Han Fei hadn't noticed the importance of the Ding Furnace to the alchemist before.

Now that I have been refining the pill for more than a year, I have also consulted a lot of information and classics about alchemy, and I know the importance of the Ding furnace to the alchemist, a good Dan Ding can not only save the alchemist's mana consumption, but also improve the pill production rate and quality.

Sometimes it can even be used as a magic weapon, whether it is offensive or defensive, its power is also good.

After studying for a while, Han Fei still didn't see the origin of the material of this Ding Furnace, he only knew that this Ding had gone through many years and had been abandoned for a long time before it became like this.

"Can this tripod be cheaper, this tripod is still a little less, it is a defective product. ”

"If Daoist friends really like this tripod, then it is ten spirit stones cheaper. ”

Looking at this young man's jerky and timid appearance, Han Fei couldn't bear to continue to bargain, the current Han Fei was different from when he was in the Service Palace, and more than a hundred lower grade spirit stones were only two pills.

Immediately, Han Fei handed over the spirit stone, put away Xiao Ding, and continued to wander to other places.

At this time, most of Han Fei's attention was still on the jade slips, especially the jade slips that looked quaint, Han Fei had already bought two or three jade slips before, and the upper two of them were some cultivation experiences and some knowledge of alchemy refining tools.

On the third jade slip was a Dan Fang, which recorded the materials and refining techniques very completely, but Han Fei couldn't help but breathe a sigh of relief after reading it.

This Dan Fang is considered an ancient Dan Fang, and most of the materials on it are unknown to Han Fei, but Han Fei bought it after only selling ten spirit stones.

Suddenly, Han Fei's heart throbbed, making him stop unconsciously.

What made his heart palpitate was a strange aura, very faint, but it made him feel very real, and when he turned his head to see the thing that emitted the breath, his heart was even more horrified.

A cyan oval stone, almost indistinguishable from ordinary pebbles.

Han Fei's divine sense swept it several times, and there was no abnormality, not even the breath of a certain spiritual object, let alone some unknown spiritual ore material, and Han Fei also noticed at this time that no one who came and went around him found an abnormality like himself.

This was too weird, and after thinking about it for a while, Han Fei still felt that he wanted to go over and take a look.

"Fellow Daoist, what is this stone?" Han Fei asked, pointing to the bluestone.

The stall was set up by an old man at the ninth level of Qi refining, this person had a thin body with sharp-beaked monkey cheeks, but he was a little rickety, with a wisp of goatee, and his appearance was a little funny.

"This fellow Daoist, you really have a vision, this thing is a green stone, which is extremely precious, but it is an excellent material for refining spiritual weapons, and even some Jindan powerhouses can refine magic weapons, this thing can play an auxiliary role. ”

The old man's expression and eyes were extremely sincere, and he described it even more clearly, explaining the origin of the blue Xuanshi and how he obtained it very clearly, and it was reasonable, if it weren't for Han Fei's refining of Xuantie and studying a lot of spiritual ore materials, he would almost believe the old man's words.

This person must have seen that Han Fei was young, and his cultivation was not low, when he was a child of some sect or family.

Before Han Fei could ask about the price, the old man talked endlessly for a long time.

"How many spirit stones is this?" Finally, when the old man finished speaking, Han Fei had the opportunity to ask the price.

"I see that Daoyou and the old man are quite fateful, so let's do it, how about a price of fifteen hundred spirit stones?" When the old man said the price, he still had an expression of reluctance on his face, and his performance was extremely realistic.

Hearing this, Han Fei really stopped talking, and turned around and left directly.

Who knew that the old man hurriedly took a few steps forward, directly grabbed Han Fei's arm, and then said, "Fellow Daoist, don't be in a hurry to leave, we can discuss the price again." ”

The old man's strength was not small, and Han Fei couldn't break free of the other party's hand for a while.

"Fellow Daoist, please let go, if I don't leave, let's discuss it again. ”

Seeing this, the old man let go of the hand that grabbed Han Fei's arm, and then squinted his eyes and said, "Actually, the old man just wanted to test Daoyou just now, but he didn't think that Daoyou was such an anxious person, which can be regarded as an old man's miscalculation." ”

"It's not a secret, I just think that this thing doesn't have any aura emitted, and it can appear here, so I'm just curious to come and take a look, I'm really not interested in things, or I'll look at other things. ”

Hearing Han Fei say this, the old man's face suddenly turned ugly, and he watched Han Fei touch this and knock that on his stall, and sometimes took out a jade slip and put it on his forehead to check.

After a while, when Han Fei was checking a jade slip, he was not only shocked in his heart.

This jade slip actually recorded an ancient exercise called "Astounding Divine Decision", which was an exercise for cultivating divine sense, and what surprised Han Fei even more was that cultivating this exercise required the qualifications of the five elements of spiritual roots, which was simply tailor-made for himself.

However, there are only three levels of this exercise, and the requirement for cultivating the first level is also to cultivate in order to reach the consummation of the Qi refining period before it can be cultivated.

The fact that such a good exercise would appear in such a place made Han Fei feel inexplicable, and then he thought about it and seemed to understand something, thinking that a person like himself who had all the five elements spirit roots could be said to be even rarer than people with heavenly spirit roots and different spirit roots.

Moreover, with such qualifications, I am afraid that it is extremely difficult to cultivate to the late stage of qi refining, let alone the great consummation of qi refining, and even the bottleneck of this middle stage of my current situation is difficult to overcome, let alone in the future?

It is not surprising, then, that this exercise has been abandoned, and that it is really useless to ordinary monks.

After looking at the overview of the exercises for a while, Han Fei put the jade slip back and then picked up another jade slip and looked at it.

The old man saw that Han Fei was checking the jade slips so seriously, and then he stopped making a sound, waiting for Han Fei to finish reading these jade slips.

After looking at the few jade slips on the old man's stall, Han Fei was even more shocked in his heart, because several of them were ancient jade slips, and some recorded some precious materials, demon beasts, and even pills from the ancient period.

Some recorded some anecdotes in ancient times, and some of the cultivation experiences of ancient monks.

What interests Han Fei the most is that in addition to the "Shocking Divine Decision", there is also a resting exercise, and the cultivation requirements are almost the same as that of the Shocking Divine Decision. And its effect is extremely powerful, and it seems to be a match for that amazing thing.

Because one of the keys to cultivating this technique is to enter the threshold of the first layer of the Divine Determination before you can practice this secret technique, which is called "Hidden Divine Decision".

After Han Fei finished reading these jade slips, he randomly picked out three or five of them, and then said: "I want these jade slips, you can make a price, explain in advance, if you ask for a price again, I will still turn around and leave." ”

Suddenly, the old man's words came to his lips and swallowed them back again.
