The pill is divided into four levels: Heaven and Earth Xuanhuang, and the same is true for the Dan furnace.

It's just that the Xuanpin Dan furnace is not necessarily able to refine the Xuanpin Pill, it can only be said to increase the probability of the Dan Master refining the Xuanpin Pill. It's like letting a Dan blind who doesn't know anything use a heaven-level alchemy furnace to refine Dan, and he can still refine a pot of slag.

It was a dark night, and there was silence all around.

"It's such a quiet place, not disturbed by anyone, it's really a good place to concentrate on cultivation. ”

After Ye Zifeng dug out the Dan furnace covered by leaves, he set it up on the small stone pile that had been erected before, searched around to find some firewood, used true qi as a guide, and after igniting it, he began to add small pieces of wood to it to continuously heat the Dan furnace.

However, this time, he was not for alchemy, but for the furnace!

If you want to do a good job, you must first sharpen your tools. Once the quality of the furnace is improved, is it still worried that he can't refine a good elixir? This is also thanks to the Zixiao Ancient Sword that Ye Zifeng obtained at the Heavenly Ladder Conference, otherwise, he really doesn't know where to find good meteorite spiritual water, and even if he finds it, it may not be a spirit level.

When the Dan furnace burned red, the flames jumped.

Ye Zifeng closed his eyes suddenly, and the true qi in his body was far into the Dan furnace, thinly covering a layer of power, and blending into it. He stretched out his hand and poured the meteorite spirit water in the smallest jade box into the Dan furnace, and in an instant, a trace of gray smoke rose in a swirling manner, making a "hissing" crisp sound.

The meteoric iron spiritual water should not be poured into the Dan furnace at once, it needs to be poured evenly many times, otherwise, the Dan furnace will not be able to stand this extremely full spiritual power, and it may explode directly. Therefore, Chang Wucheng's greed for ink spiritual water, for Ye Zifeng, he could take away a few more jade boxes, which was unintentional.

Poof!

When the Fan Pin Dan Furnace received this meteorite aura, it began to shake violently, and those who didn't know really thought that this Dan Furnace was about to explode.

Ye Zifeng was not surprised, knowing that if it was just this kind of Cheng dù, the Dan furnace was actually far from exploding.

With a faint smile, he took out a second small jade box and began to pour more meteorite spiritual water.

This time, the Dan furnace was not just a shaking Cheng dù, the red flames branched out like snake letters, and a few drops of sparks splashed on Ye Zifeng's exposed arm, scalding out scorching red dots. But Ye Zifeng didn't care, staring at the edge of this Dan furnace with blazing eyes, and trying to spread this spiritual water evenly little by little.

"It should be almost enough after adding the third box......" Ye Zifeng stared at the slightest change in the Dan furnace, and already had a judgment in his heart.

In fact, it stands to reason that if you are directly promoted from the Fan Pin Dan Furnace to the Xuan Pin Dan Furnace in one go, if you only have Meteorite Spiritual Water, the effect will not be too good, but it is for a third-rate alchemist, a heaven-level peak alchemist like Ye Zifeng, as long as there is "rice", there is no "rice" that cannot be cooked.

As soon as the third box of meteorite spiritual water was added to the Dan furnace, a dazzling red light suddenly flew into the sky at the bottom of the furnace, and the angular spars were quickly formed under the condensation of the spiritual water, adsorbed on the edge of the Dan furnace, and the mysterious lines began to walk around the Dan furnace under the action of these newly generated spars, like star carvings.

This is a qualitative change caused by a quantitative change. The corners of Ye Zifeng's mouth raised a slight smile, once a mysterious pattern began to be generated, it meant that the Dan furnace in front of him began to jump from the mortal level to the Xuan level.

"With your Xuanpin Dan Furnace, any Hairong Bottle that can increase your cultivation speed after diligent cultivation can't be compared to you at all. Ye Zifeng said to himself.

In the final analysis, although the Hairong Bottle can increase the cultivation speed, the effect is very limited, for example, if a person originally went from the fourth level of Qi refining to the fifth level of Qi refining, it would take two months, then with the Hairong Bottle, the time could be shortened to one month.

However, taking the pill is different, the effect of the enhancement is extremely significant, and it is precisely because of this that the alchemists on the mainland are so precious, and the value of a thousand martial arts cultivation may not be higher than that of a single Dan cultivator. The shortcomings are naturally obvious, that is, in the case of insufficient resources in the late continent, the improvement effect is limited, but it is not as good as those martial artists who cultivate diligently, so if Ye Zifeng is not obsessed with Dan Dao, I am afraid that he is already not in the realm of martial arts.

The three boxes of meteoric iron spirit water turned into steam in an instant, dissipating in the vast space.

Ye Zifeng injected a slightly cold breath, which lowered the temperature of the Dan furnace a little, and after a while, he ruthlessly poured the fourth and largest box of meteorite spirit water into the Dan furnace.

