In the eighth year of Chongzhen, April 13.

Daming, Shanxi, Zezhou Mansion.

In Jincheng County, Wolonggou Coal Mine.

This semi-open-pit coal mine is a new mine contracted by miner Hu Wenting from Xujiazhuang at a preferential price of 150,000 silver yuan.

The total reserves of high-quality anthracite coal exceed 100 million tons, and the average burial depth is about 100 meters, but there are also reserves of more than millions of tons, and the burial depth is only 10 meters to 20 meters, or even shallower, so the mining value is very high, and the cost of digging out can be very low.

As for the Fengmingshan Coal Mine in Yi County, Shandong, although its potential reserves can be mined for another thirty or fifty years, the mining is becoming more and more difficult, accidents are becoming more and more frequent, and the cost performance is no longer very high, which makes Hu Wenting have to transfer most of his energy to Wolonggou and transfer a large number of manpower to come over.

Even so, there is still a disadvantage in the Wolonggou Coal Mine, that is, it is inland, and the transportation is not convenient enough, so it is necessary to let the transport convoy, loaded with coal and stone, pass through the Taihang Mountains more than 200 miles long, send it to the side of the Yellow River, and finally send these high-quality anthracite coal to Xujiazhuang Harbor City by river and sea.

The transportation distance increased by more than a thousand miles.

The cost has increased by more than 40%.

Even if it is still profitable, the profit margin is still not high, and it is not as profitable as the Fengmingshan coal mine.

Fortunately, the stone road built by Xujiazhuang has been built in Jincheng County, not far from the Wolonggou Coal Mine, and it can be passed in a few days, which can greatly save the transportation cost of land routes.

Secondly, it is to use explosives to open the mine, so that the shallow coal seam is exposed, and then directly open pit mining, which can greatly save mining costs.

These two are combined.

The coal excavated from the Wolonggou Coal Mine is not only profitable, but also profitable and profitable.

Hu Wenting has been leading the technicians to carry out the explosives mining test for almost two years, and has invested no less than 500,000 silver dollars, but the results achieved are very limited, and the return is less than 30,000 silver dollars, which can be said to be a blood loss.

The reasons are mainly twofold, one is that the cost of each bombing the mountain is very high, ranging from 5,000 silver dollars to tens of thousands of silver dollars, and it will be burned down with a bang.

Second, the use of explosives to open the mine, this is a very high-tech work, how to accurately control the amount of charge, how to bury the explosion point, how to calculate the explosion range, how to achieve the best explosion effect, all need to carry out a lot of mathematical calculations, not the real mathematical master, it is impossible to use the least amount of explosives, to achieve the best mining effect.

Hu Wenting is proficient in liberal arts, but his mathematical ability is obviously not good, and the mining experiments designed and arranged by him himself are not ideal every time, and they cannot achieve the most desired results.

That's when he discovered a genius.

Li Dingguo.

This boy, who is only 15 years old this year, has a very high talent in mathematics.

Some of the simpler math problems given to him by Hu Wenting can always be completed quickly and well, with an accuracy rate of 100%.

Later, I gave him some complicated quadratic and cubic formulas, and he was able to solve them quickly.

Slowly, Li Dingguo became a little assistant next to him, and even handed over some problems encountered in practical work, such as the calculation of the explosion range, to Li Dingguo to deal with, and every time he did not disappoint Hu Wenting, reducing a lot of his mental burden.

Satisfied.

Hu Wenting is becoming more and more satisfied with this smart and motivated young man, and plans to wait for him to have fuller wings, and then give him some opportunities to perform, and gradually cultivate him.

It was only when a large-scale bombing test failed, burning more than 30,000 silver dollars, and Hu Wenting's mood was extremely bad.

This clever young man jumped out extremely unwisely, pointed out several major mistakes in this test, analyzed the specific reasons, and said that if he could set up the bombing point according to his method, he would spend a maximum of 20,000 silver dollars to achieve the desired effect and mine the underground coal layers......

"What do you know?"

Hu Wenting was enraged and yelled at him, "You dare to talk nonsense here before your milk smells dry and your wings are not hard? How do I usually teach you, to guard against arrogance and rashness, not to be arrogant, and to consider the problems of the world too simply...... You don't have to say any more, don't come here in the future, and if you talk like this again, I'll send you back to Shandong and continue to dig in the mines!"

"Teacher, there is a saying that ambition is not in old age, only the courage to question can discover the truth, I think that teacher, your set of mathematical models, there are certain problems, do not make improvements at the principle level, even if you spend another 1 million silver dollars, you can't get the desired results, teacher, I Li Dingguo is insignificant, but I have burned a lot of money, and these money is not blown by the wind, it is the blood and sweat of countless miners, if I can reduce the loss, I will be punished no matter how big, and I am willing."

Li Dingguo did not flinch, and said righteously and strictly.

"What you said is righteous and awe-inspiring, do you want the whole world to know that I, a teacher, is not as good as you as a student, and I am narrow-minded, suppressing you everywhere, and not allowing you to have a chance to perform?"

Hu Wenting sneered, shaking his head in his heart, extremely disappointed, wasted, this young man is wasted, his concentration is so poor, his heart is so jumpy, he is impatient at the age of fifteen, no matter how smart such a person is? Only small wisdom and no great wisdom will not go far.

It can be said that as a Confucian businessman, Hu Wenting also has the Confucian characteristics of suppressing geniuses, of course, he doesn't think this is called suppression, the time has not yet come, and the opportunity is not yet ripe, and Confucianism pays attention to moderation, and has the saying that wisdom dies early, and there are many people who are too smart and miserable, so it seems to be suppression, but it is actually a kind of protection, and a genius who has not suffered a setback is not called a genius.

