In those times when the material was relatively weak but was on the rise, the children really found a lot of solutions by relying on their own hands and brains, as well as the inheritance of generations of children.

For example, spinning tops. For example, rolling hoops, such as toy bows and arrows, such as paper kites, such as mud fights...... For example, the current crooked trick of taking out the electrical lighter from the used lighter, or taking the caps of beer bottles from my father, and smashing the caps with stones to flatten and flatten them, there is a similar and interesting way to play like playing with pieces of paper......

Children's wisdom and hands-on ability are always endless.

Wu Zhi thought of all the various things he used to spend his childhood at that time, and he thought it was funny. At that time, the things I played with were so naïve, and in the process of playing, there were countless embarrassing things that I felt very embarrassed when I grew up, but at that time, I was just happy to do it, I just thought it was fun, and I felt energetic......

It's called childhood.

No childhood is complete without such silly and funny children.

At that time, it was okay to have no money, but it was impossible to do without partners. As long as you find a partner, the colors of childhood can naturally become colorful, and you can leave countless wonderful moments and laughter.

Wu Zhi was stubborn at this time, but Fang Wen and a few people were sorry because they destroyed the fire, Wu Zhi laughed, walked over, grabbed Fang Wen's hand, and said with a provocative smile:

"Fang Wen, do you dare to try the taste of being eaten by ants?" —note 1

"Ant...... Ga? ”

"No, it's bah, that's it, it's the meaning of the bite......"

"What do you want to do?"

"Just ask if you're afraid!"

"Afraid, no, not afraid!" Wu Zhi always doesn't play cards according to the routine, and Fang Wen is really a little afraid.

"Don't be afraid, you can't die."

"What? Ahh

As he spoke, Wu Zhi had already pressed the switch and put the broken wire skin on the back of Fang Wen's hand for an electric shock.

Fang Wen was so shocked that his hand immediately retracted, and he took a few steps back one after another, far away from Wu Zhi.

"What's that?"

"That's it!" Wu Zhi shook the small piezoelectric lighter in the air.

"What's going on with this thing, why do I feel like I've been bitten by a snake......"

"Is it so exaggerated, it's just like being snuck by ants......"

"It's not, it's like being bitten by a snake......"

"You're wrong, do you want to try again......"

"I don't want it! Don't come near me! Fang Wen hurriedly hid behind Fang Qiong.

"Li Zhong, do you want to give it a try?" Wu Zhi snapped and aimed the lighter at Li Zhong.

"No, I don't want it either!" Li Zhong also resisted again and again.

"I'm coming!"

It was Fang Qiong who was the first to jump out. She heard Wu Zhi and Fang Wen say that one said that it was like being bitten by ants, and the other said that it was like being bitten by a snake, so she was curious, didn't she say it was a toy, how could she be so scared that even a big man was afraid?

I don't believe it!

"Reach out and roll up your sleeves!" Wu Zhi ordered.

"Come on, who's afraid of whom!" Fang Qiong did so, and as soon as she stretched out her left hand, Wu Zhi lit her wrist with electricity, and Fang Qiong's hand subconsciously hurriedly pulled back and shouted:

"Oops!"

She's not doing much better than smelling......

"What's going on?" Fang Qiong was surprised.

"It's called an electric shock."

"Electric shock?"

"Yes, I said that this is a piezoelectric lighter device, as long as you press the button, you can instantly generate voltage, forming an electric spark, being hit by an electric spark is called an electric shock, you only know the importance of fire, but you don't know the importance of electricity......"

"Electricity?"

"Yes. It doesn't matter if you don't understand it yet, sooner or later, we will all enter the electric age together, and at that time, you will know that for ordinary residents, the four most important energy sources are, water, electricity, oil, gas, ......"

"What about the fire? Without fire, aren't we going to eat raw things like animals? Fang Wen was very concerned about the issue of "eating".

"Don't worry! At that point, it's not that there is no fire, it's that the way of making a fire becomes too simple and too easy......"

"Like a lighter?" Golden Lotus Road.

"Yes. For example, there is gas. ”

"Gas? You mean air? Fang Qiong said.

"It's not. It's natural gas. ”

"Natural gas?" Li Zhongdao.

"That's right. Natural gas in the narrow sense usually refers to things that are used to make fires in people's homes, while natural gas in the broad sense includes more gases that occur naturally in nature and are ideal energy sources for human beings......"

"And what is that oil?" Fang Wen asked.

"Oil."

"Cooking oil?"

"No, it's a stone of stones. Shen Kuo, do you know? According to the current time, he has only been dead for about 20 years, and he is a well-known and influential figure in later generations. It was he who first came up with the name 'oil' when he discovered a kind of 'lipid water' in Gaonu County, which is a product of mixing oil with spring water, and the locals dipped the oil from pheasant tails and collected it in clay pots for fire or lighting. And Shen Kuo also used it to make a kind of high-quality ink, named 'Yanchuan Stone Liquid', which was greatly praised and loved by Xiao Su's bachelor......"

"So oil is used to make ink?"

"No, that's right now. In the next 1,000 years, oil will be an important source of energy, and if every household does not have such a thing, the tin can at home will not be able to run, and the planes flying in the sky will fall to the ground in minutes......

"What is a tin can?" Sister-in-law Gu asked.

"It's a car."

"Sedan?"

"Yes. Here you call the tool used to fill the façade when traveling, commuting and getting married as a sedan chair, and we have followed this habit and tradition, so it is called a sedan. ”

"How many sedan drivers do you need to carry a car? Is it so enjoyable to have eight sedan chairs? Li Zhong also called and asked excitedly.

"Eight sedan chairs?" Wu Zhi glared: "Just kidding." What is this, any car is much more enjoyable than the emperor's sixteen dragons, not to mention how many sedan chair drivers you need, just drive it yourself. ”

"Drive it yourself?" Everyone was puzzled. Just think about the sedan chair, someone has to carry it if someone sits, otherwise, how can the sedan chair run.

"Yes. Open it yourself. A sedan has four wheels, you can think of those four wheels as four sedan drivers, a sedan can generally sit four to five people, as long as one of them is the driver's duty, take the steering wheel, start the engine, the wheels turn, the car can run......"

"Ah, I see, I see, you mean, it's like an ox cart, there are wheels, right, we just need to hold the handle, push hard, and the wheels can turn, and when the wheels move, the ox cart can also move, right...... But in the case of cars, who is the one who pushes the wheels around? ”
