Da Qin: At the age of six, I beat Qin Shihuang at the beginning

Chapter 323 Take Off
Zulong was in the hanging basket, frowning slightly.Now this feeling is not good.In the hanging basket, the space is not too big, Qin Mu piled up a lot of coal powder to ensure battery life.Not far behind Zulong was the flames produced by burning coal powder. Such a short distance... made Zulong instinctively unwilling to approach, but the hanging basket prevented him from moving further.

"The son of a thousand gold can't sit down", let alone an emperor who is ninety-five years old?With this brazier so close, what if the brazier is blown over by a strong wind?Oh... don't worry, Mu'er is right next to him. With his medical skills, as long as he is still alive, there will be no problem... But, what is this for?
These braziers are so hot after burning... Could it be some kind of heating equipment?Xianyang is still very cold in winter.In the past, if Zulong was cold, he basically used a hand warmer and stuffed some lit charcoal into it.The stove has a two-layer structure with water insulated in the middle, so it won't be hot.

However, setting up such a big brazier is a bit too much, right?Not to mention heating, this thing is enough for cooking!Besides, the flames are so big, I'm afraid everyone in this hanging basket is not cold!By the way, it's very cold outside the Great Wall. Could it be that Qin Mu made this thing to protect the soldiers from the cold?
Zulong's eyes lit up, it must be like this!Qin Mu's thought was too thoughtful!However, he still doesn't quite understand what the big balloon above is for.It would be an exaggeration to say that it is for shelter from the wind and rain, but an umbrella can solve it!
Zu Long was thinking wildly, but heard Qin Mu whisper: "Father, hold on tight!"

Zu Long froze, subconsciously grasped the handrail of the hanging basket in front of him.Although I don't know why Qin Mu suddenly let him catch him, but after such a long time, Qin Mu has already proved himself.At least, in the few times that Zu Long personally witnessed, Qin Mu never made a mistake.

In the next moment, Zu Long only felt the hanging basket under him shake slightly, and then began to shake.

"Mu'er, what's going on? Why is this hanging basket... kept shaking?" Zu Long grabbed the handrail and turned to ask Qin Mu.In fact, it doesn't matter if it shakes a bit, but the hanging basket was originally fine, but now it shakes, it can't be broken, right?

Qin Mu smiled, and approached Zulong's position: "Father, look at your feet!"

Hearing this, Zulong lowered his head and looked down, his pupils shrank suddenly!He couldn't believe his eyes, the hanging basket that was originally placed on the ground has gradually left the ground at this moment!Zu Long glanced over, and now the hanging basket is not too far from the ground, only about an inch or two, but he can be sure that this hanging basket is still rising!

Zulong raised his head suddenly, the hanging basket would definitely not rise for no reason, since it was originally on the ground, but now it is off the ground, then...someone must be pulling it up!But...he looked up, and there was only a huge balloon, and there was no one on it!This balloon is extremely empty, with a huge interior space, but it can be seen at a glance!
"There's no one up there, so how could it be off the ground?" Zu Long looked at Qin Mu, his eyes were so unbelievable that he couldn't hide it: "What is this hot air balloon for? Could it be..."

Qin Mu nodded: "That's right, this hot air balloon is what Feitian uses!"

Flying use!Zu Long got the answer he guessed, but this answer made him a little dizzy!Fly!The dream of many generations!From the beginning of writing in Huaxia, we can see countless people's dedication to Feitian!Far away, there are those who jumped down from the mountain with kites on their backs, and there are also literati who imagined flying into the sky in their poems. Even the common people have dreams of flying into the sky. Although they are not themselves, they regard those immortals as existences that can fly into the sky .

Why is Liezi the most famous immortal since the pre-Qin period?Isn't it because many schools of thought have recorded that they saw Liezi walking against the wind with their own eyes?
Now, Qin Mu can actually fly into the sky... Doesn't it mean that Qin Mu is an immortal?No... Qin Mu is more powerful than an immortal, after all Lie Zi can only fly by himself, but Qin Mu can fly with him...

Zu Long's thoughts were a little confused. In his mind, he thought of legends, literature, the flying sky he had longed for when he was a child, and the immortals described by alchemists... In fact, the hot air balloon Qin Mu gave The impact he brought was far more than that!

"Mu'er... How high can this hot air balloon fly?" Zu Long was in a daze at the moment, the hot air balloon had risen more than ten meters high.Looking down, the visual impact is already very strong.The original high-walled compound now looks like a sandcastle built by a child.

Qin Mu thought for a while and gave a number: "The time is too short, and the balloon is a little rough, so it can only rise to more than 30 feet! If it is improved in the future, flying to the sky of hundreds of feet will not count Very difficult."

What Qin Mu said was the truth.After all, Daqin had limited conditions, and he was very anxious, so he could only use some to survive.For example, the fabric he used, although strong, was too heavy.Including the sheepskin used, in fact, animal fur is not a particularly good material because it is too thick, but at this time, it is difficult for Qin Mu to find any high-strength materials.

Even, if he didn't know something about tanning fur, even these sheepskins might not be usable!There is also the problem of fuel. Coal mining is simple, but the heat release efficiency is still too low. In order to increase battery life, you can only carry a large amount of coal powder, and...the other half must be used for the return trip, otherwise the hot air balloon will run out of fuel... It's not fun to fall off.

As a result, this hot air balloon is actually not efficient and heavy, so naturally it cannot fly very high.Even during the production process, Qin Mu had the urge to look for oil fields more than once, wanting to start the petrochemical industry and solve the problem of materials and fuel at once.

Of course, thinking about the time, Qin Mu still bit the bullet and accepted the current situation.

However, even if it is only more than 30 feet, it is enough to shock Zulong.Thirty feet!It doesn't look high on the ground, but in fact, it's as high as ten floors!

Looking at the ground from this height, even some small things are invisible!
"With this, wouldn't it be possible to fly into the sky?" Zu Long's excited lips were trembling: "Mu'er, this...you brought it back from the fairy world?"
