Half an hour later, Tianjiu returned to the Dan Hall, and he and Xiao Xin hurried to the Cold Wind Hall.

In the alchemy room of the Cold Wind Hall, Tianjiu saw the second senior uncle who was fiddling with the spirit grass.

"Second Senior Uncle, what are you doing here? There are so many spirit grasses, do you want to use them to set up a stall?" Tian Jiu asked with a smile, the indescribable hypocrisy in his smile, he really couldn't figure out if Han Feng was angry with him.

Han Feng glanced at Tianjiu coldly: "Let's call me Second Senior Brother, you are all the proud protégés of the old guy, and it will be boring for me to press the cultivation to suppress you." ”

"Hehe, Second Senior Brother!" Tian Jiu shouted as he touched his head.

"How is your Xiao Yuan Dan refining? I don't dare to come these days, are you looking for the reason for the failure?"

"Hehehe!" Tianjiu smirked.

"Did you find the reason?"

"Hehe, I found it. ”

"Huh, found it?" the cold wind stepped forward, "Are you sure to refine?"

"I'm not sure about the earth fire, but I can try the Dan fire, but there is no guarantee that it will be successful. ”

"Oh, Danhuo refining, can your Danhuo last that long?"

Seeing Tian Jiu nodding exactly, with a wave of Han Feng's hand, a medicinal herb flew out, and ordered: "Here is a material, you use Danhuo to refine it, see what the result is, I don't blame you for refining it." ”

"Second Senior Uncle, you don't punish him? This is too boring, no pressure, he will definitely not be able to refine!" Xiao Xin shouted heartlessly on the side.

"Go, go, go, I don't know your ghost's thoughts, I only know that I slandered this kid's spar, today I changed my mind, if he succeeds in refining, I will reward each of you with a hundred spar!" said Han Feng with a dark face.

"Yay, big brother, come on!" Xiao Xin jumped up instantly.

Tianjiu shook his head, and wiped out the Youjin Ding with a smile and a smile......

More than four hours later, in the smell of burnt paste and aroma, a furnace of elixir was baked.

The cold wind hurriedly lifted the lid of the furnace. Inside the Youjin Ding, seven tender green, slightly cloudy pills with a slightly turbid body were constantly rolling, and at the bottom of the furnace, three piles of black slag were also embedded in the pills, emitting an unpleasant smell of burnt gas.

"Seventy!?" Han Feng was dumbfounded, not believing the facts in front of him at all. However, he still quickly collected all the Xiao Yuan Dan in the Ding, and took advantage of Tianjiu and Xiao Xin's unpreparedness to quietly stuff them into his sleeves

"Big brother, you're so powerful! Xiao Xin loves you to death!" Xiao Xin ran over from a distance, hugged Tianjiu's arm and shouted.

"Cut! I don't know who hid so far, for fear that I would blow him up!Go away, go away, and go cool!" Tianjiu waved Xiao Xin's little hand angrily.

"No, I was scared of your bombing last time, so stay away, don't be angry, next time I'll definitely sit next to you, how about it?"

“hahahaha！”

As Xiao Xin was speaking, Han Feng raised his head and smiled, pointed at Tianjiu and said, "Genius, genius! I didn't expect our Dantang to actually pick up a genius!"

After speaking, he took out a pill again, stared at it for a long time, nodded and said: "Yes, the Xiao Yuan Dan you used to refine with Dan Fire is even better than the quality I refined with Earth Fire, almost reaching the middle grade, and the Cheng Dan rate has also greatly increased, I only had a forty percent Cheng Dan rate last time, but you have reached seventy percent, which shows that the quality of the earth fire is not high and the temperature changes frequently, which seriously affects the effect of alchemy." ”

"Second Senior Brother is saying that this earth fire is unstable, which is the reason for my failure last time?"

"You have given me a new idea, I may have to use the Dan Fire to try to refine the Tsukidan!" said Han Feng's eyes shining, and he said with a radiant look.

"How long will it take?" Tianjiu felt a pang in his heart. If you can refine it yourself, it won't save you a lot of trouble.

"Earth fire takes four days, while Dan fire can take about three and a half days. ”

"Three and a half days?!I thought it would be five or six hours at most!" Tianjiu shuddered, for such a long time, he had already been squeezed dry!

"Hmph, you think this is the old guy's bone-setting pill, just do it and it will come out! Otherwise, anyone can build a foundation!"

"Hey, too. But for such a long time, can the dantian stand it?"

"Of course, with my current cultivation, I will definitely not be able to last so long, but I can use it with a combination of earth fire and Dan fire, as long as I cooperate properly, I may not be able to succeed. I'm so smart!" the cold wind shouted smugly.

"Hey, hey, the second uncle also has times when he brags!" Xiao Xin shook his head, very disapproving.

"Is it?,

"Second Senior Brother, can you give me a copy of the Danfang of Tsukidan?"

"Huh, you also want to refine the Dan Fang, it's no problem, but I don't have much of this medicinal material for you, this Zhuji Dan's medicinal material is too precious, and there are many varieties, it took me almost a whole year to get a copy, and I don't know how much anger I have suffered from that Yan Pozi!"

"Huh?" Tianjiu almost fainted, these two senior brothers actually went to steal other people's elixirs for the sake of alchemy, and instead said that they were angry with others.

"Second Senior Brother, how many kinds of medicinal materials are there in Zhuji Dan?"

"One hundred and eight, of which twenty-eight are the main medicines. This is Danfang, you can take it and see it yourself. The cold wind was refreshing, and he took out a crumpled piece of paper and handed it to Tianjiu.

