In this latest secret letter, Hu Biao first introduced the latest situation on the current Zhuxian Town battlefield in terms of casualties and results.
Then, the conversation quickly changed.
He said that the current consumption is too much, so he is frantically asking for things from Kaifeng City, such as artillery shells, bullets packed in paper tubes, medicines, gauze, alcohol, Congreve rockets, etc.
Anyway, apart from people and food, they want everything on the Zhuxian Town battlefield.
To be honest, even if Lang Qing receives a secret letter every day with the latest situation on the battlefield, he 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 Jin people were able to cope with the crazy attacks.
The key issue is that in the face of the supplies proposed by Hu Biao, most of them are okay. With the productivity in the emergency situation, they can barely support it even if they work day and night.
But there is a fatal point. Currently, there are not enough materials for making gunpowder in stock in Kaifeng City.
To be more precise, the stocks of sulfur and charcoal are quite sufficient, but saltpeter is not enough.
Before the war started, there was still a lot of inventory in the warehouse.
You must know that Kaifeng City has always strictly prohibited defecation and defecation, not only for hygiene reasons; there is also an important consideration, which is to collect urine to produce saltpeter.
Specifically, urine was accumulated in nitrate fields, a method widely used in many base areas of our army during World War II.
First dig a big hole on the opposite side and pour some water and lime into it.
Such an approach can maintain the temperature in the soil and promote the production of nitrifying bacteria.
Then after a few days, a large amount of urine is poured into the pit; after fermentation for more than half a year, the soil at the bottom of the pit and around it will be rich in saltpeter.
As long as it is boiled a little later, you can get some saltpeter with a pretty good content.
Relying on such a tasteful method, the Ministry of Industry stockpiled a considerable amount of saltpeter; but unexpectedly, it was still somewhat insufficient.
Upon seeing this, Yu Hanfeng suggested:
"Give all the primary schools in the city a holiday, and call on all the people in the city to scrape the walls of the toilets. We can get some saltpeter."
The reason why Yu Hanfeng said this is that basically all time travelers know that there are some saltpeter crystals on the walls and corners of the toilet.
I don't know how many time-travelers completed the production of the first batch of gunpowder by scraping the toilet wall.
The only flaw is that the saltpeter output of each toilet is limited. Even if the toilet wall is scraped down, there will not be much inventory.
Fortunately, for such a large city, Kaifeng has an astonishing number of toilets.
After the total amount is accumulated, it is quite a lot. In the end, these saltpeters with flavor can eventually play a very good supplementary role.
It is precisely because of this reason that Lang Qing could only nod his head after hearing such a statement.
He opened his mouth and said: "Okay! Let's do a reward activity by the way. One pound of saltpeter can be exchanged for one pound of horse meat at the street office, or two pounds of sewer, to mobilize everyone's enthusiasm."
Although it is really embarrassing for an eighth-level technician like him to rely on such an inefficient method without technical content.
But in order to win such a war, it seems that I can’t care so much...
Just like that, watching Lang Qing hurried towards the palace, Yu Hanfeng was probably planning to ask for an audience with Emperor Maode, and would start activities today.
After yawning heavily, I finally decided to go back and sleep for two hours.
Even though he is now responsible for the entire city defense and security work, he still has many things to deal with.
But if he really wanted to continue like this, he thought that he would die of overwork before the war was over.
As a result, after taking a few steps, several men in Feiyu suits were speeding towards him.
That's right! It's a beautiful flying fish suit like that of the Jin Yiwei of the Ming Dynasty. After the business department got enough fabrics after having a royal concubine.
Yu Hanfeng, a commander of the Imperial Guard, came up with this kind of flying fish suit based on his bad taste.
Every time you go out on the street with a group of subordinates, coupled with the iconic embroidered spring knife, it is completely trendy, isn't it?
The only pity is that they don't have any extra war horses at all.
Therefore, when the horses were riding fast in the past few days, the person who was constantly being whipped on the crotch was not the divine horse, but just a person and a small donkey.
In the process of flying, the long legs of his guards almost touched the ground. The scene was quite joyful.
After taking a deep breath, I forcibly eliminated the urge to complain.
Facing his confidant Zhen Fu who got off his horse and knelt on one knee in front of him, Yu Hanfeng asked: "What's going on in such a hurry?"
The governor, who was in his thirties and looked capable, did not answer immediately after hearing this.
Instead, he asked a few imperial guards behind him to stand guard at a distance from the surrounding area.
Then in a voice that only the two of them could hear, he spoke in a low voice: "Commander, while I was waiting in the middle of the night, I caught a man trying to secretly shoot an arrow outside the city.
After using some tricks, he has confessed that he is a confidant of the then Prime Minister Geng Nanzhong, and it was Geng Nanzhong who asked him to shoot this letter out of the city."
Upon hearing this, Yu Hanfeng immediately took the letter and read it.
It was discovered that the contents of this letter were entirely related to the situation in the Song Dynasty court and Kaifeng City. It was obvious that only insiders could have done this.
So, the traitor they have been tracking down is Geng Nazhong.
While Yu Hanfeng was reading the letter, the governor continued to speak, which completely confirmed Yu Hanfeng's guess:
"Commander, in the past, we have confirmed that this person is really from Geng Mansion.
In addition, the handwriting on the letter has also been verified by brothers who are good at this. It is the same as the handwriting on the official documents and official documents written by Geng Nanzhong on weekdays. It is definitely not a forgery.
Now another group of brothers has secretly surrounded Geng Mansion, do you want to take action immediately?"
"What the hell! This guy can't live a good life, he's really asking for death." Facing the request of whether to take action, Yu Hanfeng first cursed in his mouth.
In the following time, he fell into hesitation.
Originally, they knew that Geng Nanzhong was a traitor in history, but in this mission world, it had not caused such big consequences.
The reason is not to completely fall out with the old forces, so as to give them more new policies.
At the beginning, a group of netizens decided that as long as this guy honestly acted like a mascot-like prime minister, they could let him die a happy death.
I never thought that this guy would have such a deep collusion with the Jin people.
No wonder that in the past, Kaifeng City mobilized old ladies to prevent Jin spies, but assassinations still happened from time to time.
It turns out that the root lies with such a prime minister of the Song Dynasty.
The problem is that it is very simple to kill this guy, but it is of little significance; making good use of this internal response and passing some false news to the Jin people is a wiser choice.
Maybe, it might even play a key role in this battle.
Just to convey any news, it seems that we need to use the fat Hai Dongqing as an emergency contact method to discuss it with Hu Biao and others.
After thinking of this, Yu Hanfeng asked the key question: "The person was not broken, was he?"
The soothing envoy was also smart and immediately answered: "No, they are all hidden wounds. On the surface, there don't seem to be any wounds."
Hearing this, Yu Hanfeng also breathed a sigh of relief:
"Get the person away quickly to avoid disturbing the situation; I will go to the prison immediately to meet with this person and teach him how to speak when he returns."
In the following time, Yu Hanfeng no longer cared about anything honorable or dishonorable.
After getting on a barking donkey, he hurried towards the prison.
While on the way, I couldn't help but think: "It's been a while since that task force set out, and it stands to reason that it has arrived at Yanshan in the North.
I don’t know if Fengrui, Zhan Xiang, Ali and others have taken action; the more noise they make, the easier it will be for us here.
There are also reports of battles in Xiangzhou that have been cut off for quite some time. I wonder how Grandpa Yue and his friends are doing there..."
