On the tenth day of June in the fourth year of the Great Song Dynasty, on the north bank of the Yellow River, 60,000 Song troops lined up neatly. Of course, Taiwei Zhao couldn't let these 60,000 people hear the volume of the voice at the same time, and many commanders and fighters with loud voices repeated Zhao's words through voice retelling. Based on such a way, Zhao Jiaren's speech was not long.

"Comrades, we are all Han Chinese. More than 1,300 years ago, our Han Dynasty blocked the gap in the southward flow after the Yellow River burst. Now, more than 1,300 years later, we want to make history with our own hands. When you are old and sit outside in the sun, your grandson may ask you what you have done in the four years of the Great Song Dynasty. At that time, you can proudly tell them that you were leading the Yellow River north with 100,000 comrades-in-arms at that time. This kind of feat has only happened a few times in China's thousands of years of history! Let's unite and work hard to accomplish this great work! Long live China! Long live the Chinese people! ”

"Long live China! Long live the Chinese people! The whole army chanted this familiar slogan.

Zhao Jiaren did not continue to make any tricks of the whole army shouting "Long live Captain Zhao" and then rebelling together. This trick is a trick that the weak will do, and the next thing to do is not to rebel with enthusiasm, but to bury your head and work diligently to build a dam and repair the embankment. After shouting the slogan, Zhao Jiaren immediately ordered the start of construction. The troops arrived at the designated place first, and if they made a duel and ended up drowning their own troops, it would be a huge joke.

After the various units were in place, some members of the school club under the banner of the Great Song Commando carried out the most dangerous work and continued to shovel the river embankment. The thinner the embankment, the better the effect of explosives. It didn't take long for the embankment to begin to seep water. After the rapid evacuation of the commandos, the demolition team went into action.

The cavalry of the Song army had withdrawn far away, and even so, the loud explosion frightened the Arab horses, who were not very sensitive to sudden sounds. Zhao Jiaren, who was standing on the side of the aqueduct in the north, felt the vibration coming from under his feet, and felt his heart beat wildly.

Looking up, the loess and sediment at the explosion site rose into the sky, as if a huge mushroom cloud had risen. The smoke and dust first cleared, and then a sound like a cow's roar came from afar. And the lower part of the smoke and dust seemed to be pulled by something.

"Come on! Here comes the water! The sharp-eyed soldier was already shouting with trembling voices.

Zhao Jiaren didn't see clearly at first, but only to look intently noticed that there were white waves in the aqueduct. Then the waves approached layer by layer, and rushed down the aqueduct.

"Here comes the water! Here comes the water! We weren't wrong! Ha ha! Hahahaha! Dong Ruhai, who was in charge of the surveying work, laughed loudly, and the laughter was a little crazy, and the surveyors also cheered. It was not only the technicians who cheered, but also the soldiers who watched the situation from above. The voices of tens of thousands of people roared like thunder.

Zhao Jiaren didn't care about the joy of these comrades, what he cared about was how far the water could flow. I saw the river rushing into the dry canal, rolling up the sediment, making the canal in front of me, which is not too wide, look as muddy as the Yellow River in the 21st century. The groom finally quieted down Zhao Jiaren's war horse, Zhao Jiaren took the reins and shouted to Dong Ruhai, who was still laughing: "Let's go, let's walk along the canal." ”

After finishing speaking, Zhao Jiaren stroked the brown war horse with his hand, and felt that the horse was trembling slightly, and it seemed that the violent explosion scared it a lot. At this time, Zhao Jiaren did not dare to ride rashly, but walked forward. Dong Ruhai excitedly followed Zhao Jiaren's side.

The speed of the water is much faster than that of Zhao Jiaren and others walking on two legs. It can be seen that the level of surveyors is very high, and the worst situation did not occur, and the water was flowing rapidly wherever Zhao Jiaren went. After going out for two or three miles, the horses slowly recovered their spirits. Zhao Jiaren and the others rode on horseback, and the speed of travel was much faster. When I came to the end of the ditch that had been dug four or five miles long, I saw that the river had rushed out of the ditch and was rushing along the lowest place according to the gravitational pull.

Seeing that his work had played a role, Dong Ruhai said loudly: "Taiwei, as long as the Yellow River is blocked again, there will definitely be a new river here!" ”

"Hmm." Zhao Jiaren nodded, and he swallowed the words 'maybe it can work' back into his stomach. Until now, the troops have done destructive work, which is relatively easy. This kind of thing can even be done by Du Chong's bastard. The next blockage of the Yellow River is the main event, and whether the Yellow River diversion can succeed this time depends on this part.

With the exception of the units responsible for guarding, all units began construction simultaneously on both sides of the Yellow River. Previously, troops had already laid wooden stakes 30 meters apart from the river bank, and rope nets were tied to the stakes. All the senior commanders, including Zhao Jiaren, took the lead in carrying straw bags filled with dirt and began to fill the river, and they threw these straw bags filled with soil into front of the rope net, which sank, was pushed backwards by the river, and then caught in the rope net. Stabilized.

