When he arrived at the south gate, King Jin had been waiting for a long time in Dianjiangtai to practice for Wang Shuo. Wang Shuo jumped down from his horse and stepped forward to salute:

"Minister Wang Shuo, meet the king!"

"General Wang is exempt. This wine is practiced for the general, and the widow wishes General Wang victory in the first battle and the prestige of our army! ”

Wang Shuo took the wine bottle and said generously:

"Thank you for the wine, the ministers should live up to the king's trust, kill the enemy to serve the country, and strengthen our army!"

Wang Shuo drank it all, and King Jin was happy.

At this time, in the dark, Uncle Kuo sat on a wicker chair, and was carried by four strong men to the Dianjiangtai, although he was blind and dying. But at the last moment of the battle, Uncle Kuo was still relieved, and he couldn't help but have a few words of advice:

"General Wang Shuo......"

Uncle Kuo was as weak as a candle in the wind, Wang Shuo cautiously stepped forward to listen:

"The last general, what do you command?"

"Let's go...... To go to the Xian, entrusting you with the post of Sima envoy is really an old man's protection, and the most important thing is that the general is cautious and careful. Therefore, in this battle, the general must take every step of the way, and not be in a hurry. The eastern land and water network of the eastern part of the country is vertical and horizontal, and it is connected to the north of our country, and the general must guard the back, and do not let it take advantage of the weakness. ”

"Remember!"

"In addition, the old man knows that our naval army is powerful and the warships are excellent, but the soldiers are still lacking in tempering, so the naval army is also under the control of the northern army this time, and the fighter cannot be engaged if there is no fighter, and the morale of the salty navy can only be fought when the morale of the salty navy is exhausted."

"Please rest assured that the last general will not disgrace the trust of Xiangguo!"

When Wang Shuo was talking to Xiangguo, the third son of the King of Jin, Ji Chang, rode a horse and blocked Bailiyan's way:

"Everyone in the market hears that Gongzi Yan is as timid as a mouse, why is he in battle with the army this time!"

Ji Changyan said sarcastically, but Bai Liyan said:

"Could it be that the blood of the people is not blood, or only the prince of Chang is the eldest husband in the Jin Kingdom, and the others are all rats."

"You!" Ji Chang is angry and fried his liver and lungs, this is a turning and scolding Jin people are all rats.

While the two were arguing, Medical Officer Xu quietly came:

"Young Master Yan."

Baili Yan jumped down and stepped forward and said:

"Doctor Xu, do you have any advice?"

"Hearing the news that Yan Gongzi is with the army, the old man is very worried about Xiangguo."

"I'll take a step to speak."

When he came to no man's land with Medical Officer Xu, Bai Liyan said:

"Doctor Xu, Xiangguo's illness is only an image of returning to the light, not a long-term phenomenon. After this son goes, the medical officer Xu must decoction according to the medicine, and it cannot be interrupted, and the medicine will be self-destructive and cannot be continued. ”

"The old man must remember the son's entrustment, this time the son goes on the expedition, be sure to be careful."

Doctor Xu had something to say, and Baili Yan understood it. As the imperial medical officer of the King of Jin, of course Medical Officer Xu can hear the rumors, but out of the doctor's professional ethics and his own head, he can't say it clearly.

Thinking of this, Baili Yan had an idea, and said to Doctor Xu:

"Doctor Xu, this son has not yet informed the Proton Mansion of his expedition. If it is convenient, please speak to He Kuan, the steward of the Proton Mansion, on behalf of this son, and say that this son has gone north, and let him decide all the affairs of the house on his own. ”

"I'm afraid this is inappropriate...... "Medical Officer Xu worried.

"Naturally, you can't do it before the war, but you can do it after the war, Doctor Xu understands?"

Medical Officer Xu suddenly realized:

"The old man understands, and the old man must bring the words."

"Then there's the need for the medical officer to bother."

Most of the profession of a doctor is a profession of conscience, and Baili Yan is sure that the medical officer will definitely bring the words.

He has been under house arrest for more than a month, and the dragons in the house have no leader, He Kuan has no instructions from himself, and he does not dare to help him. Bai Liyan asked Medical Officer Xu to speak, and there was no problem with it, but only He Kuan knew what it meant.

Just after Bai Liyan and Doctor Xu talked for a while, the south gate was wide open, and Wang Shuo was full of spirits and led more than 1,000 horsemen out of the city. Baili Yan rode his horse to follow and asked Wang Shuo:

"Father-in-law, why did the army only accompany more than a thousand horsemen when it went into battle?"

"This time I went north, I was lightly armed and simple, so I went out of the city for more than 30 miles to the north, and we will join the cavalry vanguard, and then continue to go north to meet the cavalry from all over the country one by one."

