Chapter 397 How Did He Do It?

After subduing Wu Yunwan, Lu Chen stopped going to her room every night. He was busy playing grassland riding games with Xiao Wenyao and Yelu Nanyan these days.

To be honest, Lu Chen almost wanted to give up on letting Yelu Nanyan or Xiao Wenyao conceive their children. After trying for so long, their stomachs showed no reaction at all.

Lu Chen was wondering if he had become a pseudo-celestial being, so the difficulty of getting pregnant had increased again. Chu Yuqin was able to get pregnant in one go, but why couldn't other women, and Wang Qingci, a stubborn person who didn't want to get pregnant, was captured. However, Yelu Nanyan and Xiao Wenyao, who were the most cooperative, could not.

Lu Chen even planned to let Mu Zixuan and the others try again. Although Mu Zixuan, Zhou Youyou, and Zhou Xiaoxiao have all become warriors, their levels are still relatively low, and they are still in the stage where it is easier to get pregnant. If all three of them are pregnant, , then it has nothing to do with yourself.

If the three of them are not pregnant, it proves that entering the pseudo-celestial realm has indeed made it much more difficult for him to conceive a child. If he wants to have children in the future, he will have to spend more effort.

After a period of verification, neither Mu Zixuan nor Da Zhou Xiao Zhou was pregnant. Lu Chen basically clarified the reason. Sure enough, it was not the problem of Yelu Nanyan and Xiao Wenyao, but because he had broken through to the realm of pseudo-celestial beings, so It becomes more difficult for them to carry children.

Lu Chen didn't have a good solution for the realm's restriction on births. Finally, Lu Chen decided to ask the system to see if it had any good solutions.

In the evening, Beiwang Mansion.

Today, the entire Beiwang Mansion was quite busy. Lu Chen stood in Fengyun Courtyard and watched the servants going about their business.

At this moment, except for Wu Yunwan and Murong Xueer, Lu Chen's wives and concubines in the inner courtyard were basically gathered in Fengyun Courtyard.

Today is a special day, a day of electricity.

Lu Chen and the others have already developed light bulbs and set up circuits. There has been a lot of movement in the palace these days, and craftsmen are busy setting up wires every day.

Building electric wires was a big project. There were no rubber or plastics in this era. Although Lu Chen had obtained the drawings of the gasoline refining process, there were no conditions for the development of the petroleum industry in the current Northland.

Lu Chen actually set up a resource exploration department to let them explore for resources such as oil and coal.

It's just that what that department has discovered now is basically coal mines, or iron ore and copper resources. It's still difficult to find oil.

To find oil, you have to drill, but drilling is difficult. In the final analysis, there is no such condition.

Without rubber and plastic, we have to find a way to replace the insulator with something else. Under the current conditions, the best insulators are glass and ceramics.

For the sake of beauty, Lu Chen finally chose ceramic tubes. During this period, the ceramics workshop in Beiwang Mansion worked overtime almost every day to make ceramic tubes, just to lay circuits for Beiwang Mansion.

Originally, it would take half a day to lay the ceramic pipes, but Lu Chen saw that there was not much work left, so he worked overtime tonight to let the craftsmen finish it. He couldn't wait to bring Beiwang Mansion into the electrical age.

I use candles every night. Not only do they have a dim light, but they also have some smell.

As a time traveler, Lu Chen couldn't stand the days of lighting with candles.

Lu Chen stood in the yard and watched, while his wives and concubines gathered around the craftsmen outside with great curiosity, watching them check the circuits and install the light bulbs.

They had already heard Lu Chen talk about generators and lights while they were eating. At that time, they felt very incredible. This was the first time they had heard that electricity could be tied up and used.

After Lu Chen glanced at the busy crowd, he said to the system in his heart: "System, if the higher my realm, the less likely it is to give birth to children, then when I break through to the realm of heaven and man, or a realm higher than the realm of heaven and man, Isn’t your system ruined?”

[The host's worries are unnecessary. Even if the host breaks through to the heavenly realm and even becomes an immortal, the host can still get his wife and concubines pregnant, but the probability is small. Of course, this world cannot bear a real immortal. 】

Lu Chen frowned when he heard the system's answer. Although the system said so, he had already proven through practice how difficult it is to have a child now.

It was already so difficult for him to give birth to an heir when he was still a pseudo-celestial being. When he breaks through to the realm of celestial beings, won't the difficulty increase by an order of magnitude?

No, he had to make as many babies as possible while his realm was still relatively low. Thinking of this, Lu Chen glanced at the delicate bodies and buttocks of his wives and concubines in the yard.

It seems that before becoming a heavenly being, I have to work harder.

Just when Lu Chen was distracted, Mo Xing came to Lu Chen's side and said, "Your Majesty, all the circuits have been tested and can be officially powered on."

Hearing this, Lu Chen came back to his senses and said immediately: "Okay, get ready to power on!"

