The mountains are covered with trees and yellow mud, and the outside looks dry and solid, but deep in the mountain, there may be a surging water source. As the tunnel opens and breaks in, once it encounters or approaches the groundwater source that cannot be detected before, the damaged broken rock mass is very likely to be unable to support it.

As the internal construction of this tunnel deepened, weathered layers of faults appeared one after another. A few days ago, after the fault area was suddenly flooded with water and mud. After stabilizing it, today, nearly two thousand cubic meters of mud suddenly appeared, and then a large area of ​​slate above the head collapsed. Anyone with a little experience in the tunnel knew that the structure of the nearby mountain had changed. The danger can be imagined and work must be stopped and rectified.

The shutdown lasted for more than a month. In order to ensure the safety of surveyors, the project department sent a large pipeline with a diameter of 200 meters and one meter into the landslide area to ensure that in extreme cases a safe passage for staff to escape quickly. Then, the project department not only held countless meetings within, but also invited tunnel geological experts from all over the country to conduct investigations and demonstrations. After more than a month, it finally developed a reinforcement plan with the most recognized opinions. However, no one including experts dared to make a decision to ensure that this plan with safety guaranteed theoretical verification will not have any accidents in actual construction.

If anything happens, it is human life.

The bridge and tunnel that had been erected had to be dug in. The experts left after giving suggestions, and the construction was still shelved. However, after a day of delay, various related losses were often hundreds of thousands. Mr. Ding, Mr. Liang, and the relevant person in charge of the bridge and tunnel project were not anxious. Mr. Ding was originally anxious, and the corners of his mouth were blisters. He sent the experts away and called people for a meeting overnight when he came back.

Mr. Liang said: "Don't be anxious, it's useless. The laboratory has collected all the on-site data. Xiao Xu and his men were modeling and analyzing the reliability of the plan with the assistance of geological technicians. Please be patient and wait until the results come out before further discussion. The problem can always be solved."

Although the design institute did not participate in this related project, there was such a big problem and it took more than a month to delay it. Lao Chen and Zhao Nanxiao were also very concerned. For the purpose of understanding the situation, they also came to attend the meeting in the evening.

Naturally, the meeting ended in vain. After the meeting, Zhao Nanxiao went to the laboratory at around 10 o'clock. Before entering, he stopped outside the computer room. Through the window, he saw Xu Shu and more than a dozen colleagues discussing the problem.

He has not had time to go to get a haircut recently, and his work and rest are irregular. From morning to night, he either stays at the tunnel construction site or soaks in the laboratory. His hair is messy, his brows are slightly frowning, his expression is focused, and he interrupts and explains questions from time to time, and modifys data in his notebook.

Zhao Nanxiao looked at him outside for more than ten minutes, but he didn't notice it. She was about to go back quietly. Old Li and a chef came over with a midnight snack and shouted from behind: "Mr. Zhao, why don't you go in?"

When Xu Shu heard this, he turned his head and saw her, and immediately came out: "Why are you here? Is there anything wrong?"

"It's okay, I'll come and take a look at it at night." Zhao Nanxiao looked at him with a smile, "How is the progress?"

"It's going well. I have to do it early, I probably have to work overtime tonight..."

He has been back to rest for more than a week and only one or two o'clock in the middle of the night.

Zhao Nanxiao really wanted him to go back to bed early, but he knew that when he encountered such a situation, he would be tormented to him.

She could fully understand his mood and desire to work.

Fortunately, such accidents will not happen often.

"Okay, you'll be busy after having a midnight snack. Try to come back early to rest. I won't bother you, I'll go back first."

She raised her hand, pressed a cluster of stubbornly raised hair for him, said with a smile, and turned around and wanted to leave.

"Wait. Everyone needs a rest too. I'll take you back first. You can have something to eat with me."

He went in, took out a bag, and took her back to his residence. The two of them ate the midnight snack one by one, and finally hugged her and kissed her, asking her to go to bed early, and then he left.

He didn't return that night, probably fell asleep in the laboratory later. Two days later, Zhao Nanxiao was a little absent-minded at the site of Dongsuota and the engineers at the supervision station at the supervision station.

She was worried about Xu Shu’s situation.

Yesterday, after more than half a month of overtime and repeated verification in the laboratory, the simulation results of the computer finally came out, and it was also determined that the reinforcement plan was feasible. After the meeting, the leader finally made a decision and decided to implement it. Today is the day to re-enter the hole and reinforce it.

