It was not too early to return to the mansion. I walked along the way and found that it was not only tiring, but also taking time. There were not many servants in the mansion, and there were even fewer maids. Xiaoxiang was also very tired after drinking Liuli, so the other two maids were temporarily busy.

"I walked so big today. In fact, there is another latest discovery. I didn't tell you." Everyone gathered in Yang Yichuan's room. There are two tables in the room, enough for eight people to sit. Now there are two tables for men and one for women.

Yang Yichuan took out a small iron box from the house, which was as big as a shoe box. The main reason was that the style was a bit ugly, and just looking at the appearance, ordinary people would definitely not see what the iron box was used for.

This is the sample of the cooling air conditioner given by the system. It can also be said to be the lowest-end air conditioner. It looks really ugly. Yang Yichuan was just the first generation of air conditioners. He was also helpless. With the development of technology, he would slowly update and replace it. The core technology of cooling air conditioners has been mastered. The remaining updates can only be improved in appearance and optimization of attributes. These things can be left to others to do at that time.

Yan Yuzhang was puzzled when he saw the cooling air conditioner that Yang Yichuan took out. Judging from Yang Yichuan's appearance, he seemed to be a treasure, but he was really not a good match for this. "Boss, isn't it that you have something in your iron box that we don't know?"

"Brother Chuan, this iron box is so ugly." Yang Ruxu, the beauty control party, has already begun to bury this iron box.

The eyes of others were also gathered on Yang Yichuan's iron box, and Liuli and Xiaoxiang were also confused. However, Yang Yichuan would study or manufacture it from time to time, so it was normal for them to have something they didn't know.

"Dangdangdang, dang." Yang Yichuan also gave this iron box a joy, but no one could understand the feeling that Yang Yichuan wanted to show, and it was inevitable that he was a little embarrassed.

"Ahem, this is what I have developed. It is also made by using the methods of the spiritual array master. The production difficulty is several times more complicated than that of the lighting. If I do my best to make it, I will probably be able to make three cooling air conditioners in one day."

"Yes, you heard it right, this thing is called cooling air conditioning."

The other seven people looked at Yang Yichuan with a slightly quarrel feeling, but did not speak, and the incident became unlucky again. Yang Yichuan felt extremely embarrassed.

"Forget it, I'll continue to talk about it. This cooling air conditioner, as the name suggests, is a device used to cool down. It's hot summer soon, and even in the house, it will be very hot. At this time, you need a cooling air conditioner. Place the cooling air conditioner in the house, which can slowly release the cold air. The temperature in the house slowly drops down so that the house will not be so hot."

"Of course, you may say that it is very simple and very simple things that can be achieved with a spiritual array. In fact, it is not. The methods of the spiritual array master can indeed cool down. Would you put an ice array at home to cool down? I'm afraid you will be frozen to the point of getting sick? Other ice formations will also take effect quickly and then start to cool down. Once used, it will cool down a lot, which is difficult to control."

"This is the magic of cooling air conditioners. They can be regulated. Cooling air conditioners can be divided into five levels, one, two, three, four, and five. The higher the grade, the heavier the cold air it releases, and the better the cooling effect. Of course, it can also make people sick. At that time, you can adjust it yourself according to the external situation and your own situation. If you feel hot, you can increase the grade. If you feel over, you can adjust the grade back."

"I'll give you some practical operation now. Now it's the first level, come and feel it."

Although it is not summer now, it is almost dusk and not as hot as noon, it is not cool. After Yang Yichuan turned on the air conditioner, he found that the indicator light was not on. Not only was the indicator light not on, but Yang Yichuan did not even feel that the air conditioner was working.

"System, system? There will be no problem with the air conditioner you gave me, right?"

"The host is indeed stupid. Don't you know that you want to release the spirit crystal? You know on earth that you have to plug in, turn on the power, and put the battery. Why do you become so stupid when you get here? I am really disappointed with you." The system loli was still holding her hands behind her back, looking as if she was so angry that she was so angry that Yang Yichuan was furious.

"No, can you give me a sample without a battery?"

"Why do you need to bring a battery? It's definitely the case that it's a cooling air conditioner sample, and you won't give you anything more."

“…”

"Okay, I'll endure it." Yang Yichuan had no choice but to the eyes of everyone. Yang Yichuan's old face turned red. Why did he become like this after he came back? He was about to become an embarrassing king.

"Ahem, sorry, I forgot to put the spirit crystal." Yang Yichuan took out the spirit crystal from the cabinet just now and put it in the cooling air conditioner. It is also a medium-sized spirit crystal. According to Yang Yichuan's estimate, this spirit crystal can also be used for air conditioning for more than a month. If you use a large-sized spirit crystal, it may be used for one year. This is not good.

After putting the spirit crystal, turn on the energy switch and it has been adjusted to the first gear. In the gaps in front of the air conditioner, everyone can feel a slight cool breeze blowing out, which is very cool, but not cold.

Everyone reached out to feel it, and it was true, "It's indeed a bit cool. The wind is not strong, so it won't feel cold."

"Try the second gear quickly."

At the request of everyone, the second gear was turned on. Of course, the wind was still not strong, but it was a little cooler. This was the real coolness. If you can feel such coolness in the hot summer, it would be life.

Yan Yuzhang's eyes shine. What is the biggest problem in summer? Of course, it is hot and it is unbearable. Now with the air conditioner, do you think you can be unhappy?

"This, it's really cool, but it can only be felt near the air conditioner, right? Could it be that everyone needs to take one nearby?"

"Of course not. Putting this in the room will slowly cool the whole room. If you want to speed up, you can also adjust it to a higher level first, then adjust it to a third or second gear to stabilize it, so that you won't feel cold or get sick by freezing."

Another amazing invention, Yang Ruxu was already very admiring to Yang Yichuan, with little stars in her eyes.

"Brother Chuan, you are so awesome, so great."

"Boss, can we learn the spiritual array masters we brought with us? This thing must be sold for a thousand taels of silver, right?" Yan Yuzhang also fell into the eyes of money. It is no wonder that the emergence of air conditioners will indeed change a lot of things.

"Of course, I will teach you the spiritual formation masters, and I will ask you to take some back to the palace. These are not a problem, so don't worry." Yang Yichuan also expressed his opinion that if there are good things, we must share them together.

"Boss, you are so righteous."

"Okay, stop making trouble. You have watched the air conditioner. The rest is almost done. Come out and walk around. We will have dinner later. There will be programs and entertainment activities in the evening?" Yang Yichuan said to everyone with a smile. Yan Yu Zhang stood up excitedly and rushed to Yang Yichuan's beauty.

"Boss, where are we going to play tonight? Is there any beautiful little lady in Nishiwa Castle? Is it comparable to the Yanliu Girl in Kyoto?"

“…”

Yang Yichuan really wants to say, Big brother, you think too much, why do you think about that when you talk about entertainment activities? This is not good. Although they are really just going to watch girls and listen to music, they can't always go to that kind of place.

"Don't think too much, just stay at the mansion. You will know after dinner." Yang Yichuan still pretended to be mysterious, Xiaoxiang and Liuli knew about it. Yang Yichuan planned to let them sing a few songs taught by Yang Yichuan.

"Sister Liuli, do you know what Brother Chuan is saying?"

"I know, I know." Xiaoxiang said happily, and was still eating the crispy gum that Mr. Fu brought back from Kyoto. However, Xiaoxiang, who was about to speak, was stopped by Liuli with her eyes. She could only curl her lips and said aggrievedly, "Young master and Sister Liuli won't let me say it."
