More than half a month has passed soon.

The Yuan army in Wuzhou City is still resting and there is no movement.

The layout of the Song army has been completely improved, and the post stations in the middle of the army and division headquarters have been built.

Wen Tianxiang and Zhang Jue's command centers are stationed at the border between Tengzhou and Rongzhou, and coordinate the overall situation of the guerrilla forces.

At this time, Zhao and Luo finally led the Yongzi Army and Gangzi Army under the Qiongzhou Army to Cenxi.

At the same time as him, Liu Hongyi's grain transport troops were also here.

However, these were not the things that made Zhao Dongting most happy, and the things that made him most happy, were the craftsmen of the military industry who came with the grain transport troops.

They finally made the hot air balloon and brought several samples.

Zhao Dongting met these craftsmen of the Military Industry Department at the government office. He was surprised to see that the hot air balloons they made were basically the same as the picture albums he drew. Then he went outside and saw the craftsmen of the Military Industry Department performing hot air balloons to ascend to the sky for him and changing directions, which surprised him very much.

He has long been looking forward to the hot air balloon.

When several craftsmen fell from the air, he asked repeatedly: "How many hot air balloons have been created in the Military Industry Department now?"

However, the craftsman in the lead was a little embarrassed and replied: "Report to the emperor, now... he has only created this one."

Zhao Dongting was stunned and frowned, "How could this be?"

The craftsman said bitterly: "This hot air balloon has extremely high requirements for cloth. People from the Military Department have finally developed this cloth these days. However, from spinning, to weaving, and soaking in the cloth, it takes several girls with excellent weaving skills to work hard for more than ten days. Moreover, if you are not careful when soaking in the oil, the cloth will be breathable. The emperor of the court has asked the dyeing workshops in Leizhou to speed up the production, but the progress is still slow."

"this……"

Zhao Dongting's excitement just now was like being poured on cold water, and it was extinguished a lot in an instant.

He originally thought that if there were tens of thousands of hot air balloons, tens of thousands of soldiers flew over Wuzhou at the same time, they would definitely blow up the entire Wuzhou city to flat ground. But now it seems that this is obviously impossible.

With the current national strength of the Song Dynasty, it was impossible to make too many such hot air balloons, and it would take a long time.

He frowned and said, "Then you go back with my oral orders, let Li Qingyun leave the rest of his work and speed up the production of this hot air balloon."

The craftsmen were surprised and whispered: "Your Majesty, the dragon gun and the thunder chariot..."

Zhao Dongting waved his hand, "I don't lack the Shenlong gun and the thunder cart now, what I lack is this hot air balloon."

The craftsmen stopped talking and quickly took the order.

What the emperor was thinking in his heart, they didn't dare to think too much. Anyway, the emperor's order was just implemented.

After the craftsmen left, Zhao Dongting came to Zhao Da and Zhao Hu.

Zhao Da and Zhao Hu came over with doubts and asked Zhao Dongting, "Emperor, what's wrong?"

After they became the chief and deputy commander of the Feilong Army, they were also very busy and always had to train Feilong soldiers during the day.

Compared with ordinary soldiers, the training tasks of the flying dragon soldiers treated as special forces are undoubtedly much greater.

Zhao Dongting pointed to the hot air balloon in the square and said, "I will let you two try my newly invented hot air balloon."

Zhao Da and Zhao Hu's eyes suddenly lit up, and they hurriedly ran towards the hot air balloon like a curious baby.

There were thunder, grenade launchers, dragon guns, etc., and now they heard that Zhao Dongting had a new invention, they couldn't help but feel excited.

Which of the emperor's inventions is not a big killer weapon?

However, when they ran to the hot air balloon, the two looked left and right, but were stunned.

Zhao Da blinked his eyes and asked, "Emperor, how can this thing kill the enemy?"

Le Wuchen couldn't help laughing next to Zhao Dongting.

When he saw the hot air balloon just now, he also had such doubts as Zhao Da. It was not until he saw the craftsmen flying with hot air balloons that he suddenly realized the function of the hot air balloon.

Thinking of this, he couldn't help but turn his head to look at Zhao Dongting next to him.

It was hard for him to imagine how the emperor had such a big brain. He was the same person.

He is not a skilled craftsman, but for thousands of years, he has never heard of any great craftsman who has made such a flying thing!

This is a real flying sky, unlike a master in the martial arts world who briefly leaped on high places with superb light skills.

Zhao Dongting walked to Zhao Da with a smile, stepped into the hanging basket of the hot air balloon and said, "You two come in first."

Zhao Da and Zhao Hu hurriedly stepped in, then touched the left and then touched it again.

Zhao Dongting slapped the two of them, "Don't touch them randomly."

Then he explained to the two in detail how to operate the hot air balloon.

After hearing this, the two brothers' eyes emitted light, and Zhao Dazhi shouted, "How can this thing really fly? Master, let's try it quickly, try it quickly."

The two of them have been following Zhao Dongting for a long time. Now there are no outsiders, so naturally they are no longer as reserved as before.

Zhao Dongting nodded with a smile, "Okay, Zhao Da, you can light the fire. Zhao Hu, you and I will operate this hot air balloon together."

Both brothers couldn't wait, and Zhao Da wanted to light the fire when he heard this.

Le Wufeng looked around and shouted repeatedly: "Master, are you going to try it out in person?"

Although he had just watched the craftsmen perform with his own eyes, he was still a little worried at this time, afraid that something would happen.

If a hot air balloon suddenly has problems and falls down in the sky, no matter how skilled a person is, he will have to fall into a paste, right?

Zhao Dongting knew that Le Wuxuan was worried about him, so he said, "Senior, don't worry, I'll try it in a low altitude."

If it is a few meters high, with Zhao Dongting's current skills, he will still be unable to die.

"Your Majesty, don't fly too high!"

Le Wuchen still couldn't help but remind him again.

Now, in his eyes, Zhao Dongting is not only the emperor, but also his son-in-law, the sweetheart of his eldest daughter.

Whether it is public or private, happy or free, he will never want to see Zhao Dongting have any accidents.

Zhao Dongting and Zhao Hu raised the canvas of hot air balloons.

Zhao Da lit up and got angry.

As the flames gradually rose, the canvas of the hot air balloon gradually swelled.

Then, as Le Wuchen and the witness of a few soldiers around him, the hot air balloon ascended to heaven again.

The soldiers were amazed as if they saw miracles.

Zhao Dongting can be said to have created the history of flying in this era.

Zhao Da and Zhao Hu were so excited that they kept grinning and laughing.

Zhao Dongting suddenly felt a little moved as he watched his feet get farther and farther away from the ground.

This is ancient times, this is the country.
