The ancestor of the Qin people, Da Luo, originally lived in Dog Hill, and the eldest son Cheng inherited Da Luo's inheritance and still lives in Dog Hill; The second son, Feizi, was enshrined in Qin because he was favored by King Zhou. Therefore, if you want to talk about authenticity, Qin wants to call Dog Hill Dad. At that time, the source of the Han River was near Inuqiu, and it was called "Tianshui". Today, Tianshui flows into the Jialing River to the southeast, but at that time, Tianshui turned and flowed eastward, after converging the Baoshui, Yangshui and Yudai rivers, in a relatively wide valley between the Micang Mountains and the Qinling Mountains, alluvial a fertile basin was formed, and Nanzheng was on the south bank of the Hanshui River in this basin.

Baoshui Taniguchi originally had a small country, Baoguo. King Zhou You's expedition to Baoshui, destroyed the Bao country, snatched the beauty of Bao Guo to the palace, and made him the queen, which is the story of the "Beacon Fire Opera Princes".

During the reign of King You of Zhou, it was his own uncle Zheng Huan Gong who was in power. Of course, the ruling Zheng Huan Gong saw the decline behind the prosperity of Zhou Tianxia, although he left a way back for himself early and relocated the country to "Luodong", which was still very wild at that time, but the fall of the Zhou Kingdom was still too rapid, and he only had time to take some of the women, children and wealth out of the tiger prison, and was martyred for no reason. The remnants of the Zheng people fled along the road where King Zhou Youwang marched to the ruined hometown of Baoguo, where they settled. This may be the origin of Nan Zheng.

The Han River continues eastward, passing through a canyon and into another open valley, where a basin is also accumulated. This basin, along with the surrounding mountains, once belonged to a powerful state, the Yongguo. Yongguo did not build its capital on this basin, but on an isolated hill,—— probably not an agricultural society at that time. Under the leadership of the king of Chu Zhuang who "soared into the sky and shocked the sky", the Chu people took advantage of the rash advance of the mediocre people, and in the dilemma of famine inside and strong enemies outside, they issued a Jedi blow, and joined forces with Qin and Ba to destroy the Yong State and set up Shangyong County, and the ugly duckling became a white swan from then on. Later, Xicheng County was established in the basin; This basin is called Hanzhong because it is located in the middle of the Han River, and it is an important line of defense against the Qin army in the west, and it is also an important starting point for entering and exiting the Qin land. It can not only go up the Han River and enter Yi County in Qinjinggi through the Baoxiao Valley, but also through the Meridian Water, another tributary of the Han River, to Xianyang.

In the state of Chu, the front line of Hanzhong, Shangyong is the rear, so the Hanzhong County of Chu includes Shangyong, and even relies on Shangyong. But after Qin seized Hanzhong, the situation was somewhat different: although Hanzhong was still the front line, the rear support became Nanzheng, so Qin's Hanzhong County included Xicheng and Nanzheng, while Shangyong was assigned to Nanyang County by Qin.

When the Qin army invaded Shu, Sima Cuo should have stayed here for a long time, accumulating military resources, resting troops, and preparing reserves. After the conquest of Shu, the Shu people rebelled many times; At that time, the Qin State returned Shangyong to the Chu State, and the pressure on the Chu State in the east was also huge. Therefore, when Wei Ran first served as the prime minister of Qin, he recommended the famous Hercules Ren to be the guard of Hanzhong. After Ren Wei's death, the king of Qin personally toured Hanzhong in the south.

After hard work, Qin finally established Nanyang County two years ago. With Nanyang County, the threat to the east of Hanzhong County was basically lifted, Shu County to the south, Qin Mainland to the north, and Hanzhong changed from a border county to the interior. A large number of soldiers in Hanzhong will be useless. At this moment, Sima Jin's messenger arrived.

