Zheng Beiqi's thoughts are different from those here, he doesn't care about other people's opinions at all, he only cares about whether he and his wife can live well.

A hundred kilometers away from Shanxi, Zheng Beiqi heard that the soil there was suspected of iron ore. Let's go to Shanxi with Song Qingsong to have a look, if the estimate is correct, it may be a clay iron mine. At this time, there was not much iron ore development, and it was all controlled by the government.

There are also private mining, Kuang this thing, the initial investment is very large, once the mine owner mined it, it will be taken by local officials, in the name of requisition, take advantage of it. It does not give those businessmen who only have financial strength and no back-office support to survive. Therefore, in the Song Dynasty, few people mined this thing.

However, the amount of government mining is limited, and it is only maintained at a barely sufficient level.

Zheng Beiqi called Song Qingsong together, and when he came, he saved a lot of trouble by running the formalities from the government, and now, Zheng Beiqi does not have much money in his hand.

Zheng Beiqi didn't want to alarm the General's Mansion, not only did he not alarm, but he also kept it secret. This is the foundation for him and Yingxue to survive when they get out of the General's Mansion, that is, he quietly saves a sum of money, and moreover, he wants a large sum.

However, his ability to explore iron ore was enough for Song Qing to open his eyes.

Indeed, Song Qingsong believes that Qi Yunlong has guarded the general for many years, and he naturally has extraordinary insights. The Foundry Bureau of the military family seems to have a special understanding of the sensitive thing of iron.

When Zheng Beiqi talked to Yingxue, Yingxue was a little worried, if the iron mine was not out, if the iron mine was 、、、、、 the world here, it would be far darker than imagined, and Yingxue had heard a lot about the means of making money and killing people.

Unlike in modern life, where everything pays attention to formalities, here, it is the government and local officials who have the final say.

Yingxue's worries, Zheng Beiqi has also taken care of them in the past few days, hugged Yingxue, and comforted: "It doesn't matter if you mine iron ore, it's just a pile of stones in the eyes of people, we quietly smelt iron, integrate modern technology, and try not to let people see it." Digging the cellar and smelting iron underneath, there is no clue from the ground, and Song Qingsong has channels, pulls orders, produces finished products, and directly picks up the goods after inspecting the goods, all in secrecy. In the past few days, I have looked at the law, and it is not illegal, but I have some government behind my back, so that no one will be red and have evil hearts. ”

Zheng Beiqi said this, but thought in his heart, iron is easy to practice, if it can make steel, it will be a breakthrough. However, there are no chemicals, no sulfuric acid purification, and by the way, there are no high temperatures.

Coal, has not yet prevailed.

Shanxi, which is rich in coal mines. If, by the way, this mining a little coal mine, maybe there will be more gains.

Here to Shanxi two days of journey, riding a horse gallop, Zheng Beiqi only with his usual Chang Bao, Chang Bao This child is not very literate, but calm, seventeen or eighteen teenagers, through the calm that does not meet the age, and few words, occasionally pop up a sentence or two, all containing useful information.

Song Qingsong's grade is lower than Qi Yunlong's, so he has fewer days to face the saint, and he has an idle job, so he has a lot of time to be busy with other things.

Song Qingsong arrived in Shanxi earlier than Zheng Beiqi. Zheng Beiqi really couldn't stand the bumps on the horse's back all the time, he vomited twice, but fortunately, Chang Bao, the kid, mistakenly thought that the general's body had been subjected to family law and had not been able to make a good move, so he didn't think about anything else.

For most of the day's journey, Zheng Beiqi counted the time, endured all kinds of discomfort, and finally saw the post station before sunset.

At this time, the sunset is long, the mountains overlap in the clouds and mist in the distance, the scenery is pleasant, Zheng Beiqi thought, the air in ancient times is really good, you can see the mountains so far away, the ancient saying goes: see the mountains can also run dead horses, it can be seen that the clarity here is extremely high, there is no haze in the weather, it is really comfortable!
