After the Qin State obtained the stirrup, it quickly formed a cavalry advantage over the Chu State and the Kwantung States, which had been expected before. Just as any innovation from a small company in the future will ultimately benefit a large company, this is a helpless thing. If there are no stirrups in the Qin State, there are still martial knights, and if there are no stirrups in the Chu State, they will be pressed and beaten by the martial knights of the Qin State.

The number of dragon horses is too scarce, and the time to get is too late, to apply the age of the Central Plains countries, Xiong Jing seven years of dragon horses all arrived on Yangma Island, that year only gave birth to more than 400 foals, eight years, nine years to barely give birth to a thousand horses. According to the exchange ratio of one to four, if you want to deal with the four to fifty thousand warriors of the Qin State, you need at least 10,000 dragon horses.

Knights and horses are precious to the Chu State, and knights must be cultivated from an early age - now the sons and daughters of the nobles and scholars are all sent to Yangma Island, and they can only go out of Yangma Island in four or five years before they can become knights, and it will take another four or five years for them to become real knights.

However, for the Qin State, the cavalry is not more expensive than the infantry, Beidi County, Shangjun, as well as Jiuyuan and Yunzhong County before the Zhao State, there are countless riders, these people do not need to be painstakingly cultivated for ten years, they can be conquered at any time, their riding skills are not inferior to the noble knights painstakingly cultivated by the Chu State. Not to mention horses, as long as the Qin State pays enough compensation, the war horse will never become a bottleneck, and several times the number of horses is the bottleneck.

War is also a kind of trade in many cases, and there is also an absolute trade advantage. That is, in the production of a certain arm (commodity), the labor cost of one country is absolutely lower than the advantage of another country in the production of that arm (commodity).

This advantage comes from favorable natural endowments or acquired favorable conditions. Natural endowments and acquired conditions vary from country to country, which provides the basis for the international division of labour. Therefore, all countries should follow the principle of international division of labor and carry out wars (international trade) on the basis of the international division of labor, so as to form a sphere of influence corresponding to the superiority of each country's arms (commodities).

From this point of view, including the entire Fangcheng, the north of the Huai River in the Qinling Mountains should be abandoned. The Chu state had the advantage of boat divisions and mountain infantry rather than chariot cavalry, but the north of the Huai River in the Qinling Mountains was precisely a densely populated area. The result of abandoning this area is the loss of more than 70 per cent of the population.

Migration is impossible, and the area south of the Yangtze River can migrate at most 600,000 to 700,000 households, 300 to 3.5 million people. If you want to keep this large part of the population, you have to fight hard with the Qin State north of the Qinhuai line with the Qin State at a very high cost. Before the number of dragoons reached 10,000 five years later, the Chu state had no advantage.

The courtiers who understand know the stakes, but the courtiers who don't understand don't dare to talk nonsense anymore, and no one in the Ming Hall spoke for a while. Xiong Jing seemed to be able to see that in the spring, groups of Qin cavalry swept around with their swords raised, killing farmers who were sowing seeds in the fields; When the corn is ripe in autumn, they will burn the golden seedlings everywhere with a fire. Cavalry is a type of military with the advantage of tactical mobility, and it is normal to attack and harass three or four hundred miles deep into the enemy's territory, and these three or four hundred miles are the grain-producing areas of the three kingdoms of Chu, Wei, and Qi.

"Bashu," Xiong Jing stood up, and two temple people on one side were pulling a large map. His hand clapped on the position of Shu Kingdom, and said very resolutely: "I must take it this year!" ”

His words The ministers nodded, pulling out Qin Hanzhong and Bashu is the established strategy of the Great Sima Mansion this year, but the previous emphasis was on Qin Hanzhong rather than Bashu. Pulling out the Qin and Hanzhong dynasties, echoing the Huangzhong Qiang people west of Longxi County, the Chu army could attack and occupy Longxi County of Qin.