Sima Cuo was in charge of the military administration of Shu for decades, and Hanzhong was an important base. Although Sima Cuo has passed away now, Yu Yin is still there. Although the messenger was only a retainer of the Sima family, he was also warmly received by Hanzhongshou. After reading Sima Jin's letter, Hanzhong Shou fell silent and said for a long time: "The order of the public ride, the minister did not dare to resign." However, Hanzhong is in the place of attack and defense, and there are many dangers in the passes, and although there are many soldiers, it is difficult to prepare; Don't worry about him! ”

The messenger said: "The public multiplies his words, the establishment of Nanyang County, and Hanzhong has no worries; The pass of praise and oblique is also, and there is the benefit of northern aid in Hanzhong. It is also for the benefit of Hanzhong. ”

Hanzhong Shoudao: "The words of the public vehicle are naturally true. However, this praise ramp is good after the pass. The passage of the ramp is also, or after a few years, the veterans of the division are tired, can they ensure that there is nothing unspeakable? ”

Mang Wei said: "The pass of praise and oblique is also a few months, more than a year, and there is no reason to take several years." ”

Hanzhong Shoudao: "The words of the son are bad. The slope is very steep, and the former misguided army and the south are also quite trapped in the difficulty of the road, and those who cannot be repaired are also difficult to cultivate. The hairpin is from the sloping valley to, or easy to see the danger of the valley. The slope valley is also to the Bao Valley, and its steepness is unspeakable, and the real heaven is also abyss. Although the sloping water is dangerous, the flow is slow and the shore is flat; The water is not the case, the turbulence hits the stone, the wall hangs on both sides, and it is often hundreds of miles without end. People are here, standing with nothing, at a loss with their hands, not daring to see, and hearing nothing. The hairpin has experienced it firsthand, and you should know that what you say is true! ”

Mang Wei said: "The words of the king are yes. At that time, he was also frightened and incapacitated; Close your eyes and steady your heart, and you can get by. However, the traces of the predecessors are clear, and although the ministers are incompetent, they are willing to follow them. ”

Hanzhong Shoudao: "The son is here, and he wants to follow it?" ”

Mang Wei said: "Definitely! Those who are ministers are really kings! ”

Hanzhong Shoudao: "What is it for me? ”

Mang Wei said: "The former, the Han Dynasty rejected Chu in the east, the Shu in the south, the Zhurong in the Xiping, and the Qin guarded the border, which was a great achievement. Now the East Chu has been decided, and the king is not with Yan; Shu County is stable, guarding the monarch Mo and Yan; Xirong has no escape, Jingning in all directions, and the people are enthusiastic and celebrate peace, and it is useless to defend the king. Today, the king is all through the Shu road, and the public is in charge of Yan; Wu Anjun personally sent the prisoners to think that after that, Huayang Jun personally levied grain and straw as his aid; King Qin was in Zhangtai, and the marquis was in Xianyang; Weijia is full of people, and the merit is in the future. The public passenger has a proposition, and the monarch guards have an old relationship with the Sima family, and their merits are indispensable. Therefore, the ministers and others, wading through dangers and obstacles, came over the mountains and rivers, and sincerely wanted to keep the monarch into this thousand-year-old business, for the merit of eternity. The road of praise and oblique is five hundred miles up and down. From oblique to praise, it is necessary to do it, the death of the prisoner, the cost of grain, the transportation of grain before and after, and the daily gold. If the king can praise himself and welcome it, he will get a foot of merit if he welcomes a foot, and he will get a foot of karma if he welcomes a foot, which is impressive in his eyes and in his heart. Keqing was established early because of it, Wu'an was less in vain because of it, Huayang was not distributed because of it, and the Qin King expected, and the Marquis was enterprised, all of which saw the virtue of guarding the king. It's a success. The public ride is still insufficient, and he wants to make the king write to the king to see his sincerity and follow his work. The king knows the virtue of keeping the king, not the discussion of the public. Defend it! ”

These gushing words were naturally not thought up by Mang Wei temporarily, it was the result of joint discussions between Zhang Lu, Mr. Che You, Sima Jin and others, and Mang Wei just performed it.

