"Senior Sister Xingyin, why are you here?" When Luo Yunjin heard this, he immediately jumped up from the stool and ran away to the ground.

"Yesterday, I worked harder, and I refined the copper wire that Childe needed. It was not early in the morning, and I thought about the use of this copper wire, so I sent it. Xing Yin glanced at Mu Heng with a smile, and in a blink of an eye, he was attracted by the prototype of the generator made by Mu Heng.

"I'm glad to have a girl." Mu Heng sincerely thanked that the wire was refined so quickly, so the process of the generator could be accelerated.

Xingyin didn't answer Mu Heng's words, but looked around the generator. A shelf made of bamboo poles, in which two magnets are placed, and a bamboo pole with a bamboo basket runs through the center of the two magnets, which has a very strange shape and combination.

However, Xingyin, who has been refining weapons for a long time, did not ask Mu Heng questions, and he has a good habit of science students only looking at it and not talking about it. With big watery eyes, he stared at Mu Heng's every move, wanting to see what he could come up with.

Mu Heng took over the wire, quickly brushed with tung oil, and then wrapped it with cotton thread to make an original version of the "wire".

Two short copper wires were cut off as wires for the current everywhere, and the others were intended to be used as winding coils. When the tung oil is about to dry, the longest wire is wound around the bamboo basket and made into a rotor to form a coil that can cut the magnetic field.

"Senior sister, bring the rest of the tung oil." Mu Heng wound the coil and instructed Luo Yunjin behind him.

"Here it is, senior brother." Luo Yunjin happily helped Mu Heng run errands, handing the fairy sword for a while, and sending tung oil for a while.

Pour all the remaining tung oil on the coil and add a layer of tung oil to the bent wire part for better insulation.

In fact, it doesn't matter if there is a short circuit, at most the number of coils decreases, and the current produced decreases, which does not have much impact on the result. It's just that since you are doing it, try to do it as well as possible, and don't waste your mental strength.

Fix the rotor coil to a rough version of the wrinkled bearing, put on the prepared brushes and commutators, and finally install a crank handle, similar to a tractor crank, and a simple DC generator is done.

"That's it!" Mu Heng withdrew his hand, put it in his waist, and looked at the primitive generator in front of him, revealing the joy of success.

"That's it?" Xing Yin looked at this thing that he didn't know how to describe, without the slightest fluctuation of aura, and he didn't understand what it was for.

I was inevitably a little disappointed in my heart, and I stayed up all night to help refine the copper wire, but Mu Heng made something that I didn't know what it was.

"Senior brother, what is this?" Luo Yunjin looked at the humble bamboo frame and asked curiously. As a loyal fan of Mu Heng, she has witnessed all kinds of miracles created by Mu Heng, and absolutely believes that what her senior brother has made is definitely not simple, but she can't understand it.

"It's called a generator, and it's used to generate electricity." Mu Heng pointed to the generator and introduced.

"Power generation? What is electricity? Xingyin had never heard this word, and felt that Mu Heng was making it up. However, thinking of Mu Heng in front of him, but he had obtained the Taiyin True Water in the Wuyin Heavenly Mountain, he should not be a person who spoke lightly.

"You don't know electricity?" Mu Heng realized that there seemed to be no such word in this world. After thinking about it carefully, I quickly understood. There has never been artificial power generation in this world, and no one has studied the thunder, and it has been found that there is also electricity in the thunder, and it is normal to have no "electricity" word.

Luo Yunjin and Xing Yin shook their heads in confusion. Mu Heng didn't plan to continue to explain to them, but just beckoned to Luo Yunjin and motioned for her to operate the generator.

"Senior brother, what should I do?" Luo Yunjin stood next to the generator and listened to Mu Heng's command.

"Grab that crank and swing it in any direction." Mu Heng thought a little nausea in his heart, the beauty shook the tractor, and the spicy eyes were simple.

"Is that so?" Luo Yunjin grabbed one end of the crank with both hands and shook it around the axis.

"yes, faster." Mu Heng looked at Luo Yunjin's posture of leaning over and shaking the tractor, his heart blossomed, and he kept urging.

"Senior brother, this thing doesn't look strong, why is it so hard to shake it?" Luo Yunjin was very puzzled why the bamboo poles and copper wires, which were obviously very light, were so laborious to shake.

Can it be effortless, this is to generate electricity, and the resistance to the coil is great.

Mu Heng used two pairs of chopsticks to pick up the two wires left outside and put them close to each other.

Xingyin has been observing, and although she has a lot of thoughts and questions in her heart, she doesn't ask too much, she just watches. Now seeing Luo Yunjin shaking vigorously according to Mu Heng's instructions, he couldn't help but be curious.

Looking at Mu Heng again, holding the two threads with chopsticks, he looked nervous, and wondered in his heart: Could it be that the mystery is in his hands?

The ends of the wires collide, and sparkling sparks are glittered from the copper wires, emitting a sound unique to electric current.

"It worked." Mu Heng quickly separated the two threads so as not to be burned.

"Hey, why are there sparks on the copper wire?" Xing Yin was also startled by the sudden sparks, and quickly approached Mu Heng, staring at the two threads in his hand, trying to see what was strange.

