After returning to the room, Ji Yun looked excited, and took the Dan furnace to study it in the room.

According to the records of the longevity formula, the quality of the Dan furnace determines the probability of becoming a Dan to a certain extent, and the key factor of becoming a Dan is also the technique of the person who makes the Dan.

The alchemy technique is divided into three major schools, one of which is the technique of the Immortal Palace, called the Immortal Stream, and the elixir of the Immortal Stream is mainly based on increasing cultivation and supplemented by healing;

The second is the alchemy technique of the demon clan, which is called the Luminous Stream, which is famous for its magic pill and body pill;

The third is the Dan Dao technique of the demon clan, which is called the Demon Emperor Flow, and the Dan Dao of the Demon Emperor Flow is the most respected by the world.

The three Dan Dao are all based on the Dan Dao volume of the "Seven Strategies", and some people say that if someone integrates the three Dan Dao, they will reproduce the Dan Dao chapter of the "Seven Strategies".

Speaking of which, I have to mention the "Seven Strategies", according to the records in the longevity formula, "Seven Strategies" is the first strange book of the Haotian world.

This book has a total of seven volumes, each of which has the unfathomable power of ghosts and gods, namely the Immortal Scroll, the Dan Dao Scroll, the Refining Weapon Scroll, the Formation Scroll, the Imperial Beast Scroll, and the most mysterious Dao Law Scroll and the Most Holy Scroll.

Ji Yun had no way of understanding this, and at this time, he was completely immersed in the alchemy technique of the Hall of Eternal Life, that is, the Immortal Stream.

The alchemy technique of the immortal stream is the most widely spread and the most popular method among the human race, and the vast majority of cultivators can have the opportunity to be familiar with its alchemy technique, but the cultivators who can really comprehend the Dan Dao and thus refine the pill are still very few, and there are only a very few talented people.

These people who can integrate the immortal flow, the refined pills are also divided into several grades, and the medicinal effect of the refined pills can be respected as Danjun if the effect is one to three percent, which is also the realm where the vast majority of alchemists are located.

The higher level is called the Dan Master, this realm can improve the medicinal effect of the pill to four to six layers, and the Danzun, which is rare in the Dan Dao, the entire Haotian world is not a hand, these few can refine the medicinal effect of the pill at more than seventy percent, or even reach ninety.

Ji Yun looked at the alchemy technique in his mind, stunned, until three hours later, Ao Yiyi's voice sounded outside the house.

"Bastard, do you know how to do alchemy."

Ji Yun came back to his senses, a bright light appeared in his eyes, and then said: "Yes, but as stated in the immortal stream, alchemy requires Danhuo, where can I find Danhuo, I can't use the fireball technique to alchemy." ”

After Ji Yun finished speaking, his eyes showed anticipation.

Sure enough, as soon as Ji Yun's words fell, a white light enveloped Ji Yun and disappeared from the room, Ji Yun only felt that his eyes were black, and then appeared in another room.

"Stinky boy, this is the Dan room of the Hall of Eternal Life, there is a ground fire in the middle of the room, just put the Dan furnace on it, in the box around it, there are all the alchemy materials from the condensation period to the Xia Xuan realm, if you can't refine the pill, I will lock you in it and never be born." Xiao Bai's resentful voice came from Ji Yun's ears.

Ji Yun was helpless, secretly saying that his cow might have blown up, and then looked at the Danfang carefully.

The Danfang is extremely square, surrounded by wooden shelves, on which wooden boxes of the same size are displayed, and the names of the medicinal materials in the boxes are written.

There was a pit in the middle of the room, it was dark and bottomless, and there was a futon next to the pit.

"Xiaobai, the Dan furnace is sent in."

As soon as Ji Yun's voice fell, a quaint eighth-order Dan furnace was suspended above the black pit.

"According to the elixir of longevity, the first step in this alchemy is to lead the earth to the fire and warm the pill furnace, which is to prevent the furnace from exploding."

Ji Yunpan sat on the futon, pinched the trick with both hands, and carefully activated the earth's fire.

"Poof"

A wave of heat came from the surface, and the pitch-black pit was instantly filled with blue fireworks, shining on Ji Yun's face, making it look very weird.

Ji Yun's eyes brightened, and then he waved his hands towards the Dan furnace.

"Buzz"

The Dan furnace was shocked, and then it was quaint, and the black Dan furnace became snow-white and translucent, as if it was mutton fat jade, and everything in the Dan furnace was presented in the eyes.

"Hey, hey"

Ji Yun smirked, and then controlled his weak divine sense, took out the medicinal materials he needed from the box, and put the medicinal materials into the Dan furnace in turn according to the order of medicinal materials recorded in the longevity formula.

The herbs that Ji Yun put into the Dan furnace in turn slowly underwent strange changes, decomposing, fusing them, condensing them, dispersing them again, and fusing them.

Ji Yun watched the Dan Furnace herb gradually transform into an elixir, and muttered, "It's that simple? ”

At this moment, the medicinal herbs in the Dan furnace, which were gradually transforming into pills, began to beat violently, and then emitted a dazzling light.

"Boom"

A huge sound exploded in Ji Yun's ears, and suddenly his ears roared, his head was dizzy, and clouds of black smoke floated out from the Dan furnace, emitting a foul smell.

At the same time, Ao Yiyi, who was holding Xiaobai in her arms in the grass house, heard a loud noise, and was so frightened that she almost put Xiaobai in her arms on the ground.

"What a sound."

Ao Yiyi was shocked.

