"I said long before the southern expedition that the biggest enemy of the Qin army is not the Yue people, but the land itself......"

After a night of heavy rain, the road to the embankment had become potholed and muddy, and Heifu looked worriedly at the dense footprints on it, and the soldiers of the three armies had already rushed to the river before him.

As the first tropical region that the Central Plains people came into contact with, the natural environment of Lingnan is stronger than the northerners imagined.

The dense tropical rainforest once made it difficult for the Qin army, but after two large army marches, the axe splits and burns, and the forests along the communication road are burned a lot.

Dysentery, malaria, scrub worms, these tropical diseases, once caused the first southern expedition to kill the army, but after the previous lesson, Heifu made sufficient sanitary preparations to cross the south, and the epidemic did not hit the army so hard.

Seeing that everyone has gained a firm foothold in Panyu and the colony is developing well, who would have thought that they would once again usher in a strong enemy: a heavy rain, and the ensuing flood season of the Pearl River......

The Pearl River Delta is low-lying and flat, the river network is dense, the summer is rainy, the summer calendar is from March to July for the flood season, the upstream flood swept in, often flooded the people's livestock houses, the local Yue people and sheep department suffered deeply.

But the sheep department has not been relocated, South Vietnam is a good boat, even if Panyu City is flooded, they can sit in a boat, the streets and alleys as a river. As for the fields? There is no need to worry, most of the rice fields of the Yue people are "tidal fields", which are cultivated roughly, and it is purely up to God to eat, because there is no good water conservancy system, and they also need to rely on the annual river tide for irrigation.

However, the severity of the flood is unknown, and every year, half of the tidal fields along the coast will be washed away, and the seedlings will be lost.

Regarding the tides of the rivers and seas, the Yue people had an indifferent attitude, but the Qin army could not let the big water drive straight in.

In the past six months, Heifu ordered the three armies to open up a lot of tuntian, and the Lingnan early rice matured in June and July. It is now the end of May, and seeing that the ears of rice have taken shape, and after harvesting, they can be supplied to the southern expeditionary army and make up for the somewhat tight logistics, how can we sit back and watch the water float away?

Moreover, two years ago, the Central Route Army of the Southern Expedition was caught off guard after being attacked by a large flood, so it had to evacuate Panyu, and was immediately attacked by the South Vietnamese tribes, beaten everywhere, and could only run all the way back to Lingbei.

Having learned the lesson of the last time, as early as March after the end of the rice planting in Tuntian, Heifu ordered tens of thousands of conscripts to build a small embankment in the southwest of Panyu, at least to ensure that the military camps around Panyu would not be flooded.

"If there is a drought, the water will be a boat, and only by taking precautions can we be prepared."

Now, with the flood season just around the corner, it's time to test the effectiveness of the levees.

The car stopped, and Heifu got out of the car to take a look at the embankment, and couldn't help but gasp.

Yushui is divided into three in the southeast of Sihui, the northernmost one flows through the southwest of Panyu City, at the mouth of the river, there were originally many sandbanks formed by the impact of sediment brought by Yushui, but now, there is only a turbid ocean left......

"Good water...... No, it's so big water! ”

"Chang Nan Hou!"

At this time, a gray-haired Qin official came over and waved at Heifu.

"The History of the Guardians."

Heifu is very respectful of this person, this is the famous supervisor Shi Linglu, it is said that he is a disciple of Zheng Guo, a water conservancy expert, during the Qin-Chu War, Linglu had helped Wang Jian repair the barrier to resist the Chu army, at that time Heifu and Zhang Han, or Linglu under the jurisdiction of the workers.

However, cutting off people's heads to make military merits is much faster than burying one's head in civil engineering upgrades. In the past ten years, Linglu seems to have fallen silent, he first worked in Huiji County, and then transferred to Changsha County as the supervisor of the imperial history, connecting the Xiangjiang River and the Pearl River The artificial canal Lingqu is his handwriting!

Half a year ago, Heifu, who intended to build a dam in Panyu to prevent the flood season, used his power as the chief general of the southern expedition to transfer Linglu to Panyu and preside over the construction of this embankment.

After arriving in Panyu, Jianlu inspected the surrounding terrain and planned the most suitable location for the embankment, and connected them with artificial embankments with the terrain of hills, hills, and platforms that protrude along the river.

"It's raining too much."

As the two of them walked on the embankment, Jian Lu said to Heifu: "It has been raining for a day and a night, and the three streams of Yushui have a tendency to merge, and now it is a country, and although the weather is clear, the water level is still soaring, and it is almost not at the foot of the embankment." ”

During the flood season, the entire Yushui coast can be said to be immersed in water, and the trees under the embankment have been flooded to the trunk of the tree.

"Can you hold it?"

Looking at the embankment under his feet, which was too simple compared to later generations, Heifu didn't have much confidence, if he couldn't, he could only move the military camp that had gathered tens of thousands to the north, and at the same time give up the rice fields that had worked hard for half a year.

"I will be able to hold it!"

Jian Lu is not the same, and he is full of confidence in this: "If you still use the earthen embankment in Qiantang County, I am afraid that it will be washed away, but this unique rocky pond in the world is not afraid of floods!" ”

The embankment in Panyu is obviously not the first seawall, and there is a "Qiantang County" in Huiji County, where Jianlu was an official. The reason why this name is taken is because this county is located at the mouth of the Qiantang River, the tide is violent, often drifting no people, livestock, cattle and horses, and washing away the city and houses, so the supervisor summoned the local chiefs, each family pooled money, even hired and levied, digging soil and building ponds, because of the name.

