At the beginning of the fire to save people, I was broadcast live as a firefighter

within the research group.

The number of researchers has already expanded from the original 6 to 12.

The two groups of people continued to conduct data analysis and model predictions.

"366 meters, the advancing speed is maintained very well."

"After all, there are three shifts, and everyone is doing their best. The speed can still be guaranteed."

"Currently there is no problem with the support of the top of the tunnel, but..."

The researcher hesitated to speak, but someone next to him immediately said what he dared not say:

"But now there is an ingenious force balance in the center of the tunnel. Once the tunnel is dug, without the support of the surrounding earth, rocks and rubble, it is likely to cause this force balance to collapse."

"Why don't we dig it out first? Build a pipeline along the wall of the cave to deliver necessary living supplies to the trapped people?"

"This method really works!"

"You are worried that digging will cause the force balance of the tunnel to collapse, so wouldn't it be okay to build a pipeline?"

For those who put forward their opinions, the researchers argue that:

"The risk factor of dredging at least one pipeline is far lower than digging the entire tunnel directly."

The researcher who made the rebuttal was a little speechless, and what the other party said was indeed true.

At this time, a person came out to smooth things over:

"Okay, old grandson, don't worry."

"I know your father-in-law is trapped inside, and your wife and mother-in-law have urged you many times."

"But things like rescue can't be rushed for a while. Once you are in a hurry, all kinds of problems are easy to appear. Do you understand?"

"not me....."

Sun Chengxu was a little speechless, his father-in-law was indeed trapped inside.

But this is not the reason why he wants everyone to dig directly.

This is mainly because he is worried that if the balance of force in the center of the tunnel is damaged due to the dredging of the pipeline, the structure will collapse.

Then it is too late for everyone to break through the tunnel and rescue people.

When something goes wrong, everyone will not even have a chance to rescue them.

However, if the tunnel is opened directly, even if something goes wrong, most of the people inside can be rescued.

Sun Chengxu sighed, and finally retreated.

Because he had already seen strong doubts in the eyes of the people around him.

Since everyone thought that they wanted to come out to their father-in-law in a hurry, they raised such objections.

So as long as you don't put forward a final argument, you can't convince others at all.

After all, other people have preconceived it, and they want to bend the law for personal gain.

It is very difficult to reverse this concept.

Sun Chengxu lowered his head helplessly.

On the morning of the fourth day, it was the 4rd hour since the tunnel collapsed.

inside the tunnel.

A boy about seven or eight years old curled up in his mother's arms.

His lips were pale, and his face had an unnatural bluishness.

"Mom, I'm hungry."

"Xiaohao, hold on, the uncle firefighter will come to rescue us soon."

"Mom, uncle firefighter, how long will it be before he comes to rescue us?"

"Soon, soon, they agreed for 4 days, now is the fourth day, they will not lie to us."

"mom....."

The child wanted to say something more, but the woman covered his mouth.

"Don't talk, close your eyes and rest for a while, talking will waste energy, and we don't have any mineral water to drink."

At this point, most of the people in the tunnel are in pretty bad shape.

Although it was just distributed last night, the last food.

But that's just two biscuits per person.

Two biscuits would not even count as afternoon tea in normal times, but now it turned into a regular meal.

Not to mention adults, even children are panicked with hunger after eating.

At this time, Cao Guoqiang was so hungry that his eyes were dizzy, and his lips were dry and cracked.

Because compared to the hunger of other people, he has not touched a drop of water for a whole day.

After all, he and many others made a joint promise to give his water to those 32 kindergarten children.

Therefore, all of them relied on a bottle of water for a full 83 hours.

He looked at Ah Chao, who was debugging the radio station, and felt a little nervous.

After hesitating for a while, Cao Guoqiang still said:

"Are you sure?"

A Chao didn't look up, nervously checking the circuit he reset step by step.

This modification was done without outside guidance and help.

He completed it entirely by relying on his previous electrician knowledge and the modification skills taught by the radio station.

So, to be honest, he really has no bottom.

"Do your best and obey the destiny."

Hearing the simple six words that Ah Chao said, Cao Guoqiang felt mixed feelings.

It is true that the other party is just a young man who has just finished his sophomore year. If he can do what he is doing now, he really can't expect too much.

His chapped lips squirmed slightly, and he murmured in a low voice:

"Do your best and obey the destiny."

After another ten minutes, Ah Chao checked all the circuit designs for the third time, and he let out a long breath:

"Okay, do you want to drive now?"

Cao Guoqiang nodded slightly without hesitation, his dry throat had already made it impossible for him to speak easily.

A Chao's finger rested lightly on the red switch button.

He had pressed this button thousands of times before, but this time it felt completely different to him.

At this moment, Ah Chao felt that the red button in front of him was not the switch of the police radio, but the start button of Big Ivan.

Live or die, win or lose depends on this.

He took another deep breath and pressed the switch with his fingers.

click.

The red switch button lights up, and a burst of electric current is heard from the police radio.

The sound of electricity lasted for three or four seconds, just when everyone thought the modification had failed.

A long-lost, pleasant female voice came from the police radio.

"Current tunnel excavation progress: 382 meters, and there are still 45 meters to reach the central area after sonar detection."

"We have set up a temporary base station at the entrance of the tunnel, and the trapped people can try to get in touch with the outside world through their mobile phones."

"..."

The volume of the police radio was not loud, but it could be heard far away in the dead silence of the tunnel.

The trapped masses who were dizzy from hunger heard this familiar voice.

One by one, they jumped up from the ground as if they had been beaten with chicken blood.

"The radio...the radio is ready!"

"Woooo...I just realized that this young lady's voice is really nice!"

"Great, we can go out in 45 meters!"

"Thank you to the country, thank you to the government, saying that 4 days is 4 days, it is really awesome!"

"I thought I was going to die here!"

"I must confess my love to Zhong Yuting after I go out!"

"I'll resign when I go back. I work overtime all day and night, and I haven't enjoyed anything!"

"Now I understand what it means to walk around the ghost gate!"

However, the joy of everyone did not last long.

Just listen to the radio broadcast and continue to play the news.

"..."
