crisis management game.

Chapter 91 The Secret of the Chamber of Secrets

Four dead at once?
If it wasn't that brother Kai who killed him, something must have happened in the building!
Combined with the wet soil falling from the cracks on the top, Gu Ji couldn't help but think of the water that he saw all over the ground in the underground fire control room during the two rounds.

It should be known that one of the causes of subsidence is the extraction of underground fluid resources.

For example, oil, natural gas, groundwater, etc.; in the 20s, Xiazhou, Jinzhou and other places caused subsidence due to the intensive exploitation of groundwater in the urban areas, and the North China Plain also caused large-scale land subsidence due to groundwater sinking funnels.

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

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

"Squeak..."

Just as he was analyzing the crisis, several small crackling sounds floated into his ears.

"Bai Dong is careful!"

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

And Gu Ji seemed to have swollen eyes on the top of his head, he didn't even look at it, just slightly expanded his outer ears, and then slipped back to dodge.

Boom!

A huge boulder fell from the ceiling above his head, and along the huge triangular crack, a large amount of black and wet soil fell down, and soon piled up into a bag half the height of a person.

Bai Maoliang got up in a daze, and immediately looked at Gu Ji.

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

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

As Gu Ji said, he leaned down again to pick up a handful of soil that had just fallen, and the humidity was even greater than before.

About 15 minutes or so.

There was a rush of footsteps coming from the fire escape stairs, and a thug held the door frame and shouted:
"It's not good, Bai Dong, the water, the basement is full of water, it has flooded to the sixth floor of the building!"

"what!?"

Bai Maoliang's complexion changed. It was true that there were wolves before and tigers behind. He had just finished solving the warlord faction, but he did not expect to encounter floods again.

Right now they haven't found a way out, and when the water doesn't come up, won't they be drowned alive?

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

"Yes, but it depends on how Mr. Chen and his tools are collected..."

Gu Ji answered with his mouth, but his eyes fell on the checkpoint countdown in the upper right corner.

When he went to the fire control room in the basement, the water had just submerged the floor, and now more than four hours later, it has already poured into the fifth floor. In simple conversion, it will take nearly a day to flood the top floor.

The premise is that the backflow rate remains constant.

"Do you know the speed of Shuiman?"

"This... I don't know, brother Kai just asked me to report in advance."

"You go down to make a mark, pinch it with a stopwatch on your phone, how long it takes to cover one meter, and report back every half an hour!"

"What are you doing in a daze! Hurry up!"

Seeing that the thug was scratching his head in place, Bai Maoliang was so anxious that he went up and kicked him.

Half an hour later, the thug came back again, with a look of panic on his face, and it was difficult to breathe.

"The water has already flooded to the 8th floor, one meter in about 4 minutes!"

"Why did it suddenly change so quickly? Wouldn't it only take more than 6 hours to flood here?!"

Liu Ye was also so frightened that his heart tightened, like a cold snake crawling up his back.

Gu Ji raised his head and stared at the broken ceiling. The speed of the water overflowing was much faster than he expected. It seemed that the second ground subsidence accelerated the backflow.

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

Ke Guji's answer is: Without tools, it is impossible to predict the time of self-rescue.

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

"I'm coming!"

Just when Bai Maoliang was on the verge of erupting, there was finally a burst of chaotic footsteps from the corner of the building.

Chen Jianhe, with a fat head and big ears, walked in with a group of senior executives and employees of the group, 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 a building full of ruins and under extremely dark conditions.

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

"Okay, you guys go and move a big table over here."

Gu Ji picked up a few steel pipes, took out two of them, passed the iron wire through the hollow interior, connected them in series, and then wrapped a few rounds of tape around 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 crack where mud was falling from time to time, Bai Maoliang's eyelids twitched wildly, and he said worriedly.

"Wang Xueming, what are you doing, don't bring down the roof!"

"Don't worry, Bai Dong, I'm just trying to see how deep I will be buried."

As he said that, Gu Ji inserted the steel pipe into the soil. Pan Xinli, who was at the side, saw that he was struggling, so she also jumped on the table to help.

Accompanied by the sparse soil, the two steel pipes were finally inserted into the soil, "Give me two more."

Chen Jianhe blinked, a little dazed.

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

"is there a problem?"

While wrapping the tape, Gu Ji lowered his head and answered, this is the easiest way they can achieve so far.

"Although I, Chen Jianhe, don't have much knowledge, I also know the relationship between the degree of soil firmness when digging foundations. Generally speaking, the thicker the soil layer, the greater the soil bulk density, and the harder and denser the soil."

"Aside from the possibility of encountering stone slabs in the middle, as the steel pipe continues to deepen, the soil shear force, compression force and friction force you will suffer will become greater and greater, and the required force will increase exponentially!"

Perhaps it was related to his own related fields, Chen Jianhe straightened his back, and his tone had a sense of preaching.

Bai Maoliang also seemed a little skeptical.

