Chapter 389 Another Item Is Unavailable

Regardless of the hostile relationship between Tibet, Turks, Khitan and the Tang Dynasty, they still have people in charge of diplomacy in the Tang Dynasty.

Naturally, diplomats were responsible for intelligence gathering.

In the past, most of the information they collected was about a certain official or a certain relative.

Including things in the palace and what the emperor of the Tang Dynasty liked.

Starting from last year, the intelligence they collected pointed more towards Li Jia Zhuangzi.

He said that Li Yi had brought out something that would benefit farmers the day before yesterday. He would draw the drawings himself and send someone to send it back. He could not bring the actual items with him, as he would be stopped.

He said that Li Yi had taken out something yesterday and continued to draw the drawings and send them back.

He said that Li Yi asked the people to go chipping away at the ice today to make money, as well as tools for standing more firmly on the ice and tools for drilling through the ice.

It is said that Li Yi asked the people of Chang'an to knead mud to make money. The people's lives were better and they had spare money.

It is said that the fireworks made by Li Yi can be used in the military to blow up enemies. They are very powerful, but if you buy them, you can only be watched and set off.

It is said that Li Yi rushed to Henan Prefecture with the chickens and ducks on Zhuangzi. There was a locust plague in a large area east of the Taihang Mountains, and the chickens and ducks were dealing with it.

Not even two days had passed before something even scarier came out. Li Yi made a big ball that could carry people flying into the sky.

How could the envoys sent by various countries not know what the common people can think of?

This big ball can kill people. The Tang Dynasty army is preparing to attack it in large numbers. How should we deal with it?

The two sides agreed to set up their formations and then looked for opportunities to fight.

As a result, people from Tang Dynasty flew over, specifically looking for flags to attack, and they were even giving orders.

No, we can’t let Datang have it. No, we can’t just let Datang have it. We want it too.

Whether they were fighting against the Tang Dynasty or others, the envoys from various countries were thinking about something new.

"It's better to disband all the workers. It's useless to keep them." Yao Chong went to the heaven and earth to eat. There were three of us today, but Wei Zhigu didn't come.

"Yuanzhi, don't think about it all the time." Lu Huaishen advised.

He understood how much Yao Chong was worried about and troubled by Baigong's matter.

"It's spreading all over the city. We haven't seen the real thing yet, so we should think of a way." Zhang said, turning the topic to business.

"A ball that can take people flying must have its drawbacks. Like a flying lantern, it can only move with the wind."

Lu Huaishen caught up with the topic.

Yao Chong looked at the lantern light outside: "I don't know how many people can be killed. I only know that if the wind blows towards the enemy, the enemy will definitely be on tenterhooks.

If everything is fine during the day and the wind blows at night, can the soldiers rest peacefully? Who is not afraid of being attacked in the dark? "

Yao Chong discovered that the ball's deterrent effect may be greater than its actual combat effectiveness.

"It's best not to imitate it, otherwise we would rather not manufacture it and equip the army than let the enemy learn from it."

Lu Huaishen expressed his thoughts. He was afraid that the Tibetans and Turks would use hot air balloons to cause trouble in the Tang Dynasty.

"The wind is too strong and it blows far away. Can the ball still fly back?"

Zhang Shuo frowned, he understood the Kongming Lantern and let it go.

To fly a kite, it needs to be connected with wires and the ball should be connected to the rope. How long does it need to be?

"I haven't seen anything, so I can't tell you anything. I'll ask Your Majesty to take one to the palace to see and eat."

Yao Chong found that nothing could be achieved through the discussion at the moment, so he simply didn't say anything.

Zhuangzi was eating, and the five hundred Yulin Feiqi went to fetch food. The topic of discussion was hot air balloons.

"When I went up today, at a height of twenty feet, the wind was blowing eastward. When it reached thirty feet, it was blowing southeast, and when it was fifty feet, it was blowing westward."

"I also discovered it, but the wind blew north when I was ten feet away, and northwest when I was fifty feet away."

"Is it true that the greater the height difference, the more obvious the change in the direction of the wind blowing?"

