Kong Minxing said: "When I was in a hurry, I already felt that the sunshine on the grassland was much longer than that of our Lizhuang, and the climate was drier, which was conducive to growing cotton. Pen, fun, pavilion www. biquge。 info In addition......" Kong Minxing looked at his feet and said with a smile: "Cotton can improve the soil quality, and it is not picky about the soil quality, but it has higher requirements for wind, sunshine, and rain, and is afraid of insect pests." Most of these lands in front of you are saline-alkali land, it is inconvenient to grow grain, but it is a good thing to grow cotton, there is sufficient sunshine, and there are fewer pests and diseases. ”

Zhang Han was stunned for a moment when he heard this.

Sure enough, there are rules and doorways that outsiders don't understand, and today all the way to the west, I originally asked Kong Minxing to see where the boundaries of the fertile fields were, and then Li Shenming and Sun Jingting also had their own intentions, but who expected that the fertile fields near the water were not as good as the saline-alkali land of the hills here, which really made Zhang Han completely unexpected.

"Where's Brother Chuyang?"

After talking about the cotton field, Kong Minxing was open-minded and felt high-spirited.

In Zhang Han's here, doing things is a big cause of more than one million acres, and even related to the pattern changes of the entire Ming cotton production and cloth textile industry, everything is related to the national economy and people's livelihood of the entire Ming Dynasty, and even in Zhang Han's words, it affects the trend of history, this sense of achievement is not comparable to a jinshi in the examination, at this time Kong Minxing is even a little lucky, fortunately he was not able to enter the examination, otherwise, now he is not a petty official in the sixth department, or he takes the imperial history, and does those useless impeachment and folds in the procuratorate, Either it is put on the local magistrate and the county, no matter where it is, what he does is definitely not as important as that of Zhang Han, and it makes Kong Minxing have a sense of achievement.

The mind changed, but it was found that something was wrong, the five of them went out together, and they came to the door together, just now Sun Yuanhua seemed to be still here, but everyone said that the matter of the cotton field was invested, and after half a ring, they found that Sun Yuanhua was gone.

"There are guards." Zhang Han smiled: "I'm not afraid that he will be bitten by a wolf." ”

"Speaking of which, I saw a wolf when I first went up the mountain." Sun Jingting frowned and said: "There are not many guards, and they are mainly scattered on the periphery to prevent Tartars, so Sun Chuyang doesn't really want anything to happen." ”

Sun Yuanhua is the treasure of the Military and Political Department, but in the same system, no one present really thought that this technical nerd who was not inferior to the world would be eaten by the wolf.

Everyone immediately scattered to look for it, and Zhang Han asked the guards standing on the periphery again, only then did he know that Sun Yuanhua had gone down the mountain alone.

"Sun Chuyang is like this......" Kong Minxing smiled bitterly: "He must not be interested in the topic, so he went down the mountain by himself." ”

The mountains here are extended, the soil is also a large area of saline-alkali land, weeds and shrubs are grown, it is really difficult to find someone, everyone slowly descends the mountain, several guards keep shouting Mr. Sun, Jiang Yi and others on the periphery heard the movement, and also rode horses to look for it.

Everyone felt a little crying and laughing, it was Zhang Han's meaning to come out like this, it was a tour of the territory he had just beaten down, and what came out was the identity of a friend and a partner, Zhang Han did not regard it as a friend of his subordinates, and as a result, he followed Sun Yuanhua, a Leng Touqing, speaking of which, this guy is a master of military science, a master of miscellaneous studies, a master of weapons, or a serious disciple of Xu Guangqi, a great master, and an official of the imperial court, but he did things so casually, it was simply speechless.

"Here, I've found it."

Several guards rode around on horseback, and at the end of the day, at the foot of a hill in the east, they saw Sun Yuanhua.

Everyone rushed over angrily, and saw Sun Yuanhua squatting on the ground from a distance, not knowing what he was messing with.

"Sun Chuyang, what the hell are you doing." It was difficult for others to speak, so Kong Minxing stepped forward and said angrily: "Leave quietly, what are you going to do here." ”

"What are you talking about cotton, cloth, cotton fields," Sun Yuanhua raised his head, rolled his eyes and said: "I don't understand, and I'm not interested, so I came down and walked around at will." ”

Kong Min said angrily: "Then you should always say it." ”

"I'm not a three-step child." Sun Yuanhua said unconvinced: "Besides, I came out to take a look, but I really made a big discovery." ”

Zhang Han took a step forward and asked, "What big discovery?" ”

Sun Yuanhua stood up, holding a yellow stone in his hand, and said: "This mountain range, I look like it is rich in copper deposits, come out and walk around, and sure enough." Half of this stone in my hand is copper ore. ”

Zhang Han's expression moved, and Sun Jingting immediately turned his head and said, "Jiang Yi, ask someone to fetch a bucket of water!" ”

Li Shenming said: "What do you do with water? ”

Kong Min said: "If this stone is really chalsy ore, after being soaked and cleaned in water, the stone will be 'bile', which is enough to prove that this mountain range, a lot of bare ore, if you mine here, you will get twice the result with half the effort." ”

"It's great." Li Shenming rubbed his hands and said, "This is really an unexpected gain. ”

"What kind of accident is this?" Sun Yuanhua said proudly: "It's me here, this matter is not an accident, originally I planned to explore the mineral deposits around here." ”

Zhang Han and the others were stunned when they heard this, and then they all laughed.

