After arriving at Luohua River, Li Yan rode a horse for a while, saw the location, and ordered the men and horses to start digging. At this time, the weather is cold, the ground is very hard, it is really difficult to dig, but it can't stand the crowd, seven or eight thousand people and horses work together, only five hundred steps long, it is still not too laborious.

Before noon, a large canal with a length of 500 steps and a width of 3 steps was dug, and Li Yan ordered not to dig to the Bahe River first, but to leave it a dozen steps away, and at this time to start building a dam to be able to stop the water.

The troops went to pick up stones, cut wood, canal mud, and worked for a while to build a high dam, and then Li Yan ordered the water to be brought over.

Everything is as estimated at the beginning, the Bahe River flows down the canal, pours into the Luohua River, flows not far away, and is stopped by the high dam, because the dam is very high, so the river water is getting higher and higher, about a zhang.

Li Yan looked at his masterpiece and was very satisfied. After the high dam was built, Li Yan asked Li Dingguo and Sun Chengzu to go downstream separately and ambush the men and horses on both sides of the Luohua River in order to intercept the official army.

Everything is ready, only the east wind is owed, just waiting for Zuo Liangyu to come.

The scouts sent out did not come back, indicating that Zuo Liangyu's men and horses were still far away, Li Yan looked at the direction of Xi'an City, although it was far away from dozens of miles, but if the peasant army attacked the city, there would definitely be fireworks in the city, and there were no fireworks in that direction at this time, indicating that the Zhang Luo coalition army had not yet broken through the city.

When Kankan was approaching dusk, a scout Pegasus returned and reported to Li Yan: "Li Gongzi, here, Zuo Liangyu is here." ”

Li Yan asked, "How far is it from here?" The scout said, "About thirty miles." ”

Li Yan estimated that the left army was thirty miles away from Luohuachuan, and Luohuachuan was more than forty miles away from Xi'an City, that is to say, the left army was nearly eighty miles away from Xi'an City.

If this is the case, then Zuo Liangyu should camp after dark, he must maintain manpower and horsepower, so that the war will start tomorrow, if he does not camp, he will travel overnight, too close to the peasant army, and will be vulnerable to sneak attacks, Zuo Liangyu is a famous general in a hundred battles, of course this is understood.

Li Yan estimated that Zuo Liangyu might camp thirty or forty miles away from Xi'an City, that is, they might be stationed as soon as they crossed the Luohua River.

The only thing to worry about at the moment is whether Zuo Liangyu will pass through the Luohua River before tonight. If they pass by again tomorrow, Li Yan's men and horses will have to wait for a night, so after nightfall, the intercepted water will not flow, what if it freezes?

Li Yan was a little anxious and looked downstream from time to time.

At this time, he was only surrounded by more than 1,000 horses, and the more than 6,000 elite cavalry sent by Zhang Xianzhong and Luo Rucai were already ambushed on both sides of the lower reaches of the Luohua River.

The sky was getting dark, and he hadn't seen the firelight yet, Li Yan was a little anxious, he was afraid that Zuo Liangyu would only fall into the Huachuan River tonight, so his arrangement would be in vain.

The red lady saw his thoughts, knocked her horse forward, came to his side, and said softly: "Don't worry, Zuo Liangyu will come." ”

Li Yan said: "Are you sure? The red lady nodded: "Thousands of people are camped, and they are most afraid of running out of water, and the best water source in this place is undoubtedly the Bahe River, so Zuo Liangyu must be camped next to the Bahe River, and if he wants to get to the Bahe River, he must pass through the Luohua River." ”

Hearing this, Li Yan seemed to have taken a reassuring pill, and smiled sideways at the red lady: "You are still thoughtful." Now, I don't have any doubts. ”

As he was talking, he suddenly saw a fire shining in the downstream direction, and a sentinel came to report: "The fire in the downstream direction is a signal." ”

Li Yan waved his hand: "Open the river." ”

Hundreds of soldiers started to use hooks to hook the stones, wood, river mud and other things that were building the dam, and only a small opening was opened, and the water of the river that was so high that it was like countless wild horses breaking off the reins and breaking the golden locks, roaring downstream. The splash was terrifying in the dark night.

Li Yan and the Red Lady led all the men and horses to kill down the riverbank.

