Become a mayor from today

Liu Feng thought for a while, and then said. "It must also dissipate a large amount of hot air, which is the key to a hot air balloon going to the sky."

He hopes that the hot air balloon can float in the sky for several hours without having to come down to refuel. Although one person can go up, and if the other places are filled with fuel, it can float for a longer time, but this is a bit tasteless.

"Yes." The old carpenter wrote it down, and he will pass it on to other research institutes. They are not in charge of the fuel, and there are research institutes dedicated to fuel research.

"Master, can I also take a ride in a hot air balloon?" An Li whispered, looking at Liu Feng expectantly with her brown eyes.

After the words fell, Mina and Eliza also stared fixedly at Liu Feng. This experience of being able to go to heaven is a once-in-a-lifetime opportunity.

Chapter 0408 wants to fly back to my hometown to see.

"Of course." Liu Feng smiled lightly. He would definitely satisfy Hu Erniang for such a small request.

"Yeah! That's great." An Li jumped up happily, with a brimming smile on her face, and a little nervousness in her eyes.

"Let's go." Liu Feng stretched out his hand to Hu Erniang with a smile, then turned to Mina and Eliza and said, "Just wait a moment."

An Li looked at Liu Feng's outstretched hand, her cheeks flushed slightly, this was the first time the young master asked her to hold hands, her small hand was lightly placed on Liu Feng's palm, and was held by Liu Feng immediately.

"Yes." The cat-eared lady said softly.

Eliza nodded slightly with emerald green eyes, "Okay."

Liu Feng took An Li into the hot air balloon. The charcoal had already been replaced once by the old carpenter. He pushed the bellows and followed the command of 'loosen the rope'. The old carpenter let go of the rope, and the hot air balloon slowly lifted off again.

The fox-eared lady was very nervous. After all, it was her first time to go to the sky, and she was snuggling in Liu Feng's arms. She looked around in surprise with her brown eyes, feeling the uplift of the hot air balloon, and her fox tail flicked back and forth on Liu Feng's thigh.

"Don't be afraid." Liu Feng felt An Li's nervousness, patted Hu Er Niang's back, and comforted her, "As long as the hot air balloon doesn't fly very high, it's very safe."

"Hmm!" An Li nodded her head lightly, her fox ears trembled, her nervous heart gradually calmed down, and she asked in a crisp voice, "Master, why can a hot air balloon fly by burning charcoal?"

"Hmm~~ How should I put it?" Liu Feng paused, thought for a while and said, "Anli, this world is more complicated than we imagined. For example, there are many things in the air that we can't see with our naked eyes."

"Ah? Is there something in the air?" An Li looked around with her big brown eyes wide open, but she couldn't help but pouted and muttered, "Master, are you kidding me? Is there something in the air?" what."

"No? Then think about it? Why do we breathe?" Liu Feng raised the corner of his mouth and said softly, "What is the breath we breathe?"

"This..." Enli's eyes were dull, yes, why are we breathing?What is the exhaled breath?Is there really something in the air?

"Let me ask you another question." Liu Feng looked at the stunned fox-eared lady, and said slowly, "Why can wood float on the water?"

"This..." An Li frowned, holding her chin in her little hand and thinking, why does the wood float on the water? Isn't it because water is like this?

No, why can the fish be in the water?Why can the stone sink?Can dirt sink?

Could it be the weight?No, the wood is so big, the stone is so small, and the weight of the two is not the same. Huoji?

Hu Erniang's clever mind can think of many things at once, but something is missing, and she can't figure out what it is that makes her think hard.

"Whoosh..."

Liu Feng pushed the bellows, and looked at Hu Erniang with a smile on his lips. This is the knowledge of junior high school courses on the other side of the earth. If no one breaks through the mysterious fog, they may be confused for a long time.

"Master, why? Why can stones sink to the surface of the water, but wood floats on the surface?" An Li pouted, looking at Liu Feng bitterly. She really couldn't figure it out. What is the reason for the two?

"Density." Liu Feng spit out a word softly.

Hu Erniang looked at Liu Feng in a daze, shook her head and asked, "Master, what is density?"

"Density is the mass per unit volume of a substance. It is a characteristic. Is iron very hard? Is water flowing? With the same volume, is wood less hard than stone? This is the characteristic of the substance, and it is also determined by the density. Yes." Liu Feng roughly explained.

"..." An Li lowered her head ignorantly, thinking about it, she still didn't quite understand, all she knew was that stone is of course harder than wood, so could it be the density?One is harder?One is softer?

