Wang Qinian was very surprised and said: "It is worthy of being a master of the spiritual department, you guessed it well, it is a lifeboat." ”

"What's the use of a lifeboat, you can go up here are all magic masters, when you encounter danger, you can escape with a levitation technique, and you don't need a lifeboat at all. Jessica said.

"Yes, you're right. But you ignore one point, people buy it is not that it can save lives, but that it can be displayed, is a symbol of status, the reason why the city in the sky is not equipped with a lifeboat, it should not be called a lifeboat, but a private yacht, its speed is much faster than the city in the sky, you can build three grades, one is the simple type, very simple, can carry two to three people, the function is to be able to travel back and forth between the city in the sky and the ground, the magician or alchemist can use the magic core or magic crystal as the power; one is the practical type, can carry five to ten people, can also transport goods, mainly used as a magic merchant to transport goods; there is also a luxury type, on the basis of the practical type, as much as possible luxury, can you do this business?" Wang Qinian said.

"You seem to have a point, what are you going to do? I remember that your bicycle makes a lot of money, and if this thing works better, it may be able to set off a new wave among magicians, but unfortunately magic is still too far behind ordinary people to be popularized by ordinary people. Jessica sighed.

"Give wings to ordinary people like me. Xiaoshuang shouted.

Wang Qinian smiled: "Xiaoshuang, it's useless at all, you think that ordinary people haven't thought about it, people's weight and wing muscles are not suitable for flying like a bird, but the balloon is a one-person solution." ”

"You mean flying in a balloon, that's a good way. It's just too slow. Xiaoshuang said.

"Hydrogen balloons are too dangerous, hot air balloons are good, go back and try them. Wang Qinian muttered.

"What is a hot air balloon?" asked Xiaoshuang, not only Xiaoshuang, but Jessica and Jenny also looked at Wang Qinian.

Wang Qinian said: "It is a balloon that uses the principle of hot air, and I will show it to you when I go back." ”

They returned to Huolin Qiaoton, Xiaoshuang pestered Wang Qinian to see the hot air balloon, Wang Qinian smiled and made a hole lantern, Xiaoshuang saw Wang Qinian light the lamp. The lights really floated. Jessica was also watching from the sidelines, and Xiaoshuang flapped her wings and flew with it, flying for a distance. She opened her mouth to blow the lamp. The lights flickered down. Although some students saw it, they thought it was a teacher who used magic and didn't pay attention to it.

Xiaoshuang holds a Kong Ming lantern. Kong Ming lantern is much more than her, fortunately, it is lighter, Xiao Shuang can hold Kong Ming lantern and fly back: "Wang, this thing is more fun, I went to the mountains and forests." ”

After finishing speaking, he swayed and flew towards the mountains and forests in the distance with the Kong Ming lantern, Wang Qinian shook his head, and Jessica suddenly spoke: "What is the principle of this? Air expansion, you can study it, by the way, Wang, can you study this problem?"

"Yes, the air expands when it is heated, it can be studied, it just so happens that you are not studying the real yàn of peas, that real yàn takes a long time, it is better to start another project to study air thermodynamics. Wang Qinian said casually.

It's not that he doesn't want to study, he's already working on electrochemistry, he doesn't want to attract more attention, there are too many things to study, it's better to let Jessica study it.

"I invite you to join. Jessica's eyes rolled, she knew what Wang Qinian must know, "You, as the main member, by the way, have to pull someone." ”

"Just Jenny, she should also give you a hand, in the research, if you get feedback from heaven and earth, it will be rare for her, it depends on the depth of her understanding. Wang Qinian said that he had basically figured out the essence of the feedback from heaven and earth, to put it bluntly, it was just feedback in the collective unconscious of human beings, but why did this mechanism exist, Wang Qinian was very curious, could magic really be something similar to an illusion, but why it was so, Wang Qinian couldn't figure it out.

"I was going to pull Emma. Jessica said.

Wang Qinian said: "Emma just wants to find her, she is from the magic items management department, I want to discuss the yacht with her, I want her to mobilize students to make samples, she is very suitable for this, I take out the drawings, if the interest is big, I want to make a deal with the school, and exchange this industry for the pass to the Gate of Legends." ”

"Are you on the edge of a legend?" asked Jessica.

"No, I'm at most at the middle level of the Magus, but be prepared first, or it won't be too late if it rains. Wang Qinian said.

"It seems that I have to prepare, although I am a high-level mage, it seems that the magician is only a matter of one or two years, and there are still a series of conditions for the advanced legendary magic array, which is difficult for individuals to meet, especially if they need the help of a legendary mage. Jessica said.

"You are the lady of heaven, and I believe you will succeed. Wang Qinian encouraged.

