Yan Xi was about to lead the crowd out of Pingyang County at a predetermined time when he received a strange temporary order.

The Shadow team members who came urgently to deliver information to him used oral instructions to convey the latest order of the "Fuhu Project" headquarters, asking him to leave behind 2,000 cavalry and about 20,000 civilians to lay wooden stakes and fences in the Fen River in the east of Pingyang County, and to stop fishing nets in the river.

Of course, Yan Xi knew that a few fierce people in the front-line command would definitely not be idle and have nothing to do, and wanted to use his brothers to practice fishing in the Fen River in the winter, so there was only one result for such a big formation temporarily, preparing to fish people in the river!

After arranging the affairs of the soldiers and civilians left behind in Pingyang County, Yan Xi took 8,000 cavalry and more than 70,000 people on the road again. They followed the east bank of the Fen River, which had dried up in winter, and slowly and leisurely headed towards Yong'an City upstream.

The tanma between the Fen River and Yang County galloped rapidly, constantly reporting to Zhang Fei the latest movements of the northern barbarians. Zhang Fei led 30,000 soldiers of the Northern Army to abandon Yang County without hesitation, preparing to teach this barbarian cavalry a hard lesson on the side of the Fen River, and then stationed in Pingyang County, and then made the next calculation.

Lurking in the dense forest, the shadow team members on the hill silently watched Yan Xi and Zhang Fei's actions, and from time to time transmitted information signals to their companions in the distance through a concave mirror that could focus light.

The principle of this signal transmission is still Morse code, but the speed of propagation is calculated at the speed of light. Because the concave mirror has a limited concentrating effect, a team member needs to relay every one or two miles, and most of the time it takes time to receive and send this relay repeatedly.

Even so, this method of transmission is much faster than riding a horse, and the effect is more pronounced when the amount of information is less. Now that Zhang Fei has led the army out of the city, the information that the team members need to pass on is nothing more than the route and arrival time of Zhang Fei's army, so the amount of information converted into Morse code is very short, and it can soon be reported to Li Jinwu, who is hiding in a hidden valley between Yangxian and the Fen River.

Li Jinwu hid here with 13,000 elite soldiers, waiting for Zhang Fei to pass by, followed them from behind, intercepted Zhang Feijun's retreat, and forced Zhang Fei to lead the team to cross the Fen River to the west bank.

In five days, they built a dam in the upper reaches of Yong'an on the Fen River, which even Wei Yan could not have discovered. Because at that time, Wei Yan found that after Yong'an was occupied by the Jin troops, he searched downstream along the Fen River, and no one would have thought that Pang Tong chose to build a dam to store water in the upper reaches of Yong'an, ready to take a bath for Zhang Fei.

The remaining two thousand soldiers, of which 1,000 were stationed at Yong'an, and 1,000 were guarding the embankment, and at the same time were tasked with blowing up the embankment. As for Lao Pei and the soldiers of the 1,000 Divine Fire Battalion, they have now arrived at the launch position, waiting for Zhang Fei's troops to fight with Yan Xi's troops, and then drive Zhang Fei's army into the Fen River to swim.

A scout horse from the Northern Army returned to Zhang Fei's team on the march and reported loudly: "General Qiqi, no trace of the enemy has been found within five miles ahead, and the road is clean and smooth!"

Zhang Fei nodded and continued to lead his troops towards the Fen River. 30,000 Northern troops, including 10,000 elite cavalry, 10,000 archers, and 10,000 hand-to-hand combat sword and axe soldiers. Zhang Fei let the cavalry open the way in front, the archers in the middle, and the sword and axe soldiers in the rear, even if they encountered a large-scale interception, if the number of enemies was not far superior to his own, he was confident that he would repel or even defeat the opponent.

In the rear of Zhang Fei's army, there were some carriages painted black, the carriages were in a sealed state, and they didn't know what things were loaded inside, which made the horses pulling the carriages tired and panting.

According to the news sent back by the sentinels, Zhang Fei knew that the barbarian cavalry dismounted because they had to take care of the people on foot, and the marching speed was very slow, so he was not in a hurry to rush to the edge of the Fen River immediately. As long as the barbarian cavalry was reluctant to capture nearly 100,000 people, then Zhang Fei was confident that he would not let them run away. If the barbarian cavalry left the people and fled, then Zhang Fei happened to return to Pingyang County with the people, and he would not pursue Yan Xi, as long as he gave an explanation to the imperial court.

