"Hehe, that's not true!"

In the "lab", when Li Zexuan heard Xiaoxi swearing there, he couldn't help but chuckle: "If someone threatens you with your life in the future to tell you what I did, Xiaoxi, you must save your life first, young master. These things I make are not as precious as your life! Do you hear that?"

"Master~!"

In Xiaoxi's bright eyes, there was a flash of crystal, and the little girl was really moved.

"Cough cough!"

Li Zexuan couldn't stand Xiaoxi's eyes, he quickly turned his eyes away, coughed and said: "Actually, I'm just doing a small experiment, the purpose is to create a new energy, er, it can't be regarded as new energy, right? This thing already exists in nature."

"Master, what are you talking about? What is new energy? What is nature!"

Xiaoxi's feelings gradually calmed down as Li Zexuan spoke, but she suddenly heard so many new words and was a little confused for a while, so she couldn't help asking.

"Uh, energy, energy is...Xiao Xi, you can understand energy as doing things, ahhh, it's the ability to do things, for example, young master, my martial arts are strong, and I lift hundreds of pounds of stones with one hand. , it’s because I have a lot of energy in my body, and why can firewood boil water and cook rice? It’s because firewood also has energy in it! Do you understand?”

Li Zexuan's brain hurt a little when he heard these questions, but he explained patiently.

"Oh~~! Xiaoxi understands, according to what the young master said, Xiaoxi also has energy in his body, because Xiaoxi can cook and take care of the young master!"

Xiaoxi propped her chin up, thought about it, and suddenly smiled.

"Hehe~! You're right!"

Li Zexuan couldn't help but feel a little happy when he saw the little girl's bright and moving smile. He nodded and continued:

"As for the natural world, the natural world is the big environment in which we live, it includes the sky, the earth, people, plants and animals, etc. The reason why I just said that this kind of energy already exists in nature is because, young master, I The thing created is the same energy as lightning!"

"Wow~~! The young master is so powerful that he can make thunderbolts! Isn't that young master the thunder god in the sky?"

When Xiao Xi heard the description of her young master, she suddenly had heartbreak in her eyes and exclaimed in surprise.

"Cough cough cough~~!"

Li Zexuan almost spit out a mouthful of old blood. He is so handsome and handsome, how could he become Lei Zhenzi's birdman with two wings?

"Cough, Xiaoxi, I just said that this thing I made is the energy of the same attribute as lightning, and I didn't say that this is lightning! This is much weaker than the energy of lightning, I call it electricity!"

"Oh~~!"

When Xiaoxi heard the words, she nodded as if she understood, and then she smiled: "Even so, the young master is very powerful~~! Xiaoxi has never heard of anyone who can make lightning!"

Cough, of course you haven't heard of it. If you've heard of it, then there must be another transmigrator in this world. Li Zexuan couldn't help muttering in his heart.

"Then... The young master, you just said that the electricity you created is a kind of energy, but what can this energy be used for?"

Xiaoxi looked at the strangely shaped clay pots on the table and asked curiously.

"Haha! Good question!"

Li Zexuan glanced at Xiaoxi with admiration, then smiled:

"Electricity has many uses. It can generate heat, boil water, and cook rice. It can also replace candles and light up the whole house at night. It can also make machines move. If electricity is used in carriages Come on, in the future, maybe the carriage doesn't need a horse, it can move on its own, and it can run faster than a horse!"

"Wow~! Young master, is this electricity really so magical?"

"Of course, but to achieve these functions, you must build some corresponding tools. For example, if you want to use electricity to boil water, you must build a tool for boiling water, and then turn on electricity to boil water; if you want to use electricity To illuminate, you have to build a lamp, not a lamp that burns oil, but a lamp that consumes electricity.”

Li Zexuan explained patiently.

"Oh~! Xiaoxi understands! Just like we usually use firewood to boil water, we need to make a pot first, right? Master?"

Xiaoxi listened very seriously. In order to keep up with her young master's thinking, her mind was also spinning very fast. She laughed as soon as Li Zexuan's voice fell for a while.

"Mmmm, clever! That's it!"

Li Zexuan nodded.

"Hee hee~! That young master, we don't have tools to boil water or lamps that consume electricity. What's the use of the electricity you built?"

Xiaoxi first smiled happily, and then she asked with some doubts.

"Hey, you don't have tools, you can make tools! Xiaoxi, wait a minute, I'll show you a trick tonight, young master!"

A flash of light flashed in Li Zexuan's mind, and an idea suddenly came to his mind. After he finished speaking, he ignored Xiaoxi's doubts and went straight out.

"Hey, young master, where are you going?"

Xiaoxi anxiously wanted to go out, but she couldn't keep up with Li Zexuan's footsteps, so she had to sit down by herself and continue to wait.

About a quarter of an hour later, Li Zexuan came back with a bamboo stick.

Seeing that he had taken the long sword, "swish" a few swords, and there were a few slender bamboo threads on the table, Li Zexuan stepped forward and picked one.

A bamboo thread of even thickness was placed on the flame of the candle and began to be roasted carefully. After a while, the blue bamboo thread turned into black bamboo charcoal. Li Zexuan used an iron wire to wrap around the middle point of the bamboo thread, and then he put The other end of the wire was handed to Xiao Xi and said:

"Come on, Xiaoxi, take it, and soon you can see the lighting effect of electricity!"

"Uh-huh!"

"Remember to stay away, don't let your hair touch the bamboo silk!"

"Okay, young master!"

"Look! It's only for that moment!"

The experiment that Li Zexuan is going to do is the prototype of the light bulb.

In 1854, Henri Goebbels used a carbonized bamboo thread, which was energized and glowed under a vacuum glass bottle. His invention was later seen to be the first practical incandescent lamp. The light bulb he tested at that time could last for 400 hours, but unfortunately he did not apply for a design patent in time.

Li Zexuan skillfully connected twelve batteries in series, and then carefully connected the positive and negative poles of the entire large battery to both ends of the carbonized bamboo wire. The bright light easily drowns out the flames of indoor candles.

The bright "light" shone on Xiaoxi's delicate cheeks, as well as her snow-white and smooth Su (chest) with a few ravines faintly appearing, coupled with her slightly open mouth and surprised expression, The originally beautiful Xiaoxi now looks even more glamorous under the "spotlight", and Li Zexuan was fascinated by it for a while.

"Ah~! What a beautiful light! Young master, this light is ten times brighter than a candle, but unfortunately it only lasts for a while!"

Xiaoxi exclaimed excitedly, what she experienced tonight has completely subverted her cognition, and she is afraid that she will never forget it for the rest of her life.

Cough, why is this little girl more and more attractive? Almost obsessed!

Li Zexuan, whose thoughts were interrupted by Xiaoxi's exclamation, couldn't help shaking his head, and when he heard Xiaoxi's words, he smiled in his heart: "This bamboo thread is not placed in a vacuum, of course it can only be lit. For a while! But maybe I can make some light bulbs to play with later!"

"Xiao Xi, do you like it?"

"Hmm, I like it!"

"Then the young master will make you a lamp that can always emit such a bright light!"

"Yeah! Young master is so nice!"
