Stretching for 1,500 kilometers from east to west and more than 100 kilometers from north to south, the Qinling Mountains are located in the central and western parts of China with a unique geographical location. The majestic Qinling Mountains play a dual role, with the warm and humid south of Lingnan and the cold and dry north of the northern foothills, and the Qinling Mountains as a landmark watershed that cuts the natural world into two distinct seasons. A mountain range not only divides two different seasons, but is distributed in Shaanxi, which belongs to the same province on the north and south sides of the Qinling Mountains, and its Guanzhong Plain and Hanshui Basin reflect different regional cultures and folk customs.

The Guanzhong Plain may have been deeply influenced by the ancient capitals of previous dynasties, and its cultural heritage is colorful, and its folk customs are more open and inclusive. The people of the Hanshui River Basin in Lingnan are simple and fierce, and they are greatly influenced by the proximity to Sichuan. For the sake of safety, Ouyang Jian's entry into Sichuan was a secret trip, and he did not inform the Sichuan warlord Liu Xiang. At Xi'an Station, Ouyang Jian got on the eastbound train in a grand manner, and got off at the previous station, disguised himself and headed in the direction of Qinling.

At present, there are 4 transportation routes through the Qinling Mountains, and Ouyang Jian chose to take the Meridian Road, because this route is the most convenient to enter Sichuan. In the Tang Dynasty, in order to enjoy the lychees abundant in the south, the means of transportation was to pass through the lychee road and meridian road of Bashu to Chang'an. At that time, Yang Guifei liked to eat lychees, and the imperial court built a lychee garden in Fuling, Sichuan, and the lychees produced went directly to Chang'an through Daxian County into the lychee road and the meridian road, and the fast horse and whip it for three days, so as to prove that this route is the most convenient.

The Tang Dynasty poet Du Mu's eternal swan song - "Passing the Huaqing Palace Quatrain", vividly depicts the luxury of the dynasty. Its: Chang'an looks back at the piles of embroidery, thousands of doors on the top of the mountain are opened, and the concubine laughs when she rides the red dust, and no one knows that it is a lychee! The first sentence "Looking back at Chang'an" is extremely important. At that time, Chang'an was the capital of the Tang Dynasty, and the Ming Emperor was supposed to deal with the government affairs in the capital, and the imperial concubine should stay in the capital to accompany her, so the lychee should be sent to Chang'an City. However, the emperor and the concubine were having fun in Lishan, which led to the artistic conception of the first sentence "Chang'an Looking Back at the Embroidered Pile".

During the Tang Ming Emperor, Lishan was full of flowers and trees such as splendor, so it was called Xiuling. Use "embroidered piles" to write the general appearance of Lishan in the distance of "one ride", which is lifelike and very expressive. The second sentence inherits the past, "the top of the mountain is opened by a thousand gates", and the people on the mountain see a horse galloping, and open the mountain gate in turn to pass unimpeded. Immediately after the suspense was solved, a ride on the red dust sweated like rain and was unspeakably miserable to serve the lychee, and the concubine only smiled and was happy when she got the lychee. In contrast, the image depicts a wordless condemnation of arrogance and lasciviousness.

In addition, there are three passages through the Qinling Mountains, namely: Chencang Road, Fu Luo Road, and Bao Slope Road. Chencang Road starts from the north through Baoji Dasanguan, along the upper valley road of the Jialing River through Feng County, Mian County to Hanzhong, and then along the Jinniu Road into Sichuan. In history, "Ming Xiu plank road, secret crossing Chen Cang" refers to this route. At present, Chencang Road has evolved through the dynasties and is the most important trade route through the Qinling Mountains. The Bao Slope Road and Fu Luo Road located in the middle have been sparsely visited due to the evolution of history.