When I got downstream, I saw the fire in the distance, thousands of people and horses fighting together, both sides of the river were full of people, take a closer look, Zuo Liangyu's people and horses have been divided into two halves by the river, can not echo, and the water depth in the Luohua River is several feet, many officers and soldiers with horses were drowned in the river, drifting away along the water.

Li Yan's strategy was a complete success.

As he expected in advance, when Zuo Liangyu rushed to Luohuachuan with his men and horses, it was already dark, Zuo Liangyu knew that forty miles away from here was Xi'an City, he wanted to go all the way and kill the city, but when he saw it again, his men and horses were already very tired and could not immediately enter the battle. Therefore, he decided to camp on the edge of the Bahe River, rest for one night, and wait for the next day to have a full meal before driving to the city of Xi'an to fight a decisive battle with the peasant army.

At that time, Hong Chengchou and himself were caught between him and back, and there was no doubt that he was a thief.

So Zuo Liangyu ordered to rush to Bahe and camp at full speed.

When the army got the order, they hurried non-stop, and when they came to the Luohua River, they saw that it was a ditch that was not wide, and there was not much water, so they pulled a long queue and went down the river, occupying the beach several miles long.

At this time, the ambushed peasant army cavalry saw it clearly, Li Dingguo was on the east bank of the river, Sun Chengzu was on the west bank of the river, and when half of the official army had already crossed the river, Li Dingguo ordered his subordinates: "Light the fire!" ”

The firelight was shining brightly in the dark, Zuo Liangyu was taken aback, and before he could understand, Li Dingguo had already led the cavalry to besiege from behind, and at the same time, on the other side of the river, Sun Chengzu's men and horses also appeared, shouting in unison and charging, and the officers and soldiers rushed to respond to the battle, caught off guard.

The most terrible thing is that there are still many officers, soldiers, and horses in the middle of the river, and these people are blocked by people in front and behind, and they cannot enter or retreat, and they are crowded together in the river.

It was at this time that the water from the upper reaches came down.

It was in the dark, and the water was very scary, and as soon as I heard the sound of water, it was just a blink of an eye, and it rushed to my eyes.

Under the light of the fire, the head of the water as high as one zhang was like countless wild bison, swept everything in the river, and those officers and soldiers shouted to the sky and wanted to rush ashore, but they were crushed in the middle of the river by Li Dingguo and Sun Chengzu, unable to move, and watched the flood rush to their eyes.

Zuo Liangyu had not yet crossed the river, he was in the rear army, at this time when he saw that he was being attacked from front to back, and there was water coming, he knew that it was not good, if he did not break through a gap, his men and horses in the river would all be washed away, so he ordered, and the cavalry on the river beach rushed desperately.

This really worked, many cavalry rushed ashore desperately, and fought with the peasant army, and the men and horses in the middle of the river also hurried ashore, so when the water flowed down, the men and horses in the river were only half washed away.

Zuo Liangyu roughly calculated, there were hundreds of people who were drowned in the water, his eyes were red, and he commanded the men and horses to rush desperately to kill.

On the other hand, the peasant army had been in ambush for a long time, the terrain was very familiar, and the left army had just arrived, and it was in the dark, and it was impossible to distinguish between east, west, north and south, so there was no effective resistance for a while. Quite a few were killed.

However, the most unfavorable thing is that he was separated from the people and horses on both sides of the river, all fighting against the water, surrounded by people in the center, and he was about to be forced down the river.

Under this unfavorable situation, Zuo Liangyu showed his true qualities as a fierce general, and he ordered his own banner to be erected, and torches were tied to the top of the flagpole so that all the troops could see it. At the same time, he sent his own soldiers to shout together: "The left general soldier has an order, kill the thief desperately, and those who escape from the battle will be beheaded immediately." ”

In this way, not only the officers and soldiers saw Zuo Liangyu, but also the peasant army, Li Dingguo picked off a partial general with a spear, and was killing hard, hearing the officers and soldiers shouting together, looking up, and seeing a big flag, white satin on a black background, there is a big red sun in the middle, and there is a big left character embroidered in the red sun.

No need to ask, it must be Zuo Liangyu.

Li Dingguo was very meritorious, and he didn't rush into the city gate in Xi'an City yesterday, and was almost trapped in the suspension bridge, and he was holding back a breath of fire in his heart.
