At night, temperatures in Zambia can drop to around 10 degrees Celsius, in stark contrast to the high temperatures of the mid-30s during the day.

Lying in the makeshift tent, Zhao Guoyang felt cold on his body.

There is no way, because after coming to Zambia the day before yesterday, his speech shocked the audience, and Zhao Guoyang was pestered by Minister Toulouse every day for the past two days, and he couldn't go back to the embassy to rest.

After Zhao Guoyang waved his hand and determined the optimal rescue plan, the rescue operation at the mine disaster site has been officially launched.

In the past two days, the on-site staff successfully opened 4 small-caliber life-saving holes, and found some trapped people underground through holes 2 and 3.

At the beginning of the operation, such remarkable results have been achieved, and it is no wonder that Minister Toulouse has a blue eye for Zhao Guoyang.

However, after the opening of the small-caliber life-saving hole, new problems arose.

In the past two days, because the geological structure of the mine here is very complex, 300 meters from the surface to the roof of the underground roadway, there are topsoil layers, limestone layers, sandstone layers and gypsum layers.

In addition to the topsoil layer, the other three layers are mixed with limestone and have two aquifers, so that the problem of the drill bit being stuck in the borehole rescue hole has been many times, which seriously affects the progress of the operation.

At present, it is quite easy to open the small-caliber life-saving hole, but it is much more difficult to draw a gourd and open a large-caliber hole that is enough to put into the life-saving cage and rescue the trapped people below in turn.

At present, the two drilling rigs that have arrived at the rescue site in advance, the two drilling rigs of the American "Caterpillar" company and the Germanic "Liebherr" company, KBR360 and LBH200, have been proved to be unable to complete the task of opening this large-diameter life-saving hole.

And in the support teams of most African countries, including Zambia, Zaire and Nigeria, there is nothing comparable to these two drilling rigs.

As a result, the rescue effort was in a difficult situation.

During the day today, Minister Toulouse, who was sweating profusely, personally called the "African Countries Mutual Aid and Rescue Organization" and asked them for emergency support.

But unfortunately, the drilling rigs that meet the requirements are really difficult to find on the African continent, even if it is a "mutual aid and rescue organization of African countries", it is in vain.

As for the rescue teams that have been stronger, they are also a little helpless in this regard.

Needless to say, the two teams of the United States and Germany, "KBR360" and "LBH200", have the best performance among the drilling rigs of the two countries.

But even then, they have proven that there is no way to play a role at this mining disaster site.

As for the two products of Komatsu Manufacturing in the island country, although they are particularly unique in some aspects, they are still far from the two drilling rigs in terms of comprehensive performance.

Therefore, when the "Joint Command" discussed this issue during the day, Matsushiro did not mention this stubble.

The major powers are helpless about this, which makes Toulouse anxious.

After begging grandpa and grandmother to no avail to the captains and leaders of several rescue teams in the United States, England, and France, Toulouse could only ask for Zhao Guoyang again.

Thinking of Toulouse's sad face when he begged him in the morning, Zhao Guoyang had no choice but to agree to help him think of a way.

Seeing that Zhao Guoyang, an important person, agreed, Toulouse suddenly felt a little more vigorous, and even helped him arrange the tent next to the joint command center, so that he could contact the outside world at any time through the telephone of the command center.

At this time, Zhao Guoyang and Huaxia's rescue team lived separately, which was also based on this reason.

Thinking back to what happened during the day, Zhao Guoyang silently thought about what to do next.

The current situation is already relatively clear.

There must be no problems with his own rescue plan, and it has also been approved by rescue groups such as the United States and German.

Now that the small-caliber life-saving hole has also been opened, and the trapped people underground have also been contacted, the next step must be to find a way to save people.

According to the analysis of relevant geological experts, there is a large amount of groundwater below the mining site.

Its position is tens of meters higher than that of the trapped survivors.

In this case, if the large drilling rig cannot directly penetrate the limestone, sandstone and gypsum layers, or if the vibration is too large, it is easy to cause damage to the sandstone layer and loosen the surrounding groundwater, which can cause serious consequences.

Therefore, the biggest problem in front of Zhao Guoyang is to find a suitable drilling rig.

This drilling rig must not only have strong power, but also have enough stability to ensure the smooth and smooth implementation of the construction process.

It is so difficult to find such a demanding rig in a short period of time.

Even the technicians of "Caterpillar", one of the world's leading construction machinery companies, replied that it would take at least two months to redesign and prepare before they could come up with products that met the requirements.