The water flow on the bank was not large, and two dams were soon built on both sides of the Yellow River. On each side of the Yellow River, there are two railroad tracks with sleepers leading directly from the shore to the dam repair site. On it there are all sorts of heavy supplies running on it. On the first day, with the previous preparations, the dams on both sides soon extended to a position of more than fifty meters into the river.

This dam can only be built day and night. North of the Yellow River, facing the Mongol attack, all carried out by the army. There was no such problem on the south bank of the Yellow River, and the army recruited a large number of people to participate in the construction operation. I saw that the lights on both sides of the Yellow River were bright, and it looked like a galaxy falling from a distance.

On the first day, the Mongol army had not yet reacted. At the rest of the next night, all the armies conveyed the latest news. In the afternoon of the same day, there was an accident in the troops. The newly excavated slopes on both sides of the river have been eroded by the river and have collapsed. The two inspectors accidentally fell into the water, but fortunately, everyone was wearing life jackets and was finally rescued before they died.

"When the new river channel is stabilized, we will definitely organize everyone to go and watch it. Now that the river is unstable and full of dangers, for the sake of everyone's lives, we ask that all troops not be allowed to go to the new river. "Captain Zhao's order was conveyed to the whole army.

On the third day, Mr. Zhao, who had given the order for safe production, went to the river to watch for a while. The ancients said that water drops and stones wear, and Zhao Jiaren himself has seen the small pits under the eaves that were punched out by water. Lao Tzu said, 'The world is weaker than water, and the strong can win'. The river erosion effect on the river channel is endless, and the weak soil layer of the new river channel is soon widened and deepened by the river erosion, and the soil slopes on both sides of the river are hollowed out by the water, and the slightest shock will collapse. The collapsed earthwork was quickly swept away by the river and did not block the river. In two days, the entire river was several meters wider.

When the cavalry led by Zhao Taiwei marched along the south bank of the river, they saw the figure of the Mongolian cavalry on the other side of the river. The two sides looked at each other across the river, and then they both chose to ignore it.

After returning from the tour, Zhao Jiaren received news that the Song army camp north of the new channel of the Yellow River had been tentatively attacked by the Mongols. Regardless of what the Mongols thought at first, their attack was not terminated after being bombarded by the artillery and muskets of the troops in the Song army camp, but they reluctantly chose to retreat after testing all the camps.

Thanks to the previous misjudgment of the Mongol army, the Song army built a large number of camps north of the new river channel and was able to protect the new river channel. There is no way for the Mongol army to get close and do anything.

On the evening of the third day, Zhao Jiaren looked at the newly repaired river embankment. At this time, the embankments on both sides of the river plunged into the Yellow River for more than 300 meters. However, compared with the Yellow River, which is six or seven miles wide, it is nothing at all. But you can already see the appearance of the embankment plunging into the Yellow River.

In three more days, the length of the Yellow River's embankment exceeded 600 meters. According to measurements, the water level on this side of the new embankment has risen by more than a meter, and it is clear that it has begun to have an impact on the Yellow River. Not only has the flow rate of the river between the two embankments increased significantly, but the flow speed of the new channel has also increased significantly.

On June 16, the fourth year of the Great Song Dynasty, it rained, and the river reclamation work did not stop. At this time, two embankments 30 meters apart on both sides of the river bank have been merged into one to form a long embankment with a width of 50 or 60 meters. The causeway was paved with as much dry earth and gravel as possible, and a dozen railroad tracks were laid on this semi-hard ground. Relying on the carts pulled by animal power, the railroad tracks have been used to transport embankment repair materials. So that the construction work can be carried out continuously.

In the afternoon, the cavalry rushed back in the rain. Dong Ruhai, the person in charge of surveying, walked into the big tent wet. When he took off his hat, he revealed a face full of joy.

"How?" Although Zhao Jiaren was asking, there was a smile on his face.

"I told the Taiwei that we marched along the south bank of the New Yellow River, and found that after the initial river water merged with the local small rivers, those southward rivers were blocked by the sediment that washed in, and the Yellow River continued to flow eastward as a whole, and there was no situation where the new Yellow River rushed south and then into the old course of the Yellow River. Tai Lieutenant, we went two hundred miles before, which is really right! Dong Ruhai, an engineering man, said happily.

If it is a civil official, or the kind of person who is proficient in the world, he probably will not take the credit on himself at this time. Because it was Zhao Jiaren who proposed to go out two hundred miles to measure. Dong Ruhai unconsciously equated himself with Zhao Jiaren, which is really the habit of engineering men.

Zhao Jiaren didn't want to be serious with them. When he heard the news, he was very happy. The commanders who remained at the construction site and the comrades of the survey department also had smiles on their faces. Everyone's hard work has finally been proven, which means that the work of repairing the embankment can continue.

The joy of the Song army is the loss of the Mongol army. When Zhao Jiaren and his comrades were smiling, in the Golden Tent of the Mongolian Army in Huaxian County, the faces of the Mongolian generals and the Mongolian Khan Kublai Khan were very gloomy. Up to now, there is only one question in everyone's minds, what should they do if they refuse to rush the camp set up by the Song army north of the Yellow River!
