Gently untie a red rope tied to the mirage crystal nucleus, and after thinking about it, Ling Feng still put the red rope away.

How to say that this is also a "gift" from his own students, the mirage crystal nucleus must not be kept, this red rope can be left as a souvenir.

The other three top alchemists glanced at each other, not caring about this small detail, just wanting to see what Ling Feng was going to do with this mirage crystal nucleus that had been sealed for more than ten years.

It can be said that the Mirage Crystal Nucleus is the top priority in refining the Demon Pill, and if the Mirage Crystal Nucleus is not handled properly, there is basically no possibility of successful refining.

In the next moment, Ling Feng had already activated the Earth Fire True Qi and began to gently melt the amber layer condensed on the surface of the mirage crystal core.

The amber layer was specially ordered by General Deng Lao to be smelted by craftsmen in order to prevent the energy in the crystal nucleus from leaking out, but now the amber layer must be smelted away in turn to extract the energy inside.

"Fire in the Center of the Earth!"

Su Dongling nodded secretly, although Ling Feng's Earth Fire True Qi was much worse than the Purple Flame Heavenly Fire he used to infuse his daughter with spirits, it was one of the most suitable alien fires for alchemists.

The demon mirage crystal nucleus gradually melted, Ling Feng carefully took out a jasper box from the material table on the side, and after a while, the crystal nucleus would melt into a high-temperature liquid state, and this kind of fire jade polished box could withstand such a high temperature.

After a while, the state of the mirage crystal nucleus began to change, and from the surface of the crystal nucleus, some high-temperature vapor was emitted, and it rose up.

Ling Feng's technique was extremely fast, his left hand covered it, emitting an icy cold air, and when it met those high-temperature vapors, it immediately turned into droplets, all of which fell into the jade box that Ling Feng had prepared earlier.

The water-based spirit that Ling Feng originally used to inject spirit was a dark moon water essence, with a yin and cold attribute, so it could produce cold qi at low temperatures, but after all, it was the true qi of the water attribute, and it could not freeze everything like the true qi of the ice attribute.

Of course, it is even less comparable to the Ice Emperor's true qi displayed by Yan Jinghong.

"It turned out to be an alternating quenching method of water and fire. ”

Su Dongling nodded again, in addition, he couldn't think of any other better way to refine this mirage crystal nucleus, but because of his own attributes, even if he wanted to use this water and fire refining method, he had to use the magic circle.

"Good boy, his techniques are so sophisticated, is he really a student taught by Yan Cangtian?"

Su Dongling frowned slightly, secretly envious in his heart, this old guy could actually find such a good seedling.

In contrast, Ling Feng was more suitable to be a poisoner than his own daughter.

"It seems that there is no need to worry about this kid at all. Yan Cangtian also shook his head and smiled, and everyone began to perform their duties.

The steps of refining the Demon Pill were slightly more complicated than the previous Ice Spirit Soul Suppression Golden Pill, but it was nothing at all for the four top alchemists present to work together.

About half an hour later, Ling Feng and the three of them had already processed all the materials and began to prepare for alchemy.

In the process of preheating the Dan furnace, Su Dongling showed excellent fire control skills, which was much more subtle than the "Heavenly Fire Dao Recipe" taught by Yan Cangtian.

From Su Dongling's technique, it is indeed somewhat similar to Su Qingxuan's technique, but it is not on the same level at all.

He is worthy of being the first poisoner of the empire!

Ling Feng took a deep breath and began to pour those already refined materials into the alchemy furnace.

Ling Feng's technique was slightly influenced by Su Qingxuan a few days ago, and he also integrated some essence into his own technique.

"Huh?" Su Dongling was secretly surprised in his heart, how could this kid's method of smelting medicinal materials be a bit like his own technique?

However, surprise is surprise, now is the critical time, Su Dongling did not distract, but continued to put one fire trick after another into the six-legged gluttonous ding.

Because it was the first time to cooperate, Ling Feng did not add some of his own ideas, and strictly followed the Dan Fang, and Su Dongling was also an extremely experienced alchemist, even if Ling Feng had the slightest deviation, he could also cooperate as much as possible, so that the medicinal liquid in the Dan furnace could be completely integrated to the greatest extent.

I have to say that cooperating with a first-class master like Su Dongling is indeed a very easy thing.

As everyone knows, Su Dongling was even more surprised in his heart, Ling Feng's young age was actually able to completely dominate the process of alchemy, and perfectly cooperate with his own fire technique.

An hour!

Two hours!

Finally, everyone's faces became slightly solemn, Su Dongling entered the last fire trick, the temperature of the Dan furnace did not rise but fell, and the Dan furnace, which was originally slightly shaking, completely calmed down at this moment.

"Ning Dan!"

Ling Feng took a deep breath and let out a low sigh, as a condensing pill seal entered the Dan furnace, the furnace lid flew high, and a nine-colored glow suddenly bloomed.

The dazzling light illuminated everyone's eyes almost without opening their eyes, Ling Feng skillfully cast the "Dragon Seal", and with a big move, the Demon Transformation Pill that flew out of the Dan furnace had already fallen into Ling Feng's hands.

It's another elixir that gives birth to spiritual wisdom!

"Click!"

The jade box was fastened, and after ten breaths, the pill could be regarded as completely accepted by Ling Feng.

"Haha, it looks like it should be the elixir that has condensed the Dan pattern!"

Hong Haotian looked a little excited, don't look at the countless alchemy he has on weekdays, but there are not many people who have really condensed the Dan pattern. Especially for high-level ancient pills, it is too difficult and difficult to condense the Dan pattern.

"Hmph, with the four of us joining forces, if we can't condense the Danwen, we can roll up the cover and go back to my hometown to farm as soon as possible. ”

Yan Cangtian laughed, took the jade box in Ling Feng's hand, and slowly opened it.

The dazzling light bloomed again, although there was no strong fragrance, but the almost dreamlike brilliance still made people sigh.

"It's really a magical elixir, the predecessor who came up with this demon pill pill is really a genius!"

Hong Haotian praised it, and saw that on top of the pill, it really condensed the Dan pattern, and it was an amazing nine Dan pattern!

Nine is an extreme technique, and nine Dan patterns mean that this Demon Pill can almost be called the best Demon Pill!

"It turned out to be a nine-pattern Qi Dan!" Su Dongling also took a deep breath, to be honest, when he was refining it himself, he had refined an eight-pattern poison pill at the highest.

Nine lines, not to mention refining, he hasn't even seen it!

"Boy, with this Demon Pill, I'm afraid that even if the Demon Emperor comes, I won't be able to tell your true identity. Yan Cangtian laughed.

"Ah, Yan Lao'er, what do you mean by this, aren't you going to the Demon Clan's Holy Land?" Hong Haotian looked confused.

"Hmph, what are you doing so much inquiry?" Yan Cangtian rolled his eyes, covered the jade box of the Demon Transformation Pill, returned it to Ling Feng, and said with a faint smile: "Boy, be careful to put it away!"

"Hmm. Ling Feng nodded, put the Demon Transformation Pill into the Naling Ring, and refined this Demon Transformation Pill, but it really took a lot of effort for himself and Yan Lao!

Because of physical discomfort, I'm afraid there are only two shifts today, and I don't know if the chapter will be written or not at night, hey......
