The little babies who returned home after class that day all gathered around Fang Jing, wondering how Fang Jing's hot gas experiment was made, or even wanting Fang Jing to make a Kong Ming lantern.

"I don't have time today, let's make a better hot air balloon in a few days." Fang Jing was a little unbearable to be surrounded by this group of little babies, even Fang Yuan came to join in the fun, haven't you seen the sky?

"Brother Jing, you don't have to go to school tomorrow anyway, you can do it now." She didn't want to let Fang Jing go, and she kept talking about this flying Kong Ming lantern.

"If you don't do it, you can do whatever you want, don't surround me." Fang Jing got up from the chair and hurriedly left the house, otherwise he would have a pile of bones left in a while.

"Brother Jing, don't run, grab Brother Jing." Seeing that Fang Jing was about to leave, Lizhi shouted loudly that the other little babies surrounded Fang Jing, and were about to catch and kidnap Fang Jing.

"I'll go, you little girls, you're still lawless, and you're going to arrest me, it's useless to arrest me, I just won't do it." Fang Jing was grabbed by the little girls at home and didn't let her run, she really had a headache to look at, anyway, she wouldn't do anything Kong Ming lantern, the dead pig was not afraid of boiling water, why don't you love it.

"Brother Jing, you just do it." Lizhi is planning not to let go of Fang Jing, and she has begun to use her usual tricks again, coquettish and cute.

"I really don't do it, I won't do it if you are coquettish, you listen, Xiao Linghua is awake, I have to coax Xiao Linghua." Fang Jing heard Xiao Linghua's cry, and quickly pushed aside the group of little babies, and went into the house to pick up Xiao Linghua.

"Hmph, Brother Jing is stingy now, every time." Li Zhen pouted and watched Fang Jing come out with Xiao Linghua in her arms.

"You can do whatever you have to do, after a while, your aunt and mother will have to cook when they come back, you should also hurry up and go to the bamboo forest to see Xiong Er and them, get them back and wash them, every day when you go to the bamboo forest, it is dirty." Fang Jing hurriedly opened her mouth to find a job for the little babies, so as to save herself from annoying.

After hearing this, the little babies no longer pestered Fang Jing and went to the bamboo forest, which made Fang Jing feel very relieved, if he really wanted to be besieged by this group of little babies, he couldn't fight back.

"Jing Wazi, Xiao Linghua give me a hug, you go make milk powder." Chen Erlin walked over and said to Fang Jing.

"Uncle, your injuries are not healed yet, so let's have a good rest with Dachu." Although it is a little inconvenient for Fang Jing to hold Xiao Linghua to make milk powder, it can be done with one hand.

"Jing Wazi, it's okay, I'm just a small injury, it's not a big injury, give me Xiaolinghua." Chen Erlin insisted.

"That's okay, uncle, if it's inconvenient, you can tell me." Fang Jing had no choice but to hand Xiao Linghua to Chen Erlin to hold it, not forgetting to tell her.

"I know." After Chen Erlin took Xiao Linghua, he coaxed the child, and Fang Jing went to the stove room and began to fetch water to boil water, preparing to brew milk powder for Xiao Linghua.

Chen Erlin and Da Chu, in fact, by now, the injury on their head is basically fine, and after so many days, it has long since scabbed.

In the following time, Fang Jing began to think about how to make a hot air balloon, several sketches were drawn, the hanging basket was basically a basket made of bamboo, and the weight was relatively light, but Fang Jing always felt that it was not good-looking, and it was not practical, so he thought about asking Fang Da to come over and help make a hanging basket.

"Uncle Dayong, I want to ask you to help me make a big hanging basket, this is a drawing, you can see if you can make it up." Fang Jing came to Fang Da's house, and it happened that Fang Dayong was making up something.

"Jing Wazi, this big hanging basket is not difficult, it's very simple, but is it any use for you to make such a big hanging basket? If you need it urgently, you can take one from my house. After Fang Dayong saw Fang Jing coming over, he looked at the sketch in Fang Jing's hand and said.

"Uncle Dayong, this big hanging basket is useful to me, otherwise I wouldn't ask Uncle Dayong to help me make a specific one." Fang Jing didn't want to use any other hanging baskets or baskets.

"That's okay, you can just cut five bamboos and come over, and I'll weave it for you when the time comes." Fang Dayong listened to Fang Jing's words, and estimated that this big hanging basket had a different use.

"Okay, I'm going to cut the bamboo." After Fang Jing got a response, he walked home, picked up a broken knife and went to the bamboo forest to cut down five bamboos to resist Fang Dayong's house.

The next thing is to solve the furnace device, for this point, Fang Jing thought very clearly, there is no blacksmith shop in Fangjia Village, not to mention that the blacksmith is too heavy, he has to ask the dumb fairy for some alloys, one is to reduce the weight, and the other is the sealing problem.

The construction of the furnace device, Fang Jing basically solved it in his own building, so that Chen Erlin and Huang Meihua could hear the sound of the diesel generator every day, although they were curious, fortunately, Chen Erlin and his wife had already known that Fang Jing must be creating something strange, and after explaining to Huang Meihua, it was also casual.

It took Fang Jing a few days to complete the furnace device, check the various solder joints, and did not find the existence of water and gas leakage, Fang Jing breathed a sigh of relief, from the beginning to the present, basically every day has not stopped, as long as there is time, will come to build this furnace device.

The device of the furnace is simple, but for Fang Jing to only read books to make, in fact, it is very troublesome, Fang Jing uses four flamevents, two use liquefied gas, of course, oil can also be used, and the other two use the type of coal to generate kinetic energy, otherwise, if you directly ask the dumb fairy for a fire-breathing device, it will be much simpler.