She knew that Xu Shu had gone to the tunnel site early in the morning. She didn't know what the situation was now, so she called Xiao Hu, a technician in the laboratory. She was told that when she was summoning relevant workers to explain the situation in the morning, there was a little accident. General Manager Ding and General Manager Liang and others were on the scene now.

Zhao Nanxiao was unintentional to do things, so he immediately came out and went down the canyon to the opposite side.

Some time ago, in order to further improve safety production standards and intelligent management, the project department not only equipped all personnel involved in dangerous construction with intelligent safety helmets with advanced functions such as real-time tracking of location and identity authentication, but also upgraded the gate system on all sites on the construction site. Only by passing facial recognition and alcohol testing at the same time can you enter.

Zhao Nanxiao's identity authentication has not been authorized here and cannot be entered. He was outside and saw many people surrounding a tunnel construction entrance several hundred meters away from a distance. There were workers, team technicians and leaders. Because of the distance, they could not hear what they were saying, so they hurriedly called Xiao Hu again.

Xiao Hu ran out and explained the situation to the management staff, and then she finally went in.

"What happened again?" Zhao Nanxiao asked while going in.

Xiao Hu told her that the workers were afraid and still dared not go down the hole to construct. They were trying to explain to dispel the concerns of the construction workers.

Zhao Nanxiao hurried over and saw Lao Li, the construction manager of the tunnel section, shouting to a group of people: "...Don't worry! This plan is a scientific method that is improved on the basis of the new Austral Method. After many verifications, we not only invited the best relevant experts in the country, but our laboratory with the world's most advanced equipment also completely simulated the entire reinforcement process. The result proves that the support is sufficient. As long as you strictly obey the command, scientific construction, and secondary evacuation of dangerous stones, there will never be a collapse again!"

From the technical leader to the safety team to the team workers, none of them spoke out.

The person in charge showed helplessness and turned to Xu Shu and said, "XCMG, you are the head of the laboratory, or do you tell everyone about your work results?"

"Mr. Xu, no matter how well you speak, we can't understand it!"

A worker below shouted, "The six or seven hundred meters of mountain hinterland is not a joke. Who knows whether the plans developed by those experts are reliable? They have collapsed once, and they are not afraid of ten thousand, but they are afraid of what if. We are here to make money, but no matter how much money we give, we cannot work hard, right?"

The others also agreed, the workers took off their hats and the scene was in chaos.

Xu Shu and the workers calmed down and said, "I will take you into the cave and into the landslide area in one sentence. You and me will not come out until you finish it."

"I want to smash it, I'll be the first to smash it!"

His tone was plain, as if he was talking about something very ordinary, but as he finished speaking, the person who was still noisy just now became quiet.

The scene of hundreds of people became silent, and everyone looked at him. Soon, the lower part became commotion again. Everyone whispered and talked in a low voice, with an expression of disbelief on their faces.

"Don't believe it?"

Xu Shu smiled, put on his hat, and turned to the person in charge.

"Old Li, please prepare all the members of your team and come in with me!"

The person in charge looked embarrassed and hurriedly went up to dissuade him. Xu Shu had already walked towards the entrance of the cave.

The person in charge quickly ran to Mr. Ding and Mr. Liang who were watching this scene, and whispered: "Mr. Ding, Mr. Liang, XCMG should not go in, if..."

Mr. Liang looked at Xu Shu's back, whispered to Mr. Ding, walked over, and said loudly: "I am the chief engineer, and I recognize the results of the laboratories and teamwork. Don't be afraid, I will join you in!"

"Let's go! Mr. Xiao Xu and Mr. Liang both come in. What are we afraid of? We have been pausing for more than a month and we have to have dinner!"

Everyone's expressions relaxed, and someone shouted again, and there was a sound around him.

Xu Shu's simple statement is enough to surpass all the construction workers on site to encourage and give a high-level scientific explanation.

Zhao Nanxiao stood behind the crowd, and the tension and excitement in his heart at this moment was beyond words.

She believed that he would make such a decision and would be full of confidence in the team's experimental process and results.

But even so, it undoubtedly requires great responsibility and courage.

Besides, this book is not within his responsibilities.

Only men like mountains can make people completely trust and trust.

Somehow, at this time, Zhao Nanxiao suddenly remembered a sentence he saw in his father's work diary.

She looked at the back in front of her that was heading towards the entrance of the cave without blinking. She almost rushed over to call him, but she was worried about so many people around her. She was feeling uncomfortable when she suddenly saw him stop and turned to look over, and her eyes soon found her in the crowd.

The two looked at each other.

