Flowers in full bloom

Chapter 781 Letter from Relatives

This is the nitrate water rich in saltpeter. The process of using water to leach the saltpeter out of the nitrate soil is called "leaching saltpeter".

When pouring saltpeter, you can use a fresh egg to judge the content of saltpeter remaining in the saltpeter soil. The worker just needs to put the egg in the pool. If the egg can float to the surface, it means that the saltpeter content in the pool is high.

If the egg sinks into the water, it means that the nitrate content in the nitrate soil is not much. You can stop applying nitrate and change a batch of saline-alkali soil and apply water again.

When enough deep red nitrate water has been poured out, pour it into the pot, turn up the fire, and after the nitrate water in the pot boils, turn down the fire and simmer over low heat until the nitrate water becomes thick.

Add a small amount of liquid saltpeter and wait for it to cool down. If it becomes solid, it means the liquid saltpeter has been boiled and the fire can be stopped. Saltpeter has been extracted.

Then, the staff will slowly scoop out the remaining liquid in the pot. At this time, you can see white crystals all over the bottom of the pot. This is the nitrate salt, and the scooped out nitrate water is brine.

Saltpeter can be used to make ice, nitrate can be used to pickle pickles, which will not go bad even if left for a long time. And brine can be used to make tofu and fertilizer, both of which have good effects.

Diluting the brine with water and using it to irrigate crops can significantly increase crop yields.

However, harmful gases may be produced during the saltpeter refining process, so a shed was built above the saltpeter pool to maintain a good ventilation environment.

However, it is easier said than done. It was not until a month later that Hua Lei saw saltpeter extracted from the saline-alkali land.

The saltpeter refining description that Hualei had sent to him at the earliest opportunity had already been filed with the Ministry of Industry and had received permission. From now on, the amount of saltpeter extracted and its destination would be reported to the Ministry every quarter or half a year.

After the saltpeter was extracted, Hua Lei handed the matter over to Changhuai Prefecture's Lin Zhizhou and his subordinates, the Prefecture Yamen Lifang. The entire set of subsequent management and supervision issues were all in the hands of Changhuai Prefecture's Lifang, with responsibilities assigned to individuals.

All the in and out records of saltpeter were kept, and then a suitable shop was found near the border market, a cellar was dug in the backyard, and an ice-making workshop was set up. The ice cubes produced were sold at the border market nearby.

After the saltpeter refinery was slowly running, Hualei returned to the government office. The desks in the government office were piled with documents that needed to be processed urgently. It took five or six days to deal with the documents. Among them, there were several letters.

One letter was sent by Bao, the governor of Xi'an Prefecture. He asked Hualei for advice on the next peanut planting, and Hualei did not keep any secrets.

I sorted out my experience in peanut planting and sent it to him. However, I didn't give him the "Stones from Other Mountains" and "The Collection of Flames" that I had in my hands.

Sometimes, what you think is a timely help or icing on the cake may be seen as showing off or flaunting in the eyes of others.

There was another letter from Rong Jin's uncle. After opening the letter, I found out that it was actually written by Rong Jin's aunt. The letter mentioned Han Qingge and Fan Siyu.

Lin expressed her gratitude to Rong Jin for supporting Han Qingge. However, this Lin was too unkind.

In the letter, she only thanked Rong Jin, but did not mention Hua Lei's efforts. Rong Jin's face was very ugly, but Hua Lei did not care.

Because, in her hand, there are still a few letters from Shangjing City. One is sent by her parents Hua Mancheng and Yun Siwan.

In the letter, Hualei was told that Xiaoyuan had become a father. In early May, Ruan Meizi gave birth to a big fat boy, and both mother and child were safe.

The whole family was very happy. Xiao Yuan was very happy, but he also proposed to Hua Mancheng and Yun Siwan that he wanted to take Miss Ruan with him for a transfer at the end of the year.

Now Xiao Yuan, after winning the first place in the imperial examination, went directly to the Hanlin Academy. He served as a sixth-rank tutor, responsible for reading classics and history to the children of the royal family. He was extremely noble.

When he first entered, Xiao Yuan was very satisfied. However, after half a year, he began to think about transferring to another position.

However, at the time, Ruan Meizi was only four or five months pregnant. Not only Hua Mancheng and his wife opposed it, but also his father-in-law and mother-in-law. Therefore, Xiaoyuan suppressed the idea of ​​transferring her to another place.

Now that the child is born, Xiaoyuan's desire to transfer to another place has been aroused again.

However, Hua Mancheng might have remembered that he insisted on going to Changyun County to serve as the magistrate, but in the end he didn't even see his parents for the last time, leaving his two children alone and helpless.

Therefore, Hua Mancheng disagreed with Xiaoyuan's transfer. Yun Siwan was even more opposed. However, because the couple felt guilty towards the siblings, they could not stop them in person.

So, recently, Hua Mancheng has been sighing every day, and Yun Siwan has been secretly crying every night, and she has lost a lot of weight.

The couple wrote this time with the same idea, that is, they wanted Hualei to persuade Xiaoyuan to give up the idea of ​​transfer. The two siblings have been dependent on each other since they were young and grew up together. Xiaoyuan obeyed Hualei's words.

After reading the letter from her parents, Hualei couldn't help but sigh. She understood her parents' thoughts, especially after the couple was hunted down and almost died.

Because they had no money for the trip, they were stranded on the way and lived a life of poverty. For them, this was a nightmare that they could not bear to look back on.

Xiaoyuan's transfer to another place was a matter of life and death, so of course they were against it. Now, they just wanted to be a family reunion in peace, and they didn't want the same tragedy to happen to their family again.

Moreover, Xiaoyuan works in the Hanlin Academy and has a bright future. After some experience abroad, he will be transferred back to the capital in the end. Why should he go somewhere far away?

Hualei could also understand Xiaoyuan's idea of ​​being transferred out. Xiaoyuan grew up with her and was very smart. She sometimes talked to him about his past life. Xiaoyuan must be yearning for it.

In addition, Xiaoyuan had been to Mobei before and studied with the Master for a period of time. He also felt the suffering of the people's livelihood. It was normal for him to hope to use what he had learned to change the current situation and benefit the people.

Moreover, Hua Lei also felt that her words and deeds would sometimes subtly influence Xiao Yuan, who felt that she, as a woman, was transferred to another place.

Xiao Yuan felt that as a man, he should go out, and his idea became stronger. Looking at Hua Mancheng's letter, Hua Lei was very embarrassed.
