Throne of Vientiane Civilization

According to the situation in Xianyang City, if they delay any longer, the opponent will basically be defeated. This is undoubtedly the most trouble-free and labor-saving situation for them.

"Let Xie Liancheng and Zhou Chongshan prepare. If I fail to come back, let them take over Feiyan City in half a month."

Riding on horseback is definitely faster than the previous large army with infantry. From Xianyang City to Green Forest City, Zhou Xu and Silke rode their own horses. It only took three days, but it took four or five more to get to Green Forest City. It only takes 3 days, and the single trip is almost a week, and this is without any delays on the road.

According to this algorithm, it would take almost half a month just to go back and forth, not to mention that he would have to stay in Black Rock City for a while to study new projects with Zhuang Mengdie.

Half a month's time, 100% impossible to come back.

As for the situation in Feiyan City at that time, he didn't know whether Long Aotian exaggerated in his message.

But it doesn't matter, according to their strength, even if Feiyan City still has the strength to fight, they can directly blow it up, which is just a matter of two extra efforts.

Or just observe from the outside and don't get close.

Even if Long Aotian exaggerated in his letter, Zhou Xu estimated that it was too much.

At the same time, after a winter, it is normal for the city's food reserves to bottom out. It will only take another ten days and a half at most to wait for a result.

After arranging things here, the group continued on their way. After arriving at Green Forest City, they rested for a day.

When there was no time to rush back, Zhou Xu wasn't so anxious anymore.

After all, even if they don't need to rest, this war horse also needs to rest. After three days of high-intensity driving, if he continues to run, he will probably foam at the mouth.

Within their Great Zhou Dynasty, these carefully selected war horses are quite expensive, and their number is relatively limited. When they are not fighting, they must be taken care of.

On this trip, they spent a total of nine days on horseback and successfully arrived at Black Rock City.

After arriving at the place, Zhou Xu didn't even take a break. He called Zhuang Mengdie directly and chatted with her about the new design.

Along the way, he had already clarified his ideas and drew a rough design drawing. After his explanation, Zhuang Mengdie quickly had a rough understanding of the structure of this new project. .

However, she still couldn't figure out what this thing was used for.

"Don't worry, let's make a super simplified version first to practice. Once this super simplified version is made, you will roughly understand what this thing is used for."

When Zhou Xu and the others arrived at Blackstone City, it was already approaching evening. By the time he and Zhuang Mengdie finished talking about their ideas and briefly describing the principle and structure of this thing, it was basically dinner time.

After dinner, the two lit up the brazier and started cooking what Zhou Xu said was a super simplified version.

This super simplified version is indeed simple. Zhuang Mengdie can make every part, and it is not complicated. Coupled with her skillful hands, the two of them worked together to create something from scratch, and it took less than an hour. In a matter of seconds, I made this thing.

"Come on, let's find an open place."

While talking, Zhou Xu motioned to Hilke and the others to get their things and moved Zhuang Mengdie to an open place.

"Silk, you are holding on."

While signaling Hilke to stabilize the thing, Zhou Xu did not hesitate, held up the torch in his hand, and lit the brazier fixed at the bottom quite neatly.

Soon, the fire ignited in the brazier, and as the internal temperature increased, the hot air was generated, causing the cover as the main part to slowly bulge.

Gradually, Hilke could feel that the things in his hands were about to escape.

"Your Majesty, what should we do now?"

"Let go, just let go of your hand."

Following Zhou Xu's words, Silk let go of his hand. At that moment, the thing in front of him slowly rose into the sky in front of everyone present.

This scene made everyone except Zhou Xu couldn't help but exclaim.

"See, this is the sky lantern!"

Zhou Xu, who said this, raised his head proudly, with a look of nostalgia on his face.

When he was a child, he and his grandmother would make a lot of money by selling sky lanterns during festivals. Of course, later on, the country stopped selling lanterns and the business disappeared.

Looking up at the sky lantern flying higher and higher, Zhuang Mengdie's eyes burst out with bursts of brilliance.

During this period, the nearby people in the city who did not know the truth, after seeing the flying sky lanterns, knelt down in large areas on the street and worshiped in the direction of the sky lanterns. Each one of them thought it was a god. spirit.

The sky lantern flew further and further away, but under the cover of night, the group of light and shadow was still conspicuous.

Everyone kept their heads raised until the lights completely disappeared from their sight, and then they looked back.

Sky lanterns have existed since ancient times. During the Three Kingdoms period, they were also called Kongming lanterns. They also had certain military value and could be released at night as military signals.

"Mengdie, do you understand now what I want to create?"

Hearing this, combined with the design drawings he had seen before and some additional instructions from their king, Zhuang Mengdie, who had now reacted, nodded vigorously, with uncontrollable excitement on his face.

"I will use better materials to make a lampshade, and the bottom will be replaced with a more spacious basket. People can sit in it and fly to the sky!"

Listening to Zhou Xu's description, Zhuang Mengdie and Silke's faces showed longing.

Flying into the sky was not something everyone could do, even in the old civilization when gods appeared.

"When it reaches this point, it can no longer be called a sky lantern, but a hot air balloon!"

Needless to say, this is what Zhou Xu wants to do!

As long as they have hot air balloons, they can fly over the mountainous areas regardless of the terrain. In this way, their movement efficiency can be greatly improved!

Of course, the carrying capacity of hot air balloons is very limited. From the beginning, Zhou Xu did not expect to use it to transport goods or troops. It was just used to transport some important people and objects.

For example, he wanted to go back to Black Moon City. If a hot air balloon took him over the mountainous area, it would save a lot of time.

In addition, it can be put into military use in the future. Not to mention anything else, it should be very useful as an aerial reconnaissance unit.

As for the difficulty of production...

To put it simply, a hot air balloon is a super-enlarged version of a sky lantern. They had even successfully launched one just now.

But considering its use, its stability and safety are very important, and Zhuang Mengdie needs to study it carefully and conduct a lot of tests at the same time.