"Let's see tomorrow and fly higher. If that's the case, wouldn't it be possible to change the direction if we adjust the altitude?"

The Yulin Flying Riders discovered the secret in the chat, as long as they mastered the altitude and wind direction.

A hot air balloon without a rope can fly back again after it flies out.

Get to the enemy's head, fly over it, choose a height, and turn back. The process will be slower, but you can still cause damage to the enemy.

When the wind is too strong, it will not fly.

Li Yi, who was eating in a private room, talked about his new idea.

"Make a batch of Kongming lanterns, make them a little bigger, put the burning oil in them, then light the incense and put them on the ropes stretched inside the brackets.

When the incense burns there, the rope is burned, the lamp or candle tilts, ignites the oil, and the fire burns away the paper.

Burning cans of fiery oil fell from the sky, setting fire to the enemy camp below.

Many sky lanterns will fly sideways and far away, which is a waste of things.

But in a battle, if you succeed at the critical moment, the enemy camp will be in chaos. "

Li Yi said a new method that he had figured out. The two sides fought and succeeded only once.

"No, if the enemy sees it, the enemy will follow suit. Tubo always likes to sneak attack on us, Datang."

When Li Chengqi heard this, he had a good idea. A large number of Kongming lanterns were released in the wind, and if some of them fell down, it would be considered a success.

Nowadays, no one has to use it, no one thinks of reminding the enemy, and the enemy gathers the Kongming Lantern for an attack.

When the wind direction is right, they are released to burn Datang's military rations and other items. Datang's losses are more than the cost of making Kongming Lanterns.

Li Longji nodded: "Yes, don't say it, so as not to spread it."

"Ah!" Li Yi thought about it, and it made sense. He didn't know how much money the Turks had. Tubo had craftsmen, fields, and oil there.

If Tubo wants to make it, it is guaranteed to be made.

Nothing happened that night, and the next day, Zhuangzi's craftsmen made two more hot air balloons.

Yulin Feiqiu continued to go up and test the flight. The length of the rope was controlled at 200 feet. At most, the rope could be used up.

This time, more people came to watch after hearing the news. They could not enter Zhuangzi, so they watched outside Bashui.

The hot air balloon is big enough to be seen rising.

Including envoys from various countries, seeing three balls going up and down today, sadness welled up in their hearts and was written on their faces.

When the people of the Tang Dynasty saw it, they cheered as if tomorrow the Tang Dynasty would wipe out all the surrounding forces.

Li Longji finished his morning court, and Yao Chong and the other three refused to leave.

"Your Majesty, I have heard rumors that there is a new thing in Lijiazhuangzi. It is in the shape of a ball. There is a basket under the ball, and there are people in the basket. I don't know..."

Yao Chong asked directly.

Before he could finish speaking, Li Longji nodded lightly: "Yes, hot air balloon, Yu Lin Feiqi is training. In the future, we will look for suitable weather and opportunities on the battlefield to attack the enemy."

"Is this thing easy to make?" Lu Huaishen was worried.

"It's easy to make. Lijiazhuangzi is easy to make. The alcohol used can't be made by others, and the alcohol blowtorch can't make it either." Li Longji understood what the old minister was thinking.

Zhang said, "How much will it cost?"

"I will pay for it, so you don't have to worry."

Li Longji did not mention the cost, and he did not want the state treasury to provide funds. Zuo Zang took the money, and the court had to supervise it.

Is Li Yi's Zhuangzi a place that others can control? And the cost is divided into material cost and technology cost.

The materials are not expensive, and the technology was something Li Yi finally figured out.

Oh, just pretend it’s not easy.

"Your Majesty, we want to take a look." Yao Chong was helpless when he heard that Li Longji would not pay the court's account.

The previous gunpowder was not under the control of the imperial court, it was such a dangerous thing.

Today's hot air balloons are not under the control of the imperial court. The hot air balloons are added with gunpowder and floated from Zhuangzi to the imperial city...

"Tomorrow morning, I will send Yu Lin Feiqiu to bring one over." Li Longji agreed and let you see it.