Tianjiu took it as if he had received a treasure, looked at it carefully, and muttered, "It's okay!"

"Hmm, what did you say, okay, do you think it's not much, have you seen all these herbs?"

"Oh, no, no, no! I mean, this Dan Fang is good, Dan Fang is good!"

Tianjiu hurriedly denied it, in fact, he had carefully compared it just now, although the Dan recipe of Zhuji Dan was extremely complicated, but the twenty-eight flavor main materials, he could immediately get more than ten kinds of them, and the others were estimated to be in the Qiankun Ring, but he didn't know it.

"Tianjiu, I decided to start refining Zhuji Dan right away, you can watch from the sidelines, the time is a bit long, you have to endure it. This first day is the most critical, all the herbs are added on the first day, and the last two days are under fire control, if you can't stay up, you can go out for a walk......"

"Thank you, Second Senior Brother, I just want to stay with you, but the master is there......"

"What is there to go to the old guy, I have his Zhuji Dan refining method here, if you want it, I will give it to you immediately, I know him too well, a Dan prescription can remain unchanged for thirty years. ”

"Hey, hey, hey, I'll fight, I'll fight!" Tianjiu sneered.

"Hmph, whatever you want!" Han Feng was a little displeased, "Xiao Xin, you go back!"

"Second Uncle, don't you want to reward me with the spars, and the first few commissions?" Xiao Xin asked in a low voice.

"Uh?" Han Feng shyly pointed to the elixir on the ground: "The hedron has turned into grass, if you want, take a few back, don't, just get out!"

"You...... You...... Liar!" Xiao Xin lowered his little face.

"Xiao Xin, don't be discouraged, you go back first, my brother will definitely take you to a meteor ride in a few days!" said the Nine Thieves laughed.

"Really? didn't lie to me?"

"What are you lying about? But if you want to go back and give the master a sloppy look, just say that I have been practicing the exercises for the past few days, and I don't have time to go to him for a while, so don't say that I missed my mouth. ”

"As far as your virtue is concerned, who believes it! I think it is better to say directly that you are going to earn spars, which is more in line with your identity as 'Jing Ye', and the master may believe some of it. Xiao Xin sneered.

"Go and go, whatever you want, as long as the master doesn't find here, otherwise, the master will have to pinch your second uncle!"

When Han Feng heard Tian Jiu's words, he didn't react in the slightest, and checked his treasure herbs wholeheartedly. All the herbs are placed in the stone chamber according to their priority.

With all this done, he took a deep breath, sat cross-legged in the center of the stone chamber, closed his eyes and meditated.

Xiao Xin had been accompanying him at first, sitting beside Tianjiu, and after a while, seeing that no one was paying attention to him, he felt bored, so he got up and left the stone room with a small mouth.

Half an hour later, the eyes of the cold wind suddenly opened, with a wave of his hand, a small blue Dan furnace flew out, the Dan furnace dripped, buzzed, swelled to the size of a basin, the emerald green furnace body, engraved with three big characters - Bi Ling Ding

"Old ten, this Biling Ding, ranked among the four Dings, below Ning Yuan Dan, can be refined, can gather the aura of heaven and earth, can absorb the essence of heaven and earth, it is handed down by a senior master of Dantang in the past, and even the old guy is red when he sees it. Although it can't compare to the old guy's Blood Yang Ding, we want to refine the Zhuji Dan, and it has to be!"

After the cold wind finished speaking, his face showed a smug look, and then he pointed out his right hand, and with a hula, a huge red and white spark shot out. Sparks flickered on the cold wind's fingers, revealing a terrifying heat wave.

Bi Lingding slipped around again, and landed accurately on the sound of sparks. After a while, on the emerald green Ding's body, the aura was flipped and verdant.

Han Feng nodded in satisfaction, and with a wave of his left hand, seven or eight flavors of medicinal herbs flowed in. There was a beeping horn in Biling Ding......

Tian Jiu stared intently, meticulously understanding the method of refining, and his face showed doubts and incomprehension from time to time......

The cold wind's dark and old face, under the illumination of the Danhuo, revealed a state of full confidence, as if he was twenty years younger all of a sudden, and his skillful cooperation showed a high-spirited master demeanor. I saw the Dan furnace flying, the lid of the furnace opened and closed, and a trace of cyan heaven and earth spiritual energy continued to gather in the Dan furnace, and the original emerald green Dan furnace gradually turned into a dark green color......

Tian Jiu didn't dare to interrupt in the slightest, and even breathed a lot slighter, for fear of destroying the cold wind's completely self-contained alchemy state.

Three hours later, the cold wind gently wiped the beads of sweat on his forehead, and the old face that had been calm suddenly laughed: "Old ten, if you have any questions, don't suffocate yourself!"

"Second Senior Brother, didn't you say that you wanted to mix and refine with earth fire?

"Alas, I can still hold it now, I wish I could use all the Dan Fire to refine, but it has been more than three days, I really can't stand it! I'll do my best, this is the most critical stage of turning grass into liquid without any mistakes, it's better to use Dan Fire, and in the next stage I began to consider using Earth Fire to relay. The cold wind explained while outputting Danhuo, and after more than three hours of refining, his face also showed a look of exhaustion.

Tian Jiu nodded thoughtfully, and after asking seven or eight questions one after another, he finally had a general understanding of the key to refining Zhuji Dan.

After a few hours, he felt that he really had nothing to do, so he quietly took out a top-grade Xiaoyuan Dan and threw it into his mouth, and then, while refining, he watched the cold wind refine the Zhuji Dan with a serious face......
