After saying this, the old man in brocade turned around and entered the house, and closed the door with his backhand. A group of people full of anticipation outside stared at each other, not knowing what this old man was doing.

Lu Qiming was about to follow, but he didn't expect that he was also locked outside, and touched his nose a little embarrassedly, just in time to meet Song Ping'an's gaze, which made her laugh.

Fortunately, this time it's really not a dumb mystery. Just as people were hesitating to leave, the door opened again - the old man in brocade walked out with one hand holding a medicine tripod.

It's not easy. This pod is a little different from what people usually see, it is half a person high, narrow at the top and wide at the bottom, vaguely like a huge gourd, but the whole body is a black mass, like some kind of metal, and the concave and convex surface is faintly shining in the light. Although the onlookers couldn't understand it, they also obviously felt that this medicine tripod must be extremely heavy, and the old man in brocade clothes lifted his weight like a light weight, as if he was only holding a cup of tea.

Many onlookers' eyes lit up as soon as they "sighed", and they all rubbed their hands, and the eyes that looked at the old man in brocade clothes were immediately even more different - the people in the twilight are like this, the martial arts are real, and they have a romantic longing for "adventures". As soon as the old man showed his hand, their enthusiasm was immediately ignited, and they couldn't wait to pounce on the apprentice on the spot, and perform a heroic hymn to the counterattack that they were valued by the peerless powerhouse.

The old man in brocade did not move, and with a slight push, the black medicine tripod fell in front of Lu Qiming with a "bang". Lu Qiming looked up and down at the gourd-shaped medicine pod, thought of the ancient book before, and said secretly: "No......"

His bad premonition came true at once. I only heard the unwavering voice of the old man in brocade sound: "The second question, alchemy." ”

A thin piece of paper floated into Lu Qiming's hand, and he quickly took a cursory look at it, and his face was a little difficult to look at.

"Alchemy, what is alchemy?" the crowd commented.

The old man in brocade saw that Lu Qiming had not moved for a long time, frowned and added: "It is to take a step further on the basis of the potion you know, and condense it into a round pill, just like this-" He flicked his fingers and took out a pill the size of a fingernail - but unfortunately this so-called pill is earthy yellow and has no fragrance, and it looks unsurprising.

People were stunned, looking at the old man in brocade with a serious face, and seeing Lu Qiming's embarrassed face, they finally realized that this old man was not joking. People's expressions changed from surprise, questioning, to disappointment and anger, and the noise exploded as soon as it was "whoa".

"Damn, I heard you right, it's more powerful than a potion? How is it possible? This old man is not stupid?"

"It's also alchemy! Lao Tzu has never even seen a living alchemist in his life!"

"I walked away, and I still wanted to find him to apprentice, but I didn't think that he was a ...... with a sick brain."

"Alas, it's really boring, and it turns out to be like this in the end......"

"What kind of elixir, hehe, it won't be made by him himself, right?"

"Speaking of which, listen to me tell you, the taste of drinking that activating potion last time was really refreshing......"

", I've heard you show off eight hundred times!"

......

The elixir that the old man disdained in his mouth had a supreme position in the hearts of the people here. Medicinal herbs can be made into all kinds of precious potions through the hands of alchemists, not only the medicinal effect is enhanced, but also more miraculous effects, and the side effects are extremely small - but unfortunately the price is also extremely high, and most of the potions are not affordable for these ordinary martial cultivators.

The old man in brocade's face was completely gloomy, and he couldn't bear anyone's disregard for the supreme "Danshu" in his heart! He slammed the table and shouted angrily: "Ignorance is extreme! How dare you say what the real 'alchemy' is? Ignorance! Ignorance!"

The old man paused, took a deep breath to suppress his anger, pointed to the piece of paper in Lu Qiming's hand, and snorted coldly: "Any alchemist with a solid foundation, according to my Dan recipe, it is impossible not to refine it!" He pointed at Lu Qiming again, and said angrily: "You! Refine quickly!

