Four dead at once?

If it wasn't for that Kai Ge who killed him, it must have been something that happened in the building!

Combined with the wet soil falling from the crack at the top, Gu Ji couldn't help but think of the two rounds of water he saw all over the ground in the underground fire control room.

It is important to know that one of the causes of subsidence is the extraction of underground fluid resources.

For example, oil, natural gas, groundwater, etc.; In the 20s of the 20th century, Xia's Huzhou, Jinzhou and other places were induced by the concentrated exploitation of groundwater in urban areas, and the North China Plain also caused large-scale land subsidence due to groundwater falling funnels.

Gu Ji is still unable to determine the specific cause of this natural disaster.

Once it is really related to the fluid, then it is very likely that you will encounter groundwater backflow when you fall into the pit!

"Squeaky ......"

As he was analyzing the crisis, a few subtle cracks drifted into his ears.

"Bai Dong be careful!"

The sixth master raised his head and shouted, and immediately pulled Bai Maoliang to the side.

And Gu Ji seemed to have his eyes raised above his head, and he didn't even look at it, but his outer ears were slightly dilated, and he slid back to dodge.

Bang!

A boulder fell from the ceiling overhead, and along the huge triangular crack, a large amount of black and wet dirt fell down, and soon piled up into a half-human-high dirt bag.

Bai Maoliang got up at a loss and immediately looked at Gu Ji.

"Wang Xueming, is this place going to collapse, we have to leave quickly!"

"Don't worry Bai Dong, this is just the deformation of the concrete structure caused by the vibration of the secondary building, the ceiling is covered with a large number of steel bars, there is a strong tension, and it can't collapse for a while......

Gu Ji said as he leaned over again and picked up a handful of soil that had just fallen, and the humidity was even greater than before.

About fifteen minutes.

There was a rush of footsteps in the fire staircase, and a thug leaned against the door frame and shouted:

"Oh no, Bai Dong, the water, the basement is full of water, and it has flooded to the 6th floor of the building!"

"What!?"

Bai Maoliang's face changed, there was really a wolf in front of him and a tiger in the back, he had just finished solving the warlord faction, but he didn't expect to encounter a flood again.

Now they have not found their way out, and when the water does not come up, will they not be drowned alive?

"Wang Xueming, what should I do now, is there a way to get out as soon as possible?"

"Yes, there is, but it depends on how well Mr. Chen collects their tools......

Gu Ji replied, but his eyes fell on the countdown of the level in the upper right corner.

When he went to the basement fire control room, the water had just barely reached the floor, and now more than four hours later, it had already poured into the fifth floor, and it would take nearly a day to flood to the top floor.

The premise is that the backfill rate is always the same.

"Do you know the speed of flooding?"

"This ...... I don't know, Brother Kai just asked me to come up in advance to report the news. ”

"You go down and make a mark, pinch it with your phone's stopwatch, how long does it take to cross a meter, come up and report every half an hour!"

"What are you doing! Don't go yet! ”

Seeing that the thug was staying where he was and scratching his head, Bai Maoliang was so anxious that he went up and kicked it directly.

Half an hour later, the thug came back again, his face obviously panicked, and it was a little difficult to breathe.

"The water has reached the 8th floor, almost 4 minutes a meter!"

"How did it suddenly change so fast? Wouldn't it take just over 6 hours to get here?! ”

The sixth master was also so frightened that his heart tightened, as if a cold snake had crawled up his back.

Gu Ji raised his head and stared at the broken ceiling, the speed of the water flooding was much faster than he expected, and it seemed that the second subsidence had accelerated the backfilling.

Cold sweat oozed from Bai Maoliang's forehead, like an ant on a hot pot, anxiously walking back and forth in the office, walking faster and faster, and asking a few words from time to time.

But Gu Ji's answer is: without tools, it is impossible to guess the time of self-help.

"Why hasn't this Chen Jianhe come back yet!"

"It's coming! Here it comes! ”

Just when Bai Maoliang was on the verge of eruption, a chaotic sound of footsteps finally came from the corner of the building.

The fat-headed and big-eared Chen Jianhe walked in with a group of group executives and employees, holding various building materials and tools in their hands.

Thanks to the fact that this guy is the manager of the real estate department, otherwise it would not be easy to find these things quickly in the ruins of the building and in the extremely dark conditions.

"Brother Wang, do you think these things can be used?"

"Okay, you go and bring a big table."

Gu Ji picked up a few steel pipes, took out two of them, used iron wires to pass through the hollow inside, connected them together, and then wrapped them with tape a few times at the seams to fix them.

Wait for the staff to move the table over.

He stepped on it and came to the bottom of the crack.

Looking at the cracks that were still dropping mud from time to time, Bai Maoliang's eyelids jumped wildly, and he was a little worried.