Ouyang Jian browsed the scenery all the way through the meridian road and felt the ancient wind all the way. Meridian Road is the first time he has walked, intuitive peeping, the opportunity is rare, I am afraid there will be no time to travel in the future. After the beautiful canyons and passes, the Hanzhong Basin appears head-on, and its scene presents the charm of the south of the Yangtze River. At this time, Ouyang Jian raised his eyes and looked into the distance: "Although this is still the boundary of Shaanxi, it is like returning to the south of the Yangtze River. It is warm like spring all year round and has abundant rainfall. ”

"Shopkeeper, this world is really strange, and this scene is actually like this across the mountain." The guard Xiao Wang was confused, since he was secretly entering Sichuan in disguise, Ouyang Jian naturally pretended to be a businessman. "The east-west direction of the Qinling Mountains is like a barrier, blocking the southward ・・・・・・ of warm and humid airflow." Ouyang Jian took the opportunity to popularize geographical knowledge and let them increase their knowledge subtly, which was one of the most effective means. Therefore, Ouyang Jian taught the guards and the four special combat team members as long as he had time on the road, so that the people around him could continue to accumulate the ability to understand the world and increase their talents. Therefore, Ouyang Jian is very selective in selecting his entourage, with the aim of cultivating available talents in an eclectic manner.

Before Ouyang Jian left Xi'an, he took special care of Zhang and Yang, Hanzhong has abundant rain and is uniquely blessed, and it must be built into a grain base in the future to ensure the food supply of the northwest strategic base. In particular, the entire Hanzhong Plain has been effectively utilized, and its role is immeasurable. Ouyang Jian passed on the advanced rice seedling technology to Zhang Yang without reservation, and in view of the fact that the Hanshui Basin is the rice producing area of Shaanxi, and asked Zhang Yang and the others to vigorously develop rice cultivation in the Hanshui Basin. Ouyang Jian judged that if advanced glass greenhouse seedling technology is adopted, the yield of rice can be increased by at least 30%. In this era, it is self-evident why the yield has increased by three percent. If scientific cultivation is carried out, the yield of rice may be doubled.

Ouyang Jian and his entourage arrived at Ziwu Town, Xixiang County, and planned to go to Hanzhong to have a look, but considering the itinerary, they immediately dispelled the idea of going to Hanzhong. The reason is that the time is urgent, it is now mid-October, after Ouyang Jian visited Liu Xiang, he will go directly to Wuhan along the Yangtze River, and then he will stop in Wuhan. Taking advantage of the opportunity to pass through Wuhan, there are some measures to discuss with Gao Guoying. He must return to Jiujiang before the end of the year, because Runzhi and Zhu De will come to Jiujiang to investigate, so Ouyang Jian must hurry up.

Ouyang Jian and his entourage entered Sichuan from Bazhen to Wanyuan, stayed in Wanyuan for a day, and continued to Chongqing. The group followed the ancient lychee road, wearing stars and moons, and arrived in Chongqing in October and late October. Ouyang Jian knew in his heart that Sichuan had entered a period of stability, and Liu Xiang had completely controlled Sichuan. Last year, Liu Wenhui defeated Xikang, and Liu Xiang successfully controlled the Chengdu Plain. In addition, due to Jiangxi's covert support for Liu Xiang, Liu Wenhui lost more severely than the original history in the Battle of Erliu, and his troops could only survive in Xikang.

At the beginning of the year, Liu Xiang, in his capacity as commander-in-chief of the Nationalist Government and chairman of Sichuan Province, commanded the army to force Liu Wenhui to surrender. After the peace talks between the Kuomintang and the Communist Party, Liu Xiang was appointed commander-in-chief of the 7th Route Army of the National Revolutionary Army. At present, Sichuan is monopolized by Liu Xiang, Ouyang Jian came to Sichuan this time, firstly, to deepen the relationship between them with Liu Xiang and continue to cooperate, and secondly, to offer advice to Liu Xiang. Last year, Jiangxi sold a large number of obsolete weapons to Liu Xiang, and Liu Xiang took advantage of this to strengthen his own strength, and in addition, he also made a lot of money. At the beginning of the year, Jiangxi sold Liu Xiang 100,000 rounds of ammunition at a cheap price, which made Liu Xiang increasingly dependent on Jiangxi.

