"The Marquis is here just right. My subordinates have found out that the green light in the laboratory yesterday!" The old pawn put down the cloth pocket in his hand and bowed his hand.

Chen Xu came mainly for this today, so he breathed a sigh of relief and asked, "What exactly is it?"

"It's this kind of ore!" The old alchemist opened his cloth pocket, and some fragments of ore were exposed inside, with blue-gray color.

Chen Xu picked it up and looked at it. He felt that the section had a slight luster, and there were fine yellow-green impurities mixed in it, like quartz stone. It didn't smell any after smelling it. Chen Xu looked through his pocket and found a small black stone to observe and said, "This piece seems to be flint?"

The old alchemist also took it over and looked at it for a few seconds and nodded, "The Marquis said it well, this is indeed a piece of flint!"

Chen Xu turned over his cloth pocket again and took a look. It was written on it with the words "Twenty Miles in the West of Jingshan, Nanjun". Literally, it can be seen that these ores should have been produced in the later areas of Jingzhou, Hubei, and the ores were mixed with flint. Maybe they were discovered by locals looking for flint.

"This kind of stone doesn't seem to shine, right?" Chen Xu picked up a piece of blue-gray ore again and watched it over and over again.

"Mr. Marquis, this ore does not shine. The reason for the light is that yesterday, after Yu Yuan distilled this ore the day before yesterday, some white substances remained in the decanter. In the middle of the night, it actually emitted a green light, so it scared the night-breaking fellow Taoist Ge!" The old alchemist quickly explained.

"Is the decanter still there? Take it to Benhou to take a look!"

"Here, wait!" The alchemist named Yu Yuan, who followed the old alchemist in, quickly ran to another workbench and quickly took a round glass bottle. Chen Xu took it and took a look. There was indeed a layer of milky white waxy substance inside, which was very rare, but you could feel a slight lubrication when touched with your hands.

"Marty, several of us saw it last night. When it was very dark, there would be a green light in the decanter, just like the ghost fire in the wilderness..." Yu Yuan said with a pale face as he waved.

"Bad ghost fire, I almost know what this thing is..." Chen Xu sniffed his fingers slightly, feeling a stinking garlic smell, so he quickly ordered the basin to wash his fingers clean, and then said, "This thing is called white phosphorus. When exposed to the air and in the dark, it will emit green phosphorescence. Fortunately, it is winter now, and it will definitely burn if it is summer. Also, this thing is highly toxic, don't get it into your mouth!"

"Marty is saying that Yu Yuan has brought out a poison from this ore?" A group of alchemists surrounded him with strange expressions and looked at the flask. Many of them shivered slightly. Obviously, if it weren't for Chen Xu's reminder, some people might really have plans to lick it.

"Don't be afraid. The great way is divided into yin and yang. Yin is the beginning of yang and yang is the end of yin. Yin and yang are the mutual generation of yin and yang is the Tao. The so-called poison does not need to be discussed in color change. Although this white phosphorus is obtained by accident and is highly toxic, if used well, it is also a benefit to the country and the people. It is just necessary to continue the experiment carefully!" Chen Xu waved his hand to comfort him for a few words, and then ordered to find a wooden barrel, put the flask in, and then cover the wooden barrel with a large piece of black cloth and said with a smile, "Everyone put his head in and you will know that this marquis is not wrong. In the dark environment, white phosphorus will emit green phosphorescence..."

"Marty, I'll take a look first!" Hu Kuan couldn't wait to put his head into the wooden barrel, and then yelled in surprise: "Marty, I really saw the green light!"

"Director Hu is coming out quickly, let me wait and take a look!" A group of alchemists couldn't help but get upset. After Hu Kuan came out, he stuck his butts and arched his head into the wooden barrel to watch, and he shouted in surprise and excitement.

After a group of people watched each other, Chen Xu asked someone to take out the flask and let a priest carefully scrape out the white phosphorus inside with a piece of bamboo. Finally, there was almost a tablespoon in a beaker.

"Everyone, this white phosphorus is highly toxic and particularly unstable. It will evaporate slowly when exposed to the air. If the temperature is slightly higher, it will burn. The flame is green, exactly the same as the ghost fire in the wilderness in the tombs scattered with corpses. Therefore, I just said that there are no ghost fires in the world. In fact, the ghost fire in folk legends is also called phosphorus fire, not ghosts..."

"Everyone will spread apart. I lit it to show you the essence of ghost fire and give me the matches..." Chen Xu ordered a alchemist to find a match, and after struck several, he finally ignited it, and then threw the matches into the beaker.

