The cold wind began to roar, and the winter that Goguryeo, which was longed for, finally came.

You should know that this cold winter has helped Goguryeo defeat powerful enemies countless times, and they firmly believe that this time will be no exception.

But they did not know the saying in the Central Plains that they had to be strong in themselves.

God can only help you once or twice, but he cannot favor you. After all, everyone lives under the same sky.

"We have not had much time left!"

Dugu Wuyue stood in the valley, looking at the pilot hovering in the air and projecting sky-sky cannons to the ground, and said to Han Yi a little worriedly.

It is early winter now, but it is still relatively dry. But if you drag it back and wait for heavy snow to fall, no one will be afraid of you setting fire.

Han Yi nodded and said, "But it only takes us a few days, so we should still be able to hurry."

"Report——!"

A notice officer ran over and said, "Report to the ambassador, our army has successfully taken down the hilly areas in the south."

Han Yi smiled and nodded, saying, "Now everything is ready, I want to see if the people of Goguryeo are really not afraid of death."

After their analysis, it was difficult for the pilot to come back after projecting a skyscraper. The best flight route was to land in the south, because the glider relied entirely on the flow of air, which was related to the terrain. It had to take down a base in the south for the pilot to land and take off again. However, this was not a difficult task for Su Dingfang. The enemy only defended the key fortress and could not defend the entire south. The Tang army still asked for it outside Pyongyang.

On this day, Han Yi and Su Dingfang and others came to the mountain on the left side of Mayi Mountain. Although they could already feel the biting chill, the sky was still clear, and the sun, which was not too bright, was still doing their best to bring a little warmth to people.

Although it is not easy for Su Dingfang to climb up, no one wants to miss this historic moment.

This is the first time that the Tang army dispatched such a large-scale flight force at one time. In the past, it was dispatched to conduct flight forces for reconnaissance or message transmission, but this is the first time that the flight forces launched an attack on the ground from the air. Although the power is extremely limited, the greatness of any aspect begins from this moment.

Everyone is very looking forward to this.

On the eve of noon.

"Master Yuanbao, you can take off."

Juya came to Yuanjiu's side. He had been helping Yuanjiu train these pilots, and he mainly measured wind speed, airflow, etc. Yuanjiu didn't do this. Yuanjiu just wanted to get the pleasure of flying. There are no instruments these days, so he could only rely on some local methods. Practice makes perfect. Juya is definitely an expert in this field.

Yuanjiu also put away his usual cynicism and a serious expression, because he was most eager to see this scene. In the past few days, he has helped these pilots train day and night, and discussed with Han Yi how to improve the gliding wings to make it easier for the pilot to project the sky cannon.

With the help of auxiliary personnel, ten pilots carried gliders and came to the front of the cliff, and there were lineups behind them.

After Yuanjiu gave the order, ten pilots rushed off the cliff with the help of other personnel, and immediately pulled up after a brief fall.

After a while, the second team rushed down and went down six teams in a row. They maintained a very complete formation in the air and flew over Pyongyang City, because Pyongyang was just inside the mountain nest, and the airflow here was very suitable for flying.

Su Dingfang and the others looked at the pilot who was leaving, their eyes were both excited and nervous.

To put it slightly exaggeratedly, they carry the dreams of generations.

"General, the enemy's big bird is here."

The first person to discover the flying troops was the soldiers on the top of the city, and they immediately reported to Wenshamen.

They had all seen this flight force, because Su Dingfang sent the flight force to reconnaissance from the beginning, but they didn't know what it was, so they called it "the big bird of the enemy."

Wen Shamen looked up at the "big birds", and hated them so much that their bows and arrows could not shoot at these flying troops, so they could only watch them fly over their heads, helpless, but they also knew that the flying troops were here to reconnaise, and the number of reconnaissances was very limited, so he was not very worried. My Pyongyang City was as solid as a rock, and even if you let you know the deployment in the city, it would be difficult for you to capture it.

"General, it seems that the Tang army has never dispatched so many big birds."

A deputy general beside Wen Shamen looked at the neat formation of big birds, passing by, and said blankly.

Wen Shamen frowned slightly and said, "Thank you three hundred people to follow them until they fly back."

"I will obey the order."

At this time, smoke was curling in Pyongyang City. Although the enemy had already arrived at the city, their general told them that the enemy could not attack the city. You can rest assured that the people in this city were relatively calm, but even if they were afraid, they still had to eat this food.

Suddenly, many people felt a shadow passing by their heads and looked up calmly. When the "big bird" came back, they were still very panicked, but they found that this thing was harmless and felt very strange. However, this time there were a lot of people and quite spectacular, and many people went out to watch.

After a while, the first team of pilots came to a very dense residential area and saw them beginning to tilt slightly, preparing to dive.

The team leader suddenly reached out and grabbed a wooden pole on the left, pushed forward, and with a snap, a wooden board was horizontally placed in front of him. This was a specially designed windshield. The glider wings shook slightly, but he quickly controlled it, and the six sky-storming cannons that were originally parallel in front were tilted downward at the same time. The team leader took out a fire from his shoulder and bit it open with his mouth. When he blew it suddenly, a fire flashed inside.

This is a military fire break, and there are also materials such as sulfur added to it. After many experiments, it is ensured that it will not be extinguished. Even if it is extinguished, there are still spares, as many as three.

He put his hand directly on the specially designed handrail in front, lit the leads hidden on both sides of the thin bamboo tube, and saw the flames rising inside, and the frequency of flashing was getting faster and faster.

