On April 18th, the weather is clear.

Many people don’t understand what the meaning of Li Longji’s small dynasty meeting was.

After the court meeting was over, Li Longji announced: "There is a new thing called a hot air balloon. I will bring one today, and the Yulin Feiqi will demonstrate it to everyone."

Everyone was in a state of great enthusiasm, and today they could actually see the rumored flying ball.

Everyone was waiting, Yulin Feiqi led four horses here, and immediately carried the box.

Use this to tell the ministers that hot air balloons are easy to carry.

Then Yulin Feiqi opened the box to get things, quickly assembled it, debugged it, bulged the hot air balloon, and the two of them went up to control the alcohol blowtorch.

The hot air balloon gradually rose under the gaze of the ministers. When it reached thirty feet, everyone inside and outside the palace saw it.

The people stopped and watched the road in front of the imperial city. The distance was closer and they could see clearly.

A large basket was hung under the colorful balls, and there was a Yulin Feiqi in the basket.

The hot air balloon continues to rise, and the hearts of envoys from various countries continue to sink.

I saw it and saw it clearly. I can indeed carry people. Is it still carrying the Yulin Flying Cavalry? What does the emperor of the Tang Dynasty want to express?

When the hot air balloon used up two hundred feet of rope and moved with the wind in the sky, the cheers of the people came to Hanyuan Hall.

Officials gathered together and whispered.

"Take out the good stuff, even if you don't use it, the envoys from other foreign countries will pass it back after seeing it, which will scare them to death."

"It is the best time to attack the city. You can choose the wind direction. If there is one wall on the city guarding the city, the other two sides will be slanted, and only the surface can be extended out."

"It's not good to be strong, and the rope suddenly broke. The person on it was blown away and fell to death."

"There is no one who can't die in a war. Killing from falling is normal casualties."

"How long can the rope be added? The rope also takes up the same amount of weight when it grows."

"There are no weapons that cannot be found. It's already good. With more hot air balloons, it is an auxiliary to other troops."

"That's right, can't you defend the city without hot air balloons? Even if you can only slow down the pressure on one wall, the defenders on this wall can reinforce other walls."

"You can still look at it, two hundred feet high, and use a telescope to see the enemy's arrangements."

"Yes, one above looks at it, and the other is chanting the flag."

"The soldiers from the border must be very happy to know."

"It's not expensive to build things?"

"It's expensive to build."

The ministers expressed their opinions.

"Your Majesty, is this thing time-consuming to make? It's better..." Yao Chong was close to Li Longji, and he asked if it took time to make it.

Before he could finish speaking, Li Longji interrupted him: "No, the Li family village can build it soon."

"Faster than making a bow?" Yao Chong wanted to know.

"The bow takes a long time, and the crossbow is longer. A hot air balloon is actually not as cost as a strong crossbow."

Li Longji finally gave a clear idea.

The strong crossbow process is many, the time is long, the hot air balloon is simple, the working time is short, and it is not considered technical money, so it is naturally cheap.

"Ah?" Yao Chong was surprised. He thought that a hot air balloon would be worth a thousand silk.

The result is cheaper than a strong crossbow, and the cost of a strong crossbow of fifty or sixty pieces is normal.

"Then...then..." Yao Chong didn't know how to express it for a moment.

"It's broken, the rope is broken, it's broken about ten feet." A shout suddenly came.

Everyone looked down, and sure enough, the rope fell and the other ropes flew away with the hot air balloon.

The ministers were anxious. Today they were going to kill two Yulin Feiqi?

Li Longji frowned.

"Your Majesty, there was a sudden gust of wind just now, and the rope broke." Xiaohuangmen ran over to tell the reason.

All those who watched the hot air balloon were now confused, and foreign envoys were excited.

It turns out that there are shortcomings. Once the rope is broken, the person will fall to death.

The ministers of Hanyuan Palace looked at Li Longji. Li Longji thought about it and ordered: "Get tea and wait for the hot air balloon to fly back."

Ministers: "…"

The rope was broken and blown away by the wind. Can you still come back? Then why do you need the rope? Your Majesty is afraid that something went wrong after being anxious?

At this time, the two people on the hot air balloon encouraged each other.

"Lao Liu, don't be afraid. We said that we can change it, hurry up, put the rope up, let's find a way to fly back and don't fall into the wild."

A sergeant shouted.

"I know Dalu, hurry up, raise the wind direction is wrong." Lao Liu pulled the rope frantically, stretching and shrinking his arms, one by one (tuo the distance between his arms and two hands).

Crack into bundles skillfully to avoid being confused and difficult to resolve.

Dalu gives fire, and the hot air balloon rises rapidly.

When you reach a certain height, the wind direction changes, but it does not blow back, so continue to pull up.

"A little cold." Lao Liu was still standing upside down.

"The higher the higher the more, it's okay, the boss said, "The rise is 333 zhang and the temperature drops by six degrees, we can persist." Dalu explained it with science.

"If I had known to wear a cotton coat, wouldn't I be able to breathe even if I had high enough?"

"Then go down, you can't be suffocated to death, at worst you can go to the wild."

"It's changed, fast, just this height, I'm back, oh, it's not easy, but it's really OK."

"It will be easier to deal with in the future. Bring clothes in the basket and bring the owner's oxygen bag."

After operation, the hot air balloon ushered in a new wind direction at an altitude of more than 3,000 meters and blew back.

Fortunately, it was summer, the temperature dropped by twenty degrees and could still withstand it.

The two of them discovered the new world, my goodness! You can look for the wind, who said that the hot air balloon can only fly in one direction?

What is the use of this rope?

The two of them flew back, and Li Longji was waiting.

Whether it is flying back by himself or sending news after landing, there will always be someone back.

Li Longji didn't believe that the Yulin Feiqi would fall to death, and the hot air balloon would no longer be fired, so the height would be reduced.

After waiting for about two quarters of an hour, a Gao Lishi, who was looking around with a telescope, shouted: "I saw it. It's very small in the sky, floating over, getting closer, and reaching our heads. Oh? It's over."

Li Longji stood up, took the telescope, and sure enough, he saw a small balloon flying in the other direction.

Then the balloon was falling, flew to the left, then fell to the left, rising, not left, but right, flying for a distance, falling.

As the height decreases, others will find it without using a telescope.

The hot air balloon that was watching it grow smaller rose and lowered sometimes, and it was gradually approaching here.

After waiting for another two quarters of an hour, the balloon was getting bigger and I could see the hanging basket and the people inside.

The hot air balloon descends to the height and is blown back by the wind.

The people cheered, the messengers were very depressed, and they could fly back and forth without ropes?

Li Longji smiled. Sure enough, the Yulin Feiqi was the calmest and was not afraid of unexpected situations.

When looking at the route of the hot air balloon, it floats towards Hanyuan Palace.

The group waited excitedly and waited for the ball to land.

The person I saw at this time was closer than when I was at the highest point just now.

Many people sweat on their palms, probably because of the hot weather.

As we got closer, we suddenly felt a strong wind blowing slanted, and the hot air balloon floated away six or seven meters high from the ground.

The hot air balloon floated over the avenue in front of the Imperial City, and a shout came from above: "Tell Your Majesty, we will be back in a while. Oh, this wind."

The people watching below saw such a big thing flying over their heads, and heard shouts, and many people said: "Oh~~"

The hot air balloon quickly lifted up again and went away.

"Wait a little longer." Li Longji said helplessly.
Chapter completed!
