Everyone looked at Hua Xiong again.

"Lord, can this cloth really go to heaven?"

Gao Shun asked with a skeptical expression.

"Nonsense, of course you can."

Hua Xiong smiled,

"But just by relying on the fabric, I want to go to heaven.

That's not possible, of course.

Ding Gong, you should also study the rest of the parts and settings. ”

"Yes, my lord!"

Ding Shuai nodded in response.

"My lord, if this is to be studied, how much will it cost?"

Gao Shun asked tentatively.

The fabric alone cost 100 million dollars, so wouldn't it cost even more to successfully study it thoroughly?

Hua Xiong touched his chin and thought for a moment, "I estimate that three or five billion dollars is about the same." ”

As soon as these words came out, everyone couldn't help but smack their tongues.

Spending three or five billion dollars, if you can research success, it will be fine.

If the research fails, won't it be a waste?

"You can rest assured, when the research is successful, I will naturally take you to heaven together."

Hua Xiong laughed.

……

Nothing was said all night.

Early the next morning, Hua Xiong got up and went straight to the Ordnance Division to find Ding Shuai, who was busy.

"How's the device ready?"

Hua Xiong asked.

"My lord."

Ding Shuai saluted Hua Xiong,

"Except for the fabric, everything else is easy to prepare.

But what is uncertain now is how much weight this thing called a hot air balloon can bear. ”

"Well, we can try a few more times to minimize the danger."

Hua Xiong admonished.

"Yes, my lord!"

Ding Shuai took the order and left.

After a while, he took several apprentices with him and carried all the parts prepared for the realization to the courtyard.

While the apprentice was assembling the hot air balloon, Ding Shuai walked over and couldn't help asking,

"Lord, why are you so sure that this thing can fly?"

Hua Xiong smiled faintly and asked rhetorically, "Do you know Kong Ming lanterns?" ”

"I don't know."

Ding Shuai shook his head honestly.

Hua Xiong patted his head, and then remembered that Kong Ming's lantern was a successful invention by Zhuge Liang.

Zhuge Liang still doesn't know, whether he has defected to Liu Bei.

He groaned slightly, pulled a few pieces of tissue paper, and brought a few pieces of bamboo.

It didn't take long for a simple Kong Ming lantern to be made.

There was a heavy snowfall last night, and today the weather is clear, cloudless, and there is not a single wind.

Hua Xiong came to the middle of the courtyard and lit the small candle placed in the Kong Ming lantern.

He gently placed the Kong Ming lantern on the ground.

After a while, Kong Ming's lantern flew up lightly.

Seeing this scene, Ding Shuai looked horrified, and his mouth opened widely.

"Lord...... Host...... Gong, you ...... How did you do it? ”

If he hadn't seen it with his own eyes, Ding Shuai would have found it hard to believe his eyes.

"Actually, it's very simple."

Hua Xiong pointed to the materials on the side and explained,

"This is because hot air is lighter than cold air.

The burning of candles causes the air inside to expand by heat and become less dense.

Generate upward lift to fly.

Do you understand? ”

Ding Shuai shook his head in confusion, "I don't understand." ”

Yes, it is equivalent to explaining in vain.

If you want Ding Shuai to figure it out, you probably have to teach him junior high school physics.

Hua Xiong didn't bother to explain so much.

He just waved his hand,

"If you don't understand, forget it.

All you need to know is that hot air balloons work in much the same way as sky lanterns.

As long as you can make a hot air balloon according to my request, then let's ride it to the sky! ”

As soon as these words came out, Ding Shuai's eyes suddenly lit up.

From ancient times to the present, no one has ever been able to ascend to the sky!

If I could make something like this, I would definitely be able to make a name for myself.

"I see, my lord!"

Ding Shuai nodded again and again.

"It's good to understand, let's go."

Ding Shuai turned around and threw himself into the work with great energy.

An hour later, Ding Shuai ran over again in a hurry.

"Lord, the hot air balloon has been successfully studied!"

Hua Xiong followed him into the courtyard.

I saw the hot air balloon lying there quietly.

The body of the ball is made of materials such as silk and paulownia paint, and a large hanging basket is attached underneath.

"Light tung oil."

Hua Xiong commanded.

Ding Shuai took the order and left, and soon the fuel in the gondola began to burn.

Everyone present looked at this big guy with nervous eyes.

After a while, the hot air balloon is filled with hot air and slowly begins to inflate.

"Get up! Get up! ”

I don't know who screamed first.

Everyone looked closely, but no, the hot air balloon began to float into the sky.

The hanging basket at the bottom also left the ground.

If it weren't for the ropes, I'm afraid I would have to fly into the sky directly.

"Lord, we have succeeded in researching!"

Ding Shuai looked at Hua Xiong excitedly, almost not jumping up.

Hua Xiong bowed slightly, smiling, and a big stone in his heart also fell to the ground.

Although he had made Kong Ming lanterns before, it was the first time he had ever seen a hot air balloon.

If it fails, hundreds of millions of dollars will be wasted.

Fortunately, God willing, this hot air balloon research has been successful!

"Lord, do we want to go up and have a look?"

Ding Shuai asked expectantly.

Hua Xiong groaned slightly, "Okay, let's go up and have a look together." ”

Considering the carrying capacity of the hot air balloon, Hua Xiong only took Ding Shuai to the hanging basket.

The two of them increased the speed of the burning, and asked the apprentices below to slowly loosen the rope.

After a while, in the shocked eyes of everyone, the hot air balloon slowly floated into the sky.

As they farther and farther from the ground, the apprentices of the Ordnance Division gradually lost sight.

And the miniature version of Luoyang City caught Hua Xiong's eyes.

Although he had taken a plane many times in his previous life, in ancient times, it was the first time he had flown so high.

Feeling the cold air and the biting cold wind, Hua Xiong couldn't help but feel relaxed.

But Ding Shuai on the side was not in such a good mood.

It was the first time he had come to such a high place.

Looking at the small Luoyang City under his feet, Ding Shuai's face turned pale with fright.

He involuntarily held the hanging basket.

"Relax, Dinggong, it'll be fine."

Hua Xiong comforted in a good voice.

Affected by his calm attitude, Ding Shuai calmed down after a while.

He stretched out his head, looked at the empty sky around him, and couldn't help but ask,

"Lord, didn't you say that the immortals all live in the sky, why didn't you see them?"

Hua Xiong smiled dumbly.

"Who told you that the gods live in the sky?"

"That's what the myths say."

"Myths are all lies, how can there be any gods and ghosts in this world?"

Ding Shuai touched his head and stopped talking.

Seeing that the scenery was almost over, Hua Xiong carefully adjusted the temperature of the fuel and controlled the slow descent of the hot air balloon.

Following the rope that had been tied in advance, the hot air balloon that the two had ridden fell back to the Ordnance Division again.

With his feet on the ground again, Ding Shuai breathed a long sigh of relief and looked at Hua Xiong with admiration.

"Lord, I Ding has met a lot of capable people, but the lord is definitely the one I admire the most."