Gu Ji's expression was very calm.

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

While speaking, he inserted the third steel pipe into the soil.

Chen Jianhe immediately picked up a handful of soil, squeezed it lightly, it was indeed very moist, nodded at Bai Maoliang, and finally smiled awkwardly.

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

"Hurry up and help!"

Seeing that this method was feasible, Bai Maoliang urged the group's senior management and employees to do it together.

After a while, Gu Ji inserted four steel pipes into the soil, and when it was the fifth steel pipe's turn, the manpower gradually became too much, as if it had hit something.

This is also what worries him the most.

And the employees at the side kept panting, even Bai Dong and Liu Ye, who were not working, were breathing louder and louder. It seemed that the oxygen in the building was gradually running out!

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

"You stretch out your hands to support the connection, be sure to hold on!"

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 it was advancing bit by bit. At the same time, a lot of muddy water continued to flow down the steel pipe and the iron wire.

The fifth root, the sixth root...

Until the seventh steel pipe is added.

With a "snoring", the employee in charge of holding the steel pipe suddenly felt a loosening of his wrist.

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

Gu Ji hastily removed the jack and pushed it upwards, the steel pipe did not have any resistance.

So he hurriedly lay down 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.

"Is that all right?"

"One more step."

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

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

It's fresh air!
"It's over, Director Bai!!"

"real!?"

Dong Bai, who was fanning the wind, pushed aside the staff and came to the bottom of the steel pipe. After feeling the airflow, he took two quick breaths.

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

"Is there anyone out there?"

"Help!"

"We're buried underground!"

……

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

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

"Then what shall we do next?"

Bai Maoliang just asked this sentence.

There were a lot of footsteps behind him, and Brother Kai and Chaojun also led people to the top floor of the building. There were about 80 to [-] people. Some of these people were injured and supported each other, some were crying with joy, and some were panicking with their heads down.

And those people who panic are afraid of being killed by the warlord faction, and choose not to support the employees of the Bai family.

Yang Chen naturally also noticed those subordinates.

Now that he is in power, he naturally wants to express his grievance immediately, "Bai Dong, these people are greedy for life and afraid of death, and betrayed the Bai family!"

"I, I didn't!"

"Director Yang, Director Bai, give us a way out!"

……

Several employees knelt down and begged for mercy.

Just when Bai Maoliang waved his hand to let Kaige and Liu Ye kill them, Gu Ji stopped him.

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

"Tell me, what should I do now!"

"It's very simple, 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. Fortunately, we have enough people."

"The width of this crack can accommodate two adults. Because the soil has a high water content and is soft, it is easy to dig the soil with only arm strength. The other person is responsible for building the inner wall to prevent collapse. As long as the building does not shake anymore, In less than three hours, we can dig a pipe to the surface."

"Okay! Just do as you say!"

Now Bai Maoliang completely regards Gu Ji as his only hope for survival, and turned his head to direct the group of employees who just came up, "Did you all hear clearly? As long as you are willing to follow the order, I, Bai Maoliang, promise that after going out Exempt you from the punishment for betraying the Bai family, and you will never be held accountable!"

"I heard everything clearly!"

"Thank you Dong Bai!"

……

As soon as they heard that they didn't have to die, these employees were still unwilling to work hard, and one by one immediately jumped onto the table and prepared to dig.

Gu Ji hurriedly stopped them.

"Excavation is very simple. The most important thing is to prevent landslides. Manager Chen, the people in your real estate department know more about civil engineering. You must take good care of them. Every half a meter deep, you must compact the surrounding soil by hand, and use plastic boards, wooden boards, etc. Wait for it to stick, and fix it with iron wire or steel pipe."

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

Chen Jianhe spat, rolled up his sleeves and began to direct his subordinates to prepare the plates.

Seeing the crowd moving, Bai Maoliang felt a sense of security in his heart, 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 worked in civil defense in the Miaowadi team before, and worked in the mine for several years when I came to Jinyuan Group, so I have a clearer understanding of these soil properties."

Gu Ji was talking nonsense.

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

The methods he adopted are all self-rescue 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. The first thing he can do is to keep breathing unimpeded, which is one of the reasons why he struggled to get the steel pipe out of the ground.

Most of the deaths in geological disasters, 58% are suffocation deaths.

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

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

Chaojun's eyes changed as he listened, not knowing what he was thinking of writing.

More than two hours later.

Under the joint supervision of Gu Ji and Chen Jianhe, a dirt road more than five meters long and able to accommodate two people was finally dug out.

But as the channel gradually lengthened upwards, the collapse pressure from both sides also increased.

The iron wire steel pipe shelf that was finally fixed will still fall due to the slipping of the soil, causing landslides. In addition, the oxygen in the building is now connected by this steel pipe, and the employees have not eaten for most of the day. The further they dig, the faster the speed slow.

"Crash..."

At this time, the employees leaning into the stairwell vaguely heard the sound of water washing.

