Jiang Heng, who was honest, was also stunned.

Is that okay?

True gas turns into fire, that's a legendary skill.

"I remember." Shen Zhenglong seemed to think of something at this time, and suddenly said: "Back then, the master of the elder had used to use this hand of true qi to turn fire, which is also an ability that only an alchemist can do. ”

"Then why wouldn't Deacon Liu do this?" Jiang Heng couldn't help but ask.

"Not every alchemist can really turn into fire, only a few extremely talented alchemists can." Shen Zhenglong explained.

The corners of Liu An's mouth twitched, and his face was a little ugly.

That is to say, his talent is not as good as Liu Fan?

But he also had to admit that he was really envious.

True Qi Turning Fire is definitely an ability that all alchemists dream of, but if they want True Qi to turn into fire, they must have extremely high talent and understanding.

In this regard, he has already lost a lot to Liu Fan.

"Is there any difference between True Gasification Fire and ordinary flames?" Long Yuntian couldn't help but ask.

This has touched on his knowledge blind spot.

Shen Zhenglong said in a deep voice: "If you want to melt the medicinal materials in the medicine pot, the temperature can reach about 1,000 degrees, which is also the more common temperature of ordinary stoves, if you want to speed up the melting speed of the medicinal materials, you can use true gas to increase the temperature of the furnace, so in terms of temperature, the real gas fire is not much different from the furnace, the biggest difference between the two is flexibility." ”

"Flexibility?" Long Yuntian and the others were a little puzzled.

"That's right." Shen Zhenglong nodded: "In the early stage of refining the elixir, high temperatures are often needed in order to melt the medicinal materials, but in the later stage, after the medicinal materials are melted into a thick liquid, if you want the elixir to take shape, you must quickly cool down, and the furnace needs to be manually adjusted in this regard, which will affect the quality of the elixir to a certain extent, but there is no such trouble when the true gas turns into fire, because they can adjust the temperature of the flame as they like, which can either instantly rise to the highest temperature or instantly drop to the lowest temperature." ”

"Understood." Long Yuntian suddenly realized: "There is no risk of true qi turning fire into alchemy, but if you use furnace fire to refine pills, there will be a possibility of missing to a certain extent." ”

"Yes, not only that, but the best quality pills are often refined by true qi and fire." Shen Zhenglong nodded.

Liu Fan heard what Shen Zhenglong said and smiled secretly.

It seems that the vice president's knowledge of true qi and fire is not enough.

True gas turns fire into even greater use.

"And there is another point, true gas and fire are more dominant." Long Poria looked at the flames in Liu Fan's palm, and his eyes lit up.

"What?" Jiang Heng asked subconsciously.

"Don't you think it's cool to have this hand really gassing into fire?" Long Poria's eyes were full of gold stars, and she was envious.

"Who's to say it isn't?" Shen Zhenglong said with emotion.

"Your Jiangsu and Zhejiang Medical Daoist Association has really made a lot of money this time." Long Yuntian said with sincere envy.

"Hey, hey." Shen Zhenglong also smiled proudly.

Jiang Heng was also quite excited.

No wonder the vice president treated Liu Fan so favorably, and now it seems that he is really far-sighted.

Liu Fan was refining the elixir without distraction, his expression was very focused, and he didn't care about the amazed gazes of others.

Liu An's expression at this time was also much more solemn, and he didn't dare to underestimate Liu Fan anymore, and he was also engrossed in refining the elixir.

His biggest advantage now is experience.

After all, talent and experience are two different things, no matter how talented a person is, as long as he lacks experience, it is equally impossible to refine a high-quality elixir.

And he has been alchemy for many years and has extremely rich experience, how can he be worse than Liu Fan?

His advantage in experience more than makes up for his lack of talent.

Shen Zhenglong and the others didn't dare to disturb, and stayed quietly aside, waiting for the final result.

Soon, the medicinal materials in Liu Fan's medicine tripod also slowly melted, turning into an extremely thick mass of juice, releasing a strange medicinal fragrance.

