At the beginning of 216 BC, Fusu completed all preparations for the expedition to South Vietnam, and nearly 200,000 Qin troops were ready to attack, waiting for the order to attack at any time!

At the beginning of March, when the weather gradually warmed up, Fusu promoted Cao Shen to the rank of captain, and commanded 50,000 Qin troops to stay in Minnan County, and cooperated with Han Anguo, who guarded Minzhong County, to closely monitor the situation in the north! He led 150,000 Qin troops to quickly turn southwest, approaching the front line of Wuling, to meet Shi Lu and Tu Sui's troops!

Lingnan, the land of Baiyue in ancient times, was the place where the Baiyue people lived, and at the end of the Qin Dynasty, it was the jurisdiction of the Nanyue Kingdom. The so-called Lingnan refers to the south of the five mountains, which are composed of five mountains: Yuecheng Ridge, Du Pang Ridge, Mengzhu Ridge, Qitian Ridge and Big Gray Ridge. It is generally distributed in the eastern part of Guangxi to the eastern part of Guangdong and the junction of Hunan and Jiangxi provinces. It is the largest transverse tectonic belt mountain range in the south of the Yangtze River in China, and is the watershed of the two major river basins of the Yangtze River and the Pearl River. For a long time, it was a natural barrier, and the Nanling Mountains hindered the transportation and economic ties between the Lingnan region and the Central Plains, making the economy and culture of the Lingnan region far inferior to that of the Central Plains......

However, at present, there are hundreds of thousands of mighty Qin troops marching on this barbarian land! On this new Chi Road, which was built by Shi Lu and Tu Sui, there are strange mountains and strange rocks, deep forests and dense grasses, and flourishing flowers, but there is also a unique scene!

Fusu beckoned to his side, and a soldier of the Qin army quickly approached him: "Your Majesty, what are your orders?"

"How far is it from General Shi Lu and General Tu Sui's camp?" Fusu is a little tired from walking!

"It's not too far, there are still more than ten miles, and you should be able to get to Xing'an Fort before the sun sets!" This is a post soldier deployed along the Southern Road!

"Hung Ann Fort?" Fusu was a little strange: "There are also such decent place names in the South Vietnamese region?"

The post soldier smiled: "Back to the king, of course not!" Because this vicinity is the last flat place before our army enters Lingnan, after our army built a fort here as an advance base, in order to seek good fortune in the south, so it took such an auspicious name!"

"I see!" Everyone laughed!

The crowd laughed as they walked, and walked a few miles forward. Suddenly, the post soldier's eyes were sharp, and he hurriedly said: "Your Excellency, please look, there is an army in front of you, it must be General Shi and General Tu who are here!"

Fusu hurriedly built a pergola and looked south, and sure enough, where the smoke and dust were billowing, a military horse galloped over. Where the military flag flies, the two black characters of "Tu" and "History" of Douda are fiercely displayed in the wind!

Fusu laughed and said, "Sure enough, it's General Shi and General Tu!" Drive!" Fusu gently urged the war horse, and the white horse neighed and galloped to catch up. The generals behind him also whipped their horses and followed closely behind!

Shi Lu and Tu Sui saw Fusu riding their horses from a distance, and hurriedly shouted, stopped the army, and then flew off their horses and bowed to the ground: "The last general Shi Lu greets the king!"

Fusu also hurriedly reined in the war horse, jumped down, and stretched out his hand with a laugh from a distance: "Two generals, please, I haven't seen you for more than a year, it's hard work." Great work!" Then pick them up!

Shi Lu said with a smile: "Although the ministers are in the south, I heard that the king has frequent good news in the southeast, I am really envious and admired!" Fusu laughed and said, "What a small victory! However, the two generals attacked all the way south. Not only to open roads in the mountains and build bridges in the water, but also to sweep the wanderers along the way. It's quite rare!"

Tu Sui smiled: "The king is too polite! The two of us encountered stragglers along the way, and they were crushed at the first blow, and there was no obstacle at all, and we were only busy building roads along the way. How can there be hard work! It's really not as hard as the king's effort to charge into battle and destroy the enemy country!"

Fusu shook his head and smiled: "Alas, this is a bad word! The two of you are also a rare achievement in opening roads in the mountains and building bridges in the water, if it weren't for the southern gallop road you built. I'm afraid I'm still slowly hurrying between the big and small mountains!" Hahaha!" The generals laughed.

Seeing that Fusu was still here, Ren Huan reminded with a smile: "Your Majesty, the sergeants have been on the road for days and are very tired, so let's enter Xing'an Fort and talk about it when we are full!"

Shi Lu patted his head and said with a smile: "Yes, yes, yes!" Your Majesty, please!" Everyone was very excited to reunite after a long absence, and they rushed to Xing'an with laughter all the way!

