For a whole month, Chang'an City lost many colors. During the state mourning, everything came to an end. All counties in the world follow it together.

The princes stayed in Chang'an and could not return for a long time, although they were anxious, but there was nothing to think about.

Heavy rain becomes a disaster, and it eventually becomes a disaster. Rivers and lakes overflowed, embankments burst everywhere, a large number of fertile fields were flooded, and people began to be dispersed.

This is a precursor to chaos! At this critical moment, the emperor, who had not yet removed his mourning clothes, was so anxious that he convened the relevant ministers several times a day to discuss how to deal with it, but there was no good solution.

The horses rushing from Chang'an City to the Quartet were as eager as meteors, bringing the emperor's most severe edicts to the magistrates in various places. His Majesty the Emperor has issued a death order, and he must do his best to preserve the autumn harvest of the remaining fertile fields this season, no matter what method is used!

Above the court, the emperor stared at the bloodshot eyes, loudly scolded the officials of the Shaofu, sent so many officials to supervise the disaster resistance, and requisitioned a large number of laborers, but with little effect, are they all a bunch of waste?

Just a few days ago, finally, even the Great Plains of Guanzhong was in a hurry. This land of abundance, the great granary of the Empire, has been seriously threatened.

Guanzhong left Han Valley, right Longshu, fertile thousands of miles, rich accumulation, terrain shape, rich products, is the most important grain production area of the Han Dynasty.

Emperor Gaozu and King Xiang fought for the world, and they were defeated repeatedly, and an important reason for the final victory was that there was a steady stream of logistical supplies. The main source of grain and grass for soldiers and horses was Xiao He, who presided over the overall situation in the rear, and made full use of the rich accumulation of the Guanzhong Plain.

This main granary must not be missed, otherwise it is really possible to shake the national capital because of the failure of the harvest. Especially at such a critical moment as the imminent full-scale war with the Xiongnu this year.

The situation in the upper reaches of the Wei River is already very serious, and if we do not come up with a good way as soon as possible, once there is a big breach, which runs through the nearby Han River and Luo River, causing a full-scale flood, then the entire Guanzhong Plain will be completely destroyed.

As soon as Empress Dowager Dou's funeral was completed, the emperor who returned to Weiyang Palace from Baling didn't even have time to rest, so he listened to the urgent report of the Shaofu officials.

Looking at the continuous rain outside the main hall, thunderbolts flashed from time to time, and the people who were shocked panicked. Liu Che saw that the officials who were reprimanded by him in a hurry all lowered their heads and remained silent. He sighed and forced himself to calm down.

I can't complain about them, natural disasters are like this, and people have done their best. If it weren't for the concerted efforts of the whole population to fight the disaster, the damage caused by the rain that has not stopped since the beginning of autumn is unimaginable.

Fortunately, the ships that Yuan Zhaoren had built with all his might in advance had played a huge role in these days. Not only transported a large number of supplies, but also saved many lives, the most effective thing is that at the critical time, many ships loaded with stones and debris, directly sank into the river, blocking a lot of critical dam failures, preventing the collapse of the river embankment in a large area.

This is a matter of immeasurable merit, and it has provided great help to the imperial court in disaster relief. The people of the government and the opposition all admired the role played by these ships from Changle Plateau and the planning of the young marquis.

However, the form of the upper reaches of the Wei River has reached a very dangerous point a few days ago, and relying on manpower will not help at all. In order to prevent the occurrence of the catastrophe of the Guanzhong Plain, after discussion with the court, the best way is to take the initiative to find the flood discharge area, and manpower to dig the embankment and discharge the flood, so as to tide over the difficulties at an acceptable price.

Equally critical is the Wei River, the Yellow River. The Yellow River passes through the Loess Plateau and gorges into the lower plains, and the river is mixed with a large amount of sediment, so it often floods during the rainy season.

Since the Yellow River broke once from the boundary of Dunqiu three years ago, it is more likely to flood in the middle and lower reaches, and there have been many breaches, and the flooding rivers in Puyang and Juye have gone straight down to Huaisi, and the disasters have spread all over the 16 counties, and the lives have been devastated, so that this area has almost no harvest for several years.

In the autumn of this year, it was even more serious, and after receiving an urgent report from the local officials, the emperor had sent three envoys in succession to levy a large number of civil servants and prisoners to fill the gaps. However, nearly 100,000 people have repaired and increased the embankment, but it is still difficult to stop the raging floods.

In such a chaotic situation, the court council discussed, and the ministers were unanimous, but they did not pay good attention. Because, there are many things, everyone knows it, looking at the prime minister with a gloomy face, some words came to his mouth and swallowed again.

Yuan Zhao hurried back from the upper reaches of the Wei River, and he asked for his own life. The Weihe embankment must not be lost! He knew better than anyone what kind of human tragedy would happen after the Great Flood. In the past and present lives, there are too many things that I have seen and heard.

After bidding farewell to Empress Dowager Dou and returning to An, for more than ten days, Yuan Zhao took over this important responsibility, guarding the Weihe River and not leaving the front line for half a step.

