After returning to the barracks, Lu Bu arranged some soldiers to strengthen their vigilance, and all the remaining soldiers went to rest.

Although Lu Bu didn't believe in just Gaoyou City, he still had the courage to steal camp at night.

Lu Bu estimated that Dahua's army was retreating and the defenders in Gaoyou City were all grateful.

However, you must be careful and prevent any situations that may occur.

After arranging everything, Lu Bu went back to his barracks to rest.

As a result, when it was almost dawn, Lu Bu, who was sleeping, was awakened.

"Enemy attack! Enemy attack! Hurry up, be prepared!"

Um?

Enemy attack?

After hearing the news, Lu Bu was shocked.

The Cao Wei defenders in Gaoyou City are really brave enough to attack the Dahua military camp?

However, how many soldiers can the entire Gaoyou City have? Who gave them the courage to come to attack the camp?

Lu Bu did not dare to be negligent, so he got up and got out of bed, put on his battle robe, and quickly walked out of the barracks.

At this time, many soldiers and officers were awakened and were quickly putting on their clothes.

Soldiers were getting up one after another and walked out of the barracks with weapons.

When facing the enemy's attack, the Dahua soldiers' reaction was obviously much better than other troops.

Soldiers remain calm and can still maintain a certain order.

When I came out, I was very consciously lined up and prepared to enter the battle at any time.

Seeing this scene, Lu Bu couldn't help but nodded slightly.

The rank discipline of the people's soldiers is still very good.

Next, Lu Bu patrols the military camp and does not find the invading enemy troops.

But at this moment, Lu Bu saw five huge hot air balloons rising from the city in the direction of Gaoyou City.

Seeing this scene, Lu Bu's pupils couldn't help but shrink slightly.

Unexpectedly, Cao Wei not only stole the recipe of their gunpowder and made landmines, but now he even made hot air balloons.

In terms of air control, Cao Wei gradually followed Dahua.

If Cao Wei's hot air balloons come over the barracks and throw grenades or incendiary bombs downwards, Dahua will definitely be very passive.

After all, Dahua did not make any preparations in advance and did not dig air raid shelters to avoid air strikes.

So, what they can do now is to prevent Cao Wei's hot air balloons from entering the sky above their barracks.

Lu Bu immediately called the members of the hot air balloon team and ordered them to block Cao Wei's hot air balloons.

Soon, the hot air balloons in Dahua began to be launched.

However, Lu Bu still felt that this method was not very good.

Because, the current hot air balloons can occupy the commanding power and can attack the ground from the air.

But there is no effective way to achieve empty-for-empty.

There is no effective attack method between the hot air balloon and the hot air balloon!

You can't use a hot air balloon to hit the other party's hot air balloon!

Or throw a grenade after getting close?

The sky is too vast, and the opponent's hot air balloon can easily go around.

It's really difficult to intercept.

In this case, it is really possible that Cao Wei’s five hot air balloons would enter the sky above his barracks.

If they really come over the barracks, it will be difficult to deal with them.

Evacuate the crowd and then look for bunker to lie down?

But what should I do if there are food and grass in the tent?

If the tent is removed and the food and grass are transferred now, it will be too late to go.

Thinking of this, Lu Bu couldn't help but frown.

At the critical moment, Lu Bu's eyes lit up, and he became anxious and suddenly thought of a solution.

Lu Bu quickly mobilized several teams of soldiers and ordered them to move a hundred three-bow crossbows outside the barracks and standby.

The best attack height for the hot air balloon is about one hundred meters.

At most, it is controlled at a height of about 150 meters. If it is higher, it will be difficult to control precise strikes.

Furthermore, if you want to throw a bomb, how long should the lead of the bomb be?

If the lead is short, it will explode directly in the air and will not pose any threat to the ground.

If the lead wire is too long, it will not explode even if it falls to the ground.

This gives the place time to react.

In order to facilitate the control of the time in between, and not allow the enemy on the ground to attack the hot air balloon to obtain space, the attack height of the hot air balloon is usually controlled between 100 and 150 meters.

A height of one hundred meters, an ordinary bow and arrow can't shoot that high at all.

If you are shooting flat, I believe that many strong men can shoot to this height, even 120 or 30 steps, or even 150 steps.

But if you shoot at high altitude, the altitude will be greatly reduced.

Even if the archer with a flat shooting energy can shoot a distance of 150 meters, it is very difficult to shoot a height of 100 meters from a high altitude.

The key is that even if you can shoot a height of 100 meters, you cannot penetrate Lu silk at the end of the strong crossbow!

It does not pose much threat to hot air balloons.

Once the other party reaches a height of 150 meters, even if Lu Bu holds the bow himself, he will not be able to threaten the other party's hot air balloon.

Before, Dahua's hot air balloon team used this art of distance to beat Cao Wei.

However, Cao Wei had no weapon that could threaten the hot air balloon.

And now, the situation is reversed.

Now it was Cao Wei who was coming to bully Dahua.

However, Cao Cao seemed to have forgotten Dahua's weapon, which was the three-bow bed crossbow!

You know, the three-bow crossbow can shoot a hard crossbow of one thousand steps!

If you can adjust the height and launch it into the sky, even if you fold it in half, you can only shoot a height of 500 meters, or even a 400-300-meter-long discount, which is only 300-400 meters tall, which is more than enough to deal with hot air balloons.

The hot air balloons move at a speed that is not too fast. If one hundred three-bow crossbows were fired continuously, Lu Bu believes that he should be able to knock down the other party's hot air balloon.

At this time, Dahua soldiers had quickly arranged the three-bow crossbow outside the barracks, and obviously thought of this.

Every Dahua soldier showed excitement in his eyes.

snort!

You Cao Wei has no way to deal with our hot air balloons in Dahua.

Now that you, Cao Wei, have also made hot air balloons, will you naively think that there is no way for us to deal with your hot air balloons?

Then you are too naive, right?

Under Lu Bu's order, the soldiers quickly adjusted the angle of the three-bow crossbow.

Direct 90-degree vertical shooting is not reliable.

Not to mention how difficult it is to shoot, even if the hot air balloons in the air can be shot down, the falling crossbow arrows and the falling hot air balloons will easily hurt themselves.

Therefore, Lu Bu decided to adjust the elevation angle of the shooting to an inclination of about seventy or eighty degrees.
