Returning to Xianyang from Yanmen County, the old men called their son and said something about the hour, then cleaned up and went straight to the morning court.

So much so that during the whole morning court, Zhang Han and others hung their heads, were listless and did not say a word.

They didn't even know what the officials reported and what Ying Zheng said!

Finally, I was over until the morning court was over. I thought I could go back to my house and make up for a good night's sleep, but Ying Zheng stayed to see the hand-crank generator that Xiao Zhengtai said!

Hearing this order, the old guys had to sigh deeply!

All right!

This is really going to kill them!

"You guys are sure...this thing can produce lightning?"

The moment he saw the cycling generator, Ying Zheng immediately frowned and showed an incredible expression.

Other old guys turned around the generator with hand-cranked hands and shook their heads, not optimistic!

In their imagination, electricity should be extremely powerful, and even if it can be artificially made, it must be a giant machine.

The one in front of me is not big, but it looks very simple to construct.

Can this send electricity?

"Father, my son and I have told you that the electricity we want to produce is not lightning, and its power will not be so huge, but a stable and continuous current!"

Ying Feiyu explained again.

This hand-crank generator is a system reward. Although he is not very satisfied, it is much better than not!

At least this can be used to let Ying Zheng and others understand electricity and thus develop electricity!

"Father, look, this is called a wire, which can transmit the power generated by a hand-crank generator!"

"And this is called a light bulb. As long as the electricity is transmitted here, the light bulb will become brighter, illuminating the entire room!"

"And this wheel is the most important part of the entire generator. Just shake the handle and make the wheel rotate, and electricity can be generated!"

Ying Feiyu patiently explained to everyone the structure and function of the hand-crank generator.

"Okay, okay! I know, let's show it quickly!"

Ying Zheng waved his hand and urged him.

"good!"

Ying Feiyu nodded and called on the palace maid to cover all the windows.

In just a moment, the room turned black!

Then he called a little eunuch, asked him to prepare and shake the handle.

"yes!"

The eunuch responded, rolled up his wide sleeves, came to the generator, and slowly shook it.

Everyone also set their eyes on the light bulb.

However, after waiting for a while, the light bulb did not react at all!

"You can't do this, you have to be faster!"

The hand-crank generator was also the first time Ying Feiyu had just exchanged it from the system warehouse.

According to his guess, the light bulb never responded, probably because it was not motivated enough!

"yes!"

The eunuch received the order and immediately accelerated the speed.

Sure enough, the light bulb suddenly emitted a dazzling light.

The old guys were caught off guard and couldn't open their eyes. They quickly covered them with their wide sleeves!

However, in just a moment, the lights went out again!

Next, there is a dim light intermittently!

"This...what's going on?"

Ying Zheng didn't understand why, and pointed to the light bulb that emitted a faint light and asked.

"It should be because the eunuch is not strong enough. After shaking it a few times, it becomes powerless again, resulting in unstable voltage!"

"I see!"

After understanding, Ying Zheng glanced at the eunuch.

"Your Majesty, please spare me, I... I'm really bored!"

The little eunuch thought that he was in trouble, so he quickly knelt down and kowtowed and begged for mercy.

"Okay, get out!"

The light bulb emits a dazzling light, and Ying Zheng's just a little bit of interest was disturbed at this time, and he was in a bad mood.

But it's not too harsh!

"Father, this hand-crank generator is the first time they use, and they don't know how much strength they should use! Besides, they have lived in the palace for a long time and have never done much strength and are not strong enough!"

Ying Feiyu said with a smile.

"If you can light up this thing with just your strength, I can!"

Wang Ben raised his arms and sleeves and recommended himself.

"Then I'll have a good time!"

Ying Feiyu nodded and asked Wang Ben to shake the handle.

"You guys just see!"

Wang Ben is strong and has a strong body, and he has no problem on a long journey, let alone shaking a small handle.

In just a moment, the light bulb lit up again.

"It's bright, it's bright, it's bright again!"

Zhang Han and others cheered in surprise.

With the experience of the last time, the old guys did not look directly at the light bulb, but observed it with their after-light light!

"Oh! The light emitted by this electricity is really bright! Such a small thing is even more dazzling than the light emitted by ten candles! It shines brightly in the room!"

Ying Zheng was full of surprises.

"Yes! Your Majesty, if your imperial study room can use this light to illuminate, and if you stay up late to review memorials, you will be fine without your eyes!"

Zhang Han smiled excitedly.

"It's really not easy to have eyes, but it's a bit too much!"

Just as everyone was full of surprise, Wang Ben's voice interjected in an inappropriate manner.

Immediately afterwards, the light of the light bulb became weaker and weaker, and finally disappeared!

At the same time, Wang Ben also gasped and released the shaking handle, "No, Your Majesty, I really can't shake it anymore. This thing is too hard!"

A hand-crank generator seems simple, but if you want to keep the light bulb illuminating continuously, you have to keep shaking it.

Although Wang Ben had the strength to shake the handle so quickly, his arms were so sore!

"Hmph! Lao Wang, didn't you just swear to let us see it? Why? That's what you let us see?"

Zhang Han exhaled his breath from his nostrils and snorted coldly.

The light bulb that can emit dazzling light is a new thing. They went out before they could see it enough. It was really disappointing. No wonder Your Majesty was unhappy just now!

"Old Zhang, don't stand and talk without a pain in your waist. If you don't believe it, go and try it! I may not even be able to light up the light bulb!"

"Just try it!"

Before becoming the Minister of the Shaofu and the Ministry of Revenue, Zhang Han was also a general. He often led troops to fight and believed that he was in good physical strength.

But after just after I went up and shook it for a while, the light bulb had just emitted a faint light and was defeated.

"That... Your Majesty, I am ashamed. This thing is really exhausting! In just a while, my arm is sore!"

Zhang Han shook his arms back and forth and said with a bitter face.

"Hmph! Lao Zhang, you are not as good as me. At least I let the light bulb light up stably for a while, but you haven't even started!"

With the opportunity to fight back, Wang Ben naturally would not miss it and mocked Zhang Han.

This time, Zhang Han didn't even make a fart.

There is no way, that thing is definitely a physical job, and most people really can't do it!

"Take all the cloth covering the windows away!"

Ying Feiyu ignored the bickering between the two and ordered the palace maid.
Chapter completed!
