After arranging the various processes of gasoline refining and the various processes of fire and thunder manufacturing, Fang Xu walked easily and happily. Pen ~ fun ~ pavilion www.biquge.info

Xu Zhong, who followed beside him, asked, "Lord Jianzheng, do you only let the craftsmen rush to make these ordinary things?" His Majesty's will is to make firearms with different characteristics suitable for all kinds of war occasions. ”

Fang Xu glanced at him and said, "Except for the craftsmen who have made simple and crude firearms in the Benhou army, they are all a group of beginners, do you expect them to run away if they don't know how to stand?" ”

Fang Xu took Liu Renliang and Xu Zhong's two followers to the iron workshop.

I only heard that in the iron workshop, several old craftsmen were frowning, and the small craftsmen bowed their heads one by one...... Uh, stunned.

Fang Xu asked very cheaply, what is going on with you, sighing one by one.

The craftsmen didn't know Fang Xu, but they had all seen Liu Renliang and Xu Zhong, the two young eunuchs.

Xu Zhong is still very qualified as an official, and when he saw this situation, he knew that everyone didn't recognize Fang Xu, so he immediately stepped forward and said: "This is our firearms supervisor, Master Fang, you haven't come to see you yet." "Confucian scholars, farmers, industrialists and industrialists have been talking for thousands of years, even in the open Tang Dynasty, the status of craftsmen is very low. When everyone saw Fang Xu's power, they immediately knelt on their knees.

As a former socialist four-good youth, as for the four good, hehe. Fang Xu was still not used to kneeling and bowing, so he called everyone to get up. He continued, "Are you in trouble?" ”

Although Fang Xu's attitude was very gentle, the craftsmen were still very restrained, and when everyone heard Fang Houye's question, an old craftsman replied: "If you go back to your lordship, it is difficult to increase the furnace temperature, and it is difficult to completely refine iron and other things. ”

Hearing them say this, Fang Xu has a bottom.

Why is it so difficult?

Burning wood, the temperature is indeed not reached, but, as a college student after a thousand years, Fang Houye does not know how to burn coal?

As far as Fang Xu knew, the large use of coal was a matter of the Song Dynasty, and coke appeared in the Southern Song Dynasty, and it was used in large quantities after the Yuan Dynasty. It is said that when Marco Polo in the West saw the Chinese using coal, he thought it was a "black stone" that could be burned. But that's hundreds of years away.

Later, Fang Xu once saw on the Internet that the Western Han Dynasty was the earliest period of coal mining and use in China. It is dark in color and resembles a stone.

Fang Xu confidently said to the old blacksmith, "The problem of furnace temperature will be solved for you. ”

Speaking of coal, I am afraid that in later generations, Shanxi will be the first thing to think of. In fact, Shaanxi is also a large coal-producing province, and Shanxi's coal is famous for its shallow quality.

Shaanxi is one of the important coal industrial bases in later generations, with a total coal-bearing area of about 57,000 km2 and a cumulative proven resource of 170 billion tons, ranking third in the country in terms of retained resources. The main coal resources can be divided into five major coalfields, namely the Jurassic coalfield in northern Shaanxi, the Carboniferous Permian coalfield in northern Shaanxi, the Triassic coalfield in northern Shaanxi, the Permian coalfield in Weibei and the Jurassic coalfield in Huanglong, which are often mentioned in geography textbooks in junior high school.

Moreover, there are a large number of shallow coal mines in the vicinity of Chang'an, which is just right for the Tang Dynasty people who have very little mining technology.

As for the manpower issue, there is no need to think about it, the fourth battalion of Tongshan has manpower.

Just do it, it's not easy to move, and the provincial procrastination is a crime, and I don't know if it's dragged until the Year of the Monkey.

Immediately said to Liu Ren: "Lao Liu, go find a map of Chang'an and the surrounding areas, and call Li Sanshou to go out with the master to play a wave, and ask Li Sanshou to bring more people." ”
