Soon there were words from outside for the people to help shout, and they would come back in a while.

The people outside laughed, thinking that this thing was too funny, and it was blown away by the wind, and it could fly back by itself.

But the foreign envoys did not find it interesting, and their hearts were completely cold.

The ball is not finished when the rope breaks, the rope is tethered to watch.

How far can this thing fly? Will it fly all the way to the imperial city of your own country?

Then throw down the torch or something and fly back to Datang?

Datang has made thousands of such balls, what should I do in my own country?

The people with the ten Turkic surnames and Zhu Xie Jinshan also stood outside and watched, and the people with the ten Turkic surnames pondered whether they could borrow it, and then called back.

Zhu Xie Jinshan wondered if he could use it in his own clan.

Let's not talk about fighting, if you can fly from there to Datang and pass news back and forth.

And the stronger the Tang Dynasty, the better life in his clan.

The people were cheering, and Yu Lin Fei was fine under the big ball, and he couldn't fall at all.

The height can be lowered, and it can be flown up again, not to fly high and drag it down with a rope.

The ministers of Hanyuan Hall are not in a hurry to work, wait, wait and see if they can come back again.

It's just that it's too hot outside, and there's no shade, so it's good to give tea to drink.

Yao Chong was excited, he didn't know that hot air balloons could fly around.

If you don't bring a rope, a large group of hot air balloons, constantly adjusting their direction, attacking the enemy's formation, causing the enemy's mess and casualties.

"Your Majesty, hot air balloons can fly within a general range and can participate in battles and deliver supplies on the battlefield.

I just saw that when I was at high altitude, I flew very fast, and I was not limited by the terrain.

Our Datang should manufacture in large quantities, send elite troops to operate, and go to the border to boost the people's morale and morale. ”

Yao Chong knew how powerful the hot air balloon was.

At the same time, it is clear that the hot air balloon cannot be in the hands of other armies, but can only be controlled by Yulin Fei.

Li Longji is beautiful, the hot air balloon is made, and he doesn't need to take money outside.

Li Yi still has a 10% heaven and earth dividend, and it just so happens that Li Yi wants to find a way to use it.

Hot air balloons are really dangerous and can't be placed in other armies.

Lu Huaishen was silent, he knew that it was difficult to imitate, and he completely relieved his heart.

Sit there and drink tea and wait for the hot air balloon to come back.

A flying object that can adjust its direction on its own can be as scary as it can be.

I believe that many Gentiles who have grass on the wall will know how to choose when they understand the situation.

Zhang said that he borrowed a telescope to scan the sky and wanted to see the figure of the hot air balloon.

As he looked at it, he said, "How long does the fuel for the lighter in there last?" What is the maximum amount to bring at one time? ”

Li Longji was in a good mood and gave the answer: "It depends on how big the hot air balloon is, the weight of the hanging basket is light, and there are more things that can be carried." ”

"Please choose a short and thin person to operate and reduce weight." Zhang said and said.

"Hmm!" Li Longji bowed his head.

There is a short-headed sergeant in the Yulin Flying Cavalry, and his low height does not mean that he has little strength.

Some of the shorter ones who were chosen were able to shoot a strong bow and shoot accurately, otherwise they would not have been chosen.

This kind of person is suitable for hot air ballooning, with accurate bows and light weight.

After the hot air balloon rope is fixed at a certain height and is relatively stable, the archers above have room to play.

Wait until the arrows run out, then drag them down to replenish them.

The other courtiers were as happy as the people, and they were not foreigners.

The hot air balloon flew over, swished away, swished up, and floated down slowly.

Except for the slow descent speed is a disadvantage, everything else is an advantage.

However, slow also has the advantage of being slow, allowing the person above to adjust their ground attack, as long as it rises fast.

"Your Majesty, the minister came up with an idea of fighting with a hot air balloon." The soldier's squire stepped forward.

He exclaimed, "The enemy army is not all crossbowmen, but also spears, swords and shields, baggage, and troops carrying siege equipment.

Hot air balloons can be lowered in height when they are above them, and arrows can be shot at a distance of several feet.

When their crossbows reacted, they immediately raised to dodge, but beware of being ambushed when they were familiar. ”

"Good!" Li Longji praised, yes, everyone thinks together, how else can they play.

According to Yi Di, mastering the hot air balloon means mastering air supremacy.

An army with air supremacy is crushed in the face of enemy ground forces that do not have air supremacy.

As long as the air force is on a large scale, there is no situation in which the ground forces cannot be contained.

Li Longji may think more about whether what he said to others is right, but Li Yi's words, he directly thinks that it is right.

Li Yi never talked nonsense about people's livelihood and military affairs, nor did he brag.

"Your Majesty, the minister also has ideas." And there stood up a squire, from the Ministry of Works.

"Chen thinks that the color of this hot air balloon is too conspicuous, and for military use, it is best to paint it black, which is more concealed at night." He said in terms of color.

"Good!" Li Longji bowed his head, he had already known that the army was going to change color, and the grassland was blue and white, like the sky.

Or the grassland is painted green, and it is not easy to be spotted when it comes close to the ground.

The color at night is not pure black, and there are torches and lanterns on the ground, which can easily be seen when facing pure black.

Li Yi said this, and now the minister is trying to think hard and have to be encouraged.

So the ministers spoke enthusiastically, and some said that they would bring powerful fireworks up and blast them down.

When facing the enemy cavalry, there was a boom, and the horse was startled.

Some ministers said that when there was no contact war, hot air balloons could be sent in advance to carry highly toxic forage.

Take advantage of the night to feed the enemy passing by in the air, and the horse is not in good condition even if it is not poisoned after eating.

It was also proposed that it could be after the advance army of the enemy passed through a certain ravine.

In the evening, the hot air balloon carried the soldiers to the sides of the valley to ambush and transport them several times.

When the Chinese army behind thought that the forward had cleared the ambush and passed, they suddenly attacked and caught the enemy's Chinese army by surprise.

Usually a sanctimonious minister, after the hot air balloon came out, all kinds of conspiracies and tricks came to mind.

Li Longji asked people to write it down carefully, regardless of whether it is useful to look at it now, it is also an idea.

When the time comes, give Yulin a flying ride and let them use it flexibly.

When everyone came up with an idea, Zhang Shuo shouted: "It's back, the hot air balloon is back." ”

"Quick, send someone outside, if you run over the street again, shouting for them to come down, we will answer." Li Longji commanded.

He was afraid that the route would not be adjusted properly, and the hot air balloon would run again, leaving a message of 'we will be back in a moment'.

Everyone looked up, and after a quarter of an hour, it was estimated that they were proficient, and the hot air balloon adjusted its altitude from the side and flew over with the wind.

This time there was no sudden slanting wind, and the two of them actually adjusted their positions, which was not easy.

Seeing that he was about to arrive at Hanyuan Palace, the sixth man above shook his hand and threw down a small part of the rope, shouting: "Hold on to the rope, it's too cold in the sky, ah!" ”

Da Lu turned the fire to a small size, and did not dare to extinguish it, for fear that the speed would be too fast when he landed.

The Qianniuwei below rushed over to the group and grabbed the rope like a tug-of-war.

The flames of the alcohol blowtorch on the hot air balloon fluctuated and were stabilized by the rope and held up.

Then the man pulled it down, and the balloon was still full.

With a 'bang', the hot air balloon landed smoothly.
