In the morning, before Xu Qiang and Han Xuefei went to work, they received an urgent call from the resort construction site, and something serious happened on the construction site.

The two of them didn't care about going to work, so they immediately hurried to the construction site.

When the two arrived at the construction site, they found that the workers had gathered and gathered around the construction site, all kinds of large machinery.

"What's going on?" Han Xuefei's face was very ugly.

Now she is in charge of the project, if everything goes well and makes money, no one may praise her, but if there is an accident, the Han family, who has long been dissatisfied with her, will definitely stand up and make trouble.

She's been worried, too, and now it's finally happening.

"Chairman, Mr. Xu, there is a problem with our machine, three machines broke down when they started, and I suspect that other machines may also have problems, so the other machines are not allowed to start. Responsible on the construction site, project manager Song Qingshan immediately trotted over.

"Are you sure what the reason is?" Han Xuefei's brows furrowed even tighter.

If there is a problem with one or two units, it is normal, it is normal loss, but if there is a problem together, it may be abnormal.

"Not yet, professional maintenance personnel are needed to inspect it, the maintenance personnel haven't arrived yet, it's probably soon!" Song Qingshan said helplessly.

"Hurry them up!"

"Isn't there anything on the site that will be repaired?" asked Song Qingshan.

"Yes, but it can only be maintained in the simplest way, he has seen it just now, and there is nothing he can do!" Song Qingshan was also very anxious.

Because he was ordered by Han Xuefei to be in charge of the project of the resort, if he did a good job, he could be promoted with a salary increase, and if he didn't do a good job, he might be demoted and reduced.

Of course, he wanted to solve the problem as soon as possible, but the problem was that he didn't understand the mechanical aspect, and he had to wait for a professional to come to determine the cause and solve the problem.

It's useless for him to be in a hurry, so he can only wait like everyone else.

"I'll take a look!" Xu Qiang said with a sigh.

"You, are you okay?" Hearing that Xu Qiang wanted to try, Han Xuefei showed a suspicious look.

"Man, how can you say no?" Xu Qiang smiled mysteriously.

Ask him if he's okay?

Of course he did!

When he was on a mission in the past, he used to disguise himself as a maintenance worker on the construction site, and the basic maintenance of various machinery was not a problem, and his technical level far exceeded that of ordinary maintenance workers.

If he is unemployed, he will definitely hire him with a high salary as long as the person in charge understands technology.

"Chairman, Mr. Xu, he ......" Seeing Xu Qiang go straight to an excavator, Song Qingshan was also a little stunned.

"It's okay, let him go!" Han Xuefei said to Song Qingshan.

At this time, Xu Qiang had already boarded the excavator and easily opened the engine cover.

In less than two or three minutes, the problem was already found.

It's bursting!

The problem was serious, and the entire engine needed a major overhaul.

He then went straight to another hook machine and found the same problem.

The third machine was also checked, and the problem was the same as the first two.

It's just that there are many factors for the cylinder burst, and he must find out the reason, thinking of this, he took a closer look and suddenly found that the lubricating oil was wrong.

There are some particles in the lube that look like sand.

The basic function of lubricating oil is lubrication, and it is absolutely not allowed to have sand in it, otherwise it will not only fail to lubricate, but also damage mechanical parts.

"Is it the sand that sticks to the cylinder after the cylinder bursts, or is there sand in the lubricating oil in the first place?" With this question, Xu Qiang continued to disassemble the engine.

It was quickly taken apart and the lubricating oil inside the engine was checked.

"There is sand in the lubricating oil!" After dismantling it, Xu Qiang found that there was also sand in the lubricating oil inside the engine, and the three machines were the same.

If you find sand in the lubricating oil, you can be sure that it is not an accident.

The three machines were damaged because of the addition of lubricating oil with sand, which could not have been in the lubricating oil and was clearly artificial.

"You guys, go check all the other machines and see if there's any sand in the lubricating oil!" After identifying the problem, Xu Qiang asked everyone else to move.

Because there are a lot of machinery on the construction site, it is a waste of time to let Xu Qiang check them one by one, so it is better to let everyone move.

After a quarter of an hour, all the results came back.

Most machines have sand in their lubricating oil, and only a few are spared.

Song Qingshan wiped the cold sweat on his head, fortunately, he found the problem in time just now and forbade other construction machinery to start, otherwise there would be more than three broken ones.

"Now that the problem has been determined, someone adds sand to the lubricating oil of construction machinery, once the machinery is started, the sand will destroy the parts, when was the last time you added lubricating oil to the machine?" asked Song Qingshan.

"It was the afternoon before yesterday!" Song Qingshan replied.

"No, there is sand in the lubricating oil, there will be problems as soon as the machine starts, the machine was damaged this morning, the lubricating oil with sand was added after you stopped work yesterday and before the start of work this morning, call the people on duty on the construction site at night!"

Under Xu Qiang's order, 8 people were soon called over, 8 of them were on duty last night, and after starting work this morning, they had already gone back to rest after work.

They came with some tiredness on their faces.

