The stall owner of the "chalcedony pill" is a young man in his twenties and thirties, and his hair is held in a bun by a delicate hosta, and he is holding his arms around and waiting for the buyer to come to the door.

Tang Mian hesitated for a moment, then stepped forward, picked up a small bottle with one hand, opened the cap and sniffed it pretentiously, and asked:

"What is the effect of this pill?"

The stall owner looked at Tang Mian, squeezed out a smile on his face, and said:

"This pill is called Chalcedony Pill, and its main effect is to help the Qi refining period cultivators to cultivate their cultivation. ”

Tang Mian bowed slightly, and then asked about the price, and when the other party quoted the number, he finally understood why this person's pill could not be sold.

Tang Mian shouted in his heart, a medium-grade spirit stone can be exchanged for a hundred lower-grade spirit stones! The most common healing elixir in the Qi refining period, the Rejuvenation Pill, only needs five spirit stones to buy a bottle, and the price of ordinary intensive cultivation pills is only between ten and twenty yuan per bottle, which shows that the price of this "chalcedony pill" is outrageous.

"With such a high price, I'm afraid no one in the Qi Refining Stage can afford it, right?"

Tang Mian pressed the surprise in his heart and said lightly.

The young stall owner shook his head with a smile, and his eyes casually swept over the nearby monks and said:

"These pills I refine are not sold to the poor, the chalcedony pill is a medium-grade pill, the effect is more than ten times that of the lower-grade pill, and it is far safer and milder than the lower-grade pill, so you don't have to worry about going crazy and the like. ”

Tang Mian had to look at this guy again when he heard this, listening to his words, these pills seemed to be refined by himself, which meant that the other party was an alchemist, obediently, this is a talent!

With a wave of his big sleeves, Tang Mian pinched three medium-grade spirit stones in his hand, and said with a smile:

"How do you prove that you're telling the truth?"

The young stall owner raised his eyebrows when he saw the medium-grade spirit stone in Tang Mian's hand, it turned out that Gujing Wubo's face showed a look of surprise, he didn't expect that this rookie with the third layer of qi refining in front of him could take out three medium-grade spirit stones at once.

"Since you have enough spirit stones, why don't you give it a try?"

The stall owner very simply poured out a round pill from the jade bottle, Tang Mian took it in his hand, and a fragrance wafted out from the pill, refreshing people's hearts.

Tang Mian looked at the pill and then at the other party, who looked at him expectantly, as if urging him to take it quickly.

"You can't hurt me, do you?"

Tang Mian was guilty in his heart, and after a moment of silence, he released his divine sense and wrapped the entire pill, after all, it was a matter of life, and he carefully investigated it.

"Don't be so careful, I swear by the demons in my heart, there is no problem with this Dan!"

Seeing Tang Mian's slow appearance, the young stall owner suddenly lost his patience, and simply made a very binding demon oath in the cultivation realm.

Tang Mian didn't expect this alchemist to have such a great temperament, you must know that if the heart demon oath is violated, it is very likely that he will go mad in cultivation, and then become a monster who is not a human or a ghost.

"I believe you!"

Tang Mian gave a thumbs up, and then swallowed the chalcedony pill without hesitation.

As soon as this pill entered his body, it directly turned into a pure and gentle energy into the meridians, this energy not only contains medicinal power, but also has a very high concentration of heaven and earth aura, on the one hand, it assists Tang Mian to broaden the meridians and break the bottleneck, and on the other hand, it increases the condensation and transformation of mana, so that Tang Mian's cultivation of the third layer of refining qi is directly loosened, and this is still the case that he does not actively guide the operation of the exercises.

Good things naturally can't be wasted, Tang Mian immediately ran the Lei Yan Jue Mental Method, incinerated the aura contained in the acupoints in various acupoints into mana, and then pulled the mana to attack some bottlenecks.

For half an hour, Tang Mian stood motionless with his eyes closed, until most of the aura was converted into mana and stored in the dantian, then he slowly opened his eyes, and his eyes were full of surprise.

"Thank you Daoyou for protecting the Dharma for me, I want this Dan. ”

As Tang Mian spoke, he casually handed over the three medium-grade spirit stones.

The young stall owner swept his robe, put away the spirit stone, and then handed over the three bottles of pills, and said with a smile:

"I'm afraid that in two days, Daoyou's cultivation will go to the next level. ”

The two looked at each other and smiled, the deal of the chalcedony pill was completed, and both parties were quite satisfied. The two immediately began to talk, and after introducing themselves, they also became familiar with each other.

"Daoist Chen Li, I have a few bottles of pills that I got by accident, can you identify their efficacy for me?"

Tang Mian didn't forget the few bottles of unknown pills in the storage bag, and when he patted the storage bag, several bottles of pills appeared in front of him.

Seeing that Tang Mian wanted to identify the pill, this young alchemist named Chen Li immediately became interested, carefully took one of the bottles of pills in his hand, opened the lid and smelled it, then poured out a round pill, observed it for a while, and then slowly closed his eyes.

Tang Mian naturally knew that the other party was using his divine sense to investigate, so he stood aside obediently, not daring to disturb.

After a while, Chen Li returned the pill to the jade bottle, and after glancing at Tang Mian with great meaning, he immediately picked up another bottle of pill, this time with an incredible look in his eyes, but he didn't say anything, but picked up the next bottle of pill and carefully identified it.

In less than a stick of incense, Chen Li had identified all the pills, and at this time, his eyes were somewhat strange when he looked at Tang Mian.

Chen Li looked around, and then said to Tang Mian:

"This is the Fire Returning Pill, which is used by the cultivators of the foundation building period who practice the Fire Cultivation Method to refine their cultivation, and it is also used to consolidate the foundation and cultivate the Yuan. ”

"This is the Golden Black Pill, which is quite a good healing medicine, and generally speaking, only a foundation building monk can afford to use it. ”

While speaking, Chen Li had been observing Tang Mian's reaction, and the latter's performance was quite calm and restrained.

Of course, Tang Mian knew that these pills were all at the foundation building level, he just wanted to know their specific effects, and he would be able to use them sooner or later when he broke through to the foundation building stage.

Chen Li picked up the last bottle of elixir, licked his lips, and said:

"This last bottle is one of the Tsukidan that needs to be taken at the peak of the Qi Refining Layer—the Qingling Pill. ”
