If someone asks, what kind of spirit demon is the most popular in summer?

The answer must be the Ice Spirit Demon.

Many high-end restaurants, inns and even in the tram in the imperial capital need to hire one or more ice spirit demons.

Not only can it reduce the environment to a suitable temperature, but it can also provide iced ingredients.

The long summer in Languicheng was once a nightmare for many people, but it is precisely because of the existence of the Ice Spirit Demon that summer has become better.

If Dihua Inn could have an experienced Ice Spirit Demon, it would be easier to make money.

But the hiring fee is tantamount to a sky-high price for them.

In this world, besides the spirit demon who awakened the Ice and Snow Demon Technique.

The refrigeration methods known to the world are only those mysterious human magic masters - the disciples of Xuanmen and Xuanshi.

I have to mention the subject of metaphysics here.

Religions in the world present a situation where all directions are promoted together before Buddhism is expelled.

Buddhism, Taoism, Confucianism, Xuanmen.

Buddhism was excluded by people all over the world for some hidden feelings and was expelled to a place where no one cares about it.

After Buddhism left, it showed a three-legged tripod.

The Xuanmen is not only the smallest number of people, but also the most mysterious.

Its mystery lies in the wonderful ability of metaphysics, which can do almost everything other than common sense.

There are all kinds of strange abilities.

Different from Taoism.

Taoism uses natural celestial phenomena, and carefully cultivates hexagrams, talismans, and arranges formations, and mainly practices the way of heaven.

All Taoist abilities come from nature.

And the ability of the Xuanmen disciples... no one can tell where they came from.

The teachings of Xuanmen are divided into five steps.

Those who climb the fifth step are called Xuanshi.

This is similar to the study of martial arts, which are divided into five steps.

The martial artist will practice martial arts to the fifth step and will be called the Grandmaster.

The master of sword cultivator is called the sword immortal.

In ancient times, countless people thought that the disciples of Xuanmen were celestial beings descended to earth.

But later more and more people discovered it.

When the disciples of Xuanmen lost those magical magic, they were actually the same as ordinary people.

It can also be born, old, sick and die, and also has seven emotions and six desires.

Some Xuanshi masters who possess great magic will practice martial arts because of their guilt of possessing a treasure in order to protect themselves.

Therefore, over time, the saying that people in Xuanmen are immortals will be defeated without any attack.

Later.

The people in Xuanmen are commonly known as "half demon" among the people, and the name of this half demon is getting louder and louder.

Because their magicality is no less than witchcraft.

So when the abnormal thing like iced drinks appeared in summer, Qin Yi only got these two answers in his mind.

Qiuqi shook her head.

"None of them, I just used something very simple."

As he said that, he took out a cloth bag from his pocket and handed it to Qin Yi.

Qin Yi opened the cloth bag and saw a few white and gray-yellow stones inside.

Qiuqi explained:

"This kind of stone is called saltpeter. When dissolved in water, it absorbs heat and reduces the temperature, so it can be used to make ice."

The little dihua next to her lit up slightly.

Say a low voice.

"Saltpe, is there something so magical?"

"You used that broken pot in the kitchen for half a day to smack it up for such a stone?"

Qiuqi nodded.

"Yes, there is no air conditioner in this broken place, which makes people feel uncomfortable."

"I'm not saying the inn is broken, I'm saying that the world is fucking."

"We have to find a way to make life easier."

Qin Yi and Xiao Dihua looked at each other.

Ignore the incomprehensible words he mentioned.

A Tan jumped up.

Although Bing is opposite to his ability, after he transforms into a human, his body is no different from that of ordinary people.

It doesn’t mean that the body is charcoal, so I can’t drink ice water.

"It's delicious, is there any more?"

Qiuqi smiled and said, "There are still many in the kitchen."

A Tan ran out happily.

Only Qin Yi and the other two were left in the room.

Xiao Dihua said it seriously.

"Boss, do you think this is not a godsend?"

"The stone created by Mr. Qiu is simply a summer weapon. You don't need to hire an ice spirit demon to have the same effect."

"The inn business will definitely get better because of this, you don't have to take risks anymore."

Qin Yi pinched her chin and thought for a while.

He looked up at Qiu Qi.

He is not a fool either. He can see that the value of this kind of stone is indeed very high for the current inns.

"You really gave me a big surprise."

"How did you...how did you make this kind of nitrite, saltpeter?"

"What are the raw materials? Is it possible to increase the manufacturing volume?"

Qiuqi explained:

"In fact, the principle is very simple. It is to extract as much potassium nitrate from the nitrosodium present in nature as possible and remove impurities. The finished product is saltpeter."

"Many of the raw materials... can be used as raw materials, such as the stones in the pits, the manure accumulation in stables and pig nests, and the walls of old houses."

"In addition, this is still a Chinese medicine, which may be available in some large pharmacies."

"There are still certain saltpeter ores in nature, but the amount is not too large."

Qin Yi and Xiao Dihua's eyes became strange.

Xiao Dihua asked tentatively:

"Can you create such a magical stone with those messy things? Is there such a beautiful thing in the world?"

Qin Yi stood up and walked to Qiuqi's side.

"Now it seems that you are a person with great ability."

"You made this kind of saltpeter. I can't force it to take over and make profits for myself..."

The little dihua next to her rebuke.

"boss……"

Qin Yi reached out to stop her.

"But, I can buy saltpeter from you. After you make it, I will buy it. This is the right way..."

"You can decide the price."

Qiu Qi shook her head.

"Boss, you're so harsh, it's all a slight effort."
