With the advent of new weapons, especially fortifications, barbed wire was like a wall that could effectively defend against large-scale onslaught of infantry and cavalry. At the same time, the advent of machine guns made it possible to quickly shoot the limited number of opponents. In particular, the advent of artillery, coupled with concealed fortifications, multiplied the huge attack power of artillery. Mass destruction of opponents' soldiers became possible. It also becomes an easy thing. A single shooter can easily kill hundreds of attacking soldiers as long as he hides behind the fortifications.

The advent of advanced weapons has given the defending side a greater ability to conduct defensive operations. In particular, bulky machine guns played an important role in defense.

But the other weapon gives the attacking side great destructive power. This is what heavy artillery is. Heavy artillery was all over five inches in caliber. These cannons are fired at a longer range than the old guns, and the power of the attack is immensely greater due to the use of yellow explosives.

"Retreat. Fall back. The Yan soldiers began to turn around and run.

"Give me back, you keep shooting for me. Shoot alternately and retreat, don't turn around and run. "When a Yan officer saw a soldier turn around and run quickly, he grabbed him and told him to shoot, even if it was Qin training. These recruits will also quickly forget what they have learned in the environment of the battlefield, and in their eyes, what they have learned is just a game of war.

In this way, the Yan army retreated while fighting.

"Bang. Boom. Whew, whoosh. "Artillery shells whizzed by.

"Bang." Then a loud bang rang out. Then there was a splash of fire, like lightning and thunder, and finally a cloud of smoke rose one after another.

"Boom." The earth began to tremble. The retreating Yan soldiers watched in horror at the bombardment of heavy artillery. The flames continued to shine on the faces of their soldiers, who had little experience in warfare. One could only see on their faces the awe that had not experienced war.

"These big guys are too powerful." A Yan soldier said.

"Hey, hey." The veteran could only smile slightly. He's been through such a battlefield.

"I haven't experienced such a big artillery attack, though. But I've been through something worse than that. The veteran began to tell his story as he spoke.

"When I was a soldier in the Yan New Army, we had to attack in a row. At that time, the bullets were not allowed to hit. "There was soon a large crowd of recruits around the veterans, who wanted to be able to draw on the story. to divert their sense of awe and fear of the cannon.

"A bullet at a distance of eighty paces will not hit us at all, but within fifty paces, a platoon of guns will kill a lot of people. If you shoot within thirty paces, you will die more. I saw with my own eyes how the powerful bullets pierced through people's flesh and how blood splattered. The veteran said.

"When did this happen?" One of the recruits asked curiously.

"At that time, our Yan State was still at war with Zhao State. That's how we beat our opponents. At such a close distance, we could all see each other's faces, unlike now, where we were sometimes killed even if we didn't even look like each other. I don't know who killed him. That's the damn war. The veteran said. War is indeed brutal. And it's very brutal.

The veterans themselves reminisce about the past. When veterans were soldiers, it was still the era of platoon guns, and that kind of tactic required great courage and discipline to do this, even if the people around them fell one after another, they couldn't watch it. It's about keeping moving forward, moving on, moving forward. Only in this way can there be a good chance of survival. Those who fell were quickly replaced by those behind, and all the soldiers had only two shots at most, whereas before, they had to let their opponents shoot as hard as they could, and they had to advance at this inaccurate distance. Keep moving forward.

Only when they reach the position of the optimal combat distance will they stop, and then shout loudly with neat slogans. Aim. Shooting, in a row of shots. Most of the opponent's personnel were hit and fell, and then three rounds of fire began, and by the end of the day, the opponent had to fall a lot of people, and then the charge. Kill with bayonets those who were shot by three rows of muskets, who were broken in their will.

"The scariest thing is not the platoon of guns. It's those cannons. As long as those cannons are fired at a high enough density, we can sometimes just move forward. The veteran said.

"Have you ever seen a cannonball slicing off someone's head? I've seen it, it's a ricochet, seen through a telescope. Those cannonballs seem to be very slow, and you can reach out, but they are not very good things. The veteran said.

"As soon as the shells landed, a large number of people fell, and those people died very badly. I walked over and looked at it. The whole flesh was smashed. Bones, guts, and something else. All in all, it looks very disgusting. The veteran continued.

"The shells then hit the hard ground and bounce off. Cannonballs will fly over our heads. All we can say at this time is that. Oh my God. That's lucky. ”

"But the place where it landed was not so lucky. When the shell falls again, a lot of force is generated. That force can easily knock a person's head off. I saw that a soldier's neck was just so easy to knock down. And then a headless corpse was born. The veteran recalled.

"And that head, what's going on with the head?" One of the recruits asked in surprise. He apparently wondered what would happen to his head after the shell hit.