"It's okay, you keep nibbling on the carrots." Xiaobai was very calm, as if he had expected it.

Speaking of Ji Yun in the Dan room, his appearance was very embarrassed at this time, his hair was scattered, his eyes were scattered, his face was black and swarthy, and only a pair of eyes were outside, revealing shock and puzzlement.

"It's blown up, the pill is blown up." Ji Yun muttered to himself, and was shocked at the moment when the pill exploded.

"You should be glad that I gave you the Eight Rank Pill Furnace, otherwise it wouldn't be as simple as dynamizing pills." In Ji Yun's ears, there was a joking voice from Xiaobai.

Ji Yun came back to his senses, his eyes were very resentful.

"Xiaobai, you cheat me."

Outside the Dan room, a smile appeared on the corner of the little white mouth in Ao Yiyi's arms.

"You cheated yourself, hehe."

Ji Yun was helpless, he bragged first.

"I don't believe it, I still have to practice this Dan."

Ji Yun was ruthless, checking in his mind why the alchemy was blowing up.

It is noted in the longevity recipe that when refining the pill, you must always pay attention to the size of the earth fire, and you must also control the time when each herb is put into the furnace, otherwise it will cause the fryer or refine the waste pill, which Ji Yun did not pay attention to just now.

"I see." Ji Yun came to his senses and began to refine the elixir again.

While he used his divine sense to control the herbs to fly into the Dan furnace, he also divided a part of his divine sense to control the earth fire, and the originally weak divine consciousness made Ji Yun exhausted under such a double-line operation.

Seeing that the herb was transforming into an elixir again, Ji Yun's heart became apprehensive again.

"Not good."

A white light flashed, and a roaring sound appeared in Ji Yun's ears again, compared to just now, this time Ji Yun was prepared, but it was still roaring in both ears.

"How can this be, I obviously followed Dan Fang's complaint, step by step and cautiously, how could I still fry the oven." Ji Yun was puzzled, and looked at the precautions for alchemy in his mind again, but no matter how he compared, there was no mistake in his operation.

"Maybe it's because the details are not handled well, but you'll know after a few more attempts."

So Ji Yun started again, following the steps to control the earth fire and add herbs.

"Boom"

Seeing that the pill was about to take shape, without exception, it exploded again.

"That's why." Ji Yun shouted in his heart, very puzzled.

"Boy, if you do alchemy like this, you have to refine yourself to death."

Just when Ji Yun was wondering, Xiaobai's voice came again.

"Xiaobai, you said that I was refining pills completely according to the Dan formula, why did I still blow up the furnace?"

"I don't know how to do alchemy, but looking at the herbs you put into the Dan furnace, some of them are herbs from the Lower Xuan Realm, and you are in the Qi Condensation Period, and if you want to refine the pills of the Lower Xuan Realm, I'm afraid it's not appropriate." This time, Xiaobai did not ridicule Ji Yun, but seriously pointed out what was wrong with Ji Yun now.

After listening to this, Ji Yun patted his head and said carelessly.

Ji Yun smiled bitterly, found a Gathering Spirit Pill suitable for the first layer of Qi Condensation in his mind, began to analyze the pill formula, and then began to refine the pill again.

This time, Ji Yun was more careful to control the size of the earth fire with his divine sense, and at the same time used his divine sense to control the herbs flying into the Lu, and his eyes were constantly observing the situation of the herbs in the Lu.

About a quarter of an hour passed, and the herbs in the house turned into pills.

At this moment, Ji Yun's heart was in his throat, and he was inexplicably nervous.

"Squeak"

At the moment when the elixir was formed, the elixir in the furnace cracked open and turned into countless fragments.

"Haha, it didn't blow up this time."

Although the pill was broken after it was formed, it was much better than just now, and Ji Yun was inevitably happy.

"If one furnace doesn't work, it's ten furnaces, and if ten furnaces don't work, it's a hundred furnaces, and if I don't believe it, I can't refine it." Ji Yun secretly competed and began refining again.

Unconsciously, Ji Yun had refined more than a dozen furnaces of pills just now, but every time the pills were shattered in a split second after they were formed.

At the same time, with more than a dozen double-line operations of divine consciousness, Ji Yun's divine consciousness slowly began to condense, and a divine consciousness that was more than thirty percent stronger than before permeated the Danfang.

Although this divine sense was very weak in the eyes of the Xuan Xuan Realm, it was extremely extraordinary to appear in a person with a sixth-layer aura, which gave it infinite possibilities.

Ji Yun was not discouraged, one furnace after another of refining pills, gradually his eyes became red, as if he was about to drip blood, and his divine consciousness gradually became trance-like and uncertain.

Outside the Dan room, in the valley, it was already a sparse moon, Ao Yiyi sat on the futon with a small bag in her arms, closed her eyes and fell asleep, Xiaobai, who had already closed her eyes, opened her eyes at this time, and a touch of relief appeared at the corner of her mouth.

"This kid is actually enlightened, which is not bad."

After Xiaobai finished speaking, he slowly closed his eyes again, and outside the grassland, the entire valley was extremely quiet.

In the Dan room, Ji Yun fell into a strange state at this time, and all the alchemy actions were like instincts, flowing smoothly without the slightest stagnation.

His divine consciousness was also more condensed, more than twice as much as before, and this kind of divine consciousness was extremely terrifying in the condensation period.

The Chinese herbs in the Dan furnace gradually took shape towards the Dan medicine, and a round and transparent Juling Pill was formed, which was not broken this time, quietly floating in the Dan furnace, exuding an attractive aroma.
