The Black Dragon Furnace, which became famous in the cultivation world with Li Madjun back then, refined an unknown number of Dao-level pills. If it weren't for the end of the Dharma era, when all living beings were prisoners and the realm could not break through to the divine realm, this Dan furnace would probably refine a large number of divine pills, even the legendary Emperor Pill.

When Chu Duan got the Black Dragon Furnace, the Black Dragon Furnace was only a shell, and the machine spirit had already been wiped out with the failure of Li Maarjun's alchemy, and the grade had also fallen because of it. Now the grade of the Black Dragon Furnace has not only been upgraded to the level of top-grade and low-grade divine soldiers, but also has the soul of a soldier, and many extremely high-quality divine pills have been refined in the hands of Chu Duan and Da Heitian.

The corners of Li Annan's eyes twitched slightly, it was not an idle person to be able to rank first among the junior Dan Dao Divine Masters of the Dan Immortal Palace, he had already sensed the extraordinaryness of the Black Dragon Furnace.

The Dan Furnace is the second life for the alchemist, and if this Dan Furnace is really owned by the Heaven Tribulation Sect Master, the Dan Dao attainments of the Heaven Destroying Sect Master may not be trivial.

After calming down, Li Annan began the first step of alchemy, and the Annan furnace slowly floated into the air, and a vermilion divine bird bathed in flames appeared behind Li Annan. The Vermilion Divine Bird has two pairs of wings, the first pair of wings can stretch out more than ten zhang, and the second pair of wings is only half the size of the first pair of wings.

"Four-winged vermilion fire!" a monk whispered.

The four-winged vermilion fire is not the natural fire born of heaven and earth, nor is it an artificially refined flame, but the natural divine fire on the four-winged vermilion bird. Li Annan accidentally fell into the nest of the four-winged vermilion bird when he was young, but instead of falling, he brought out an egg of the four-winged vermilion bird.

Later, the four-winged vermilion bird was hatched by Li Annan, grew up with him day and night, and became his natal divine bird, and the four-winged vermilion bird, which was naturally good at resisting fire, became his best helper for alchemy.

The four-winged Vermilion Bird gently flapped the two pairs of wings, and the feather-like four-winged Vermilion Fire slowly rotated around the Annan furnace, and the furnace temperature gradually increased.

The first medicinal herb Chiba vine fell into the Annan furnace, and Li Annan's slender ten fingers kept changing, and hundreds of stars were born in his hands and fell into the Dan furnace.

"Starry Medicine Refiner!"

This is the Dan Dao secret technique created by a close emperor of the Danxian Palace, the secret art vision is like thousands of stars, and after a while, a verdant medicinal liquid flies out of the Dan furnace and falls aside.

"That's right, ninety percent of the purity of the potion. Dan Xian Hall Chongming Dan Huang stroked his beard and smiled.

The final quality of the pill is inseparable from the purity of the medicinal power of each medicinal material, if the purity of the medicinal material is not high, the quality of the final pill will not be high.

The second medicinal material, purple bamboo roots, are put into the Dan furnace, and the purple bamboo roots are like the rhizomes of bamboo, which can be one foot long, and the surface flows with purple light.

Li Annan's hands were sealed, the thumb of his right hand was clasped in the palm of his hand, and the other four fingers were together. The middle finger of the left hand is clasped on the thumb, and the other three fingers are cocked, like a phoenix holding its head high.

The dragon roared and the phoenix roared, and a fire dragon and a fire phoenix flew out and flew up and down around the Dan furnace, and the fire dragon and the fire phoenix spit out fire light to refine the medicinal power in the purple bamboo root, and soon a ball of purple jade-like medicinal liquid flew out.

"Dragon and Phoenix Great Refining!"

Another kind of secret that the Danxian Hall does not pass on, this kind of Dan Dao secret technique is difficult to refine, and even the disciples of the Danxian Hall who can master this technique in each generation are less than a hand.

