Lantian County is not far from Chang'an, and they set off before dawn the next day and arrived in Lantian County at noon.

Lantian County Commander Zhao Jun was born as a clerk, when Zhu Zhu controlled Guanzhong, he was promoted from a small official to Fengxian County Lieutenant, when Guo Song cleaned up the officialdom in Guanzhong, he found that he was capable and honest, so he continued to be reused and promoted to the county commander of Yunyang County.

Because he did a good job in Yunyang County's business, making Yunyang County the largest livestock trading center in the world, and he handled Guo Ping's affairs well, he was transferred to Lantian County two years ago, and he served as a county commander in Gyeonggi Province for two consecutive terms, which means that the next one will be directly promoted to history.

Zhao Jun heard that the king of Jin and the ministers of the political hall had arrived, and hurriedly took the county and the county lieutenant out of the city to greet him, he had been notified by Pan Liao in advance, asking him to prepare lunch, Pan Liao repeatedly told him not to be extravagant and wasteful, this is more difficult than preparing a banquet, Zhao Jun racked his brains, and prepared some special dishes.

"Humble Zhao Jun see His Royal Highness! See all the prime ministers! ”

Guo Song still remembers him, when his eldest sister was in Yunyang County, it was this Zhao County who decided the case, which reunited their mother and daughter, and also allowed him to find the eldest sister, Guo Song has always had a good impression of him.

Guo Song smiled and said: "Zhao County Order, we are all hungry, but do we have food?" ”

"Yes! Yes! The humble post has prepared the special meals of Lantian County, and I invite His Royal Highness and all the ministers to move to the county office. ”

Zhao Jun invited everyone to the county office, and the county government specially arranged a small courtyard, the yard was full of green vines, full of greenery, a peach blossom was blooming, and the breeze was blowing, which made people feel refreshed.

There are more than a dozen bamboo and rattan circle chairs in the courtyard, sit down wide and comfortable, several maids serve tea, Guo Song sits on a wide circle chair, quite a bit of a sofa feeling, he took a sip of tea, the water quality is clear and sweet, and the sencha is particularly fragrant and smooth.

"Good water!" Guo Song couldn't help but praise.

Of course he can drink it, the tea is not very outstanding, but the water is good.

The Xiangguo also praised the good water, Zhao Jun was encouraged, and hurriedly said: "This is the spring water received from the mountains this morning, one of the springs was discovered by Master Jiaoran, he was full of praise, we all call it Jiaoquan, many people in the county go to pick up water in the middle of the night, and there are people who transport water to Chang'an to sell, go to collect water at the third watch, and it can be sent to Chang'an in the morning." ”

Guo Song was quite moved, he gave Du You a look, Du You understood, and said with a smile: "This is Zhao County's order, let us drink such good water, what will we do in Chang'an in the future?" I'm an old arm and leg, and I have to run here in the middle of the night every day? ”

Everyone resonated, Zhao Jun suddenly understood, and immediately said: "In the future, the water of the imperial court will be covered by Lantian County, and the county will send water to the imperial court every morning." ”

Guo Song smiled slightly: "Give a little more, I want to buy it privately." ”

"No, Your Highness needs to buy it, Weichen will just send another copy."

Guo Song shook his head, "Zhao County's order to send water to the imperial court is public-to-public, you don't need to buy it, but private people can't, I will buy it according to the market price, no need to specialize, your family members like it, you can also buy it." ”

Du You hurriedly gave Zhao Jun a look, and Zhao Jun immediately understood that His Royal Highness the King of Jin hated public weapons for private use the most, and he couldn't make a big taboo, so he hurriedly agreed.

Dugu Qiu also said: "This spring must be guarded by people, and the people can also use it, but it must be protected, and no one is allowed to destroy the pollution at will, does Zhao County Ling understand what I mean?" ”

Jiang is still old and spicy, and he knows that many people don't care about this kind of thing that doesn't cost money, and they will take a bath, do laundry, and even defecate in it, so it must be strictly managed.

Zhao Jun knew this, and immediately bowed down and said, "I understand my humble position!" ”

At this time, the maids brought lunch, and everyone immediately applauded, it turned out to be bamboo rice, which contained fragrant bacon and fresh and delicious cold salad wild vegetables, this meal was indeed simple, but it made everyone appetize, full of praise.

.........

After lunch, everyone set off to see the Danba Waterway, leading the way is Yang Tianhua, who was responsible for dredging the Tianbao Canal, and re-dredging the Zhengguo Canal, and controlling the flood of the Wei River.

Yang Tianhua brought people to inspect the feasibility of restoring the Danba waterway last year, and came to the conclusion that it can be restored.

"At that time, the imperial court thought that Shannan Road could lead Danshui to Shangzhou, from Shangwei Mountain out of Shimen, north to Lantian, because the source of Danshui and the source of Bashui are only seven miles apart, there is a watershed, there is a canyon on one side of the watershed, called Dachangguan, in fact, as long as Danshui and Bashui are led to Dachangguan, a canal will be formed."

