Daming's iron armor is extremely expensive, and the third lady once said that the construction cost of Beijing's iron armor can completely buy the entire Beiyu, which is not nonsense or touting the Ming Dynasty, but a fact.

To this day, in addition to the iron armor of Zhu Yijun and Prince Zhu Yijun of the Ming Dynasty, or the armor of Mingguang, there is no iron armor made of homogeneous steel plates, and the iron armor used by the Emperor of the Ming Dynasty is artificially forged, and the construction period of this thing is too long and too long.

There is not much difference between the forging method of iron armor used by the emperor and the iron armor used in Beijing in the initial manufacturing process.

Iron, coal, limestone and other materials are loaded into the hopper, under the traction of the hinge, from the throat of the furnace into the belly of the furnace, bypassing the hot air pipe of the furnace body through the bellows pressurized from the tuyere into the belly, the fully burned coal produces high temperature, the iron is melted into iron juice, the craftsmen insert the pliers into the slag outlet, the glaze initially formed by impurities, pull out from the slag outlet, open the tap hole and start to flow out of the iron liquid.

These glazes, used for paving are excellent and will not go to waste.

The molten iron flows into a square pool, through stirring, so that the air and the molten iron are fully contacted, the cold air enters and does not let the temperature of the molten iron drop, but the temperature of the molten iron will rise further, because the combustion needs oxygen, through the stirring air and the hot molten iron fully contacted, the carbon in the molten iron will burn again.

At this time, you will get a pool of [wrought iron rich in a lot of impurities].

This practice is extremely inefficient, and it is necessary to frequently replace the wood for mixing, the wood simply cannot hold a few times, and under the high temperature roasting, it is easy to cause accidents, often people fall from the edge of the pool into the pool water, the craftsmen of the Ming Dynasty designed a cylindrical blowing steel front package that can be tilted.

This type of front bag has air holes to fill the heated air into the molten iron, and tilting allows the molten iron to burn more fully with the air.

This step of improvement, the Xishan Coal Bureau took a full seven years, since Wang Chonggu led the Xishan Coal Bureau, has been making improvements, and finally can get a large amount of wrought iron in batches under the premise of basically ensuring the safety of craftsmen.

Wrought iron has a very low carbon content, so it is very soft and soft because the carbon in the molten iron has burned out when stirred.

At this step, the imperial armor of the Ming Emperor has entered the stage of pure manual building, through a large number of manual forging, the impurities in the wrought iron are removed, heated and forged, and then carburized again and again, and then began to carburize by various means, the most extravagant method is to put the wrought iron that is repeatedly forged to remove impurities into a large amount of salt and toner and then melt, and throw the wrought iron without too many impurities into it and cook it for two days and two nights, and a piece of [homogeneous steel plate] is manufactured, and then from the steel plate to the emperor's Mingguang armor.

Whether it is manual or salt melting, it is too expensive to carry out mass production at all, let alone arming the Beijing camp, even His Majesty's cavalry cannot be fully equipped.

The process needs to be improved, referring to the manufacturing process of Daming's 'steel needle', Wang Chonggu led the Xishan Coal Bureau to improve the process.

A large number of impurities of wrought iron, to use a hydraulic forging hammer, rich in impurities after heating, is thrown into the mortar, can not carry out complex precision machining hydraulic forging hammer, numb under the hydraulic force, constantly lift and fall, the impurities in the wrought iron forging, this step of the hydraulic forging hammer is because of rough but abundant and cheap power.

These wrought iron, which does not have many impurities, is heated again and burned to red, after two large steel rollers made of a roller press, this is because of the embossing of silver coins, Daming has more breakthroughs in rolling technology, after rolling, wrought iron without impurities has become a [wrought iron plate with uniform thickness].

The thin and uniform wrought iron plate was transferred from the hydraulic hammer workshop to the model workshop, and this step only needed to be molded, and then the craftsmen repaired the corners, and a [vain iron armor embryo] was done.

Wrought iron is soft in texture and extremely poor in strength, and no one can wear the armor of wrought iron, and Li Rusong, who is pulling out the mountains, wears iron armor made of wrought iron, and cannot fight.

