The sun scorched the earth, and the leaves on the mountains were dried up, losing their former vitality.

The weather is really getting hotter and hotter, and the previous fan didn't bring coolness, and Dianyu is now starting to study air conditioning.

She vowed to research it before the hottest summer days arrived.

Since the last time I told the air tree about her plans,The air tree went back to study.,The air conditioner that the air conditioner that the air feather said is also very interested.,These days, whenever I'm free, I'll come to the electric feather to study together.。

Although they failed countless times, the direction of their research gradually became clear.

In the last few days, in order to be more convenient to devote himself to research and experiments without being disturbed, Dianyu also deliberately rented a single room refining room at a high price to use.

It's good that Chen Jie sells blowers well, and she handed over the sprinkler to him, helping her earn a lot of spirit stones, otherwise she wouldn't be able to withstand the spirit stones burned by the research funds.

On this day, a loud cheer erupted in a refining room, and both Denyu and Soragi were too excited, they had failed countless times, and finally succeeded, and their grizzled faces could not hide their sparkling eyes.

Looking at the "air conditioner" placed on the ground indoors, feeling the coolness it exuded, Kongmu was about to cry with joy: "Little junior sister, is this the air conditioner you are talking about?" We've finally made it! It's not easy! ”

Looking at the empty wood covered with oil stains and dust, Dian Yu was also excited: "That's right, this is the air conditioner I said." It's so comfortable to blow in the wind! As he spoke, he couldn't help but close his eyes and look like he was enjoying himself.

This Xiuzhen version of the air conditioner is also too good, right, the external machine that is refined by the combination of formation and spirit stone refining techniques can be done, it is not as complicated as in the previous life, and it requires such a cumbersome thing as the external machine and the internal machine, and it can be done directly in a small box, the key is that it is also environmentally friendly.

"It's really good, this is much more saving spirit stones than using the cooling formation alone." The empty wood wiped the dust off his face, and touched the air conditioner like a baby.

This sentence reminded Dianyu that the air conditioner has been studied, and they already know the principle of how to use the cultivation method to make the air conditioner, and now they need to enter the stage of experimentation and improvement.

After all, every new product needs to pass layers of inspection and certification, so as to continuously improve and innovate.

"Senior Brother Kongmu, let's not be busy and happy just yet. We have made this air conditioner, but we still don't know the specific amount of spirit stones consumed and the use of it. Now we need to take a while to see if there is anything we need to improve on, and try to make the first work we worked together even better, and then wow everyone! After saying that, he raised his fist to cheer up.

Kongmu was said to be bloody, and he had long since lost his taciturn appearance, and nodded again and again: "Little junior sister is reasonable, or you are more thoughtful." ”

So, for the next few days, Dianyu and Kumu were in their rented exclusive R&D room, blowing the air conditioner, testing the performance of the air conditioner while making data records.

After many tests, the two made an analysis and summary of the recent observation record of air conditioner usage:

1. The refrigeration effect of the air conditioner is good, but it lacks the function of gear adjustment, and there is no heating function.

2. The consumption of spirit stones is 3 lower-grade spirit stones per day, which can save 2--3 lower-grade spirit stones compared to a single cooling formation, and can be adjusted in the direction of more economical spirit stones.

3. There is a little noise when the air conditioner is used, which is still too noisy for monks who want to practice quietly.

4. If you want to turn off the air conditioner when you go out, there is no switch, and you can only "cut off the power" by removing the spirit stone, which is inconvenient.

5. The appearance is not beautiful enough.

......

By comparing these records, Electric Feather and Kuragi have undergone a new experiment and adjustment.

First of all, I went to Fang Market and found some materials that can isolate the aura, make it into an insulated switch, and adjust the size of the gear.

In terms of exterior design, Dianyu thought of Yuci.

I saw a painting of Sister Yuci in the place where Senior Sister Yuci was resting before, and it seemed to her that the painting was very good, so she specially asked the ingenious Senior Sister Yuci to draw the appearance design drawing.

Kongmu added a small soundproof array, and the electric feather also made some improvements in the exchanger, and a series of operations were down.

Finally!

The first air conditioner exclusive to the Xiuzhen realm was born!

"Hello Senior Brother Chen Jie, I'm Dianyu. Recently, I have researched a new thing, you have time to come to the xx refining room of the outer peak of the refining peak, let's talk about it in detail. ”

Chen Jie, who had just returned to the sect, received a message from a lightning feather, and rushed over as soon as he was free.

Electric Yu rarely takes the initiative to contact him, and this time he contacted him, and it is estimated that there is really something good.

When he came to the outside of the refining room, he knocked on the door outside, and after receiving the promise, he strode in, but was stirred by the oncoming cool breeze inside: "Wow! Senior Sister Dianyu, you are so extravagant to use such a good cooling formation, how many spirit stones do you have to spend?! ”

Chen Jie didn't expect this little junior sister to be so generous, not only opened a single room refining room, but also used such a good cooling formation in the refining room.

Could it be that she is some invisible rich second generation? But looking at the way she bargained with herself before and didn't give an inch, it didn't look like it?

"Senior Brother Chen Jie, you came so quickly, it's really good! This is not a formation, this is the air conditioner newly developed by me and this senior brother of Kongmu, which is still in the experimental stage and has not yet been officially put into use. I called you here today for this purpose. ”

The misunderstood Dian Yu waved her hand again and again to explain that she didn't want to be labeled as an arrogant child.

Chen Jie listened to Dianyu's words, and his attention was instantly attracted by the small box that Dianyu pointed to.

"It turned out to be the coolness exuded by this baby, looking at its square and inconspicuous appearance, it can actually be compared to the cooling formation." Chen Jie was overjoyed to check around the air conditioner, wanting to get started but afraid of breaking it.

"Senior Brother Chen Jie, this air conditioner we have researched is much more practical than the ordinary cooling formation, it is small and portable, do you see this button? This is a switch, you don't need to take out the spirit stone to stop using it, and you won't consume the spirit stone after you stop using it. And the button next to this switch can adjust the gear to control the temperature. ……”

Chen Jie was introduced by Dianyu in a series of ways, and he wanted to have an air conditioner, he had a hunch about this thing, and it would definitely sell well!

Next, the two had a series of discussions on the sale of air conditioners, and Kumu was of course added as a technician.

After waiting for the electric feather to return for a long time, Yuci was also called an appearance designer to join the discussion.

The four of them had a heated discussion, and finally selected the bazaar organized by the outer disciples the day after tomorrow as an advertising position and the first wave of pilots.