"Wang Xueming, what are you going to do, don't collapse the roof!"

"Don't worry, Bai Dong, I'm just going to try the depth of being buried."

As he spoke, Gu Ji inserted the steel pipe into the soil, and Pan Xinli on the side saw that he was a little struggling, so she also jumped on the table to help.

With the sparse soil, the two steel pipes were finally inserted into the dirt, "Give me two more." ”

Chen Jianhe blinked, a little dazed.

"Brother Wang, don't you want to use these steel pipes all the way to the ground?"

"What's the problem?"

Gu Ji lowered his head while wrapping the tape and replied, this was the easiest method they could achieve at the moment.

"Although I don't have much knowledge, I also know the relationship between soil solidity when digging foundations, and under normal circumstances, the thicker the soil layer, the greater the soil bulk density, and the harder and denser the soil."

"Aside from the possibility of hitting a slate along the way, as the steel pipe goes deeper, the shear, compression and friction of the soil will increase, and the force required will increase exponentially!"

Perhaps it was related to his own field, Chen Jianhe straightened his back, and his tone was preachy.

Bai Maoliang also seemed to be a little skeptical.

Gu Ji's expression was very calm.

"Manager Chen is right, but you have overlooked one point, soil hardness is mainly determined by soil texture, capacity and water content, of which water content has the greatest impact; The higher the water content, the higher the soil compressibility, the lower the strength, the softer it is, and I didn't ask you to find a jack! ”

As he spoke, he plunged a third steel pipe into the dirt.

Chen Jianhe immediately took up a handful of soil, gently pinched it, it was indeed very wet, nodded at Bai Maoliang, and finally smiled awkwardly.

"Brother Wang is so knowledgeable, it's my old Chen Banmen who got the axe."

"Hurry up and help!"

Bai Maoliang saw that this method was feasible, so he urged the group's senior management and employees to get started together.

After a while, Gu Ji inserted four steel pipes into the soil, and when it was the turn of the fifth, the manpower gradually became a little overwhelmed, as if he had reached something.

This is also the situation that worries him the most.

And the employees on the side kept panting one by one, and even Bai Dong and Liuye, who were not working, were breathing louder and louder, and it seemed that the oxygen in the building was gradually running out!

Gu Ji immediately arranged for his subordinates to bring the jack and put it at the bottom of the steel pipe.

"Hold on to the junction, be sure to hold it steady!"

Everyone nodded.

As Gu Ji pressed the mechanical rod, the steel pipe continued to drill upwards into the soil, although it was very slow, but at least little by little, at the same time, there was still a lot of muddy water flowing down the steel pipe and the wire.

Fifth and Sixth ......

Until the seventh pipe is added.

There was a "purr", and the employee in charge of holding the steel pipe suddenly felt a loose sensation in his wrist.

"Brother Wang, the steel pipe seems to be through!"

Gu Ji hurriedly removed the jack and pushed it upwards hard, but the steel pipe really didn't have any resistance.

So he hurriedly lay on the table and looked up along the mouth of the steel pipe, but it was a pity that it was dark inside.

Bai Maoliang's eyes lit up.

"Alright?"

"One step away."

Gu Ji pulled the wire up and down, and with the sour friction, a lot of dirt and black water remained, until the wire could move freely in the pipe wall, he put his mouth up and took a sip.

A strong, rotting earthy smell filled the mouth, but it didn't have the feeling of stuffing the chest before.

It's fresh air!

"It's through, Bai Dong!!"

"Really!?"

Bai Dong, who was fanning the wind, picked up the employees, came to the bottom of the steel pipe, and after feeling the air flow, he hurriedly took two breaths.

Other high-level officials were also excited, and some even approached the steel pipe directly and shouted:

"Is there anyone outside?"

"Help!"

"We're buried in the ground!"

……

Gu Ji put his ear on the steel pipe and listened carefully for a while, except for the wind and some noises, there was no response.

"It's useless, it's such a small hollow, it's hard to hear outside."

"So what do we do next?"

Bai Maoliang just asked this sentence.

There were a lot of footsteps behind him, and Brother Kai and the Korean army also led people to the top floor of the building, there were about seventy or eighty people, some of them were injured and supported each other, some were crying with joy, and some were bowing their heads and panicking.

And those who panicked were afraid of being killed by the warlord faction, and chose to no longer support the Bai family's employees.

Yang Chen naturally also noticed those subordinates.

Now that he is in power, he naturally can't wait to vent this resentment immediately, "Bai Dong, these people are all greedy for life and afraid of death, and betrayed the Bai family!" ”

"I, I didn't!"

"Director Yang, Bai Dong, give me a way to live!"

……

Several employees fell to their knees and began to beg for mercy.

Just when Bai Maoliang waved his hand and was about to let Kaige and the Sixth Master kill them, Gu Ji opened his mouth to stop them.

