I make a popular science video and all the emperors learn from it!

[Popular science on the earth, the ten most precious natural resources!]

[Seventh place: oil.] 】

Petroleum is a viscous, dark brown liquid known as the "blood of industry.] 】

[In some areas of the upper crust, there are oil reserves. 】

[The main ingredient is a mixture of various alkanes, naphthenes, and aromatic hydrocarbons. 】

【The color of the oil:】

[The color of petroleum is very rich, including deep red, golden yellow, dark green, black, maroon, and transparent. 】

[The color of petroleum is determined by the content of gum and asphaltene contained in it, and the higher it contains, the darker the color. 】

【......】

[Early use:]

[As early as the 10th century B.C., ancient civilizations such as ancient Egypt, ancient Babylon and the Three Kingdoms of Afghanistan have collected natural asphalt for construction, antiseptic, bonding, decoration, and making ~ medicine. 】

[The ancient Egyptians were even able to estimate the amount of oil seeping out of the seedlings.] 】

[In cuneiform, there is also an account of the collection of natural oil on the shores of the Dead Sea.] 】

[In the 5th century AD, near Susa, the capital of the Persian Empire, there were oil wells dug by human hand. 】

[The first use of oil for warfare was also in the Middle East.] 】

[In the book "Oil, Money, and Power", it is stated that Homer's famous work "The Iliad" recounts that "the Trojans kept throwing fire on the clipper, and the ship suddenly rose into flames that could not be extinguished."] 】

[In the 7th century AD, the Byzantines mixed oil and lime, lit it, and shot it from a distance with bows and arrows, or threw it with their hands, to attack the enemy's ships. 】

[The Baku region of Azerbaijan is rich in oil and gas seedlings. 】

[The inhabitants of this area have long collected oil from the oil seedlings for fuel, and it is also used to cure the skin diseases of camels. 】

【...】

China is also one of the first countries in the world to discover and utilize oil. 】

[The Book of Han written by Ban Gu (32-92 AD) of the Eastern Han Dynasty records that "Gao Nu has water that can be burned". 】

[Gaonu is near Shaanxi Xiyan, and Weishui is a tributary of the Yan River. 】

["There is fertilizer on the water, which can be taken and used" ("Water Jing Note" by Li Daoyuan of the Northern Wei Dynasty). 】

[The "fertilizer" here refers to oil. 】

[Around 863 A.D., Duan Chengwu's "Youyang Miscellaneous Tales" of the Tang Dynasty recorded that "the stone grease water in Gaonu County is greasy and floating on the water, such as lacquer, and it is extremely bright with burning lamps". 】

[The Western Jin Dynasty's "Naturalist Chronicles" (written in 267) and "Notes on the Book of Water" all record that "the spring water comes out of Nanshan in Yanshou County, Gansu Spring," the water is fat, such as gravy, and in the holding vessel, it is yellow at the beginning and then black, such as the condensation paste, burning extremely bright, no different from the paste, the paste and the water jar are very good, and the other side is called the stone paint." 】

[Shen Kuo of the Song Dynasty read the sentence "Gaonu County has water and is combustible" in the book, and thought it was very strange, how could "water" burn?]

[He decided to go on a field trip.] 】

[During the investigation, Shen Kuo found a brown liquid, which the locals called "stone paint" and "stone grease", and used it to cook on fire, light lamps and keep warm. 】

[Shen Kuo figured out the properties and uses of this liquid, and gave it a new name, called petroleum. 】

[It is pointed out that "oil is abundant and born in the earth is infinite."] 】

[And mobilize the people to promote the use of trees, so as to reduce the felling of trees.] 】

[Shen Kuo wrote in his book "Mengxi Writings": "There is oil in the territory of Yan and Yan...... It is quite like pure lacquer, burning like hemp, but the smoke is very thick, and the curtain is very dark...... This thing will be great in the world, and it will be done from the rest. Cover oil at most, and be born in the earth endlessly, not as pine as sometimes exhausted. "】

[He tried to make ink from oil and soot produced by combustion, "black light is like lacquer, and pine ink is not as good.] 】

[Shen Kuo discovered oil and predicted that "this thing will be popular in the world in the future", which is very rare. 】

[In the Yuan Dynasty, the "Yuan Yi Tongzhi" recorded that "there is a well of oil chiseled in the south of Yinghe in Yanchang County, picking up catties, its oil is combustible, and treating six animal scabies, and the year is one hundred and one catty." There is a well in Yongping Village, eighty miles northwest of Yanchuan County, with an annual allowance of 400 catties, and the Yanfeng Reservoir of the road. 】

[He also said, "Oil, in the stone well of Yaoqu Village, West Twenty Miles, Yijun County, draws water and takes it, although the smell is smelly, it can cure camels, horses, sheep and cattle scabies."] "】

[It shows that about 800 years ago, northern Shaanxi has officially dug wells by hand for oil production. 】

[Its use has been expanded to treat skin diseases in livestock, and it is purchased and stored by the government.] 】

【......】

Qin Dynasty.

Ying Zheng looked at the light curtain, frowning and pondering.

It's really weird.

He had never heard of a water that could be burned, and it was buried in the ground. (If you read a violent novel, go to Feilu Novel Network!)

Of course, what he cares about more is oil, which can be called "the blood of industry"!

In the previous popular science, he learned that Westerners relied on the industrial revolution to catch up with and surpass China in just a few hundred years!

It can be called blood, you can imagine its importance to the industry!

Ying Zheng watched it again from the beginning.

Found a keyword: "Gao Nu has this kind of thing!"

He instantly became excited, and immediately ordered the soldiers to go and check.

Han dynasty.

Liu Che looked excited.

"Oil! There is not only a lot of this thing, but it also has so many effects!"

Just from the above popular science, you can see the role of oil.

One is that it can be burned.

Since it can be burned, it can be used in military warfare, which is much more cost-effective than fire oil!

In addition, it can also allow people to cook and keep warm. []

If it is really the same as the light curtain, this thing is almost inexhaustible, then it is even more profitable!

Second, it can treat skin diseases of livestock.

This is also very practical.

In particular, the treatment of cattle, sheep and horses was extremely important to the Han Dynasty.

Third, it can make ink.

This effect is also what the Han Dynasty currently needs.

Liu Che stood up excitedly and shouted: "Wei Qing listens to the order, I order you to go and explore Gaonu County immediately, be sure to find the source of oil, and find out how much it has!"

"Yes! The minister will be fortunate not to be dishonored!" Wei Qing waved his hand and strode out of the imperial city.

Tang dynasty.

Li Shimin feels like he has been in the dark!

There are things recorded in the Eastern Han Dynasty.

He hadn't heard of it.

Why didn't even the minister and the people around him mention it?

His face was a little ugly, and he let such a precious thing be put aside!?

After Cheng Yanjin observed the words, he realized something, he took three steps and made two steps, and stepped forward to take the initiative to ask for instructions: "Your Majesty, the minister is willing to explore the oil." "

"Where there is, how many, the minister will investigate clearly. "

Li Shimin tilted his head slightly, and his anger subsided a lot.

"It's bothering Lu Guogong. "。