At this time, Mu Zixuan and the others also returned to Lu Chen. Chu Yuqin curiously looked at the glass-like objects pressed against the door and smelled: "Chen'er, can this thing really light up?"

Lu Chen said with a smile: "Just wait and see, it will light up soon."

At this point, Lu Chen said to Mo Xing: "Start with the third power supply, switch on and off every three breaths!"

Although this small amount of electricity cannot harm high-level warriors, and even has basically no harm to grandmaster-level warriors, for ordinary people in this world, electricity can still electrocute people to death.

After hearing Lu Chen's order, Mo Xing said excitedly:

"Yes, Your Majesty!"

They were witnessing history. The Northern Palace would become the first household to use electricity.

As the first electricity supply began, all the lights in the Northern Palace lit up.

Seeing this, the women screamed in surprise. Not only them, but also the servants and maids of the entire palace, and even the guards were frightened by the sudden brightness.

For a moment, the entire Northern Palace became as bright as day.

Although Lu Chen had reminded the people in the palace at the beginning that the bulbs would emit light tonight, so that they would not be too surprised, but hearing from others and seeing it with their own eyes were completely different.

They thought that these "glazed lamps" would be as bright as lanterns at most, but they did not expect them to be so bright, which made them feel that the Northern Palace was no different from daytime.

However, the light soon disappeared again. Seeing the light suddenly disappear, everyone looked confused.

Xiao Wenyao asked curiously beside Lu Chen: "Prince, why are those glass lamps not on? Is there something wrong?"

Lu Chen smiled and said: "No problem, I deliberately cut off the power for people. Although these household electricity can't cause much harm to high-level warriors, it is still possible to electrocute ordinary people, so it must be turned on and off three times when the power is on to prevent people from directly touching the wires and getting electric shocks."

Hearing Lu Chen's words, the women reacted instantly. It turned out that Lu Chen was so thoughtful.

Soon after Lu Chen finished explaining, the lights in the palace lit up again, and went out again after a while. Until the third time when it went out at home, the faint lights in the palace did not go out again.

Seeing the courtyard illuminated by the glass lamp as if it were daytime, Chu Yuqin couldn't help but sigh and said: "I didn't expect that I could see such a spectacle in my lifetime!"

Mu Zixuan asked beside Lu Chen at this time: "Prince, will the people of the Northern Kingdom be able to use electricity in the future?"

Lu Chen replied: "Of course, it will take a long time to make the machines for power generation and create the conditions for power generation."

"But within a hundred years, it will be no problem for the people of the entire Northern Kingdom, and even this world, to use electricity."

Hearing Lu Chen's answer, the women fell into silence. With electricity, the world will become so beautiful in the future, and the nightlife will be so rich in the future.

Lu Chen said: "Okay, you all go back and rest, it's so late."

After hearing Lu Chen's words, the women gradually left Fengyun Courtyard and returned to their own residences.

But they were destined to have difficulty falling asleep tonight, after all, the shock brought to them by the glass lamp was too great.

After all the women went back, Lu Chen looked at Mo Xing not far away and asked, "How long is the life of this light bulb now?"

Although the materials used to make the light bulbs have changed, the life is still not good. In addition, the light bulbs are not vacuum, so the life of these bulbs is still not very long.

Mo Xing replied, "Replying to the prince, the life of these light bulbs is about seven days at present, but if the air inside can be pumped out, the life of these light bulbs should be able to increase to several months. The several light bulbs that have been pumped out of the air for our experiment are still on, and there is no sign of burning at all. It's just that it's a bit difficult to make such a light bulb."

The current production of light bulbs relies on manual labor. To completely pump out the air in the glass, the strength of the light bulb maker must at least reach the level of a half-step master, and can reach the level of true qi release to make such a light bulb.

Of course, manual production is like this. Now they don't have much experience. When the technology matures and they have experience in the future, perhaps ordinary people can also make vacuum light bulbs.

Lu Chen thought about it, and then said: "Seven days is seven days, just replace it in time."

Now it's just a trial, so there's no need to worry too much about how long the lamp can be lit.

Lu Chen then said to Mo Xing and other craftsmen: "Okay, you've all worked hard, go back and have a good rest tonight."

Mo Xing and the craftsmen said in unison: "Thank you, Your Majesty!"

After the voice fell, Lu Chen asked the guards waiting outside the palace to send these craftsmen back one by one.

At the same time.

Wu Yunwan and Murong Xueer were sitting in the yard, staring at the yard that was illuminated by the glass lamp like daytime.

In fact, the two of them had heard that the lamp would be lit tonight. After all, they were also there when the craftsmen were pulling wires in the yard these days, but neither of them realized that the lamp would be so bright, and the lamp did not even require candles, which really shocked the two women.

Wu Yunwan said to herself: "How did he do it..." (End of this chapter)
