In the darkness of the night, as the place where the two armies fought was in flames, the rest of the surrounding area became darker comparatively. In this situation where the view is not very good, on the surface of the river where Luoshui and Yishui flow quietly, simple rafts quietly slide down one after another, as if pieces of fallen leaves are gently floating on the water.

Luoshui and Yishui were both big rivers at this time, and it was not like in later generations, and the water level had been greatly reduced. Especially in the summer, the river is much wider due to the large increase in the amount of water coming from the upper reaches.

At first, these rafts were almost clinging to the bank of the river on the other side away from the battlefield, and in this way they quietly slid down to the middle of the Huangfu Zhen camp, just bypassing the most heavily defended place at the front.

"Get ready, let's do it later!" Seeing that it was already a few hundred meters away from the place where the two sides were fighting, the general of the Tang Army, who was in charge of leading the army, commanded in a low voice.

Soon, these small rafts slowly approached the Huangfu Zhen's camp.

Since all the attention of the Yan army was attracted by the fierce battle head-on at this time, no one noticed that there were some inconspicuous things quietly approaching them on the dark river outside the camp.

On the shore, in the camp of the emperor's real man, the tents were one after another. After all, there are 30,000 troops here, not to mention the places where the soldiers live and rest, or the tents where the baggage and miscellaneous items are kept.

Since Huangfu really put the focus of defense in the front, these tents are naturally relatively far behind.

Although it is said that there is a big battle ahead, it is impossible for all the people in the large camp to throw themselves into the front at once. Therefore, there are still people patrolling the camp, and more people are preparing. After all, it may be your turn to go to war next.

"Hey, what do you think that's that?" There was a small group of Yan soldiers patrolling along the river, and suddenly a soldier glanced at the river and couldn't help but be surprised.

Hearing his words, the others also looked over, and indeed, on the dark surface of the river in the distance, a small ball of light suddenly flashed at this time, as if it was a little ghost fire.

"That's ......!" Wu Chang, who took the lead, took a closer look, and when he was puzzled, he suddenly saw more and more light clusters slowly appearing on the surface of the river, as if they were dotted with stars, and the entire river surface suddenly became much brighter because of these light clusters.

Under the illumination of these light clusters, I only saw that many small rafts suddenly appeared on the surface of the river, and on them were Tang soldiers wearing armor. And those sparkling fires were the bows and arrows in their hands, and the arrows were ignited.

"Not good! It's ...... enemy! Seeing this, the Wu Chang reacted immediately, and just as he was about to shout for the news, there was a whoosh, and a flash of fire came and disappeared into his chest.

And the soldiers around him were in the same situation at this time. When they fell, there were more fires on the river, and then, like meteors, these fires flew away from the Yan army camp on the shore of the river.

The weather in June is often heavy rain, but the weather is very hot. It just so happened that it hadn't rained here in the past few days, and the army had always paid attention to dryness, so everything was already very easy to ignite.

When the first rocket hit the tent, a small ball of fire immediately turned into a ball of flame. Then, more flames flashed, and raging flames began to appear in the Yan army's camp.

The fire followed the wind and spread to the surroundings at once. At the same time, the side of the Yan army's camp near Luoshui also began to burn. The two sides came together and burned towards the middle.

The fire spread so fast that almost in the blink of an eye, it connected the middle part of the camp together, and then swept away in the direction of the front camp and the rear camp.

As soon as the fire broke out, the Yan soldiers in the camp were suddenly in a mess. They were nervously awaiting orders, ready to rush to the front of the battle to support. Unexpectedly, he hadn't set off yet, but a fire had already ignited next to him.

The most unfortunate thing is that they all gathered together because of the military order. It just so happened that the gathering place was in the open space between the tents. In this way, when the fire is lit, it is almost like roasting them in the fire.

The panicked soldiers of the Yan Army suddenly became chaotic, running in all directions to flee for their lives, and the entire camp became chaotic as the fire intensified.

Huangfu Zhen was supervising the battle in the front camp, paying close attention to the situation on the battlefield. He also didn't expect that the Tang army would actually avoid the truth and use the two rivers to sneak attack him.

By the time he realized that something was wrong behind him, the flames were already in one piece, and the flames were raging.

