Xia Yuan said with a smile: "Compared with the photo symbol, the projector is of course much more simplified. The photo symbol is a holographic three-dimensional display, with a large amount of information and high energy consumption. The projector only needs a flat display, which has a small amount of information and low energy consumption. Although it is certainly more complicated than a record player, it can still be done to be civilian. ”

There were many new words in Xia Yuan's words, and the three sisters couldn't understand them for a while. Seeing this, Xia Yuan took out two simple talismans and said: "This is the projector and camera I refined, it is considered the original model, it is still used in refining techniques, and the function is also imperfect, but it can give you a general understanding of the principle of the projector and the camera." ”

Xia Yuan demonstrated to the three sisters the projector and the camera, the projector is equivalent to the rear projection on the earth, and the camera is naturally used for recording. This flat display of images was a novelty for the three sisters, who took over the projector and the camera and tossed it with great interest.

Xia Yuan said: "The next thing you need to do is to simplify the projector, just like the record player, so that ordinary people can use it." It is also necessary to make some production equipment so that ordinary people can produce it. The camera doesn't have to think too much, it is refined by refining the tool, and the camera mainly considers how to improve the clarity of the recorded image. ”

Lan Ling, who had the most research on refining tools, looked at the original model of the projector, thought for a while, and said, "Young Master, if it is such a simplified image function, according to the method of the record player, it should be able to make a projector. ”

Bai Xue also said on the side: "Young master, don't worry, such a projector will definitely be made."

Xia Yuan said: "This projector, the clearest image projected, should be controlled in the range of three feet long and two feet high, so that it is convenient to watch indoors." In addition, you refine a large projector that can project a projection that is nine zhang long and six zhang high, and use the method of refining to ensure that the cultivators of the fourth layer of the quenching body can drive it. ”

Bai Xue asked curiously, "Why do you want to be such a big guy?"

Xia Yuandao: "The projector is much more complex than the record player, and the energy consumption is also high, and the average family is estimated to be unable to afford it. With this kind of large projector, it can be shown to everyone in some large places for a small fee.

Yuehe said: "Young master, I can still understand the record player, I can record the singing of some excellent singers, so that everyone can listen to good songs." But what's the use of this projector? What can it put in?"

Xia Yuan said: "You can put some customs, such as recording some of the landscape of the capital, you can enjoy the scenery of the capital without going to the capital." ”

Yuehe said: "This is good, but the projector is much more complicated than the record player, and it will definitely be much more expensive than the record player, if you just look at the scenery elsewhere, will not many people buy it?"

Xia Yuan smiled: "Are you worried that I will lose money, girl, you are really a housekeeper, very virtuous." Don't worry, young master, I have my own backhand, and this projector will definitely not fail. ”

Yuehe heard what Xia Yuan meant in his heart, and he was a little nervous in his heart, for fear that Bai Xue Lanling would find something abnormal, so he hurriedly changed the topic and said: "Lin Hu has started cultivating in the past few days, I used my divine sense to investigate, and found that he has a very good talent and is making rapid progress. ”

Xia Yuan smiled when he heard this: "It seems that I have inadvertently discovered a talent, I will take a look at him." Saying that, Xia Yuan released a pseudo-divine thought and swept towards the Lin family.

The Lin family, Lin Hu was gathering qi in the quiet room, Xia Yuan's divine sense swept over, and Lin Hu's state was immediately clear.

Retracting the pseudo-divine thought, Xia Yuan sighed: "What an unexpected joy, Huzi's cultivation talent is too good, it should belong to the level of a genius, I think his talent should surpass Xia, and it is almost the same as the talent of Gu Ning Shuangxian." ”

Yuehe said: "Then I will spend more time guiding him, so that he can achieve success in cultivation as soon as possible, maybe he can help you in the future, young master." ”

Xia Yuan shook his head and said, "No need to do this, we just helped Huzi embark on the path of cultivation, and if we help him too often, it will make him dependent." There are many talented people in this world, but only a few are firm in their hearts and have achieved success in cultivation. Let Huzi cultivate on his own, and it is enough to instruct him once or twice a month. If he can really cultivate hard for a few years and develop a tenacious heart, it will not be too late for us to cultivate him. ”

Yuehe nodded after hearing this, Lin Hu was only ten years old, so it was good to observe. If Lin Hu develops a tenacious heart, it will not be too late to cultivate him.

Xia Yuan instructed Yuehe again: "In the future, I will gradually become known to the world, once I am sharp and have a conflict with some forces, they may fight your idea." In the future, you should be more vigilant, and don't be negligent and slack off just because your cultivation has been high and your days have been dull for too long. Girl, you are in charge of the overall situation at home, you must be calm and composed, always be on guard against small attacks, and take care of the two small ones, thank you for your hard work. ”

Yuehe said: "Young master, as your girl, and Xue'er Ling'er's eldest sister, I should do anything hard to talk about whether it is hard or not." There is a large array you have arranged at home, as long as we are vigilant, it should not be a big problem. But you, young master, are alone and have no one to help the village, so be careful. ”

Xia Yuan smiled: "I haven't married a daughter-in-law yet, so naturally I'll be very careful, girl, don't worry." ”

Yuehe heard that Xia Yuan was open-mouthed again, and secretly communicated in public, so she was anxious, and hurriedly changed the topic: "Young master, it will take you a long time to go, I have bought you a few sets of clothes, shoes and socks, you can put them away, and change them when the time comes." You should pay more attention, your clothes, shoes and socks are stained, you should change them frequently, don't be too sloppy. You are a person who does big things, don't let others laugh at you because you are not well-dressed. With that, Yuehe began to take clothes, shoes and socks out of the storage bag.

Xia Yuan watched Yuehe keep taking out a set of clothes, shoes and socks, and was dumbfounded: "How many sets are these? I see more than dozens of sets! So many, how long have you been doing it?"

Yuehe replied while taking things: "It didn't take long, young master, don't forget, I am now a cultivator in the late stage of Liding, and my energy, eyesight and hand strength are very high, and I can sew these very quickly." ”

Xia Yuan was very moved: "No matter how fast you move, it will take a lot of time for these tedious sewing." Have you not cultivated for the past few days, and have been doing this, I ......"

Yuehe was worried that Xia Yuan was talking nonsense again, so she hurriedly interjected: "I didn't just do this. The incense on the clothes, shoes and socks, and the sachets on the belt are all made by Xue'er, and the various ornaments inlaid on the clothes and shoes are all made by Ling'er. Master, you are so good to us, we should do something for you. ”

Bai Xue and Lan Ling also said in unison: "Yes, young master, you are so good to us, we should do something for you." ”

Xia Yuan felt very relieved and happy when he heard this: "Girls, you are so good, young master, I am very happy." ”

Seeing that the young master was happy, the girls were very happy, all smiling like flowers, and for a while, warmth and happiness filled the small courtyard
