will it take for you to do this? We have done a lot of this kind of work, and you won't make mistakes even if you close your eyes! You don't have to worry about it. Sign up and we will start work, and you can go back early!"

Everyone next to him stopped and looked at Zhao Nanxiao.

Zhao Nanxiao continued to remember the data in his notebook, but his eyelids did not raise his eyelids: "You can build it immediately, and I can leave immediately, but I won't sign it. You can do it."

His face looked a little ugly and he stood without saying a word.

Zhao Nanxiao turned his head and said, "Continue!"

The workers came to their senses and said "Oh".

"The result will come tomorrow!" She thought for a while and said to Yang Pingfu again.

Yang Pingfu muttered and left in disappointment.

That night, in the dilapidated office that temporarily served as a residence, Zhao Nanxiao sat in front of a broken desk with a brick cushioned foot flattened with a brick, opened his notebook, and worked at his desk until late at night.

The next day, Secretary Yan, Yang Pingfu and others listened to Zhao Nanxiao's test results and the proposed repair plan in an empty classroom at the school. The two looked at each other and went out quietly. After a while, Secretary Yan came in, closed the door and smiled and said, "Mr. Zhao, discuss something with you. The repair measures for the bridge deck piers and guardrails you mentioned are fine, just box girders. Can the stretched carbon fiber board be changed into steel bundles?"

"Don't get me wrong, I'm not questioning," said Secretary Yan. "You are an expert from the design institute. Your opinion is definitely correct, but the plane involved is not small, so we have to consider the cost, right? I heard from the technician that similar issues are usually reinforced with steel beams, and there has never been any problem. The construction of the lower part is easy and more convenient."

Zhao Nanxiao said: "The box girder is a prestressed A-class component. The original design standard for the expressway was to meet the passenger car with an average daily traffic volume of 15,000 to 30,000 yuan. Moreover, this section of the bridge is at the hub position, and the damaged part is in the key parts of the bearing capacity. Considering it from multiple parties, combined with the damaged detection grade results, I think carbon fiber board should be reinforced, which is more durable than steel bundles."

Secretary Yan showed a hint of embarrassment: "This... not only will the economic cost increase, but the construction period also need to be extended, and we have suffered a lot of losses..."

"I understand, but I'm sorry, for me, safety standards are the first, and there is no room for change unless the owner terminates the entrusted relationship with our company."

"Okay, okay, I understand. I'll go back and report to the leader to get the approval. Mr. Zhao, please be busy first."

Secretary Yan blew and hurriedly left with the documents.

It was dark, and Zhao Nanxiao returned to his residence from the bridge construction site, closed the door, opened his notebook to work, and suddenly heard someone knocking on the door.

She went over and opened the door.

"Manager Yang? Is there anything wrong?"

Yang Pingfu changed his impatient attitude when he was looking at her two days ago, smiled and pointed: "Mr. Zhao, can I come in and speak?"

Zhao Nanxiao opened the door. Yang Pingfu flashed in and said with a smile: "Mr. Zhao, just call me Lao Yang. I was not good at you two days ago. It was my fault. I regret it very much. Now I come here to apologize to you. I am a rude man and have never read two books. Don't bother with me." After that, I bowed to her.

Zhao Nanxiao stopped him: "It's okay, everyone has their own duties, everyone has difficulties, I can understand."

"You are really a wise man, and you are a very important intellectual from Beijing!"

Yang Pingfu flattered her for a few more words, looked at the place where she lived, and shook her head: "Mr. Zhao, you came to guide us from all over the place, and you also wanted you to live in such a broken place. Thank you so much, I have nothing to say. I have little intentions and no respect, don't dislike me." As he said that, he took out an envelope.

"...Mr. Zhao, don't worry, I'll forget everything when I'm out. Please rest, I'll leave first, I won't bother you." He put down his things and turned to leave.

The headquarters of zj Group is in Beijing and has some connection with Zhao Nanxiao's grandfather. Her grandfather not only served as the group chief engineer, but also worked as a grandfather's student before joining the railway squad when he was young. Now his grandfather is old and although he has stepped down, he is still a technical consultant of the group.

zj is also an old partner of the design institute. Over the years, both parties have completed many large-scale national infrastructure projects together. Zhao Nanxiao is naturally familiar with this company. The road and bridge company has more than 100,000 employees nationwide. For example, such temporary sudden local projects, subcontracted to the bottom, will inevitably involve certain interests of the owner's construction party or material supplier.

Zhao Nanxiao is not a rookie who just left school. As soon as Yang Pingfu arrived, she guessed what the other party wanted to do.

"Wait!"

She called the person and picked up the envelope and handed it back. "Old Yang, take it back."

Yang Pingfu looked prepared and took it into his arms again, as if he wanted to add it.

Zhao Nanxiao said: "I still say the same thing. For me, the plan cannot be changed."

Manager Yang's hand stopped in his pocket, looked at her for a while, took the envelope back, and turned around.

Zhao Nanxiao closed the door and sat back.

The night is getting deeper.

The surroundings became quiet, and the noise of playing cards from the workers living opposite disappeared, and the sound of whimpering wind from the distant wilderness was faintly heard.

Zhao Nanxiao rubbed his temples on both sides of his swelling and pain, stood up and was about to boil water and wash and rest when he suddenly heard a slight abnormal sound from the direction of the window. He turned his head and saw a twisting snake on the ground in front of the window.

This is not the first time she has gone to the construction site, nor is she encountered a wild snake. She recognized it at a glance. Although the snake has black skin and green patterns and looks terrifying, it is commonly known as cauliflower, a very common snake in the wild. Even if it is bitten, it is only bleeding and painful in the wound, and it is not poisonous.

She looked at the window.

The school building was dilapidated and the windows were incomplete. When she lived there that day, Xiao Chen helped her nail it with wooden boards, and then covered the entire window with the opaque plastic film on the construction site, as a curtain.

She remembered clearly that the plastic film was wrapped tightly, without any leakage. But now, the inconspicuous corner on the left was broken and there was a small hole.

She calmly picked up a steel bar that was facing the door when she was sleeping, saw it right, pressed the snake on the ground, then walked behind the door and opened it.

A worker was listening to the movement inside when he saw the door open suddenly. She stood behind the door, frightened and turned around and ran away.

"Stop!" Zhao Nanxiao shouted.

The worker stopped, nodded and walked back.

"Mr. Zhao, haven't rested so late? I've just passed by... Oh, there's a snake in your room? I'll catch you!"

The workers are going to come in and catch snakes.

Zhao Nanxiao glanced outside the door, picked up his cell phone, and dialed a number slowly.
