I don't know what the reason is, Yan knocked on the door several times in a row and no one answered, after all, he didn't dare to continue knocking on the door because it would be too rude.

In the evening, he ate a little, and he didn't understand the questions he had summarized this afternoon, so he could only read other books now.

He could study the book on medicinal herbs and the pill for practicing his hands first.

Of course, when he heard Miss Yue'er preach Dan Tao before, the other party also gave him a few elementary pills, "When I am familiar with these herbs in the past three days, I will try them again!"

……

It took three days to memorize a book, it was really too simple for a Gu master, to be precise, it took two days to memorize it backwards.

Of course, he memorized it on the first day, and the second day was more about consolidation and thinking.

"Most of this golden flower and grass are golden dao traces, and the most fundamental thing in itself is the wood path attribute!"

"If the wood is weak, it is born with gold!"

After reading this book, some of the problems before the severity were solved, but he was also wondering why the two seniors had disappeared for three days.

Yan Yan walked out of the door and began to walk towards the medicine garden, "Since he didn't look for me today, I'll just try refining a pill first!"

There was a strong aroma in the medicine garden, and when you inhaled it gently, it made people feel refreshed and happy, and they felt that all the fatigue in their body had disappeared.

"Immortal-level medicinal materials are really different. Grim unconsciously sighed: "This fireworks just smelled it and found that the body was light and fluttering!"

Of course, it was useless for the immortal material to be taken severely, and he had no way to take it, so at this moment he went straight to the point, and according to the content recorded on the Danfang given by Wu Mu's predecessors, he began to find those herbs.

The pill given by Wu Mu's predecessors, all the herbs on it can be taken directly, Yan Yan took out the hoe in the medicine basket on his back, squatted down and gently hoeed a green grass, he didn't cut off the roots in order to let it grow again.

Grim left to search for right, although some materials are a little biased, but the hard work pays off, and he still makes it up.

At this moment, Yan Yan carefully held the most precious herb in the Danfang in his hand, "Sure enough, the ghost eye flower will only grow in the shade, and it will be cultivated with golden toad saliva!"

After carefully exiting the medicine garden, Yan Yan walked straight into the alchemy room, because he was holding the ghost dazzle in his hand, he could only use his body to open the door.

The light entered the room, and the first sight of the grim saw a big Dan furnace, the Dan furnace was engraved with a big seal written "immortal" word, nothing else, the only feature is that it is large, almost occupying one-third of the space of the room.

Yan Yan found a pot to put the ghost eye in it, and then quickly poured some ice water into it from the side, because the cold air can help the ghost eye to preserve.

"Prepare three materials to practice, it should be enough!"

Then he lifted the top of the furnace and opened the Dan furnace, and compared with the stove, there were not many herbs in the medicine basket on his back, and all of them were poured into this big Dan furnace, which really gave people a feeling of overuse.

Yan Yan slowly lowered the top of the furnace, then took a few scoops of water and poured it into the furnace, and then directly poured the true yuan into this Dan furnace.

The output of the true element is not large, but the burning furnace is quite vigorous.

When the water was boiling, he took out the first herb from the medicine basket, threw it in, and continued to close the top of the stove.

After about a moment, he immediately opened the top of the stove and quickly put in the second herb wolfberry.

The Dan furnace was full of water, and the two medicinal herbs were boiling in the boiling water, quietly dyeing the boiling water with a faint layer of yellow.

The heat and time of alchemy require the accumulation of experience. And experience is such a thing, and you have to slowly become proficient.

Therefore, all he could do was to stare at the sundial outside the door, and every moment he quickly lifted the top of the furnace to throw medicinal herbs, and as for the heat, he continued to input the true yuan.

"How do you feel that my current behavior is not much different from that of mortals boiling Chinese medicine. ”

Grim can't condense the pill, so he immediately thought that if after three hours, what was boiled out was just an ordinary bowl of Chinese medicine soup, I don't know what the result would be?

Wu Mu's predecessor gave him a 'Quenching Pill' pill, which can make him look at his own talent in one go!

As the heat in the Dan furnace rises, the temperature in the Dan room also rises rapidly.

Grim felt a little irritable, he first went to find the place where the ice cube was, and suddenly found that there was a pair of ice beads there, at this moment he divided some true elements into the ice beads, and there was a burst of coolness in an instant, which made Grim feel cool.

