Driven by spiritual power, the blazing fire burned more vigorously, and the tongue of fire licked through the stove, emitting waves of high heat and temperature.

"Oo~boom~" In the sound of striking iron and the sound of high-temperature blasting, bursts of sparks were splashed.

Electric Yu raised his arm to wipe the sweat from his face, and continued to refine the materials in his hand with a sigh of relief.

It's about to enter summer, and now the weather is getting hotter and hotter, making the already hot refining room more like a furnace.

Back at the residence, although the temperature was not as hot as in the refining room, I could still feel the increasing temperature.

Dian Yu couldn't help but complain to Yuci: "Senior sister, why do I feel that it is getting hotter and hotter these days?" As he spoke, he fanned it with his hand.

Yu Ci smiled softly: "Xiao Yu, don't you know, in order to be able to temper our sword at any time, our Sword Sect is already in a region rich in earth and fire, and the temperature is usually higher than that of other regions. It's summer, so it's going to be even hotter. ”

Senior Sister wiped the sweat from Dianyu's forehead and continued: "Now your cultivation is still low, and your spiritual power reserves are insufficient, so you feel hot. When you enter the foundation building period like those senior brothers and sisters, you can rely on spiritual power to dispel the heat. ”

"Ahh - "Dian Yu wailed: "Wait until the foundation building period? I've just entered the Qi Refining Period now, so how many years will I have to endure this heat?! ”

You must know that as a monk, you are more resistant to cold and heat than ordinary people, but the temperature here is usually more than 30 degrees, and now it feels faintly about to break through 50 degrees.

Although it can be relieved occasionally with spiritual power, it is not easy to absorb spiritual power reserves, and it must be kept in case of emergency.

Especially for disciples like those who need to go out to run errands, if they encounter an unexpected situation, it will be a big trouble if they don't have spiritual power to use.

Therefore, there are generally very few monks below the Jindan stage who use spiritual power to resist these "tests" that can be resisted by their physical bodies and wills, and there are even fewer monks above the Jindan stage, after all, their physical bodies have reached a relatively strong point at that time.

"Why don't you buy some cooling formations and use them?" Yuci saw that Dianyu was indeed uncomfortably hot, and proposed.

"Alas! It's better not to do it, it's very expensive to buy a formation, and the formation consumes a huge amount of spirit stones, so we should save the flowers. ”

Although she has recently earned some spirit stones by selling sprinkler irrigation machines, it can only be said that her learning path can only be said to be a drop in the bucket, and it is better to save some money and use it on the blade.

However, Dianyu has not given up looking for a way to cool off in summer, and she has been thinking about how to solve the problem of heat these days.

As far as she knew, their sect and even the entire immortal cultivation realm, the number of monks in the Jindan stage and below realm accounted for the largest.

The higher the realm, the smaller the number of people, such as the Xuanzhen Immortal Venerable who had ascended from the Sword Sect before, he was the only one such a Tribulation Period cultivator in the past 10,000 years.

In this way, if she invented something that could cool down and save spiritual power, wouldn't there be a big market?

Just do it.,The first thing that came to mind was the electric fan.,After many experiments.,And I went to find the empty wood brother who knew how to burn the formation.,Help burn the formation.,In the end, the fan was made.,But....

In the refining room, a senior brother was caught off guard by the sudden strong wind, and hurriedly stabilized the materials in his hand and looked at the culprit!

Seeing clearly that it was a little junior sister who was tinkering with something, he hurriedly shouted: "Hey, hey, this little junior sister, what kind of magic weapon are you refining?" If I blow all the fire to the side, I can't concentrate my fire to refine the materials! ”

The cheapest refining room that Denyu is renting now is not a single room, but is shared by several people.

As soon as the electric fan of the electric feather was loaded with spirit stones, a strong wind blew the ground fire in the refining room to the ground, and a stream of heat raised everyone's hair.

Dianyu hurriedly took out the spirit stone that was the driving force, and wiped the sweat on his head, "I'm sorry, senior brothers, my name is an electric fan, and it hasn't been completely refined yet, so I'm really sorry to disturb everyone." ”

I used to eat watermelon with a fan in the summer, how cool it was! What Dian Yu didn't expect was that the temperature here was high, and the wind blowing was all hot air, so what should I do if it's even hotter now?

The senior brother circled around the freshly baked floor fan of Dianyu, not understanding what it was, but he couldn't stand the hot air blowing from it.

"It turns out that it hasn't been refined yet, no wonder it makes people so uncomfortable." He rudely wiped the beads of sweat from his head, and kindly reminded Dian Yu: "This little junior sister, I see that your refining technique is quite proficient, keep up the good work." It's just that if you want to test it in the future, you must not do it in the refining room, it is best to find a place where no one is around, otherwise it will not be good to cause unnecessary problems. ”

"Thank you brother for your kind reminder, I will definitely find a place where there is no one next time to conduct another experiment."

On the way back, Dianyu has been pondering there, how to turn hot air into cold air, or directly make air conditioning?

But the electric fan has already been made, so you can't waste it, and see if you can improve it yourself.

The next day, Dianyu found the empty wood, and the idea of the two of them to get together really increased, and they found that although the electric fan would blow the fire to the ground, it could still fuel the fire as long as it was used properly.

Electric Yu slapped his head directly, isn't this the blower in his previous life? Why hadn't she thought about it sooner?

They made some adjustments, and after several experiments, they finally made up the blower used for burning coal in the countryside in the previous life.

On this day, Dian Yu was in the refining room, and after confirming that there was no problem with the blower she had newly refined, she began to try to use it to refine materials, and was seen by the disciples on the side, and the more she looked at it, the more envious she became.

"I'm sorry for this little junior sister to disturb you, I just saw on the side that you used this magic weapon refining material, it's very useful, I don't know where you bought it?"

Dianyu looked up and saw that it was a simple and lovely senior brother, who was now looking at her blower with bright eyes.

"Senior brother, this is called a blower, which I refined myself, and it is very useful to use to promote the ground fire, and it can also adjust the gear to change the size of the fire, which is very useful for the smelting of materials in the early stage. Although the later fusion process can't help much, it saves a lot of aura and energy in the early stage, and the success rate of the later fusion is greatly improved! ”

A few disciples next to him who pretended to pass by casually and pricked up their ears couldn't help but cast their eyes too, they had just seen the usefulness of this blower, but they didn't expect that there were so many benefits.

Everyone expressed their desire to have it, and finally bargained and sold it to everyone for ten low-grade spirit stones.

The circle of the outer peak of the refining peak is so small, some people go back to talk to their good friends, and some people are asked by others when they use it, and soon many people know that Dianyu is selling blowers.

Having witnessed the benefits of this small blower, the disciples who wanted to buy it came up one after another, and kept Dianyu busy in the past few days.
