Yang Zhen doesn't know whether there is an iron smelting site in Ningyuan City. After all, the time he traveled through was too short, and he only stayed in Ningyuan City for a few days. When he encountered a question that he didn't understand, he had to ask

Wang Shoutang.

Fortunately, Wang Shoutang was a senior blacksmith from Ningyuan Wangji Blacksmith Shop, and was very familiar with these situations. He immediately said like a familiar treasure:

"In the past few years, 10% of the iron materials of the Wang family in Ningyuan came from Beizhi, Guannei. In the past few years, the iron smelting in Beizhi, Guannei, was destroyed time and time again by the Tatars. The source of iron materials is also inconsistent, and the supply is insufficient!

"So, at present, about 30% of the iron in Ningyuan comes from the Wang family's own smelting, and the remaining 70% still comes from within the pass. Of these 70%, most of it comes from Yongping Prefecture and less than half from Jizhou Town!

"I've heard that there are good iron smelting and good iron materials further south after Shandong, but it's just too far away! In the chaos of war, even the Wang family in Ningyuan and the ancestral family can't get it!"

Having said this, Wang Shoutang shook his head with a wry smile, paused for a moment, looked up and saw Yang Zhen and others looking at him, and then continued:

"Nowadays, the source of iron materials outside Shanhaiguan is most likely in the hands of the Wang family in Ningyuan. The Wang family is the in-law home of Marshal Zu. This time the old man has left the Wang family. We want to get it outside Shanhaiguan.

Iron materials, I’m afraid it’s even more difficult! So this ironworks—”

When Wang Shoutang said this, he stopped with a wry smile again and looked at Yang Zhen. The meaning was self-evident.

When Yang Zhen heard this, he understood the meaning.

He had not considered these details before. He only knew that if he wanted to stick to Songshan for a long time in the future, he must have a group of capable blacksmiths, so he wanted to keep the Wang family and his son.

Now it seems that Wang Shoutang thought very deeply, because a blacksmith without a stable source of iron is equivalent to throwing away his livelihood and job, guarding a Songshan City without a source of iron, let alone giving him a system.

Even if we give him ten or eight iron works, he can only stare!

Wang Shoutang stopped talking, and Yang Zhen was also silent. As a result, everyone present fell silent, as if someone had cast a spell, and they all froze.

After a long time, Guo Xiaowu, who had been silent on the side, suddenly said: "Sir! I heard before that the iron-covered and wooden-handled grenades used by Li Dusi's grenadiers were all made of iron bullets from the Fo Lang machine.

,is that so?!"

Yang Zhen, who was thinking about countermeasures, turned his head and glanced at Guo Xiaowu, who suddenly became a little excited, and said: "Just say what you want to say, why are you making any detours in front of me! Wait - you mean -"

Looking at the excited Guo Xiaowu, a flash of lightning flashed in Yang Zhen's mind. As if he suddenly realized something, he pointed at Guo Xiaowu and said to him excitedly: "You mean - pellet! Iron pellet! You really have a good mind.

use!"

At this point, Yang Zhen ignored the surprised and inexplicable reactions of others and said excitedly to Yan Shengsan in front of him: "Shengsan! Go to the front yard quickly and invite Jin Shijun, the eldest son of Deputy General Jin Guofeng's military master!

I have something important to ask him!"

Yan Shengsan saw that Yang Zhen was so excited, excited and anxious, so he didn't dare to neglect, and immediately ran to the front yard to invite Jin Shijun.

Jin Shijun was left by Jin Guofeng at the Chenghuang Temple camp of the advance camp, mainly to serve as a liaison officer between the two armies. The leader of the advance camp was Yang Zhen, and while Yang Zhen was in the camp, Jin Shijun basically stayed in the front yard of the camp.

value.

Only a moment after Yang Zhen sent Yan Shengsan out, he heard footsteps coming from the second courtyard. Soon, Yan Shengsan was in front and Jin Shijun was behind, and they entered the backyard.

"Brother Shijun! Come here quickly! Come here quickly! Yang has something to say and I can't wait to ask you!"

As soon as Jin Shijun entered the hospital, Yang Zhen changed his usual calm demeanor and started yelling at him with a big smile.

Jin Shijun is about twenty-five or six years old. He is tall and straight, and his appearance is similar to that of his father Jin Guofeng. He has bright eyes that look like a smile but not a smile, but his face is slightly darker, but he looks more heroic and imposing.

Jin Shijun met Yang Zhen and was about to salute, but Yang Zhen grabbed him and prevented him from saluting. Yang Zhen said: "No need to be more polite! Your father is your father and you are you. I will discuss it with you alone."

pay!"

When Jin Shijun saw Yang Zhen acting like this, he could only smile and said repeatedly: "I don't dare to take it! I don't dare to take it! I wonder if General Yang has anything to ask about?"