Next, the red fox flower, the blue sea moss and other medicinal materials fell into the Dan furnace one after another, and Li Annan used a different Dan Dao secret technique for each medicinal material, which dazzled the alchemists.

"What is the Heaven Tribulation Sect Master doing, why hasn't he started alchemy?"

While watching Li Annan's alchemy, everyone also noticed the Great Black Heaven, the leader of the Heaven Tribulation Sect, but found that the Great Black Heaven did not make a move for a long time, but was observing medicinal materials such as Chiba vine and purple bamboo root.

"Could it be that the Heaven Tribulation Sect Master doesn't know how to refine the pill at all, or knows that he is not Li Annan's opponent, so he simply doesn't make a move, so that he can save some face. If the alchemy fails, or even the final explosion of the furnace, it will be a loss of face. The crowd was talking.

But the people who are talking about it are all monks who are not highly cultivated, and those who have cultivated profoundly, especially those who have attained extremely high Dan Dao attainments, have a different color on their faces. They saw transparent silk threads flying out of the Great Black Sky and submerging into the medicinal herbs.

Beings with profound cultivation or extremely high attainments in the Dan Dao recognized that it was a secret technique of the Dan Dao that had never appeared in the cultivation world, and the specific effect was unknown, but it was extremely extraordinary.

Only a very small number of Heaven Tribulation Sect alchemists knew that it was a secret technique of the Dan Dao called Tiannong Medicine Hand, which could explore the medicinal properties of each medicinal material and analyze the effect of the medicinal materials in detail.

Each medicinal material has its own unique medicinal properties, and each medicinal material in each medicinal material is not the same, and factors such as year, growth environment, picking method and so on will have a certain impact on the medicinal material itself.

It's like the same human race, but the human race is hundreds of millions of sentient beings, and each human race is different, with various personalities and joys, sorrows, and sorrows, in fact, the same is true for medicinal materials.

It's just that no alchemist would pay attention to these in the past, they need to be the medicinal power in the medicinal materials, and the same medicinal materials must have the same medicinal power, as long as the required medicinal power is refined.

Why is it very difficult for the alchemists of the Tianjun Great World to refine the perfect quality pills, they can't control it at all, and they can only get one or two perfect pills once in a while by relying on luck? In fact, this is one of the reasons.

According to Dan Weng, every herb, even the most inconspicuous herb, has its own unique temperament. Even the temper of the medicinal herb is not clear, and if you directly start refining its medicinal power, you will naturally not get a perfect result.

Dan Weng's Dan Dao attainments were unimaginable, and Chu Duan realized the Tiannong Medicine Skill from the Dan Dao taught by Dan Weng, so as to dig deep into the medicinal properties and temper of each medicinal material, so as to control the success rate of refining the perfect quality Dan Medicine.

It was only after Li Annan had processed all the other medicinal materials and refined the required medicinal power that Da Heitian began to start alchemy, and as soon as he made a move, everyone was in an uproar, and he put all the medicinal materials into the black dragon furnace.

"This ...... Is the Heaven Tribulation Sect Master crazy?"

"You see, I said a long time ago that the Heaven Tribulation Sect Master is not Annan's opponent at all, and now that he has given up on himself, it is strange that so many medicinal materials are thrown into it together and not turned into ashes. ”

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

For the sake of the alchemist's ability to refine the medicinal power, most of them are one kind of refinement, and the more powerful alchemists or the refined pills will refine many kinds at the same time when they are easier than the alchemists, but no one has ever dared to refine the pills of the same level as their own attainments for the first time and throw all the medicinal materials into the Dan furnace together.

In this way, the alchemist cannot refine the medicinal properties of all the medicinal materials at the same time, and if there is a slight delay, it is likely that the medicinal materials will turn into ashes in the Dan furnace, and even the medicinal properties of various medicinal materials will collide with each other and directly fail in alchemy.