The men and horses of all walks of life walked forward for a while, and when they were already very close to each other, Zhang Fei received a message from the rear of the Tanma, saying that Yang County had suddenly been attacked by enemy troops and had been breached. Zhang Fei then said to Wei Yan with a smile: "It seems that the enemy army attacking Yang County at night is still targeting Yang County Town, and they are now setting off to chase us, I'm afraid it's too late." ”

Wei Yan nodded and said: "As long as we quickly defeat the barbarian cavalry and rescue the people, we can cross to the west bank of the Fen River to occupy a geographical advantage, no matter how many pursuers come behind, I am afraid that we will not be able to attack them halfway!"

Zhang Fei's team then continued towards the Fen River......

The cavalry and people led by Yan Xi have arrived at the designated place, and they are now deliberately scattered into a mess, covering a temporary pontoon bridge not far behind them, and after seeing Zhang Fei's troops coming, they organized the people to quickly flee to the other side of the Fen River, and then sat on the high place on the river bank to watch a good show be staged.

Half an hour later, Zhang Fei's vanguard had already seen the barbarian cavalry and civilians in a panic on the Fenhe beach, and they stopped their march and waited for the arrival of the Chinese army and the rear army.

After a while, Zhang Fei, who was marching in the position of the Chinese army, also rushed to the position five miles away from the river beach, and at this time he happened to see the people on the river beach lining up to pass quickly from the pontoon bridge. He suddenly realized a problem: how could there suddenly be an extra pontoon bridge in this unforeseen place?

Ignoring so much, Zhang Fei immediately ordered the vanguard general to lead 10,000 cavalry to charge towards the barbarian cavalry on the river beach.

A moment later, the 10,000 cavalry of the Northern Army collided with the 8,000 cavalry of Yan Sheng's division. Yan Xi, who had been waiting for this vicious battle for many days, calmly commanded his soldiers to discharge the formation of cavalry attack, and stubbornly withstood the first wave of charges commanded by Wei Yan.

The cavalry of both sides fought to no avail, so they each snatched back the corpses of the soldiers who had died in the battle, and opened up the distance to prepare for another battle. When the cavalry of the two sides were facing each other on the river beach, Zhang Fei suddenly heard an urgent report from Fu Wei of the rear army, saying that a large number of enemy troops had been found in the rear and had cut off the retreat of his army.

Zhang Fei hadn't yet thought of a countermeasure, when suddenly there was a roar of "chirp-chirp" in the sky. When Yan Xi heard this, he immediately ordered his soldiers to turn around and hurry over the pontoon bridge, and after Wei Yan heard this sound, he looked back and saw a group of flying arrows dragging flames flying from a distance, and quickly fell around the dozens of carriages that were tightly guarded by the infantry of the Northern Army.

Zhang Fei shouted "not good" and immediately ordered all the soldiers to charge towards the river beach, and avoid the dark carriages. When the soldier in charge of the chariot saw the rocket coming, he was so frightened that he split the reins of the horse with a knife and drove the horse forward like a desperate charge.

Now that the back road is cut off, and the wagon transporting gunpowder has been hit by rockets, as long as they are not fools, they will choose to charge forward and mix with the barbarian cavalry, which can also reverse the passive situation.

It's a pity that in order to deal with Zhang Fei, Pang Tong and Li Jinwu thought of a lot of tricks to damage it. When Yan Xi organized the cavalry troops of Yan Sheng's division to quickly pass through the middle of the pontoon bridge, he ordered a personal soldier around him to risk death to dismount and light a fire rope. By the time Wei Yan and his cavalry stepped onto the pontoon bridge, the pontoon bridge had already been blown open with a bang.

The wagons used by the Northern Army to transport gunpowder, despite the seals, were made of wood after all. Which rockets fell from the sky shot dozens of gunpowder carriers into hedgehogs, which in a short time burned through the thick walls of the carriages, and a huge barbecue feast began......

The pontoon bridge was bombed, the back road was cut off, and Zhang Fei, who was blackened by the smoke of gunpowder, stood on the river beach at this moment and only had a nest fire and unwillingness in his heart. Until now, he couldn't figure out what kind of weapon Jin Guo used to be able to shoot rockets so far!

However, before he could come back to his senses, an even more terrifying sound came from the upper reaches of the Fen River. Zhang Fei turned his head to look, only to see a murky wall of water roaring down like a galloping horse, and in the blink of an eye, it was about to come to him.
