Sword in the Qin [Comprehensive + Sword III]

Because Qin Feng and Lai Yao'er went to Leprosy Island, Ye Lange inevitably paid more attention to the affairs of Leprosy Island.After dinner, everyone was chatting, and Ye Lange had to talk about it.

"Senior Brother, Senior Brother, why can the spring water of the Black Water Spring burn, but not be extinguished by splashing it?" Xiaojiluo asked curiously.

"A lot of things can't be put out with water when they catch fire." Yang Suge explained, "For example, if the vegetable oil we cook in the pot burns, we can only cover it with the pot lid, but we can't use cold water to put out the fire. "

Xiaoqin couldn't understand, so she couldn't help asking: "Mother, why is this?"

"Because the density of oil is lower than that of water, the oil will float on the surface of the water. Putting out a fire with water not only fails to extinguish the fire, but also disperses the oil and spreads the fire." Shangguan Danfeng explained.

"What is density?" The children continued their efforts.

"I'll explain this to you later." Shangguan Danfeng said excitedly, "The black water spring that brother Ye mentioned is probably oil."

"Oil? I've never heard of it, but according to Lan Ge's description, it looks like stone fat." Yang Suge said.

"Mother, mother, what is Shizhi?"

Yang Suge smiled lightly, "It was recorded in Ban Gu's "Han Shu" in the Eastern Han Dynasty that 'Gao Nu has water that can burn'. Both the "Natural History" of the Western Jin Dynasty and the "Shui Jing Zhu" of Li Daoyuan of the Northern Wei Dynasty recorded this thing, saying It is "water has fat, like meat juice, take it into the container, it turns yellow and then black, like gelatin. It burns very brightly, and it is no different from paste. The paste and water are very good. Before I married Chuuxue, I traveled in the Northwest. I saw this thing in Jiuquan, and the locals called it Shiqi."

"In fact, you should be talking about the same thing. The name of oil is the name Shen Kuo took when he researched the object in the Northern Song Dynasty. In Shen Kuo's "Mengxi Bi Tan", it is recorded that there is oil in the territory of Yan and Yan...it looks like pure lacquer. It burns like hemp, but the smoke is very thick, and the stained curtain is very black... This thing will be popular in the world in the future, and it will be done from the beginning. It is covered with oil, and it grows endlessly in the ground, not like pine wood that sometimes runs out. 'It is recommended that the people use this material as fuel to reduce felling of trees. However, oil has a strong smoke and odor when it burns, and it is not available everywhere, so not many people use it."

Yang Suge and the others came from the Tang Dynasty and came to Daming not long ago, so it is naturally impossible to read all the books.The name of petroleum appeared in the Northern Song Dynasty, so Yang Suge naturally didn't know it.

"Black water spring, oil? Awow, Shen Kuo is worthy of being the most outstanding figure in the entire history of science in China. I used to only know that his "Mengxi Bi Tan" was amazing when I was studying. Forecasted the importance of oil!" Shangguan Danfeng jumped up in surprise, "Alas, what a pity, what a pity!"

"Sister Danfeng, what's the pity?" Seeing that Shangguan Danfeng was so excited, Xiao Pao couldn't help asking.

Shangguan Danfeng rushed over suddenly, grabbed Ye Lange by the collar, looked at Ye Lange like a hungry wolf and said, "Brother Ye, do you want to improve your sword-making skills in Hidden Sword Villa?" ?”

What a smart person Ye Lange is, Shangguan Danfeng asked this, and then thought of the boatman's words, he immediately understood: "You mean that the spring water of the Black Water Spring is only oil, and it can really make swords?"

"Most of the oil is buried deep underground. With the current technology, even if you know where there is oil, it is not easy to exploit. But the oil from this black water spring appears on the ground. You must not let this opportunity be missed. With oil as a raw material, you will definitely be able to Forge better steel, and you can make better swords."

"Besides being used as fuel, is there anything special about this oil?"

"You don't understand this. Oil is in my hometown, and it is an indispensable thing. Countries with oil are rich in oil. If they are weak and have oil mines, they will most likely be destroyed by bad luck. "

"This thing is so miraculous, it can also lead to a war of destroying the country?" Hua Manlou asked in surprise.

"It's just how to use this thing to make swords and improve the quality of swords?" Ye Lange asked.

For a swordsmith, it is definitely a very big temptation to improve the quality of the sword he forges.

"I didn't study chemical engineering before, so I can only give you advice, and you will have to study it yourself." Shangguan Danfeng said quickly, "Directly burning oil, in fact, not only pollutes the air with smoke, but is also very wasteful. Oil is because After being refined and reused, there will be a special factory in my hometown, which is what you call a workshop, responsible for refining oil.”

"Sister Danfeng, Feifei wants to know how oil makes a sword." Xiaojiluo said coquettishly.

"Petroleum can be refined to produce many petroleum products, such as gasoline and diesel oil. These things burn more powerfully than anything else. I know that another process of casting swords is very important, that is, refining ores to remove impurities."

"I understand! Using the oil you mentioned to refine gasoline and diesel as fuel can raise the temperature of the sword furnace to a higher temperature, thereby better refining ore and casting swords." Ye Lange said, "If this thing is really useful, Really useful."

"Since oil is something that can lead to a war to destroy the country, I'm afraid it's not so simple to use?" Hua Manlou asked.

"Feifei, Yuyu, do you remember that Sister Danfeng told you that Sister Danfeng's hometown uses airplanes, cars, and ships as means of transportation?"

Xiaojiluo and Xiaoqin nodded too hastily: "We remember! Sister Danfeng said that the plane in your hometown can fly very far with a single swish, and can run from the southernmost to the northernmost in one day, so everyone can eat Anything from anywhere."

