Chapter 487 Saltpeter and Internal Response

In the latest secret letter, Hu Biao first introduced the latest situation of the current Zhuxian Town battlefield in terms of casualties and results.

Then, there was a quick change of subject.

Speaking of which, because the consumption is too much at present, he frantically asks Kaifeng City for things, such as shells, bullets packed in paper tubes, medicines, gauze, alcohol, Congreve rockets, etc.

Anyway, apart from people and food, they wanted everything on the battlefield in Zhuxian Town.

In fact, having said that, Lang Qing, who can receive a secret letter about the latest situation on the battlefield every day, naturally knows how difficult the situation there is.

The supplies that should be prepared are being consumed so quickly.

It can be said that relying entirely on steel and gunpowder, the Jinren's frenzied attack was successfully dealt with.

The key issue is that in the face of all the materials proposed by Hu Biao, most of them are okay, and relying on the productivity in emergency situations, they can still barely support them after working day and night.

But there is a fatal point. At present, there are not enough materials for making gunpowder in Kaifeng City.

To be more precise, the stocks of sulfur and charcoal are quite sufficient, but the material of saltpeter is not enough.

Before the war, there was still a lot of inventory in the original warehouse.

You must know that in Kaifeng City, defecation has been strictly prohibited before, not only for hygiene; there is also an important consideration, that is to collect urine to produce saltpeter.

Specifically, it is to use the accumulation of urine in the nitrate field, such a method was widely used in many base areas of our army during World War II.

First dug a big pit on the opposite side, poured some water and lime into it,
Such a practice can maintain the temperature in the soil and promote the production of nitrifying bacteria.

Then after a few days, pour a large amount of urine into the pit; after more than half a year of fermentation, the bottom of the pit and the surrounding soil will contain rich saltpeter.

As long as it is boiled later, you can get some saltpeter with a fairly good content.

Relying on such a tasteful method, the Ministry of Industry hoarded a considerable amount of saltpeter; but unexpectedly, it was still not enough.

Seeing this, Yu Hanfeng suggested:

"Give the elementary schools in the whole city a holiday, and call on the people of the whole city to scrape the walls of the toilets together, so that we can get some nitrate."

The reason why Yu Hanfeng said this is that basically all the traversers know that there are some saltpeter crystals on the walls and corners of the toilet.

I don't know how many traversers completed the production of the first batch of gunpowder by scraping the toilet wall.

The only drawback is that the output of saltpeter in each toilet is limited, even if the wall of the toilet is scraped down, there will not be much stock.

Fortunately, in Kaifeng, a huge city, the number of toilets is quite amazing.

After the total amount is piled up, it is quite a lot. In the end, these saltpeter with taste can also play a quite good supplementary role in the end.

It is precisely because of this reason that after hearing such a statement, Lang Qing could only nod his head.

He opened his mouth and said, "Okay! By the way, we will hold a reward event. One catty of nitrate can be exchanged for one catty of horse meat at the street office, or two catties of water can be used to mobilize everyone's enthusiasm."

Although for a level [-] mechanic like him, it is really embarrassing to say that he has to rely on such inefficient means with no technical content.

But for the victory of such a war, it seems that I can't care so much...

Just like that, seeing Lang Qing rushing towards the palace, Yu Hanfeng, who probably planned to see Empress Maode, started the activity today.

After yawning heavily, he finally decided to go back to sleep for two hours.

Even if he is now in charge of the entire city defense and security work, he still has many things to deal with.

But if he really wanted to go on like this, he thought that before the end of this battle, he would die from overwork first.

In the end, after taking a few steps, several men in flying fish suits galloped towards him.

That's right!It was a beautiful flying fish suit like that of Daming Jinyiwei, after the businessman who had a noble concubine got enough fabric.

Yu Hanfeng, the commander of Jinyiwei, made this kind of flying fish suit out of bad taste in his heart.

Every time you take a group of people out on the street, and pair it with the iconic Xiuchun knife, it's completely cool to the extreme, isn't it?
The only pity is that they have no spare horses at all.

So when riding fast in the past few days, it was not Shen Jun's war horse that was constantly being whipped in the crotch, but a person and a little donkey.

In the process of speeding, the long legs of the guards under him almost stepped on the ground, and the scene was quite joyful.

After taking a deep breath, he forcibly eliminated the urge to complain in his heart.

Facing a confidant who knelt down in front of him after getting off his horse, Yu Hanfeng asked, "Why are you in such a hurry?"

The pacifier in his thirties with a dry face did not answer immediately after hearing the words.

Instead, let a few Jinyiwei behind him guard the surroundings for a certain distance.

It was with a voice that only two people could hear, and said in a low voice: "Commander, when I was waiting in the middle of the night, I caught a man who was trying to secretly shoot arrows outside the city.

After resorting to some tricks, he has already confessed that he is the confidant of Prime Minister Geng Nanzhong, and it was Geng Nanzhong who asked him to shoot the letter out of the city. "

Upon hearing this, Yu Hanfeng immediately read the letter after receiving it.

It was discovered that the contents of this letter were all about the situation in the Song court and Kaifeng City, and it was obvious that only internal agents could do this.

In other words, the traitor they have been tracking down is Geng Nanzhong.

And when Yu Hanfeng was reading the letter, the eunuch continued to speak, completely confirming Yu Hanfeng's conjecture:
"Commander, in the past time, we have confirmed that this person is really a member of the Geng family.

In addition, the handwriting on the letter has also been verified by brothers who are proficient in this way, and it is almost the same as the handwriting on Geng Nanzhong's daily memorials and official documents, and it is definitely not a forgery.

Now another group of brothers have secretly surrounded the Geng Mansion, should we do it immediately. "

"What the hell! This guy is living a good life, but he is really looking for a dead end." Facing the request for instructions on whether to do something, Yu Hanfeng cursed first.

In the following time, he fell into hesitation.

Originally, they knew that Geng Nanzhong was a treacherous minister in the original history, but because in this mission world, it has not caused such a big evil result.

The reason is not to completely fall out with the old forces, so as to make their New Deal more.

At the beginning, all their netizens decided that as long as this guy honestly acts as a mascot-like prime minister, he can die well.

I never thought that this guy would have such a deep collusion with Jin Ren.

No wonder Kaifeng city had mobilized the old lady to prevent the spies of the Jin people in the past, but assassinations still happened from time to time.

It turned out that the roots fell on such a prime minister of the Song Dynasty.

The problem is that it is very simple to kill this guy, but it doesn't make much sense; it is a wiser choice to make good use of this internal response and pass some fake news to the Jinren.

If it doesn't work, it can still play a key role in this battle.

Just to convey any news, it seems that the second fat Haidongqing has to be used as an emergency contact method to discuss with Hu Biao and others

After thinking of this, Yu Hanfeng asked the key question: "Is the person not broken?"

The appeasement envoy was also clever, and immediately replied: "No, they are all hidden wounds, and there doesn't seem to be any wounds on the surface."

Hearing this, Yu Hanfeng also heaved a sigh of relief:

"Remove the person quickly, so as not to startle the snake; I will go to the prison to meet this person immediately and teach him how to speak after returning."

In the following time, Yu Hanfeng didn't care about any decent and dishonorable things anymore.

After getting on a donkey, he hurried towards the prison.

On the way, I couldn't help thinking: "It took a while for that contingent to leave, and now it is reasonable to arrive at Yanshan in the Northland.

I don't know if Feng Rui, Zhan Xiang, A Li and others have taken action; the more they make noise, the more relaxed we are here.

Also, the battle reports in Xiangzhou have been cut off for a long time, I don't know how Grandpa Yue and the others are fighting there..."
