Lin Yan carefully put these medicinal materials in batches according to the Dan prescription. His whole mind was in the furnace.

The flame under the Dan furnace, Lin Yan was also cautiously controlled, for fear that the fire would be too big and destroy the pill, for fear that the fire would be too small and the pill would not be able to be practiced.

Half a day later.

A viscous liquid had already gathered in the Dan Furnace, and at the same time, an almost inaudible distant thought had escaped from the Dan Furnace.

The moment Lin Yan was meditating smelled this shallow fragrance, his eyes opened suddenly, and two rays of light flashed, as if he could see inside.

"Is this the liquid medicine?" Lin Yan's divine sense locked onto the suspended liquid in the Dan furnace and whispered to himself.

"This liquid seems to be very pure, and it seems that the impurities in it have been refined. Lin Yan's eyes narrowed slightly, "Then the most critical stage of condensation begins." ”

Lin Yan stood up suddenly, his hands flipped quickly, and he made a series of extremely simple handprints.

This handprint was just those ordinary Ning Dan recipes, which he had recorded from the book he had bought from Mingyang City.

Sure enough, a series of handprints were made.

The medicinal liquid in the Dan furnace slowly divided into several piles, quickly condensed together, and turned into light white pills one after another.

Seeing this, a smile appeared on the corner of Lin Yan's mouth. But the next moment, the smile on his face suddenly froze.

There was a dull sound in the furnace, as if something had exploded.

Lin Yan's face suddenly became extremely ugly, and the Pei Yuan Dan that had just been refined was all destroyed.

With a wave of his right hand, Lin Yan opened the lid, took out the residue in it, and placed it in front of him.

"What's the matter, it's obvious that the refining has been successful, but why did it all ruin in the end?" Lin Yan frowned, and there was confusion between his eyebrows.

Lin Yan followed the process every step of the way, and it stands to reason that this situation should not come out.

"What went wrong?" Lin Yan kept recalling the previous steps in his mind, but he still didn't understand what went wrong.

Lin Yan retracted his gaze and secretly said that this is just the beginning, try it again.

Lin Yan said he would do it.

............

Bang.

"It still failed. The doubts on Lin Yan's face were deeper, and he himself paid more attention than the previous time, but when it came to Ning Dan at the end, it still exploded.

"No, do it again. ”

Bang.

The third time still failed.

Lin Yan still didn't give up.

For the next seven days, Lin Yan had been refining Pei Yuan Dan, but all of them ended in failure without exception.

Lin Yan looked at the dregs of medicine in front of him with a bitter face, and secretly said in his heart that this was the twenty-eighth failure, and every time it was at the last moment.

During this period, he thought about what he was wrong countless times, but with his meager foundation, he hardly came up with any results.

Lin Yan sat on the ground a little decadently, and his heart said that he really didn't have the talent for alchemy, but even if I didn't, I wouldn't be able to refine even such an ordinary pill.

"What went wrong, the steps, the materials, or the Dan furnace, the heat, or the Ning Dan recipe?" Lin Yan kept recalling in his mind.

In the next two days, Lin Yan was not opening the furnace for alchemy, and he knew in his heart that if he didn't figure out what the problem was, the final result would be the same.

............

Knock knock.

Lin Yan, who was still reflecting on why he had failed in alchemy, was interrupted by a slightly dull knock on the door.

Lin Yan frowned slightly, a little dissatisfied, and immediately asked, "What's bothering me?"

"Senior, the time you want has come. A childish voice sounded outside the door.

When Lin Yan heard this, a sudden look appeared on his face, he didn't expect that he had been here for ten days.

"I didn't feel the slightest feeling. The corners of Lin Yan's mouth showed a touch of bitterness, the failure of this period of time had already made him feel helpless about alchemy.

"Oh, I see. ”

"Do you want to extend the time?" the immature voice sounded outside the door again.

Lin Yan held his forehead with one hand, struggling in his heart, not knowing whether he should continue, if he succeeded, it would be fine, if he failed......

"Have you thought about it seniorly?" Lin Yan may have been thinking about it for a long time, and there was already a trace of impatience in the voice outside the door.

"Forget it, you can't go on like this without results. Lin Yan slowly stood up, walked to the door, opened the door, and looked at the little boy in front of him.

Xiao Tong saw Lin Yan, who suddenly opened the door with a slightly embarrassed face, and showed a funny look on his face.

But then the boy lowered his head suddenly, and he found that the person in front of him was staring at him, and he couldn't help but feel afraid.

"It's the kid of that day!"

Lin Yan's eyes narrowed slightly, by the way, maybe this little boy can find out the problem.

"This little boy may still be young, but staying in this alchemy room, under the influence of his ears and eyes, I am afraid that he will also have some alchemy skills. ”

It may be that this kid hasn't officially come into contact with alchemy, but I'm afraid it's much better than Lin Yan, a halfway monk.

"Boy, let me ask you a question?"

