Luo Tian watched quietly from the side, his eyes shining.

He could feel that in the Dan furnace, the aura that had already begun to go berserk gradually subsided under the few beats of the master, and the burnt smell slowly faded.

"Sky Eye, Scan. ”

The mind gave the order to the eye of heaven.

In the next moment, in Luo Tian's mind, the scene in front of him changed.

Mentor Donghua's seemingly ordinary slapping actually contained a special meaning, and there were Dao fluctuations that formed runes that invaded the Dan furnace.

With the invasion of these runes, the violent spiritual power fluctuations in the Dan furnace slowly subsided.

Luo Tian looked at it for a while, only to feel that his head was dizzy, and the scene in his mind was distorted and blurred for a while, and slowly disappeared.

"It's too much mental energy. ”

Luo Tian rubbed his temples, and his heart moved.

Just now in the phantom array, he seemed to have consumed a lot of spiritual power, and at this moment, observing the master's alchemy, he couldn't support it for a while.

"It's a loss, it's a big loss!"

At this time, Mentor Donghua had already lifted the lid of the Dan furnace and screamed in pain in his mouth.

Luo Tian was a little puzzled, the situation that Tianyan had just shown, this Dan should have been practiced, but looking at the pained expression on the face of the mentor, this Dan seemed to have been refined.

Just when Luo Tian doubted the results of the Tianyan scan, Mentor Donghua had already taken out the Dan and put it into a small jade bottle.

There are a total of three rune pills, each of which is the size of a dragon's eye, and the whole body is blood red, each with runes on it, and the aura is dense.

"Boy, give. ”

After the Donghua tutor finished cleaning up, he handed the jade bottle to Luo Tian.

"Mentor, this?"

Luo Tian was slightly stunned, and did not reach out to pick it up.

"If you take it, you can take it, it was originally for you. ”

Mentor Donghua glared at Luo Tian and stuffed the jade bottle.

"Thank you, mentor. ”

Luo Tian was a little moved, he had been in the school for so many days, of course he knew the preciousness of Fu Dan, not to mention, looking at the appearance of this Fu Dan, it was absolutely extraordinary.

"The common problem of most rookie talisman apprentices is that the physical body is generally one level weaker than the spiritual power, and you kid is no exception, the spiritual power should barely reach the standard of an intermediate talisman apprentice, but this physical body is a bit weak. ”

Tutor Donghua looked Luo Tian up and down and said.

The mentor's eyes were like torches. ”

Luo Tian smiled slightly, and did not deny it.

His physical body is indeed one level weaker than his spiritual power, but this is only a temporary situation, with the improvement of the demon bloodline, the physical body will gradually increase, until it is on par with spiritual power.

"Less sycophancy. ”

Tutor Donghua rolled his eyes, pointed to the medicine bottle in Luo Tian's hand, and said, "This pill is called the Washing Pill, which can wash the marrow and cut hair, from the inside out, it is a high-grade Fu Pill that strengthens the body." ”

"Dare to ask the mentor, how many products are there in this Fu Dan?"

Luo Tian asked.

"It's not like that, Fu Dan, it's divided according to the strength of the applicators......

Tutor Donghua popularized the knowledge of pills to Luo Tian.

It turns out that Fu Dan is divided into grades according to the strength of the applicable people, for example, the Fu Dan suitable for the apprentice of the Fu Master is called the apprentice level, and the Fu Dan suitable for the Fu Fan Master is called the Fu Fan level, and so on.

And each level of elixir, according to the different purity of the essence, there are inferior, ordinary and imported.

The judging criterion is the purity of the elixir.

It is a medicine that is three points poisonous, and Fu Dan is the same.

In Fu Dan, the toxic substances reach more than 50%, and its purity is below 5 degrees, which is inferior Fu Dan.

The purity of the essence is above five degrees and below seven degrees, which is an ordinary rune pill.

If the purity is more than seven degrees, it is the entry of Fu Dan.

The Fu Dan can be subdivided into genuine products, earth products and heavenly products.

In addition to the purity, there is also an intuitive way to judge the quality of Fu Dan, which is Danwen.

Dan pattern, in fact, is a combination of runes, and the name of Fu Dan also comes from this.