But half an hour, far away, a huge fortress appeared in front of everyone: the length and width are more than four miles, the fortress wall is as high as more than five zhang high, the city head is lined with armor, bows and crossbows are dense, in the reflection of the sunset, it is really like a majestic behemoth lying in front of the generals!

"What a majestic city!" Fusu couldn't help but admire: "I don't know who made it?"

Tu Sui said with a smile: "The last general is a rough one, and he doesn't know anything about building cities and roads, these are all arranged by General Shi!" He's such an engineering wizard, it's a miracle that he built such a big military fort in just two months!"

Fusu said with a smile: "Benjun has long known that it must be the handiwork of General Shi, and in the world, General Shi's engineering can be described as unparalleled in the world!" Shi Lu hurriedly said: "The king has won the award, if it weren't for General Tu urging 100,000 soldiers to step up construction day and night, how could it be so fast!"

Fusu nodded and said, "It seems that General Shi and General Tu have cooperated well!" I'm worried that the two of you will not get along!" Tu Sui smiled and said: "Although the last general is a rough man, he admires the ability the most, no, for more than a year, I have been commanded by General Shi to turn around!" Hahaha!" The generals burst into laughter again!

After entering Xing'an Fort, Fusu sat in the handsome position, and the generals sat on the left and right, and then a military kitchen brought up a plate of barbecue. Smelling this tempting aroma, Fusu nodded and said excitedly: "Not bad, not bad!" This is the smell of roe deer!"

Tu Sui smiled and said: "Yes, the king is on an expedition, but there is nothing to entertain in the army, so the last general took people to the surrounding mountains and forests early in the morning to fight some pheasants, hares or something to talk about the heart!"

Fusu smiled: "Thank you, thank you!" Everyone, don't let down General Tu's good intentions, please!" The generals hurried for days, and a bird had already faded out of their mouths, and when they heard the words, they hurriedly worked hard, each holding two daggers and cutting them at the barbecue in front of them.

Soon. Everyone is finally full of food and drink! Fusu smiled with satisfaction: "I've been on the road for more than a month, and I haven't been so happy for a long time!" General Tu and General Shi, you will tell Ben Jun about the recent military situation!"

Tu Sui looked at Shi Lu, and Shi Lu hurriedly said: "You have worked hard from afar, why don't you take a rest first and talk about it tomorrow?" Fusu shook his head and said, "Benjun is an urgent child, I don't understand clearly, I can't sleep tonight!"

Shi Lu smiled, and had no choice but to say, "Then the general will obey his fate!" Since the end of the previous year, after separating from the king, General Tu and I divided our troops into five ways. Begin to advance to the front line of Wuling! Due to the small number of tribes outside the Wuling Mountains of Nanyue and their weak combat strength, they did not cause much trouble to our army! It's just that the closer you get to the first line of Wuling, the more rugged and rugged it becomes, just to build the road for the army to go south and build forts all the way, it has consumed at least 300,000 of my southern expeditionary army so far!

Moreover, as we approach Wuling, it becomes more and more difficult to transfer grain and grass! At present, our army's grain and grass are basically sent from the north by land, however, the jungle is dense, the mountains are high and the water is far away. Although five major roads to the south have been built along the way, the logistical support of our army is still extremely difficult. The main army of 180,000 people under the command of General Tu and I is better, after all, the southern gallop road is fairly well built. If there is no large-scale battle, the grain and grass will be sufficient. It's just that the rest of the four routes have only 30,000 troops and horses each. The roads built are also relatively poor, and the supply capacity is much worse, and the closer you get to Wuling, the more difficult it becomes. I am afraid that if we do not solve the problem of food supply, our main force will barely be able to go deep into the south of the five mountains to fight for a period of time. But the remaining four roads of more than 100,000 people can only play a little blockade role north of Wuling!"

Fusu was taken aback when he heard this: "So difficult?" Shi Lu nodded with a worried face.

Qiang Kui said: "Your Majesty, since the rest of the four route armies are difficult to supply food and grass, it is better to transfer all of them to the vicinity of the southern Chidao and join forces to march west!" Fusu has not yet replied. Shi Lu said: "This is inappropriate! The current supply of 180,000 troops in the southern gallop is already a little stretched, and now with the addition of 150,000 jun, although the logistics and transportation forces have been relatively increased, the supply capacity of the southern gallop has reached its peak! If we withdraw the remaining four roads to the vicinity, I am afraid that the entire army will not be able to meet even the basic food and clothing, and what are you talking about fighting in the south!"

