"General Lu, are you sure this distribution map is useful?"

Liu Qingfeng was in the temporary command room, holding the results of the measurement on the hot air balloon, and was nervous.

The current situation is that Jiannu has engulfed a large number of Han people in the fortifications outside the city, and the usual artillery battles cannot be used.

If the information fed back from the air is based on the direction of the artillery attack.

But the consequences of doing so are dangerous.

Under an indiscriminate attack, a slight mistake will cause a large number of innocent people to be injured.

"Commander Liu, don't worry, we have received professional training!"

Lu Da seemed very confident and pointed at the people around him: "My skills may not be good, but our Daxia craftsmen are very excellent.

Tested on the grasslands before.

There is absolutely no problem calibrating the cannon with a hot air balloon!”

Lu University then did several popular sciences.

When soldiers on hot air balloons draw coordinate diagrams, they can clearly see the dynamics of the enemy in front of them at high altitude.

The location where the cannon is dropped can be absolutely controlled.

Even if there is no wireless communication tool, it can still solve many difficulties according to the good flag-word.

This is like World War II in later generations.

In the wars in the Far East, people usually remember that the Japanese countries had strong ships and powerful guns, and during the early plundering process, the firepower was very strong.

In fact, in the early days, Japan's energy production was insufficient, and in the early days of the plunder, many old artillery from the Russo-Japanese War (1904-1905) were used.

They can achieve precise strikes because they strive to develop precise observation methods and are good at using hot air balloons to adjust shooting.

"Lu Da, you have thought about it. There are our sects in front of you."

Liu Qingfeng reminded him again.

He also knew that for artillery, the biggest impact was the obstacle to vision by the terrain.

But when the cannon is opened, who can completely guarantee that there are no omissions?

Jiannu now grasped this point, built fortifications, deployed troops, and carried slaves.

No matter how accurate the artillery is, there will always be ammunition falling into other trenches.

But Lu Da finally sighed and said, "War is cruel. If we retreat, we will only die more people.

According to the past, when Jiannu was carrying Han people, the distance was one or two hundred steps.

Besides, if you have installed informants in the slaves, you will have a response at that time, and you can only minimize the accidental injury..."

"That's true."

......

One-night consultation.

the next day.

At the top of Shengjing City, the war drums beat.

Inside and outside the city, the double hits seemed to have already decided to fight today.

The angry Huang Taiji roared in the pseudo-imperial palace. He hated the heaven, but he could not go to heaven.

The harassment of the hot air balloon stopped.

Kong Youde was stunned when he looked at the flying ball in front of him.

Today's hanging basket did not enter Shengjing, but instead stopped in front of the position.

"Press up, push up!"

Kong Youde hurriedly issued orders.

Hundreds of Baoyi Aha in the army began to drive away Han slaves.

Wander in front of the position.

Tens of thousands of people seemed magnificent, and the trenches on all sides outside Shengjing City were rolling up dust.

The Han army behind the meat shield rode a war horse and followed behind and drove away.

There are certain intervals between slaves, military commanders, and Han troops to provide room for buffering.

A few miles away, most of the cavalry of Dorgon and others.

Waiting for the fighter planes at any time to launch a flanking assault.

After all, there are still too few Tianwu Army. Normally, it is impossible to take care of all sides.

However, the existence of iron chariots can make the position as strong as a fortress.

Slave camp, inside the trench.

Zou Dahan was holding a wooden fork tied with a stone knife in his hand. This was the charge equipment given by Jiannu.

Even worse, there are only wooden sticks and hoes.

And war is indeed cruel.

In the changing history, people are always able to talk about the battles that occur at all times.

But few people know that the innocent lives that disappeared behind the war are like weeds cut off, no one cares, and there is no trace after death.

The Jiannu, who had no choice but to adopt the same fighting style as the bandits in the Central Plains, and to entangle the slaves in front.

A mere hundred thousand people are just passing by.

This land of Liaodong has been cut off too much life in the past few decades.

Jiannu's military discipline was strict and he was usually good at using a small number of people to control most of the prisoners, and he took advantage of the fear of slaves.

"It should be soon!"

Riyuan suddenly whispered.

As long as you lead this clan out of the sea of ​​bitterness, you will be able to get big fish and meat when you go back.

The two of them fantasized in their minds.

At this time, a shell fell from the sky and hit the trench not far away, causing a burst of smoke and dust to rise.

Some slaves and Baoyun died and a blood mark was released, but the injured ones must be innocent.

"Damn it! I really think it's a teacher of justice!"

Kong Youde laughed at it.

The Han army hid behind the slaves and hid the body of the large army.

The Tianwu Army could not see the troops, so at the beginning, they could only fire artillery blindly.

In the camp of Han slaves, a group of people suddenly became messy. Someone was about to retreat and escape when they were chopped off by the military supervisor from behind.

And this is just a corner of the battlefield.

In just a moment of commotion, nearly a hundred lives disappeared.

Life is like grass.

At this time, over the hot air balloon, it was easy to see that under the control of the Han army and Jiannu, the slaves on the position were divided into four areas.

There are obvious boundaries in the mess.

"Twenty steps left, four or five corners... Launch!"

At this time, the Tianwu Army artillery had a strong face and was completely adjusted according to the information conveyed in the sky.

Everyone held their breath and condensed their breath.

The shells crossed the trench this time, and the hot air balloons hovering in the sky could see clearly.

Every time the ground is repeated, the rest must be repeated, and then launched.

The Dorgon flag soldiers in the distance looked at the Han people on both sides as if they were watching a show.

Kong Youde had already felt a little bad at this time.

"Fire the gun! Fire!"

"fight back!"

Kong Youde ordered the Han army's artillery to fight back. Now under Shengjing City, there is no need to worry about transportation. Their artillery and ammunition are naturally sufficient.

But why are the two armies far apart.

The Han army's smoothbore cannons were not used for long-range use at all. They copied them according to the rules, but their technical foundation was not good.

To be honest, it is like barking incompetence.

It was possible to barely hit several miles, but it was not accurate to hit it. Some shells simply landed in their own trenches, taking away all the Han people.
To be continued...