Not only that, but the ice beads made Grim's mind clear. Unconsciously, I entered a state of extreme concentration.

Severely pinching the third flavor herb, the calm mind also made a little waves, this third flavor herb is called 'Chaolu Xuancao'!

In terms of shape, this Chaolu grass is not much different from ordinary grass, and it is a green strip plant. However, if you look closely, you can see that there is a mist on the grass that does not disperse, such as the morning dew on the blades of grass that disappears from time to time.

Soon, another quarter of an hour passed, and he picked up the top of the stove with an iron rod that had already existed on the side, and the morning dew grass pinched between his fingers was thrown into the furnace, and then the top of the stove was quickly closed.

He had some expectations in his heart, this step was also a crucial step, because this special herb could make some special changes in the previous two herbs in the furnace.

Like the previous two herbs, the morning dew herb tumbled and floated in boiling water.

His grim eyes were still staring at Chaolu Xuancao, and there was a hint of coolness from the ice beads next to him, which made his spiritual power unprecedentedly concentrated!

Gradually, the three medicinal materials in the furnace magnified in his grim eyes! At this moment, there were only medicinal materials in his world, and there was nothing else.

I don't know if it's because he was so focused to the extreme, Yan Yan was gradually able to detect every subtle change of the three medicinal materials in the boiling water.

Every time it rolls, a light yellow medicinal property is boiled out of the herbs and integrated into the medicinal soup. When the ginseng slice exudes medicinal properties, the body size swells a little after melting.

It's such an amazing feeling!

"Firepower, it seems that there is not enough firepower?" suddenly appeared in Grim's heart.

He felt that the medicinal herbs in the Dan furnace needed more firepower, especially the Chaolu Xuancao, which needed a higher temperature to stimulate it!

Therefore, he did not hesitate to increase the True Yuan input, and in an instant, the temperature of the Dan furnace increased.

Whoa~

The water in the Dan furnace boiled even more, and the lid vibrated under the impetus of water vapor.

The grim eyes widened even more - after increasing the temperature, the Chaolu Xuancao actually changed!

The morning dew grass that was originally floating on the water melted all at once!

As the herb dissolved, the medicinal soup was stained with a layer of turquoise liquid. The turquoise liquid wrapped up the ginseng slices and goji berries in the furnace as if it were spiritual.

After the two medicinal herbs were rolled, they also began to slowly melt and mix into the turquoise medicinal liquid.

The grim heart picked up a beat slightly.

Magical change!

At the same time, he vaguely guessed in his heart that maybe the Quenching Pill might not need to add water at first, but if it was heated in a special way, ginseng and wolfberries would be heated. The moment you add the morning dew herb, the liquid can be melted.

He didn't know if the furnace had failed.

Fortunately, he had already prepared for failure, and he had prepared a total of three medicinal materials, and the main purpose of refining this time was to familiarize himself with the process and record the problems in the refining process.

A quarter of an hour had come again, and this time he calmly took out the fourth herb and quickly threw it into the Dan furnace.

It didn't take long for this fourth herb to also be caught in the turquoise medicinal liquid, melting in the medicinal liquid little by little.

The grim eyes were still staring at the medicinal herbs in the pot, and the more and more enlightenment was realized in his heart. "Under this level of firepower, the time it takes for the fourth flavor herb to completely fuse with the liquid medicine is about a moment. ”

"There are also differences in the size, shape, and year of medicinal materials, the different temperatures of the fire, and the different quality of the alchemy furnaces, which also need to be understood. ”

The fact that he was able to make such progress at the moment was first of all due to his own keen insight and relevant knowledge, and secondly, to the calming effect of the ice beads in the room.

This ice bead calms the grim mind like water, and the mind becomes clearer and clearer while concentrating.

Of course, it may also be severe, and he seems to have a natural sensitivity and intuition for alchemy. This is an innate talent, and if he wants to be an alchemist in the future, this talent can also allow him to do twice the result with half the effort.

Soon, after Yan Yan's understanding of Wu Mu's predecessor's Danfang became more and more thorough, all the actions gradually began to become smooth.

He began to decide the time to put in the herbs next time based on the degree of fusion of the Dan liquid in the furnace. Sometimes, he would put in the next herb in half a quarter or so. Sometimes, it is more than a moment long.

