Shi Yan's whole body suddenly tensed, and a chill skewed from his head to the soles of his feet.

Standing at the head of the city, he quickly turned his head to look in the direction of the north wall, and in the dark night, he suddenly saw a little red light in that place breaking through the sky, silently. This red light standing here doesn't seem big, but Shi Yan, as a leading general, has rich experience in battle formations, although it is at night, he can still immediately visually detect the distance of the red light and the location.

This red light, at least fifteen hundred paces away, was almost at the canyon passage outside the gully under the north wall. And if you look at the location of the red light, it should be still on the north city wall. And at least three feet higher than the north wall!

The vicinity of Blackstone Ridge was empty and silent, and the red light in the dark night sky became more and more conspicuous!

"This, how is it possible!"

After Shi Yan quickly calculated it in his heart, he was also frightened by the results he had calculated. At first, he thought it might be some kind of signal flare from the Qin army, or something like a Kong Ming lantern. But just calculated, that thing appeared outside the north wall, and it had risen all the way above the north wall by at least three feet, and it seemed to be rising. Looking at the size of the red light, it was not a Kong Ming lantern at all, nor was it a signal flare.

Because, what made Shi Yandu stunned for a while was that in the northern sky, at this time, a little red light continued to fly up, and in a short period of time, the sky above the north wall was already covered with at least thirty points of red light.

Dozens of huge clusters of light shone in the night, as if dozens of huge monsters had suddenly emerged from the darkness, and the terrifying glowing eyes flickered before the monsters devoured them.

The Shatuo defenders on the city walls were almost stunned. Many people have no idea what it is. Many people even dropped their weapons directly. Kneel at the head of the city, and bow down in prayer.

"What's that?" Shi Yan's lieutenant Shi Jianxiong opened his mouth wide, his eyes full of confusion.

Shi Yan also looked up for a long time, and only after a long time did he mutter: "It's Kong Ming Lantern!" ”

According to legend, the Kong Ming lantern is a kind of lamp invented by Zhuge Kong Ming during the Three Kingdoms, which can fly higher and higher directly with a candle flame and float to the distance by the wind, and has been used to transmit military signals on the battlefield. Up to now, Kong Ming lanterns have even become an ordinary thing. On the night of the New Year's Festival, many places have the custom of putting Kong Ming lanterns at night. The fire tree and silver flowers never sleep, and the lights bloom thousands of flowers at night.

But although Kong Ming lanterns can rise into the sky, they can only be extremely small and light. Often, the largest is the size of an ordinary lantern, but what they see in front of them, someone can already see the approximate shape.

They were very large, each at least a few feet in size, and there was a raging fire burning with them, and some people had seen them. Above the large fireball suspended in the air, there were shadowy figures walking.

The Qin army used firearms without permission. The Qin army has the most advantageous application of firearms in the world, but no matter how powerful they are at researching firearms, they have never heard of them researching such a huge Kong Ming lantern?

God, what a terrifying monster this is to be able to carry a team of people and horses to fly more than ten zhang high in the air.

An ordinary Kong Ming lantern can carry a letter, and it stands to reason that since it can fly into the sky with a letter, then if you do it in Dali and make a huge Kong Ming lantern, you can also lift off with more weight. But in fact, there are many people who have planned to do this, but they have never actually realized it.

The huge Kong Ming lantern that can carry people is just a fantasy!

Shi Yan didn't know how the Qin army of the Dao Dao made these huge Kong Ming lanterns that were several zhang high, but now in the sky above the gateless city wall to the north, the Qin army had already flown directly above the heads of the defenders on the huge Kong Ming lanterns.

No matter how the Qin army managed to do this, the key now was how they would deal with this move of the Qin army.

The Qin army's raid method was completely unfolded according to the conventional offensive and defensive methods of the Black Stone Ridge. This surprise attack of the Qin army directly caused almost half of their important defense lines such as the gateless north wall, the deep stream in front of the fort, the fortified fortress city, the tall fort wall, and the arrow tower to lose their effectiveness.

No one expected that the Qin army would actually use a large Kong Ming lantern to launch a surprise attack in the northern city, which caught the defenders of the Black Stone Fort, who had been gathering heavy troops at the south gate of the main gate and the second auxiliary gate of the east and west, by surprise for a while. What's even worse is that no matter how high the city wall is, in the face of the Qin army falling from the sky, it has lost its due role.

The towers, the battlements, which were supposed to play an important role, were now useless, and the defenders of the northern city only hated that they had not been able to add a layer of masonry to the top of the walls to prevent arrows and bombs from pouring down from their heads!

Shi Yan's eyebrows were already tightly wrinkled together, things were not good!

The Qin army really came to the Black Stone Ridge, and it came in the form of divine soldiers descending from the sky.

Shi Yan now has no idea how many men and horses the Qin army is attacking from the road, nor does he know how many of their big Kong Ming lanterns there are, nor does he know how much gunpowder they have, the only thing he knows now is that if he can't immediately mobilize a group of elite troops to stabilize the north wall, then the famous dangerous fortress known as a man and a man can't be opened, it is possible that the north wall will fall immediately.

Above the north city wall, the huge Kongming lanterns like small hills were slowly rising from the north not far away, and then moved over.

These Kong Ming lanterns are more than ten zhang away from the top of the city wall, and the angle is up, the bows and arrows of the defenders on the city wall are difficult to shoot at all, even if they operate a ballista to throw cannons, the angle is not enough. On the contrary, all the Shatuo guards who stayed at the head of the city were like mirrors, once these damn Kong Ming lanterns adjusted their positions, the next thing would definitely be the artillery bombardment that the Qin army had always been the best at, and the arrow rain would cover it.