"I see!"

Bailiyan suddenly realized that Wang Shuo's army was cavalry this time, and on the way north, the formed cavalry from all over the country quickly assembled along the way, according to this, the number of cavalry led by Wang Shuo would not be less than 40,000, plus the cavalry of the Northern Army of the Jin Kingdom, I don't know how many.

At present, there is a strange thing, and the military guiding ideology of the Spring and Autumn Period and the Warring States Period of Qin's unification of China is different, the current cavalry resources are quite abundant, and the plateau grassland is in the south, the major vassal states have their own vast grasslands to raise horses, and the north is the middle temperate zone, sub-heat, tropical warm and humid plains, rich in products.

The entire Central Plains continental plate is located in the southern hemisphere of the planet, thanks to the vast grassland, huge territory, and the relative size of the population base, the current light cavalry is very developed, the more developed cavalry quickly eliminated the more rigid chariots, and the development of infantry tactics and combat equipment has greatly weakened the role of chariots.

In addition, the current development of war horse equipment is relatively advanced, and saddles, horse bridges, and stirrups have appeared.

Before the appearance of the stirrup, the cavalry could only rely on the legs to clamp the horse's belly to prevent falling during the attack, so the advantage of the chariot soldiers at that time was more obvious, and after the stirrup, the feet were fixed in the stirrup, which liberated the legs of the person to the greatest extent, and the flexibility and comfort of maneuver were far better than the chariot.

Ancient China was invented in the Western Han Dynasty, when iron tools had been fully popularized, and Europe did not find that the cavalry still had horse bridges and stirrups until the invasion of the Xiongnu.

Subject to the constraints of current metallurgy and processing technology, stirrups are mainly a kind of ring-shaped stirrups woven with coarse linen, which is moderately hard, cheap and easy to equip generally, and is undoubtedly more suitable for large-scale equipment than expensive bronze and more refined iron.

But in this way, it restricts the development of light cavalry to heavy cavalry, heavy cavalry is restricted by the weight of the equipment, the impact inertia is great, and the strength of the stirrups made of coarse linen is not enough to support the inertial impact of the human body after the weight and is very easy to break.

Therefore, the cavalry is still dominated by light cavalry, and there are very few heavy cavalry equipped with metal vests. Metal stirrups and vests were mostly only used for the elite, or even a status symbol for the privileged.

In addition, the current agricultural productivity is low, and in addition to raising horses, they need forage, and after raising horses in the army and running long distances, horses also need to be fed some grain concentrate rations.

Take eating grass as an example, if the horse eats grass, it takes more than 12 hours a day to eat grass, of course, this time is not an absolute value, affected by factors such as horse food, exercise status, horse breed, grass situation, season, etc., the time for horses to eat is not the same, if you change to eat grain and forage mixture, you don't need half, that is, half a night, the energy and satiety of the two, grain has more advantages than forage.

At the same time, grain-fed horses tend to gain weight, while forage-fed horses need a quarter to recover the fat that fell during combat. Therefore, the war horses of the great powers are partly raised in the grassland, and partly in the army.

Those raised in the grasslands are fed with grazing, while those raised in the Central Plains are mixed with grain and grass to reduce food consumption and meet the needs of warfare at the same time.

In addition to the Jin Dynasty, there were large horse farms in the Xu and Song kingdoms, and there were also horse farms in the south of Wei and Zhi. Although the territory of the Song State is large, the population is small, the grain production is low, and it is located on the plateau, there is a serious shortage of salt, coal, copper, tin, and iron, and almost all of them rely on the input of the neighboring Zhiguo and the Jin State, so although the Song State has a land area far exceeding the Jin State, the national strength is very weak, and it is also the reason why the Song State pays tribute to the Jin State.

In addition, at present, all the classics, there is no reference to the situation of the nomadic people, Xu and Song are located in the same grassland, because of the abundant water sources, the large rivers are very large, so they are still mainly engaged in farming and planting wheat and soybeans, there is no nomadic habit, but the agricultural production system of grazing has been formed.

This means that the southern plateau is either extremely high in altitude and inaccessible in oxygen, or the migration of ethnic groups has always been controlled by the central dynasty, and there is no special history of the population of the Xia Dynasty in China moving north and losing contact, and finally developing into the Xiongnu.

In this way, the princes of the Central Plains always firmly controlled the horse-producing areas, and the source of horses was greatly guaranteed, so the cavalry battles were more frequent, and the light cavalry was the mainstay, and there was almost no development of heavy cavalry. Among them, the development of productivity and technology limited the development of heavy cavalry, which in turn stimulated the infantry to develop a large number of restraint cavalry tactics.
