The next day, Shi Yuan personally went to General Ma Chao's residence and learned detailed information about Hanzhong from General Ma Chao. Pen ~ fun ~ Pavilion www.biquge.info Hanzhong population of 100,000 households, you must know that at this time the population of Yizhou is only about 200,000 households, the importance of population in the Three Kingdoms period Shi Yuan heart is very clear, cold weapon era, the population is large, in order to have enough army, in order to have enough military food. Shi Yuan thought of the history of this period of time that later generations knew, after Cao Cao got Hanzhong, he continued to move the population of Hanzhong to Chang'an and other places within a few years, and finally when Cao Cao retreated, the population moved away was as many as 50,000 households, accounting for more than half of the population of Hanzhong, so that although Liu Bei later got the land of Hanzhong, many places were already deserted, so that Zhuge Liang had to move people from other places to Hanzhong. Thinking of this, Shi Yuan made up his mind in his heart, in this battle of Hanzhong, it is far from enough to just get the land of Hanzhong, the key is to find a way to preserve the population of Hanzhong.

Since ancient times, Hanzhong has been a battleground for soldiers, bordering Guanzhong in the north and Xichuan in the south. Between Guanzhong and Hanzhong, there are three valley roads that pass through the middle of the Qinling Mountains, which can be the passage between the two. They are respectively Bao Slope Road, Fu Luo Road, Meridian Road, among which the south entrance of Bao Slope Road is called Bao Valley, the north mouth is called Slope Valley, and the valley road is 470 miles long; Fu Luo Road, the south mouth is called Fu Valley, the north mouth is called Luo Valley, the march is not easy, it is easy to be blocked, the valley road is 420 miles long; The south entrance of the meridian road is called the meridian valley, and the north entrance is called the sub-valley, and the valley road is 660 miles long. There are two passages between Hanzhong and Xichuan, namely Jinniu Road and Micang Road. The Golden Bull Road starts from M County in the north to the big sword pass of the Sword Pavilion in the south, and the highest peak in the middle is called Chaotianling, and the Sword Pavilion is its throat at the southern end. Micang Road is named after the Micang Mountain, from Nanzheng to the south along the mountain range through Xishen Dam, crossing the Bayu Pass, after crossing the mountain range, along the Nanjiang River valley to Bazhong, from Hanzhong into Sanba, this is a shortcut.

In addition, the land of Hanzhong is not only the upstream terrain of Xichuan, but also the upstream of Jingzhou. The upstream trend of Hanzhong to SC is due to the topography, and the upstream trend of Hanzhong to Jingxiang is due to Hanshui. In the biography of Su Qin in volume 69 of the "Historical Records", it was written that Su Qin mentioned the convenience of Qin from Hanzhong to the Han River to attack the land of Chu Yingyan when planning the merger, "The first in Hanzhong, took a boat out of Ba, took the summer water to the Han Dynasty, and arrived at Wuzhu in four days." This fully shows that it is convenient to go south to Jingzhou and southeast from Hanzhong to the Han River.

Longxi is located in the north of Hanzhong, the terrain is higher, there is a relatively flat place between Longxi and Hanzhong, that is, the lowland of the West Han River Valley, which is a relatively flat passage from Hanzhong to Longxi. In history, Zhuge Liang's Northern Expedition was more than Qishan, precisely because of this relatively flat road, and the three passages between Hanzhong and Guanzhong were too risky in comparison.

When the autumn harvest was approaching, Shi Yuan and Kong Ming, who were in Chengdu, received a letter from the guards of Pujiaguan, and after seeing the news in the letter, the officials in Chengdu were immediately very surprised, and even more frightened, and they were too frightened to afford to fall ill. The letter later mentioned that Cao Cao personally led an army of 100,000 to attack Hanzhong, and the two sides are currently fighting fiercely at Yangping Pass, and have shown an invincible trend. After seeing the letter, Shiyuan and Kong Ming discussed with the generals and strategists in Chengdu, and decided to send the news and the opinions and ideas of everyone to Jingzhou as soon as possible to inform the lord, and at the same time, the soldiers in Chengdu also hurriedly prepared to set off at any time. However, since the autumn harvest has not yet come, there is not much military rations left in Chengdu at this time, and if you set off in a hurry, the military rations you bring are bound to be insufficient, which is a major problem that plagues Shiyuan and Kong Ming.

After the lord Liu Bei personally led the army to Jingzhou, the whole army entered the Gong'an Port, and did not send troops to attack the two counties of Changsha and Guiyang that surrendered to Eastern Wu, and the crisis in Lingling County was also relieved after the arrival of General Huo Jun. For a period of time after that, the army of Eastern Wu and the armies of Liu Bei and Guan Yu have been in a stalemate in the four counties of Jingnan, probably because both sides are unwilling to meet each other. Moreover, the envoys between the two countries also had frequent exchanges during this period, and in addition to the alliance policy of Lusu, the governor of Soochow, the relationship between the two countries generally showed an upward trend during this period.

Although there has been a war in Yizhou in the first two years, the impact of the war in the past two years on this year's autumn harvest is almost none, and the grain output has a tendency to catch up with and surpass compared with the previous two years, which makes Shiyuan, Kong Ming and other officials in Yizhou feel very happy. When the autumn harvest was about to be completed, the letter sent by Liu Bei, the lord of Jingzhou, also arrived in Chengdu, in which it was written that the generals such as Yuan He, Ma Chao, and Zhang Ren led 30,000 horses to Pujia Pass immediately, and brought more grain and grass for the 50,000 soldiers he personally led next year.

After receiving the letter from the lord, Shi Yuan and the others immediately took action, because after receiving the letter from the general of Pujiaguan, the soldiers in Chengdu had been preparing to set off at any time, so in less than two days, 30,000 soldiers were all ready.

Before leaving, Shi Yuan received a big gift, which made him very happy. That is, Kong Ming continued to study day and night during this period of time, and finally developed the profit and loss repeater before Shiyuan's departure, and 20 of them have been prepared.

This time he set off for Pujia Pass, Shi Yuan asked Guangyou to go with him, because Shi Yuan wanted to train Guangyou into an excellent general, and the most important thing to fight a war was experience, and this time Guangyou followed him to learn and learn. Why did Shu Han die so early in history, and the lack of successors was also a major factor, Shi Yuan had already noticed this at this time, so he let Guangyou follow, and it was also considered for the future of Shu Han. As for the appearance, Shi Yuan let him stay in Chengdu City, Shi Yuan always felt in his heart that girls should face each other at home, and fighting is not what girls should do.

On this day, at the gate of Chengdu City, officials at all levels are here, sending off the 30,000 soldiers who went on an expedition to Hanzhong, and Hanzhong is Chengdu An, which is the truth that the entire Chengdu people know, so everyone hopes that this time the army can win a battle to ensure the peace of Chengdu. Shi Yuan sat on a horse, looked at the people of Chengdu at the city gate, and swore in his heart that he must take Hanzhong and ensure the peace of Chengdu. Looking at the flags flying in the wind, Shi Yuan shouted, "Let's go!" ”