So Li Dingguo jumped out like this time, which not only made him feel angry, but also extremely disappointed.

"Teacher, I don't mean that, the "Oriental Times" said that now is the era of talents, but also the era of efficiency, sometimes it is not good to follow the step-by-step, you have to break the routine, you have to have the courage to try...... Teacher, please provide 5,000 silver dollars, no, 3,000 silver dollars, let me take someone to do a blasting test, if you fail, you are willing to accept any punishment, if you succeed, you don't need any reward, as long as the teacher is not angry."

Li Dingguo bowed his head and arched his hand, and said with a respectful look.

This attitude won the favor of other technicians, and they all helped him speak:

"Boss, what this kid said seems to make sense."

"Why don't you give him a chance?"

"I've already burned a lot of money, and another three thousand silver dollars won't be much."

But hear these persuasions.

Hu Wenting's face was even more ugly, he didn't even notice that Li Dingguo still had such a good popularity, so many people helped him speak.

"Yes, yes!"

He glared at Li Dingguo fiercely and said: "Boy, it seems that I still underestimate you, if you don't fulfill your wish this time, I can't get rid of this infamy of suppressing talents, okay, I'll give you a chance, give you a chance to prove you, and the three thousand silver dollars are not enough, I'll give you thirty thousand!" You really have the ability to blow up this mountain, and blow up all the coal underneath, but ......."

Hu Wenting said with a murderous face: "If you lose, go back to Shandong honestly, and then go down to the mine to dig a mine for a lifetime, and there will be no more future."

This moment.

Hu Wenting really moved to kill.

Even he himself was very surprised, didn't he always advertise himself as a Confucian businessman, why at this moment, he was so harsh on a fifteen-year-old boy, and he wanted to beat him into the abyss?

He doesn't know exactly what the reason is, it may be the deep responsibility of love, or it may not be, but at this moment, Li Dingguo, a young man, has reached a critical choice again, heaven on one side and hell on the other, of course, if he gives up immediately and sincerely apologizes to him, this is also the correct answer, Hu Wenting will feel that he is rotten and withered.

"Good! Thank you, teacher, I want to give it a try!"

Li Dingguo gritted his teeth and said, while Hu Wenting looked disappointed.

……

Rumble~

On the morning of April 13.

There was a shocking sound in Wolonggou, and then the ground shook violently like an earthquake, and nearly 100 tons of explosive materials exploded one after another like waves, blowing up a piece of mountain soil and rocks about three acres large and seven or eight meters thick, and it was soft and unbearable.

Then let the workers go over and dig it, and easily remove the soft soil, revealing the black coal seam below.

The experienced master, through the analysis of the proportion of rock formations, said with a look of surprise: "The coal seam in this open-air area is 18 meters thick, counting the area of nearly three acres, the coal and stone that can be dug out can be as much as 800,000 stones, worth more than 300,000 silver dollars, earning, making a big profit, this cannon bombing is beautiful, the explosion is extremely beautiful!"

The technicians were also very excited.

"It's done, this time it's finally done!"

"Eighteen meters of coal, it's a good mine."

"It's feasible, the explosives mining method is feasible, it can make money, this road is going to work!"

Take advantage of the opportunity for the technicians to cheer and celebrate.

Li Dingguo walked up to Hu Wenting's side, bowed his hand and said, "Teacher, in the hearts of your disciples, you will always be the teacher I am most grateful and loved, this experiment was successful, but the disciples still know that they have done wrong, if the teacher is still angry, please continue to punish the disciples."

"Hmph, you are now a great hero in the eyes of everyone, how dare I punish you?"

Hu Wenting still looked angry, but he sighed and said: "Hey, "Oriental Times" is right, the times have changed, many things are indeed outdated, you are not wrong, this time it is me who is wrong, this era is the era of young people, it is the era of geniuses, your blasting plan is far stronger than mine, this is a fact, it is a fact that cannot be denied, in the future, I will hand over all the blasting and mining to you, you take out your skills and blast more coal and stone for me."

"Teacher, I'm only fifteen years old, this ......" Li Dingguo was stunned, could he take on such a big responsibility?

"In addition, if you blow up the coal with explosives, you will be given one percent as a reward, Master Wang said that this open-pit coal field is worth 300,000 taels, then you will be rewarded with 3,000 taels, deducting the 500 taels of atonement silver you carry, and you will have to give you 2,500 taels, that is, you are now free and have made a lot of money." Hu Wenting said again.

"Am I free?" Li Dingguo was stunned, just like that, he regained his free body?

"Of course you're not free, so I trained you as a blaster, so you don't want to run away right away, do you?"

Hu Wenting glared at him and said, "You have to work in my mine for the rest of your life!" Of course, I won't treat you badly, and when the end of the year comes, you go back to Xuzhou with me, and I will introduce my 12-year-old daughter Xuanxuan to you, you are three years old, and you should be a very good match."

"What?!"

Li Dingguo's eyes widened, what does this mean, teacher, although it is very exciting to detonate nearly 100 tons of explosives, but he has no plans to work in the mine for the rest of his life, he still wants to see the outside world.

As for the teacher's daughter, I Li Dingguo was born in Liukou, am I worthy of it?

But Hu Wenting made up his mind not to let this kid run away, and he must be firmly bound and let him work hard for the Hu family's career for a lifetime - it can be said that at this moment, Hu Wenting is finally not a Confucian businessman, but like a qualified profiteer.
