The drone soars at an altitude of 200 meters, and on the color LCD screen of the controller, various scenery of fields, woods, streams, and villages alternately skim, and the entire northern land is in full view of the vast winter sky. Xu Ying snuggled up to Yang Ming, looking at the pictures on the display screen in surprise, and had a feeling of fascination, so much so that Yang Ming's gentle kiss on her face didn't react in time.

"General, what's going on?" Xu Ying asked in a muttered voice.

"It's the video footage from the plane in the sky...... Yang Ming gently rubbed Xu Ying's face, "It's a pity that there is no GPS signal, so I can only fly along the official road, otherwise I will fly over from the top of the mountain, and the scenery will be better." ”

RQ-11B has a GPS positioning function, if there is a GPS signal, then you only need to enter a location coordinates, and the drone will fly over by itself, but obviously now Yang Ming can only watch the video screen and control it manually, and fly to Beijing City with the official road as navigation.

"If I'm not mistaken, today should be the day when Huang Taiji attacked Beijing City and left a letter at Guangqumen."

"Am I not mistaken?" Xu Ying asked strangely, "What does the general mean?" ”

"I can't tell for a while......" Yang Ming kissed Xu Ying's face lightly again, sniffing the sweet fragrance of skin and fat powder, "I will tell you ...... later"

"General, is this the city of Beijing?" Xu Ying pointed to the screen and shouted.

The tall and wide walls appear on the screen, and you can faintly see the golden yellow spots in the center of the city, which are the glazed tiles of the Forbidden City glittering in the sun.

"Well, we're flying along the walls now." Yang Ming gently pressed the control knob to make the drone deflect slightly to the left and fly south in the sky on the east side of Beijing's city walls.

"Dongzhimen!" Xu Ying screamed again.

"Well, if you go further south, will you go to Guangqumen?" Yang Ming rubbed Xu Ying's face and responded softly.

"General, further ahead are Chaoyang Gate and Dongbian Gate, the city wall of Dongbian Gate has a section protruding, and after Dongbian Gate is Guangqu Gate." Xu Ying said affirmatively.

"How far?"

"Ten miles!" Xu Ying stared at the screen, "Ten miles from Dongzhimen to Guangqumen." ”

"It's there in five minutes." Yang Ming was a little surprised that Xu Ying knew about Beijing City, "When you tell me." ”

"It's already at Dongbianmen!" Xu Ying pointed to the screen and said to Yang Ming.

"Hmm."

From Dongbianmen is the outer city of Beijing. The width of the outer city in the east-west direction is more than a thousand meters wider than that of the inner city, and Yang Ming controls the drone to offset some distance to the east and continues to fly south along the city wall.

"Guangqumen!" Xu Ying grabbed Yang Ming's shoulder and arm, "Oh my God......"

There is no need for Xu Ying's reminder, a dense array of Houjin Army appeared on the screen of the drone, before the array, nearly ten artillery pieces were fired at the city wall of Guangqumen, and the smoke from the muzzle of the cannon rushed up to the sky, gradually dispersed, and the thin smoke seemed to be ethereal in front of the camera. You can even see the defenders running on the walls, a cluster of cannonballs bombarding the arrow stacks, and broken masonry flying everywhere.

"Don't be afraid, you can hold it for me." Yang Ming handed the controller to Xu Ying, "It's them who should be scared." ”

Yang Ming quickly typed a rough latitude and longitude data into the Afaz interface of his military notebook, and the satellite map swiped to move to the modern city with many high-rise buildings. With a few random mouse drags, a wide avenue moves to the center of the interface.

The west side of the street is Guangqumen Inner Street, the east side is Guangqumen Outer Street, and the overpass at the dividing point is the Guangqumen Gate of the year.

At a position of 1,200 meters to the east of Guangqu Gate, Yang Ming clicked the mouse fiercely.

The Afaz system instantly gives striking best ballistic data and firing data.

Yang Ming pushed the M795 grenade into the gun chamber, turned the steering machine and the high and low machine, accurately adjusted the secret position to the data given by Afaz, and then pulled the gun rope. The barrel of the cannon slammed back, and the earth trembled with a loud rumbling sound, and the branches of the locust trees around the cannon shook to the ground.

20 kilometers, the ballistic time is 57 seconds, enough to receive a kiss, Yang Ming hugged Xu Ying into his arms.