"Head. Hahaha. Head. The veteran said with a sudden laugh.

"The head, it will become like water. Just if, a ball of crumbled eggs. At this time, the recruits can't laugh even if they want to. His head was like an egg in front of a cannonball. This is really unacceptable to them.

"Then it was the machine gun. That thing is the most terrifying, chasing us. The veteran shook his head. He really didn't want to remember anything. After all, war is cruel and not a very interesting thing.

At this time, the short artillery attack ended, and the Yan soldiers began to reorganize and attack under the reorganization of the officers.

"All bayonets and new attacks. Give me a good performance. Don't be ashamed. The officer said back and forth.

"Damn it, I wish his head was a broken egg." One soldier said maliciously.

"Hey, hey." The other soldiers laughed dryly. Aren't our own heads eggs? These recruits began to rethink the brutality of war.

"It seems that the power of heavy artillery is still very great." Wang Jian said happily. After a heavy artillery bombardment, the bunker fortifications over there were almost blown up. And the Yan army, following the armored fighting vehicles, finally occupied the opponent's position.

Artillery bombardment, coupled with the charge of infantry and armored fighting vehicles, such tactics should do. However, the firing level of the heavy artillery units of the Yan army was very limited, and it could only be completed with the help of the Qin army.

"If the war can continue according to this pattern, I am afraid that we can let the Qi army go to the Qi country." Wang Jian said to a senior officer of the Yan Army.

And the officer of Yan Guo nodded in approval, for the rest, he didn't say anything, there was nothing to say.

"Alright, here's a telegram from ahead of you. Looks like you're going to war soon. At this time, Wang Jian took out a telegram from his pocket and handed it to the Yan State officer. After the officer of Yan Guo took it, he looked at it and put it away. This is a telegram of the expedition. The content of the telegram probably meant that they should obey the arrangement of the Qin army as soon as possible, get on the train from Xianyang, and then march towards the war zone. They want to be fast. Because the war situation is very unfavorable to Yan State.

And the situation in Yan is indeed very unfavorable, to what extent is the unfavorable situation. That's only known to the Qin pilots.

"Buzz." A Qin Guoying twin-engine two-man fighter flew over the heads of a fast-moving Qi army.

"No, it's a bird. Hide, everyone. A man who looked like an officer of the Qi army was alert to the sound of humming in the sky, and looked up at the sky. As a result, when he saw it, he was startled, there was a plane of Qin State in the sky, and they knew that Qin State's plane was very annoying.

"Spread out, spread out quickly." The man who looked like an officer of the Qi army shouted quickly and loudly.

"Spread out." Some of the veterans began to shout loudly.

"Buzz." At this time, the fighters of the Qin State had already begun to dive down towards this group of Qi troops. The two machine guns in front were enough to form a powerful firing surface. Pilots generally think so.

In the face of the ground attack of the aircraft, the infantry has no good way, even if it is shot with a rifle, it cannot form a great killing effect. Bullets can only make a small hole, that kind of specialized anti-aircraft weapons, they have not yet appeared.

The Qi soldiers slowly dispersed to both sides. But at this time, it seems to be a little late.

"Buzz. Call. "The plane whizzed by.

"Bang bang." A series of machine-gun sounds rang out, and bullets whirred to the ground.

A Qi soldier was hit, and then made a terrible ** sound.

"Woo". The plane was quickly pulled up.

"Bang bang bang. Bang bang. Bang bang. The pilot in the back, who was an observer, operated the machine gun in the back and kept firing at the Qi soldiers on the ground.

Although this strafing is not very effective, it can create a sense of psychological fear in the escapee. "Run." A Qi soldier shouted loudly and anxiously. They were terrified of this kind of airplane stuff.

"Do we need to fly another lap?" The Qin pilot with goggles shouted loudly.

"No, look at our fuel and bullets, we can't do it again. We're heading back to base. The pilot of the plane replied loudly.

"Okay, that's all for today. Today is really a day for the Qin Heavenly Army to celebrate, we actually strafed two ground forces of the Qi Army. The pilot shouted.

"That's true." The pilot in front shouted loudly. This is indeed something to celebrate for them, but for Yan Guo, it is not so easy. On the contrary, they felt very stressed.

After the Qi army captured the Yan army. All of a sudden, the situation became clear. At this time, Yandu was less than two hundred miles away from the outpost of the Qi army, and this distance had already entered the position of the Qin Heavenly Army patrolling and defending, but for Yan Guo, it meant that they did not have much time.

Between the Qi army and Yandu, there is no Yan army that can resist the rapid advance of the Qi army, which means that it is only a matter of time before Yandu falls, and now it depends on how long the time can be.