Fusu frowned for a while, gently knocked the case in front of him with his hand, and said in a deep voice: "General Shi, with the current transportation capacity of the southern galloping road, how many thousands of troops can be supplied to the south to Wuling?" How long can it last in the south of the Five Ridges?"

Shi Lu lowered his head and thought for a while: "The mountains on the first line of the Five Ridges overlap, and it will inevitably be more difficult to replenish after the Five Ridges!" The minister estimated that although our army had already built five channels in the Five Mountains, with the supply capacity of these channels and the actual situation of the southern galloping road, I am afraid that we could only maintain an army of 200,000 for no more than three months, and after a long time, the grain and grass would be exhausted! If you can't win in the short term, you will definitely retreat!"

"Three months!" When everyone heard this, they looked at each other: "It took more than four months for a single Minyue to fight, and there were nearly 200,000 troops in South Vietnam, coupled with the complicated geographical situation, it was impossible to win in three months!"

Ren Huan thought for a while and asked, "General Shi, if you open another one or two gallop roads, do you think the supply situation will be resolved?" Shi Lu shook his head and said: "Not only will it take at least 200,000 troops for a year and a half to open a new gallop road, but also the number of people who have been levied to transport grain for our southern army has exceeded one million, and it is absolutely impossible to increase it, so no matter how many gallop roads you drive, you will be trapped by the stubborn disease of too far and the danger of Wuling, and our army's transportation capacity can only be slightly improved, but it will only treat the symptoms and not the root cause, and cannot solve the fundamental problem!" Everyone was in a dilemma for a while!

Fusu also frowned and began to think: "It seems that if the problem of grain and grass supply is not solved at present, the conquest of Nanyue can only be an empty word!" But did this grain and grass fall from the sky? I still have to ship them from the north one by one!" Suddenly, Fusu suddenly remembered: "Lingqu! That's right, Lingqu! How did I forget this!"

Hurriedly shouted: "General Shi, can there be a marching sand table in the nearby geography?" Shi Lu was stunned for a moment and said, "Yes!"

"Get it quickly!" Fusu is a little impatient!

After a while, four strong Qin Army Men walked in carrying a huge sand table and gently put it down.

Fu Su hurriedly stepped into the handsome position, and before coming to the sand table, he couldn't help but fall into deep thought, and after a while, he finally connected the vague memory of Lingqu Land in his head with the actual geography.

"Great, there you have it!" Fusu's face is happy!

Shi Lu was stunned. Said hurriedly: "Your Majesty, will the plan be released?"

Fu Su said with a smile: "At present, my Bashu's grain can only be transported out of Hanzhong first and then transported by the southern Chidao and the remaining four roads that have just been built. So, there's no other way around!

Please see: There is a big river called the Pearl River in the territory of Nanyue, and one of its tributaries, Lishui, is not far south of Xing'an Fort, while not far to the north is Xiangshui, a tributary of the Yangtze River, if we open a canal between Xiangshui and Lishui. Then the grain of Bashu can enter the Yangtze River by waterway, and then enter its tributary Xiangjiang River, and then enter the Lishui and Pearl rivers through this canal, and reach any corner of Nanyue. In this way, with the help of the advantages of large carrying capacity and more convenient water transportation, our army's grain and grass supply will inevitably be solved in one fell swoop!"

The generals were a little stunned when they heard this, obviously they had not yet recovered from Fusu's bold idea. Shi Lu suddenly laughed and said, "Wonderful, wonderful! This idea of the king can really solve the problem of food and grass supply for our army in one fell swoop! The distance between Xiangshui and Lishui is no more than ten miles at most, if we can really use a canal to connect it, not only will our army's grain and grass not have to worry about it from now on, but it will be too beneficial for our Qin State to operate the south of the Five Mountains!"

Ren Huan nodded and said, "Yes." In this way, there will be a convenient passage between the south of the Five Mountains and the Central Plains, and it will be more convenient for the culture and etiquette of the Central Plains to be introduced to South Vietnam!"

Suddenly, Ren Huan remembered. Shaking his head, he said, "No! Not true!" Fusu was taken aback and said, "What's wrong?"

Ren Huan said with a solemn face: "Look at this terrain, it is within ten miles of Xiangshui and Lishui. The terrain decreases sharply from north to south, and I am afraid that the difference is at least more than 100 zhang. In this way, even if a canal is opened, the water will be turbulent like a tide, and it will be impossible to sail at all!"

Fusu smiled when he heard this: "It's very simple. It's not hard to solve! Master Shi, can you imagine it?" In the history of the Ling Canal, Shi Lu was the first to put forward the idea and presided over the construction of the canal, as long as it was mentioned slightly. Shi Lu will definitely figure it out!

