Chapter 88 Blood and Light

Kerosene, gasoline, and diesel oil are all refined from petroleum, and the first time that petroleum emerged in the history of our country was the Song Dynasty.One of the most famous scientists in history, Shen Kuo, a native of Qiantang, Hangzhou in the Song Dynasty, mentioned in "Mengxi Bi Tan" that oil flows out of the surface from the sand near the water, along with the spring water, sticky like paint, and burns like hemp when burned , can blacken things that touch it.At that time, oil was not called oil, but fat water.Before the discovery of petroleum, oils, both edible and military, were extracted from plants or animals. Vegetable oils are not flammable, and animal oils are mostly flammable except lard. Therefore, oil is called fat water. In the meaning of class nicknames.

At the end of the Eastern Han Dynasty, most of the military fuel was replaced by tallow and sheep oil, also known as ointment. The torches used for lighting were filled with sheep ointment on the wrapped cloth head, and the fire lasted for a long time.According to Tian Zheng and Zhang Tan's investigation, the cause of the fire in Siyi was that the gangsters piled cloth balls smeared with goat paste, sawdust and other combustible materials on the east wall, and then used the goat paste as a guide to spread the fire along the east wall. The walls spread.Knowing the cause of the fire is not enough evidence. Goat ointment is considered a daily consumable in this era, and there are many vendors in the ointment business, so it is impossible to know who did it.

In the afternoon of early autumn, the weather was bright and the cool breeze was blowing. It was a good day for traveling. The three sons of Beidi County took six family members out of the city with their money. demeanor.

"Brother Li, I've been suffocated these days. My barabara finger hasn't left the house for more than half a month. You said that the Second Highness was assassinated. What does it have to do with me? I agree with my father." I've said it no less than ten times, but he won't let me take a step out of the house." Fu Yang complained as he walked, and the eldest son who calls the wind and rain is not expected to be an otaku, but from his words, it can be seen that the Fu family did it. Fu Yang didn't know about those activities, probably because Fu Qing felt that the youngest son was too young, and was afraid that his leak would cause death.

Li Ying glanced at Fu Yang meaningfully, expressing his deep sympathy: "Isn't it? I've been stuck at home all day, and I've faded away. I poked a hole in my stone roller."

Tang Jun laughed softly: "Brother Li, why are you poking the stone roller when you have nothing to do? Are you afraid of flashing your waist?"

Fu Yang laughed loudly when he heard the words: "Hahaha, brother Li has a very strong waist, let alone a stone roller, even that iron pomegranate in the city can poke holes!"

Being teased by the two, Li Ying didn't get angry, she just rolled his eyes at the two of them: "Go, go, there's nothing wrong with you at home, and when you come out, you still suffer from the anger of the two of you. If you laugh again, I'll go back."

"Don't, don't, Brother Li, don't spoil the fun, why don't we stop laughing?" Fu Yang hurriedly pulled Li Ying back.In the entire Beidi County, only Li Ying and Fu Yang can play together because they are like-minded. Although the two of them do not like each other from the bottom of their hearts, they are still satisfactory playmates on the surface.The purpose of this trip is to go to a small village ten miles away from Beidi County. I heard that the hunters there have caught a black-faced man weighing nearly [-] catties, which is a wild boar.If Fu Yang was allowed to go by himself, Fu Yang really didn't have that leisurely mind.
