In order to let Zhang Yong and Tian Peng operate the machine gun with peace of mind, Yang Yifei took out two safety ropes and tied them around their waists, and hung the other end on the hook in the helicopter, so that they would not have to worry about falling down.

The Black Hawk's hatch machine gun is the Minnigan m134 rapid-fire machine gun, which is the mini Vulcan, with a caliber of 7.62x51 mm.

Its rate of fire is adjustable, and the rotation speed is controlled by adjusting the motor current to achieve the purpose of adjusting different rate of fire. The minimum is 300 rounds per minute and the maximum is 6,000 rounds per minute.

Yang Yifei adjusted it to 600 rounds per minute, and could fire 10 rounds per second, which was not slow. If the fastest rate of fire is used and the bullets are exhausted in a few strokes, it would be a waste of ammunition.

A weapon like a rapid-fire machine gun is not only flat on the ground, but it is very cost-effective to use the maximum rate of fire. It is very cost-effective to shoot from the sky because it cannot form the effect of a "fire whip".

The brackets of the two machine guns were pushed forward, causing the barrel to run out of the cabin door. In this way, the cabin door could no longer be closed and could only fly in the cabin.

Zhang Yong and Tian Peng sat behind the machine gun, with safety rope tied to them, Yang Yifei also put two boxes of bullets beside them, and Liu Yuxuan was responsible for the bullets.

After preparing everything, Yang Yifei and Li Mochou got on the cab, activated the system, and flew into the sky and headed east under the eyes of the disciples of the Quanzhen Sect.

It was also the first time I took a plane. Although Quan Zhen Liuzi was a little nervous, he was not worried about Zhang Yong and the others, but more excited.

Because they firmly believe that Yang Yifei is a god among the gods, and their understanding of the existence of gods is much deeper than that of Zhang Yong and others, so naturally there is nothing to be afraid of.

Xiaolongnu is purely ignorant and fearless, and has no idea of ​​being afraid. In her simple thinking, since her senior sister and brother-in-law are there, it is definitely safe.

Yang Yifei drove very smoothly, and rarely had a large inclination in the fuselage. Even if the turn was turned, it would turn slowly. Although the curve of the turn was much larger, it could ensure smoothness.

So Quanzhen Liuzi quickly relaxed and began to appreciate the high altitude scenery, looking forward to the realm of immortals.

...

In the early morning, it was the time when the battle of the new day began. The Mongolian Army Camp, five miles away from Tongguan, was just over thirty years old, and the magnificent and burly Urianhatai rode on the horse and said to Subutai: "Abu, my son is gone."

Subutai said in a deep voice: "The Jurchens can't hold on anymore. I hope you can bring me good news today."

Urian Hatai didn't say much, and his right hand clenched his fist and hit his left chest hard. Then he turned his horse's head and ran to the five thousand troops waiting for him. He drew out a scimitar and raised it high, shouting: "Warriors, go to warriors."

The Urianha Tai tribe was the vanguard, with only a small number of guards being cavalry, and the others were infantry. Because of the attacks and the passes, the cavalry had no place to use their power.

Subutai will lead the main army as the rear army to support it, and most of the main army is composed of cavalry. When the city gate is broken, they will ride their horses and start killing.

Tongguan is dominated by the important areas of Qin, Jin and Henan provinces. The terrain is very dangerous. There is Qinling Mountains in the south, Qiangu in the southeast, and Twelve cities in the south.

There is Wei River in the north, Luo Erchuan meets the Yellow River and walks down the pass, and the west is close to Huayue. The surrounding mountains are connected by mountains, peaks are connected by peaks, deep valleys and cliffs, high mountains and narrow roads, and a narrow path is connected by a narrow path. It only accommodates a car and a horse, which is easy to defend and difficult to attack.

Tongguan guards the passage from the Central Plains to Guanzhong and the Western Regions, and has an extremely important strategic location. It has always been a battleground for military strategists and is known as "the throat of four towns and the 100-2 gates".