The Zhou had the ancestors of the Qin people move to Xiinuqiu (near today's Shuishi) as a migratory suppression strategy. Environment, or more colloquially speaking, the ass is everything. If the surname Win is in Qidi, they are the enemies of the Zhou people, and if they migrate to Longxi, they are the most loyal allies of the Zhou people. If they don't rely on the Zhou people to fight against the Rong people, they will be swallowed up by the Rong people. Several generations of ancestors of the Qin State died on the battlefield and swept away Xirong before they were allowed to build a city in Qin (now Qinting, Qingshui County).

Ji County, which is the closest to Lingzun Mountain, is the land obtained by Qin Wugong in the tenth year (688 years ago). The Qiang people were also driven away by the Qin people several times, and they knew the place where the Rong people lived by listening to the names of these places. Not to mention the ancestral relatives of the Qiang people and the Chu people, in line with the principle that the enemy of the enemy is an ally, the Chu State also wants to fund the Qiang people and let them make trouble in Longxi.

"We must pull out the Hanzhong of Qin, and ally with the Qiang people to help them seize Longxi." Xiong Jing pointed to Huangshui again, which was also the plan of the Great Sima Mansion.

"Not at all!" An unexpected person spoke up. "I thought this plan would not work."

"Why not?" Xiong Jing looked at Shi Yan puzzled, he couldn't understand why he was opposed.

"If I am in alliance with the Qiang people, the Qin people will also be beneficial." Shi Yan said. "Does the king know the widow?"

"Yes." Xiong Jing nodded, he also knew that the mercury in the tomb of Qin Shi Huang was all provided by the widow Qing.

"Do you know how much sake is worth?" Si Hui asked again.

"A bell? Qi Zhong or Wei Zhong? Xiong Jing didn't understand whether Shi Yan was asking Qi Guozhong or Wei Guozhong. If it is the Qi State Bell, it is ten stones, and if it is the Wei State Bell, it is only six stones and four buckets.

After the completion of the Zhengguo Canal, the fields that can be irrigated will be harvested for one minute. Qin mu is a large mu, which is equal to two .5 small mu. A small mu of Shangtian encounters a good year with a yield of two stones and seven buckets, which is converted into Qin mu, that is, six stones, seven buckets and five liters. This is the yield that only exists in Ueda's harvest years, and if it is a normal year or a small year, it is only about six koku.

"Naturally, it is the bell of the Wei Kingdom." Shi Yan said.

"If it's the bell of the Wei Kingdom," Xiong Jing remembered the price of sake mentioned in the palace library the previous time, and said, "It's only five or six hundred yuan." ”

"The world knows that the Qin people suppress the business and the poor, and the poor are considered to be the recipients, but the widow Qing is the great merchant of Qin, and its ancestors have the Dan cave, and they are good at this for several generations, and the family is not cheap, and the rich can rival the country, and the king of Qin built a daughter for the Qing platform; Wu's animal husbandry, and the king of Rong to buy and sell, its horses and cattle measured in the valley, the king of Qin ordered the king to be more than the king, into the chapter and the ministers to see the dynasty in the class. Why not? King Qin's heavy business? ”

When Shi Yan spoke, his eyes looked at the Si Yin of the Great Sima Mansion slightly, and he felt that the Great Sima Mansion really didn't understand the art of Shang Jia at all, because they didn't understand the art of Shang Jia, so they couldn't check the real pulse of the Qin State.

"Why?" In a certain book in the past, the widow Qing was called Qin Qing, who was Zhao Zheng's concubine, and what Yanran Chunlan Qiuju was good at. Later, he learned that Qin Qing was the widow Qing. However, knowing that Xiong Jing did not study in detail why there were huge rich businessmen like the widow Qing in a country like Qin, which was heavy on agriculture and suppressed business, the king of Qin also built her a female Huaiqing platform.

"The widow is pure, and the Ba people are also; Wu Shi is also a Rong person. The Qin State has always regarded the people of Rong Di as precious, and the head of its own country as cheap, which has been around for a long time. Although the two are big businessmen, because they are both Rong Di people, they built a platform to train classes. "Shi Yan's explanation was unexpected." This is true of the merchants, and so is the common people. The minister whispered that the king of Qin (Zhao) Xiang made an appointment with the Yi people: Qin committed Yi and lost a pair of Huanglong; Yi offended Qin and lost sake for a minute.

