Three days passed quickly.

Xu Fan was locked in the house, except for eating and drinking, he didn't even sleep, and spent almost all of his time reading "Novice Alchemy Experience".

With his current cultivation, in fact, the need for food and water is getting smaller and smaller, but the habit of nineteen years can't be changed for a while.

Who Chen Chuan's ancestor is, Xu Fan doesn't know, but the alchemy experience he wrote is simply tailor-made for Xu Fan.

It is written in great detail, with clear explanations of what to do in this step, what to do next, and why to do it. Not to mention college students, even junior high school students can understand it.

And the purple spirit liquid was developed by Chen Chuan's ancestor, although the page is only text, the picture is full of sense, as if watching a teaching video.

After reading it, Xu Fan's excited heart surged, like making some physics inventions when he was a child, which was both fresh and novel.

Immediately, Xu Fan said hello to the three roommates, then closed the door of the house, and began to officially try to refine the spiritual liquid without being disturbed by outsiders.

"The first step is to check the integrity and age of the herbs. ”

Xu Fan opened the bag, all the medicinal materials were collected by Wang Biao, and he hadn't had time to look at it yet.

There is a detailed explanation of the medicinal materials of the purple pole spiritual liquid in the alchemy experience, and Xu Fan checked them one by one according to the above instructions.

The completeness is well checked, and it can be discerned from the appearance.

As for the age limit, the experience taught a method to cover the medicinal materials with mana, and through the traces of time in the medicinal materials, you can roughly judge the age of the medicinal materials.

Xu Fan guessed that he didn't know if this method could be applied to antiques, and if it could, it would be a good profit.

"The medicinal materials are basically no problem, the required age of wild ginseng is 50 years, and it is a bit wasteful to use 100 years, but I mentioned in my experience that the higher the year of the main medicine, the greater the chance of success. Well, so be it. ”

Xu Fan pondered, and then the second step.

"The second step is to check the Dan furnace to keep the furnace clean and the tightness of the Dan furnace. ”

Yin Lao Mo had just refined the spirit liquid in the Dan furnace, thinking that there could be no problem with the sealing, the furnace was very clean, only a little faint smell of medicinal herbs.

There are many lines carved on the inner wall of the furnace, which is a formation to assist alchemy, and it has the effect of getting twice the result with half the effort.

Xu Fan nodded with satisfaction.

"The third step, fire control. ”

This step was not mentioned in the alchemy experience, and Xu Fan joined this step himself, mainly to prepare for adjusting the gas stove.

According to the experience of immortal cultivators using fire control techniques, refining the spiritual liquid requires at least the cultivation in the later stage of foundation building, and the firepower is clearly measured.

The maximum amount of energy that a match can emit is one degree.

In the process of refining, it is adjusted from time to time: 1,000 degrees, 2,000 degrees, 5,000 degrees, 300 degrees......

The meaning of 5,000 degrees here does not refer to temperature, but to the maximum energy when 5,000 matches are burned at the same time.

If it is really a temperature of 5,000 degrees, steel can be turned into boiling water, and these herbs on the earth cannot withstand it.

"Da"

Xu Fan turned on the gas stove and stared at the flames, feeling the energy on it.

"No, the fire is too small, and it is estimated that it is equivalent to two or three thousand degrees at most, which is twice as bad as five thousand degrees. ”

Two or three thousand degrees is equivalent to two or three thousand matches burning at the same time, and the energy released is actually quite considerable.

Xu Fan frowned slightly, this gas stove was specially selected by Wen Ziyang, and it was more violent than the ordinary household gas stoves on the market.

Where to buy a better gas stove?

Do you want to go to Old Demon Yin's villa to get it again? I don't know if the gas stove is suitable, after all, the spiritual liquid is different, and the refining method will be different.

Suddenly, Xu Fan had an idea, took out his mobile phone, and opened Taoxian Bao, an app specially used by immortal cultivators.

I remember seeing something similar on it before.

As for why the medicinal materials for refining the spiritual liquid were not bought on it, it was because all the medicinal materials like wild ginseng needed points to exchange, and Xu Fan had no points at all so far.

Fingers slid the screen, and valuable things swiped in front of him, and after a while, Xu Fan's fingers flickered, and his eyes locked on a picture.

"Bingo!"

In the picture, a pure black gas stove is blazing in the air holes.

Below the picture is the text introduction.

"The special gas stove for alchemy, built by Ming Hao Zhenren, can fine-tune the firepower, support various energy conversions such as natural gas, gas, electricity, mana, etc., and can support the release of 20,000 degrees of energy in an instant. ”

Xu Fan's eyes lit up, then noticed the price, and secretly smacked his tongue.

"Two million units, that's not cheap. ”

Xu Fan hesitated for a while, and noticed that there were more than 999+ sales records, and the comments were basically all praise.

"The gas stove was nice and good value for money. ”

"Kindly remind those who want to use gas, prepare a few more cans of gas!"

"The second time I bought it, I accidentally blew it up during the last alchemy, so I recommend joining the defensive formation. ”

......

Exploded during alchemy, this comment attracted Xu Fan's attention.

The novice alchemy experience in the precautions particularly emphasized the fryer, the reason is that the air pressure in the Dan furnace is unstable, once the fryer, the medicine will be completely destroyed, and the heavy will affect the surroundings.

Fortunately, the ordinary spiritual liquid in the condensation period does not have to worry too much about the danger of the fryer.

"Isn't it just two million, buy it!"

Xu Fan gritted his teeth, directly bound the bank card, and the payment was successful.

At this moment, he felt refreshed, he had never bought such an expensive thing in his life.

Just after the order was successful, the store automatically replied to the message: "Dear, the goods will be delivered immediately, don't rush, the domestic will arrive the next day." ”

It will arrive tomorrow, Xu Fan is not in a hurry.

He put the Dan stove on the gas stove, brought a basin of water from the kitchen and poured it in, boiled the water first, and tried the feeling of alchemy.

Then I controlled the flame size of the gas stove and felt the change in energy.

It is worthy of a special alchemy furnace, boiling water is called a fast, and after a while, it begins to boil, making a roaring humming sound in the sealed Dan furnace.

Xu Fan thought it was interesting, and suddenly remembered his own samadhi true fire, wondering if it could be used to increase the firepower.

So he consumed a lot of mana to condense a small flame and control it to fly to the bottom of the Dan furnace.

"Boom!!"

A loud bang was like thunder on the ground, and the second-story building trembled a few times, and at the same time woke up the three roommates who were cultivating in the courtyard.

The surrounding residents were also shocked.

Xi Jie came out the fastest, jumped from the second floor with a whoosh, and opened the door of the 'alchemy room' on the first floor regardless of the danger, and a heat wave of water mist condensed came to his face.

"Brother Fan, are you alright?"

"Ahem, no, it's okay, Dan Furnace, where did Dan Furnace go?"

Xu Fan got up from the corner, and just now he saw that it was wrong, he rolled on a donkey, hid by the wall and lay on the ground, avoiding the danger of being burned directly by the heat wave.

"Is that the one?"

Xi Jie pointed to the roof, which was stuck in the crumbling Dan furnace on the top plate.

Subsequently, Li Yunlong and Wen Ziyang also came downstairs, and they all felt scared when they heard the reason, and repeatedly reminded Xu Fan to be careful and not to mess around.

Fortunately, there was no problem with the Dan furnace, and Xu Fan breathed a sigh of relief.
