When Huang Chengyan shouted, Lu Bu immediately summoned them in.

Soon, Huang Chengyan's two disciples walked into the study with a set of equipment.

Several eunuchs and palace maids who were serving in the study were curiously looking at the set of equipment held by the two disciples.

I saw that this set of equipment was very strange. They had never seen such strange things like ancient Chinese. There were many wires connected on it, and I don’t know what it was for.

When Emperor Lu Bu looked at him again, he came to the equipment excitedly and said to Huang Chengyan: "Father-in-law, please operate quickly and let me see!"

Huang Chengyan smiled and said, "Don't worry, don't worry, I have experimented a lot, just take a look!"

As he said that, Huang Chengyan first took a narrow back end from a disciple, and the front section was swollen, like a ball but irregular glassware.

Well, if you are seen by modern people, you can probably guess that this should be a light bulb.

The reason why I use it two words is that the light bulb made by Huang Chengyan is much more crudely made than modern light bulbs, and it doesn't look exquisite enough.

However, there is not much difference in appearance.

At this time, Huang Chengyan touched the switch with a smile, and said in a lewd manner: "The following is the time to witness the miracle, Dangdangdang!"

Hearing Huang Chengyan's words, Lu Bu couldn't help but feel black.

Huo, this old man learned to talk nonsense with Huang Yueying, and he learned bad things!

Lu Bu didn't think about it either. Who did Huang Yueying learn these words? Didn't he learn them from him?

The next moment, Huang Chengyan pressed the switch, and the light bulb immediately emitted a dazzling light, which immediately caused the eunuchs and palace maids present to exclaim.

This, this is really incredible!

It's really amazing!

How could such a big thing emit such a bright light?

And there was no smoke or ignition, how did he light up?

Could it be that the father-in-law can do magic?

Seeing the brightness of the light bulb, Lu Bu nodded in satisfaction.

Then Lu Bu couldn't help asking Huang Chengyan: "Father-in-law, I wonder if you have done an experiment? How long can this light bulb be used?"

Hearing Lu Bu's inquiry, Huang Chengyan laughed and said, "Your Majesty, don't worry. We have all done experiments and it's still on, and there's no problem for three days and three nights."

Well, if it can reach this level, it can be put into use.

Huang Chengyan continued: "Your Majesty, we have prepared some battery packs. In the past few days, the palace queen and a few empresses can use this light bulb."

"good!"

Finally, the light bulb is made. At night, don’t light that damn candle.

The light of the candle is incomparable to the light bulb, and it also has a pungent smell.

Although the candles used in the palace are all high-quality, even the best candles will inevitably smell.

But this light bulb is different. Not to mention brightness, it will not produce any odor.

...

Huang Chengyan said excitedly: "I believe that light bulbs will become popular in Nanjing soon, but I'm afraid only those rich businessmen can afford it? Ordinary people may still find it difficult to use light bulbs!"

Due to the problem of craftsmanship, the cost of a light bulb is not cheap at present. Of course, if you just buy a light bulb, I believe that even ordinary people can afford it.

However, as a power supply battery pack, it is very expensive to build because the electrolyte and other substances inside are still quite expensive to manufacture now.

This is also impossible. The technological level of Dahuachao can be said to be a rapid improvement in its technological level, but there are still too few scientific researchers, which directly leads to the production and R&D level and manufacturing capabilities that are far from keeping up.

At home, even if you can buy a battery pack by selling iron, it may be difficult for ordinary people to afford the cost of replacing the electrolyte inside.

In Huang Chengyan's view, there is still a long way to go to light bulbs to enter the homes of thousands of households.

However, Lu Bu didn't think so.

Well, if it really becomes popularized throughout Dahua, it is probably impossible to do it without ten or eight years of effort, and it will even take longer.

But this time is definitely far shorter than Huang Chengyan's estimated time.

Because now, Dahua has achieved all this, not from scratch, but needs to cross the river by feeling the stones.

Instead, they have practical experience to learn from, which can help them avoid many detours and save a lot of time.

Thinking of this, Lu Bu couldn't help but say to Huang Chengyan: "Father-in-law, it is not as difficult as you think to let the light bulb enter the homes of thousands of households! I think you can study the power station next."

Lu Bu had never mentioned the concept of a power station before, so after Huang Chengyan heard Lu Bu's words, he couldn't help but look confused.

"Your Majesty, I don't know what the power station you are talking about is for and what is its purpose?"

Lu Bu smiled and said, "The power station is probably like a battery, but it is just a very large battery that can supply thousands or even hundreds of thousands of households."

"I have abundant water resources in Dahua, so I can consider using water to generate electricity. As long as I can build a water power station, it will be not far from all the people in Dahua that can use electricity."

Hearing this, Huang Chengyan's eyes suddenly lit up.

I quickly asked Lu Bu what the principle of the power station is, how to structure it, and other details.

And Lu Bu had actually been prepared for this.

Lu Bu handed Huang Chengyan the information he had prepared in advance. After Huang Chengyan took it, he couldn't wait to open it and soon became addicted to it.

Seeing this, Lu Bu couldn't help but smile.

According to Lu Bu’s understanding of Huang Chengyan, his father-in-law will definitely leave with this information soon.

As long as you discover a project you are interested in, your father-in-law will soon reach the point of forgetting to eat and sleep.

But this time, Lu Bu obviously miscalculated.

Because this time, Huang Chengyan quickly combined the information that Lu Bu gave him.

Then he said to Lu Bu dissatisfiedly: "Master, do you have no indication of our achievements?"

When Lu Bu heard Huang Chengyan’s inquiry, he couldn’t help but sweat. How could he not express it? But can this express still be needed?

Lu Bu couldn't help but say, "Father-in-law, don't worry. Everyone in the project team has generous rewards, and no one is missing."

Huang Chengyan said unhappily: "Is there only the reward?"

Ah? What else do you want besides the reward?

Lu Bu couldn't help asking: "Father-in-law, what else do you want? As long as you ask, I will satisfy you!"

Huang Chengyan smiled and said, "The rest is not needed anymore. They are just needed, the emperor, you personally treat them to a meal!"
