My Great Qin Cannot Die

The name of Jiugang is famous all over the world

In this life, Ying Zheng intends to use it. After all, there are no large iron ore veins in Guanzhong, or it is the land of Bashu.

But in the land of Bashu, the road is too difficult to walk. There is a road that is difficult to get to the sky, and he does not want to fight with nature.

Unless Shang Gongfang of the Great Qin Empire has researched something that transcends the era, it can easily get through the Shu Road.

Otherwise, it is far more convenient to seek iron ore veins on Da Yuezhi than Panzhihua and other ore veins in Bashu.

More importantly, in Li Kang's memory, there is another place above the land of the Da Yuezhi, which will be called Yumen in later generations.

There is a kind of oil resource here, which is also lacking in the Qin Empire.

What's more, capturing the Da Yuezhi would also allow the Da Qin Empire to expand its territory. Ying Zheng would naturally be happy to see such a thing that kills three birds with one stone.

After drinking a sip of tea, Ying Zheng instructed Xiao He, "Xiao He, I want to inspect the Pingcheng coal mine, you can arrange it here."

Hearing this, Xiao He's face changed slightly, he was a little surprised and even more helpless.

The first emperor was too self-willed, and he just wanted to come out one by one. When the first emperor inspected Yanmen County, he could ensure safety, but inspecting the coal mines of Pingcheng was too risky.

After all, it was inherently unsafe there, and people were killed almost every day. The most important thing is not only that the personnel situation is complicated, but also that the mines are extremely dangerous.

Thoughts flickered in his heart, Xiao He stood up, bowed deeply towards Ying Zheng, and said, "Your Majesty, the situation on the Pingcheng coal mine is complicated, and your Majesty's status is noble and should not be taken lightly."

"The son of a thousand gold, if you want to see the site of the Pingcheng coal mine, you can send Iron Eagle Ruishi there."

"If Your Majesty wants to see the officials and craftsmen above the Pingcheng coal mine, the minister can order them to come immediately."

At this moment, Xiao He glanced at Li Si, motioned to Li Si to persuade him, and then continued to move towards Ying Zheng, saying.

"Your Majesty, since all the coal mines in Pingcheng are mined by slaves, the scene is too cruel. Once His Majesty appears, these people may

Hearing this, Ying Zheng was silent for a long time.

He naturally knew that no matter who it was, he would basically not treat slaves as human beings.

What's more, the slaves sent from Shangtang County and Jiuyuan County were basically all prisoners of war.

"Um"

Ying Zheng could understand Xiao He's concern, nodded, and said, "I don't have to go to the Pingcheng coal mine mining site, but I will personally go to the Pingcheng coal craftsman workshop."

Regarding anthracite and bituminous coal, Ying Zheng knew that even if he didn't mention it, these Daqin craftsmen with craftsmanship would study it.

Here, he thought of another kind of thing, which is of great use to the Great Qin Empire, and it also exists in this era.

asphalt

In Ying Zheng's memory, he clearly remembers that asphalt was used as a cement-like binder to seal the Great Wall.

And asphalt is also an indispensable resource for the construction of gallops, cement, he has other uses, and cement roads are not suitable for cavalry rampage.

As soon as he thought of this, Ying Zheng felt that he should get the asphalt out. In this way, it would be good for the Qin Empire and not bad.

Over time, it will gradually drive away, and it will not take years to make the treasury of the Great Qin Empire empty.

Asphalt can be mainly divided into coal tar pitch, petroleum pitch and natural pitch.

In today's Daqin Empire, there is natural asphalt. Natural asphalt is petroleum asphalt that is formed by the long-term extrusion of oil by the earth's crust and gradually changes in contact with air and water. It exists in a natural form.

Generally, rock asphalt and lake asphalt exist in the territory of the Daqin Empire.

Crude oil penetrates the ground, where light components are evaporated, oxidized by oxygen in the air under sunlight, and polymerized to become bitumen.

It is mainly composed of colloids such as asphaltenes and resins, and a small amount of other mineral impurities such as metals and non-metals.

Most of this asphalt is naturally evaporated and oxidized, and generally does not contain any toxins.

The natural asphalt in the Daqin Empire existed in Wuerhe, the land of Bashu, and the north of Jianjiaguan in Shu County, and the area of ​​Longmen Mountain in Guangyuan in later generations.

Known as the No. 1 black mine in the Central Plains, the reserves are more than 10 million tons.

In addition to natural asphalt, there is also petroleum asphalt, but this is the product of petroleum processing, and today's Daqin Empire simply cannot do it.

Today, there are coal mines in Pingcheng, and the Daqin Empire can produce coal tar pitch. Ying Zheng remembers clearly that coal tar pitch is a by-product of coking.

However, the change of temperature has a great influence on coal tar pitch, which is easy to be brittle in winter and easy to soften in summer.

It's just that Ying Zheng was obsessed with coking pitch because it was a process that Li Kang called coking in his memory.

Coking refers to the process in which coking coal is heated to about 1000c under the condition of isolating air, and after high temperature dry distillation, coke, coke oven gas and other coking chemical products are produced by thermal decomposition and coking.

Metallurgical coke has high carbon content, high porosity and high strength. It is an important fuel and reducing agent for blast furnace ironmaking, and is also a proppant and bulking agent for the entire blast furnace column.

Coke oven gas, which is a by-product of coking, has a high calorific value and is an excellent gas fuel for open hearth furnaces and heating furnaces. It is an important energy component in iron and steel complexes.

The biggest reason why Ying Zheng was interested in coking pitch was because the items that appeared in the coking process were basically related to the breakthrough and maturity of iron smelting technology.

If the Qin Empire wanted to develop iron smelting technology and promote the transition from the Bronze Age to the Iron Age, coking was necessary.

However, at this time, the craftsmen of the Great Qin Empire did not realize this.

At this moment, Ying Zheng thought about it, and he didn't mind mentioning one or two. After all, this mention could make the iron smelting technology of the Daqin Empire advance by leaps and bounds.

Seeing the change in Ying Zheng's expression, Xiao He knew in his heart that this time Ying Zheng was only a matter of urgency. Thinking of this, Xiao He couldn't help but look at Li Si.

Now ~www.wuxiaspot.com~ Apart from the First Emperor, Li Si is the highest official present.

Aware of Xiao He's indecision, Li Si nodded and said, "Go ahead, His Majesty's will is Da Qin's will."

"promise."

Nodding in agreement, Xiao He left. Li Si was silent for a long time, then turned to Ying Zheng and said, "Your Majesty, why do you have to see these people with hundreds of craftsmen?"

Hearing this, Ying Zheng's eyes flashed with a gleam of light, and he knew in his heart that in this era, the status of Baigong people is very low, and they are not welcome.

Even if he raised the status of Daqin Shang Workshop, Shaofu, and even Daqin Baigong again and again, the effect was still not good.

Thinking of this, Ying Zheng sighed, "Prime Minister, do you know that the future of the Qin Empire is in their hands?"
