After returning to the camp, Liu Juntao first asked the generals to return to the army, and let the officers and soldiers of each department rest first, and at nightfall, Liu Juntao summoned Zhou Zongsheng, the general of the Changshui Army, and Hu Dexing, the chief officer of Shandong Town, to the big tent of the Chinese army.

After the two arrived, Liu Juntao directly pointed to a picture on the table and whispered something to the two, and the three of them discussed in the Chinese army's tent for half the night with a slight light.

Early the next morning, Hu Dexing, the chief military officer of Shandong Town, led 500 iron cavalry soldiers to quietly leave and rushed towards the upper reaches of the Yinma River in the west.

At the same time, General Zhou Zongsheng was also secretly rectifying the officers and men of the Changshui Army and preparing to set off.

That night, all the battalions of the Tiance Army were brightly lit, and there was no difference from usual.

The sentry cavalry of the Tatar Department also continued to appear on the north bank of the Yuma River, although they were across the river, but with the help of the bonfires and torches in the camp of the Tiance Army, they could also vaguely see the officers and soldiers of the Tiance Army on duty and on guard.

For two days in a row, there was no movement of more than 100,000 Tiance troops, which made the Tatar Uketu Khan a little uneasy, but the Tatar troops did not have the ability to cross the river and assault, and if the Tiance army did not take the initiative to attack, the Tatar troops could only defend the north bank of the Yuma River and continue to confront each other.

On the third day, the two banks of the Yinma River were cloudy, at this time it was the end of April and the beginning of May, which was equivalent to the June of the later generations, and it was the rainy season on the grassland.

A few days passed, and the heavy rain that lasted for several days finally stopped, and seeing that the Tiance army still had no sign of crossing the river to attack, he was uncertain, so he concentrated all the sheepskin rafts in the army, and dispatched a thousand elites, quietly crossed the Yinma River that night, and rushed towards the camp of the Tiance army.

The elite of this thousand Tatars was very strong, paddling in the river that had become very turbulent, and when crossing the river, more than a dozen people were swept away by the river, but they still rushed towards the camp of the Tiance army, and no one took a step back.

At midnight, the remaining more than 900 Tatar elites finally arrived on the south bank of the Yuma River, leaving 20 people to guard more than 100 sheepskin rafts, and the remaining 900 people packed up their swords and quietly rushed towards the Tiance army camp.

However, when these more than 900 Tatar elites were moving forward, the sentry posts of the Tiance Army, which were invincible in the past, disappeared, and even the bright and dark sentinels around the camp of the Tiance Army were gone, which made the more than 900 Tatar elites who were attacking with all their strength a little apprehensive and uncertain.

It didn't take long for the more than 900 Tatar iron horsemen to touch the camp of the Tiance Army, and saw that there were many bonfires in the camp, and there were even more torches, which lit up all parts of the camp, and the tents and baggage everywhere were clearly visible.

However, only the soldiers and horses of the Tiance Army are missing!

One of the commanders leading the army had a pale face, and there were only two possibilities for the situation in front of him: one was that the Tiance Army secretly withdrew and left, and the other was that there was a trap ahead, as long as they entered, everyone would be dead!

The Tiance Army is now winning successive battles, and will never withdraw for no reason, there must be a trap ahead, as long as you are not an idiot, you can figure it out.

However, if they turn back like this, everyone will be punished by the Great Khan, and even more than 900 people will be beheaded!

Therefore, the commander only thought for a moment, then waved his hand, and together with more than 900 elites behind him, he destroyed a section of the camp wall and entered the large camp in front of him.

"Spread out! Grab a few captives, set another fire, and evacuate while the chaos is in order! ”

The commander gave the order, and the more than 900 people were divided into more than a dozen groups and scattered in the camp, while the commander of the thousand men stayed in place with a dozen people, and if the situation was not right, he might as well withdraw as soon as possible.

Unexpectedly, after a while, the scattered Tatar elites all ran back in a panic, and the centurions led by them all said with gloomy faces: "General! The Tiance Army is gone, this is an empty camp! ”

The commander was also stunned after hearing this, could it be that the Tiance Army really withdrew?

"Quick! Send someone to the surrounding Tiance Army camps to take a look! ”

The commander hurriedly said, and a group of his subordinates scattered again and rushed around, at this time, everyone had subconsciously no longer concealed the sound and traces, but searched between the various camps of the Tiance Army, but did not find a single soldier of the Tiance Army, the nine Tiance Army camps were all empty camps, and hundreds of thousands of Tiance soldiers and horses were missing!

After hearing the news, the elder was taken aback, and hurriedly beckoned his men to return to the south bank of the Yinma River: "Quick! Go back and report the Great Khan! ”

More than 900 Tatar elites rushed to the south bank of the Yuma River in a hurry, and the twenty companions who stayed behind saw everyone so panicked, and thought that the Tiance army was coming.

"Hurry up and get on the raft! The military situation is urgent! ”

When the commander gave an order, everyone did not dare to slack off, and used their strength to eat, and it only took more than half the time to return to the north shore, and reported the news that hundreds of thousands of Tiance troops were missing.

