After three days, Gao Pang designed the plan and facilities of the lead and zinc plant, and asked Fu Bo to prepare separately, and the construction of several factories of his grandfather has been carried out separately in Tongling.

In addition to training martial arts, the predecessor of Gao Pet's reality also studied the art of war, but he still didn't know much about the battle formation and combat methods of this era. If we don't understand these things, we can't say that we understand the enemy and know each other and ourselves. Many of the battle formations were absolutely top-secret techniques at that time, passed down from master to apprentice, and even Guan Yu and a few people who had learned from home could not say clearly. He went to find his second uncle, and also his grandfather and second uncle. Although several of them have experienced it, the critical knowledge is still insufficient. Fortunately, the second uncle remembered that there was a herb of Gao's "Gao's Art of War" and related information in the library of the ancestral hall, saying that in his later years, Gao Zu wanted to pass on his combat experience, collected a lot of information, and also got a lot of battle formations of various art of war, but in the end, he didn't expect that he died so quickly, and he didn't write a book, so he went and only lived to be 56 years old.

According to the information in his hand and some of his own memories, Gao Pet spent a considerable amount of time sorting it out.

The main combat force of the Southern Song Dynasty was cavalry, and the cavalry was divided into heavy cavalry and light cavalry. Heavy cavalry such as the Tiefutu of the Jin Kingdom is the core force of the Jin Kingdom that cannot be moved lightly, with strong offensive and defensive capabilities, and its heavy armor can resist general bow and arrow attacks. The light cavalry has strong mobility and offensive power.

As for the current cavalry battle formation of the Jin State, the two wings are generally equipped with light cavalry, which are responsible for attacking and harassing the weak flanks of the enemy formation, and shaking the enemy's own formation by chaotic enemy formation or centripetal attack with two wings. In particular, the archers in the light cavalry mainly focused on harassment and attack, and also often used the tactics of shooting at close range.

Cavalry is the most powerful force in the field. One of his strengths is the shock power of the cavalry, and the other is the speed and mobility of the cavalry's attack. If the cavalry does not fight against the infantry, it will basically not lose, and the initiative is in the hands of the cavalry. Gao Zhong does not have cavalry yet, so how to fight against cavalry has always been Gao Chong's most concerned issue.

Infantry, with archers as the main force, archers are long-range attack troops, archers and crossbowmen two types of archers. Archers use bows with more than 1.5 stones, which is a pulling force of 90 kilograms, which are super archers, which are very rare, so the average archer is only 0.8 stones, that is, about 50 kilograms. Generally, except for the first arrow, it is rare to fill the bow, and it is even more impossible to fill the bow in the face of rapid fire when facing the enemy's charge, and it is generally only six or seven points. Generally, the maximum range of the bow is only 240 to 350 meters, and the flat fire can only be about 75 to 120 meters due to the presence of Wangshan. More than 120 meters are all strong bows and super shooters. But Song Ji had almost no record of throwing bows and arrows before, and only after asking a few seniors did he know that the projectile that Gao Zhong said must be there, and the first round of arrows can only be thrown a hundred paces away.

The Song Dynasty's standard Shenjian crossbow had a bow power of between 3 and 4 stones, and because the crossbow arrows were short and thick, and the mass of the arrows was between 30 and 40 grams in modern times, the projectile could shoot up to about 300 to 480 meters, and the farthest direct shot was about 100 to 160 meters. The historical record of the longest 300 paces and the general 240 paces with the Divine Arm Bow is credible. But to pull 4 stones and 480 catties, they are all the top combat power. Only in the forbidden army. Infantry is generally equipped with a crossbow of only two to three stones, and because the arrows are lighter, they can shoot up to about 300 to 400 meters. Direct radiation is up to about 100 meters to 135 meters.

The infantry battle formation is generally 3 rows of spearmen in the front row, and the archers in the rear are arranged one by one according to the firing range. Archers accounted for more than fifty percent. This is also the arrangement of the main battle formations of the Song soldiers against the cavalry. Therefore, ordinary people can have knives and guns, but they can never have bows and arrows.

Against cavalry, the first three rounds of the bow and arrow are very important, the bow and arrow are faster than the crossbow arrow, but it is difficult to last, the range is also short, the strength of the warrior is very demanding, and it takes a long time to train. And the crossbowmen have a slow rate of fire, and even ordinary soldiers can do it. Fast learning, long range, high shooting accuracy.

In order to defend against the flanking attacks of the abducted horses (light riders on both wings), geese were also often arranged in formations, or special defensive queues were arranged.

The other spearmen and sword and shield soldiers are auxiliary troops. It's all melee defense-based.

In the field, there were many ways to defend the cavalry attack, and a full infantry phalanx against the cavalry was the most effective method at the time. Including the chariot formation, such as the iron pulley, is the equipment of the cavalry attack on both sides. In "Saying Yue" and many dramas, Gao Pet picked eleven iron sheaves at that time, each weighing about 1,000 catties, one is to illustrate the strength of Gao Pet, and the other is to show that in the face of the powerful attack of the cavalry, the iron pulley is a more effective obstacle tactic.

There are three main ways for infantry to fight cavalry, one is to form a formation, the second is to attack with long-range bows and arrows, and the third is to hinder the speed of cavalry with obstacle tactics. In fact, the best way to break the cavalry is to defeat the cavalry with cavalry.

Infantry against cavalry is a weak branch of the army in the era of cold weapons, especially in field battles, there is no encounter before the formation, how to delay the attack of the enemy cavalry and quickly form a formation, has always been a research topic for soldiers.

