The plank road stretched for five miles, and then came to a source of Baoshui. Here, everyone took local materials and repaired the plank road on the hillside by the water.

Unlike the Sloped Valley, the Valleys are longer, with more cliffs on both sides and harder stones. If there is no stone cave that was dug in the past, it is very difficult to make a hole in the stone wall now. There is also a gentle place to rest in the valley every few miles, enter the valley, there are both wide valleys, there are steep cliffs that stretch for dozens of miles, to this kind of place, there is almost no other choice, can only come back every day to rest, the time consumed on the road is longer than the construction time. The most difficult thing was that there were no people along the way, only wild beasts, and all supplies had to be brought in from the sloped valley along the repaired plank road.

Zhang Lu tried his brains and couldn't think of a way to shorten the time spent on the road, and the second month was over. The convicts came back along the repaired plank road, and the 10,000-strong procession lined up in a column, which was about ten miles long from the head to the end of the team, and walked for three days before they walked out of the valley and returned to Xianyang on a boat. And the first batch of convicts who were working last month reappeared at the mouth of the valley after filling the shortfall. Although Zhang Lu and the others did not come up with a better way, they had to take them for three days and return to the construction site.

This hasn't gone far yet! If you build 500 miles away, how can you complete the rotation? How can I keep my supplies afloat? How can communication with the base be maintained?

On this day, Zheng Anping couldn't help asking: "What does the lord think, but he doesn't raise his eyebrows?" ”

Zhang Lu said: "The army has entered a heavy place, and it is difficult to continue the backup, what can I do? ”

Zheng Anping found that this was not what he was good at at all, so he had to thank: "This is not something that the minister can know." But what does the lord mean? ”

Zhang Lu said: "Before the road, before the army." The veterans of the division are tired, and the grain is behind, and the advance is weak, and there is no way out, so what can I do? “

Zheng Anping said: "It's not so-called. The road ahead is frank, and the support is endless, is there no way out? “

Zhang Lu said: "Bao slope road 500 miles, now is not 100 miles, all the cliffs are crossed, if under the fortified city, there is no way to enter, and there is no success in retreating." “

Zheng Anping said: "Under the fortified city, if you attack it from time to time, it will be broken." “

Zhang Lu said: "Today, it is a hundred miles, and the backup is still there." If you travel 500 miles to Baogu, where will the backup be? “

Zheng Anping said: "The lord has no plan. Five hundred miles to the Bao Valley, He Lao slanted valley to transport grain, since the Bao Valley transported! “

Zhang Lu's eyes lit up and said, "Where is the origin of Baogu?" Can you get its food? “

Zheng Anping said: "The minister is not familiar with geography. With affection, it costs people's strength, consumes ministers' wealth, and digs a plank road of 500 miles, and there will be heavy benefits in it. Those who benefit from it are only praised and oblique. The inclined valley has to pass Xianyang, and the valley is connected to Shu, and its wealth and Shu are also matched with Xianyang, which is profitable! “

Zhang Lu said: "The words of peace are also enlightened." May peace please Mr. Right. “

Mr. Che You was known to Zheng Anping, and he also knew that he was a disciple of Mangmao, and when he arrived in Qin State, he went incognito, changed his name to Mr. You, and also told Zheng Anping. Zheng Anping immediately found Mr. Che You. Zhang Lu asked, "Where does Mr. know where Baogu leads?" Can it be a big military fund? “

Mr. Che You said: "Hearing that Bao obliquely leads to Qin Shu, the oblique valley is in Qin, and there is no inadequacy, and Baogu will pass through Shu." Where is in Shu, I really don't know. “

Zhang Lu said: "More than 500 miles from the Xiegu Valley to the Baogu Valley, it is sparsely populated, and it is difficult to transport. If you only rely on the sloping valley to feed the grain, it will be difficult. In the opinion of the ministers, if you have to praise both ends, it will be a good thing! “

Mr. Che You thought about it and said, "There is something to do!" The public ride Sima Jin, the Qin people also, or know the matter of Baogu, you will consult it! “