After a while, Jiang Yi and others brought a bucket of water, and Sun Jingting personally put the bare stone in it to clean, and after only a short while, half of the stone turned green.

Sun Jingting stood up, and said with a very complicated expression on his face: "It's a shame that I'm still a person from a mine, and when I came to this kind of mountainous area, I didn't expect to send someone to explore, even if it wasn't a copper mine, it was very likely that there would be iron ore or something else." ”

Indeed, this area is connected by mountains, and it is very likely that this terrain will produce mineral deposits, but of course it is very likely that there will be nothing but mountains made of rocks.

In the hinterland, the mineral deposits that are easy to find and exploit under the existing conditions have been organized and officially mined since 2,000 years ago, and now all kinds of mineral deposits in the Ming Dynasty that are easy to mine are being mined, and only some mineral deposits that are not easy to find and are not easy to mine must be discovered and mined by a special team in later generations.

Of course, the people present did not know that the copper reserves in Jining were very large, and after the exploration of the Inner Mongolia Autonomous Region in later generations, it was found that there were more than 500,000 tons of reserves, ranking second in the autonomous region.

Zhang Han immediately said: "Jiang Yi, immediately send Tangma to inform the people of the Military and Political Department, and ask them to transfer more technicians here to carry out large-scale exploration projects!" ”

"Yes, sir."

Everyone present was overjoyed and excited.

"I'm going to see a few other mountains." Sun Yuanhua said at this time: "There must be a large amount of ore underground, but it is best to find out first, there are not many shallow ores that are easy to mine, and whether this mountain range is a huge copper mining area." ”

"There is labor." Zhang Han arched his hand and said solemnly: "This time it is really sincere, we and Yusheng are not lacking, and we are indeed the most lacking in copper, which is really a big problem." ”

The main reason for the lack of copper in the Ming Dynasty is that the imperial court is not developed enough, mining, especially China's copper mines have experienced thousands of years of mining, there are generally few shallow ore layers that are easy to mine, and they all need to lay deep wells, with vertical shafts, inclined shafts, hard roadways, inclined roadways to enter personnel and drainage, mining is not easy, the cost is very high, and the most important thing is that a mine has at least tens of thousands or even hundreds of thousands of miners, it is not easy to manage, and the management level of the Ming Dynasty can only be said to be stronger than Meng Yuan, which is far worse than the Han and Tang Dynasties. It was thrown off a hundred streets by Zhao Song, it was not easy to mobilize, difficult to manage, and the cost was high, which led to the copper mining of the Ming Dynasty was very backward, not only the lack of copper for the people, but also the copper reserves of the imperial court were seriously insufficient.

Insufficient copper reserves, resulting in the lack of copper coins among the people, there is no huge amount of copper coins, the people once returned to the barter trading method, and then the silver reserves were enough, the people began to use a large number of silver, the disadvantages of using silver are much greater than copper coins, but the Ming court has never understood this, let alone taken it to heart, the people's copper reserves have been very little, only maintained at a very low level.

If the copper ore reserves in front of him are very high and easy to mine, it will undoubtedly be a great benefit to Zhang Han and He Yusheng, at least the copper parts needed for casting cannons, the copper parts needed by sea ships, and the copper parts needed by various machines, these do not have to be searched for everywhere and then transported back.

If the quantity is large enough, you can also sell copper materials or mint copper coins yourself, and the Ming Dynasty can't help but mint money privately, which is also a great source of wealth.

Before dark, Sun Yuanhua, who looked tired, came down from several other mountains, his head was covered with weeds from drilling shrubs, and his body was also full of yellow and gray soil traces, looking at Zhang Han and others, this nerd clapped his hands, and actually smiled with satisfaction: "Good news, these nearby mountains contain a large amount of copper ore, and most of them are shallow ore layers that are easy to mine. ”

Zhang Hanwan smiled, Li Shenming slapped his face, Sun Jingting's face also showed excitement, Kong Minxing was proud and relieved in his smile, no matter what, Sun Yuanhua is also a disciple of the teacher, and the achievements in miscellaneous studies made him discover the existence of copper mines as soon as he arrived here, the teacher is a pedantic man, he and Sun Yuanhua can both make a career, and thousands of years later, there may be people who praise the name of the teacher!

Five days later, Li Dongxue and Wang Debang of the Military and Political Department and others rushed over, and Han Laoliu from Lingqiu also rushed over, Cai Jiu is now in the Zunhua New Iron Yard, where he has invested more than 100,000 taels of silver, recruited a lot of miners, needs to be screened, trained, and a new blast furnace, some of the old furnaces are in use, and some are to be rebuilt or repaired, Zunhua Iron Yard was originally a government-run iron yard, after the official iron yard stopped, there are also some small-scale iron yards in operation, and now of course they are all eaten by He Yusheng, Cai Jiu and they are in Zunhua to reopen up, although they have produced pig iron, they are still very early from the scale and output of the real Lingqiu.