"Did you notice anything unusual last night?" Xu Qiang asked Han Xuefei to rest beside him, and just leave these small things to him to deal with.

Then he came to the front of 8 people, and his nose couldn't help but twitch.

The lubricant in question must have been added last night, and these 8 people who were on duty last night, if they had done their due diligence, would have found some problems.

"No!" the eight men looked at each other and shook their heads.

"Think about it again, what did you do last night?" Xu Qiang's face turned gloomy, he had already found the problem.

"We were on duty on the construction site last night, and our eyes were wide open all night, and there was nothing abnormal!" said eight people who were very responsible.

"You drank last night?" Xu Qiang smiled coldly.

The smell of alcohol exudes from the 8 people, and they can't hide it from their noses at all.

"No, there are still rules on the construction site, don't drink at work, don't go to work if you drink, we abide by the rules!" The faces of the eight people changed and they shook their heads at the same time.

"It's useless for you to deny it, if you drank last night, it will be more than ten hours at most, and there must still be alcohol in your body, and you will understand everything as soon as you go to the hospital for a test, aren't you telling the truth now?" Xu Qiang snorted coldly.

Although 8 people have sobered up, it does not mean that the alcohol in their bodies has been completely metabolized, just like a drunk driver, not necessarily drinking today, maybe it was the wine drunk yesterday, but after a night, the alcohol has not been completely metabolized, and everything has been detected in a blood test.

Hearing Xu Qiang's words, the faces of the eight people suddenly changed.

"You guys actually drank while you were on duty?" Seeing the performance of the eight people, Song Qingshan's face changed.

Can they still do their duty if they drink while on duty?

Of course not, if you get drunk at night, even if a stranger breaks in on the construction site, a group of drunks can't find out.

"Manager, we only drank a little bit of ......" Seeing that they couldn't hide it, the 8 people had to bow their heads and admit it.

"Then do you know that because of your dereliction of duty, three construction machinery were damaged, and they can't be constructed normally today, do you know how much loss it will bring to the group?" Song Qingshan was furious.

Check the surveillance!

I can't ask anything from the mouths of 8 people, I just hope that the surveillance can take some useful pictures and provide some valuable clues.

turned on the monitoring, Xu Qiang's face became gloomy.

"What's going on with surveillance?" Song Qingshan was about to cry.

Because when Xu Qiang wanted to check the monitoring, he found that the monitoring was turned off, and the monitoring system has been suspended from last night to now.

"Manager, I accidentally broke the ......," said one of the eight people.

The eight people on duty drank and neglected their duties, and the surveillance was turned off.

"Very good, you 8 people are very good!" Xu Qiang didn't know what to say.

"Mr. Xu, you can check the monitoring on the surrounding construction sites, our construction sites are next to each other, maybe their monitoring will take some clues!" Song Qingshan suggested.

Xu Qiang nodded!

In the center of the overall project of the resort, if you want to enter the construction area of the Han's Group, you must pass through the construction area of other units.

The people who came in last night may have been filmed by the surveillance of other units.

Xu Qiang nodded and asked Song Qingshan to communicate.

It didn't take long for the other units to agree to look at the surveillance.

"You go back to the group first, and I'll handle this matter!" It takes a long time to check the monitoring, and the group still has a lot to deal with, Xu Qiang asked Han Xuefei to go back to work first.

"Thank you for your hard work!" Han Xuefei nodded.

She is responsible for the operation of the entire group, and the resort project is only a small part of the project, and she cannot stay on the site forever.

Han Xuefei left, and Xu Qiang took the workers to check the surveillance video.

At this time, there was no damage to the construction machinery, and there were already professionals who cleaned the lubricating oil with sand, and finally started everything normally.

The construction site resumes normal construction!

"Wait, play back for half a minute...... "When viewing the surveillance footage, the usual speed is the fastest, four times the speed.

And others at a maximum of twice as fast, otherwise they will be dizzy and unable to see clearly.

In the afternoon, Xu Qiang finally found a suspicious place, and then checked it upside down and found that at about 2 o'clock in the evening, a person appeared on the construction site.

It was a man who walked a little shaky.

It's just that the man looks defensive, wearing a baseball cap on his head and a large mask, and he can't see his face at all on the surveillance.

"Quadruple speed, fast forward......" Xu Qiang frowned.

If you can't see the man's face, it's hard to determine your identity.

The man was carrying a jar in his hand, and when he entered the construction area of the Han Group, he disappeared into the monitoring area, after all, it was the monitoring system of other units, and it was not allowed to monitor the construction area of the Han Group.

Half an hour after the interval on the surveillance video, the man reappeared and returned the same way, still carrying a jar in his hand, but judging from the walking posture, the weight of the jar was significantly lighter.

Boom!

As the man was staggering along, he suddenly fell to the ground, the jar in his hand flew out, the hat on his head fell off, and the mask fell off.

"Quick, zoom in, zoom in, make his appearance clearer......" Xu Qiang was overjoyed, now he can see the man's face clearly, and he blames the man's luck for being so bad that he actually fell.