"Yes, senior brother, how can you risk sparks?" Luo Yunjin, who stopped, was already covered with dense sweat on his forehead, and asked Xingyin.

"It's electricity, and it's on fire because it's short-circuited." Mu Heng briefly summarized.

"Oh!" Luo Yunjin should be harmonious.

"Senior Sister Yunjin, do you understand?" Xing Yin looked at Luo Yunjin in surprise, wondering why this girl suddenly became smarter.

"I don't understand." Luo Yunjin replied as a matter of course.

"I don't understand you, what?" Xingyin was about to be defeated by her, it turned out that she had too high expectations, and this was still the cute girl.

"Anyway, I don't understand, no, what else." Luo Yunjin replied with a puffed cheek.

“........”

Xingyin, who was originally unclear, listened to Mu Heng's explanation, and more question marks popped up on his head, what are you talking about?

Puzzled, Xing Yin looked at Mu Heng, and then at the thing called "generator" behind him, is it because of "power generation"?

"Let's not be busy explaining the principle first, junior sister will go get a bowl of water first." Mu Heng didn't have time to say more, he just wanted to try as soon as possible to see if he could solve the Taiyin True Water.

"Brother Haole." Luo Yunjin ran away with a cigarette, and ran back with another cigarette, with an extra bowl of water in his hand.

"Immeasurable Tianzun, you must succeed." Mu Heng muttered in his mouth, and then commanded Luo Yunjin to cooperate with him to start the electrolyzed water experiment.

Insert two wire ports into the water in the water, and under the action of electrolyzed water, begin to bubble slowly. As Luo Yunjin's speed increased, the frequency of bubbling became faster.

Combined with the principle of hydrogen produced by the negative electrode, Mu Heng released a little fire spiritual power from between his fingers to form a flame, trying to ignite the gas coming out of the negative electrode.

The current generated by the "bang" generator is not small, so the amount of hydrogen produced is also large enough, and the ignited hydrogen makes an air explosion sound.

"Ahh Xingyin's cry came along with the sound of an air explosion, attracting the attention of Mu Heng and Luo Yunjin.

"Miss Koyin, what's wrong with you?" Mu Heng's scream startled Mu Heng, and he didn't know what was wrong with her, so he hurriedly asked.

Luo Yunjin stopped what he was doing, ran over, and asked, "Senior Sister Xingyin, did you feel a palpitation just now?" ”

"Well, it was when I sensed this palpitation that I couldn't help but scream and make Childe smile." Xingyin said hello to Mu Heng embarrassedly.

"It's strange, how can cultivators like us suddenly have heart palpitations for no reason?" Luo Yunjin was puzzled.

"Maybe something big is going to happen!" Xingyin didn't know the reason, but he sensed that at that moment just now, the heavens and the earth seemed to have changed a little.

Hearing the conversation between the two of them, Mu Heng felt a sigh in his heart, and then surged with infinite joy. When she first got the Taiyin True Water, Lu Siqi's reaction was similar to that of the two of them, did it really happen?

It should be that the amount of hydrogen is too small, and it can only form a little water mist, which cannot accumulate into water droplets.

Before the start of the second experiment, Mu Heng selected a relatively thick bamboo and made two bamboo tubes, which were used to hold hydrogen gas, so that it could produce enough water after combustion. The test bench was replaced with a tank filled with water.

"That's it. Senior sister, if you work hard, let's do it again. Mu Heng took a bamboo tube filled with water and buckled it upside down in the water, and placed the cathode that produces hydrogen at the mouth of the bamboo tube, so that the hydrogen produced floats up due to its low density, and the water in the bamboo tube is discharged and automatically loaded into the bamboo tube.

In addition, because it is inverted in water, it has a certain pressure, and it can also play a role in compressing hydrogen and increasing storage capacity.

The "Zizizi" electric current electrolyzed water emitted a familiar sound of industrialization, and Mu Heng had the illusion of returning to the twentieth century.

In less than half an hour, the bamboo tube could no longer hold more gas, and the spilled gas floated upward along the outer wall of the bamboo tube. When Mu Heng saw this phenomenon, he knew that it was full, so he casually signaled Luo Yunjin to stop.

"Hey, I'm tired." Luo Yunjin shouted that he was tired, but his face was very happy.

Mu Heng slowly took the bamboo tube out of the water, maintaining its original posture and not letting the hydrogen in it escape. Then he carefully lit a flame on his finger and used it to ignite the hydrogen.

Mu Heng's appearance of walking on thin ice also attracted the attention of Xingyin and Luo Yunjin, and they all watched the movements in Mu Heng's hands attentively.

"Senior sister, Miss Xingyin, you should pay attention to protect your face." While Mu Heng was concentrating on the operation, he didn't forget to remind her that the two of them might explode if the hydrogen gas was ignited.

"Why do you have to protect your face, this thing is still in danger?" Xing Yin never understood what Mu Heng wanted, but even if this little gadget in his hand was a little dangerous, for her, a monk of the Liuhe Realm, it was just an ordinary product, and it was absolutely impossible to hurt her.
