"Huh, how strange is that? Your palm is bigger than the Great Bamboo Peak. Tian Xin'er asked puzzled.

"Hehe, this is because my palm is close to you, so you look at my palm is big, and the big bamboo peak is far away from you, so you think the big bamboo peak is small.

In fact, the closer to you is something, the bigger you look at, if you cover your eyes with a date, I'm afraid you won't even be able to see the whole world, can you say that the date is bigger than the whole world? Huo Xiaotian patiently explained.

Although Tian Xin'er has good qualifications for cultivating immortals, she has not received scientific education since she was a child, not to mention mathematics, physics and chemistry, but she does not understand the basic mathematical laws and physics knowledge.

However, this is not unusual, in the Celestial Empire a hundred years ago, in fact, many people did not have common sense of physics, and often made jokes such as "the power of the horse-drawn carriage is greater than the power of the carriage pulling the horse, so the carriage will go forward".

"I see, so the farther away from us, the smaller we look?" Tian Xin'er asked thoughtfully.

"Yes, for example, the planet Adella in the sky is almost 400,000 kilometers away from us in a straight line, which is almost 200,000 times the height of Dazhuzi Peak.

At such a distance, we look at the planet Adella, just the size of a moon cake, but its actual volume is almost the same as our star Sumemir, if we put our big bamboo peak at such a distance, I'm afraid we can't even see the shadow of the big bamboo peak. Huo Xiaotian said with a smile.

Tian Xin'er listened attentively, this was the first time she had heard someone tell her about astronomy and physics, although this knowledge had almost nothing to do with cultivating immortals. But. She was still interested.

"How do you know that Adela's planet is so far away from us?" Tian Xin'er asked curiously.

"That's a good calculation. In fact, according to the rotation period of the planet Adella and the rotation period of our star Sumeimir, the distance between the planet Adella and us can be determined, and in addition, the volume, mass and density of the planet Adella can also be calculated. Huo Xiaotian explained with a smile.

Tian Xin'er listened to it for a while, because she didn't have any physical foundation before, she calculated so easily what Huo Xiaotian said. I don't know at all.

"Forget it, these things are too difficult for you, I'll tell you about them when I have a chance later, right?" Huo Xiaotian shook his head with a smile, and immediately took out a box of cigarettes from his trouser pocket, lit it with a lighter, and inhaled it vigorously, and suddenly a fragrant smell of tobacco spread from the air.

Tian Xin'er looked at this scene strangely, her beautiful eyes full of surprise.

"Huh? Do you know fire magic? Tian Xin'er asked strangely.

"What?" Huo Xiaotian looked at Tian Xin'er strangely. I saw Tian Xin'er staring at the lighter in Huo Xiaotian's left hand with a pair of beautiful big eyes, and she could see it.

"You say this? This is a lighter. Huo Xiaotian said. As soon as the button was pressed, the lighter "banged" and a small flame erupted.

Tian Xin'er felt even more novel, because there was no lighter on Sumeimir Star, so Tian Xin'er had never seen a lighter, and seeing Huo Xiaotian using a lighter to light, it was naturally very fresh.

"Can I try it?" Tian Xin'er stretched out her little hand and asked.

Huo Xiaotian took a puff of cigarette, nodded with a smile, and handed the lighter in his hand to Tian Xin'er.

Tian Xin'er took the lighter and pressed it down carefully with her thumb, only to hear a "poof" sound, and a flame erupted from the nozzle of the lighter, a little frightened, but more fresh.

After pressing it a few times in a row, Tian Xin'er was quickly attracted by this fresh gadget, and she felt a little in love with it.

"Hehe, if you like it, I'll give it to you." Huo Xiaotian said generously.

Actually, this lighter is not expensive, and it can be redeemed for only one point in the super download system, so it is not a valuable item.

Tian Xin'er was very happy when she heard that Huo Xiaotian sent her a lighter, smiled and said thank you, and continued to play.

After playing with the lighter for a while, Tian Xin'er was suddenly distracted by the smoke spit out of Huo Xiaotian's mouth, only to feel that there seemed to be some strange tobacco smell in the smoke, which smelled strange.

"What are you eating?" Tian Xin'er pointed to the cigarette in Huo Xiaotian's mouth and asked.

"It's a cigarette, it's not to eat, it's to be smoked." Huo Xiaotian said with a smile.

"What are you doing by sucking this?" Tian Xin'er had never smoked, and she had never seen anyone smoke, so she was also very interested in the cigarette in Huo Xiaotian's mouth.

"Well, I can't say clearly, in short, when I'm bored, I like to smoke two sticks, which can refresh me." Huo Xiaotian spat out a puff of smoke rings and said with a smile.

Tian Xin'er was attracted by Huo Xiaotian's smoking posture, to be precise, when Huo Xiaotian smoked, he was very manly, coupled with the effect of tobacco, Tian Xin'er was even more interested in the cigarette in Huo Xiaotian's mouth.

"Can you give me a try?" Tian Xin'er asked with a smile.

"Hehe, okay, you can try it." Huo Xiaotian smiled and handed the cigarette to Tian Xin'er.

Tian Xin'er took the cigarette, put it to her lips, followed Huo Xiaotian's example, and took a sharp breath, but when the hot smoke invaded her throat, Tian Xin'er didn't feel very comfortable, but felt a hot and choking smell, Tian Xin'er coughed violently, while coughing, beating her chest, uncomfortable tears were about to fall.

Huo Xiaotian looked at Tian Xin'er's embarrassed appearance and couldn't help laughing.

And at this time, Song Xiaoren, who had been looking for two people for half a night, happened to find here, heard Tian Xin'er's painful ** voice, and heard Huo Xiaotian's debauched laughter, a bad thought instantly came to Song Xiaoren's heart.

"Oh no, junior sister, shouldn't she have been given by Huo Xiaotian..."Thinking of some terrifying possibility, Song Xiaoren's imperial sword fell straight down, but in an instant, he had already come to Huo Xiaotian.

Huo Xiaotian was smiling happily, and suddenly saw Song Xiaoren coming, and couldn't help but be startled.

"Brother Song? What are you doing here? Huo Xiaotian looked at Song Xiaoren and asked.

"Hmph, Huo Xiaotian, I really didn't see it, I thought you were an honest person before, but I didn't expect you to be a hypocrite with evil intentions, tell me honestly, what did you do to my junior sister?

If you don't tell the truth, I will pierce your heart with a sword and make your blood splash! Song Xiaoren's eyes were stunned, and a cold murderous aura suddenly surged over. (To be continued.) )