Now the camp of the convicts is located next to an open river valley, ten miles away from the construction site, and dozens of miles forward from here are precipices, and it is rare to find a place to camp. Ten thousand people set up twenty camps, and Zhang Lu's camp was in the center. Sima Jin has his own battalion of 500 people, and he has set up a battalion on his own, which is next to him. Zheng Anping went to the camp tent to invite, and Sima Jin was fighting with Gai Nie. Seeing that Zheng Anping was coming, he hurriedly ended the sword fight, changed his clothes, took Gai Nie, and came back with Zheng Anping. On the way, Sima Jin asked: "Keqing is calling, what is the matter?" “

Zheng Anping said: "The lord is not familiar with the geography of praise and obliqueness, and he is willing to consult with the public!" “

Sima Jin said with a smile: "If you talk about others, the minister may not know; If the geography of the slope is praised, the ministers and the ancestors and fathers are different from each other, or they may know it. “

When he arrived at Zhang Lu's tent, Zheng Anping reported that Zhang Lu and Mr. Che You came out together, entered the tent, and after the ceremony, the guests and hosts sat opposite each other, and Zheng Anping sat down.

Zhang Lu said: "The plank road is also moving forward, gradually leaving the sloping valley, and the grain road is getting farther and farther away, and the backup is difficult to continue." If the public has been in the camp for a long time, he will have something to teach me. “

Sima Jin said: "It's just a hundred miles, and it's not his labor to carry grain." However, there are few people along the way, and it is difficult to set up camps, and if it rains or snows, there will be people who die of disease. “

Zhang Lu said: "The slope is five hundred miles. Thousands of miles of grain, twenty is the first to come, and it is difficult to help. And five hundred miles, it is difficult to reach in January, and the situation is to build! “

Sima Jin didn't know what Zhang Lu meant, and said, "Don't worry about Zhang Qing! Zhang Qing has an order, the ministers will be frequent, try their best to serve it, and rest without death! “

Zhang Lu said: "It's not so-called. I had a plan, but I didn't know the geography, so I asked for advice. “

Sima Jin said: "Qing but if you ask, those who know will not dare to hide it." “

Zhang Lu said: "Where is the Baogu Valley, where is Shu, how can there be a Qin official?" “

Sima Jin smiled when he heard this, and said: "The valley is passed, and the natural Qin land, if it is not, what is the point of cultivating the Baodi?" “

Zhang Lu said: "Where is the lead?" “

Sima Jin said: "Its name is Nanzheng, and it is also governed by Hanzhong." “

Zhang Lu said: "Please talk about Hanzhong and Nanzheng." “

Sima Jin straightened out his thoughts and said: "Those who lose Nanzheng, or Yunzheng people lose their country, run south here, hence the name." In the twenty-sixth year of the reign of the Gonggong, the south of Qincheng was in Zheng, and it was two hundred years old. However, in the south of Zheng and Xianyang, the mountains and rivers are repaired, and the rotation is subdued and rebelled. In the ninth year of King Huiwen's reign, the ancestors mistakenly led troops to attack Shu, and Nanzheng returned. In the thirteenth year, Qin defeated Chu Danyang, beheaded 80,000, and obtained Chu Hanzhong, which was combined with Nanzheng and Hanzhong as Hanzhong County, and governed Nanzheng. Out of the Bao Valley, that is, into Nanzheng, Hanzhong County guarded in Yan. Daonan Zheng, out of the Golden Bull Road, that is, Shu County. “

Zhang Lu was overjoyed when he heard this, and said: "Wei Gongcheng, the minister knows!" Ling Zu went down to Nanzheng and Shu, and its way passed. Today, the public can walk the ancestral road, and he is also filial! “

Sima Jin said: "Since Zhang Qing knows the geography of Hanzhong, what should he do to get through?" “

Zhang Lu said: "The minister is willing to send the disciples of Nanzheng, from the south to the north, and meet me in the road, but what?" “

Sima Jin said: "If you get the Qin King Soldier Talisman, you don't have to worry about it." “

Zhang Lu saluted: "Tired of the public ride, how can I bear it!" The minister should invite the king, or disturb the public ride again, and I am willing not to resign! “

Sima Jin said: "If there is a decree, dare to resign!" The two bowed and retreated. When leaving, Sima Jin did not forget to take Gai Nie to play with the sword.