As with hand-forging bright light armor, embryos with no appearance also need carburizing.

A piece of iron muddy nail embryos sprinkled with toner powder, thrown into the earth kiln, the earth kiln in the violent heating, began to close the kiln, this is the steel needle of the stewed steel method (Tiangong Kaiwu loaded), rows of iron muddy nail embryos in the high temperature closed without oxygen kiln, and the toner powder after full penetration, obtained [uniform carburization and good surface carburizing of the iron armor embryo].

At this point, the iron armor is still an embryo, it is still soft wrought iron, there is no defense at the same time, it is also very easy to deform, which needs to be quenched, quenching is divided into oil quenching and water quenching, under the violent thermal expansion and contraction, the embryo of the iron armor will be violently deformed, resulting in unusable.

The deformation problem needs to be solved, the embryo of the iron muddy armor is heated, and the iron brace will be put into the iron brace, and the red iron muddy armor embryo will enter the cold oil, under the violent thermal expansion and cold contraction, the iron will contract violently to form dense crystals, which is also the meaning of carburizing, the carbon atom can form a crystal nucleus in the process of shrinkage and crystallization, and the quenching strength of wrought iron will not be much improved.

[Wrought iron carburizing plate armor with initial defensive power] is ready, at this time, it still can't be worn, because the quenched iron armor has become hard, but it has also become brittle, and when facing a strong bow and fire gun of more than 100 catties, brittle is not an adjective but a fact like a piece of paper.

The next step is tempering, what to do is also very simple, put it into the clay kiln again, close the kiln without oxygen at high temperature, and after the dense crystals can be thawed slightly, you will get [uniform carburizing, good carburizing, good quenching and tempering correction of iron muddy armor].

In essence, this iron armor is still not steel, it is wrought iron, because the carbon content of each part of the iron armor is not the same, and the defense power is far inferior to the Mingguang armor made of pure steel, and the weight is greater.

If you want to get a steel plate with a uniform texture, the current Daming can only rely on the craftsmen of the strong nine clans to make it by hand.

This kind of iron armor is made in batches and cannot be tailor-made, so it is actually very unfitting, and there are certain difficulties in the use of soldiers, but in the ninth year of Wanli, it can be said very exactly: this is steel armor!

Not to mention the Beiyu, one-third of the Daming Jingying has such iron armor, and the defense power is already the limit of the current productivity.

The iron armor of the cavalry camp is a special half-body armor and cuirass, and the armor worn by Li Rusong is the same Mingguang armor as the Ming Emperor.

Wang Chonggu was the initiator of the "The World is Trapped in Mergers and Rescues Hooligans", and the profits of the woolen official factory led by him were also used to pay salaries to the Beijing camp, and the coal and steel joint venture of the Xishan Coal Bureau was responsible for manufacturing the armor, firearms, chariots and other armaments needed by the Ming Beijing camp.

Wang Chonggu is actively improving salt melting carburizing, and strive to make the mass production of the standard iron armor in terms of defense and weight, close to the emperor's Mingguang armor, which is very difficult, but in the past eight years, Wang Chonggu has been personally supervising the improvement of the process, compared with the original clanging forging, now the cost of the Ming iron armor has been reduced by half, which is the advantage of assembly line production, the defense power remains the same, the weight of a pair of full-body iron armor has been reduced from forty-four catties to thirty-seven catties.

The cavalry battalion led by Li Rusong is all equipped with iron hun half-body armor, each of whom has three war horses, and each war horse is carefully selected, the best of the best horses, and each war horse is fed with bean grain and forage, and it will not lose weight in winter, and everyone is equipped with firearms, handguns and riding guns.

Riding battalion, the real kryptonite warrior of the Ming Dynasty! The whole body is shining with eye-catching, real money!

The armor of the Central Plains is the same as the horses of the grassland, it is useless except for fighting, and the folk ban on armor, after the escape of the Northern Yuan Dynasty, the Northern Yuan Dynasty completely lost the craftsmen who returned to the Hui, and there was no stable supply of fuel and iron ore, coupled with the embargo policy of the Ming Dynasty since the Hongwu period, there are very few iron pots on the grassland, and the armor is even more pitiful.

