Bang! A loud bang was heard. ∽↗∽↗，

I saw that the hot air balloon was hit by the big stone in the basket below and fell so heavily on the open space of the barracks and schoolyard, directly smashing the ground into a huge crater and splashing up bursts of dust.

Everyone looked at the big pit with sweat, and the cold sweat on their foreheads inadvertently flowed down like that, if it wasn't for Zhou Fan pulling them to run fast just now, those stones would probably have to fall on their heads, they didn't think that their heads were as hard as the ground, and then it would definitely be the end of their heads breaking and bleeding to death.

And fortunately, Zhou Fan moved the experimental place to the open space of the military camp and school, if it is still in that small courtyard, once the hot air balloon falls like that, it is better to smash his Zhou Fan's state pastor mansion out of a big pit, in case of a coincidence, drifting a little farther away, smashing other people's houses, or hitting someone, it will be bad, such a big movement, even if Zhou Fan wants to hide it, there is no way.

Zhou Fan looked at the big pit with palpitations, and was even more glad in his heart, fortunately, he was careful and didn't directly let Xiao Qiao, the little girl, go crazy directly, otherwise now this little girl is afraid that she will be damaged, she doesn't have the wings of the golden eagle and the silver eagle.

"See, it's good that I didn't let this girl go up, otherwise how would you let me explain to Uncle Qiao." Zhou Fan patted it.

Xiao Qiao's mouth flattened, obviously a little dissatisfied, and muttered in a low voice: "It's not that Brother Yuanyang, you don't have the ability to make such a dangerous thing." ”

Brushing and brushing, in an instant, all the small eyes stared at Zhou Fan, their eyes full of doubt and distrust. Previously, he Zhou Fan also said that he had the ability to make people fly in the sky, but now it seems that he is obviously bragging.

Rao is Zhou Fan is thick-skinned, and he was a little embarrassed to be stared at like this by so many innocent eyes, and hurriedly quibbled: "This is an accident, an accident." Didn't it fly just now, as long as it was slightly improved, it wouldn't be dangerous. ”

However, at this moment, Zhou Fan also muttered in his heart, he didn't know what was wrong with this hot air balloon, it was obviously the same production process as the Kong Ming lantern, why did the small Kong Ming lantern fly so high, this big hot air balloon flew out less than a hundred zhang, and it was so wasted, it was really depressing.

The words were still looking at Zhou Fan with suspicious eyes. Zhou Fan was embarrassed for a while, and he couldn't get off the stage.

"Big brother, why don't you ask Mr. Ma to help." Looking at Zhou Fan's appearance of not coming to the stage, Zhou Ning walked over and said.

"That's right, Deheng!" Zhou Fan said suddenly, and glanced at Zhou Ning with some gratitude, sure enough, she was still her own daughter-in-law, not only helping herself to solve the siege. I also helped myself think of such a good way, and now I shouldn't have to be discredited in front of these little ghosts.

There is a specialization in the art industry, and Zhou Fan will only make that kind of Kong Ming lantern toy, and this hot air balloon should naturally be handed over to a professional like Ma Jun to study. Immediately, Zhou Fan was sent to invite Ma Jun to go.

"I've seen the lord!" Half an hour later. Ma Jun appeared on the school field, Zhou Fan ordered him to come over, he naturally didn't dare to slack off, and rushed over quickly.

Immediately, Zhou Fan told him about the hot air balloon and Ma Jun. Let's see if he can solve the problem of the hot air balloon bursting when it flies high in the air.

At the beginning, Ma Jun heard that Zhou Fan was tinkering with this hot air balloon just to make the beauty smile, and he was still a little dissatisfied in his heart, and his ability should be put on more important research. But this Zhou Fan is his lord after all, his parents, he and his horse have all his current status all rely on him Zhou Fan, so even if he is a little dissatisfied in his heart, he still does not refuse.

However, then he slowly listened to Zhou Fan's idea of this hot air balloon, and was immediately frightened, he Zhou Fan was able to make this kind of thing that could fly into the sky without wings. Immediately, he was anxious, this kind of invention was something he had dreamed of for a long time, and he didn't care about any etiquette, so he hurriedly urged Zhou Fan to get another Kong Ming lantern to come out and take a look.

Zhou Fan didn't mind, and made a Kong Ming lantern like before again, and in front of Na Ma Jun, he pointed to the sky again.

Ma Jun's whole person was petrified, listening to Zhou Fan's story and watching this Kong Ming lantern fly into the sky with his own eyes, these are completely two feelings.

Zhou Fan looked at Ma Jun, the inventive maniac, a little helplessly, and quickly woke him up, now is not the time to be in a daze, and he has to rely on him to perfect this hot air balloon.

Ma Jun, the inventor, didn't care anymore, and he couldn't care about Zhou Fan and them, and he started research around the broken hot air balloon, constantly tossing there.

"Lord, I understand, I understand." After a while, the horse ran over excitedly.

Everyone is overjoyed, could it be that this horse has found a solution so quickly, so doesn't it mean that this hot air balloon can fly again.

"Lord, the reason is here, although the flame after the pine resin burns did not directly touch the paper outside, but after a long time, the heat outside the flame is enough to burn the paper, so your hot air balloon will fall directly." Ma Jun said with some excitement.

Hearing this, Zhou Fan's heart shook slightly, and he suddenly became uplifted, feeling that he had completely forgotten one thing.

The paper he used to paste this hot air balloon now was much better than the Caihou paper, but the conditions of this era were limited after all, and it could not be compared to the paper of later generations anyway.

In later generations, when Zhou Fan saw people put Kong Ming lanterns, the smaller Kong Ming lanterns were fine, but if they were slightly larger, they would not be the current paper.

"Then why don't we replace the paper with cloth or hides?" Zhou Yu also understood what Ma Jun meant in an instant, and hurriedly proposed.

"No! Paper is a must! Zhou Fan refused without hesitation. Although the cloth and animal skins will not be burned by the heat, they are breathable, Zhou Fan remembers that those hot air balloons in later generations are made of impermeable reinforced nylon, the paper is fine, if it is replaced with breathable cloth, maybe it will not be able to fly.

"Yes, what the lord said is that they all think that paper should be used outside, but you can paste a layer of leather on the inside of the paper, so that there should be no problem like before." Ma Jun thought for a while and said. (To be continued......)

ps: About this hot air balloon, it is purely Hu Zou, if there is anything wrong, don't blame you
