Although he loved astronomy and geography, he knew a little bit about alchemy. When he was tired of studying armpit spheres, he came to Xi Changnian to see jokes. Unexpectedly, he got himself in as he watched.

It seems quite interesting to make this ammunition.

He felt that he might have accidentally jumped into the pit that Gu Qingyi dug again, but he had no evidence.

"If you adjust the elixir recipe, if you want to increase the power, you have to increase the ratio of sulfur and saltpeter." Zheng Huan asked tentatively.

Gu Qingyi must have something in her stomach that hasn't come out.

Gu Qingyi was also worried, she knew a little, but it would definitely not work if she could tell the modern formula over thousands of years.

One step ahead is a genius.

Three steps ahead of time are crazy.

If you are ten steps ahead of time, Zheng Huan must have suspected that there is something wrong with her brain. What if you become interested in staring at her for research?

Gu Qingyi has really put a lot of effort into ensuring that he is a genius rather than a lunatic, nor a guy with an abnormal mind.

She remembered that there was a "Sulphur Fire Conquering Method" which was also considered the earliest version of gunpowder. It was slowly extracted from the alchemy techniques of ancient alchemists. This was not very advanced and could be used.

The three-yuan system gunpowder appeared during the Sui Dynasty, and the black gunpowder appeared during the Tang Dynasty.

Gu Qingyi felt that he could guide him slowly from the three-element system, so he said: "It is also a way to simplify everything. There are too many things that need to be added to the elixir. We are just for the power of the explosion. In fact, there are no necessary things that can be removed. What do you think?"

It’s not for immortality, it’s for killing enemies on the battlefield.

This statement is nothing wrong. In order to live forever, the medicinal materials added can be completely abandoned, and the rest can be guided slowly.

It’s like sulfur. People mine it very early and often encounter sulfur in their daily life and production.

The hot springs release the smell of sulfur. When smelting metals, the sulfur dioxide emitted is pungent and unpleasant. People with a little experience and knowledge will know.

Besides, the earliest nitride that the ancients mastered was the soil nitride under the corners of the walls and the roots of the house. Saltpet is a very lively chemical property and can react with many substances. Its color is not much different from other salts, and it is easy to get confused during use, so it is prone to various accidents.

Mastering the method of identifying saltpeter can also easily improve the success rate of gunpowder.

When she was studying chemistry when she was in school, she liked to do various experiments and watched various chemical elements change differently with different substances. This is a very addictive hobby.

For a while, she liked to hear a senior talk about these things, and she was also very interested in doing experiments by herself.

I remember that my senior once mentioned to her that the earliest method of identifying saltpeter should be Tao Hongjing’s “Cooked with fire, purple and blue smoke rises, and clouds are true saltpeter”, which is similar to the method of identifying potassium salt using flame reaction in modern times.

Saltpeter and sulfur were once used as important medicinal materials. In the "Shennong Bencao Jing" of the Han Dynasty, saltpeter was listed as the sixth highest-grade and sulfur was listed as the third highest-grade medicine. Therefore, it makes sense that alchemists are obsessed with adding them to pills.

Everyone knows why it is not difficult to guide the seats inadvertently for many years, but there is a Zheng Huan who is more sophisticated than a monkey, and Gu Qingyi is a little bald.

She could only pretend to raise a little doubt and let them diverge themselves. She really had no choice.

Just like this, Xi Changnian's eyes lit up, and she ran to another intact elixir house with barefoot with her hair disheveled.

Gu Qingyi:...

At least pay attention to the image.

Forget it, this is like the experimental madmen in later generations. They have always focused on what they like, and their appearance is full of clouds.

As soon as Xi Changnian left, Zheng Huan also stood up with Gu Qingyi. After squatting for a long time, his feet were a little numb. He stomped his feet twice without caring about his image, and then said: "Fire method alchemy is dangerous. If the alchemy recipe is streamlined, the danger is even greater."

Gu Qingyi:...

She knew that Zheng Huan was not easy to fool!

"Master Xi is good at alchemy, but Brother Zheng is cautious. It is because Brother Zheng is here that I dare to make this suggestion."

Zheng Huan's face twitched, and he looked at Gu Qingyi with a little smile, "I don't have time, I still have to study my armillary sphere."

Gu Qingyi's smile froze, "Oh, I seem to have some new insights into the armpit sphere. When Brother Zheng finishes his work here, let's discuss it carefully."

Zheng Huan nodded with satisfaction and strode with his hands behind his back.

Xi Changnian's fool, without him staring at him, might be able to get himself into the alchemy furnace to practice human flesh and medicine in a few days.

Gu Qingyi looked at Zheng Huan's back and felt disappointed. She felt that she needed to make up for it. She used her brain too much and didn't want to die suddenly. She still wanted to live well.

Hiding his hands in his sleeve, Gu Qingyi released the little jade tree, pulled out two leaves and stuffed them into his mouth.

Xiao Yushu:...

The whole branch shaking, the leaves it had just grown!

Finally, I won’t get bald!

Is this what people do?

There was a very subtle telepathy between Gu Qingyi and Xiaoyushu. He could feel his anger now, and he couldn't help but sigh, "Xiaoyu, baldness is also bald once, and twice, and I'm used to it when I'm bald. Besides, if I'm exhausted, you won't have a chance to bald, right? The most important thing in being a human is to be happy, and the most important thing in being a tree is to be tactful, do you think so?"

Xiao Yushu was about to be angry and ignored Gu Qingyi at all, retracted his palm and kept motionless in protest.

Gu Qingyi was worried, look at how sad she was in this life.