After a moment, I heard a whizzing sound.

Six flames were sprayed on the fireproof board behind the sky-storm cannon one after another. This was very dangerous. You could not burn it. Even if you burn a hole, you would have a special fire guard behind it, but it was not copper or iron, but wood, because the copper and iron were too heavy.

In addition, there is a push rod on the right. This push rod is used to give up the sky-rushing cannon device. As long as you push it forward, the entire sky-rushing cannon device in front will fall down, because the stability of this sky-rushing cannon is just like that. If it is not shot out, it will burn directly in the glider. The pilot will definitely finish playing it, and Han Yi made this device. This device is very clever, but it is very simple to do. Anyway, as long as one of them is not shot out, the pilot must immediately give up the entire device.

Fortunately, all six sky-storm cannons were shot very safely.

The Goguryeo people on the ground were all confused. Why did the "big bird" still spit out today?

Although this is just a sky-rushing cannon, if it is put into the future, no one may have looked at it. It can't even compare to a one-dollar firework. However, in this era without gunpowder, few people have seen it before. The sky-rushing cannon is fast, and it sprays flames, and makes the sound of breaking through the air, as if it is the sound of a big bird.

The Goguryeo soldiers who had been following him were all stunned. They had no solution at all, and they didn't even know what this thing was.

But they soon understood that when the sky-rushing cannon was about to land on the ground, a ball of fire suddenly ignited in the air.

"ah!"

A scream sounded on the ground.

At the same time, the pilots behind also projected sky-rushing cannons on residential areas. A total of 60 pilots and 360 sky-rushing cannons poured down. Although these 300 sky-rushing cannons were not enough for the huge Pyongyang City, they were all concentrated in one area to project, and there was a rain of fire above them, which was very spectacular.

Some fireballs will be extinguished when they fall on the ground, and they will be useless. However, once they fall on those thatched huts, it is really fatal, because they are oil inside, which can be burned for a long time, and they are stuck. What's so bad is that most of the houses that the people live here are huts, and more than 30 houses were lit up in an instant.

It was not until the smoke came out that the people in the city realized that it was a damn thing that these big birds were not here to investigate, but to set fire.

Suddenly, the city was in chaos, and the people covered their heads and ran around. In fact, the fire was not very big, but they were all scared because they could only see some of them. At the same time, Wen Shamen also arrived in person. Seeing the fire in front of him, there was a look of fear in his eyes, but he still suppressed the fear and immediately organized everyone to put out the fire. Although the fire was not big at the moment, if you want to keep it burning like this, this residential area might have to be burned.

But on Mayi Mountain there was a lot of laughter.

"Success!"

"Success!"

Su Dingfang looked at the thick smoke rolling over Pyongyang City from a distance. Of course, he knew that it had succeeded and immediately burst into laughter.

The pilots behind were also very excited. This is their honor!

"In the afternoon, I will lead the team in person, haha!"

Yuanjiu said excitedly with shaking body.

Han Yi rolled his eyes and said, "Master Yuan Castle, don't join in the fun."

Yuanjiu said seriously: "They can do it, can't I? They are all trained by me, and none of them can beat me in their flight skills."

Han Yi looked directly at Yuan Liehu. He is his father, so of course this matter is left to you.

Yuan Liehu walked over and whispered: "Dad, this is still dangerous!"

"There's a big danger." Yuan Jiuyi said righteously: "You kid don't know anything. Of course you think it's dangerous. It's safer than sailing on the sea. Go and go, I've decided. I'll lead the team in person this afternoon. If you want to stop me, I'll take off at another mountain."

This is his dream. How could he sit still when he sees the flying team members so majestic?

Yuan Liehu also knew Yuan Ji's personality. When he saw that Yuan Ji's eyes were starting to ejaculate, he knew that he would definitely not be able to stop him. Yuan Ji came here through mountains and rivers just for this moment! He shook his head helplessly at Han Yi.

Han Yi sighed softly. In fact, Yuan Ji was right, but the glider was much safer to sail on the sea today.

At this time, Ono suddenly walked to Han Yi and whispered: "Brother Han, I want to try it too."

Han Yi was almost crying when he heard this and said, "Brother Ono, don't go."

Ono said: "Brother Han, don't worry, it's such a short distance and the surrounding mountains. No matter how good I don't help, I can land in the mountains. They can't catch me in the mountains."

Han Yi saw that Ono's big eyes were full of desire. He was not someone who liked to interfere with others, so he nodded and said, "Then you have to be careful."

Ono nodded in joy.

Yuanjiu walked over excitedly and said, "Ono, let's not throw away the small cloth strips, bring some weapons to try it."

Ono nodded excitedly and said, "Even if you bring your weapons, you can bring some small cloth strips."

For both of them, there was no more pleasure to fly over, and there was no view of Pyongyang City. They mainly wanted to try the pleasure of attacking the ground from the air.

By the afternoon, when the smoke over Pyongyang City gradually faded, the two hundred pilots were all on standby and divided into two columns, led by Yuanjiu and Ono.

Everyone was very excited, and they were not afraid at all. People who knew how to fly would not be afraid. Just like people who knew how to swim in the water, only those who didn't know would be worried about it, but this was so handsome that no one could resist this charm. The only regret was that there was only Yuanjiu among them, and Ono carried it for the sky-storm cannon, and the rest were small cloth strips.
Chapter completed!
