"There's still one step left."

Gu Ji pulled the iron wire up and down, and there was a sour friction feeling, and a lot of mud and black water remained. When the iron wire could move freely inside the pipe wall, he put his mouth up and took a sip.

A strong rotten earthy smell filled the mouth, but the previous feeling of tightness in the chest was gone.

It's fresh air!

"It's clear, Mr. Bai!!"

"real!?"

Director Bai, who was fanning the air, pushed aside the employees and came to the bottom of the steel pipe. After feeling the air flow, he hurriedly took two puffs.

Other senior executives were also extremely excited, and some even approached the steel pipe and shouted:

"Is there anyone outside?"

"Help!"

"We're buried underground!"

…

Gu Ji put his ear against the steel pipe and listened carefully for a while. Except for the sound of wind and some noise, there was no response.

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

"Then what should we do next?"

Bai Maoliang just asked this question.

There was a large number of footsteps behind them. Brother Kai and Chao Jun also led people to the top floor of the building. There were about seventy or eighty people. Some of the people in the group were injured and helped each other, some cried with joy, and some lowered their heads in panic.

And those people who are panicking are the employees who are afraid of being killed by the warlords and choose not to support the Bai family anymore.

Yang Chen naturally noticed those subordinates.

Now that he is in power, he naturally wants to express his resentment right away, "Dr. Bai, these people are all greedy for life and fear of death, and they betray the Bai family!"

"I-I didn't!"

"Director Yang, Director Bai, please give me a way to survive!"

…

Several employees knelt down and began to beg for mercy.

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

"Dr. Bai, it's not time to kill them yet. The water has already reached the eighth floor. We don't have much time to waste. If we want to get out as soon as possible, we will need a lot of manpower."

"Tell me, what should we do now?"

"It's easy, dig it!"

Gu Ji pointed to the crack above 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 high or low, but fortunately there are enough of us."

"The width of this crack can accommodate two adults. Because the soil has high moisture content and is soft, you can easily dig the soil with just your arm strength. The other person is responsible for building the inner wall to prevent collapse. As long as the building no longer shakes,

In less than three hours, we can dig a pipeline to the ground."

"Okay! Just do as you say!"

Bai Maoliang now completely regarded Gu Ji as his only hope for survival. He turned around and directed the group of employees who had just come up, "Did you all hear it clearly? As long as you are willing to do as ordered, I, Bai Maoliang, promise that after we get out,

I will spare you the punishment for betraying the Bai family and will never be held accountable!"

"I heard everything clearly!"

"Thank you, Dong Bai!"

…

As soon as they heard that they were not going to die, the employees were still unwilling to sacrifice their lives. They immediately jumped on the table to prepare for excavation.

Gu Ji hurriedly stopped them.

"Digging is very simple. The most important thing is to prevent landslides. Manager Chen, the people in your real estate department know better about civil engineering. You must pay attention to them. Every time you dig half a meter deep, you must compact the surrounding soil with your hands and use plastic boards and wooden boards.

Once it's attached, fix it with 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 men to prepare the boards.

Seeing the crowd getting busy, Bai Mao felt 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. What did you do before?"

"I worked in the Miaowadi Army as a civil defense officer before, and then worked in the mines for a few years when I came to the Jinyuan Group, so I have a relatively clear understanding of these soil knowledge."

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 used were all self-rescue methods in the "Military Disaster Prevention Manual".

Theoretically speaking, self-rescue methods after the earthquake are extremely limited, and they mainly rely on external government rescue. The first thing he can do is to keep his breathing smooth. This is one of the reasons why he struggled to remove the steel pipe channel from the ground.

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

Then we need to find a way to transmit the signal to the outside world. If the transmission is ineffective, we can only treat the wound, collect water and food, and ensure the stability of our own life activities.

And what Gu Ji has been doing since he woke up from the subsidence is these things.

Chao Jun's eyes changed as he listened, and he didn't know what he was thinking of writing.

More than two hours later.

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

But as the channel gradually extends upward, the collapse pressure from both sides becomes larger and larger.

The iron wire and steel pipe racks that were finally fixed would still fall off due to slipping soil, causing landslides. In addition, the oxygen in the building now depends entirely on this steel pipe. The employees did not eat for most of the day. The further back they dug, the faster they went.

slow.

"Crash..."

At this time, the employees who were leaning into the stairwell vaguely heard the sound of water rushing.

The thug responsible for monitoring the water level hurried in and his shoes were completely soaked with water.

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

"What!?"

"Isn't it said that it will take four or five hours to reach the top of the water? Only half of that time has passed!"

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

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

…

After hearing the news, everyone in the office panicked instantly. Everyone stared at the fire stairway with their eyes wide open, desperately urging the employees who were digging the tunnel.

Bai Maoliang's expression changed suddenly.

He grabbed the pistol from Mr. Liu's waist and pointed it at an employee who was stunned 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 in agony.

The muzzle of the gun was raised again, frightening everyone in the crowd like quails.

"Dig it out for me immediately! Otherwise everyone will die!"

"Hurry up! Director Bai has spoken, please give me more strength!"

Chen Jianhe shouted desperately and kept wiping the sweat from his forehead. He was scared to death.

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

I rolled my eyes and suddenly had an idea.

"Dr. Bai, the water level has risen too fast. With the current digging speed, it is difficult to guarantee that no accident will occur. I remember that there seems to be a portable oxygen mask under the medical department. I can go down and get it in case of emergency!"

"real?"

When Bai Maoliang heard this, he was overjoyed.

But Mr. Liu on the side said: "The 30th floor has been flooded. Even if you remember the location of things, you still have to take detours to look for them in extremely dark light conditions, and you have to carry things. This consumes a lot of oxygen.

It is not something that ordinary people can bear, unless you have received special freediving training.”

Free diving training, apart from extreme sports and professional divers, is only done by the navy or special forces.

But Gu Ji was just an army mercenary from Myawaddy.

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

But he didn't panic at all. He took off his backpack and took out the portable fire respirator selected by the system as a reward. "This is the equipment I got from the fire control room. The 6.8L respirator generally has a theoretical use time of 40 minutes. In practice,

About half an hour, enough time for me to get my things back."
