The wife was happy, and Ma Cheng was so happy that she hurriedly invited the medical officer to confirm the diagnosis. She was undoubtedly happy.

Ma Cheng laughed happily, and was confused. He smiled foolishly for a while before remembering to ask someone to notify his father. So the Admiral's Mansion was in an uproar. The old father and second mother came over to ask about their well-being, and they were very nervous. The marquis of Kaiyuan were also restless.

He told Er Niang to guard nowhere in the mansion, and double the number of people who serve each other in person.

The lady was happy, and the whole Kaiyuan was filled with joy, and the people and the morale of the army was greatly boosted.

Ma Cheng was in a very comfortable mood. This child came too timely and the family was peaceful. Thanks to the pretty lady of Li Zhengming's family, otherwise Yu Fengjun, who was confused, would be confused and confused. When he remembered, he couldn't help laughing. This era

This kind of knowledge is too poor. His wife, a spoiled lady in the official family, wouldn't she know how to have a child? When she met Wang Zhen in person, she praised her for a few words, and then gave her a label that she could be in the Admiral's Mansion.

Free in and out.

After Wang Zhen was beaten away, he still admired him, Li Haoyun, Li Haoyun, is really a lucky person, even his pretty lady is filled with joy.

The Admiral's Mansion was really jubilant for a few days, and the morale of Kaiyuan was greatly boosted.

At night, in the room.

Ma Cheng helped his wife sit down and personally fed a bowl of white porridge. The pregnancy reaction was indeed the case. Yu Fengjun could only use some white porridge and often vomited. Inside and outside the room, twenty or thirty

A maid served Yu Fengjun and protected him as a kind of cherished animal.

Putting his smooth chin on his husband's shoulders, Yu Fengjun's heart was sweet and solid as he had never felt before.

I sighed sadly again, it turns out that I am also a philandering woman? Is I happy? Is Fanghua Yingxue competing for favor with my wife? I cried again when I thought about it. Ma Cheng's shoulders were wet, and he couldn't be hurried.

Comfort, I was really stupid for three years after one pregnancy. There was no reason to cry if I said that I could cry. I hurriedly hugged Feng Junshimei and coaxed her to make me happy and sweated all over.

It would be too tiring to let Li Zhengming's wife accompany him tomorrow.

In late autumn, Yu Fengjun, who gradually showed his feelings, became more and more full and more elegant.

Something happened at this time, forcing Ma Cheng to leave his pregnant wife temporarily and go to deal with it. A prospecting team discovered a gold mine in North Korea. According to historical records, the Goryeo gold mine was mainly produced to the north of the Yalu River and north of Pyongyang.

, the output in 1936 was 17,000 kilograms. Most of them were in the quartz veins where gneiss and granite were connected. The yield was Yunshan gold mine, followed by Changcheng Foren gold mine and Dayu.

Dong Gold Mine, 30% gold mine. In addition, there is Sui'an Gold Mine on Xihai Road in North Korea and Jishan Gold Mine on Yangguang Road.

The gold mine discovered this time was in Yunshan, North Korea. Mao Wenlong urgently reported Kaiyuan and had strictly blocked the news.

Macheng only knows that there are many gold mines in island countries, Japan and North Korea are rich in gold. This is a very important matter. Macheng has to deal with it in person. The wealth is moving. How valuable is a gold mine? It is enough to change some

Historical progress, this is a real gold mountain. I left my pregnant wife for a while and walked on the mountain road to Shanhaiguan, went from Shanhaiwei to Pi Island, and took a calm weather to North Korea.

News of the discovery of the gold mine was strictly blocked, and the mine was also under the strict protection of Mao Wenlong’s personal military camp.

Hurry up to Yunshan. In the densely guarded mountains and forests, Ma Cheng was frightened by the exquisite mining skills of the Ming craftsmen. Mao Wenlong entrusted Li Dan to hire a large number of craftsmen from Jiangnan to dig mining caves. Yunshan, Korea in late autumn, is now a

At a large construction site, the craftsmen hired by Jiangnan adopted an extremely advanced method of burning and blasting to mine hard and dense quartzite-style ore in the belly of Yunshan Mountain.

The craftsmen first dug a tunnel at the entrance of the mine cave, and used the burning method to mine gold on the rock wall three to five meters away from the tunnel.