Outside the Guangqu Gate in Beijing, Huang Taiji, who was watching the battle immediately, watched the artillery of the Houjin Army firing quietly, and the tall, strong, and unbreakable Beijing City revealed its fragility under the bombardment of the artillery. Huang Taiji was more convinced and attached importance to the power of the cannon, and at this moment, he had decided to invest the power of Houjin to build a powerful artillery unit.

Historically, after Huang Taiji captured Zunhua, he got the largest steel plant in the northern region of the Ming Dynasty; After the capture of Yongping, a group of Ming Dynasty artillery craftsmen were captured. These craftsmen, under the leadership of Jin Zhiyang after the surrender, made forty Hongyi cannons a year later. Huang Taiji excitedly engraved the name of "Tianyou Cheering General" on the cannon body, and noted the names of the supervising officer and the chief military officer, the supervising officer Ding Qiming, the preparation of the imperial Zhu Shilong, the casting general Wang Tianxiang and Dou Shou, and the blacksmith Liu Jiping.

These cannons eventually helped Houjin seize the world.

Huang Taiji took out the paper tube containing the letter from his bosom and played silently with it in his hand, he had an urge to tear the letter inside the paper tube to shreds, and then scatter the fragments into the sky.

In the sky, a bird that does not belong to this era is slowly soaring and circling, the CCD lens looks down on the earth, and the sound of the humming motor reaches the ground, which is already below the hearing limit of the human ear.

Suddenly, Huang Taiji heard a strange sharp sound, which seemed to be the sound of Yu Ling breaking through the air. In less than a breath, the sharp sound became louder and faster, and it seemed to change from one feather feather to ten thousand feather feathers shooting in his direction from all directions.

Huang Taiji frowned and looked up for the sound, only to find that almost everyone around him turned their eyes to the sky, as if they were looking for the source of that sound.

Suddenly there was an overwhelming cloud of smoke and dust in front of him, followed by a deafening boom, the earth shook violently, and the horse sitting down neighed in fright, raised its front hooves, and almost lifted Huang Taiji off the horse.

The grenade, which had been in the air for 57 seconds, reached the end of its trajectory.

A strong shock wave mixed with dirt rushed towards the face, and the horse twisted its hooves to the side and back, almost unable to support the rider on horseback. Huang Taiji held the reins hard, twisted his body to maintain his balance so that he would not fall off the horse's back, and finally, after withdrawing more than a dozen steps, the war horse stabilized.

The surrounding Baya cavalry was in chaos, several cavalry fell under their horses, and the frightened war horses rode into the distance with the big umbrella of the Yellow Dragon that fell to the ground.

"Rayfa! —" Haug, who was swaying on horseback to maintain his balance, shouted, and there seemed to be a hint of joy in his hysterical voice. Finally, for the battle under the city of Shunyi, he no longer needed Xianglin's sister-in-law's defense.

As the smoke cleared, a fan-shaped crater six feet deep and several feet in diameter appeared on the ground in front of the side, which was due to the shape of the ballistic trajectory and the direction of the fan's spread.

Around the crater, the corpses and stumps of the Houjin army and war horses were scattered horizontally, and some of the "corpses" were obviously not completely dead, writhing and spasming on the ground. Farther away, the soldiers who had fallen from their horses struggled to get up, but they lost their balance in circles and fell to the ground.

"Father Khan, go!" Haoge struggled to hold the reins and moved his horse closer to Huang Taiji's side, "That barbarian's Leifa is here again......"

Huang Taiji's eyes flashed brightly, he looked around, and suddenly his legs were clamped, and he rode his horse towards the city wall of Guangqumen.

"Father Khan—" Haug shouted, and chased after him with his horse, and the Baya cavalry behind him hurried to catch up.

The defenders on the city wall also seemed to be stunned by the huge thunder, and watched in amazement as Huang Taiji's group of men and horses rushed towards the city wall, and only when they were almost close to the city moat did they condescendingly shoot a wave of arrows.

Huang Taiji rode a horse while running, while holding a bow and arrows, and with the momentum of the horse, he shot the feathered arrows with the letterhead into the city. When the arrow was fired, the reins were tightened, and the horse stopped with its front hooves, and several feathered arrows from the city wall fell to the ground in front of the horse's hooves, and the feathers on the shaft of the arrows trembled slightly.

The cavalry of Hauge and Baya in the back caught up, and they turned their horses' heads with Huang Taiji and ran eastward.