One to three Dan patterns are genuine Fu Dan, and the purity is seven to eight degrees.

Four to six Dan patterns, Nai Di Fu Dan, eight to nine degrees of purity.

Above the earth, it is the heavenly product!

Tianpin Fu Dan, the surface of the Dan pattern seven to nine ways, the purity of the purity beyond nine degrees, infinitely close to ten degrees!

Nine is the extreme, but it is rumored that above the heavenly product, there is also a product, which is called a divine product, ten ways of Danwen, ten degrees of purity! Of course, this is just a legend, no one has ever seen it.

"It's completely different from my previous pharma. ”

After hearing this, Luo Tian sighed in his heart, looked at the Fu Dan in his hand, and said, "Mentor, then this Pulp Cleansing Pill and Meditation Pill are apprentice-level products?"

"What do you mean by entering the product, the old man is an alchemy master, and all the things he refines are the entry runes!"

When Tutor Donghua heard this, he jumped to his feet.

"Alchemy Grandmaster!"

When Luo Tian heard this, his expression lit up.

Just now, the tutor said the grade of the alchemy talisman master.

In the Tiannan Federation, alchemy runes have different titles according to the grade of runes refined.

Inferior Fu Dan, generally people who have been exposed to Fu Dan training can refine it, and there is no special title.

Those who refine ordinary runes can be called alchemists.

And those who refine the real rune pill can be called an alchemist!

Refining the earth-grade rune pill is a master of alchemy!

Above, there is the alchemy master, who can refine the Heavenly Fu Dan!

Of course, before these titles, there is also a prefix, and that is the rank.

For example, apprentice-level alchemists, metamorphosis level alchemists, Yongquan-level alchemists, etc.

These titles are subject to the professional examination of the Federation, and after obtaining the title, you can enjoy federal allowances and enjoy various privileges, which is a distinguished profession.

Thinking of this, Luo Tian's eyes lit up, he didn't expect that his mentor was actually an alchemy master, so it seemed that the Fu Dan in his hand was not all heavenly products!

Thinking like this, Luo Tian hurriedly took out the medicine bottle and observed.

"You kid thinks too much, you think that the Heavenly Grade Fu Dan is so easy to refine, even if it is an alchemy master, refining one or two in the ten furnaces is already full of luck. ”

Seeing this, Mentor Donghua rolled his eyes, and then his face ached, and said: "Lao Tzu is originally a mortal-level alchemy master, refining these apprentice-level Fu Dan, the probability of becoming a heavenly product is quite high. ”

"Hmph, just blame you kid, don't come early or late, but come at this time, and make such a play, after learning all the basic courses in ten days, Lao Tzu was startled by you, forgot the time, a good furnace of heavenly Fu Dan, turned into a ...... of earth"

Tutor Donghua seemed to have turned on the fragmented thought mode, and kept muttering.

Luo Tian could only smile, but he was slightly excited in his heart.

On this trip, I not only learned about the rank of Fu Dan and Alchemy Fu Master, but also gained two kinds of Fu Dan.

He saw that on the ten meditation pills, there are eight Dan patterns, which are heavenly products!

Although the marrow washing pill is not a heavenly product, the Dan pattern of each one has reached six paths.

"Boy, remember, it's okay to say that the Meditation Pill is good to say, once the heart is tyrannical, there is no restriction on taking it, but the Cleansing Pill, although it is only more than one percent toxic, but the interval between taking it cannot be less than one month. ”

After Tutor Donghua muttered, he did not forget to instruct, "Otherwise, the accumulation of toxicity in the body will damage the physical body, and the drug resistance will be enhanced, affecting the effect of Fu Dan." ”

"Yes, Mentor, I made a note of it. ”

Luo Tian said gratefully.

"Dan Dao is broad and profound, and the old man can't teach you much, the key is to look at the individual's understanding, well, from today onwards, every night, when you come here, the old man will teach you. ”

Thinking of Luo Tian's demonic understanding, Tutor Donghua plans to directly teach all the ideas of the teaching, saving trouble and worry.

"Thank you, mentor. ”

Luo Tian was excited in his heart and bowed.

With such a generous treatment, the disciples are just like that.