The method of burning and explosion used by the Ming Dynasty craftsmen is to first set up a simple stove according to the location of the ore veins and the height of the tunnel wall, and put fire charcoal into the stove, make the fire burn, wait for the stone wall to be heated, and pour cold water to make the stone wall form due to thermal expansion and contraction.

The semicircular artificial joint surface. The ore will peel off naturally or collapse after manual prying, greatly improving the working efficiency.

To put it bluntly, it is to use the principle of heat fluctuation and cold shrinkage to heat the ore first and then pour cold water on it, and the ore will fall off naturally, which saves great time and effort. Ma Cheng was amazed by this. Who said that the Ming Dynasty did not have the soil for natural science breeding? These smart craftsmen

Although I do not understand the principle of heat rise and cold contraction, I put this principle into practical use, which is the wisdom of the Ming Dynasty.

At Yunshan Gold Mine, craftsmen used 300 keel water trucks to drain water.

When mining is burned, the naturally formed cold and hot air convection inside and outside the cave can achieve the purpose of natural ventilation of the mine cave. The mined ore depends entirely on manpower and is sent out of the cave through a platform made of fir.

Therefore, this requires a large labor cost and requires the support of the North Korean royal family.

Yunshan gold mine is about to be mined in large quantities, and Macheng has gained a deep understanding of this, which has caused the dispute between the mineral tax between the Ming Dynasty and the ministers. How much benefit does it involve? The Donglin Party must abolish the mineral tax at all costs. It is conceivable that it will abolish the mineral tax at all costs.

What huge benefits are involved in this.

When the Ming Dynasty was founding, most of the mines were mined by the imperial court, and a small part were mined by powerful private individuals.

During the reign of Taizu, Chengzu was in charge of the imperial court. Until the time of Emperor Yingzong, a large number of private mining sites appeared among the people, and even had private armed mines. In the third year of Emperor Yingzong's Zhengtong period, the mine owners in Jiangnan made a fuss in order to compete for the mines.

The records of fighting and even using private armed forces were recorded in the record of Emperor Yingzong. In the tenth year of Zhengtong, silver mines were discovered in Yunnan, and the eight villages in Yunnan fought armed forces to compete for silver mines.

Therefore, when did the gold and silver mines in the Ming Dynasty begin to be exploited by the people in the Zhengorth of Emperor Yingzong?

Jiangnan has many mines. Who dares to do this so-called civilian armed mining? We need to ask the national hero Yu Qianyu. After the Tumu Fort Incident, the national hero Yu Qianyu appeared in Jiangnan.

A crazy armed mining tide, the mine owners have private army fighting to fight for mines, and countless casualties are killed or injured. Such a terrible thing, you can imagine who was digging the corners of the Ming Dynasty, and how much benefit it involves. The scholars of the Ming Dynasty

He was so unscrupulous that he occupied and mined the imperial court, and even pointed at the emperor's nose for the sake of hundreds of thousands of taels of mine tax every year. If you dare to collect the mine tax, you are competing for profit with the people.

A large-scale armed mining wave appeared in a Central Plains dynasty, which was extremely absurd.

The wealth is moving, and the Yunshan Gold Mine is quickly mined. On the first day of mining, it earns 25 kilograms of gold. The heat in the eyes of the people around me made Ma Cheng frightened. This is the powerful power of gold. Twenty-five kilograms

Two taels of gold are obtained from ore. An adult miner can mine at least twenty-five kilograms of ore every day. What is the concept of two taels of gold? Two taels of gold is equivalent to twenty taels of silver. Calculated based on the rice price of the capital of the capital in the third year of Chongzhen, two taels of gold are calculated.

If you buy one stone of rice for silver, two taels of gold, you can buy ten stones of rice. How much is ten stones of rice? One thousand two hundred kilograms of rice. What is the income of a miner in Yunshan for a day can buy one thousand two hundred kilograms of rice!

This is the result of the severe drought in the north and the high price of rice for bandits. If it is converted into the price of goods in the Wanli period of Emperor Shenzong, a stone of rice can be sold for seven cents of silver, and a 2 tael of gold can buy three thousand kilograms of rice! What an amazing wealth this is, no wonder it is
