It was night, and the sky was overcast, so dark that you couldn't see your fingers.

On a steep slope adjacent to the valley, Qin Feng, who was wrapped in a thick black robe, was standing side by side with Ling Yuanqing, observing the scene in the valley. There are more than a dozen black-clothed men around Gongwei, all of whom belong to Zhao Yuanjin's henchmen.

Thousands of elite black-clad soldiers waited quietly at the foot of the hillside in the distance. There was also a group of imperial soldiers on night duty lying on the side, and now they had all turned into corpses.

The images in the night vision binoculars are certainly not as clear as those in the daytime, but the general layout of the valley can be seen, with conical columnar granaries lined up in patches, and the occasional yawning and sleepy soldier can be seen.

This place is far away from the battlefield, and it has always been safe and sound, so the vigilance of the imperial court soldiers on duty is not high, and they never thought that Zhao Yuanjin's soldiers would find this place.

"Looks like there aren't a lot of defenders, sir, shall we?"

Ling Yuanqing said in a low voice. A thousand elite soldiers touched here at night, and encountered many enemy sentries along the way, although they were all solved in time, but after a long time, it was still possible to be detected by the imperial army, so it could not be delayed.

Qin Feng nodded, turned around and walked to a place where the soldiers could not see, and with a wave of his hand, the light and shadow flickered, and one after another small trebuchets appeared around, as well as a large pile of clay pots filled with oil.

When he took out all the things in the dimensional space, the dead soldiers came and escorted him to the side.

In fact, even these dead soldiers didn't know what the identity of Qin Feng in the black robe was, and before leaving, they only received a strict order from Zhao Yuanjin personally, even if all the dead light was complete, they had to protect this gentleman.

Ling Yuanqing let out a low snort and called the soldiers below.

After seeing the trebuchet and the clay pot, the soldiers gathered around were all shocked, and did not understand how these things came out of nowhere. Of course, in Ling Yuanqing's stern order, no one dared to ask.

Thousands of soldiers started at the same time, using trebuchets to launch these clay pots all over the valley, and some soldiers directly picked up the clay pots and threw them down the hillside in front of them. By the time they hit the ground, they were mostly shattered, and viscous oil was splattered everywhere.

"What is this? Bastard! There is an enemy attack! Fast...... Get up for me......"

It didn't take long for the sound of the crashing and the cracking of the pottery to finally attract the attention of the soldiers who stayed behind in the imperial court, and soon the sound of the gong to warn was "clanging".

However, it was too late, and as dozens of flaming rockets fell, igniting the oil one after another, flames burst into flames all over the valley. And the fire was quite powerful, and soon many granaries were lit, and it became a large torch burning in the dark night.

"End...... It's over......"

The commander of the granary was so frightened that his hands and feet were cold, and his cold sweat soaked his heavy clothes, and once the granary was burned down by the enemy, what kind of terrible consequences would mean for the whole army, his mind could naturally think of it.

When the time comes, not only will the army's morale collapse, but the angry general will definitely cut off his head to vent his anger, and no one will be able to teach himself.

"Quick...... What are you still doing? Quickly put out the fire——! ”

He roared like madness, his voice trembling with a palpable tremor of fear: "The grain must be snatched out, must be snatched out!" Otherwise none of us will survive! ”

The soldiers in the barracks poured out like crazy, and most of them were disheveled, picking up all kinds of equipment and rushing to put out the fire.

In the open area of the camp, there are many large vats, all filled with water, which is standard in the grain and grass storage area, and it is a precautionary measure in case of a fire.

It's just that this kind of preparation is effective for ordinary fires, but it is not enough to meet fires caused by a large amount of fuel.

In front of the burning granary, buckets of water were poured on it, and the fire not only showed no signs of weakening, but had a tendency to spread.

"Damn! It's oil fire, with sand and soil...... Fast...... Fast! Several officers shouted and cursed.

In this era, there were no foam fire extinguishers, dry powder fire extinguishers and other sharp weapons, so this kind of fire can only be solved with sand and soaked quilts. However, due to the large area of the fire, it will be difficult to control it for a while and a half, especially when clay pots and rockets continue to fall from the sky, and the fire has not decreased at all.

"Bastard! Go and kill all the traitors who sneaked up on me right now! The commander roared hoarsely.

Hundreds of soldiers threw down their fire-fighting tools and rushed to the hillside in the distance.

"Shoot the arrows!"

Ling Yuanqing ordered with a sneer.

The area under the hillside was already covered with oil, and a row of rockets went down, instantly raising a large area of firelight, drowning all the imperial court soldiers who rushed over, and the sound of anger and scolding was endless, mixed with heart-rending screams.

"General, we have too few manpower, hurry up and ask the battalion for help, right?" A battalion with a blackened face rushed over and spoke urgently.

Since it was a safe area in the rear of the large camp, there were not many soldiers guarding the grain and grass, only two or three thousand, and they were unable to deal with such a catastrophic emergency.

The commander of the capital made his face change slightly, and he should ask for help, but after all, it is more than ten miles away from the camp, and when the reinforcements arrive, how much grain and grass will be left in the valley?

At that time, the generals who came to help him might take down the sacrificial sword on the spot!

"Okay, you take a few people to the camp at once." The commander reluctantly said.

The battalion did not suspect him, and hurriedly called a few of his own soldiers to leave in a hurry.

When the other party was far away, the commander silently rushed into his barracks, hastily cleaned up, changed into the clothes of ordinary soldiers, and slipped away in a smoke of chaos.

The main general was nowhere to be seen, and the officers and soldiers below had no backbone, and the situation became more and more chaotic.

"Almost, retreat!"

Ling Yuanqing saw that the fires in the valley were everywhere, and most of the granaries had turned into blazing torches, reflecting the surroundings as bright as day, and said with satisfaction.

In the camp of the imperial army.

There was a furious roar from the back tent, and Feng Qingyun kicked the two snow-white carcasses on the bed off the bed with a fierce kick, grabbed his saber and rushed out of it naked.

“…… The thieves attacked the granary?! What's going on here? Say it! ”

His eyes were blood-red, and he glared viciously at the battalion who had come to report the news.

"Big ...... General, it's true, just an hour ago, thousands of thieves with a large amount of fire oil sneaked up on the granary, our numbers were too small to resist, and the general was asked to send reinforcements quickly. The battalion was trembling and trembling.

"Bastard! It's all a bunch of useless stuff! ”

Feng Qingyun raised his sword and fell, and the head of the big man flew up in the air, and blood was splashed all over his body.

The surrounding group of guards was silent, and no one dared to make a sound.

"Now...... It's all over ......."

Feng Qingyun, who had calmed down from the shock, only felt like falling into an ice cellar, and muttered to himself with a dejected face.

The siege battle a few days ago had already made the morale of the army extremely low, and now the grain and grass were burned by the thief army, how can the next battle be fought?