Yang Ming looked at the display screen in his hand, the smoke and dust dispersed, and the crater was exposed, and then he used the mouse to click on the geometric center point of the crater on the Afaz interface, and the system immediately gave the ballistic deviation correction data. Yang Ming used an instantaneous explosion fuse, that is, the moment the warhead touched the ground to trigger the explosion, in order to obtain the location of the shell's landing point to correct the trajectory deviation. Ballistic deviations can be caused by inaccurate positioning, wind direction, or errors in the amount of the propellant, which will be corrected for the next shot.

The second shell is pushed into the breech, this time using an air-blast fuse, and the corrected trajectory will exert the maximum power of the air-blasted high-explosive grenade, accurately killing and injuring a large number of enemy personnel.

"Xu Ying, you come and pull." Yang Ming adjusted the secret position of the howitzer according to the correction data given by the Afaz system, and shouted Xu Ying.

Xu Ying was stunned to see the bloody picture on the display screen, and when she heard Yang Ming calling herself, she carefully held the feeder on the controller and hurried over.

"Pull the rope tightly with both hands, center on your left foot, rotate your whole body to the left, and pull hard." Yang Ming took the controller from Xu Ying's hand and handed the cannon rope to her.

"Do you have to use a lot of force?" Xu Ying asked.

"No, that's pretty much it."

Xu Ying's delicate body twisted, the rope moved the fire, and the earth roared.

"57 seconds ballistic time." Yang Ming pointed to the English "57 Seconds" on the Afaz interface and said to Xu Ying.

"General, let the slave family take a closer look this time......" Xu Ying meant to ask Yang Ming not to hug her and kiss again this time, she wanted to see the picture when the cannonball landed.

"Hehe, okay." Yang Ming pulled the bolt, cleaned the chamber, and pushed in the third grenade.

It's a shrapnel!

"Father Khan's dragon body is the most important ......" Hao Ge, who chased to Huang Taiji's side, tried to overcome his fear, "This barbarian's thunder law is powerful, please ask Father Khan to order the whole army to retreat first......"

The sharp voice broke through the air again, and the face of Hauge, who had not yet finished speaking, suddenly turned pale, and the surrounding Baya cavalry also raised their heads and looked around, and there was a commotion among the men and horses, as if the land under the horse's hooves was an endless scorching frying pan, and the people on the frying pan wanted to escape, but they didn't know where to flee.

"Idiot!" Huang Taiji roared at Haoge, "This is a cannon!" ”

A deafening rumble was heard, but this time the ground did not tremble, or rather, it did not tremble as violently as the previous shell. The grenade exploded at a height of 15 meters above Mang Gurtai's Blue Flag Array, and the entire Blue Flag Array was shrouded in gray-pink smoke, which was mixed with blood mist.

The severed limbs flew out of the smoke and dust mixed with the blood mist, and fell to the ground, spinning and jumping, turning the land into an asura field.

"The whole army retreats!" Before the smoke and dust that shrouded the Houjin army cleared, Huang Taiji gave the order.

Later, the Jin army began to retreat, and thousands of men and horses rushed towards the desolate fields in the east, not even bothering to collect the bombarded cannons that had bombarded the walls of Beijing.

A third shrapnel flew over with a rapid screech. This kind of artillery shell is a special personnel personnel bomb, and 12,000 small steel arrows weighing 3 grams in the body of the projectile explode directionally over the target, forming a rain of arrows falling from the sky within 15,000 square meters on the ground.

The Houjin army has retreated, the formation is no longer strict and dense, the use of shrapnel is the best choice, the dense rain of arrows after the explosion of the shrapnel makes almost none of the Houjin soldiers in the target range survive.

Yang Ming controlled the drone and continued to track the direction of the retreat of the Houjin army, and the screen was a mixture of people and horses, and the Houjin army scattered on the wide ground scrambled to retreat to the east. The RQ-11B's maximum speed of 90 kilometers per hour is completely no problem to keep up with the retreat of the Houjin army, but it is far away from the city of Beijing, there is no positioning reference, there is no GPS signal, and it is impossible to obtain the enemy's position coordinates, and he can no longer open fire.

Let's call it a day, Yang Ming operated the drone to return. Today's mission is over, and the three artillery shots are gone, and he estimates that the casualties of the Houjin soldiers should be more than 1,500.