Hanzhong Shou listened to this carefully prepared rhetoric, and was a little trapped, and asked, "Why is it that the public is also deep in Huichen?" ”

Mang Wei said: "The former wrongly sent the pawn of Longyou, and he will follow the river to the east, the food is not changed, the armor is not complete, and he relies on the virtue of the king to complete, so he will become the merit of Qianzhong." The wrong man did not dare to forget. However, the day is not a holiday, and the virtue is not repaid, but at the end, it is sincere to the children and grandchildren, and the virtue of the king must not be forgotten. Guarding the monarch and guarding the Han for several years, the public passenger is not visible. Although, the wrong public order did not dare or forget. Now that he has the convenience, he sent his confidants to come with books to seek for the king. ”

Hanzhong Shoudao: "The wrong prince entered Shu from Longxi, and after Hanzhong, the ministers should prepare the host, and they dare not pretend to be virtuous." And if the public will be wrong, the public will be reported on a different day. The minister did not dare to take the public ride, betrayed the wrong public virtue, and was willing to ask the king with a book. Qing waited and lived in the pavilion, and Rong Chen talked about the righteousness of the host. ”

When the retainer heard this, he replied, "When the prince hears it, he will be happy." "Hanzhong Shou summoned the post officer, ordered to take it to the pavilion station, and added a level of supply to the usual practice, and the retainers and fifty guards were all knights, but Mangwei had no lords. However, the Qin people are bold and have the tradition of "being with their sons", and those with high titles naturally share their meals with everyone.

After a day off, Hanzhong Shou took out a document, read it with his retainers and Mangwei, added a seal, and ordered the post officer to send it to Xianyang. Mang Wei said: "We should not wait for a long time, Gong Gong took a long look." This scholar and others are willing to take it to Yixian County and hand it to Xianyang in turn. ”

Hanzhong guarded the number and left everyone to stay for a few days, but Mang did not wait for the stubborn resignation. On the same day, we set off on our way home. On the way back, on the one hand, due to familiarity with the road conditions, I have experience; On the other hand, because I completed the task and was in a happy mood, the speed was a little faster than when I went, and with the time I stayed in Hanzhong, I returned to the construction site for nearly a month.

At this time, the second group of prisoners had returned from their term of office, and the third group of prisoners was on their way to the construction site. This month, due to the extremely poor working conditions, the construction progress was very slow. However, everyone was very happy to learn that Hanzhong Shou was willing to submit a letter to the King of Qin and took the initiative to express his willingness to repair the plank road from Baogu to the north. On the one hand, he let the messenger rest, and on the other hand, he sent Zheng Anping to deliver a letter to Yixian.

Zheng Anping arrived in Yi County and met Wang Ji first. When the prisoners were changing shifts, Zhang Lu and the others visited Wang Ji to find out Wu Anjun's attitude towards Hanzhong's involvement. According to Wang Ji's observation, Bai Qi read the letter and did not say much, but fell into a deep thought. Wang Ji entered the palace again to see the king of Qin, and the attitude of the king of Qin was still positive, saying that if he had to report to the court, he would be approved.

Zheng Anping came back as a post guard to deliver the letter. He saw Wang Ji first, and wanted to find out whether he would send the letter or not. If Wu Anjun is not very interested, or even disgusted, then it is better to slow down for the time being, and it is better to pass Wu Anjun's pass and send it again. However, the news I got in the past few days seems that this matter was not discussed at the court meeting, and Wu Anjun's attitude is not very clear. Wang Ji thought that it would be better to send the recital of Hanzhong Shou to the newspaper normally, urge this matter, and not let it sink.

The next day, Zheng Anping delivered Hanzhongshou's recital to the Yixian Post Station. After the post officer verified the seal and the place of issuance, he loaded it on a car with a pile of other documents, transported it to the ferry, and then loaded it on a ship and transported it to Xianyang.

The report of Hanzhong Shou delivered by Yixian County arrived in Xianyang on the same day and entered the Prime Minister's Mansion.