Lu Qiming watched the development of the situation in surprise, a little angry in his heart, and a little funny - this old man is such a serious character, it is really very interesting. He naturally knew about the "pill", but he really hadn't practiced it, and besides, this pill recipe was not as easy as the old man said-what it meant to be "any alchemist can do it", he knew that he wouldn't be able to do it this time. However, Lu Qiming was not ready to mention it himself, he knew-

"Just kidding, is an alchemist so easy to find?"

"The little divine doctor is originally famous for his medical skills, what is it to use alchemy to embarrass people!"

"Hey, we can't accommodate you here......"

......

You must know that although "alchemist" and "doctor" may sound like similar professions, in fact, one is in the sky and the other is underground, like clouds and mud. All the alchemists are clever doctors, but it is difficult to produce an alchemist out of 10,000 doctors!

At the same time, compared with physicians, alchemists have extremely high requirements for cultivation, and there is a strict grade division of "one to ten grades". No one has ever seen what a tenth-grade alchemist is like, but people at least know that even the lowest first-grade alchemist is respectable enough to be feared and have no worries about food and clothing for a lifetime.

Lu Qiming watched the old man's face getting darker and darker, and he was afraid that something big would happen, so he hurriedly interrupted the voice, and said: "This old gentleman, you see, I really don't know what alchemy is, then this question is my failure!"

Lu Qiming's actions became the last straw that overwhelmed the camel - the old man in brocade was furious and regained his calm, he stomped his foot lightly, and the stone slabs on the surrounding road broke outward inch by inch with him as the center, and the powerful force entered people's bodies, and everyone's chest ached;

The crowd looked at the old man in horror, no longer in the same joking mood as before.

It was so quiet that you could almost hear the heartbeat.

The old man said lightly, "Now, let's start." ”

......

In the chaotic moment when people were turning on their backs just now, few people paid attention to the fact that Lu Qiming was standing in place unscathed.

But this time it's not because of Lu Qiming himself.

Lu Qiming looked at the brocade-clothed old man in surprise - even when he was angry, his attack still deliberately avoided Lu Qiming. This made Lu Qiming a little confused, but also a little clear.

He pinched the yellowed and old piece of paper in his hand, and looked at the name of the elixir - the Five Elements Gu Yuan Dan - he needed an alchemist who could use the power of the five elements at the same time. He secretly said that these two people really knew a lot about him!

What is the purpose of these two people? Lu Qiming's expression did not move, but he was quickly combing through the information he saw in his heart, trying to judge what the two were trying to do.

"First of all, the medical book," Lu Qiming said in his heart, "Obviously, except for me, no one else knows the meaning of the various descriptions in it. ”

But it was naturally impossible for the old man in brocade and the black shadow not to be able to read it. So it stands to reason that even if I wrote the whole book silently, the old man in brocade would not be so shocked......" Lu Qiming frowned slightly, pondering, "It seems that I inadvertently answered some kind of key, but what is it?"

"That old man respects Danshu, is shocked, and expresses kindness......" Lu Qiming summed up one by one, secretly surprised: "Could it be that I inadvertently wrote something that he didn't know?"

Lu Qiming recalled the old man's subtle expression at that time, which was a look of disbelief and full of inquiry...... He raised his eyebrows, and quickly added in his heart: "Yes, they really have no intention of accepting apprentices, otherwise shouldn't it be a 'satisfied' look?"

"It's not for apprentices, it's not like an enemy, but it's not close to ......" Lu Qiming thought about their attitude, thinking about the previous scene, and vaguely felt that the answer was about to come out. The corners of his mouth hooked, so try him!

......

In the eyes of others, Lu Qiming just lowered his head and glanced at Dan Fang for a moment. He raised his head, with a sad face, and discussed with the old man in brocade: "This senior, I have indeed never practiced Dan, can you give me the book just now for reference?"