The Hundred and Two Pass means that as long as two people guard it, they can withstand the attack of a hundred people. Although this is just an exaggerated description, it is like a man who serves as a pass and no one can open ten thousand men, but it can also show the danger of the terrain.

Since the Tang Dynasty, this pass was renovated and a city wall fortress was built on the pass. Although the pass was widened, it became even more difficult to conquer.

In the past, when there was only one narrow pass, it was certainly impossible to advance in large numbers, but the defending party was also inconvenient to arrange defense. After the city pass was built at the pass, a large number of defensive forces could be arranged and the equipment to be placed.

The Jin Dynasty's Tartars had only 3,000 people, but they withstood the attack of the Mongolian army's 20,000 people, relying on this everlasting pass.

But in the end, the number of people is too big. The Mongolian army can rotate and continue to attack and calmly replenish the weapons and supplies, but they can only consume and have no time to replenish them.

At that time, the two armies had been fighting against the offensive and defense for more than half a month. The underpass was full of broken guns and spears, blood and bones, which showed the tragic war.

Today, less than half of the Jin Tartar defenders remained, and everyone was exhausted. The rock-rolling wood boiling oil arrows used to defend the city had been exhausted, and they could only defeat the Mongolian army again and again with their condescending advantage.

But the Jin general Wanyan Heda looked at the soldiers who were sleeping with swords and guns and leaning against the walls, and knew very well that if reinforcements were not yet available today, the breakthrough would only be in the evening.

As Chen hour approaches, the Mongolian army comes as promised, because they can get enough rest. At this time, they are full of energy, murderous aura, and their iron armor is clanging, and their army is extremely strong.

The soldiers of the Jin Kingdom were woken up by the generals, dragging their tired bodies, opening their red eyes, and getting up and clenching the weapons.

Wanyan Heda sighed. Now that the Mongolian army has attacked the key points, they don’t even need Hui Hui artillery because there is no need.

The basic routine of the Mongolian army's attack was to first set up Hui Hui cannons and fire stone bullets at the city gate to suppress the soldiers guarding the pass so that they dare not show up. Then the soldiers carrying the cloud ladder would take the opportunity to quickly approach the city gate, put the cloud ladder on the wall, and the ants would attach themselves to it.

Because the archers were suppressed by the Huihui cannon, the infantry could reduce many casualties when they rushed to the city gate. But Urianhatai knew very well that the other party had no arrows, so naturally there was no need to suppress them anymore. Just go up and start working.

The battle began soon, and the Mongolian soldiers carried the ladder and rushed towards Chengguan with great swagger. They bit the sword with their mouths, and set up the ladder and climbed up.

The Jin soldiers could only hold a log together and yelled and tried hard to turn the top of the cloud ladder, but the effect was minimal. After the cloud ladder was turned over, the Meng soldiers who climbed up to the top of the cloud ladder were broken, but not many were injured. Then the cloud ladder would be brought back.

After such an attack and defense, the Jin soldiers were greatly reduced. They could no longer lift the ladder, so they had to guard the ladder and stab the Mongolian soldiers who were climbing up with their spears.

The Meng soldiers were fearless and put the Meng Tie shield on their heads with one hand, grabbed the cloud ladder with the other, and climbed up desperately with a scimitar in their mouths.

The few people in front of them resisted the assassination of the Jin soldiers with their bodies, forcibly pounced on the city wall, regardless of their own injuries, and slashed with scimitars. If the first one climbed up, there would be a second one. Soon the city gate was covered with Mongolian soldiers.

Wanyan Heda held a long-handled machete and slashed wildly with a group of personal guards, but there were more and more Mongolian soldiers in the city gate. Seeing that things were not done, he had no choice but to order a retreat.

Seeing that there was no more Jin soldiers in the city gate, Urian Hatai finally showed a happy smile on his face. He called a messenger and ordered him to go to the rear to report that Tongguan had been broken.

The messenger took the order. After a while, the gates of Tongguan were closed wide, and Mongolian soldiers rushed into the pass like a tide. Urianhatai drew out a scimitar and shouted: "The whole army attacked."

"kill……"
