"Sanniang, look at it, this is vinegar cloth!"
Lu Qi went to Qian Niuwei's temporary camp and came back with a dark cloth.
Lu Qi's face turned slightly to one side, as if she was disgusted.
Gu Qingcheng was still a little puzzled. Although Lu Qi was not old, she had been with him for a year or two.
Moreover, her family is a servant of the Gu family. As long as she can remember, she has been taught rules by her elders.
In terms of "etiquette", it is no exaggeration to say that Lu Qi is no worse than some ordinary girls from official families!
What's wrong with this girl now?
There is such an exposed look of disgust?
Until Lu Qi came closer, a sour and smelly smell hit her face, and Gu Qingcheng could hardly control her emotions.
What does this smell like?
It goes straight to Tian Ling Gai, so sour and refreshing.
However, this vinegar cloth was brought to her by her own orders. Regardless of whether it smelled good or smelly, she had to take a closer look.
"Bring it here, let me see!"
"Sanniang, this smell--" It's really unpleasant.
Lu Qi is really afraid of intoxicating her Sanniang.
"It doesn't matter!" Gu Qingcheng is the most eager to learn. Since there is knowledge that she doesn't know, she must understand it.
Lu Qi sent the rag to Gu Qingcheng.
Tsk, that smell is getting more pungent.
Gu Qingcheng endured his disgust, moved closer, and took a closer look.
This is just a piece of cloth.
But it must have been soaked in some kind of seasoning and tainted with those flavors.
When Gu Qingcheng thought of this, he ignored the pungent smell and directly picked up the cloth with two fingers.
He brought it to his nose, twitched his nostrils, and sniffed carefully.
acid!
salty!
After all, Gu Qingcheng still had some scruples and did not taste it directly.
However, her six senses are sharp, and she can make a rough judgment through taste.
Lu Qi also explained on the side, "I asked the Qianniu Guard, and he said this is something commonly used in the army."
"Put salt and vinegar in the water, put the linen cloth in it and boil it."
"The linen cloth is stained with the smell of salt and vinegar. This is vinegar cloth."
"When it's time to march, cut the vinegar cloth into small pieces and boil it in a large pot, and the food will have a flavor."
Lu Yi said, resisting the urge to think "yue".
No way, when she was explaining, she couldn't help but imagine that scene in her mind.
Coupled with the pungent smell of vinegar cloth, her stomach couldn't help but churn.
"Salt is in such short supply?"
Gu Qingcheng was not an ordinary girl from an aristocratic family. She had been a queen and queen mother in charge of the government.
Therefore, from just a piece of vinegar cloth, she guessed that the crux of the problem was "salt".
Salt is indeed a good thing, and in this era, it is very rare.
Wait, how do you make salt now?
Gu Qingcheng's thinking began to diverge, and he tried to use his "common sense" to change the world.
"Executor, it's been more than a month, and the system has cooled down long ago."
Huoshui felt that Gu Qingcheng's heart was ready to move. He couldn't hold it back and jumped out again to remind: "Let's do a mission!"
"The more tasks you do, the more points you can earn."
"Have you forgotten your long-cherished wish? Don't you want to become a big, beautiful, human being as soon as possible?"….
Huoshui started to confuse as he spoke.
Gu Qingcheng: ...of course I have not forgotten my wish.
However, I won't act too eager, otherwise I will be in a passive position.
"No hurry! I still have things to do."
Gu Qingcheng did not continue to think about any new salt-making method.
Instead, he thought of ways to improve it based on the Western medicine skills he extracted from the previous mission.
Ate
During the meal, Gu Qingcheng took two maids and three or five tribesmen and walked around nearby.
The temporary resting place chosen this time was a mountainous area next to the official road.
There are mountains and forests and rivers.
Zheng Mo led the Qianniu Guards and shot some wild animals in the forest, which was considered as an added bonus for everyone.
Not to be outdone, the rangers caught some river fresh food in the river, and Gu Qingcheng ordered the cook to make fish soup, grilled fish, etc.
Everyone had a great time eating.
Gu Qingcheng took people for a walk in the mountains and forests.
Then, she discovered that there were some dark brown rock formations on the mountain near the river.
Gu Qingcheng's mind moved, and she called two steps: "Scrape off these rock layers and put them in a wooden barrel."
Although the Gu family members didn't understand why Gu Qingcheng did this, they would only obey the little master's orders.
Not long after, the two tribes followed the instructions of taking care of Qingcheng, took the rock formations, packed them in buckets, ground the large rocks into powder, and then set up a fire.
Boil the salt brine, filter it through fine linen cloth, and then filter it through layers of charcoal.
The water in the pot becomes clear.
Gu Qingcheng asked Bu Qu to find a flat stone slab. The midday sun made the stone slab very hot to the touch.
The salt water poured on the stone slabs, making a tingling sound.
The water slowly evaporates, leaving behind a shallow layer of white particles.
Lu Qi and Jiao Wei's eyes widened.
Even the two Bubu who had been helping with the work looked incredulous.
This, this is salt?
