Yipin County Magistrate: Start with invincibility

Chapter 117
The next day, Ninghai County.

Qin Feng sat in the room frowning.

The matter of locust plague can be solved as long as there is money. Qin Feng has already arranged it, and only waits for the funds from Su Jin to be in place.

And this day's work, he is mainly engaged in chemistry.

The "fairy water" he sells in Sujin shop is actually soda water made by local method. The ingredients are baking soda, water, sugar, and citric acid from citrus.

Qin Feng made "soda water" just in the mood of trying it out. After all, he didn't know whether the ancients could accept such a taste.

As a result, the response was super good.

If we can carry forward this "soda water" and "air-conditioning fan", we will definitely earn a lot of money...

Although Qin Feng didn't want to be a corrupt official, the system didn't allow him to be a corrupt official.

But this does not prevent him from being a person who loves money. No matter what age he lives in, the more money, the better for people.

Qin Feng knows the importance of money.

As long as you come in the right way.

As a modern person who has traveled from the future to this point, it would be too low if he couldn't realize the advanced things in his head.

Then the problem is coming.

This method of making "fairy water" is naturally possible, but the production is too cumbersome and the cost is high.

Qin Feng asked someone carefully, there is no such thing as lemon in Dazhou, and citric acid can only be extracted from fruits such as citrus.

Sugar is very common in Dazhou.

The most important thing is "baking soda". Not only is there no finished product, but even soda, that is, soda ash, is very difficult to buy.

Everything can only be made by Qin Feng with his only chemical knowledge.

The method of burning plant ash to obtain soda ash, and then using soda ash to make it is not impossible, but the efficiency is a little low.

The most important thing is actually not these, but ice.

The price of ice in ancient times was really too expensive.

But whether it is the fairy water that Qin Feng sells in the Chunxiang Building, or the "air-conditioning fan" used in the Chunxiang Building, they are all inseparable from ice!

Without ice cubes, soda water can't be so cool, and the air conditioner fan will degenerate into a manual fan. In the hot summer, the wind blowing out may have the same effect as a heater.

I only stayed in Chunxiang Building for half a day that day, and most of the ice in the "air-conditioning fan" was consumed.The big block of ice in the refrigerator was a full 50 taels of silver!

Chunxiang Building might not care, but Qin Feng can't, 50 taels a day, 500 taels a month, it's a waste of money!

And he also hopes that his invention can benefit the common people, so that everyone can enjoy a moment of coolness in summer.

"Air conditioner fan" is just a bunch of wood combined, the cost is not high, and it can be popularized.

But this ice is really too expensive a consumable.

So, Qin Feng racked his brains all day long, thinking about how to reduce the cost of ice prices...

Build an icehouse?Save more for winter?
This idea was first rejected by Qin Feng. Digging an ice cellar and digging ice in winter are not easy jobs.

The labor cost is there, and no matter how much ice is stored, the price of ice will not come down.

If only I could make ice.

This thought flashed through Qin Feng's mind, and he suddenly remembered that he had read in some book that dissolving saltpeter in water would absorb a lot of heat, causing the water inside to condense into ice!
Maybe... this kind of reaction can be used to study the ice-making process?

Qin Feng immediately called Wan Kunming over: "Mr. Wan, do you know something like saltpeter?"

Wan Kunming pondered for a while, and asked back: "What Master Qin said, is it the kind of thing Taoist priests often use when making alchemy?"

"That's right! That's it!"

Qin Feng said excitedly.

"I know a thing or two, but I don't know much..."

Wan Kunming said in embarrassment.

"Just tell me where you can get it!"

Qin Feng urged.

"I don't know about this, so you might as well ask a Taoist priest who can make alchemy."

After Wan Kunming finished speaking, a look of pity suddenly appeared on his face. He looked at Qin Feng and said earnestly, "My lord, there were emperors who pursued immortality in previous dynasties, but Wan thought that longevity is just vain. .”

"Life and death have their own destiny, how can we escape reincarnation? I hope my lord will not be confused and waste all his time chasing illusory things..."

Qin Feng was stunned for a moment before realizing that Wan Kunming was persuading him.

Does this mean he wants to cultivate immortality?

Hahahahaha...

"Don't worry, this county is not that stupid. People live for a lifetime, because they will die one day, and the living will feel that time is precious. If they can live forever, I am afraid that people will lose their fighting spirit and be confused all day long."

"The county doesn't like that kind of day."

Qin Feng patted Wan Kunming's shoulder directly.

"Then Master Qin asked Dan Dao about..."

"Who asked about Dan Dao. I just want saltpeter! Can you find me a Taoist priest? I'll ask..."

Qin Feng put his hands behind his back, looked out of the window, and whispered to himself: "Nitre, it's a good thing. It seems that Dazhou doesn't have any firearms. If I can get saltpeter first and study it, Maybe in addition to making ice, you can also fiddle with gunpowder..."

No matter what happens in the future, it is always good to have a little self-preservation.

Wan Kunming didn't hear Qin Feng's muttering clearly, but he heard clearly that Qin Feng wanted saltpeter.

As long as Qin Feng doesn't pursue longevity like those stupid emperors written in the history books, Wan Kunming can feel at ease and say to Qin Feng: "If you just want saltpeter, you don't need to go to Taoist priests, and you don't need to ask others..."

"Huh? What do you mean?"

Qin Feng was puzzled.

"My lord ordered me and Yan Li to supervise the reclamation of the terraced fields. The two of us dare not take it lightly. The reclamation of the first hill has basically been completed, so I went to the nearby hills to investigate a few days ago, excavated the soil quality, and found that In such an area, there are a lot of saltpeter buried underground..."

"Is this true?!"

Qin Feng excitedly turned around and supported Wan Kunming's shoulder.

"How dare a subordinate speak nonsense?"

"Quick! Take me to have a look!"

Qin Feng immediately ran to the chair, put his robe on his body, and urged Wan Kunming to go into the mountain against the sun.

"Look, my lord, it's here."

Wan Kunming pointed to an area that had been excavated a bit and said.

Qin Feng looked over there, and sure enough, under the shallow soil layer, there are frost-like crystals all over, which are natural saltpeter mines. Looking at the trend of spreading and the degree of density, I am afraid that the reserves of saltpeter mines buried underneath , not a few!
Qin Feng took a deep breath, gritted his teeth, and said to Wan Kunming: "You have done a great job! After you go back, you should send someone here immediately to dig!"

"Is this the excavation?"

"That's right... this is the key to getting rich in Ninghai County!"
