As a result, the cost of transportation is high, and the price of fruits and vegetables will also rise.

Chen Mu felt a little distressed.

After pondering for a while, Chen Mu decided to ask the adults in the capital to study the production method of saltpeter.

Since the merchants who sell saltpeter are not willing to reduce the price, they are not willing to tell the method of refining saltpeter.

Then he can only let people study it himself.

But fortunately, he had heard of the general method, and asked the adults who studied the government to think about it carefully.

It should be possible to refine a batch of saltpeter as soon as possible.

After making up his mind, Chen Mu did not delay and immediately took people back to Beijing.

In the team returning to Beijing, Chen Mu saw a familiar figure, which was Shi Yong's younger brother Shi Hao.

Shi Hao looked at Chen Mu with some embarrassment, and then at Zhao You.

When Zhao You lobbied him to go to the capital before, he still recommended him in every possible way, and he was very resistant.

Now that he has been appeased by His Royal Highness the Prince, he has renewed hope for the political situation in the capital, and he also wants to go to the capital to study and work hard.

His eldest brother was a hard farmer in the first half of his life, but he was later arrested by the county order, squeezed, persecuted, and almost lost his life.

After having to fall into the grass, I finally met a nobleman.

He wants to benefit more people in the future and stand up for hard-working civilians like his eldest brother.

Chen Mu learned of Shi Hao's ambition and was quite satisfied.

The Great Xia Dynasty needs such talents.

After returning to Beijing with people, Chen Mu immediately instructed the matter of ice making.

The adults who studied the government never dreamed of it.

One day, they had to boil dung.

The dung is all chicken and duck dung collected from the towns around the capital.

Several towns and cities have developed livestock farming, and are struggling to dispose of chicken and duck manure.

When I heard that there were adults in the capital who bought them at a high price, the farmers only felt like they were dreaming.

"I really haven't heard of it, this chicken dung and duck dung can be exchanged for money! If I knew that, when I first disposed of the chicken and duck manure, I wouldn't have sprinkled it in the field! That's gold and silver! ”

"I can't say that, this kind of good thing can't happen often, let us bump into this good thing this time, even if it's our luck, don't expect too much."

The people who exchanged chicken dung and duck dung for money returned to the villages and towns happily with the silver.

The adults in the research office had green faces, looking at the truckloads of chicken and duck manure piled up in the backyard.

"A few adults have worked hard."

Master Ye pinched his nose and said angrily.

"His Royal Highness the Crown Prince said that before the saltpeter is studied, he is willing to give each adult ten taels of silver a day as a subsidy."

"A few adults have to do a good job for His Royal Highness the Prince."

When Li Mao and the others heard this, they wanted to cry without tears, they raised their hands and wiped their faces, only to feel that they were stained with the smell of chicken and duck dung.

They were resistant to the plan, but it was the order of His Royal Highness the Crown Prince after all.

They had no choice but to find some clean cloths, cover their heads and faces, and then conscientiously study the method of refining saltpeter.

Chen Mu knew the approximate method, and after telling them the method, Chen Mu guessed that in a few days, they would be able to refine saltpeter.

However, who knows, just a day later, an official came to the palace to complain, saying that there were people making trouble outside the research mansion.

Because the smell wafting from the research office has affected the lives of the surrounding people.

When Chen Mu heard this, the corners of his mouth twitched slightly, and he felt helpless, he could only let the adults who studied the government leave the capital and go to the nearby uninhabited village to do this thing of refining saltpeter.

Li Mao and others were very aggrieved.

Before leaving the capital, he deliberately ran to the palace and cried.

Seeing that they lowered their heads and wiped their tears, and there were bursts of strange smells on their bodies, Chen Mu took a step back.

After enduring and enduring it, he finally endured the action of raising his hand and pinching his nose, he turned his back and walked to the window, and said slowly while pretending to be casual and taking a deep breath of fresh air outside the window.

"I know that you have worked hard for this work, so so when the saltpeter is refined, I will give each of you a sum of silver as a reward."

When Li Mao and the others heard this, they began to cry again.

In fact, they came to the palace to cry, not for the silver at all, they just felt wronged, and they just wanted His Royal Highness the Crown Prince to comfort them.

As the adults who studied the government, they received a large sum of money for every gadget they studied.

There is also a share of the equipment sold, so they all have bulging pockets.

Chen Mu saw them bowing their heads pitifully and wiping their tears, so he spoke again and comforted.

It wasn't until a few people were in a stable mood and left the palace that Chen Mu asked the door of the main hall to be opened for ventilation.

After the unremitting efforts of Li Mao and others, saltpeter was finally refined.

With saltpeter, it is naturally extremely easy to make ice.

Chen Mu asked people to prepare some saltpeter powder and send it to several cities where the trade route passed.

He also informed the county magistrates of those cities of the way to use saltpeter.

And the officials who sold saltpeter could not sit still after hearing that there were adults who studied the government and studied the method of developing saltpeter and made a large amount of saltpeter.

"No, we can't let them rob us of our business for nothing, it's so hateful, what should we do next?"

A middle-aged man wandered around the hall restlessly.

His companion shook his head, equally helpless.

"What's the hurry, isn't it just that the recipe for studying saltpeter leaked out? That's a big deal. ”

"I heard that the people who study saltpeter are a few adults who study the government?"

An old man sitting on the upper hand said slowly, and he put the tea cup in his hand on the table next to him with a faint expression.

When the middle-aged man who was turning around heard this, he immediately responded.

"That's right, it's the adults who studied the mansion, hmph, a group of ordinary people from a poor family, but they dared to press on our heads because they had the blue eyes of His Royal Highness the Prince."

"Even rob us of business! It's just so damning. ”

Speaking of this, the middle-aged man's eyes moved slightly, and he suddenly remembered something.

His face became serious, and he walked in front of the old man and bowed.

"My lord, I think this matter is a little strange, why do you say that they can study saltpeter, isn't this technique and secret recipe for studying saltpeter in our hands? It's hard to ......"

In the entire Great Xia, only one of them could study saltpeter, and they were the only one.

The price of this saltpeter is naturally also their final say.

Talking about such things now, it can also be said that they were caught off guard.

And the old man also frowned when he heard the middle-aged man say this, he nodded, he was also thinking about it.

"Is it possible that someone has leaked the secret recipe for refining saltpeter! It must be the person who studied the government and wanted to use this thing to curry favor with His Royal Highness the Prince! ”

"That's right! We'll have to check it out! ”

When the old man heard this, he sneered and waved his hand.

He didn't think there was anything else to investigate about this matter, only one of them knew how to refine saltpeter in the entire Great Xia.
