Yao Shan just glanced at these two Xuan-level five-grade Ding furnaces, and he already knew them in his heart, and when he saw that Ye Dong was watching carefully, he simply explained to him: "Although the grade of the Ding furnace is related to the materials they are made of, what is more important is the flame temperature they can withstand and the level of elixir that they can refine. ”

"Xuan-level five-grade Ding furnace, the limit of the flame that can withstand is the Xuan-level five-grade flame, beyond the fifth grade, the Ding furnace will be melted by the flame. ”

Hearing this, Ye Dong immediately couldn't help but ask: "Then my Purple Flame Dragon Fire is a second-grade spirit-level Ding Furnace, doesn't it have to be a Spirit-level second-grade Ding Furnace?"

"You can adjust the temperature of the flame, unless you want to refine medicinal herbs with extremely high melting points, otherwise, where do you need to adjust the temperature to that high. ”

Flame temperature adjustment, Ye Dong has never tried it before, but it should be possible to think about it.

"As for the elixir, there is also a grade differentiation, which is divided into nine grades, but among each product, according to the different medicinal effects, it is divided into four grades of the lower, middle and upper poles, so there are thirty-six grades in total, and the same kind of pill, for example, the most commonly used Qi Tonifying Pill is the lowest grade of the first-grade pill, but according to its different efficacy, there is a difference between a superior grade and a inferior grade. ”

"A first-grade inferior Qi Replenishing Pill can only restore one-tenth of your aura at most, while a first-grade grade can restore nearly half of your aura. ”

"In short, the higher the grade of the Ding Furnace, the higher the efficacy of the pills that can be refined, like this Xuan-level Five-Rank Ding Furnace, theoretically the highest can be refined out of the Five-Rank Pills, but any alchemist who can refine such a high-grade Pill as the Five Grades will use a more advanced Ding Furnace as much as possible. ”

After Yao Shan's explanation, Ye Dong finally had a general understanding of the knowledge of Ding Furnace.

Seeing that the guy hadn't come back yet, Ye Dong whispered: "Old Yao, the elixir you said that can delay toxicity is a fourth-grade pill, then let's buy a Xuan-level fourth-grade Ding furnace in a while!"

Yao Shan smiled slightly and said, "The Xuan-level four-grade Ding Furnace also costs four or five thousand taels of silver!"

Ye Dong was stunned and said: "Does that mean that the silver on my body can only buy a Xuan-level first-grade Ding furnace." ”

"Almost!"

Ye Dong smiled bitterly and said: "Then why don't you buy a Xuan-level product first, and use it to practice your hands, and then buy a better Ding furnace after I find a way to save enough silver!"

"Don't worry, I naturally have a way!"

"Do you have the money to lend me?"

Yao Shan Ha said with a smile: "Young master, I am only in the soul state now, where can I hold things, besides, after I stepped into the realm of the earth, I have never used silver again, don't worry, I will have money in a while." ”

Obviously, Yao Shan intended to sell it, and Ye Dong had no other way but to see what way Yao Shan could get money.

At this time, the guy had already walked in with two cups of hot tea, and said with a smile: "Are you two optimistic? Don't worry, take your time, let's take a sip of tea first!"

Yao Shan didn't take his teacup at all, but frowned and said, "Man, why do I think that your two Ding Furnaces are not Xuan-level five grades at all!"

Ye Dong thought to himself, could this be Yao Shan's so-called method, deliberately finding fault?

The guy put the teacup on the table without any annoyance and said: "Master, our store has been open for many years, the reputation must be guaranteed, and it will definitely not be shoddy. ”

Yao Shan said coldly: "Can the seller still say that his things are not good, so let's do it, I want to inspect the goods!"

The guy pointed to the two Ding furnaces and said, "Master, the Ding furnace is here, you can look at it casually." ”

"Let's see what is good and bad, let's try to use the Ding Furnace to refine medicine!"

As soon as he said this, Ye Dong and his buddy were stunned at the same time!

The guy rubbed his ears vigorously and said, "Master, you mean, you want to refine medicine on the spot here?"

"Well, if the effect of the refined pill is good, then we will buy this Ding furnace, if the effect of the medicine is not right, hum!"

You must know that refining medicine is a delicate job, but all alchemists will have a special Dan room, and the Dan room is not an ordinary room, but carefully built, with special requirements for ventilation, temperature, and humidity.

And when refining medicine, it is also taboo to be disturbed, so if the general alchemist wants to refine medicine, it is equivalent to a practitioner's retreat, and there are people outside the Dan room to protect the Dharma, in short, the requirements are more cumbersome.

And like Yao Shan, he directly wanted to do alchemy on the spot in this secret room, which naturally frightened both the guy and Ye Dong.

Yao Shan's eyes widened and said, "What's the matter? Could it be that your Ding furnace is really a defective product, so you don't dare to let me refine medicine here?"

"No, no, no......" The guy didn't know how to answer, the store has opened until now, and for so many years, he has never encountered this situation!

"Master, I'm just a little guy, I can't be the master, so let's go, our shopkeeper is out of the house, and I'll come back soon, it's better to wait for him to come back, I asked him later, okay?"

"And when will your shopkeeper come back?"

"Quick, at most half a stick of incense!"

"Okay, then you go outside and wait, we have to discuss something, and when your shopkeeper comes back, notify me immediately!"

"Okay, okay, I'll go!"

As long as Yao Shan was not here to refine medicine on the spot, the guy naturally agreed to everything and hurriedly ran out.

After the guy left, Ye Dong whispered, "Old Yao, don't you really want to refine medicine here!"

Yao Shan nodded and said, "Yes, if you don't refine the medicine, where will the money come from?"

When the words fell, a flame had already appeared on Yao Shan's palm, it was his dust body, Xuanyang Flame!

Ye Dong's eyes were about to pop out, and he whispered in surprise: "Old Yao, what are you doing?

Yao Shan didn't answer at all, with a slight flick of his wrist, the flame automatically left his palm and floated to the empty space below the snake ding, and suddenly, in an instant, the temperature in the room immediately rose.

At the same time, Yao Shan also stretched out his hand to Ye Dongdao: "Give me the medicinal herbs you bought!"

Ye Dongzhen didn't expect Yao Shan to say that refining medicine would refine medicine, but since it had already begun, he naturally couldn't stop it anymore, so he hurriedly took out the three medicinal materials that he had bought in Yifeng City and handed them over.

Yao Shan didn't answer, but waved his hand lightly without looking, and the three medicinal materials were thrown directly into the mouth of the ding, and then the other hand was gently pressed in the air, and he heard the sound of "Kata", and the mouth of the snake ding, that is, the mouth of the snake, was actually closed!

Ye Dong looked surprised, he didn't expect that there was a mechanism on the ding, he turned his head to look at Yao Shan, ready to ask what was going on, but this look made him startled again.

I saw that Yao Shan was carrying his hands behind his back at this time, his eyes were slightly closed, and he didn't look at the Ding Furnace in front of him at all, looking at his appearance, where it seemed that he was refining medicine, but as if he was thinking about a problem.

Ye Dong's mind couldn't help but have big doubts, this is refining medicine?