The height is unbearable, but Li Qiusheng, the squadron leader of the Dapeng Bird Squadron, is holding the rope on the hanging basket at this time, covering his body with leather armor, wearing thick cotton clothes, wearing leather gloves on his hands, and wearing leather hats and masks on his head, blowing the unobstructed cold wind in all directions, but he still can't stop the blood boiling in his heart!

Although the Dapeng Bird Squadron has been established for a long time, and the officers and men of their special hot air balloon unit have also experienced hundreds of aerial take-off flights, every time they take off, standing in the hanging basket, feeling the strong wind blowing on all sides, and the ground city characters that have become small in their eyes, make his blood boil again and again.

This was the first real combat of the Roc Bird Squadron, and it was again on a winter night. This is not a good time to fight. But the military order is like a mountain. Li Qiusheng will not refuse. Even if he doesn't give the order, he will go to war.

As the first batch of air units of the Qin Army, these elites selected from the special operations brigade have long been hungry and thirsty, waiting for the first air battle for a long time!

The hot air balloon of the Golden-winged Dapeng Bird is Li Qiusheng's landline, in addition to the squadron leader Li Qiusheng, this hot air balloon also carries nine people, which is a standard squad of ten people. The hot air balloon is made of silk and special lacquer. The bottom is a lacquered rattan basket, and the fuel burned is black oil crude oil, which is suitable for combustion.

There were ten people in the hot air balloon, each equipped with a bow and arrow, leather armor, and bomb oil!

The herald behind him relied on a few lanterns to move in the air with other hot air balloons, and soon, the herald reported loudly.

"Golden Roc No. 1 is ready!"

"Black Roc One is ready!"

"The cyan Dapeng No. 1 is ready!"

"A total of thirty-one hot air balloons of the Dapeng Bird Squadron have all been lifted into the air and are ready to go, please give the squadron leader a combat order!" The observer reported loudly, and his tone was full of excitement. This battle will change the battle pattern for thousands of years. They will all go down in history!

"Send the signal and plan according to the predetermined combat plan. Attack now, drop bombs, and bomb the northern walls! ”

Shi Yan led the headquarters guards to take the lead in rushing to the north wall, although the north wall did not have a city gate, but if the enemy attacked from the sky, the defensive effect of the city wall would be greatly weakened. The north wall has always been guarded because there is no city gate and the city wall is tall and strong. At the moment, it has become a weak link.

Before he could reach the north city wall, there was a sudden bright light in front of him, and the dark night suddenly brightened as day!

There was a loud explosion in my ears!

Suddenly a large fire broke out on the northern wall, and the night was so dark that it was impossible to see anything clearly. But with this firelight, the old history had already seen dozens of huge fire-breathing monsters in the sky constantly spitting out a series of black spots from that big belly.

Some of the black dots fell on both sides of the city wall, but some of them still fell on the city wall, and the explosion and fire were connected, and suddenly several tall arrow towers and corners were wiped out, and many defenders were directly blown to pieces, and the bones were gone!

The Qin army's sharpest firearms and covering attacks!

In this world, only Qin Jun has such a sharp gunpowder strength and such a strong net worth, and dares to throw precious gunpowder as if he doesn't need money.

Shi Yan groaned in his heart, this style of play can be described as Qin Jun's signature style of play. It's just that in the past, the Shatuo army fought against the enemy, except for the Qin army, it had not encountered the same rich enemy, so this kind of firearm array fought very little. But he didn't expect that Sha Tuo and the Qin army would fight so quickly, and in this extremely dangerous Black Stone Fort, the Qin army was repeatedly surprised.

The Black Stone Fort was indeed dangerous, but the Shatuo people didn't expect the Qin army to come from the sky, and they didn't expect them to have such a fierce firearms attack!

With mental calculation or unintentional, Shi Yan suffered a big loss!

I was careless, I didn't expect the Qin army to dare to attack Blackstone Fort, it was still such a surprise attack!

In just a moment, he had roughly guessed Qin Jun's plan. Using Kong Ming lanterns to raid in the air not only has the effect of raiding, but also can deter the Shatuo army, and the choice of the north wall to raid is the point of Shatuo's defense.

The choice of the north wall as the breakthrough point was indeed unexpected, but it was also the most promising breakthrough point. Once the Qin army was allowed to raid and occupy the northern city wall and occupy this northern supreme point, the Qin army would continue to enter the Black Stone Fort. And losing the danger of the city and the defense of the city, Blackstone Fort is just an ordinary small city, with only 3,000 defenders, and it can no longer stop the Qin army's attack.

"Quick, hold the north city wall, and never take half a step back!" Shi Yan watched that sometimes the corner tower of the arrow tower was hit and collapsed, and he couldn't help but feel anxious, Beicheng must not be lost!

On the slope of the hill opposite the Black Rock Ridge, Li Wei and the generals were quietly watching the first aerial battle in the history of thousands of years of war, and they were all shocked by the continuous shining and rising fire!

There are only 31 hot air balloons in the Dapeng Bird Squadron, but just these 300 people, at this time, they bombarded the north wall that was as impenetrable as an iron wall, and the arrow towers, corner towers, and Shatuo defenders screamed and groaned under their feet, but they were powerless to fight back!

A smile finally appeared on Levi's crumbling face.

He turned his head and shouted at the herald behind him, "Tell the Black Bat Squadron that the Roc Bird has successfully completed the scheduled mission, and they have successfully attracted the attention and strength of the defenders of the Black Stone Fort to the northern city wall. Now, it's time for them to strike! ”

"The Black Bat Squadron is ready!"

"Attack!" (To be continued......)