After the peace of Longqing, there was indeed an iron pot in the grassland, but from the iron pot to the iron armor, do you expect the Beiyu to use cow dung to burn and forge?

So the steppe people are real flesh and blood, and it's good to have a pair of leather armor.

Dong Fox saw Li Rusong's figure through the clairvoyant mirror purchased with a lot of money, looked at the armor on Li Rusong's body and the good horse under him, and fell into two questions for a while.

The first question is: who is the prairie people! A cavalryman actually has three war horses, which are war horses, not horses!

The second question is: Is the trap you set really luring you into the urn, or is it a cocoon?

It wasn't until he saw Li Rusong and the cavalry camp he led with his own eyes that Dong Fox understood Chahannaoer's desperation and what kind of monster Chahannaoer was facing.

Dong Fox saw Li Rusong's figure, and Li Rusong also found the trap arranged by Dong Fox, and more than a dozen scouts galloped into the mountain col on the grassland, which is the mountain leading from Wuchuan to Bansheng City, called Wengguan Mountain, which is the only way.

It was impossible to observe the situation of this col from Li Rusongguan's position, but it was very, very easy to set up an ambush, and there were gentle slopes of hills on both sides, and once the enemy rushed down the gentle slope, Li Rusong and the twelve guards he brought with him would fall into a state of isolation.

"Major General, are we more cautious?" One of the guards had apparently observed the situation as well, and the dozen or so scouts were a bit like decoys.

Li Rusong reined in, nodded and said, "You're right. ”

Through the intelligence of the Marquis of Duntai, the person who came to commit the attack was Dong Fox, Dong Fox killed Tang Kekuan in Miyun, which was used to lure the enemy into depth, and Xu Da's defeat in the Battle of Lingbei was also because of the lone army, Li Rusong kept in mind what Qi Jiguang told him, the balance of victory will be tilted seventy percent if the striker wins, and if the striker loses, the army is defeated.

This position is so critical, his equipment is so good, he is crazy, not stupid.

"Dong Fox wants to deceive me and set up an ambush in this place, so I will plan and play tricks with him here." Li Rusong took more than a dozen guards and began to drive his horse forward, but he did not enter the disadvantaged terrain for a long time, so he was near the trap, circling around, constantly observing, and the more he observed, the more Li Rusong confirmed that an ambush was set up here.

When Dong Fox saw this scene, his heart was like a fox scratching, at this time it was time to compete for concentration, Li Rusong did not leave, he was still tempting, Dong Fox could only hold back the impatience in his heart in order to kill with one blow.

"Fooled!" Dong Fox was suddenly alert, because he heard the sound of horses' hooves, and the faint sound of horses' hooves made Dong Fox realize that this treacherous Li Rusong had already seen through his plan and deliberately stayed just to wait for reinforcements.

Dong Fox didn't think that he would be countered, but the rapid reaction and rapid maneuver that belonged to the grassland suddenly appeared on the Daming Army, so that he didn't react at all, and when the Daming Iron Horse appeared in the field of vision, Dong Fox knew that he had been tricked.

Daming's iron cavalry did not step into the trap, but chose to take a detour, Dong Fox ambushed two thousand people, completely exposed, an ambush turned into an encounter, Dong Fox suppressed the fear in his heart and began to command, just engaged in the battle, fell into a disadvantage.

The iron cavalry of the Ming Dynasty, the warriors of Jingtang, and the warriors of Krypton are swimming in the dragon.

To be exact, the Ming cavalry relied on the range and lethality of the firecracker, and did not intend to contact head-on, each cavalry battalion was too expensive, Li Rusong found the lethality of the 'queue shooting', chose long-range combat, three hundred years forward, this is the grassland trick, cavalry shooting, without contact, the biggest kill and wound the enemy, wait until the enemy's morale collapses, and then charge.