"Supervisor Yang's order, isn't Dachang Pass ruined?" Isolated autumn road.

Yang Tianhua nodded, "It's really ruined, there was an earthquake not long after the Danba Road was dredged, Dachang Valley was flooded with rocks, and many officials wrote a book, thinking that this was the will of heaven, asking the Son of Heaven not to go against the sky, Emperor Zhongzong gave up re-dredging, but we have iron and fire thunder, blow up the rocks in Dachang Valley, transport the stones out, and the waterway can be dredged again." ”

The county town to the south of the mountains and mountains, the forest is deep, the distance is the towering blue Qinling Mountains, along the way the birds and flowers, the spring breath is full,

A group of people walked along the official road for about half an hour, and finally came to the source of Bashui, there is a lake covering an area of hundreds of hectares, called Bayuan Lake, countless streams in the Qinling Mountains flow down, converge into a lake here, and then flow north to Chang'an, forming Bashui, the water quality is clear and blue, like a huge sapphire inlaid between the mountains.

There is a canal in the southwest of the lake, the gap is blocked, and this canal is watered by rainwater, forming a long, shallow pond full of aquatic weeds and weeds, which completely covers this canal, and you can't find it without looking closely, and in a few years, this canal will disappear.

"It's the Drain!"

Yang Tianhua pointed to the abandoned water channel: "Danba Road is divided into the northern section and the southern section, the northern section is called the Baqu, the southern section is called the Dan Canal, the Ba Canal is more than 20 miles long, the Dan Canal is about 23 miles long, plus the Dachang Valley, the entire Danba Waterway is more than 50 miles long. ”

"Wait!"

Guo Song interrupted him and asked pretending to be puzzled, "Aren't the two places only seven miles apart?" ”

"Your Highness, seven miles apart is a straight line distance, in fact, the terrain is a little high in the north and low in the south, so it is necessary to take a detour and flatten the terrain in order to facilitate the passage of ships, it took 80,000 people to dig these two canals for two years, but unfortunately it was abandoned not long after."

Only then did everyone understand that it was far more than seven miles, so it was no wonder that hundreds of thousands of dredging were to be invested.

"How much manpower will it take to re-dredge now?" Guo Song asked.

"Your Highness, it is easy to dredge the canal, it is all ready-made, as long as the weeds are cleared and the embankment is strengthened, the key is Dachang Valley, it is really not easy to dredge."

Guo Song immediately said: "Then go to Dachang Valley to have a look!" ”

Everyone came to the Dachang Valley more than ten miles away, which is a canyon about ten miles long, and a section in the middle is blocked by rocks, although for decades, the rocks are overgrown with weeds and vines, and there are a large number of rats, snakes and other small animals living in it.

Guo Song pointed to the pile of rocks with a horsewhip and asked, "How long is this section of the blocked canyon?" ”

Yang Tianhua said: "Your Royal Highness, it is about three or four miles long, if it was dredged in the past, it would take at least 50,000 people to dredge it for three years, but now there is iron fire and thunder, and I think that as long as 30,000 people, it can be dredged in one year." ”

"Is it enough for a year?"

Guo Song was a little surprised and asked: "One year is enough according to the experience of the humble position, and at the same time, a wooden plank road should be built on the cliff of the canyon to facilitate the pulling of fibers." ”

"If you build a plank road, can you form a Danba land route?" Pan Liao asked next to him.

"Back to Pan Xiangguo, that's exactly the case!"

Guo Song was still thinking about the opening time, and he asked again: "Just now you said that it will be completed in one year, is it that in a year, the ships of Bashu will be able to sail directly to Chang'an?" ”

Yang Tianhua hesitated and said, "It can only be said that it is feasible on the map." ”

Guo Song was stunned, and suddenly said with some displeasure: "I said that it was the actual navigation!" ”

Yang Tianhua explained helplessly: "Your Highness, there are still many conditions for navigation, such as the narrow waterway in the valley, you can't take a thousand stone boats, but you can take a trough boat, this is not a problem, the main thing is that the water in autumn and winter is not enough, and it can only be transported to Shangluo County at most, which is the biggest difficulty." ”

Guo Song waved his hand and said: "This problem is easy to solve, build a transit warehouse in Shangluo, transport it to Shangluo County in autumn and winter, and then wait for spring and summer to be transported to Chang'an by tanker. ”

Yang Tianhua thought for a while and said: "The section of water transportation from Hanshui to Danshui is a little inconvenient, but it is already under construction and has taken a bend, and it can be completed in the first half of the year. ”

"This can be discussed with the Firearms Bureau, so that they can develop an iron fire mine that is not afraid of water."

Guo Song's face softened slightly: "I will say hello to the Firearms Bureau, and you will discuss with them yourself." ”

"Obey the order! Then there is the matter of collecting the people and allocating money and grain. ”

Guo Song understood what he meant, Yang Tianhua was just a water supervisor, and many major matters must be decided by the political affairs hall, so he said to Pan Liao and Du You: "You have a good consultation on this matter, take out the detailed rules, and start work as soon as possible!" ”