"There is also a car, which can run faster than a horse without a horse. It can run three to four hundred miles in an hour." Xiaoqin stretched out her hand and gestured.

"Yes, but no matter cars, planes or ships, they all need gasoline and diesel as fuel. Just like horses eat grass, airplanes and cars also need gasoline and diesel to run." Shangguan Danfeng explained, "In addition to gasoline , diesel oil, and can also refine lubricating oil, asphalt and other chemical products. For example, lubricating oil is rubbed on the axle, the car can run better, and it is not easy to damage parts.”

"I know this, our family's organs and mechs sometimes need to be lubricated. Is this lubricating oil better than the oil we use?" Xiaopao said excitedly.

"Yes!"

"Then let's go get the spring water of the Black Water Spring and go back and have a look!"

"Sister Danfeng, what is that asphalt used for?" Xiaoqin asked curiously.

"In my sister's hometown, cement and asphalt are the two most important things for paving roads. With asphalt, the ground can be as neat as paving with bluestone slabs. In my sister's hometown, all roads are paved with cement and asphalt. It will be bumpy!"

"It's amazing!" The children opened their mouths in surprise.

"In short, petroleum is a very, very important and useful thing. In addition to these, it can also extract pharmaceutical ingredients and treat some diseases. Another example is the production of fertilizers, pesticides, and plastics. Fertilizers and pesticides can help Improve the fertility of the land and prevent the crops from being damaged by diseases and insect pests."

"This oil is so powerful!" Xiao Hualuo couldn't help but said, "Mother, let's also go to see the Black Water Spring. Sister Danfeng said that oil can also make medicine. Tell Dad, Dad must be very curious."

Yaoyue patted Xiao Hualuo's head helplessly, obviously she wanted to see this miraculous "medicine" but knew to use her father as a shield.

"If there is such a miraculous thing in the world, it would be worth seeing." Ye Lange nodded.

Although Yang Suge and Ximen Chuuxue had seen this thing occasionally before, they had never heard of it at that time.Now that Shangguan Danfeng said that the oil was so mysterious, it was inevitable that he would become curious.

Especially Ye Lange heard that this thing can help improve the quality of the sword, so how could he bear it.Immediately I wanted to go to the pier to find a boat and go to Heishuiquan to have a look.

The little ones naturally wanted to go too, Yang Suge and Yaoyue thought that if the oil in the Black Water Spring was really so miraculous, it would be good for the children to see it.They were only willing to accept the strict order not to allow the children to approach the leprosy village.

The children are now curious about the oil in the Black Water Spring, and they don't remember the Leprosy Village, so they naturally agreed.

Ye Lange said hello to Yang Suge and the others when he was gone, and wanted to go to the island overnight.However, it was not easy to find a boatman at night, and when they heard that they were going to Leprosy Island, those people were even more reluctant to pick them up.

Ye Lange simply paid the money, rented a boat, asked for directions, and rowed to the island by himself.

Curious about oil, the children got up early the next day.Seeing that Yang Suge was still resting, Shangguan Danfeng couldn't bear to disturb her.So he took the children to the street to buy melons and fruits and other things.

When they found a boat and were ready to set off, Shangguan Danfeng and several children had already bought two large carts of grain, fruits and vegetables.

"Mother, we bought a lot of melons and fruits in the morning, and they are still juicy, isn't it amazing?" Xiaoqin asked with her small face up.

"I heard from my senior brother that the people on the island are pitiful and lack medical care and food. Although we don't enter the leprosy village, Sister Danfeng said that we can give them food and help them." Xiao Jiluo explained .

"The babies are very capable and have done a good job." Yang Suge praised.

There were quite a few of them and they brought a lot of things, so they hired two small boats.But except for the boatman yesterday, no one else would go to Leprosy Island.So the other boat, like Ye Lange, chartered off the boat and rowed to Leprosy Island by himself.

Leprosy Island was much larger than they had expected. When they arrived on the island, the boatman helped them get their things off the boat, and immediately rowed away.

There was still a boat tied to the crude pier, which should have been left by Ye Lange last night.The other boat they rented was also tied together, and when they went in this way, they could row away by themselves.Instead of waiting another six or seven days for the boat to come to Leprosy Island before leaving.

After getting off the boat, the children and Shangguan Danfeng were going to deliver the food to the entrance of the leprosy village.

Although Hua Manlou couldn't see her, she walked briskly forward to help.Ximen Chuuxue saw his son carrying a basket that covered his small body, stepped forward and picked up two bags of rice and followed.

Although Xiao Jiluo is young, she is the strongest among the children, carrying a basket of melons and fruits very neatly.If it weren't for the lack of height, it might be easier to resist.Xiao Hualuo was the youngest and weakest, and she was very active in asking for help. Shangguan Danfeng helped her pick out the lightest basket.

Yang Suge's stomach was sticking out, even with martial arts protection, everyone would not let her help.Seeing that Xiao Hualuo was struggling to lift, he helped her lift a little from the side.Even Yaoyue casually carried two baskets of fruits and vegetables.

Shangguan Danfeng, who could barely wring out a towel before crossing, now has internal strength in her body, holding a bag of rice in each of her left and right hands.Following the team, seeing Ximen Chuuxue and Yaoyue walking in front carrying things, Shangguan Danfeng suddenly wanted to laugh, but didn't dare to.

The sword god and flower god who carried the rice, and Yaoyue who helped that thing, it feels like the gods and goddesses are disillusioned after stepping down from the altar!What about the promised idol burden, is it really good to let go of it?