The grassland has not yet entered the rainy season, the smoke of gunpowder is permeated on the battlefield, the explosion of gunpowder is like a talisman, and every salvo will have countless grassland warriors blown out of pieces of blood by lead, and the arrows of the steppe people cannot hit the enemy at all.

Zhu Yijun practiced martial arts, he can't drive a 120-pound tiger bow now, but he can drive a strong bow of more than 100 catties, but when riding a horse, he can only use a 60-pound soft bow, Qi Jiguang said that riding and archery has little effect on the battlefield, because the battlefield environment has changed after the addition of firearms.

The recurve bow of the steppe people is sixty or seventy catties, and the effective killing range of the fire gun is much higher than that of the bow and arrow, and the cavalry battalion of the Ming Dynasty harvested the lives of the warriors under Dong Fox's tent in the volleys again and again.

Dong Fox began to order his sons to stare at the fire and charge, hoping to bite the enemy, but the horses under him were not all war horses, and after the harsh winter, because of the haze of war, the men and horses were all skinny, and they were not as good as the cavalry of the cavalry battalion in terms of explosive power or endurance.

Unconsciously, Dong Fox didn't notice that the battlefield had undergone some shifts, and the two hilly cols had changed from the Ming army's impact on the enemy's position to the enemy's attack on the hill where the Ming army was located.

"Artillery!" Dong Fox's eyes are about to split!

If you can't afford it, don't play!

A good cavalry hedge, you put an artillery array on the tip of the hill is a few meanings!

This Li Rusong doesn't talk about martial arts, and actually pulled the chariot to the hills!

In the half-hour confrontation, Li Rusong completed the artillery arrangement, and the initiative on the battlefield had already been quietly transferred to Li Rusong's hands.

"Retreat! Withdraw! Withdraw! ”

Dong Fox stood under the big sword and gave a loud order, but it was completely too late, because the smoke of the artillery had already risen, and the roar came after a short while.

A total of forty-five nine-pound artillery guns fired the first salvo, and forty-five flowering shells crossed the sky, reflecting the sunset at dusk, and suddenly exploded when they approached the ground.

The steppe cavalry without armor, in the face of artillery, especially flowering shells, only flesh and blood, did not have any resistance at all, and many people died, most of them were injured, whether it was a human or a horse wounded, it was fatal on the battlefield.

"Retreat! Fall back! Dong Fox finally understood Li Rusong's toughness, the whole person was like a crazy demon, shouting loudly to command, after he ordered the retreat, he began to flee with his house slaves.

Li Rusong picked up his mace, drove the horse forward slowly, and shouted loudly: "Daming cavalry battalion, charge!" ”

The tooth flag began to wave, the cavalry began to gather behind Li Rusong, the cavalry camp was walking slowly at first, after more than a dozen steps, it became a fast step, and after more than 20 steps, it became a galloping horse, Li Rusong took the lead, leading the cavalry battalion to start charging towards the enemy under the hills, the horseshoe under the horse's hooves trampled the grass, trampled on the gravel, and the steel torrent like the cavalry battalion swooped down from the top of the hill.

Li Rusong is a madman on the battlefield, the weapon he uses is a mace, every time he wields it, it will bring out a puff of blood mist, and the two hundred guards he led are like a sharp knife to completely tear apart the enemy formation, and then the personal soldiers are divided into two and tore left and right, and Dong Fox's department immediately fell into a complete disadvantage.

After two rounds of charges, the rout began, with the heavily armored cavalry battalions not pursuing, while the cuirassiers on both sides began to pursue.

Cuirassiers are cavalry with only cuirass, not even a half-body armor, the main force is a mobile force, responsible for maneuvering support and pursuit on the battlefield, and heavy cavalry is mainly used to break the formation and chisel through the enemy's line, resulting in the enemy's rout.

Li Rusong had completely mastered the operation of the cavalry battalion, and after the light cavalry repeatedly harassed and shot the enemy to cause the enemy's exhaustion, the heavy cavalry made a final decision, and the light cavalry began a long safari and pursuit.

