Soon, the people outside shouted that they would be back in a while.
The people outside laughed and felt that this thing was too fun. It could fly back by itself after being blown away by the wind.
The foreign envoys did not think it was fun at all. Their hearts were completely cold.
The ball was not finished when the rope broke. The rope was just for show.
How far could this thing fly? Would it fly all the way to the imperial city of their country?
Then it would throw down a torch and fly back to the Tang dynasty?
If the Tang dynasty made thousands of such balls, what would happen to their country?
The people of the ten Tujue families and Zhuya Jinshan also stood outside and watched. The people of the ten Tujue families wondered if they could borrow it and then fight back.
Zhuya Jinshan wondered if they could use it in their own family.
Not to mention war, it would be good if they could fly back to the Tang dynasty and send messages back and forth.
Moreover, the stronger the Tang dynasty was, the better their lives would be.
The people were cheering. The Winged Knights were fine under the big ball. They could not fall at all.
They could fly back up again. They did not have to pull down the rope when they flew too high.
The officials of Hanyuan Palace were not in a hurry to work. They were waiting to see if they could come back again.
It was too hot outside and there was no shade. Fortunately, there was tea to drink.
Yao Chong was excited. He did not know that hot air balloons could fly here and there.
If there was no rope, a large group of hot air balloons would constantly adjust their direction and attack the enemy's formation. It would cause chaos and casualties for the enemy.
"Your Majesty, hot air balloons can fly over an approximate range. They can participate in battles and transport supplies on the battlefield.
I just saw it. It flies very fast in the sky and is not limited by the terrain.
The Tang dynasty should mass produce it and send elite troops to operate it. It will boost the morale of the people at the border. "
Yao Chong knew the power of hot air balloons.
At the same time, he knew that the hot air balloons could not be controlled by other armies. They could only be managed by the Winged Knights.
Li Longji was happy. He did not need to pay for the production of hot air balloons.
Li Yi still had 10% of the dividends from Earthly Paradise. Li Yi was looking for ways to use it.
Hot air balloons were indeed dangerous and could not be placed in other armies.
Lu Huaishen didn't say anything. After knowing that it was difficult to imitate, he was completely relieved.
He sat there and drank tea leisurely, waiting for the hot air balloon to return.
A flying object that could adjust its own direction was as scary as it could get.
He believed that many of the opportunistic foreigners would know what to do once they understood the situation.
Zhang Shuo borrowed the binoculars and scanned the sky, hoping to see the figure of the hot air balloon.
While looking at it, he said, "How long can the lighter's fuel be used for? How many can you bring each time? "
Li Longji was in a good mood and answered, "It depends on how big the hot air balloon is. The basket is light, so it can carry more things."
"This subject requests that a short and thin person operate it to reduce the weight." Zhang Shuo said again.
"En!" Li Longji nodded.
Among the Winged Knights, there was a short Non-commissioned Officer. Being short did not mean that he was weak.
Some of the short ones who were selected were able to continuously draw strong bows and shoot accurately. Otherwise, they would not have been selected.
This type of person was suitable for the hot air balloon. The bow was accurate and the weight was light.
After the hot air balloon was tied to a rope and fixed at a relatively stable height, the archers on top had space to display their skills.
When the arrows were used up, they would be pulled down to replenish.
The other subjects were as happy as the common people. They were not people who colluded with foreigners.
The hot air balloon flew over, flew away, whizzed up, and slowly floated down.
Other than the disadvantage of a slow descent, everything else was an advantage.
However, a slow descent also had its advantages. It could allow the people on top to adjust their attacks. As long as it rose quickly, it would be fine.
"Your Majesty, this subject has thought of a way to use the hot air balloon." The assistant minister of the Ministry of War stood up.
He said loudly, "The enemy is not only made up of archers. There are also spears, shields, Baggage, and troops carrying siege weapons.
The hot air balloon can lower its altitude when it is above them and shoot arrows from a few feet above them.
When their crossbows react, immediately rise to avoid it. However, be careful of being ambushed by people familiar with it. "
"Good!" Li Longji praised. That's right. Everyone should think together. How else could they play?
According to Brother Yi's words, controlling the hot air balloon meant controlling the air.
An army with air control would crush the enemy's ground forces without air control.
As long as the air force was on a large scale, there would be no situation where the ground forces could not be controlled.
Li Longji might think about whether what others said was right or not, but he directly believed that Li Yi's words were right.
Li Yi never talked nonsense or bragged about matters related to the people's livelihood or military affairs.
"Your Majesty, this subject also has an idea." Another assistant minister stood up. He was from the Ministry of Works.
"This subject feels that the color of the hot air balloon is too conspicuous. If it is used for military purposes, it is best to paint it black. It will be more hidden at night." He said from the color.
"Good!" Li Longji nodded. He already knew that the army had to change the color. The color of the grassland was blue and white, like the sky.
Or the grassland was painted green. It was not easy to be discovered when it was close to the ground.
The color at night was not pure black. There were torches and lanterns on the ground. When faced with pure black, it was easy to see the reflection of light.
Li Yi said this. Now the ministers were working hard to think about it and needed to be encouraged.
So the ministers enthusiastically spoke. Some said that powerful fireworks should be brought up and shot down.
When facing the enemy cavalry, the horses would be startled with a bang.
Some ministers said that when there was no contact, hot air balloons could be sent in advance to carry highly poisonous fodder.
At night, the fodder could be used to feed the enemy's horses. Even if the horses did not die from the poison, they would not be in good condition.
Another person suggested that after the enemy's vanguard army passed through a canyon.
In the evening, the hot air balloons would carry soldiers to the two sides of the canyon to set up an ambush.
When the army at the back thought that the vanguard army had cleared the ambush, they would suddenly attack and catch the enemy's army unprepared.
The ministers who were usually sanctimonious thought of all kinds of schemes and tricks after the hot air balloons came out.
Li Longji asked people to remember carefully. Regardless of whether it was useful now, it was still an idea.
When the time came, he would give it to the Winged Knights and let them use it flexibly.
When everyone was coming up with ideas, Zhang Shuo shouted, "It's back, the hot air balloon is back."
"Quick, send people outside. If it runs to the sky above the street again, shout for them to descend. We will provide support." Li Longji ordered.
He was afraid that if the route was not adjusted properly, the hot air balloon would run away again and leave a sentence, "We will be back in a while."
Everyone looked up. After a quarter of an hour, the hot air balloon adjusted its altitude and flew over from the side.
This time, there was no sudden slanting wind. The two of them actually adjusted their position. It was not easy.
When they were about to reach Hanyuan Palace, Old Six shook his hand and threw down a small part of the rope. He shouted, "Grab the rope, the sky is too cold, ah!"
Big Lu adjusted the fire to a very small size and did not dare to extinguish it. He was afraid that the speed of descent would be too fast.
The Thousand Bull Guards below rushed over and grabbed the rope. It was like a tug-of-war.
The flame of the alcohol burner on the hot air balloon was sometimes big and sometimes small. After being stabilized by the rope, it held.
Then, people pulled it down. The balloon was still full.
With a bang, the hot air balloon landed smoothly.