"Bai Dong, now is not the time to kill them, the water has already overflowed the eighth layer, we don't have much time to waste, if we want to get out as soon as possible, we need a lot of manpower."

"You say, what should I do now!"

"It's easy, dig!"

Gu Ji pointed to the crack on his head, "The length of each steel pipe is one meter, which means that we are now six and a half meters away from the ground, this depth is not high or low, but fortunately, there are enough of us." ”

"The crack is wide enough for two adults to go in, because the soil has a high moisture content and is so soft that we can easily dig with our arms, and the other person is responsible for building the inner wall to prevent landslides, and as long as the building doesn't shake anymore, in less than three hours, we can dig a pipe to the ground."

"Good! Just do as you say! ”

Bai Maoliang now completely regarded Gu Ji as his only hope for survival, and turned his head to command the group of employees who had just come up, "Did you all hear clearly?" As long as you are willing to do what you are ordered, I, Bai Maoliang, promise that after you go out, you will be exempted from the punishment of betraying the Bai family, and I will not be held accountable! ”

"I heard you all!"

"Thank you, Bai Dong!"

……

As soon as they heard that they didn't have to die, these employees refused to work hard, and immediately jumped on the table one by one to prepare for excavation.

Gu Ji hurriedly stopped them.

"Digging is very simple, the important thing is to prevent landslides, Manager Chen, the people in your real estate department know more about civil engineering, you must be optimistic about them, every half a meter deep, you must use your hands to compact the surrounding soil, and use plastic boards, wooden boards, etc., and fix them with iron wires or steel pipes."

"I know, isn't it the 'plug-in method'!"

Chen Jianhe foamed, rolled up his sleeves and began to instruct his men to prepare the plates.

Seeing that the crowd was busy, Bai Mao had a sense of security in his conscience, and couldn't help but praise.

"Wang Xueming, you are really an all-rounder, I didn't expect to know so much knowledge, what did you do before?"

"I have worked in the Myawaddy Army before, and I have worked in the mine for a few years when I came to Jinyuan Group, so I have a clear understanding of these soil knowledge."

Gu Ji casually rammed.

In an illegal enterprise like Jinyuan Group, it is impossible for a miner to have time to learn so much knowledge.

All of the methods he used were self-help methods in the "Military Disaster Prevention Manual".

Theoretically speaking, the methods of self-rescue after the earthquake are extremely limited, mainly relying on external government rescue, and what he can do is first to keep his breathing unblocked, which is one of the reasons why he struggled to channel the steel pipe out of the ground.

Most of the fatalities in geological disasters are 58% due to suffocation.

Then it is to find a way to transmit signals to the outside world, and if the transmission is ineffective, you can only treat wounds, collect water and food, and ensure the stability of your own life activities.

And Gu Ji has been doing these things since he woke up from the ground.

The Korean army listened to the change of gaze, not knowing what he was trying to write.

More than two hours later.

Under the joint supervision of Gu Ji and Chen Jianhe, a mud road more than five meters long was dug up that could accommodate two people.

But as the channel gradually lengthens upwards, so does the slump pressure from both sides.

The iron wire steel pipe shelf that was finally fixed will still fall down due to the soil sliding, causing a landslide, and the oxygen in the building is now all connected by this steel pipe, so the employees have not eaten for most of the day, and the more they dig back, the slower the speed.

"Boom la la ......"

At this time, the employees who leaned into the stairwell faintly heard the sound of water washing.

The thug who was in charge of monitoring the water level rushed in, his shoes completely soaked with blisters.

"Bai Dong, Brother Wang, the water has not entered the 31st floor!"

"What!?"

"Didn't you say that it would take four or five hours to reach the top, and it was only half of the time!"

"Hey! Can the top one dig quickly! The water has been poured in! ”

"Oh my God, we're not going to drown here, are we?"

……

Hearing the news, everyone in the office panicked instantly, staring at the fire staircase one by one, desperately urging the employees who dug the passage.

Bai Maoliang's complexion changed suddenly.

He snatched the pistol from the waist of the sixth master and aimed it at an employee who was stuck in place because of fear, bang!

The employee was shot in the leg by Bai Maoliang, and instantly fell off the table, clutching his thigh and screaming.

The muzzle of the gun was raised again, startling the crowd one by one.

"Dig it out for me right away! Otherwise everyone will die! ”

"Hurry! Bai Dong has spoken, give me more strength! ”

Chen Jianhe shouted desperately, constantly wiping the sweat from his forehead, and he was also afraid to death in his heart.

Gu Ji didn't expect Bai Maoliang to be in such a hurry.

My eyes rolled, and I suddenly had an idea.