The only heavy cavalry figure in the light cavalry is Li Rusong himself, his armor is very light only twenty-five catties, his horses are very strong, he has three horses, one horse is called Feiyi, one horse is named Shengjian, and one is called Zhaoxue, the first two are the royal horses given to His Majesty by Shah Mamaiti (Chapter 350), Zhu Yijun gave these two national gifts to Li Rusong.

The flying wings run fast, the winning sword is extremely fierce, and Zhaoxue was given to Li Rusong by Qi Jiguang, the biggest advantage of this horse is endurance, which was given by Qi Jiguang to Li Rusong to escape, endurance is the most important in escape, Li Rusong did not use Zhaoxue for escape, but for chasing.

Two days later, Dong Fox and the remnants of the defeated army of about 300 people rested in the leeward part of the grassland, and he didn't know where he was.

His headquarters was originally a team of 10,000 people, after repeated conflicts, when he defected to Altan Khan, there were only 5,000 people left, he took out 2,000 people to ambush Li Rusong, but was eaten by Li Rusong, after he fled back to the camp, thought that Li Rusong would not chase over, but the Ming cavalry camp only took half a day, and it was assembled, after dawn, the Ming cavalry camp, began to attack his camp.

The camp built by Dong Fox was completely breached before it lasted two hours, and Dong Fox began to flee with 2,000 people, and it was another day and night, and there were less than 300 people left around him.

"Crazy, really crazy!" Dong Fox said sharply with red eyes, in the past two days and two nights, Li Rusong's tooth flag has always been fluttering at the front, Dong Fox didn't think about rushing to kill, and directly killed the opponent's main general, but every time he was backwashed back by Li Rusong.

"I regret that I shouldn't have killed Tang Kekuan." Dong Fox was lying on the grassland, those plants and trees were like enemies, so he couldn't sleep, and remorse was clouded again, regret had been said countless times, but there was no regret medicine to take.

Da Ming is very resentful, won a one-time pass, when who led how many people and where to win the enemy, what kind of exploits to get, lost, that is, can not be written, Da Ming's pen began their own performance, analysis of why they lost, how to win back, how much scale of the enemy, the analysis of the sparse arguments, written in the historical records is also a long story.

If you win, you should have lost, and if you lose, you should write it down in a small book.

Dong Fox really didn't close his eyes for two days and two nights, he kept running, Li Rusong slept for two hours and one hour, he was not iron, before going to bed, he would make a bowl of fried flour, pour water and stir it casually and pour it directly into his mouth, gnaw a light cake, and drink a bag of water.

The reason why Li Rusong wanted to chase Dong Fox was that he refused to let go for two days and two nights, and he continued to pursue. is because Qi Jiguang once mentioned his guilt towards Tang Kekuan.

Tang Kekuan's death was because he did not follow Qi Jiguang's general order and died by attacking himself, but Qi Jiguang felt that he had his own reasons, he was a general and commanded a large corps to fight, and he should have taken into account the complexity of the battlefield.

Tang Kekuan died, his son could not inherit Tang Kekuan's hereditary command Tongzhi (Zheng Sipin military attaché) became white, Qi Jiguang thought that if he had the opportunity, he must kill Dong Fox, so that Tang Kekuan's children and grandchildren could continue to hereditary command Tongzhi, and they could receive their sons and daughters without leading troops.

Li Rusong has an opportunity, so he naturally won't miss it.

The trace of Dong Fox was found, Li Rusong set off again, it was not far, less than ten miles, it only took a quarter of an hour, Li Rusong found Dong Fox, the completely tired Dong Fox was fighting with his eyelids, and he heard the sound of horses' hooves.

The sound of horses' hooves came from all directions, and he was surrounded.

"Dong Fox! Surrender willingly! Li Rusong's angry shouts sounded a hundred steps away, and the arrows poured into the circle formed by Dong Fox's three hundred people.

Dong Fox and his remaining 300 men had no combat ability or will to resist at all, and after two quarters of an hour, they were either killed or captured.