In the future, the Nationalist Government will inevitably retreat to Chongqing, so Ouyang Jian must advance his defense. A few days later through Wanyuan, Dazhou, and Guang'an, Ouyang Jian and his party arrived in Chongqing. When we arrived in Chongqing, the sunset had put away its last rays, and the sky was still bright. The search was not strict when entering the city, so it was easy to enter the city with the weapons you carried. After finishing my meal at a nice restaurant, I chose to stay in a hotel on a high ground to make it easier to explore the landscape of Chongqing.

Due to the high terrain, the hotel has set up an observation deck on the hotel for the convenience of travelers and to attract business. After settling down, Ouyang Jian climbed onto the platform above and looked up, the sky was still bright at this time, and although the scenery outside was a little blurry, he could make out the appearance. Although the Zhongliang Mountain and the Causeway Mountain on both sides are hazy, the shadow of the mountain range is faintly visible. The current Chaotianmen Wharf is very clear, and the busy wharf is crowded and bustling, showing a unique shipping scene in the mountain city.

The mountain city is located in the urban area of the Yuzhong Peninsula, with undulating terrain, scattered houses, and winding streets. Relying on the golden waterway of the Yangtze River, the mountain city is the only way to connect Sichuan with the hinterland of the south of the Yangtze River, which has laid the importance of the mountain city of Chongqing as a shipping terminal. Ouyang Jian knew better in his heart that with the smoke of war, Chongqing would become a world-renowned companion capital in the coming years, and millions of people would have to move here.

Time passed quickly, and just as Ouyang Jian was thinking about it, the lights of ten thousand homes began to envelop the mountain city. Looking at the night scene of Chongqing, Ouyang Jian's thoughts once again entered the wild horse that was out of control. There will be changes in Jiangxi, changes in the northwest, and perhaps there will be significant changes in Sichuan. All this is bound to have a profound impact on the future anti-Japanese battlefield. Ouyang Jian knew that the changes in front of him could not affect the overall situation, and the overall strength changes between China and Japan were not obvious. The changes in Jiangxi and the northwest will prompt the Japanese army to invest more troops in combat, which is Ouyang Jian's first goal. The effects of the changes in Jiangxi and the Northwest will not become more effective until the outbreak of World War II, when the Chinese battlefield will still be a bitter war of resistance, and this will not change.

How to make the Japanese army pay more costs, how to get more assistance from the United States, that is to say, to make the United States pay more attention to the Chinese battlefield in the future, this is Ouyang Jian's key consideration. After all, he is an "outlier," and it is his duty to think about the dividends after the war, and it is his duty to obtain greater benefits in the stage of the great counteroffensive and how to put China in the best international position after the war. No one knows better than him where history is heading, so he has to think from a strategic perspective.

"Shopkeeper, it's time to rest late at night!" Guard pony alerts. Ouyang Jian took out his pocket watch and took a look, and sure enough, it was late at night. At this time, the mountain city fell asleep, the noisy dock lights dimmed, and the lights in the city gradually disappeared. When I woke up, it was already dawn. Ouyang Jian got up again and climbed onto the high platform. October is the best season in Chongqing, the air is dry and there is no pungent musty smell. Ouyang Jian took a big gulp of fresh air and began to move his limbs simply.

After the morning exercise, after a brief wash, Ouyang Jian and his subordinates went to the street food stall below the inn for breakfast. After eating breakfast, Ouyang Jian cleaned up and ordered the four guards to stay in the inn and not to go out casually to cause unnecessary trouble, and then took the guard Xiao Wang and went straight to the Sichuan General's Mansion. Due to the topography, the number of rickshaws in the mountain city of Chongqing is very small, and people with money and status go out to sit and carry poles. The pole is shaped like a chair, with four wooden poles extending from front to back, and is carried by two people.

The guard Xiao Wang wanted to hire a pair of poles, but was stopped by Ouyang Jian. It's not that Ou Ouyang is hypocritical, but that he is not used to lifting the pole. In addition, walking can more intuitively observe the street view of the mountain town. The sun rose a pole higher, Ouyang Jian and the guard Xiao Wang inquired all the way, and soon, the official residence of Liu Xiang, the Sichuan general's mansion, appeared in front of him.
