Li Xiang has a bolder idea, this idea has been hovering in his heart for a long time, but he has never dared to think about it seriously, this is the refining of oil. Pen ~ fun ~ Ge www.biquge.info the Song Dynasty had a simple method of oil exploitation, and was able to achieve a certain depth of drilling, so Li Xiang was ready to apply the blood of the oil industry hundreds of years earlier than the original history. In fact, it is not difficult to produce low-grade gasoline and diesel.

Gasoline and diesel can be obtained by simply distilling crude oil at a certain temperature range, and some later local oil refining methods are used in this distillation method.

The specific method is: first weld a simple steel tank with a steel plate, then seal the top of the tank, and install a collection tube on the top, then heat the crude oil, and control the temperature within a certain range, at this time, some light oil will be steamed first, gaseous gasoline through the collection tube, and then through a simple heat exchanger for cooling, it becomes liquid gasoline, if the distillation temperature is increased, diesel can be produced. However, the quality and stability of the gasoline and diesel refined by this local method are extremely poor, and the refined gasoline will be black after being placed for a period of time, and the gasoline engine will cause carbon deposits in the cylinder after use, and even damage the engine.

However, diesel is different because the motive of machinery such as tractors is simple to maintain and is not as delicate as the motive of gasoline, so it can be used to make diesel oil by the local method. As for the lubricating oil, it is a narrow distillate product, and the refining of lubricating oil has to go through multiple processes such as heavy oil cracking, catalyst reaction, distillation, and additive blending, which is obviously not a goal that can be achieved in the near future.

The next day, it was the day when Li Xiang made an appointment with his second daughter to go out. Li Xiang slept lazily, and just finished washing up and went out of the room, only to see that Lu Shiya and Yuru had already packed up, and then looked at the items prepared by the two, Li Xiang was really taken aback. At this time, a large number of items have been placed in the yard, in addition to a few large bags of fruits, there are also ** small blue seeds, which are filled with rice, steamed cakes, sugar cakes, mushrooms, mushrooms, bamboo shoots, fungus, daylily, stone cauliflower, seaweed, cranberry, taro, raph, yam, yellow essence, bacon, cured meat, green vegetables and other more than a dozen kinds of food, as well as several large boxes of various snacks, plus a few buckets of water, as if fleeing. What made Li Xiang even more depressed was that the two girls each brought a full set of toiletries and makeup utensils. Although the cosmetics in ancient times were extremely simple, they were not small in size, and they took up two small wooden boxes.

Facing the large pile of things in front of him, Li Xiang opened his mouth, and didn't know what to say for a while, and after a long time, he stammered: "This ...... I ..... we just go outside for a day, not moving......"

Lu Shiya smiled: "Of course it's not moving, if you want to move, how can three carriages be." Li Xiangqi said: "Three carriages? ”

Yuru said with a smile on the side: "Originally, there were only two cars, but Sister Shi will bring another one later, a total of three cars." No, there are five chairs. Li Xiang was even more surprised, and then followed Yuru's gesture to look, and sure enough, there were five small chairs standing next to them, although these five chairs were small, they would definitely occupy a huge space if they were to be installed on the carriage.

Li Xiang was first surprised by the two girls' preparations, and then suddenly heard that Shi Bingxue was also going forward, and he was even more confused, but he faintly felt very relieved, as if the things that had been hanging in his heart for the past few days had finally been settled.

I heard Lu Shiya say: "The day before yesterday, the two of us saw that you always couldn't think of a three-person poker game, and we weren't going to play this kind of card, but then thanks to Yuru's reminder, I thought of Sister Bingxue, so as soon as we talked about it yesterday, she naturally agreed to go together." ”

Li Xiang was stunned when he heard this, thinking to himself, how could Yuru suddenly propose to go with Bing Xue? Could it be that I was too careless that day, and I was actually seen by this little girl? Thinking of this, Li Xiang turned his head to look at Yuru, only to see that Yuru was looking at him with a smile, and when he saw that he was looking at her, he suddenly turned his head again, and was busy beckoning those little maids to go.

Li Xiang couldn't help but feel weak for a while, and when she looked at Lu Shiya again, she saw that she was looking at herself with a smile at this time, and she didn't see anything unusual at all. Li Xiang couldn't help but think about it again, but no matter how hard he racked his brains, he couldn't find a reasonable explanation. Xindao: The last time I went to see the steam engine, Shiya also took the initiative to ask Bingxue to go with her, and now she has made an appointment with Bingxue again, isn't Shiya jealous? Yes! Shiya must think that I will only like her alone, and naturally I don't care about asking other women to go with me, I am in such a ghostly mood, how can I be worthy of Shiya's true feelings?

He suddenly slammed again, and said in his heart: Li Xiang, Li Xiang, you are also a big man, and you are so speculating about the little girl's mind, this heart is too small, and it can't even match an ancient woman, can you only face those stupid people all day long?

Thinking of this, Li Xiang was arrogant, and laughed and said, "Okay! Go together, go together! It's just one of the three, and it's not easy to find a leg! Li Xiang's shout startled Lu Shiya and Yuru, and the two hurriedly turned around when they heard the sound, but saw Li Xiang with his hands on his chest, looking heroic.

Yu Ruqi said: "What three are missing one?" Also, what are the legs? ”

Lu Shiya followed: "Yes, what is a leg?" Why does it sound so indecent......"

Li Xiang was stunned when he heard this, and suddenly realized that he was a little out of shape, thinking that he was too carried away just now, and he didn't choose to speak, they naturally couldn't understand these hemp field terms, and laughed and said, "This...... There is a game that requires four people to play, and if there are exactly three people, it is called three missing one, and the other person is the ...... What's up. ”

Shi Bingxue had also come at this time, and Li Xiang saw that she really brought a carriage, and Lingzhu followed her, and also brought a lot of food. Li Xiang was about to come forward to say hello, but saw that Lu Shiya and Yuru had already greeted him, and the four girls laughed again, and actually hung Li Xiang in place. Shi Bingxue turned around and smiled apologetically at Li Xiang, and then followed Lu Shiya and Yuru to Zhang Luo. Li Xiang was alone on the sidelines, feeling a lot of emotion, thinking that where the Song Dynasty was patriarchal, it was obviously a woman's world.

When Li Xiang first arrived in the Great Song Dynasty, he also wondered if the Song Dynasty was really like what was recorded in the history books, if a woman was touched by a man, or even just touched her hand, she could only follow that man for the rest of her life. Later, he is not like this now, on Lin'an Street, you can often see women shopping on the street alone, not all of them are married women, and some of them are not married to the yellow flower girl, and some shops are extremely supportive, to always prevent others from touching themselves is obviously impossible, although it is not really touched through the clothes, but at least it is much better than what is recorded in the history books.
