"If it's for short-term use, just use the battery directly, the battery is something that holds electric energy, and every bathroom has to be equipped with one. However, the battery is like our spirit stone, the aura in it is limited, and it is impossible to absorb it indefinitely, right? Tang Wen said.

"Of course, a spirit stone just has that little spiritual energy, and it will be gone after inhaling it." Western Xiangyun nodded.

"It's the same with batteries, you can't light the lights when you run out of power.

That's the same as oil lamps need to be refueled, but the batteries have to be transported from the distant Xuan Netherworld, which is also very expensive.

So, in the long run, my suggestion is to install a fan. Tang Wendao.

"What is a fan?" Deputy City Lord Jiang asked shamelessly.

"It's kind of like our windmill, but it's very high, forty or fifty feet high.

This thing stands on the hill behind the city lord's mansion, and when it rotates, it can generate electricity.

Then, through the copper wire, this electrical energy can be fed into the lamp, so that the lamp can emit light.

Of course, there are a lot of complex mechanisms that need to be set up.

There are also copper, silver and other mechanism configurations.

If you have a wind turbine, you won't need batteries in the future. However, fans are too expensive. Tang Wendao.

"It's so high, it must be expensive." Western Xiangyun Road.

"Needless to say, how much effort does it take for a big guy forty or fifty feet tall to transport it back, and the freight alone is scary, right?" Deputy City Lord Xixi Heluo said.

"Forty or fifty zhang high, standing up is the height of a dozen stories of pagodas. Such a tall thing is not light, is it? The Great Elder actually asked.

"Of course it's not light, a wind turbine weighs 500 tons." Tang Wendao.

"It's not heavy, five hundred pounds." Wei Xiaolin snorted lightly.

"Elder Wei, it's not five hundred catties, one ton is the weight name of the Xuan Netherworld, one ton is equivalent to 2,000 catties." Tang Wen also had to popularize scientific and technological knowledge.

"One ton is 2,000 catties, and five hundred tons is not 1 million catties?" Jiang Wei did the math.

"1 million catties, so heavy, and so high, even a strong person in the Divine Consciousness Realm can't move it. Elder Tang, how did you bring it back? Cui Shigong sneered.

"Could it be that Elder Tang hired a few Divine Realm powerhouses to carry them together?" Wei Xiaolin scoffed.

"Can you afford it? One of your fans is not enough to sell thousands of high-grade spirit stones. The Great Elder snorted.

"Of course I have to dismantle it and transport it back, how can I afford to hire it in the Divine Consciousness Realm? Besides, in the Divine Consciousness Realm, are you willing to do such rough work as lifting a fan with a spirit stone? Aren't people horses? As soon as Tang Wen's words fell, he immediately burst into laughter.

"So, a wind turbine has to fit hundreds of wagons and hire more than 1,000 people to protect the transportation along the way.

I see that the city lord's mansion consumes a lot of electricity, and there are no two fans that can't be used.

Don't talk about anything else, the shipping cost alone is sky-high. However, although the fan is sky-high.

However, once installed, it can be used for more than ten years.

Compared with changing the battery, it is still much cheaper. Tang Wen said.

"How much does a frame cost, you just say it." Seo Kong Ming asked.

"Ten thousand high-grade spirit stones." Tang Wendao.

"Ten thousand?" Suddenly, all the elders gasped.

"Two is 20,000! I can't afford it, I can't afford it. Wei Xiaolin shook his head.

"What's in it? Let's continue to use candles, actually, candles are not bad. Elder Cui said.

"Nice fart, can you compare to an electric light? Don't talk about anything else, it's just that our City Lord's Mansion has many fires every year.

The fire alone can burn away thousands of our high-grade spirit stones, and sometimes it will burn people to death if we are not careful.

If it was our family that burned to death, how sad would it be?

However, people's electric appliances will not catch fire, and they will be saved in a few years. Li Yu snorted.