Wang Qinian explained, on the thermodynamics of the gas to make some preparations, Jessica also put forward her opinions, after discussion, Jessica went to the school to apply for the real yàn room, she did not do it in her house, because her house has been transformed into a genetic real yàn preparation, Wang Qinian did not say that he did it in his house, his real yàn room is also useful, so he went to the school to apply.

Wang Qinian went to the Magic Items Management Department, discussed with Emma about the air yacht, and gave her the drawings, the air yacht is nothing new, and the use of the floating array is not a problem in terms of technology, but there has been no need for it, so it is rare for magicians to do these things.

However, Wang Qinian seized this opportunity this time to carry out this plan with the Sky City as the background to make it look promising, Emma looked at the drawings and said with a smile: "This is not difficult, I will organize students to do it, and strive to complete the three spaceships before the Sky City goes to the sky, and when the Sky City is launched, our spaceship will also be lifted off to give our spaceship a publicity." ”

Wang Qinian nodded: "As long as the luxury airship flies for the time being, the things inside are determined according to the requirements of the customer, and I want to install some magic items in it as a means of defense." ”

"I'll leave this matter to me, just in time to digest the accumulated magic items. Emma laughed, Wang Qinian laughed, Emma has the Su zhì of a profiteer.

After these things were completed, Wang Qinian's paper was almost done, he summarized the electrolysis of water, figured out the composition of water, the ratio of hydrogen and oxygen atoms is two to one, discovered some alchemy elements, and summarized the properties of hydrogen and oxygen, put forward the standard concept of electrolysis and a series of knowledge, the paper "Water under the Action of Electricity" was also completed, and was sent to the editorial office of "Magic", at the same time, the research on the expansion of gas and other aspects was also carried out with Jessica, but problems were encountered at the beginning.

This question is affected by phlogiston, people think that it is a separate element of existence, especially the four internal properties of cold, heat, dry and wet in the old theory of elements, so that Jessica is deeply affected, thinking that heat is also an independent existence, Wang Qinian refuted this view, he believes that temperature and heat are just the external embodiment of the speed of particle movement, and there is no microscopic heat at all.

The two argued, but Jenny was at a loss, she felt that what they said made sense, Teacher Jessica gave an example that when you are close to the stove, you will feel the heat wave, the heat is real, and Wang Qinian explained that it is caused by the movement of air molecules, and use magic to create a thin air area, sure enough, the heat wave is much smaller, there are many similar problems, and finally the two reached a compromise, regardless of whether the heat is stored or not, the temperature is set first.

The two encountered a problem again, one person took the ice water mixture as zero degrees, and the water boiled for 100 degrees, Wang Qinian was simply very thorough, and directly stopped the movement of the particles at zero degrees, and the particles were in a never-ending motion, which was still a hypothesis at the time, although a lot of evidence pointed to it, Jessica thought that using a hypothesis as a basis, and was not rigorous in attitude.

Fortunately, Wang Qinian proved that the two temperature systems are the same, Wang Qinian called his temperature system absolute temperature, and Jessica's temperature as relative temperature, and then it was more smooth.

When they were doing the real yàn, the school opened, Wang Qinian and Jessica also stopped the real yàn, all the teachers and students had a meal in the cafeteria, and the long table was full of turkey, steak, sausage and other food, and Otrando held up a glass, not wine, but a non-alcoholic drink, saying blessings.

After the banquet opened, the sound of knives and forks, Wang Qinian rarely ate in the cafeteria, watching the flowing dishes appear on the table, one by one fantasy species are invisible in it, constantly transmitting all kinds of dishes, most of the students can't see it, especially the freshmen. only saw plates of dishes appear out of thin air, and sighed at the magic of magic, but Wang Qinian could see it.

After the banquet, Wang Qinian returned to his residence, Xiaoshuang did not go there to eat, the food there did not suit her appetite, sitting alone at the dining table, in a daze, Wang Qinian saw her and said, "How are you, are you unhappy?"

She shook her head and said, "I miss the Black Forest a little." ”

Wang Qinian has always been very curious about Xiaoshuang's origins, and he didn't know where she came from, hearing her say this, he said with a smile: "If you want to go back to the Black Forest, you still use the method last time, projection back, after all, this is thousands of miles away from the Black Forest, the strange thing is that Nobi and them don't know why, it seems that the divine power has not increased much." ”

"Wang, I was about to tell you that I felt a great deal of divine power, and there seemed to be a sense of responsibility in my heart, and I had unconsciously used some divine magic, and now someone is praying to you. Xiaoshuang said.

When Wang Qinian heard this, he was stunned, and then looked inward, observing himself and Xiaoshuang from the perspective of the soul, and found that the power of his faith was actually greatly concentrated on Xiaoshuang, and he was only by his side for a while.

What's going on? (To be continued......)