Zhang Lu didn't dare to slack off, so he added some firewood by the bonfire, and by the flickering firelight, he wrote a letter, sealed it, and handed it to Zheng Anping, asking him to go out of the valley as soon as possible tomorrow and hand it over to Wang Ji who stayed in Yixian. Zheng Anping stayed in Yixian County to assist Wang Ji in his work; If Wang Ji needs anything, he will report it immediately.

Zheng Anping knew that his suggestion had been adopted, and he was naturally elated, and almost lost sleep at night. After dawn, I hurriedly ate breakfast, immediately stepped on the plank road, and rushed back to the valley. Hundred miles of plank road, Zheng Anping spent half a day to finish, out of the valley after a short rest, that is, to Yixian County, found Wang Ji in the pavilion.

Wang Ji heard that Zhang Lu was going to call Nanzheng's prisoners to repair the plank road from south to north, although he also knew that it was a good way, but the procedures involved were complicated, and too many people needed to be alarmed; If you can't get it, the plank road here is almost repaired, and the procedures over there haven't been completed yet. He proposed his idea to Zheng Anping, and if it was not very necessary, it was better to maintain the existing plan and not change it. Once it is changed, it involves remote counties and counties, and there are many constraints!

Zheng Anping encouraged him that if there was no other good plan, Zhang Lu would not dare to alarm him; Today's situation is urgent, and I am about to show my arms! Wang Ji didn't know if he was wearing these high hats, or if he had already figured it out, hesitated for a moment, and formulated a customs clearance plan. He said to Zheng Anping: "Today, the minister goes to see the king of Qin, and the king discusses it with the prime minister, and the county guard with the discussion, not the one who counts above." In the opinion of the ministers, Sima Jin, Wu Anjun is also close, don't write a brief, and prepare his strategy; Hanzhong guards, Sima is wrong, and Jin Ziyi said it to make it self-effective. If you are subordinate to the king, you will be harmonious! “

Under the guidance of Wang Ji, Zheng Anping only had dinner in the pavilion, and then hurried back to the construction site, and when he arrived, it was already late at night. Zheng Anping woke up Zhang Lu in his sleep and reported to him Wang Ji's idea. Zhang Lu thought about it in his heart and felt that there was some truth. After ordering the army the next day, he left Sima Jin and asked him to write letters to Bai Qi and Hanzhong Junshou respectively to inform them of the incident. Sima Jin did not refuse, asked Zhang Lu for a slip, and immediately discussed with Zhang Lu to write two letters, sealed them with his own seal, and dispatched two appropriate people to send letters to Bai Qi and Hanzhong respectively.

It is good to send a letter to Xianyang Baiqi, the road is 100 miles, although it is far away and easy to pass. It is difficult to send a letter to Hanzhong, and it will take at least ten days to walk normally for these four or five hundred miles; Moreover, the distance was too far to be safe for one person, and fifty guards were assigned to him. This person has an old relationship with Hanzhong County, but he is not good at talking, so he asked Zhang Lu to send a person who can speak to assist. If you want to be able to speak, no one else can compare to Zhang Lu, but it is impossible for Zhang Lu to leave. Mr. Che You couldn't stand the fatigue of the journey, and he didn't think about it, so he thought about it and had to ask Mangwei to come out. Mang Wei often deals with some administrative affairs by Mangmao's side, even if he is not able to speak well, he can be regarded as sharp. Zhang Lu and Sima Jin summoned the two to the tent, carefully explained to them the current difficulties and solutions, and asked them to persuade the county guard to agree to start construction from Nanzheng. It wasn't until both of them understood.

In the middle of the day, two groups of messengers set out on their way. The one going to Xianyang is the newly repaired plank road; To Hanzhong, you can only walk along the broken plank road and walk carefully.