"Senior, may I ask?" the little boy subconsciously shuddered, thinking that his behavior just now had caused Lin Yan's dissatisfaction.

"How long have you been in this alchemy room?"

"Ahh

However, under Lin Yan's gaze, Xiao Tong suddenly said loudly: "I came here when I was eight years old, and it has been almost four years. ”

Lin Yan raised his eyebrows, and a hint of joy flashed on his face.

"What do you know about the art of alchemy?" asked Lin Yan with a hint of hope in his eyes.

"The kid just touched a few. ”

Lin Yan suddenly smiled, lifted the little boy in, and closed the door with a wave of his right hand.

Lin Yan's sudden movement obviously scared the little boy to tremble.

"Senior, you... What are you going to do?"

"Don't be nervous, boy, do me a little favor, I won't treat you badly. Lin Yan put the little boy down and said softly.

The little boy looked at Lin Yan and nodded as if he didn't understand.

"You've been in there for so long, you might be able to see what went wrong. Lin Yan said to the little boy beside him while turning on the furnace.

Then Lin Yan didn't pay attention to it and focused on refining the elixir.

And the little boy was watching carefully from the sidelines, not laughing.

Lin Yan had been paying attention to the Dan Furnace, but he didn't pay much attention to it.

Bang.

Lin Yan looked at the Dan furnace helplessly, and failed again.

Then Lin Yan set his eyes on the little boy beside him, and asked in a low voice, "Can you see where the problem is?"

Xiao Tong looked pensive, but because he was too young, the expression on his face was a little strange.

"Senior, have you never been exposed to alchemy and those spirit grasses?" asked the little boy in a tender voice.

Lin Yan nodded.

And so it was. Xiao Tong said with a look on his face.

Lin Yan raised his eyebrows slightly and asked, "What did I do wrong?"

"Senior, first of all, the first point is that you got the materials in the wrong order. ”

"Huh?"

"The properties of each herb are different, some are too strong, some are too cold, and they are mutually reinforcing. ”

"My grandfather once told us that the most important point of alchemy is that the order in which the materials are put must not be wrong, and if you make a mistake, this furnace of elixir will be completely ruined, even if you are lucky enough to refine the elixir, it will be inedible. ”

"Take the Pei Yuan Dan refined by the predecessors as an example, among the ginseng flowers, the medicinal properties are domineering, if the herbs of Tongqing Ling are slightly feminine, if they are put in the wrong order, then it is not Pei Yuan Dan that is refined, but poison. ”

When Lin Yan heard this, he was frightened, fortunately, this Pei Yuan Dan was not practiced, otherwise it would be himself who suffered.

"This is the first point, and the second point is that the timing of the predecessors to use the Ning Dan Jue was wrong, which is also the key reason why the pill cannot be practiced. ”

"Oh, when was this Ning Dan Recipe not the last time it was used?" Lin Yan asked curiously.

"Rather, it is used at the end of the liquid to solidify itself. If it is used in advance, it will only make the internal of the pill very unstable, and finally destroy it like its predecessors. The boy told all the mistakes he saw in one breath.

Lin Yan's face was sudden, and he secretly said in his heart that this alchemy was really profound. But then he thought that he didn't have a solid foundation and thought about refining the pill, which was really embarrassing.

"Alas......" Lin Yan sighed.

Then he took out a medium-grade spirit stone and handed it to Xiao Tong, saying, "This is a reward for you." ”

Xiao Tong didn't expect that the other party would only give him a spirit stone, and a trace of unhappiness flashed on his face, and he took it a little reluctantly.

I've also seen the lower grade spirit stone, and this doesn't seem to be the lower grade spirit stone. The little boy took the spirit stone and whispered with his eyes open.

Don't......

This turned out to be a medium-grade spirit stone!

"Then I don't just have a hundred low-grade spirit stones. The child's eyes narrowed, and his face bloomed with a smile.

Then he carefully put it away, and saluted respectfully to Lin Yan: "Thank you seniors." ”

"You deserve it. Lin Yan said with his hands behind his back.

"Senior, these words are not worth so many spirit stones, and the kid doesn't want to take advantage of his predecessors. ”

"Oh, then what do you want to give me?" Lin Yan said with a smile on the corner of his mouth as he looked at the little boy.

"The predecessor is so keen on alchemy, the kid can help a little. ”

Lin Yan put away his smile.

"There is a place in this alchemy pavilion where jade slips of alchemy from all aspects are collected. There are some jade boys in it that can be used to give to seniors. ”

"Oh, really?" Lin Yan suddenly asked with joy.

Xiao Tong nodded earnestly.

"Won't this get you in trouble?"

"Those are the foundation of alchemy, and nothing will happen. ”

Lin Yan nodded slightly.

Then Xiao Tong was about to turn around and leave, but after a few steps, he suddenly slapped his forehead and turned to look at Lin Yan suddenly.

"What else do you have to do?"

Xiao Tong touched his head a little embarrassed and said, "I forgot to say that if the seniors want to continue to stay, they will have to pay the spirit stones?"