Why do you want to use four flame-vents, in fact, this is also after Fang Jing has seen many introductions to the principle of hot air balloons, he decided to do so, it is just a backup, just in case one burner is stopped, there is another spare, so that it will not fall down and fall into a meatloaf.

As for the entire hot air balloon sphere, Fang Jing couldn't think of any materials in Datang to solve it, so he could only ask for one from the dumb fairy, the color was white, without any pattern, and it was really going to be lifted off during the experiment in the future, and a few words could be added to it at that time.

A few days later, it happened to be the second day of the holiday, Fang Jing notified all the students to gather at the school square, and called a lot of older babies to come to the house and resist all the hot air balloon things into the wasteland not far from Fangjia Village.

Fang Jing didn't want to raise the hot air balloon on the other side of the square, this was not a good idea, even if it could be raised, Fang Jing was afraid that the wind would blow the hot air balloon in the direction of the big banyan tree, and then it would become a joke.

"What are you doing, sir?" Qian Shi and Cheng Siping, the generals and captains, also came over to see the excitement, who told Fang Jing to make such a big move, and there were also a lot of villagers, and the village was too idle to come over to see the excitement.

"Jing Wazi, what are you doing here?" Muramasa looked at this large pile of cloth, and he didn't know what kind of cloth it was made of, but after touching it, it felt very smooth.

"You all go to the side and watch, I'm going to do this hot air balloon experiment in a while, so that the little babies can gain knowledge, Qian Shi, Cheng Siping, you come over to help." Fang Jing blasted these villagers and students away, saving them from having trouble explaining everything.

"Qian Shi, you hold these ropes, pull them up and pull them higher, I'll light the fire." Fang Jing taught Qian Shi how to fiddle with them. But he came to the edge of the stove, lit the fire, opened the two flamevents, and began to look at the hot air in the sphere.

"Sir, it's too hot for me here, how long will it take?" The position where the Qian waiter was standing was just downwind, and the heat was blowing directly to his side, so hot that he couldn't stand it anymore.

"Come on, hold on for a while." Fang Jing began to adjust his position so that the air intake of the sphere was aimed at the incoming wind, so that Qian Shi could not be attacked by the hot air.

"Alright, you can go." After Fang Jing adjusted, he shouted directly to Qian Shi and Cheng Siping, and began to increase the flamevent.

There was a large bucket of diesel fuel in the big hanging basket, and he was shaking the head of the oil delivery while holding it, so that the diesel in the barrel could be sent to the flamevent for combustion, Fang Jing originally wanted to design an automatic device, but there was no good way, so he could only use this manpower mode for the time being.

After two quarters of an hour, the sphere was fully flaunted, and a huge sphere began to slowly unfold into the eyes of everyone.

"Wow, that's big." The little babies raised their heads and looked at the puffed up spheres, and their hearts were greatly admired.

"So big? What are you doing here? Such a good cloth, aren't you afraid of being burned? "A villager looked at such a large sphere, and his heart felt sorry for these cloths.

"Commander Qian, what is this thing for, sir?" Cheng Siping looked at the sphere and puffed it up, and after watching it for a long time, he didn't understand what it was.

"I don't know, sir's stuff is not something we can guess." Qian Shi opened a pair of big eyes, looking at the huge sphere in front of him, and wondered in his heart what Fang Jing was doing with this thing.

"Wow, Brother Jing is amazing, such a big Kong Ming lantern, if it is put in the sky, it will definitely fly so high and high." Lizhi looked at the hot air balloon with her little head up, and in her eyes, it was just a big Kong Ming lantern.

"My brother is the best." Fang Yuan stood beside Lizhi, and after listening to Lizhi's words, he agreed greatly.

As time passed, the hot air balloon was officially in place, and Fang Jing directly turned off a flamevent and climbed into the hanging basket.

"Qian Shi, come and untie the rope down here." Fang Jing shouted loudly to Qian Shi, and called Qian Shi to untie the rope tied to the ground, so that the hot air balloon could start to rise into the air.

"Yes, sir." After hearing this, Qian ran over directly, untied the rope, and ran back to stand and watch.

Fang Jing waited for the heat in the sphere to completely expel the air inside, and after a quarter of an hour, it began to rise slowly, Fang Jing felt the movement of the big hanging basket, looked at the ground, and made sure that it was ready to be lifted into the air.

"Wow, it's up, it's up." The little babies shouted when they saw the hot air balloon rise to a height of more than a meter.

"Jing Wazi, hurry down, don't go up again, what if something happens?" Mura Zheng watched the big ball rise in front of him, but he didn't see Fang Jing climb down from the big hanging basket, and his heart was very anxious.

"Muramasa, it's fine." After Fang Jing heard Muramasa's shout, he also shouted in response.

After another hour or two, the air in the balloon is estimated to have been expelled about eight or nine layers, because the speed of the rise has begun to accelerate, and it is nearly ten meters above the ground.

"Wow, wow." The little babies raised their heads and looked at the big Kong Ming lantern that had risen into the sky, and they didn't know what words to use to describe the current appearance.

"Commander Qian, this ...... This....... Cheng Siping watched the hot air balloon in the sky begin to rise faster, his eyes widened, he didn't believe it was true at all, and shouted out to Qian Shi in his mouth.

At this time, Qian Shi was also like Cheng Siping, staring at the sky as if he was enchanted, and he didn't hear what Cheng Siping said.

"This ...... This...... This....... The villagers did the same, looking at the hot air balloon in the sky, as if they were seeing a monster, they didn't know how to describe what was going on in their hearts, their eyes were so big and round, they were so frightened by this scene that they couldn't speak.