With a "bang", the Dan furnace was impacted by this huge aura, and the mysterious lines suddenly seemed to be lit up, and the thirty-two star points in a row seemed to be connected, and faintly began to emit a faint light.

I saw that in the Dan furnace, a bright light like a bright moon rose, instantly illuminating the space beside Ye Zifeng, and the entire Dan furnace emitted a faint golden light, as if gilded.

Ye Zifeng looked at this Dan furnace with understanding: "I see, the aura of this Zixiao Ancient Sword is really powerful, and it can actually purify the dregs of the Dan furnace to this level!"

The moonlight rises and the golden light appears, in the Dan Dao Yixue, it means the meaning of purification and completeness, otherwise, the rising smoke is likely to be a cloud of black gas.

As for this Zixiao Ancient Sword, as a reward for the first place in the five-year Leizhou City Ladder Conference, it is naturally not ordinary. Ye Zifeng thought about it for a while, and couldn't help but feel a little pity, thinking that it would be good for the Heavenly Ladder Conference to issue two ancient swords, one to upgrade the Dan furnace like now, and the other to teach a commanding lesson, not to mention how comfortable it was. However, that's why Ye Zifeng would think so, in the eyes of others, not to mention the Zixiao Ancient Sword he obtained, even Shi Chen's reward as a twenty-place is also a tribute to those from small families.

However, although the aura of the meteorite has been exhausted, the purification has also been completed, and the Fan Pin Dan Furnace is still one step away from advancing to the real Xuan Pin Dan Furnace.

Ye Zifeng took out the dagger he had obtained from Wang Lin's side before, and began to reach into the Dan furnace, and began to quickly carve the edge of the mysterious pattern.

Drops of sparks splashed and fell on Ye Zifeng's arm, but he was unaware of it, still meticulously depicting this aura pattern. He understood that at this time, if his arm trembled slightly, the spirit pattern of the guide zhì was not properly depicted, and the quality of the Dan furnace would be greatly affected.

As an excellent alchemist, you must not only be familiar with alchemy, but also be proficient in the knowledge related to the Dan furnace in order to bypass.

The thirty-two star points on the mysterious pattern gradually became clear under Ye Zifeng's depiction, and the original riotous aura in the furnace began to gradually subside along with the pattern.

As Ye Zifeng completely carved the last point of the star, the entire mysterious pattern seemed to be woven into a dense network of light, containing infinite star power, suddenly emitting light towards the sky, and after a while, it was calm again.

"It's done!" Ye Zifeng smiled lightly, and his originally tightly frowning brows suddenly stretched, and his whole body was full of Tongtai.

He tried to pour his spiritual energy into this Dan furnace, only to see that in an instant, the entire Dan furnace turned into a transparent fiery red color, and under the overflowing spiritual energy in the furnace, the mysterious lines became extremely clear.

This is a feature that can only be revealed by the Xuanpin Dan Furnace! This shows that Ye Zifeng has already melted the Meteorite Iron Spiritual Water obtained by the Zixiao Ancient Sword, and has successfully upgraded the original Fanpin Dan Furnace to Xuanpin in one go!

It is conceivable that if the same pill is refined in the Xuanpin Dan furnace, its quality will be much higher than that of the pill refined in the Fanpin Dan furnace.

"Alright, since you have successfully upgraded the Dan Furnace, let's stop here for today. "There are no medicinal materials around him to refine, and even the two spirit binding pills before were made on credit from Bingqian's account, so he can't start refining them now.

Ye Zifeng smiled slightly, and re-covered some branches and leaves and other things on top of this Dan furnace, even if someone really walked by, he would not find anything unusual.

......

"Zifeng, why hasn't he come back yet, Xueyi, you said he shouldn't be targeted by the enemy, right?"

Ye Chongtian's face was not without worry, and he paced back and forth in the room.

Ye Xueyi sat on the side and looked at him with a teasing smile: "Dad, didn't you keep saying that Brother Zifeng was out to fool around?" She was used to Ye Zifeng's late return, but she wasn't too nervous.

"This ......" Ye Chongtian knew after this ladder conference, he had seen it before, his son's potential and temperament far exceeded his imagination, and he had secretly made a decision in his heart that when Ye Zifeng came back this time, he would discipline him well, restrain him, temper him, and pour the resources of a family to polish him into the future successor of the Ye family.

"Is this...... Count me wrong before, how can my Ye Chongtian's son be someone who likes to go out and fool around...... However, he hasn't come back yet, so I'll go out and look for him, right?"

Ye Xueyi smiled, and when she was about to speak, a night owl-like figure appeared in front of the two of them at the door.

"Don't look for me, I'm back. Ye Zifeng smiled faintly and walked into the hall.

"Brother Zifeng!" Ye Xueyi's eyes lit up, her beautiful eyes were shining, she suddenly stood up from her seat, and ran to Ye Zifeng with a smile.

However, she and Ye Chongtian had already noticed at this time that Ye Zifeng had come back empty.

"Zifeng, where is the Zixiao Ancient Sword that you obtained from the top of the ladder, why don't you see it with you?"