But there was another army in front of them, and this force was several airfields of the Qin State, and in addition to the airfields of the Qin State in Yandu, there were two airfields deployed in the middle of this position.

However, it should be noted that the number of aircraft at these two airfields in the Qin State was very limited, and the combined number of aircraft was less than twelve, but the ground forces were more than a battalion of marines for defense. They were the only troops on this distance that could fight.

With the complete victory of the Qi army and the rapid advance of the Qi army, the Qi army gradually entered the air patrol range of the Qin Heavenly Army. Every day, pilots found a large number of Qi soldiers, and many of them used machine guns to strafe these Qi soldiers on the march. The Qi soldiers were harassed by more and more Qin planes, but this harassment was only a temporary slowdown in the pace of Qi army's advance, because the number of planes was effective, and the troops adopted a more dispersed way of advancing, they advanced with about 500 people as a team, so that the Qin army's air strafing could not kill many Qi troops, and the Qi army also paid more and more attention to air protection, and they always watched the changes in the sky.

"We found three groups of Qi troops today, their size is about 1,000 to 2,000, and we strafed them, but the effect is not very good. The Qi army is still advancing. And they move forward as if they weren't disturbed by us. A pilot second lieutenant reported.

"Yes, I know that." The Qin army's airfield commander nodded in approval. In fact, such reports began to occur frequently in the days following the surrender of the Yan army. In this regard, the commander of the Qin army began to get used to it. However, they began to worry about some problems, and that was with the rapid advance of these Qi troops. Their machines are getting closer and closer to each other. They don't know when they'll be able to retreat. They need to be given such accurate orders.

This kind of worry is very necessary, because as the Qi army advances, the Qi army is getting closer and closer to their airfield, and the Qin army does not seem to have the intention of asking them to retreat, if they want to retreat, then the order will be issued early, because retreat is a technical job. If not prepared, the retreat will become a mess.

But there was no such order issued by the Qin State, and the pilots had to do something on their own.

"We used the machine guns on our planes as much as possible to strafe the rapidly advancing Qi troops on the ground, and they kept spreading out to avoid our attacks. And there is nothing we can do about it, we can only use machine guns to kill every Qi person who advances as much as possible. One of the pilots said.

"We flew over and did a quick strafing fire, and we hated that the machine guns were really slow, but they were very fast. The machine gun struck like a tractor's coulter. Many Qi people who didn't have time to dodge were hit by us, and they were either shot in the head or shot into a honeycomb shape. ”

"That's it, after we're shooting, the other side will still move forward, and it's like a walk, because we don't have ground troops, ground troops, you know? We just attacked them, they only suffered certain losses, but the only thing that could really stop them was the army, but the Yan people had no army to use, and between us and the Qi people, there was nothing, and the Yan people were all gone. The pilot complained.

In fact, it is true that between the airfield of the Qin army and the advancing troops of the Qi army, the Yan army no longer exists. The Qi army advanced rapidly. And the Qin army could only harass and shoot as much as possible. Slow down the opponent to move forward.

However, the ground forces only had one battalion of the Qin army, and this battalion could only be used for airfield defense, not for attack, and they were also insufficient, and one battalion had to defend two airfields separately, and they simply could not spare their hands to attack. They are seriously underwhelmed.

This is the fact in front of the people of the Qin State. And in the Qin State General Staff, the military has not forgotten the two airports of the Qin State, but the problem is that the Qin State wants reinforcements, but the number of airports is only these three, if there are large quantities of reinforcements, it is bound to need the airport to accommodate them, and the Qin State military means that it is necessary to defend as much as possible, and then establish a defense point there, so that more planes can land.

But the other side thinks that this is inappropriate, and this side is represented by Wang Qian, who believes that the current situation is not the time to consider the number of heavenly troops to be sent. Rather, it is necessary to consider the timing of the dispatch of the Zhao army, and at the same time, where the specific location of the defensive line that can be established. This was very important to the Qin State.

Because this line of defense is related to the next deployment of the Qin State, so, considering this, the Qin army gave the initiative to the Zhao army and asked the Zhao army to formulate a specific plan for adjusting the defense line.

It was precisely this kind of thinking that directly led to the fact that the Qin army did not give an order for the evacuation of the airport, or even an order to prepare. The commander of the airfield asked one after another whether to retreat or stand by, but there was no clear answer above, and continued to wait for orders.

In this way, the defenders of the two machines have to constantly wait for the order to be given. This wait had serious consequences, because the Qi army was advancing very fast, and after a continuous advance, a reconnaissance outpost had already discovered the place where the Qin planes had landed at the airfield.