"No!" The old man in brocade immediately refused, and said resolutely, "The techniques to be used in this Danfang are clearly written in the previous book, as long as you read it carefully, you shouldn't do it." ”

Lu Qiming sighed in disappointment, so he had to sit in front of the medicine tripod with the pill and study it carefully. However, he was laughing in his heart: "Sure enough!"

This time, Lu Qiming had already been mentally prepared, and he was waiting for the old man to say this--he had already clearly distinguished that at least twenty percent of the techniques in this Dan prescription had never appeared in the previous book! It seemed that they were not only looking for people who could read medical books, but also for those who knew more.

Lu Qiming doesn't know how many books he has read since he was a child, and there is never a shortage of rare books that others have rarely seen, he only knows that he must have read the works of the same author, but it is difficult to remember when and where he read them...... But it didn't matter, this idea was just a flash in Lu Qiming's mind and he was left behind.

"If they are just greedy for the inheritance of this mysterious alchemist, they can directly ask the ...... It seems that this is not the most important thing - the important thing is to 'know' this knowledge!" Lu Qiming thought quickly, "These two people are obviously not great benevolent people who have come to give alms...... It seems that 'knowing this knowledge' represents some kind of unique identity, and those who have this identity are the ones they are going to help!"

Could it be his mother's friend? But using this way to determine his identity -- it's too unreliable! Lu Qiming smiled slightly bitterly, and there was a hidden uneasiness in his heart -- he understood that he must not know anything about one of the tricks.

After today, he could have sent someone to investigate the matter thoroughly, but he could not delay too long.

Lu Qiming took a deep breath and returned his attention to the Dan Fang in front of him.

Whether it is the refining method or the name of the herb, this pill is different from the common saying today, and Lu Qiming felt quite uncomfortable when he first saw it. Fortunately, with the previous book at the bottom, his memory of these terms was gradually stimulated, and when he read it a second time, he knew everything.

Lu Qiming turned to look at the strangely shaped medicine tripod in front of him, and the more he looked at it, the more surprised he became--this medicine tripod was hidden on all sides, inside and outside were completely integrated, and no matter what, no parts could be removed; although its surface was uneven, it was round and smooth, just like a boulder washed by water all year round, and it had a natural beauty.

The upper part of the pod has irregularly shaped panes for medicinal herbs to enter and exit. Lu Qiming looked in through the pane and found that it was actually hollow, and there was no other structure-most of the medicine tripods commonly used by Zhongzhou alchemists were very delicate and complex—which meant that he had to rely on his spiritual power to support the medicinal materials throughout the whole process of refining the medicine, so that the pill would always remain suspended!

Trouble. Lu Qiming sighed in his heart. Although mental power is his strength, and he can indeed do it, such a high requirement will inevitably greatly reduce the success rate.

Lu Qiming suddenly found that there were five points of light on the underside of the medicine tripod - one on each side, and the bottom surface of the tripod was also permeable - there were five ventilation holes!

In alchemy, it is possible to change the size and temperature of the flame only by internal force, but the consumption is too large and the time is too late, so ventilation holes are needed. However, the more ventilation holes there are, the more difficult it is to control, and each additional number of them consumes several times the physical strength and mind. Generally, the common medicine tripod only has two holes. Lu Qiming frowned, his body really didn't allow him to use the cultivation of a martial artist for a long time.

With a solemn face, he pressed his hand on the medicine pod and injected internal force into it......

What the?!

Lu Qiming stared at the medicine tripod in surprise - he had never seen a material that could conduct internal force like this - there was almost no loss, and the five elements attribute was perfectly maintained! Lu Qiming secretly breathed a sigh of relief, since this was the case, he could barely cope with it.

That's right, properties. Lu Qiming carefully compared the differences between the five ventilation holes, and combined with Dan Fang, he suddenly realized that these five holes were not only useful for ventilation, but also corresponded to the five elements!