Before I knew it, half an hour had passed.

After fusing the sixteenth herb, the fusion ability of the Asahi Gencao in the furnace reached its limit. At this time, according to the record on the Danfang, another special medicinal material 'Sansheng Fruit Pit' was severely invested.

Indeed, like the morning dew herb, the Sansheng Fruit Pit has regained the responsibility of a new 'fusion herb'.

The liquid medicine in the hot pot pot did not dry up after burning for more than half an hour, but increased slightly.

Put in the herbs, pay attention to the degree of fusion of the herbs, wait, and then continue to put in the herbs. The process is boring and extremely boring, but there is no room for negligence.

This is an alchemist! A profession that needs to be harsh to perfection, it is a one-in-a-million existence, and it is a profession that can only be undertaken by people who can really live in loneliness.

More than two hours later, Grim's eyes were still bright, but his body was a little tired.

"The forty-first taste of medicinal herbs is finally coming to an end. Grim muttered.

I really didn't expect him to be able to persist to this point in the first alchemy. But he's almost at the limit now. After this flavor medicine, there are only fresh overlord branches, Jiuyang Chiyan bamboo slices, deep sea cold crystals, and snow demon core four flavor medicinal materials, and I don't know if he can survive until the end!

Lift the top of the furnace and quickly put the forty-first herbs into it.

Before the severeness could close the lid on the ding, a mutation protrusion appeared in the Dan furnace.

When the light gray liquid that was originally fused with forty flavors of medicinal herbs came into contact with forty-one flavored medicinal materials, it suddenly burst out with a foul smell and burnt smell!

There was already half a pot of medicinal liquid in the Dan furnace that was quickly steamed, and in the blink of an eye, it was less than one-fifth!

"Tsk, did you fail?" said Grim in distress, "Could it be because of the water added in the first place!"

Grim wonders if he failed in the first place.

But until the forty-first taste of medicinal materials has no problems, he will inevitably have a trace of expectation and hope in his heart, this is the unique gambler psychology of human beings, right?

It's a pity that now it's finally going to be a complete failure?

"No, it's not completely finished. "Grim to see, although the gray liquid is being steamed, it is still tenaciously fusing the forty-first flavor herbs.

He knew he had to do something now, and if he didn't, he was really going to be finished.

In fact, the forty-first herb is indeed the most difficult step of the 'Quenching Pill'.

From this step onwards, it is actually the stage of the end of the 'Quenching Pill'. The four flavors of herbs after this herb are no longer increasing medicinal properties.

Fresh Overlord Branch, Jiuyang Red Flame Bamboo Slice, Deep Sea Cold Crystal, Snow Demon Core, the first two to the yang to the rigid, the latter two to the yin to the soft. The four flavors of medicinal materials are used to purify the 'quenching pill'.

The most important step in purification. If it is not purified, the quenching liquid in that furnace is at best a pot of perfect tonic soup. After drinking it, it will make people feel great, but the quenching effect is greatly reduced. After adding the purification step, through the unique condensing pill technique, this perfect tonic soup can be transformed into a real quenching pill, as if it has been transformed into an elixir from an ordinary medicine.

And the first forty-one herbs are the introduction to purification.

This step is indeed the easiest part to fail, and many Dan masters have failed ten times when they first practice this pill formula.

But what can be done to recover from failure?

If Wu Mu's predecessor was present, with his high realm of refining Dao, he would be able to turn the tide without any effort and bring back the 'Quenching Pill' of this furnace.

It's a pity that the first is inexperienced, the second is not technical, and the third is not yet in the realm.

"Evapotranspiration is too fast, and we have to slow down the process. Add water!" grimly subconsciously became a dead horse doctor, adding water to the stove one scoop after another, although I don't know if it can work, but at least the speed of evapotranspiration has slowed down a lot.

Grim thinking ran wildly, "What should I do if there are still four herbs left?"

Yan Yan decided: "Put all the remaining medicinal materials in it in one go, and try it." Anyway, it's close to failure, so let's just absorb experience. ”

Lift the top of the furnace.

Fresh Overlord Branch, Jiuyang Red Flame Bamboo Slice, Deep Sea Cold Crystal, Snow Demon Core, the four medicinal materials were thrown into the Dan furnace in one breath.

