In the afternoon, everyone took the Chituma No. 4 to return.
On the way back, everyone stopped playing games, but Kenichi was still so panicked that he took the initiative to take over the human-powered engine job. He was really fed up with flying. It is estimated that he will not touch flying, not even airplanes, for the next week. He didn't even want to sit down.
All the flying experiences in his life were experienced at once in the morning. The taste was so sour and refreshing. If he hadn't been a father, he would have hugged his master's lap and cried loudly to tell them not to try it. Akong The things created by that bastard are always only suitable for himself!
Little Shizuka went to cheer up her heroic and tragic father, and Miyu also went to share her husband's pressure.
Seeing this, the others stopped disturbing the family of three's warm moment and took the initiative to stay on the deck.
The elder was at the helm, Misakiji Akiyu observed the direction, and the others fished.
"By the way, there's something I forgot to mention. When I flew to a place with gorgeous aurora, I felt that just taking a breath there can invigorate the energy in the body, which is comparable to taking a big tonic!" Xing Yekong suddenly said Thinking of this incident, he quickly said to everyone.
"Are you talking about the ionosphere?" Misakiji Akiyu, who was standing on the mast looking out over the sea and commanding the direction, couldn't help but ask after hearing this.
"That's right. The layer higher than the stratosphere is very different. Even the air tastes different. I don't know if it's an illusion. I feel sweet and smelly." Hoshino Sora said and smacked his mouth.
Everyone: "..."
"Are you bullying me for not studying enough?" Ni? Zhixu's eyes widened and he complained, "Although I only have a college degree, I still know that the higher the place, the rarer the air, especially the ionized layer. , you can tell from the name, is there normal air there?"
Hoshino Sora explained: "Maybe ordinary people can't stand it all at once, but if you are an expert, you should feel very comfortable and have a feeling of returning to the embrace of nature."
"Ah..." Ma Jianxing blinked and spread his hands, "We can't refute you. After all, we haven't been there, don't understand, and can't say much."
"Uncle Ma, how about I jump up and throw you up in the air? This will put less burden on you and send you up to experience it?" Hoshino Sora thought for a while and put forward a solution.
"..." Ma Jianxing twitched the corner of his mouth, "If you want to punish me, just say it straight away, no need to beat around the bush."
At this time, after making sure that the front was stable, Misakiji Akiyu said, "I think what Akora said is comparable to a great tonic...it's negative ions."
"Negative ions?" Everyone muttered this word in confusion.
"Is it an anion in which an atom gains an electron?" Hoshino Sora is in high school, which is probably the stage where he has the most scientific knowledge in his life. He still understands this basic concept, but he often gets confused.
"Essentially there is no difference. Anion is mainly a chemical concept, while negative ions are a physical concept." explained Misakiji Akisame.
"Oh~" Hoshino Sora couldn't help but scratch his head, returning to the fear of being dominated by physics and chemistry teachers.
These conceptual things have always given him a headache. Charges, left-hand rules, equation balancing, this is simply magic!
"I'm tired if you guys want to talk about this." Ni? Zhixu complained.
"Hahahaha~" Misakiji Qiuyu touched his mustache, smiled heartily, and then said seriously, "Everyone must have been exposed to the so-called negative ions."
"Could it be that it also exists in normal air?" Ma Jianxing asked in surprise.
Misakiji Temple Qiu Yu nodded and said: "It does exist, but more often in deep mountains and old forests with dense vegetation. Why do everyone like to retreat in virgin forests that have not been developed by humans?"
When the elder who was steering the helm heard this, he laughed and said, "Martial artists throughout the ages like to go there to practice!"