Sure enough, Shi Luchu was a little confused, and after staring at the sand table for a long time, he suddenly said with joy: "There is!" You can find a way to lengthen the length of this canal! For example, the canal was built straight for about ten miles, so it was indeed impossible to control such a turbulent current that could not be navigated. However, we can build the canal in such a way that the greatly increased curves and lengths will inevitably slow down the turbulent currents to suit navigation! Of course, there are a lot of other engineering considerations involved, but I don't think it's too much of a problem!"

"Wonderful! What General Shi thinks is exactly the same as Benjun, so the matter of building this canal will be handed over to General Shi! It's really a success, and General Shi will leave a big mark in history after the straight!" Fusu is just plagiarizing the ideas of his ancestors, but he doesn't dare to talk about it in depth, otherwise he will have to show his stuffing!

Shi Lu was also very excited when he thought about it, and hurriedly said: "My subordinates obey the order, and they will definitely live up to their trust and build this river!"

Fusu smiled: "In addition, for the sake of remembering, how about calling this canal 'Spirit Canal'?" However, General Shi, if you want, it is okay to be named 'Shi Luqu', but on the contrary, there is also a Zheng Guoqu in my Qin State Pass!"

Shi Lu hurriedly said: "No, no, just call Lingqu, don't you tell Shi Luqu to kill me!" The generals laughed when they heard this!

Soon, under the order of General Fusu, Li Xin led 50,000 Qin troops to march south, set up camp next to Lishui, and guarded the South Vietnamese army in the direction of Guilin across the Yuecheng Ridge to prevent the enemy army in Fujian and Vietnam from coming to attack after hearing the news of the Qin army's construction of the Ling Canal! And Shi Lu led the main force of 250,000 people to start the construction of the Spirit Canal in full swing!

On the side of the riverbed, Fusu and Shi Lu were standing on a high place and looking down.

On the construction site, more than 100,000 Qin Jun on the morning shift were sweating like rain on the construction site. Since it was the height of summer and the weather was hot, many people went into battle shirtless, and some even wore only a small pair of calf-nosed pants, working hard in the mud!

Fusu sighed in his heart: "This is really a powerful iron-blooded force, elite, brave, fearless, hard-working, disciplined, this army has almost no shortcomings, it is really rare!" I hope that history can help me to make this real iron army bloom and make the world be shocked by it!"

Fusu turned to Shi Lu: "General Shi, how is Lingqu progressing now?"

Shi Lu said with great interest: "The progress is very fast, half of the project has been completed in just three months, it is worthy of an invincible army that sweeps the world, amazing!" At first, I thought it would take a year to finish, but now I think it's half a year!"

Fusu also smiled with satisfaction: "By the way, although Benjun proposed the idea of Lingqu, he is not proficient in actual engineering, and there are many local projects that Benjun can't understand!"

Shi Lu said with a smile: "Now that the project has just taken shape, it is normal for you to not understand it!" I'll explain it to you!" Shi Lu pointed to the distance and said: "The distance between Xiangshui and Lishui is less than ten miles, after the minister designed it to be circling, the river channel was extended to sixty-six miles, and the original surging Xiangjiang River water potential will be greatly slowed down after such a long river and hundreds of bends, and the minister has calculated that it should be completely possible to sail!" However, in order to further balance the water level and control the flood during the period, many auxiliary works are needed, such as: large and small balances, ploughshares, north-south canals, drainage balances, steep gates, etc., to maintain the water level balance, prevent floods, protect the spiritual canal, etc. Once this spiritual canal is fully completed, the minister can guarantee that the Bashu grain ship can start from the Yangtze River and go down the river to the hinterland of South Vietnam, and our army's military rations will no longer have to worry about it!"

Fusu was overjoyed and said, "Isn't there any difficulty?" Shi Lu shook his head and said proudly and confidently: "No! The minister can not only guarantee that the spiritual canal will be completed within half a year, but also ensure that the spiritual canal can be used by my Great Qin for thousands of years without being destroyed!"

Fusu was stunned, stroked his palms and laughed: "This gentleman has Shi Qing's help, it is really like a gift from heaven, and the sky treats me well!" Shi Lu said a little angrily when he heard this: "If Shi Mou is not supported by the king, he will only be a small official of the Shaofu at present, how dare he be so praised by the king!"

Fusu smiled: "Why should Shi Qing be too humble! As long as we wait for the three armies to work together, these thousands of miles of rivers and mountains will definitely be in my hands, and our Qin army will also create a prominent myth that has been passed down through the ages! Shi Qing, maybe a thousand years from now, our children and grandchildren will talk about our achievements today, so that our current hard work will be worth it!"

Shi Lu is also a young and vigorous person, thinking of this glory, he can't help but be stupid for a while!