At the same time, the medicinal materials in Liu An's medicine tripod also began to melt.

Smelling this peculiar medicinal fragrance, Shen Zhenglong couldn't help but sniff and said with a smile: "The medicinal materials in their medicine tripod have begun to melt, and the next step is the process of removing the impurities in it." ”

Although he is not an alchemist, he still has some understanding of the basic process of alchemy.

"How do you get rid of impurities?" Long Yuntian asked curiously.

"The spiritual power of the alchemists is much stronger than ours, and at this time, they will release their spiritual power into the medicine tripod, and then separate the impurities with their powerful spiritual power, and the remaining juice will be all essence." Shen Zhenglong briefly introduced: "And this step also determines the quality of the elixir, whoever purifies it better, the quality of the elixir will be higher." ”

Liu An obviously knew this, and he didn't dare to be careless, and his mind was more concentrated.

After a minute or so, he manually lowered the temperature of the stove.

"Deacon Liu is starting to cool down the potions." Shen Zhenglong said.

"So fast?" Long Poria said in surprise.

"After all, he is an alchemist who has been alchemizing for many years, and he must be more experienced." Jiang Heng explained: "In this regard, Liu Fan may suffer a loss. ”

At this moment, the temperature of the flame in Liu Fan's hand was still very high, and it was obviously still purifying.

Liu An pouted secretly.

This kid is still too young and seriously inexperienced.

Immediately afterwards, Liu An gently slapped the medicine pod in the air, and after a light sound, a pill flew out of the medicine pod and fell into Liu An's palm.

Everyone hurried over to take a look.

This pill is about the size of an adult's thumb, and its whole body is milky white, constantly exuding a faint medicinal fragrance.

"This pill is of good quality, with only a very small amount of impurities on the surface." Shen Zhenglong looked at it carefully and commented.

Everyone could also see that this elixir was basically white and flawless, with only a small brown spot on the surface, about the size of fine sand, but almost negligible.

Liu An smiled very proudly.

"This pill is indeed of good quality, it can be called the top grade." At this moment, a flat voice suddenly came from behind them.

Everyone turned their heads and saw an old man standing behind them.

"President?" Shen Zhenglong exclaimed in surprise when he saw this person.

Jiang Heng and the others also hurriedly bowed down to show respect.

Long Yuntian and Long Lingling didn't dare to slack off, and hurriedly bowed down.

This is the president of the Jiangsu and Zhejiang Medical Taoist Association, and he is a super big man who stomps his feet casually, and the entire Jiangsu and Zhejiang Province will tremble.

Even the high-level leaders of the four major families in Hangzhou have to bow their heads in front of each other and dare not be presumptuous.

"President, why did you suddenly get out of the customs?" Shen Zhenglong couldn't help but ask.

"I smelled the smell of medicine coming from here, and I guessed that it wasn't easy, so I came over to take a look." Huo Jingzhi said with a light smile.

"Isn't it normal to have medicinal fragrances, why are things not simple?" Long Poria asked curiously, "How did the elder judge it?" ”

"Of course, it's not strange that there is a medicinal fragrance, but if the medicinal fragrance comes from this secret room, it will be different." Huo Jingzhi explained with a smile.

When everyone heard this, it was instantly clear.

Who would be alchemy in the secret room.

"Looking at the situation of this pill, although there are still impurities, it is controlled within one percent, which is enough to be called a top-grade pill." Huo Jingzhi commented again.

Shen Zhenglong also added: "If the impurities are controlled between 1 percent and 5 percent, it is a medium-grade pill, and if the impurities are between 5% and 10%, it is a low-grade pill, and the higher the quality of the pill, the better the efficacy." ”

Long Yuntian nodded secretly.

Among the few pills owned by their Long family, there was only one top-grade pill, and the rest were all medium-grade pills.

"Deacon Liu's alchemy level has improved a lot." Huo Jingzhi exclaimed.

"The president praised it." Deacon Liu was ecstatic in his heart and said very modestly.

To receive a word of praise from the elders is an absolute honor of a lifetime.
