A landmine is an explosive firearm that is buried under the surface of the earth or laid on the ground.

According to Su Ziheng's knowledge, the earliest landmines on the earth in the previous life originated in the Great Song Dynasty of China, when it was called "gunpowder cannon". Then, after continuous improvement, real mines with mechanical firing devices appeared.

Su Ziheng originally wanted to directly invent standardized and diversified modern mines, but the craftsmanship of this era was not up to par. In desperation, he had no choice but to use the ancient method to make it in the way recorded in the "Fire Dragon Sutra".

"The bombing is made of cast iron, on an empty stomach, with a pestle of medicine, into a small bamboo tube, through the fire line inside, and with a long line through the fire trough outside. Choosing the only way to go, dozens of people were buried in the pit, the medicine trough was connected to the steel wheel, and the soil was covered, so that the thief did not know, and the engine was moved, and the shock was raised, and the iron was like flying, and the flames were soaring to the sky. ”

Even Su Ziheng made some improvements, using a steel wheel to ignite, when the enemy stepped on the motive, the steel wheel rotated and violently rubbed against the flint to ignite, detonating the mine.

At present, the mines made by Wang Boyang, the son of Danyang, are this kind of mines. It is also thanks to the last time that Zhong Qinghan sent a lot of iron ore when manufacturing cement, otherwise Su Ziheng would not have been able to get so many pig iron casting shells.

Rao had enough raw materials for pig iron, but he didn't have blacksmiths who were skilled in weapon casting, so he could only go to the craftsmen in the workshop to grope and make dozens of mine shells.

It is precisely because of the scarcity of mines that Su Ziheng did not use it for arming. One is that the number of mines is small, and the lethality of non-concentrated use is insufficient; The other is that it is easy to lay mines, and it will be very troublesome to clear mines at that time. After all, Sujiazhuang is where he lives, and it is not cost-effective to injure the people of the manor by mistake.

Outside the manor, after using a mine for experiments, he pressed a corpse of a Mengyuan soldier on it, and after the mine was triggered, he actually blew the corpse away, which made him very satisfied.

Su Ziheng called Shi Meng and ordered: "Mengzi, take half of the courtyard, pull these corpses and heads to the north corner of Jiufu Mountain in a few carriages, and we will go there to give a big gift to the Mengyuan people." ”

Shi Meng responded and beckoned a few people to go to the carriage.

Su Ziheng called Ma Lao Liu and the housekeeper Qian Lu again, "Uncle Qian, I will trouble you to arrange a few family members to clean up all the good armor on the Mengyuan soldiers." By the way, there are weapons that can't be missed, and even if you can't use them, you can recycle the iron. ”

Qian Lu smiled all over his face, and hurriedly responded: "No trouble, no trouble." Master, the old slave understands, and he will definitely not waste it. ”

Su Ziheng said: "Ma Lao Liu, look at these war horses, if they are not injured, arrange a few people to settle them first; If you are seriously injured, you will slaughter and take the meat, and then hold a celebration banquet when everyone has finished cleaning up the battlefield. ”

Ma Lao Liu also nodded his head again and again, beckoned more than a dozen family members, and went to inspect the war horse.

……

……

More than 50 people worked together, and it took nearly an hour to dig a big pit, throw all the corpses of Meng Yuanjun into the pit, and bury them with soil.

Then on top of the soil pit, a Jingguan was built with the heads of a thousand Mengyuan cavalry, and the dozens of mines were buried near Jingguan, no matter when the Mengyuan army approached Jingguan from that direction, it would be blown up by the mines.

Come and don't be rude, this is a big gift from Su Ziheng to the Mengyuan army!

After setting up the trap, Su Ziheng asked Li Dashan, who came with the team, "Uncle Li, do you know how to ride a horse?" ”

Li Dashan said with a smile: "Master, how many of the hunters in Liangzhou can't ride horses?" Although the small ones are not as superb as those Mengyuan barbarians, they can also shoot arrows on horses. ”

can shoot arrows on horses, and the riding skills are naturally not weak.

Su Ziheng nodded and said: "Then please trouble Uncle Li, you take care of it from a distance here, if there is a wild beast approaching, just release arrows to drive it away, don't get close, lest you fall into the trap." In addition, once the traces of Meng Yuanjun are found, do not entangle with them, leave this place as soon as possible, and return to Zhuangnei to report the news. ”

Li Dashan sighed, "The little one understands, and he will definitely not delay your business, master." ”

Su Ziheng said: "Well, I'll arrange someone to accompany you to guard it later, and the two of you will also take care of it." If Meng Yuanjun doesn't come at night, I will arrange for someone to come over and continue to guard you. In the evening we have a celebration party! ”

As soon as they heard Su Ziheng say that there was a celebration banquet in the evening, everyone was overjoyed, and their faces showed a look of longing.

To say that this is more than 1,000 beheadings, not to mention that they are an ordinary household, even in the army, it is a great merit, and it is indeed worth holding a celebration banquet. If he wasn't worried that Meng Yuanjun would come in the afternoon, Su Ziheng would be able to start the celebration banquet at noon.

This is a very good opportunity to win the hearts and minds of the people!

Back in Sujiazhuang, the battlefield outside had been cleaned, the blood stains on the ground had been covered with a new layer of soil by the servants, and the potholes had been blown up by grenades, and the ground had been repaired with sand and gravel.

"Master, are you back? Those weapons and horses have been placed, do you want to go and see them? The housekeeper Qian Lu greeted him with a smile.

Su Ziheng nodded and said, "Uncle Qian, it's good if you take me to see the war horse, and I'm sure Uncle Qian will definitely be wrong with other things." ”

After receiving Su Ziheng's praise, Qian Lu's eyes were almost narrowed into a slit with a smile. Hurriedly led the way in front of the head and led Su Ziheng to the stable.

At a glance, the stables were crowded with war horses, and it was impossible to tell how many of them were for a while.

Su Ziheng smiled and asked, "Uncle Qian, have you counted how many war horses there are?" ”

Qian Lu hurriedly said: "There are a total of two hundred and fifty-six horses that are intact, and the other horses that have suffered some minor injuries add up to more than five hundred and thirty horses. However, the injured horses were not housed in this stable, and I was afraid that they would not be able to let go. ”

"Only more than 500 horses? It seems that the lethality of this grenade is still too fierce, so it should be used with caution in the future. Having said that, Su Ziheng is still very satisfied with this harvest, at least he didn't lose anything, and he made a lot of money.

At present, the price of a horse in the market is almost eighty taels of silver, which is still an ordinary horse. The price of a war horse will be at least several times higher, and if you encounter the kind of high-grade war horse that is one in a hundred, the price will be calculated in a thousand taels of silver.

Even at an average price of 100 taels, more than 530 war horses are worth more than 50,000 taels of silver. And he only spent a small amount of gunpowder, which can be said to be a million profits.

However, the loot is easy to take, and the risk is not small, and the follow-up revenge of the Mengyuan cavalry has to be considered. Otherwise, in the end, even the principal and interest will have to be taken back by others.

On the one hand, Su Ziheng arranged for the kitchen to prepare a celebration banquet, and on the other hand, he gathered dozens of craftsmen from the workshop and arranged for them to hurry up the time to make granular black powder and produce pottery grenades in large quantities.

He knew in his heart that the main reason for such a good result this time was that Babur was too light on the enemy, and he gathered all the cavalry in one place before he was served with a grenade.