Dong Fox lay on the ground panting, followed the mace in front of him, looked up at Li Rusong on the horse, but showed a relaxed and relieved look, he was tired, really tired, this madman couldn't get rid of it at all, but he could live a stable life for a month or two when he was captured, and the escort Jingshi would be beheaded, but if he continued to run, his subordinates would definitely cut off his head as a vote of nomination, and surrender to Daming in exchange for a reward.

Hit, can't beat, run, can't run.

Li Rusong's battle of Weng Guan Mountain, completely annihilated more than 5,000 people under Dong Fox, killed more than 4,300 enemies, and the number of dead in the cavalry battalion was only 17 people.

The defeat of Bansheng City is even more serious than before, Altan Khan's 50,000 households, 50,000 deserters exceeded nearly 5,000, and the morale has completely fallen to the bottom, Qi Jiguang led the troops of the headquarters has come to Bansheng City ten miles away to camp, and the army began to besiege the city.

Altan Khan did not go out of the city for a decisive battle, because the cavalry battalion led by Li Rusong was still stationed in Wuchuan, and once he left the city, he would be at a disadvantage of being flanked from the front and back.

Qi Jiguang did not order the siege of the city, but began to declare that the head of Altan Khan was worth 1,000 taels, the head of 10,000 households was 500 taels, and the head of 1,000 households was 100 taels.

Qi Jiguang was not a threat, he put the artillery out in turn and began to bombard three times a day.

On the third day, the city wall of Bansheng has been completely destroyed, and under the pouring of nearly 10,000 artillery pieces and 500,000 catties of gunpowder that came to Beijing this time, Bansheng is a city that does not surround 30 miles, and it cannot bear such artillery coverage at all.

Qi Jiguang is not a squander, but also a helpless move, the gunpowder must be pulled out, otherwise it will deteriorate when the rainy season is reached, the grassland is not the Central Plains, and there are not such good preservation conditions.

Moreover, the supply pulled another 100,000 catties of gunpowder to the front line, and 500,000 catties of gunpowder went down, and Bansheng City could no longer be called a city.

On this day, Qi Jiguang came to the front line, and ten cannons that were more than two feet long and had stomachs like buckets appeared outside Bansheng City, which was a thirty-pound cannon made out by the Royal Gewu Academy.

It is said that it is a naval gun to be used on the Youlong, and the largest artillery of the Ming Dynasty is fifteen catties of gunpowder, and these thirty catties of artillery are really beyond everyone's expectations.

Land warfare, this thing can only defend the city, and it doesn't mean much, but in naval warfare, this thing is extremely useful.

It is said that the madmen of the Royal Gewu Institute are going to get another fifty-pound cannon, these thirty-pound artillery has been test-fired many times, and this time it was pulled to the grassland to test the reliability of the equipment, whether it can be fired smoothly after a long bump, and the ammunition fired is not a flowering bullet, but a solid sub-munition.

So ten cannons were pulled to the bottom of Bansheng City, and Buyan Taiji, who was in charge of the lookout, slowly raised a '? 'Come on.

Altan Khan how can he be, how can Bansheng City do he, do you use this thing?

Qi Shuai, use the clairvoyant mirror to look at the city wall that has completely collapsed!

After the fuse was ignited, everyone retreated a hundred steps away, if this thing exploded, it was not a joke, Qi Jiguang had seen this thing explode with his own eyes, and the endless roar sounded outside the city of Bansheng, like thunder, the heavens and the earth were trembling, and the bullet was under the roar, like a black horse, pounced on the only remaining city gate, smashed through the city gate building, and smashed into the city.

Ten 30-pound guns killed 0 enemies.

"It's a waste." Chen Dacheng looked at this scene sluggishly, of course the big fireworks are beautiful and scary, but three hundred catties of gunpowder = 15,000 flintlock guns, how can it kill two people, this thing seems to be useless except for completely smashing the already dilapidated city gate.

In fact, it is useful to break morale.

In the afternoon, Altan Khan sent his second son, Buyan Taiji, to the Ming camp to discuss surrender.

These ten thirty-pound artillery pieces are the confidence, Daming has gunpowder, Altan Khan finally chose to surrender, Qi Jiguang built the camp fort to the city of Bansheng, he is already cornered.