"What's the panic? A few of you, immediately rush back to gather your troops and horses, and put out the fire in the camp first. General Ben is sitting here, and he will definitely not let the Tang Army take a step! Also, immediately go find those infiltrated Tang troops, and kill them! Although the emperor was really anxious, in the face of the generals around him, he still pretended to be calm and ordered sharply.

After receiving his order, those generals found their backbone and hurriedly went down to work. Huangfu Zhen was about to sigh, but suddenly found that the Tang army, which was attacking him from the front, suddenly became much more fierce at this time.

"Tang Jun really came prepared!" Huangfu really sighed, and hurriedly sent more people to the front line to stop the Tang army's attack.

When the generals of the Yan army gathered some of the panicked soldiers and began to look around for the Tang soldiers who set the fire, they finally found out how the fire started.

When they found out that the Tang army had dropped rockets on the river, they immediately mobilized a large number of archers and rushed to the banks of Luoshui and Yishui to release arrows on the river.

However, their speed was a little slower, because by the time they released their arrows, the Tang soldiers on the river had already gone down the river.

Then, the Tang soldiers went all the way downstream, all the way to the Yan army camp on the shore to launch rockets, and when they reached the Yan army camp, the entire Yan army camp was completely ignited.

"Our mission is complete, go downstream to join the rest of the brothers!" At this time, the general of the Tang Army who led the troops issued a new military order.

Soon, the little rafts were like ghosts, paddling across the water, and disappeared in an instant.

The fire in the Yan army's camp reflected the entire sky red, and the river on both sides reflected a fiery red color.

At this time, the soldiers of the Yan Army were hurriedly drawing water from the river to extinguish the fire, but in such weather, the fire could not be extinguished at all, but a large number of Yan soldiers were contained.

Due to the fire in the rear, the soldiers of the Yan Army who were fighting fiercely in front of them were suddenly frightened, and no one knew what was going on behind them.

Originally, it was a little powerless in the face of the sharp attack of the Tang army, but at this time, the heart was panicked again, and the army's heart was shaken, and the entire defense line began to waver.

"Brothers, kill with General Ben!" Chen Kangzheng led his soldiers to storm the Yan soldiers near the Luoshui side, and at this time, with their efforts, they finally advanced to the position of the camp gate and opened a gap. Overjoyed, he immediately shouted.

Then he rushed forward, and the soldiers behind him, with enthusiastic cheers, followed him and slashed all the way through this gap.

Once a gap is opened in the defensive line, it means that other places can't hold it. Not to mention that this was the case in ancient times, even in later generations.

Therefore, the line of defense set up by Huangfu Zhen was quickly broken through by the whole line. After Huang Fu Zhen saw this scene, he hurriedly ordered a retreat, and at the same time ordered a part of the soldiers to be transferred from behind to support.

Under the light of this fire, a fierce battle began between the two sides on the land between these two waters.

Huangfu Zhen's camp was very close to Luoyang City, so when the camp caught fire, the people in Luoyang City quickly saw it. Murong Zhong, who got the news, stood on the head of the city and saw the fire in the camp in the south, and couldn't help but feel anxious.

"Hurry up and send someone to find out the situation, what is the situation over there?" Murong Zhong hurriedly sent out spies.

Since the place where the battle is taking place is still more than ten miles away from Luoyang City, it is impossible to see the detailed situation even if you stand on the top of the city.

However, as the fire in the camp became more and more intense, Murong Zhong couldn't wait for the spies' return. He knew very well that if the Huangfu Zhen army was defeated, it would probably be difficult for his side to support it anymore.

At this time, he either went out of the city to rescue, or he watched the defeat of Huangfu, and then he sat in the city and waited for the Tang army to attack the city.

"Send an order to go down, mobilize 3,000 soldiers and horses from the city, and immediately cross the river to help put out the fire! At the same time, send another 2,000 soldiers and horses to immediately detour behind the Tang Army and rescue General Huangfu and them! After struggling for a while, Murong Zhong finally decided to send troops.

"But general, if we send troops at this time, it is very easy to fall into the ambush of the enemy!" A staff member next to him reminded.

"The Tang army is only 10,000 people, and they should all be in the battle with General Huangfu at this time, how to ambush us? Besides, General Huangfu will rest with us, if he is defeated, we will inevitably be defeated, no matter what, we have to save it! Murong Zhong glanced back at the staff member and said helplessly.