"Let me ask you! This time Songshan City was surrounded by the Tatar army. How many days did it last? How many days did the Tatar army bombard Songshan City? How many Tatar heavy artillery were there outside the city, front and back?

How many rounds were fired in total?!"

As soon as Jin Shijun met Yang Zhen, he was questioned by Yang Zhen. If it weren't for the excited smile on Yang Zhen's face, Jin Shijun would have doubted whether Yang Zhen's question was harmful to the soldiers guarding the Songshan city.

conspiracy.

"General Yang, if you ask me this, I really can't tell you for a while! The Tatars besieged Songshan, which started in the middle of the first month of the first lunar month, and lasted for the whole of February until you entered the city yesterday! It took about fifty or sixty days.

!——General should know these situations, I wonder why General Yang asked this question?!"

"Brother, please don't worry about why I'm asking you this. Just tell me first and I'll probably listen and figure it out!"

Faced with Jin Shijun's questions, Yang Zhen did not answer, but just urged Jin Shijun to answer his own questions.

Jin Shijun had no choice but to touch the short beard on his chin, thinking while answering: "In the beginning, the Tatars only cut down trees to set up camps, dug trenches to besiege the city, and never used heavy artillery to bombard the city walls. At that time, my father also led the city garrison.

The army went out of the city and robbed the camp several times!

"In late February, the slave chief Huang Taiji personally led the Tatar army and shot a book into the city. He said that he had brought more than 40 red barbarian cannons from Shengjing of the Tatars and persuaded my father to surrender! Otherwise, he would use heavy artillery fire.

Collapse the city wall, and no one in the city will be left alive! The letter was torn up by my father in public, and the messenger was shot to death under the city by my father's command!

"After that, the Tatars began to bombard the city with their heavy artillery! For several days in a row, the Tatar heavy artillery was extremely dense. When we walked in Songshan City, we had to have several people holding the door panels together!

"——You saw it when you entered the city. Not only were the city walls covered with bomb craters in the West City and South City, but countless shops and houses in the city were also destroyed!

"A projectile from the Tatar Red Cannon can weigh up to 16 or 7 kilograms! If it hits the city top, it will pierce gold and crack rocks! If it hits the crowd, it will cause flesh and blood to fly everywhere, and those who are hit will die immediately!"

"On the days when the Tatars attacked the city most violently, day and night, bullets rained down on the city walls! First in the south city, then in the west city, the buildings collapsed! Thousands of soldiers and civilians in the city had to take shelter at the base of the city wall.

Get off! Alas—"

Having said this, Jin Shijun seemed to be trapped in a painful memory, sighed, muttered, and finally stopped talking.

Seeing Jin Shijun like this, Yang Zhen couldn't bear it. The excitement just now had passed. He sighed and said to Jin Shijun:

"Then it seems that the Tatars' Hongyi heavy artillery bombardment of Songshan City must have left countless projectiles inside and outside the city wall! If each projectile weighs sixteen or seventeen kilograms, this is quite a fortune!

"

Jin Shijun, who was immersed in painful memories, heard this and raised his head blankly, looking at Yang Zhen, as if wondering what Yang Zhen meant by what he said.

However, as soon as Yang Zhen said this, several people who had been discussing the iron material problem all understood in an instant. Everyone sighed in their hearts, "So that's how it is", with uncontrollable smiles on their faces.

"General Yang came to me for this purpose?! If the general thinks that the projectiles fired by the Tatars into the city are still useful as iron materials, then there will be too much!"

After Jin Shijun reacted, the expression on his face was wonderful. He didn't know whether to stay sad or smile. At the same time, what Yang Zhen said filled his heart with shock. The expression on his face was...

He switched between several types in a moment, and finally took a deep breath and said again:

"The Tartars besieged the city for fifty or sixty days. During this period, more than half of the city was bombarded with artillery, sometimes day and night. To put it into perspective, the Tartars had more than forty red barbarian cannons, plus other kinds of artillery.

Hitting the city head one after another, there are probably not tens of thousands of projectiles that hit the city! Even if a small part of the stone bullets are not included, there are not nine thousand iron projectiles, but there are always eight thousand!

"

When Yang Zhen heard this, he nodded to express his approval of the number, then turned to look at Wang Shoutang, and asked Wang Shoutang calmly: "Mr. Wang! You do the math first! The Tatars invaded the city or entered the city.

The eight or nine thousand iron bullets that fell outside the city, each weighing seventeen kilograms, have left us with a total of how much iron material? How long can we use them?"

Yang Zhen's mood returned to calm, but it was the turn of the people around Yang Zhen to become excited, and they all started counting happily.

Wang Shoutang has been running the blacksmith shop for decades and has been calculating these things. After listening to Yang Zhen's words, he quickly came up with his own calculation results:

"Sir! If we calculate it based on eight thousand pieces, let's calculate that one piece weighs seventeen kilograms. I'm afraid there won't be - I'm afraid there won't be 136,000 kilograms of iron! One hundred and thirty-six thousand kilograms!