He seemed to be stunned at first, then he smiled at her and brushed his hand. She knew that he was telling him to leave with confidence. Then he turned around and walked in.

More than 100 people were arranged to eliminate the insurance, and the three shifts were continuously working until the next night.

Coincidentally, the next day happened to be Labor Day. Celebration banners were drawn at the gate of the construction site. Except for here, all the construction sites were on holiday for one day, dinners were gathered at night, and literary and artistic activities organized by the branch. During the day, everyone flocked to the county town.

The entire project site is immersed in the relaxing atmosphere of the festival, and only the tunnel construction site here is still under intense construction day and night.

As expected, it should be completed before 10 o'clock in the evening.

Secretary Yao, who had been here to guide the poverty alleviation work in relocation last year, went to the group branch to participate in the May Day celebration in the past two days. After hearing the news, he immediately adjusted his itinerary and rushed here to the distance in the afternoon. He said a few words at the cultural and artistic activities in the evening. He went out of the tunnel with Mr. Ding and other leaders of the project department, waiting for the construction to be completed.

Zhao Nanxiao also came. It was earlier than expected. At around nine o'clock, Mr. Ding said a few words on the walkie-talkie in his hand, turned around and said excitedly: "The rescue victory is over, and they will come out soon!"

Zhao Nanxiao let out a long sigh.

Soon, she saw Xu Shu, General Liang and team members walking out of the tunnel together. There was applause from the scene. Secretary Yao quickly stepped up and shook hands with General Liang, congratulated the success of the rescue. After the condolences, he turned to Xu Shu, looked him up and down, then raised his hand and patted his arm: "Not bad, Xiao Xu, what rewards do you want, just say!"

As soon as he came out of it, Zhao Nanxiao felt that he saw himself in the crowd and kept looking.

After Secretary Yao praised him, he didn't respond and looked at her again.

"Is this a matter of saying? Secretary Yao, hello, I'm sending Xiao Xu a wife! I see that he's looking at Xiao Zhao as soon as he comes out."

An engineer who came out of the tunnel who usually likes to joke said casually.

Secretary Yao was stunned and followed Xu Shu's gaze and suddenly realized when he saw Zhao Nanxiao, he laughed: "This is too great, I can't make a decision. I have to ask Xiao Zhao if he is willing."

Everyone looked at Zhao Nanxiao, and there was a kind and pleasant laughter on the spot.

Zhao Nanxiao didn't expect that he suddenly became the focus of attention. He was a little embarrassed and looked at Xu Shu quietly. Seeing that he was still looking at him, he couldn't escape anyway, so he smiled at him openly: "I'll go back first, you're done, and go to rest early."

She greeted Xu Shu who had never spoken after she came out, and smiled and nodded to Secretary Yao, the other leaders and the people around her, and quickly turned around and slipped away.

Xu Shu didn't delay for long and came back before ten o'clock. He didn't even have time to take a shower. He immediately knocked on her door and leaned against the door and whispered, "Sorry, I probably worried you. I'm very sure of the results in our laboratory, so I dared to do this, otherwise they wouldn't believe it."

After he said that, he looked at her with a little nervousness in his eyes.

Zhao Nanxiao smiled and said softly: "I'm a little worried, but I really believe in you. It's okay, go take a shower quickly. Come back and take a break early. You must be tired."

He seemed to breathe a sigh of relief, looked at her gratefully, nodded, and then turned around and walked away.

He must have been really tired. He worked overtime for half a month in a row. In the past two days, he worked with Mr. Liang almost three shifts with the rescue team. After returning from taking a shower, he did not knock on her door again and sent her a good night message. Then, the next door became quiet.

Zhao Nanxiao knew that he should go to bed.

The night is getting deeper.

The music in the direction of the art performance venue was stopped. Today, the construction site was suspended from night shifts. I heard the various faint noises from mechanical work that I had used to in my ears.

The hustle and bustle of a daytime canyon became extremely quiet.

Zhao Nanxiao really couldn't sleep.

Her worries have never been eliminated, and it is even more deadly. When she went there, the house where Ren Gong lived was transferred last month, another engineer moved in. His wife came here to see him two days ago. After a long separation, she would inevitably lose control.

Tonight, at this moment, late at night, even though it was already separated by a room, Zhao Nanxiao, who was awake, still heard some suspicious slight sounds that were suspected to be inappropriate for children.

At first she plugged her ears into her ears and listened to the song. After listening for a while, she felt that the room was quite boring, so she got out of bed and opened the window. She went to the window to open the curtains, and she paused.