"Bai Dong, the water level is rising too fast, with the current digging speed, it is difficult to guarantee that there will be no accidents, I remember that there seems to be a portable oxygen mask under the medical department, I can go down and get it, just in case!"

"Really?"

When Bai Maoliang heard this, he was overjoyed.

But the sixth master on the side said: "The 30th floor has been submerged, even if you remember the location of things, you will inevitably take a detour to find it in extremely dark light conditions, and you have to carry things, this back and forth oxygen consumption is not something that ordinary people can bear, unless you have received special freediving training." ”

Freediving training, in addition to extreme sports and professional diving players, is only trained by the Navy or special forces.

But Gu is just an army mercenary in Myawaddy.

If you say that you can dive freely at this time, it will definitely arouse suspicion.

But he didn't panic at all, took off his backpack, and took out the portable fire breathing apparatus selected by the system reward from it, "This is the equipment I got from the elimination control room, the general theoretical use time of the 6.8L respirator is 40 minutes, and the actual use time is about half an hour, which is enough for me to retrieve things." ”

"Great! Go and come back quickly! Liuzi, you go with you to help. ”

"Yes!"

Looking at the sixth master who came over following Bai Maoliang's order, Gu Ji squinted.

I can't imagine this old guy being so cautious.

It's all come to this point, and he still has to find someone to watch him.

That's right.

Gu Ji took the initiative to propose to go to the medical department to get an oxygen mask, in fact, it was to explore the side mission, but even if someone followed, he didn't panic, anyway, this sixth master couldn't get into the water.

However, he couldn't trust the Bai family's thugs, so he called Chaojun and Pan Xinli to help him pull the safety rope.

Coming to the staircase on the 31st floor, the water level has risen to the second section of the building.

Gu Ji took off all the equipment, only kept a strong light flashlight, and put the portable respirator on his body, in fact, the structure of this thing is very simple, it is an orange reflective vest, on which two gray high-pressure gas cylinders similar to large bottles of Coke are fixed, and a hose is connected to the breathing mask.

The North Korean army tied a safety rope around his waist.

"Be careful!"

"Don't worry."

Gu Ji grinned, and after making an "OK" gesture, he immediately "poofed" and entered the water.

Gollum......

The groundwater quickly poured into his ears, cutting off his hearing, and at the same time, it was pitch black in front of him, and he had to face the underwater pressure in all directions, this extreme environment made his heart rate rise, his nerves tensed, and he subconsciously began to breathe rapidly.

Fortunately, I used to swim a lot when I was in college.

He turned on the strong flashlight, as a professional firefighting equipment, waterproof, dustproof and high temperature are essential elements, with light, physiological tension is immediately relieved a lot.

In order to find a darkroom before, he had carefully looked at the detailed layout of the 30th floor, and naturally knew the location of the oxygen mask.

So Gu Ji now has plenty of time to look for it.

"Wait, why is the ceiling height a little short in this location......"

I didn't find it when I walked down before, but when I was floating on the roof of the shed and swimming, Gu Ji found that I needed to keep going downstream, and the roof seemed to have an inclined angle.

So he swept the light along the roof of the shed, found a crack, and kicked it hard, but the cement brick did not move.

It is too difficult to exert power underwater, and oxygen is wasted.

Gu Ji could only find another way.

He arrived at the office on the lowest floor from the top of the shed, where the filing cabinet had shifted as the water washed away, revealing a security door with a combination lock on it.

Fortunately, because of the deformation of the building, the security door was squeezed open a crack in the door.

It's not easy to exert force outward, but it's different when you have a point of borrowing.

Gu Ji pinned the flashlight to his waist, stepped on the wall, grabbed his hands through the crack in the door, pulled it outward, tried two or three times, only to hear a "snoring", accompanied by a few bubbles floating out, the door finally opened!

He swam in the door and pulled out his flashlight.

Suddenly, a miserable white face appeared in sight, which scared his back and couldn't help but have goosebumps!

[Side Goal: Finding the 30th Floor Darkroom Successfully!] 】

[Open the Hidden Target: Find the Hidden Secrets of the Jinyuan Group!] 】

Gu Ji had forgotten the prompts of the system for a while, but was attracted by the three corpses floating in front of him, they were all male, tall, naked, with bloodshot eyes, looking fierce and vicious.

Strange as it may seem, the cause of their death was not to be killed by the earthquake rubble or drowned.

But.

Cannibalism!

Yes, the bodies of the three were covered with various wounds, either by shards of glass from the instrument in the throat or by the back of the head with an iron object.

The scariest thing is.

The expressions of several people were very weird, especially with a cruel and perverted smile on their mouths!

Outlaws!

This was the first instinctive thought that flashed through Gu Ji's mind.

[If you find a special item, do you want to exchange it for Crisis Points!] 】

There is one more level that is over, and 62,000 are owed