At this time, Xiaolai's face was very ugly, his brows were tightly locked, and he was constantly thinking about all possibilities.

But I never understood why the Tiance Army, which had been advancing all the way in the war, suddenly withdrew, could it be that something major had happened within the Ming Dynasty?

Or, is Liu Juntao secretly arranging tricks?

However, after thinking about it, there was a turbulent Yinma River between the two armies, and he couldn't think of any way for Liu Juntao to make hundreds of thousands of Tiance troops suddenly cross the Yinma River.

And unable to cross the river in a short time, how could Liu Juntao defeat his army of 200,000 iron cavalry?

For a while, he had no clue, so he had no choice but to send more sentry horses out to investigate, and ordered all departments to strengthen their vigilance.

On a high ground on the south bank of the Yuma River, the officers and soldiers of the Tiance Army re-encamped here, and did a good job of camouflage and prevention.

At this time, Liu Juntao was standing in the rain wearing a hat and a robe, looking in the direction of the Yinma River in the north, not knowing what he was thinking.

At this time, Liu Zi'an came over and said: "Duxian, General Hu and General Zhou have already set off with their own troops and horses, looking at this day, it is estimated that the Tatar department is doomed to defeat this time!" ”

Liu Juntao nodded slightly, but sighed and said: "Since ancient times, it is not difficult for Huaxia to defeat the Tartars, but the difficult thing is to wipe them out!" ”

Liu Zi'an said: "Is the governor worried that he will escape by luck, and that the Tatar ministry will make a comeback? ”

Liu Juntao didn't answer, but looked up at the pouring rain and said, "I hope God will open his eyes!" ”

At the same time, Hu Dexing, the chief military officer of Shandong Town, led 500 iron cavalry soldiers all the way west, braving heavy rain and hurrying continuously, and finally arrived at the foot of a mountain a few days later.

It is located in the upper reaches of the Yuma River, where the abundant water flows through the valley of this large mountain.

Seeing this, General Hu Dexing breathed a sigh of relief, waved his hand and said loudly: "Brothers, go!" Let's go up the mountain! ”

Everyone dismounted one after another, followed by Hu Dexing, the chief military officer of Shandong Town, and went up the mountain, and everyone hurried hard in the rain, and it took a full hour to come to a ditch and dam that had been deserted.

This section of the dam was built here by the Ming army during the Yongle period, when there was a Ming army garrison at the foot of the mountain, under the jurisdiction of the Daning Division, this ditch dam is used to prevent mountain floods, snow water, so the Ming army spent a lot of effort on the design, basically according to the terrain, along the natural obstacles will connect some rocks, even so, the strength of the project is still very amazing, it is said that it took thousands of Ming troops a whole year to build.

Of course, these situations were secretly found by Liu Juntao, if it wasn't for a team of sharp whistles who accidentally discovered here, Liu Juntao sent someone to send a letter back to Datong Town, so that the Central Department could urgently check the bottom file information, and really didn't know this story.

And after Liu Juntao figured out these reasons, he led 200,000 Tatar troops to the north bank of the Yinma River, which made Liu Juntao exclaim, "God help me"!

At this time, the team found that the sharp whistle here was also in the ranks, and it had only been more than twenty days since everyone discovered this place, but the scene in front of them was completely different.

At that time, when the sentry team found this place, although it was already the turn of spring and summer, the temperature here was still very low, much colder than the bottom of the mountain, and the soil and rocks under everyone's feet were frozen hard.

Now, more than 20 days later, the temperature here has warmed up, even on the hillside, I don't feel much chill, and even the soil under my feet feels damp and soft.

At this time, General Hu Dexing led 500 iron cavalry soldiers to climb the dam, and couldn't help but exclaim at a glance!

"That's right."

Hu Dexing muttered: "The ice has already broken on the river surface below the mountain, and the snow melt is afraid that it will be a month or two, but on the higher mountains, the sudden melting snow should only reach its peak in the next few days!" ”

Hu Dexing understands that if the temperature is too low in winter and the temperature rises sharply in spring and summer, the glacial snowmelt flood is extremely terrible, and the amount of water in some areas is not under the heavy rain and flood! Due to the difference in altitude, there is a certain temperature difference between the mountains and the mountains, and the melting of ice and snow is carried out quietly, and now this piece of water on the mountain is afraid that it has accumulated for more than 20 days.

Is this still the hillside that the sentry soldiers saw? It's not, it's not! This is simply a plateau lake, and this lake is not static, but flowing. On the higher peaks, there are still torrents rushing down, but fortunately, this canal and dam are not mainly obliterated, but mainly induced, a large amount of stagnant water is discharged, gradually leading to the northeast and then from a tributary into the upper reaches of the Yuma River.

The function of this canal and dam allows the snow melt water to be channeled little by little to the largest river here, the Yuma River, so that the path of the snow melt water flowing into the Yuma River becomes longer, and then flows smoothly downstream, turning harm into benefit!