To kill a person, you need to pay Huang Long a pair, which costs more than ten gold; Kill a Qin person and pay for a minute of sake, but only five or six hundred dollars. The Yi people are as expensive as gold, and the lives of the Qin people are as cheap as dogs, and this is the policy of the Qin State to govern Rong Di.

Now I am allied with the Qiang people to seek Qin's Longxi, if the Qin people change their previous policy, the Qiang people are precious, and the Qin people are cheap, will the Qiang people still listen to me? Previously, the Qiang people were weak, and the Qin people chased them, and the Qiang people who were allied with me were strong, and the Qin people were noble. At that time, I only regarded the Qiang people as friends, but the Qin people worshipped the Qiang people as their fathers, who could compare? ”

Before Shi Yan's words, Zhibisi also reported the problem of Qin's 'Guiyi', but because the previous diplomatic strategy was to unite the Ba people and the Shu people and allow them to return to the country, the strategy was not easy to repeat, so he temporarily ignored it. By the end of the year, looking back on the diplomatic gains and losses of Ba and Shu, the state of Chu was completely defeated.

As Shi Yan said, the state of Chu 'only made friends with its people, but the Qin people worshiped them as their fathers'. On kneeling and licking kung fu ......, no, this can't be called kneeling and licking, Chu Envoy seems to be the divine envoy of Taiyi God, with a hard face to give gifts to the Ba people and Shu people. The Yujunba people were oppressed for too long and miserable, and they knelt and suffered, and the Shu people did not dump the Chu envoy at all, and the Langzhongba people simply killed the Chu envoy, cut off his head and sent it to Xianyang (fortunately, this is not the Chu people, it is the Langzhongba people who have settled in the old Yingying for a long time).

Of course, the Qin State is not kneeling and licking all the Yi people, and only those who can't be beaten and are difficult to deal with have this qualification. In short, it is to be afraid of the strong and bully the weak, and to bully the weak and afraid of the hard. This is the same as the common people, whoever can hurt him, he will slap him; Whoever will treat him well, he will bully. There are too many nobles in the Great Sima Mansion, and they don't understand the logic of the common people, so they can't take the pulse of the Qin people.

"The Qin people are like this, but the Qiang people are like this?" Shi Yan was speechless, but there were still opponents, and Yin Yidrunk, the Ministry of Military Affairs, was very unimpressed with Shi Yan's words. "The minister lived in Qiang for several months with the king, and the Qiang people and my Chu relatives did not worship Taiyi, but they worshipped fire. The Wuyi sword was burned by the Qin people and did not die, and the Qiang people worshiped it as a great hero.

The Chu people and the Qin people have a grudge of no more than a hundred years, and the Qiang people have a grudge with the Qin people for hundreds of years. The Qiang people allied with the Qin people because they served themselves as their fathers? This is a big fallacy! The Qin people regard my Chu people as their fathers, and my Chu people will be in alliance with the Qin people? ”

Yi is drunk and young, and he can be the minister of the Ministry of Military Affairs, one is because his father is Yiyang Hou Yisu, and the other is because he is the private of the king (the husband of the sister is called private). The young man's speech was full of sonorous words, his voice was loud, and his persuasiveness was really not as good as Shi Yan's.

"If the Qin people really serve my Chu people as their fathers, it may not be impossible to make peace with the Qin State." Nao smiled slyly, in exchange for a drunken glare. "The king, the minister thinks that he should be cautious of the Qiang people, if he can lead the people to attack Longxi, and I will be at the source of the Han River, and he can give him armor; If you can't, you won't. ”

"How can it be!" Dazai Jin objected. "This winter, the Qiang people will marry their daughters to the king as their wives, and since then the Qiang people are the state of my Chu State marriage alliance, and they treat each other like this, but the Qiang people will turn their backs on Qin. The minister heard that the Qiang people died in battle as auspicious, and the end of the illness was unknown, and this kind of person did not know the benefits and losses, how could he live with the heart of the common people in the market. ”