Seeing the reactions of several people, Gu Qingcheng couldn't help but curl her lips, "You can have a taste!"
After hearing this, Lu Qi quickly stretched out a finger, dipped it on the fine white particles, and then put it in her mouth.
"Salty!"
It's just like the fine sea salt you use at home.
But sea salt is so expensive, even slaves from wealthy families like them are not qualified to enjoy it.
My Sanniang did it so easily?
Lu Qi and other servants all showed surprised expressions.
However, they are all servants of the Gu family, and their lives, wealth, and glory are all closely related to their masters.
After all, it's just a salt-making method. Even if the master wants to rebel, they can only follow it.
Tell the truth?
Or a leak?
Haha, what are you thinking about?
The current law stipulates that if the master rebels and the slave exposes it, he will eventually die along with the master's family.
They are the owner's property, and whether they live or die is decided by the owner's family.
Gu Qingcheng didn't avoid them when making it, that's why.
After packing his things, Gu Qingcheng returned to the army with the finished product.
She showed the collected refined salt to Gu Heng.
Gu Heng raised his eyebrows, "Did you do it?"
He has never looked down upon his granddaughter because of her age.
His Aqing has no flaws except for her appearance. ….
His intelligence and character are more like the darling of God.
From ancient times to the present, there has been no shortage of geniuses. They are almost demonic in their wisdom, they are born with knowledge, and they have a photographic memory...many prodigies have left their mark on history.
Therefore, no matter how magical his granddaughter's performance was, Gu Heng would not doubt it, only feel happy and faintly regretful.
"Yeah! This is rock salt. It can be found anywhere near a river."
"Rock salt is poisonous!" Gu Heng traveled around the world in his early years and naturally had a lot of knowledge.
He had seen poor people who ate rock salt from the river and died of poisoning.
"You can use filtration to remove toxins from rock salt."
Gu Qingcheng said firmly.
Filtration, purification and other skills are the medical and chemical knowledge she learned during the Republic of China.
Because this has something to do with medicine, relevant knowledge points were also used when purifying penicillin.
Therefore, the system did not completely erase it.
Thinking of penicillin, Gu Qingcheng's thoughts moved again.
In fact, in ancient times, the ancestors of China also discovered penicillin.
I just didn’t continue my research.
"Stewed mustard greens!"
In the previous mission world, Gu Qingcheng was the only one who lived until 2015.
She also read online articles and learned a lot of "time travel trivia".
Other memories were erased.
But Gu Qingcheng had an impression of the knowledge related to medicine in the Republic of China era.
For example, this "Old Mustard Braised Sauce".
It is the earliest penicillin in China and has been mentioned by many online writers.
As you can tell from the name, this is originally a kind of pickle.
It is said that in a certain temple, the pickles were left for too long and a layer of mold developed.
By chance, the monk discovered that applying this moldy marinade to wounds could stop bleeding and reduce inflammation.
As a result, this temple has a "magic medicine" that will be given to the sick people around it.
With the connection with the temple, even if the disease is cured, people will associate the credit with the gods and Buddhas.
Then there was no in-depth study of mustard stew, and the opportunity to develop penicillin was missed.
...Uh, okay, these are Gu Qingcheng's own guesses and fabrications when he saw those online articles.
What is the truth of history, and how will future generations know it?
However, this story inspired Gu Qingcheng.
"Maybe I can try to refine it, maybe I can make penicillin?"
Chen mustard stew is a real item in history. Gu Qingcheng made it, so it shouldn't change history.
At most, at most, it was a few hundred years in advance and purified by the way!
Gu Qingcheng originally didn't want to get the anti-inflammatory medicine out so early.
But this time they were exiled to Lingnan.
There are many miasmas in Lingnan, as well as snakes, insects, rats, and ants. If you don't handle them properly, you will be injured, sick, or even poisoned.
Anti-inflammatory drugs are not a panacea, but they can also cure some diseases.
With more preparations, Gu Qingcheng can feel more at ease.
The large army continued to set off. When Gu Qingcheng was on the way, he would check whether there were any aged pickles along the way.
Zheng Mo: ...This little girl from the Gu family is really capable of twisting things.
Even the pickle jars of poor people are not spared.
The days on the road are monotonous and boring.
Even though Gu Qingcheng found a lot of things for himself, he was still a little bored.
"Executor, since you are bored, let's do a task."
Huoshui jumped out in time to increase his presence.
"That's fine!"
Gu Qingcheng looked at his little black hands, and then touched his dry and yellow hair.
Alas, it is so ugly, it really needs to improve its appearance.
"Then let's do a mission."
Gu Qingcheng lay in the bullock cart, turned away from Lu Qi and other slaves, closed the window, and was ready to "time travel".
"Okay! Executor, don't worry, I will randomly select an easy task for you."
In Huoshui's excitement, he started talking nonsense.
Gu Qingcheng's forehead twitched: They said they were randomly selected, how can they choose a good task?
Not long after, a new summary was delivered to Gu Qingcheng.
Gu Qingcheng clicked on it, and then fell into a state of contemplation——
Ah this?
Are you sure the system is not intentional? ! .
Salina