Gu Xuan

"But two fans cost 20,000 yuan, you come out?" Cui Shigong snorted.

"It can be saved in other places, for example, if you have electric lights, you don't have to burn candles, which is also a lot of money." Li Yu said.

"Actually, the role of fans is not only used in electric lights and bathrooms." Tang Wendao.

"What else can it do?" The Great Elder snorted coldly.

"Stir-fry and stew." Tang Wendao.

"Hahaha, Elder Tang, you don't look like a liar.

If it makes sense to use a fan to generate electricity and light a lamp, the fan is so big, how to stir-fry?

It's not a stove, it's not a pot? Not even firewood. Wei Xiaolin laughed sarcastically.

"Hehe, Elder Tang is very powerful, he can stir-fry directly with a piece of iron and destroy the real fire. However, Elder Tang is so weak, it seems that he doesn't even have real fire, right? Elder Cui laughed.

"Where did the real fire come from, it is said that Elder Tang is also in the second-grade realm, and he doesn't even have true qi." The Great Elder snorted.

"Okay, if you don't believe me, I'll do it live." Tang Wendao.

"Elder Tang, please perform." Western Xiangyun said with great interest.

Tang Wen nodded, took out a small fan from the void bag and stood on the main hall, and the fan was only seven or eight meters high.

Because it is a custom-made integrated fan, even the substation is mixed together, and it is 240 volt alternating current as soon as it comes out.

Tang Wen took out an induction cooker and put it on the table, set up an iron pot, and plugged it in.

Below, I took out a large light bulb, the 200-watt kind, and plugged it into the storage battery of the fan.

Here, I took out a few plates of cut vegetables from the empty bag, including meat and fish, including MSG, soy sauce and other seasonings.

"Do you see, this is the fan, but it's a miniature version, and the one I talked about earlier is the largest one.

However, the mechanisms are pretty much the same.

However, the wind turbine also needs to rotate the blades to generate electricity. Therefore, I asked Deputy City Lord Jiang to come over and use his palm power to help me turn the wind blades, so that I could generate electricity.

Of course, that's because there is no wind in the main hall.

If you stand outside, as soon as the wind in the air passes, the blades will turn on their own.

The mountain behind the city lord's mansion is very high, and the wind turbine stands up and goes straight into the clouds, and the wind must be not small. Tang Wen said.

"So, the faster the blades turn, the more electricity is generated?" Li Yu asked with a smart head.

"Of course." Tang Wendao.

"Then I'll work with Deputy City Lord Jiang to help you turn the wind blades, otherwise, it's too tiring to rotate the palm power alone, and you need to relay to make the wind blades rotate continuously and quickly." Li Yu said.

"That's better, please." Tang Wendao.

Below, Jiang Wei and Li Yu appeared, Jiang Wei destroyed the palm power, and suddenly, a gust of wind noise blew towards the wind blade.

The fan blades began to rotate slowly, and then, Li Yu slapped again, so that the two of them cycled back and forth, and the fan blades turned faster and faster.

"It's lit up, it's lit up." Soon, the electric lights were raised, and suddenly there was a pot boiling in the main hall.

The elders all cried out in surprise, as if a child had just received a bag of candy.

Below, Tang Wen pressed the switch of the induction cooker, started heating, and poured oil into the pot. Soon, a trace of smoke began to come out of the oil pan.

Then, Tang Wen threw chili peppers and other materials into it and began to stir-fry the chicken butt......

Throw in the garlic, pour the seasoning, and a fragrance will come.

Soon, several dishes, including a bowl of soup, came out of the oven, and the elders were dumbfounded and swallowed wildly.

"Elder Tang, can I taste it?" Western Xiangyu asked.

"These are all clean, I specially fried them with special seasonings brought back from the Xuan Netherworld, the taste is a little different from ours, Elder Xiangyu, please try it!" Tang Wen said with a smile.