Realizing this, Lu Qiming turned the body of the tripod in a small half circle, so that the four holes of wood, fire, metal, and water corresponded to the east, south, west, and north respectively, and the ventilation holes with the attribute of soil were located in the center and facing the ground. He thought about the various differences of this tripod, and he wondered, and he didn't know who refined this tripod, it seems that there is not only one person with the five elements in this world.

......

The old man in brocade let Lu Qiming study Na Ding carefully, and he was not in a hurry, so he sat there and watched Lu Qiming's movements.

He was obsessed with Danshu to the extreme, but he was already in his old age when he came into contact with Danshu. He knew that his thinking was limited by traditional alchemy and it was difficult to break through, so he was more humble to learn from people who knew how to innovate. Lu Qiming had distinguished the five ventilation holes according to the direction of the five elements before, which he had not thought about, but he was very interested in seeing it.

The crowd standing next to them was all anxious. There was a rare strong man sitting beside them, which really made them feel insecure; but they had just been intimidated by the old man's force, and they didn't dare to run around for a while; they wanted to turn their attention to the familiar little miracle doctor, but he stared at the medicine tripod and didn't move for a long time! Obviously, it was just a cool early spring, but people felt like they were in a hot summer, sweating on their heads, and their mouths were dry.

Suddenly! Lu Qiming moved!

Everyone's eyes are bright, like a cow drinking a bowl of iced sour plum soup, how refreshing is the whole body!

I saw Lu Qiming take out the fire and light a bright and blazing fire - people could feel the heat coming from a few meters away, and they couldn't help but retreat again and again. Immediately after that, Lu Qiming suddenly let go of his hand!

Song Ping'an, who felt the temperature of the flame deeply, almost exclaimed, she thought that Lu Qiming's clothes were going to burn up now!

But the fire didn't fall - it hung silently in the air!

How can it be?

And in the blink of an eye, Song Ping'an's heart that had just been put down was lifted again--the flames moved! It actually floated quickly towards the medicine ding!

The flames are controlled! They are controlled by Lu Qiming!

Spiritual power control - he is really an alchemist!- he is by no means an ordinary grade alchemist!

Everyone was stunned, and they all gasped in unison - they couldn't believe it for a moment, the little doctor they were familiar with with was a mysterious and powerful senior alchemist!

Song Ping'an was also completely speechless. She had the privilege of meeting a thirty-year-old second-grade alchemist, who was already considered a genius in alchemy---yet he couldn't do spiritual power control at all, let alone do it as easily as Lu Qiming! But Lu Qiming looked about the same age as her at most, was he a third-grade? Or was it a fourth-grade that she couldn't imagine?! Oh my God! What level of genius was this? Is it a demon?

Song Ping'an stared blankly at Lu Qiming's side face. The reflection of the firelight gilded his face with a faint layer of gold, his eyes were still clear, and his expression was calm and gentle as usual. Song Ping'an recalled the scene since they met, bit by bit, and all this was in huge contrast with his status as a senior alchemist. Lu Qiming was still like that, still sitting there, but she felt that he was far away and couldn't see it.

After being silent for a long time, Song Ping'an finally came back to her senses, but when she turned her head, she saw that the black and thin Fengzi on the side was smirking all over her face, and she said strangely: "Hey, what are you happy about?"

"Of course I'm happy!" Fengzi felt that he should be happy, but he couldn't understand the reaction of others, "It turns out that Brother Lu is so powerful, then I'm not afraid that someone will trouble him!

Yes, since he is an alchemist, he must also be a martial cultivator who is not weak. Song Ping'an said in his heart. She looked at Fengzi's face who was sincerely and purely happy for Lu Qiming, and suddenly understood a little bit of the reason why the relationship between the two people was so good.

Somehow, Song Ping'an's heart suddenly calmed down.

She stood in the slightly oblique sunlight and looked at Lu Qiming, who was seriously refining medicine, and suddenly smiled.