After coming to Panyu, Jian Lu wanted to repeat his old skills, but Heifu thought that the earthen wall might be difficult to resist the tide, so it was better to learn from the successful experience of Li Bing, the Taishou of Shu County, in building Dujiangyan, and put big stones in bamboo cages, leaning on them one by one, and then laying large wooden stakes to make them firm and solid. The stone is like a ladder, obliquely to the river, in order to control the tide.

Jian Lu pointed to the west and said: "Prince, please see, in fact, this Yushui has entered the sea a few miles on the west side, the water potential has been discharged, and it is only the end of the strong crossbow that rushed to Panyu City, in the past, the Yue people let the tide come and go, and now with this stone pond, the water must not cross half a step!" ”

Heifu was a little relieved, but at this moment, the soldiers who had been ordered to patrol the embankment suddenly shouted loudly: "Here comes the water!" ”

However, another flood peak is coming, and in the area where the dam has not yet been built, a large area of rice fields has been flooded, and occasionally the dry fence houses of the Yue people have been completely destroyed, and the flood flow speed is extremely fast, and the river surface is floating with driftwood, the corpses of wild beasts and even people, rushing to the foot of the embankment!

"Junhou, retreat!"

Mulberry was trying to persuade Heifu to leave this dangerous place, and if the levee broke, and the Lord would make any mistake, then they would have no excuse.

Heifu glanced around, and after receiving his order, tens of thousands of soldiers trained in Panyu were led by military officials to the embankment, guarding various positions, carrying bamboo baskets full of pebbles.

As soon as there is a gap, it must be filled immediately, and at this moment, the soldiers of each battalion are quietly waiting for the tide to hit the shore.

He made a decision, summoned Licura, and ordered:

"Erect my Jiaolong and tell the soldiers of the three armies that Changnan Hou is on the embankment! Advance and retreat with them! ”

The herald galloped and spread this word all over the left and right embankments, and cheers were heard everywhere!

The battalions also played their flags one after another, and for a time, the flags were like forests, hunting in the wind, magnificent, and they would be the courage of the three armies, and the black man would take the lead, and the three armies would not be afraid of the turbulent river.

The flood peaks of the Yushui are still advancing towards the dikes from west to east, and Hefu can only stare at them, if they hit the dikes, will the tide recede, or will the dikes be destroyed?

Waves crashing on the shore! The turbid waves hit the rocky pond of the Shaking Sea, shattered, and the splash of water splashed Heifu's face, but his heart was a little calmer, because the embankment under his feet did not move!

Heifu stayed until the evening, even in the second half of the night, with the help of the rising tide and the counter-invasion of the sea, the water level was much higher, but it was blocked by the dike, and even if one or two collapsed, it was filled in time by the officers and soldiers of the three armies.

The most dangerous day passed, and in the next few days, the weather was rainy and sunny, and the river rose and fell. Every day, Hefu visited the levee to check on the situation, but his focus was no longer on the floods, but on observing the order of the battalions ordered to "fight the flood and provide relief."

Several lieutenants under Heifu, Anpu still guarded the three passes, responsible for the transportation of heavy grain in Lingnan, Dongmen Leopard, Gongao, and Xiaotao with 30,000 people, and were sent by Heifu to the upper reaches of Yushui, and Zhao Tuo in Guilin to build a fortress in the plain and attack Xiou. Wu Rui took 5,000 people to Longchuan, Dongjiang, recruited the hornet, and protected the east side of Panyu.

As a result, Panyu was left with a bunch of captains, waving the small flag of the bird, leading a group of recruits sent by Xiao He from Lingbei to practice.

Whether this group of recruits can maintain their composure and how efficient their rotation is when the water hits the embankment can also show how well a unit is trained on weekdays.

Among them, there is a team that is the most orderly and unhurried.

"Go see, who's that?"

A short time later, the herald returned and reported:

"Junhou, don't change Han Xin!"

"Sure enough."

Heifu smiled, since half a year ago, he encouraged Han Xin "A soldier who doesn't want to be a general is not a good soldier", this kid is at ease, he didn't run away at every turn, he trained honestly, Tuntian, and all kinds of training were among the best among the recruits left behind.

However, Xiao He, who stayed in Changsha County, wrote in the spring and recommended Han Xin, praising him as a "national soldier", proficient in the art of war, good at military formation, and very useful......

Heifu said that he knew, but he burned the letter, spring went to summer, and autumn was coming, and Han Xin was still not promoted.

He didn't want Han Xin to feel that the Zhuo Ba appointment from the Marquis of Changnan was all due to Xiao He's recommendation, but he often summoned Han Xin to talk about the art of war with him, and he attached great importance to it, giving him the illusion that "as long as Xianyang agrees to my promotion, the prince will soon use me".

But Han Xin, a person with extremely low self-esteem, self-confidence, and pride, can't maintain his patience for long just by fooling and verbally praising him.

"I've been putting this awl in my pocket for a long time, and if I don't use him again, I'm afraid I won't be able to wait and stand out. However, killing chickens with a slaughtering knife is really a bit extravagant. "He talks about luxury, but Heifu is happy in his heart.

Looking at the receding flood waters and the intact levees, he made up his mind.

"Panyu has been saved, the grain is about to be harvested, the vehicles and ships have been produced, the recruits have been trained, everything is ready, after the flood season, it is the time to march to Xiou and Luoyue!"

"Time is running out, I must end this war before the thirty-seven years come!"

Hefu looked back to the north: "Then, prepare for the next one!" ”