"Boom~~"

Just as the burning match fell into the beaker, a blue-green flame soared into the air from the beaker.

"Wow~~" A group of alchemists retreated in an instant and a large area emerged. Under the reflection of the green phosphorus fire, not only everyone's face was reflected in green, but the entire laboratory was extremely green and gloomy.

"So cold!" A timid alchemist waved slightly.

"Shuh, it's a cold thing, the Marquis said, this is the Phosphorus fire..."

"Then why are you trembling..."

"Hehe... I didn't... I didn't shake... Damn, why is your face green..."

"Your is not green yet... green, even your hat is green..."

Although Chen Xu explained that this is white phosphorus and not ghost fire, it was useless, because no one had ever touched this green flame that made people feel chilled. It was so close that it was burning in front of everyone. In this era when legends of gods and ghosts were rampant, the first reaction was to pull it to ghosts.

A spoonful of white phosphorus was quickly burned out. Looking at a group of alchemists who were careless but were frightened to the point of being white like quails, Chen Xu said amused and crying: "Okay, okay, don't be afraid. This phosphorus is not only found in ores, but also in animals and human bodies, especially in bones. After humans and animals die, the bones rot, and these phosphorus will be released slowly. In summer, the temperature will be higher and burn by themselves. Therefore, someone saw ghost fire in the wilderness. If you don't believe it, you will know when you go to the deserted tomb with many people in summer..."

"This white phosphorus was discovered by Yu Yuan and Ge Qing. This Hou decided to reward each of them with two thousand coins. In addition, the white phosphorus refining test cannot be carried out in the chemical laboratory after the refining test. It is easy to burn or even explode, which is too dangerous!"

Yu Yuan and Ge Qing were immediately flushed with excitement, and the rest of the laboratory also showed envious expressions of congratulations to the two winning guys.

"Mr. Marquis, you just said that phosphorus is highly toxic, but you don't know how to use it, or what it can be used for?" Yu Yuan couldn't help asking after a burst of excitement.

"Phosphate is a very strange element. There can be many different states in nature. White phosphorus is toxic and easy to burn and explode, but after treatment, it will turn into red phosphorus. Not only is the state stable but it has no toxicity at all..."

Chen Xu picked up a box of matches just now and said, "Everyone knows matches are better than flint, but in fact they are not very convenient to use. Sometimes you have to scratch a lot of roots to ignite. The main reason is that the combustion aid inside is unstable and not easy to burn. It is easy to use white phosphorus, but the nature of white phosphorus is unstable and highly toxic, which can easily cause matches to spontaneously ignite and cause accidents. Therefore, if we convert white phosphorus into red phosphorus and then use red phosphorus to make gunpowder, the matches made will be very easy to use and safe!"

"Mr. I asked the Academy of Sciences to develop matches, but it has not been successful, so I did not have a large-scale promotion and use. Now I have discovered white phosphorus. If the white phosphorus can be converted into red phosphorus, then I can organize a match factory to promote matches on a large scale, and flint can be completely abandoned... Yu Yuan, I will hand over this task to you. If you can find a way to convert white phosphorus into red phosphorus, I will apply for an invention patent for you and give you shares in the match factory to ensure that you will never spend the money you earn in the future!" Chen Xu said to the young Taoist priest who is about thirty years old.

"Don't worry, my subordinates will definitely complete the task!" Yu Yuan waved slightly excitedly.

"Today this is an unexpected gain. At the same time, this incident also tells you that you should not ignore any details in chemical experiments. Perhaps a small abnormality is an extremely important discovery and innovation. Don't let go of any doubts in the future. Okay, the Japanese Marquis are here to see the soap. You have all dispersed. Do whatever you should do!" After Chen Xu waved his hand and drove Hu Kuan away a group of irrelevant people, there were only more than a dozen alchemists left in the laboratory.

"Mr. Marquis, this is the soap you made yesterday!" A alchemist was so proud that he brought yesterday's beaker over and placed it in front of Chen Xu.

Chen Xu gently pressed it with his hand and found that it was very soft, basically unlike soap and soap, it belongs to a paste.

Could it be because it has not been released for long enough?

Chen Xu dug out some with his hands and tried it. He found that it was no different from soap. It was indeed very clean and the taste was no different from soap in later generations. It seemed that there was a faint smell of alkali.

The alkaline smell is probably the residue of alkaline water left in the saponification reaction. Just try a few more times to adjust the reaction ratio of alkaline water and oil. However, to make soap, you need to add some floral essential oil.
