Become the city lord from today

"Of course." Liu Feng chuckled, such a small request, he would definitely satisfy the fox ear girl.

"Yay! That's great. Allie jumped up happily, with a smile on her face, anticipation and a little nervousness in her eyes.

"Let's go." Liu Feng stretched out his hand to the fox ear lady with a smile, turned his head to Mina and Eliza and said, "You guys just wait a minute." "

An Li looked at Liu Feng's outstretched hand, her cheeks flushed a little, this was the first time that the young master took the initiative to let her hold hands, and the small hand was lightly placed on Liu Feng's palm, and was held by Liu Feng.

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

Eliza's green eyes curved slightly, and she nodded, "Okay." "

Liu Feng took Allie into the hot air balloon, the charcoal has been replaced by the old carpenter once, he pushed the bellows, with the command of the 'loose rope', the old carpenter loosened the rope, and the hot air balloon slowly lifted off again.

The fox-eared lady was very nervous, after all, the first time she went to the sky, she snuggled in Liu Feng's arms, her brown eyes looked around in amazement, feeling the rise of the hot air balloon, and the fox's tail flicked around at Liu Feng's thigh.

"Don't be afraid." Liu Feng felt An Li's nervousness, patted the fox ear lady's back, and soothed, "As long as the hot air balloon does not fly very high, it is very safe." "

"Uh-huh!" An Li nodded lightly, the fox's ears trembled, her nervous heart slowly calmed down, and asked crisply, "Young Master, why can a hot air balloon fly by burning charcoal?" "

"Hmm~~ How to say it?" Liu Feng paused, thought about it and said, "Allie, this world is more complicated than we think, such as this air, there are many things that we can't see with the naked eye. "

"Huh? Is there something in the air? Allie widened her brown eyes, looked around, saw that her eyes were sour and didn't see anything, couldn't help pouting, muttered, "Young Master, are you teasing me?" There's something in the air. "

"Didn't you? So you think? Why do we breathe? The corners of Liu Feng's mouth rose, and he said softly, "What is the breath we breathe?" "

"This..." Allie's eyes were glazed, yes, why are we breathing? And what is the breath that comes out? Is there really something in the air?

"One more question for you." Liu Feng looked at the stunned fox-eared lady and said slowly, "Why can wood float on the surface of the water?" "

"This..." Allie frowned, holding her chin in her small hand and thinking, why did the wood float on the water, wasn't it because the water was like this?

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

Is it weight? No, the wood is so big, the stone is so small, and the weight of the two is not the same, is it resting?

The fox-eared lady's intelligent brain is a lot at once, but there is something missing, and she can't figure out what it is.

"Whew..."

Liu Feng pushed the bellows, and looked at the fox ear girl with a smile at the corner of his mouth and was thinking hard, this can be regarded as the knowledge of the junior high school curriculum on that side of the earth, if no one breaks through that layer of mysterious fog, it will be confused for a long time.

"Young Master, why? Why can stone sink to the surface, but wood floats on the surface? An Li pouted and looked at Liu Feng bitterly, she really couldn't figure it out, why are these two?

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

The fox-eared lady looked at Liu Feng in confusion, shook her head and asked, "Young Master, what is density?" "

"Density is the mass per unit volume of a substance, is it a characteristic, is iron very hard? Does water flow? In the case of the same volume, is wood not as hard as stone? This is the property of matter, and it is also determined by the density. Liu Feng probably explained.

"..." Allie lowered her head in ignorance, thinking about it, she still didn't understand much, only knew that of course stone was harder than wood, could this be density? One is harder? One is softer?

"And our air also has characteristics." Liu Feng pushed down the bellows and continued, "We see that the hot air will float, and that is because the density of hot air is small, and the density of cold air is large, which creates buoyancy. "

"Huh? Is that so? Allie's brown eyes flashed, and she quickly looked at the charcoal on the shelf and saw that the heat was really floating up, could this be the secret of the hot air balloon?

"That's it." Liu Feng chuckled, he was surprised that the fox ear lady was able to accept such knowledge so quickly for the first time.

"Density, volume, characteristics..." said Allie, immediately took out a notepad and wrote it down, she found that this is a truth, which can make people recognize the essence of this world, and it is 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 an epoch-making beginning, the sky field, he has begun to contact, thousands of years earlier than the Terrans of this era, as for the racial talent of the bird race orcs, he really can't compare.

"It's beautiful." Allie came to the hanging basket, she looked up at the top of the Forbidden Mountain Range and was stunned, if only she could fly over, maybe she could see the Brutu Orc Kingdom, right?

"Homesick?" Liu Feng pushed the bellows, and also looked at the top of the Forbidden Mountain Range, he could feel the sudden loss of the fox ear girl.

"I'm just wondering how it's happened in my hometown." Allie's voice was low, without her usual crisp joy, and her fox ears fell down.

Home? When Liu Feng heard this, his heart warmed slightly, the fox ear lady really regarded Xiyang City as her new home, otherwise she would not have called the former Brutu Orc Kingdom her hometown.

"Young Master, can this hot air balloon fly over the top of the mountain?" Allie turned and asked, her usually vibrant face was now full of softness, and her brown eyes flashed with expectation.

"Of course." Liu Feng nodded affirmatively, reached out and touched the fox ear lady's cheek, and said with a gentle smile, "In some time, when a more powerful hot air balloon is developed, I will take you back to your hometown to have a look." "

"Really?" Allie's brown eyes widened, her small hand clenched the wide palm on her cheek, she really wanted to fly back to her hometown to see, this is a regrettable wish.

"Really." Liu Feng responded seriously, and his thumb caressed the crystal that slipped away from the fox ear girl.

"Young Master, it's so good."

An Li's cheek rubbed Liu Feng's palm, her hands suddenly hooked around his neck, and she tried to stand on tiptoe to get closer to him...
