On this day, Ying Tianfu was quite cold.

But Zhu Yuanzhang, who was in the inner courtyard of the palace, didn't feel it at all, he led the princes except the crown prince Zhu Biao to look up at the sky outside the main hall.

Ever since he had used Li Chenggui to help him, their monarchs and ministers had studied the topography of the high country, where there were many mountains and few plains.

Even if you send a large group of people, if you are not familiar with the terrain, you will suffer a loss there.

So, yesterday he spent a day preparing a court meeting to discuss this issue, Lu Ning said.

"If Your Majesty wants to break this situation, the minister has a way."

"Then tell me about it."

"Actually, we can take some airships."

"What is an airship?"

"It's a tool that can fly people up and fly over the enemy to drop bombs, and I'm in the process of making it."

At this moment, the monarchs and ministers of the Ming Dynasty were completely stunned, no one thought that there was such a wonderful weapon in the world.

Zhu Yuanzhang also felt very novel, so he asked how to make that thing.

At this time, two guys with iron heads suddenly appeared, and they knelt down after work.

"Your Majesty, Lu Ning's demonic words confuse the public, he is following Wang Mang's old path, don't believe it!"

Hearing the opposition, Zhu Yuanzhang was stunned for a moment.

The previous Huo Biao and Lu Ning worked against each other, but after being slapped in the face madly, he was sent to Hamiwei to ask him to plant cantaloupe.

Why is there another guy with a head in the iron who came forward to find trouble today? If you look closely, it turns out to be someone from Qin Tianjian.

The older man's name was Liu Fei, who was the supervisor of Qin Tianjian, and the slightly younger one was his deputy, named Guan Youli.

This Qin Tianjian not only has to calculate the legislation, but also has the obligation to persuade the emperor's words and deeds according to the rules of the heavens, which is equivalent to half of the imperial history.

Zhu Yuanzhang was a little unhappy and asked him.

"How is this what Wang Mang is doing? You have to explain it to us, otherwise you will be slandered, and you will be held responsible. ”

After listening to Zhu Yuanzhang's question, Liu Fei said.

"There was a man who told Wang Mang that he could make himself fly, so he tied a wing to his body and jumped off the cliff, but fell to his death."

Those who read the Book of the Later Han Dynasty all knew this history, and couldn't help but sigh, and said in their hearts, Lu Ning, you are still floating.

At this time, Guan Youli also spoke.

"When the Duke of Fu Guo said this, he scolded His Majesty for being a faint monarch like Wang Mang, his heart can be punished, and his crime deserves death!"

Zhu Yuanzhang was angry and wanted to get angry, but Lu Ning told him.

"Your Majesty, think about it carefully, which of those suggestions made by the minister has not been realized? At this time and that time, Wang Mang had little grasp of the principles of heaven and earth at that time, so he couldn't fly, and I couldn't fly even if I knew it. ”

Zhu Yuanzhang thought for a while, and then said to Lu Ning.

"It's okay, let's give you a few days, as long as you fly, I will have a heavy reward when I come back, if you can't fly, I will settle accounts with you."

Lu Ning smiled and said.

"Your Majesty, if I can't fly, I will naturally admit punishment, but if I can, what should I do with these two boys who pick bones in eggs?"

Zhu Yuanzhang immediately clapped his hand and said.

"If you can really fly, the matter of calculating the Ming calendar will also be left to you. I feel that the Great Unification Calendar is still a little insufficient, after all, when Guo Shoujing began to calculate, it has been more than a hundred years since now. ”

After Lu Ning's intense Zhang Luo, there was a later flight test.

At this time, Lu Ning was on the top of the Purple Mountain, and with him was the crown prince Zhu Biao.

I saw Lu Ning take out a huge sphere woven with upwind canvas, and there was a keel made of bamboo strips on the outside.

Underneath this sphere is a basket for fuel, in which are placed a lot of fine coal.

As several soldiers blew the air with the sealed box, countless hot air was washed into the hot air balloon.

The balloon became lighter and lighter, and gradually floated upward, at this time Lu Ning said to Zhu Biao.

"Prince, do you really want to accompany me into this airship glider?"

The prince seems to be weak, but his bones are full of Zhu Yuanzhang's blood, and he said without hesitation.

"No matter how dangerous it is, is it dangerous to have a father to fight in the north and south on the battlefield? My father is not afraid, and neither am I! ”

Lu Ning led the prince into the hanging basket and began to instruct the soldiers to increase the fuel.

The balloon flew up from the top of the Purple Mountain, and the people below looked down like ants.

As for the rudder that he adjusts the direction, it is a few bellows placed outside the gondola, and as long as the direction of the jet is adjusted, the direction of the balloon's flight can be changed.

Under Lu Ning's control, the balloon flew smoothly over Ying Tianfu, and then appeared above the Imperial Palace.

Lu Ning ordered to reduce the fuel, and the hot air balloon landed slowly, and after a few circles, it landed steadily beside Zhu Yuanzhang Junchen.

The prince and Lu Ning got down from the hanging basket together and kowtowed to Zhu Yuanzhang.

At this time, Liu Fei and Guan Youli of Qin Tianjian were completely stunned, their eyes rolled, and they buttoned Lu Ning with a hat.

"Your Majesty, this Lu Ning is so bold that he dares to fly to your majesty's head, this is to rebel, and he is extremely rude to his father, and he must not be spared!"

Zhu Yuanzhang is a Ming Jun of eternity, who doesn't know that these villains hurt Lu Ning in bad words. He was so angry that he scolded.

"You two bastards, you can't do serious things, but you're just slandering right there! According to you, the birds and the white clouds in the sky are all about to create a rebellion? Drag it down and hit the forty boards again, and then cut down for the people! ”

Out of jealousy, these two guys wanted to shoot Lu Ning's black bricks, but they met Zhu Yuanzhang.

Instead, the black brick landed on his head and was smashed to the ground, which was also a huge deterrent to other opponents.