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

"Bai Dong, Brother Wang, the water has already entered the 31st floor!"

"what!?"

"Didn't it take four or five hours to submerge to the top, and only half of the time has passed!"

"Hey! Can you dig up the top quickly! The water has already been poured in!"

"My God, we're not drowning here, are we?"

……

Hearing this news, everyone in the office panicked in an instant, staring at the exit of the fire stairs with their eyes wide open, desperately urging the employees who were digging the tunnel.

Bai Maoliang's complexion changed suddenly.

He snatched the pistol from Master Liu's waist and pointed it at an employee who was stunned because of fear, bang!
The employee was shot in the leg by Bai Maoliang, and fell off the table in an instant, holding his thigh and screaming continuously.

The muzzle of the gun was raised again, scaring the crowd like quails.

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

"Hurry up! Director Bai has spoken, please work harder!"

Chen Jianhe yelled desperately, kept wiping the sweat from his forehead, and was terrified to death.

Gu Ji didn't expect Bai Maoliang to be so anxious.

Turning his eyes, he suddenly had an idea.

"Bai Dong, the water level has risen too fast. With the current digging speed, it is difficult to guarantee that no accidents will happen. I remember that there seems to be a portable oxygen mask under the medical department. I can go down to 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 find detours in extremely dark light conditions, and you have to carry things. The oxygen consumption of this trip is very high." It's not affordable for most people, unless you have special freediving training."

In free diving training, except for extreme sports and professional diving players, only the navy or special forces will be trained.

But Gu Ji was just an army mercenary of Myawaddy.

If you say you can free dive at this time, you will definitely be suspicious.

But he didn't panic at all, took off his backpack, and took out the portable fire breathing apparatus selected by the system, "This is the equipment I got from the fire control room. The 6.8L breathing apparatus generally has a theoretical use time of 40 minutes. About half an hour, long enough for me to get my stuff back."

"Great! Hurry up and come back! Sixth son, you follow along to help."

"Yes!"

Looking at Liu Ye who came over following Bai Maoliang's order, Gu Ji squinted his eyes.

Unexpectedly, this old guy is so cautious.

At this point, 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 for the detection of side missions, but even if someone followed him, he didn't panic. Anyway, this sixth master can't get into the water.

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

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

Gu Ji unloaded all his equipment, leaving only a bright flashlight, and put a portable respirator on his body. In fact, the structure of this thing is very simple. It is an orange reflective vest, and two gray high-pressure gas cylinders similar to large bottles of Coke are fixed on it. , leads to a hose connected to the breathing mask.

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

"Be careful!"

"Do not worry."

Gu Ji grinned, made an "OK" gesture, and immediately entered the water with a "plop".

Gollum...

Underground water quickly poured into his ears, isolating his hearing, and at the same time, it was pitch black, and he had to face the underwater oppression in all directions. This extreme environment made his heart rate rise, his nerves were tense, and his subconscious was rushed Breathe.

Fortunately, Gu Ji often swam in college.

He turned on the bright flashlight. As a professional firefighting tool, waterproof, dustproof and high temperature resistance are all necessary elements. With the light, the physiological tension was immediately relieved a lot.

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

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

"Wait, why is the floor height of this location a bit short..."

I didn't notice it when I was walking below, but when I was floating and swimming on the roof, Gu Ji found that I needed to keep going downstream. The roof seemed to be inclined.

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

It is too difficult to exert force underwater, and it also wastes oxygen.

Gu Ji could only find another way.

He came to an office at the shortest height from the roof of the shed. Due to the washing of the water, the position of the file cabinet was moved, and a security door was exposed at the rear end, and the door was equipped with a combination lock.

Fortunately, due to the deformation of the building, the anti-theft door was squeezed open a crack.

It is not easy to exert force outward, but it is different if there is a point of leverage.

Gu Ji pinned the flashlight on his waist, stepped on the wall, grabbed it with both hands through the crack of the door, and pushed it out forcefully. He tried two or three times, only to hear a "snoring", accompanied by a few bubbles floating out, and the door opened. Finally opened!
He swam through the door and took out his flashlight.

All of a sudden, pale human faces appeared in sight, scaring him so much that his spine shuddered, and he couldn't help but get goosebumps!
[Sub-question goal: successfully find the 30th floor dark room! 】

[Open the hidden target: Find the hidden secrets of the Jinyuan Group! 】

Gu Ji had temporarily forgotten the system's prompt, but was attracted by the three corpses floating in front of his eyes. They were all male, tall and big, completely naked, their eyeballs were covered with bloodshot eyes, and they looked menacing.

Strange to say, the cause of their death was not crushed by earthquake debris or drowned.

Instead.

Cannibalism!

Yes, the bodies of the three people were covered with various wounds. They were either stuck in the throat by shards of glass from the instrument, or were injured on the back of the head by iron objects.

The most terrifying thing is.

The expressions of several people are very strange, especially the cruel and perverted smile on their mouths!

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