Hundreds of newly-built wooden boats, from Changle Plateau upstream, shirtless men, brave the wind and rain, generous and heroic! Many of them were members of the former Liuyun Gang, and in the old days, they were just mixed in the market, and they never knew what the meaning of life was.

In the more than four years of Changle Plateau, everyone has changed dramatically. Some of them joined the Black Eagle Army and experienced the glory and blood of the Huns in the first battle. Some use their own craftsmanship to join various workshops in Changle Yuan. And these men, who grew up in the southern waters, joined the dockyard and transport fleet.

Everyone's path is different. Although some will shine brightly, and some will be obscure, they are destined to no longer have the mediocrity of flies and dogs. And these were all brought to them by the little marquis.

The brand-new wooden boat, full of rocks and bags of mud and sand, felt a little distressing and pity, but it was nothing compared to the loss and lives that were recovered.

The sturdy man scuttled through the bottom of the heavily loaded ship and jumped quickly onto the receiving ship. Wooden ships began to sink, clogging up the breach, temporarily slowing down the turbulent current. The waiting men and laborers rushed up to fill in the soil as fast as they could, and closed the gap.

It worked, and although the rain was still falling and the river was still roaring, people's hearts were gradually calming down. Looking at the thin figure covered in mud and water, who has been commanding by his side, everyone is full of reverence in their hearts!

The Wei River is safe for the time being, but the danger remains. Tens of thousands of people have been guarding here, of course, not a solution. According to the direction of the terrain, Yuan Zhao drew three lines on the sketch.

The county officials around him were all shocked after listening to his explanation. This little marquis's hand is too big!

Yuan Zhao's method is to open a canal! Instead of aimlessly digging embankments and discharging floods in an emergency, it is better to take advantage of the current manpower and material resources to plan early. As long as the rainy season has not passed, the Wei River will break sooner or later. The so-called blockage is not as good as sparse, this is the truth that has been known since the time of Dayu's water control, is it still only stuck to blocking!

With the water of the Wei River as the source, three important canals were first opened, which went directly into the vast and fertile fields of the Hanzhong Plain, and they could dig as far as they could. Divert drainage during flooding and divert water for irrigation during drought, killing two birds with one stone, why not?

Changle Hou once presided over the digging of a dragon head canal, which is in the west of Chang'an City, which is something that everyone knows. The tremendous role played by that canal is obvious to all. Since there is such a precedent that can effectively avoid disasters in the present and will produce great benefits in the future, the governors of several counties have discussed it a little, so let's do it!

This is to defend their homeland, and under the mobilization, everyone is fighting bravely. Moreover, there is the magic of the little marquis to help!

Yes, Changle Hou performed another miracle! This is what tens of thousands of people have seen with their own eyes, and they have seen it really. He turned the churned dirt into a solid brick and stone!

Taking advantage of the efforts of three days of rain, three long canals, separated by dozens of miles, like long dragons, meander along the north bank of the Wei River. People who are very excited are full of energy, and they are full of energy, and they are all in one go!

Yuan Zhao stood on a high place, with the turbulent Wei River behind him, looking at the long canal in the distance, and his heart was very satisfied. The power of the working people is infinite, as long as the heart thinks in one place and the strength is in one place, any kind of miracle can be created for you.

Compared with this spirit, the rough cement that I made improvised is not worth mentioning. The production of cement is very simple, and I still remember the approximate formula ratio, and after two or three trials, although the quality of the cement made is far worse than that of later generations, it is much stronger than the rammed earth of this era.

Although he was not very satisfied with the effect of this so-called "cement", in the eyes of the people around him, the gaze that looked at him was already full of admiration.

The white-haired Hanzhong was too guarded, and he didn't care about his legs and feet, so he personally jumped into the channel that had been dug up, dug hard with his hands, stepped on it with his feet, and was still not at ease, so he pulled out the knife in his entourage's hand and slashed it a few times. The surface of the concrete-covered canal is as hard as iron and will not crack at all.

"Changle Hou, what a god! The old decay has lived for more than fifty years, such a miracle is unheard of! Seeing it today can be regarded as an eye-opener. With this means, for the benefit of the common people, it is really my luck for the Han and the blessing of the community! ”

In the same feelings of everyone, Yuan Zhao saw sincere gratitude in their eyes. I couldn't help but feel very ashamed in my heart, I should have thought of using this method to strengthen the river embankment and build water conservancy. However, floating in miscellaneous matters, these major events of the country's people's livelihood that should really be concerned about have been neglected. If it weren't for the critical water this time, he would not have thought of such a method.

Therefore, on the way back to Chang'an after receiving the emperor's edict, he had already prepared a recital, ready to play the emperor, re-strengthen the embankments in the major sections of the world's major rivers, and at the same time open up channels and build water conservancy, so as to make real use of these rivers to harm and benefit the common people.

However, he didn't expect that at this court meeting, a big battle kicked off again, and the battle of life and death was about to begin!