Uncle Huang is just a time bomb. Xiao Yushu rushed up when he saw him. What does it have to do with her?

When it went crazy by itself, she was not ashamed to cure it.

In addition to the emperor's uncle, there is now a Xi Changnian who has become crazy by refining alchemy, and there is also a Zheng Huan who is more refined than a monkey. She is too tired.

Only when she lives well can Xiao Yushu be able to do it.

At a young age, he looked vicissitudes of life.

Gu Qingyi felt that there was no more time traveler than her.

In order to comfort herself, she decided to go back and have a good sleep.

Gu Qingyi slept until dark. After getting up, she remembered that she would invite Li Chaying to dinner at night, so she quickly got up and washed up.

Mianchun and others came in with copper basins and other items. Zhan Xia smiled and said, "The girl from the Li family said she would go outside and go around and she would have to wait a while before she could come back. Girls don't have to worry."

Gu Qingyi breathed a sigh of relief, "Cha Ying went with her sister?"

"Yes, the fifth lady leads the way, but the third lady doesn't let me follow you."

Gu Qingyi was dressing up in front of the mirror. At this time, the mirror made of brass was not very clear. It was necessary for craftsmen to polish it carefully to see a little.

When she saw the mirror, she was ready to make the mercury mirror come out, but she had to hold it back.

After packing up, I saw the menu and the weather was hot, so I placed the banquet in the octagonal pavilion in the back garden. Because in the octagonal pavilion, Gu Qingyi made a simple mechanical shake fan.

This is a simple mechanical principle. When someone steps on the pedal, four fans will be moved by themselves when they are placed in the octagonal pavilion.

This thing is not very difficult. It can be liberated that the little girls have to keep working hard to fan with their hands. As long as they know a little mechanical principle, they can do it.

However, when seeing this method of fanning, the Li Chaying sisters were still very interested.

Especially not only because this method of fanning is beautiful, but also has a strong wind. If it is a banquet, it will be very sequel.

Li Chaying couldn't sit still at all. Looking at the fan that was constantly rotating above her head, she said to Gu Qingyi: "How do you have such a brain? You can do it."

Gu Qingyi smiled, "I just said it casually, it was made by craftsmen. If you like it, bring two pieces back when you leave, it will not be difficult to make."

Li Chaying agreed in one go, and Li Mingying couldn't even stop him.

She saw Gu Qingyi getting along with her cousin very casually. She asked for something and answered it casually. She asked for something and asked for something casually.

No wonder Cha Ying talked about Gu Qingyi's affairs in the clan. Suddenly, she envied their friendship.

At least, she doesn't have such friendship.

Cha Ying wanted it so well, but Li Mingying couldn't say anything without hesitation, looking at Gu Qingyi and smiling, "Will it delay your business? I saw that the fort was very busy, so where would I have time to do this?"

Gu Qingyi waved his hand, "It's okay. I made a few more items earlier. It was used for my brother and the others. Now it's not that people are not in Yuzhou, so I will take them back and use them first. Before my brother and the others come back, I will definitely make them again."

Gu Qingyi was so happy that Li Mingying did not refuse, but instead said with a smile: "My sister Qingyi was so happy, I took it with a thick face. This thing is really good, and it's great to enjoy the cool summer."

The three of them talked and laughed, and soon Zhiqiu brought someone to serve the dishes. The maid brought dishes of color, fragrance and flavor to the table like a maid.

Li Mingying looked at the dishes on the tables in front of her in surprise. They looked beautiful and smelled strong. She had never seen anyone cook like this.

However, Li Chaying had eaten the skills of the chef in Gu Qingyi's mansion and said to her cousin with a smile: "Sister, try it quickly, the food in Qingqing Mansion is very delicious."

In summer, there is no shortage of all kinds of river food. Gu Qingyi asked the chef to make a casserole of crucian carp. The casserole is made of flat soil and is very useful. It is a great choice to cook and stew soup.

Another dish is steamed grass carp in wild mountain pepper. The grass carp has been caught and kept in a water jar. After spitting out the mud and sand in the stomach, it will be put on the pot. Then marinated with wild ginger to remove the fishy smell. The steamed meat is fresh and tender and smooth.

Not only is the food full of flavor and flavor, but the bowls and plates used are exquisite. Li Mingying has seen many good things. Aristocratic girls like them have cultivated their aesthetic knowledge since they were young, but she still thinks that this meal is indeed unforgettable.

Because it was the first time to entertain Li Mingying, Gu Qingyi couldn't just serve fried foods, including a dish of fish soup, a dish of steamed fish, and a few cold dishes for summer. Finally, drink a bowl of Poria Lotus Seed Poria porridge, add a little sugar, put it in cold water before serving. When it's time to enter, the cool air is slightly sweet, suppressing the dry air of summer.

After the evening meal, Li Mingying took her sister to say goodbye. After a busy day, the host should have a good rest. Naturally, he should be aware of the guests.

On the way back to the hospital, Li Chaying never had a smile on her face.

When he returned indoors, Li Mingying looked at her cousin and asked, "So happy?"

"Of course I'm happy, sister, I'm right, Qingyi is really a good person to get along with."

Li Mingying nodded. What is rare is Gu Qingyi's sincerity in hospitality with guests. Even people like her feel very comfortable and comfortable.

Lee Mingying doesn't think it's a mistake to be picky, but it's really a pleasant thing to meet such a person that makes you feel appropriate and thoughtful everywhere.

Being friends is indeed a good candidate.

Li Mingying remembered what the patriarch said and already recognized this marriage very much.
