The place where Leeds took the girls into was indeed a "hotel", but it was a "hotel" that had to be defined by two words in front of it - this facility was still very simple in this era, not only all kinds of strange things in later generations had not yet appeared, but even the interior decoration was quite poor, except for candles and leather whips, only all kinds of strange clothes remained.

To be honest, Liz is very interested in having her beautiful lover play a game of changing clothes in front of her, and in the case of Sakiya, the style of her maid dress will be changed every two or three days, just to cater to his preferences...... It's just that under the strong resistance of Zhang Jing and Murong Jiu, who are still thin-skinned, the "dress-changing game" still can't be launched after all.

Well, the evil plan cannot be carried out, and the only thing that can be advanced is the righteous plan.

"The changes in the previous world were all born around the 'steam engine'," and "after dawn, Leeds came out of the hotel to be a good tour guide and a good enlightenment teacher again," and the changes in this world were born around two other things. ”

"First, for the 'internal combustion engine', the steam engine uses fuel to heat water and uses water vapor to drive the piston to move, and it burns fuel directly in the machine and uses gas to push the piston to move, which is more efficient," looking at the passing car," ...... This thing is an example of a use case. ”

"............" Wang Yuanji and the three were not surprised, but just carefully observed the car.

I've seen 'cars' and 'airplanes' many times when watching TV in the Overworld, but I didn't know the names and rationale of its core components until now...... Hmm~ I'll go to the bookstore and buy a few books about 'internal combustion engines', right? The reason has already been mentioned in the previous world, and there is no need for Leeds to repeat it once.

"The second is a 'generator' and an 'electric motor', the generator can convert fuel into electricity that is more convenient to transmit and has special properties, and the electric motor can convert electricity into power," he said, looking at the TV in the window of a roadside shop...... This is an example of use, but please don't think of what we synthesize as equivalent. ”

"............" Wang Yuanji and the three continued to remain silent, looking at the TV intently.

Not to mention the black and white pictures, the graphics are too delicate to be acceptable to them who are used to the TV sets in the Overworld...... Oh, by the way, this thing isn't a perpetual motion machine yet, it consumes electricity.

"Well, that's it, and then it's time to go shopping-"

"Huh?! That's gone? Zhang Jing asked in surprise.

"So this is the 'core'~~" If you talk about all the messy things, it will in turn seem that the really important things are not so important, "Also, when I taught you in the previous world, didn't you and the ninth sister have a 'you're so annoying' attitude?" Why do you still dislike me for talking less. ”

"Who dislikes to say less, stinky beauty!" Aside from Liz, he stepped forward quickly.

It's just tsundere, don't care about attitude.

In fact, after Leeds finished the class, they secretly did various experiments, such as disassembling the telescope and using the lens inside to verify Leeds's lens theory, or inserting a branch diagonally into a glass bottle filled with water to observe and study the refraction theory in all directions...... They may not be as keen on exploring knowledge as Wang Yuanji, but the results of the experiment still make them look forward to Leeds' next science popularization class.

"Haha, it's actually my literacy level is coming to an end," Liz didn't care, and explained with a smile, "Just like now, if you ask me to explain how the 'electricity' of a television is converted into image and sound, I can't give an accurate answer unless you ask me to look it up right away...... And this is not fundamentally different from looking up the relevant information on your own. "The difference is only the difference in comprehension caused by the difference in basic literacy, but this can be completely compensated for by the time of reading comprehension.

"So we'll be able to catch up with you soon?" Murong Jiu asked suddenly.

"About the next world, you know what the [information age] is, and after learning to use the [Internet], it will be completely synchronized with me." Although Leeds still has a lot of bits and pieces of common sense, magic, vindictiveness, gods and demons, but the farthest is still 'technology'.

“…… Hmph~" Murong Jiumei snorted, but her steps suddenly became brisk, and she walked forward with Zhang Jing.

She was quite happy that the days she had been teased by Liz would come to an end in the near future...... And after that, maybe she can tease others with a similar mentality?

Murong Jiu's lost self-confidence is about to return~~

"Ahh

“…… Lord Leeds," Wang Yuanji, who was left behind, asked softly, "...... you bothered to let us keep up with you?"

"Asking this now?" Liz said strangely, "Of course, it's to let you play the game better with me~~"

"Play the game...... Is it? Even if there was such a speculation for a long time, but when he actually heard the result, Wang Yuanji still felt very grotesque.

"Let's put it this way, when we see a person suddenly become a behemoth after being injected with a biochemical virus, my head and I will complain, 'What about the law of conservation of mass!' , and you're probably just going to say, 'Monster! ’…… Although I don't expect you to be completely in sync with my way of thinking~" This will also become very boring, "But at the very least, you have to understand what I complain about......"

“…… I see," this example is very effective, at least Wang Yuanji doesn't know what the Law of Conservation of Mass is now, "I will do my best to respond to your expectations, Lord Leeds." ”

"Haha, don't be too serious, slowly expand your knowledge in the form of a tour, and you will soon be able to achieve the expected goal," Liz suddenly reached out and pulled Wang Yuanji and Saki Ye, ran forward quickly, and crossed Zhang Jing and the others, "Hey, you two, hurry up and come along, I'll take you on the tram." ”

"Cut, stinky foreign devils, a group of beautiful girls have been arched by him." Ah Xing, who was squatting on the side of the street with his friend Fat Tsai Cong, watched a foreign man run onto the tram with four unbeautiful women, and said with a lot of unhappiness.

"It's really unreasonable for a man like me who has a promising future but doesn't have a woman to care about!" Just as he was muttering something, a cigarette butt was thrown on the ground, and Ah Xing hurriedly picked it up and took two puffs.

"............" a certain gold-rimmed glasses looked at him.

"What are you looking at, four-eyed boy, believe it or not, my glasses will blow you up!"

“！” The gold wire glasses hurriedly picked up the leather bag and rushed to the tram, but,

"Hit the streets, dead beggar!" Anyway, he's still grimacing there.

"There's a kind of you getting off!"

On this day, the hero is still squatting on the side of the street. (To be continued.) )
