"I wonder if you know about Kong Ming Lantern?" Liu Renyu knew that the generals of the Liao army definitely didn't know what a hot air balloon was, so he would first say something that everyone knew in order to make an extension.

"Nature knows, Kong Ming lantern, covered with paper, inside to hold fire, can fly into the sky." Zukefa was young and clever, and immediately answered.

"What General Zu said is very true, the hot air balloon that the last general said is a super-large Kong Ming lantern, which can not only fly into the air, but also fly with people." Liu Renyu said with a smile.

"The large Kong Ming lantern can still fly with people!?"

This kind of thing has exceeded the limit of the cognitive level of the generals of the Liao army, so they have been blinded again.

Liu Renyu had already expected that the generals of the Liao army would not understand the novelty of hot air balloons, so he decided to release the hot air balloon to open the eyes of the Liao army generals.

"The last general knows that the officials may not be able to understand what a hot air balloon is and why it can carry people, but this doesn't matter, the last general will take all the officials to see the actual object of the hot air balloon, and you will take a look at it, knowing that there is indeed such a thing in the world, which can fly up, and can fly with people. Please follow the end of the world. ”

After Liu Renyu said this, he should take the first step and go straight to his barracks.

Driven by strong curiosity, the generals of the Liao army hurriedly followed behind Liu Renyu and walked towards the Jingbianbao military camp together.

"Jiye, the generals of the Liao army are here, and ask our air force to assemble the hot air balloon and show it to them." Liu Renyu pointed to the Liao army generals behind him who did not know the truth, and said to Li Jiye with a slight smugness.

"Yes, General." When Li Jiye received the order, he made a detour around the barracks for a while, bringing more than a dozen soldiers and three carriages wrapped in thick tarpaulins.

"Ke Zhihong, take your subordinates to assemble the hot air balloon, and show it to the Liao army later." Li Jiye ordered Ke Zhihong, the chief officer of the Jingbian Fort Air Force, with a triumphant face.

"Yes, Master Li."

When Ke Zhihong got the order, he took a group of subordinates to lift the thick tarpaulin covering the carriage, and a thing similar to a blanket appeared in it, which seemed to be sewn from different animal skins, and the color of the fur was mixed, one in the east and one in the west, not very neat, very ugly.

Those Liao generals saw that the so-called hot air balloon was like this, and for some reason they looked down on it.

Soon, Ke Zhihong led a group of his men to take out the huge blanket made of animal fur, and then they took out a frame made of rattan in turn, and then an iron utensil, shaped like a stove, I don't know what it was used for, in addition, there was also something similar to a child's toy windmill and the like.

After Ke Zhihong picked up the hot air balloon from a carriage, several Jingbian Fort soldiers dispersed and carried the blanket made of animal fur to a high platform as high as the city wall.

At this time, the generals of the Liao army saw clearly, this blanket was a bit like a wine gourd, the mouth was open at the bottom, and the top was a little thick, but I didn't know what it was for.

Under this thick wine gourd, the Jingbian Fort army put the stove-like thing under the opening of the wine gourd, and then used a rope to connect the wine gourd with a hanging basket made of rattan.

So far, the generals of the Liao army have not had anything to do with Kong Mingdeng.

Some of the generals of the Liao army have begun to look left and right, and they are absent-minded.

Liu Renyu saw the performance of these Liao army generals in his eyes, and his face was slightly unbearable, this hot air balloon was indeed too ugly.

Now in this era there is no rubber, there is no polymer material, there is no suitable raw material that can be made into balloons, if you use paper, beautiful but beautiful, afraid of not strong, so think about it, you can only use animal skin to make balloons.

And hot air balloons are very large, and there is no such large animal skin that can be used to make a complete hot air balloon, so it can only be made with the fur of many animals.

As a result, the colors are inevitably very mixed, and the traces of needlework and sewing are obvious, which makes it look ugly.

It's all helpless, as long as things can be used, how can they be all-encompassing.

Liu Renyu comforted himself like this, then took a deep breath and said loudly to Ke Zhihong: "Mr. Ke Bai, raise the fire and rise." ”

Ke Zhihong saw that some Liao army generals saw their hot air balloons, and their eyes seemed to show contempt, and he was a little annoyed in his heart, so he thought that he would make a splash later, and let these people see the mystery of hot air balloons.

"Little ones, raise the fire, raise it, and let the officers see how powerful our air force is." Ke Zhihong ordered loudly.

"Yes, Mr. Bai." When the Jingbianbao Air Force received the order, they set the biogas stove on fire.

The flame flickered and burned, and gradually, gradually, gradually, the generals of the Liao army saw that the object shaped like a wine gourd was filling up little by little. Grow up.

At the end, the wine gourd was bulging, like a huge autumn pumpkin lying upside down.

"Let's go up for a walk, but don't let go of the rope." Ke Zhihong stepped into the hanging basket and asked his subordinates to let go.

"Yes, Mr. Bai." When the soldiers got the order, they put down the rope tied to the hanging basket, and the balloon filled with hot air slowly rose and left the ground, taking Ke Zhihong in the hanging basket into the air as well.

Dumbfounded, the generals of the Liao army were dumbfounded.

There are still such strange things in the world!

"Flying, really flying, oh my God."

Many Liao generals have already exclaimed.

Only Zu Dashou, He Kegang, Zhang Cunren, Liu Tianlu and other important generals, relying on their identities, although they are also shocked and inexplicable in their hearts, they can still force a calm look on their faces, but they are also turbulent in their hearts, so they are not shocked.

Ke Zhihong rose into the air, looked down, and found that in Dalinghe City, except for the Jingbian Fort army who had seen this thing, they were all shocked by this thing.

All the soldiers of the Liao army seemed to have been immobilized, and they could no longer move.

Ke Zhihong was very proud.

"What kind of secret weapon did the general say before, I thought it was something amazing, it turned out to be a hot air balloon!" Zhang Tieniu looked at the hot air balloon flying in mid-air, shook his shoulders, and said with a smile.

Most of the Jingbian Fort troops had seen this thing, and they were not surprised.

"Look, what's that!?" Huang Taiji, who was sitting on the hill in the south of the city, suddenly caught a glimpse of a behemoth rising in the city of Dalinghe, and for some reason he was shocked, stood upright, looked around left and right, and changed color.

"What's that!?"

The guards around Huang Taiji raised their eyes and looked into the distance, but they found that something flew up in Dalinghe City, but they didn't know what it was.

"I don't know." These guards don't know about hot air balloons, so they can only answer like this.

"What is that?" Huang Taiji knew that others must not know, but he was horrified in his heart, so he asked this question.

The unknown is the most frightening.

At this time, Huang Taiji was faintly worried in his heart for some reason.

"Why did the generals of the Ming army dare to make an appointment, is there any conspiracy, and does that thing have anything to do with this battle?"

Too many reasons lingered in Huang Taiji's heart, making him extremely uneasy.

"Call all the Baylors and ministers and let them see what is in Dalinghe City?" Huang Taiji ordered to the guards beside him.

"Zha," one of the guards received the order, and went straight to pass the order.