But in any case, because the mobility of cavalry is much higher than that of infantry, infantry can only be passively defended in wartime, and cannot be organized into an effective attack. In particular, logistical or small units are the most vulnerable to cavalry extermination.

Through research, Gao Zhong knew that the abducted horse was a two-winged cavalry, the iron float was just a heavy horse of the golden vulture, and the iron pulley was just a heavy iron chariot to defend the cavalry array. It is not as mysterious as Yue Ke's "Chronicle of King E" said: "Wushu has a strong army, all of which are heavily sold, running through Wei Suo (leather rope), where the three people are linked, the number of abduction horses, and the number of iron floats, blocking the wall and entering, the officers and soldiers can not be, so they have won many victories." "Just like Yue Fei's grandson Yue Ke, it has only been a few decades in the past, and so many fundamental mistakes have been made. If Gu Tian hadn't come to this Great Song Dynasty and asked a lot of people, he really didn't know what was going on, would Yue Fei's grandson be wrong?

While studying the characteristics of each army at that time, Gao Zhong trained his teaching team, improved his training direction, adjusted the composition of his original plan and the combination of troops, and sometimes called Second Uncle, Guan Yu, Stilwell, and others to discuss together. Sometimes I look at the progress of several factories under construction and solve some problems on the site, and many days have passed like this. Until my grandfather informed them that the coke factory was going to open on fire.

Due to the intense training of the teaching team, this time it opened, and Gao Pet also brought Guan Yu, Stilwell Dazhu and a few guards. Of course, Guan Lin is indispensable, in order to participate in this opening ceremony, Guan Lin was very busy for a while, nothing else, buying clothes, dressing up, and finally taking off the military uniform, not to mention anything else, just Guan Lin's figure, wearing a military uniform is really very tempting, often makes people look at the heart ripples, sometimes Gao Zhong really doubts whether he has uniform control.

The time of opening is the hour, but the high pet came early in the morning, although the first day to check it carefully, but the heart is not at ease, so it comes early, it doesn't matter if the high pet is early, but it hurts, you see our big beauty, in the Yin time to get up. After a long time, when he came out, Guan Lin stood in front of Gao Chong and asked Gao Chong: "Gao Chong, what do you think of this dress?" ”

Gao Pet just broke free from the youthful and energetic uniform control, and what came to his face was a lively and cheerful fresh breath, Gao Pet really wanted to push down the one in front of him, and ate it in one bite. Push over? I'm only fourteen years old, how can I have so many strange thoughts in my heart?

"Our Linlin is getting prettier and prettier. Okay, let's go. ”

The coking plant is designed according to the improvement of modern coke plants, and the distillation of tar oil and gas is recovered, and the gas produced is returned to the combustion chamber to be fully utilized. Tar is a treasure, although it is not used much by high pets now. However, Gao Chong also built a small distillation tower in the factory to divide light oil, phenol, naphthalene and heavy tar. This heavy tar is ready to be used as a crucible. In addition, a tank was added to recover hydrogen cyanide from the exhaust gas and to make dyes yellow blood salt, Prussian blue and teng blue.

The coke kiln is built along the hillside, with a fire tunnel in the middle and closed coke chambers on both sides, each of which is connected to a pipe. This is also thanks to the second uncle's idea of using ceramic pipes, and if you use iron pipes, I don't know that year you can use them.

Grandpa and they also arrived early, and when they saw the arrival of Gao Zhong and his party, they hurriedly greeted him, and a label by the factory gate was now covered with red silk cloth. There are two factory guards standing upright on the side, very energetic. Flowers and plants were also placed on both sides of the door, and I heard that it was also the idea of Gao Pet, for this opening, Gao Pet let the gunpowder factory also specially arrange to make a lot of artillery battles and firecrackers.

The second uncle greeted the congratulatory guests at the door, and the grandfather and the housekeeper of the factory personally accompanied Gao Pet to check all aspects again. Guan Yu and Stilwell followed behind, seeing all this was very novel, the most pitiful was Guan Lin, the beautiful clothes seemed to be in vain. After a circle, more than an hour passed, and the guests arrived one after another. When I arrived at the reception room, I saw that my mother, second uncle and second brother had arrived, as well as my little cousin, Su Huilan, the daughter of my second uncle.

"Cousin." Seeing Gao Pet come in, Cousin Huilan exclaimed in surprise. Immediately got up and ran over to hang on Gao Pet's arm.

"I haven't seen my cousin in days!"

Gao Pet was talking to his cousin, and the concierge at the door called:

"The county lord has arrived!"

Gao Pet and a group of guests immediately greeted him out.

"Congratulations, congratulations, Master Su, the student is polite."

"Han Bing, come and see Uncle Su." Behind Luo Xianling, a twelve or thirteen little woman turned out, dignified and beautiful, wearing a set of pink Luo skirts. Luoluo generously said a blessing to Master Su: "Good old man! ”。

The county lord Luo Zhen saw Gao Pet here.

"Isn't this the eldest son of the Gao family, Gao Favorite nephew, Han Bing, I've seen Gao Gongzi, how close you young people are."

"Hello Mr. Gao!"

"Luo Xiaomei is good!"

Not to mention that Master Su and the county master greeted each other, Gao Zhong introduced Luo Hanbing to the Guan Yu brothers and sisters and a group of brothers, and everyone was talking and waiting for the ceremony to begin. This Luo Hanbing was not born, and he talked and laughed with Guan Lin and Su Huilan after a while.

When the time came, Mrs. Su and Mr. Luo took down the red banner of the label in the sound of firecrackers. What you see is:

"China Huanyu Company Tongling Coke Plant" gilt bronze medal.
