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

Then, it's a quick turn.

said that at present, because the consumption is too great, he is frantically asking for things in Kaifeng City, what shells, bullets ordered in paper tubes, medicines, gauze, alcohol, Congreve rockets, etc.

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

In fact, having said that, even if he can receive a secret message every day about the latest situation on the battlefield, he naturally knows how difficult the situation there is.

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

It can be said that it was completely relied on steel and gunpowder to cope with the frenzied attack of the Jin people.

The key problem is that in the face of Hu Biao's proposals, most of them are okay, and they can barely support them by relying on the productivity that has entered the emergency situation.

But there is a fatal point, the current inventory of materials for making gunpowder in Kaifeng City is not enough.

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

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

You must know that in Kaifeng City, defecation and defecation have been strictly prohibited before, not just for hygiene; Another important consideration is the collection of urine for saltpeter.

Specifically, it is the use of nitrate fields to accumulate urine, which is a method widely used in many base areas of our army during World War II.

First dig a big pit on the opposite side, pour 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; As long as it has been fermented for more than half a year, it is rich in saltpeter at the bottom of the pit and in the surrounding soil.

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

Relying on such a taste-great method, the Ministry of Industry hoarded a considerable amount of saltpeter; But I didn't expect that it was still a little insufficient.

Seeing this, Yu Hanfeng opened his mouth and suggested:

"Give the city's primary schools a holiday, and call on the people of the city to work together to scrape the walls of the toilets, and you 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, relying on the operation of scraping the toilet wall, completed the production of the first batch of gunpowder.

The only drawback is that the production of saltpeter in each toilet is limited, and even if the toilet wall is scraped down, there is not much inventory.

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

The total amount is also a lot after accumulating, and in the end, these saltpeters with flavor can also play a pretty good role in supplementing.

It is precisely because of this truth that when he heard such a statement, Wolf Qing could only nod.

The mouth opened and said, "Okay! By the way, there is a reward activity, and one pound of nitrate can go to the street office to exchange for a pound of horse meat, or two pounds of water, so as to mobilize everyone's enthusiasm. ”

Although for an eighth-level technician like him, it is really a shame to rely on such inefficient means with no technical content.

But for the sake of victory in such a war, it seems that there is not so much to care about......

In this way, watching Wolf Qing hurriedly head towards the palace, it is estimated that Yu Hanfeng, who is planning to see Emperor Maode and start the event today.

After yawning heavily in his mouth, 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 N things to deal with.

But if he really wants to continue like this, he thinks that before this war is over, he will die of overwork first.

As a result, after taking a few steps, several men in flying fish suits galloped towards him.

That's right! It is a beautiful flying fish suit like Daming Jinyiwei, after the business department with the noble concubine got enough fabric.

Yu Hanfeng, such a commander of the brocade guard, based on the bad taste in his heart, made this flying fish suit.

Every time I go out on the street with a vote of subordinates, I am paired with the iconic embroidered spring knife, which is completely popular, right?

The only pity is that they don't have any extra horses at all.

So when the first few horses were fast, it was not the war horse of the god horse that was constantly whipped under the crotch, but a person and a small donkey.

In the process of galloping, the brocade guards under him, a pair of hanging long legs were about to step on the ground, and the picture was quite joyful.

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

Facing a henchman who turned over and dismounted, knelt down on one knee in front of him, Yu Hanfeng asked in his mouth: "Why are you in such a hurry?" ”

The capable-looking pacification envoy in his thirties did not answer immediately after hearing this.

Instead, he let a few brocade guards behind him guard a distance from the surroundings.

In a voice that only the two of them could hear, he whispered: "Commander, I waited in the middle of the night to catch a man who tried to secretly shoot arrows outside the city.

After using some means, he had already confessed that he was the confidant of Geng Nanzhong, the prime minister of the dynasty, and it was Geng Nanzhong who asked him to shoot the letter out of the city. ”

As soon as he heard this, Yu Hanfeng immediately took the letter and read it.

It was found that the content in this letter was completely some situations in the Great Song Dynasty and Kaifeng City, and it was obvious that only Neiying could do this.

So, the traitor they have been tracking down is Geng Nanzhong.

And when Yu Hanfeng read the letter, the envoy continued to speak, which completely confirmed Yu Hanfeng's guess:

"Commander, in the previous time, we have confirmed that this person is really from Geng's mansion.

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

Now another group of brothers have secretly surrounded the Geng Mansion, do you want to do it immediately. ”

"Special! This guy has a good life, but he really killed himself. Faced with the request for instructions on whether to do it, Yu Hanfeng first scolded in his mouth.

In the ensuing time, he fell into hesitation.

Originally, they knew that Geng Nanzhong was a great traitor in the original history, but because in this mission world, it had not caused such a big consequence.

In order not to completely fall out with the old forces, so as to make their new deal more effective.

At the beginning, a group of netizens also decided that as long as this thing was honestly a mascot-like prime minister, he could also be allowed to die a good death.

I never thought that this product would have such a deep collusion with the Jin people.

It's no wonder that in the previous time, the old lady of Kaifeng City mobilized to prevent the spies of the Jin people, but assassinations still happened from time to time.

It turned out that the root fell on the body of such a great Song Prime Minister.

The problem is, it's very easy to kill this thing, but it doesn't mean much; It is a wiser choice to make good use of this internal response and pass on some fake news to the Jin people.

If you don't do it, you can still play a key role in this battle.

It's just to pass on some news, it seems that you have to use such an emergency contact method as the second fat Hai Dongqing to discuss it with Hu Biao and others

After thinking of this, Yu Hanfeng opened his mouth and asked the key sentence: "The person is not broken, right?" ”

The soothing envoy was also clever, and immediately replied: "No, they are all dark wounds, and there don't seem to be any wounds on the surface." ”

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

"Evacuate the people quickly, lest they startle the snakes; I'll go to the prison meeting and teach him how to speak when he gets back. ”

In the following time, Yu Hanfeng didn't care about any decent or undignified things.

After turning over a donkey, he hurried towards the prison.

When I was on the way, I couldn't help but think: "That task force has been set off for a while, and now it stands to reason that it has also arrived at Yanshan in the Northland.

I don't know if Fengrui, War Elephant, Ah Li and others, have they taken action; The more they toss, the easier it is for us here.

And the battle report in Xiangzhou has also been cut off for a long time, I don't know how Grandpa Yue and their fight are there......"