Two months of design, plus production and transportation time, I am afraid it will take at least three months.

Even with the existence of the life-saving hole now, it is impossible for the people underground to survive for such a long time.

After all, the air content below is definitely insufficient, and when the carbon monoxide concentration is too high, it is likely to cause widespread casualties.

According to the speculation of life experts, the air in the underground can only last for a little more than a month according to the demand of seventy or eighty people, and this is still under the condition that the life-saving hole is kept ventilated.

The difficulty is now obvious, and let's see how to solve it.

Of course, the reason why Zhao Guoyang dared to agree to Toulouse was also because he had a certain amount of confidence.

His confidence lies in the new "SMS company".

In fact, what many people don't know is that "SMS Construction Machinery Group Company", as early as last year, has obtained 60% of the shares of "Daewoo Heavy Industries" and has become the actual controller of "Daewoo Heavy Industries".

And Zhao Guoyang, the chairman, personally holds 55% of the shares, and is the largest shareholder of "Daewoo Heavy Industries".

Therefore, many of the products of "Daewoo Heavy Industries" are now already products of "SMS Company" in terms of affiliation.

As the parent company, SMS has been engaged in technological interaction and joint development with Daewoo Heavy Industries.

It is as if the crane transported from Zaire before was jointly designed and researched by the two companies on the basis of a heavy-duty crane from "Daewoo Heavy Industries".

In the past year, the two companies have designed as many as five or six new products, and each of them has sold very well.

However, in the past year, whether it is "SMS Company" or "Daewoo Heavy Industries", there are no new products.

If you want to come up with a suitable product in such a short period of time, you can only rely on the old products of the "Daewoo Group" to improve.

I was going to think about it again and call Kim so-joo again. But Zhao Guoyang thought about it, and some things should be asked clearly.

So after tossing and turning for a while, he still felt that he would get up and go to the joint command center next door to make this call.

Zhao Guoyang just got up and went out, and he met the dusty Toulouse.

Noticing the coat worn by Zhao Guoyang, Minister Toulouse was stunned.

"Uh, Mr. Zhao, I was thinking about whether to wake you up, but I didn't expect you to wake up by yourself, it's great!"

After being slightly stunned, Toulouse hurriedly held Zhao Guoyang's hand, for fear that he would run away.

Zhao Guoyang smiled and said: "Mr. Toulouse, don't worry, we Huaxia people are the most important promise, and we will never be 'deserters'!

"Ah, that's great!" said Toulouse, nodding repeatedly.

After talking to this person for a few words, Zhao Guoyang explained his intention.

"That's right, Monsieur Toulouse, I've just thought about getting the big rig done first, so I've decided to give my business partner a call and ask her for help!"

Toulouse didn't expect Zhao Guoyang to take the initiative to mention this matter, and he was overjoyed at the time.

He grabbed Zhao Guoyang's arm and shook it violently: "Great, really good, Mr. Zhao! You want to make a long-distance call, right, then you go into the house and call, I'll help you guard outside!"

Seeing that the minister wanted to personally help him guard the door, Zhao Guoyang was a little ridiculous.

He shook his head helplessly and said, "Monsieur Toulouse, you can stay in the house." My call with my friend is nothing to be disregarded!"

"No, no, that's not what I meant!" Toulouse touched his smooth head in embarrassment, but did not move again.

Zhao Guoyang smiled softly at him, and then walked to the place where the telephone was placed.

After picking up the phone, Zhao Guoyang quickly dialed Kim so-joo's number.

"I'm Kim so-joo, who are you?"

Hearing the lazy voice of Miss Jin from inside, Zhao Guoyang's face became a little more gentle.

"Miss Xiuzhu, you went to bed so early, you guys, it's not eight o'clock yet, right?"

"Ah, Guoyang?" Hearing Zhao Guoyang's voice, Jin Xiuzhu was obviously a little happy.

"Well, it's me!" Zhao Guoyang smiled and responded.

"Guoyang, why are you free to call me today. Oh, I see, which of my subordinates did you buy off, and you know that I'm going to your Huaxia next month, right?"

Zhao Guoyang really didn't know anything about Jin Xiuzhu's plan, and he denied it slightly: "No, Xiuzhu." I'm calling you because I have something important to tell you, and I want to ask for your help!"

Hearing Zhao Guoyang say solemnly, Jin Xiuzhu was stunned.

However, she quickly reacted and said: "No problem, Guoyang, if you need help, just say it, I will do my best!"