"And our air also has its own characteristics." Liu Feng pushed the lower bellows, and continued, "We see that the hot air will float up. That's because the density of hot air is low, and the density of cold air is high, which creates buoyancy."

"Huh? Is that so?" An Li's brown eyes flashed, and she quickly looked at the charcoal on the shelf, and saw that the hot air was really floating upwards. Could this be the secret of the hot air balloon?

"That's it." Liu Feng smiled lightly. He was quite surprised that Hu Erniang was able to accept such knowledge so quickly when she came into contact with it for the first time.

"Density, volume, characteristics..." An Li muttered, and immediately took out a notepad to write it down. She found that this was a truth that could make people understand the essence of this world, and it was also the secret of hot air balloons.

The hot air balloon was pulled by the rope, and soon stopped rising. Liu Feng quietly looked into the distance. Today is the beginning of an epoch. He has already started to touch the sky, which is thousands of years earlier than the human race of this era. As for the racial talent of the bird-clan orcs, he really couldn't compare them.

"It's so beautiful." An Li came to the hanging basket. She looked up at the top of the Forbidden Mountains in a daze. It would be great if she could fly there. Maybe she could see the Brutus Beastman Kingdom?

"Sick of home?" Liu Feng pushed the bellows, also looking at the top of the Forbidden Mountains, he could feel the loss suddenly displayed by Hu Er Niang.

"I'm just curious about how things have changed in my hometown." An Li's voice was low, without the usual crisp and joyful, Fox Ears lay down.

hometown?When Liu Feng heard this word, his heart warmed slightly. Hu Erniang really regarded Xiyang City as her new home, otherwise she wouldn't call the former Brutus orc kingdom her hometown.

"Master, can this hot air balloon fly over the top of the mountain?" An Li turned around and asked, her normally energetic face was now full of frailty, and her brown eyes gleamed with expectation.

"Of course." Liu Feng nodded affirmatively, stretched out his hand to caress the cheek of Hu Erniang, and said with a gentle smile, "In a little while, when I develop a more powerful hot air balloon, I will take you back to my hometown to have a look."

"Really?" An Li's brown eyes widened, her little hands clenched the big palms on her cheeks, she really wanted to fly back to her hometown to have a look, this was probably a regrettable wish.

"Really." Liu Feng responded seriously, stroking the slippery crystals of Fox-Er Niang with his thumb.

"Master, that's great."

An Li rubbed her cheek against Liu Feng's palm, and suddenly hooked her hands around his neck, trying to get close to him on her tiptoes...

Chapter 0409 is rare without me.

Liu Feng was stunned for a moment, looking down at Hu Erniang's blushing face, trembling eyelashes, and trying to get her head up with her face up, but because of her height, she was barely able to kiss him.

This made Liu Feng feel funny and pitiful, and slowly lowered his head to stick it down, kissed Anli's small mouth, wrapped one hand around the waist of Fox Erniang, and hugged her into his arms.

The two had a sweet kiss high in the sky. After kissing for a long time, the two parted, each other's lips were rosy, and the fox-eared lady looked at Liu Feng shyly, and put her head in his arms, quietly do not speak.

This can be regarded as An Li's bold behavior. Don't think that Fox Er Niang is usually perverted, ahem, she is quite bold and playful, but the other party is all familiar female friends, and she is still very shy when facing Liu Feng.

Liu Feng patted Hu Er Niang's back, and occasionally pulled the bellows with one hand, so that the charcoal flames could fully emit heat.

The two enjoyed the tranquility of this moment. An Li was the second orc that Liu Feng had a close relationship with. She usually behaved strangely, like a girl, with a seemingly petite figure, but her actual age was older than Mina. one year old.

She has a different care and entanglement with breasts than ordinary people, and it is also the glue for many beast-eared women in the castle. It is also because of her playfulness that everyone is well integrated into the life of the castle.

If Liu Feng were to evaluate who helped him the most and Xiyang City the most, he would say that it was An Li, and that some of the government affairs were all handled by Hu Er Niang.

"Master, are you stressed?" An Li suddenly asked, looking up at Liu Feng's face, and said seriously, "Did we put a lot of pressure on you?"

With so many orcs living in Xiyang City, Liu Feng must be under the greatest pressure. Not many nobles of the human race are close to orcs.

"Say something stupid, the pressure doesn't exist."

Liu Feng shook his head, he looked at the distant sky, raised his hand and said, "Sometimes pressure is also motivation, and you are a kind of spur to me, let me know that I can't stop moving forward, one day, I will Let all races live together in harmony."