Cover the lid!

Subsequently, Grim saw the real 'two heavens of ice and fire'.

Xianbawang branch and Jiuyang Chiyan bamboo slices fused with part of the medicinal liquid, and these two herbs turned red when heated, as if they were about to burn. This part of the liquid becomes more boiling and steaming faster. Steaming gases gush out of the vents in the lid like a fountain.

The two things of the Deep Sea Cold Crystal and the Snow Demon Core were in heat, and the shells cracked, gushing out of the ice-blue liquid. The ice blue liquid seemed to be extremely cold, and after fusing the other half of the liquid, the boiling liquid began to cool down calmly.

The calm part is getting cooler and colder, and the boiling half is steaming faster. There were signs of separation between the two parts of the liquid.

"They can't be separated. Grim's heart moved, and the firepower of the accelerated true element output suddenly increased, trying to make the cooled part boil again.

As the temperature increases, the degree of evapotranspiration of the liquid becomes faster. Less than thirty breaths, the original furnace of medicinal liquid is about to bottom.

At most, ten more breaths will be steamed.

"It's a complete failure. Grim laughed, after all, he had been mentally prepared, so he didn't care about failure.

He wanted to remove the true yuan, after all, if he continued to burn like this, he was afraid that the result would be worse.

But in the next moment, although the liquid steamed faster, it was no longer polarized and fused again.

The devil makes the gods worse, and the grim choice continues to maintain the status quo!

Throwing a single shot, adding fire to the fire, he fused all the medicinal liquid in one go, and purified all the medicinal properties of the forty-five kinds of medicinal materials and forced them out! In this way, maybe before the liquid medicine was steamed clean, he could still get some scum?

A strange noise began to come from the Dan furnace.

Ice and fire intertwined in the Dan furnace, turning into beautiful shapes, and only the two remaining streams of liquid medicine tumbled.

Seeing that the liquid medicine became viscous, he quickly withdrew the true yuan, slowly lifted the lid of the tripod, and a stream of steam immediately gushed out under the residual temperature of the Dan furnace, and after the liquid medicine was steamed, a thick layer of impurities was pasted on the lid of the tripod.

Tick, tick...... It's the sound of herbs rolling slowly.。。

Because the steam had not dissipated, he couldn't see the situation in the Dan furnace clearly, so he could only wait silently.

Soon the steam dissipated, but then a burst of black smoke erupted, enveloping the entire Dan room, and the smell of rushing to the nose came to the nostrils.

The smell was so punchy, it was like a fusion of all the bad smells of the world. Just accidentally sniffing it makes me feel the urge to vomit.

Sternly pinched his nose and "vomited ......"

"It stinks. Even though I pinched my nose and held my breath, the strange stench still penetrated into my grim nose and lingered.

If he hurriedly opened the windows and doors to prevent him from breathing, he was worried that he would be 'stinky to death', and he would be covered in smell.

As soon as the windows and doors opened, a black mist drifted out of the windows, and the stench in the kitchen gradually dissipated.

"I can't describe the smell in words. And it's a lot of aftertaste. Yan shook his head slightly and sighed, it is estimated that he will not be able to forget this smell in the past two or three days, and he doesn't know if he can eat next?

"The lethality of this thing after refining it is so terrifying that it can be used as a biological weapon. If this smell can be collected, I will release a room into his room to ensure that the aftertaste is endless. "Grim self-deprecation. At this moment, I felt a dizziness in my head. Exhaustion came to him like a sea of mountains, which was the fatigue accumulated in nearly three hours!

Grim hurriedly held on to the table and sat down slowly, rested for a while, and pinched his nose and looked at the bottom of the pot, wanting to see what kind of thing could dissipate this foul smell after the product of his failure in the end?

There is only a thin layer of liquid medicine left in the Dan furnace, which is black and transparent in color, with a pungent smell.

"It's black and mushy, and it looks a bit like transparent sesame paste. It just stinks. Grim habitually complained, "Huh......? How come?"

However, he found that the remaining products in the Dan furnace did not smell at all and were very sober, "But why is it not an elixir?"

Grim asked and answered: "I know, I don't have a specific method for Ning Dan, so it can't be formed!"

"Could it be that the stench just now is because I didn't have Ning Dan in my last step?"
