"At this time, it is especially necessary to control the temperature, not only to force the venom out, but also not to evaporate it!"

As time passed, those poisonous herbs also slowly and completely melted into dark green juice, flowing in the Dan furnace.

"The next step is to mix the liquid medicine, which is also very important. On the one hand, the ratio of the liquid medicine must be right, otherwise the properties of the elixir may change. The abolition of the pill is only the best ending, and there may even be other types of elixirs, some of the elixirs that have been inspired in the history of alchemy are like this, but it is more likely to become other elixirs with side effects, such as the elixir that saves people's lives to the poison pill that seals the throat when it sees blood. Therefore, the proportion of liquid medicine must be mastered. ”

After speaking, Zhu Yi lifted the corner of the tripod lid, quickly stuffed the origin aura released before from the gap, and then quickly closed the tripod lid.

Although the Ten Thousand Poison Herb will only be poisoned if it is taken, but now the elixir is still being refined, who knows if the venom will have any changes, if the lid is opened too much, it will be troublesome if you accidentally hurt people. Even if you don't consider this, you have to consider the preservation of the medicinal properties of the liquid medicine, and if you open the lid too much, the medicinal power may spread.

After the aura entered the Dan furnace, Zhu Yi carefully controlled the aura to disperse, and the medicine wrapped in the middle fell down drop by drop, and Zhu Yi carefully observed the changes in the venom with his divine sense.

When the medicine fell into the venom, the otherwise calm venom began to tumble as if it were boiling. However, if you look closely, you can see that with the addition of the medicine, the dark green venom began to fade gradually.

At this time, Zhu Yi's palms were also covered with a thin layer of demon phoenix nirvana flames, like gloves. Then he directly held the Dan furnace with both palms and began to shake it gently.

The medicinal liquid in the Dan furnace began to rotate, Zhu Yi's hands shook gently in a strange trajectory, and the two medicinal liquids inside gradually fused together, and the dark green venom began to become lighter and lighter, gradually changing to an almost colorless direction.

In fact, there are many methods of alchemy, and the most common is to use aura to manipulate various alchemy techniques into it to complete the refining of the elixir. The advantage of this method is that it is not easy to make mistakes, and as long as the alchemy technique is proficient enough, it can generally be successfully completed.

And Zhu Yi is now using the oldest and most primitive refining method, which is no different from ordinary people boiling medicine. This method is much more troublesome than the alchemy technique, but the most respected refining method on the Danding spectrum is this refining method.

Because this refining method can make the best mixture of medicinal properties in various medicinal materials, and manual operation can adjust the refining according to different situations. You can even use some techniques to re-separate the medicinal power and reduce the production of waste pills. Especially in the case that there is only one medicinal material for refining, there is absolutely no room for loss, if there is a skilled boiling technique, the waste pill rate will be reduced to a minimum.

In addition, some high-grade pills, if they are refined with alchemy techniques, there may be thousands or even tens of thousands of hands in the recipes alone. Even if you have the reputation of a sixth- or seventh-level alchemist, you may not be able to guarantee that there will be no mistakes in these thousands of hand techniques.

But the primitive boiling technique can do it, it can better control the situation inside the Dan furnace, and some top alchemists in ancient times preferred to use this method rather than the alchemy technique.

Soon, bursts of medicinal fragrance emanated from the Dan furnace, and a smile appeared on Zhu Yi's face, if there were no accidents, this furnace of pills would be considered a success.

"Next is the Ning Dan, the reason why the pill is pill-like is because the alchemists all believe that the image of a perfect ball symbolizes the meaning of perfection and fullness. And in fact, the more top-level the elixir, the closer its form is to a perfect spherical shape, which is also the shape of the world before Hongmeng opened the world. Therefore, Ning Dan is a very important step, forming a full and complete pill, which can be regarded as a real refining success. ”

Zhu Yi had already put the Dan furnace on the ground again, put his hands in front of him, and after breathing the breath in his body, his hands quickly turned into phantoms, and the Cheng Dan recipe recorded in the Dan Ding spectrum was quickly beaten into the Dan furnace by him.

Runes lit up above the Dan furnace, and the medicinal liquids that had been perfectly fused began to churn, floating like droplets, and then quickly combined together, and finally turned into prototypes of pills the size of a dragon's eye.

"Cheng!" Zhu Yi shouted violently, and the light of his fingertips slammed into the Dan furnace. This Cheng Dan and even the collection of Dan are completed with hand formulas, and each alchemy school's Cheng Dan hand recipe and Dan collection hand are different, the Dan Ding spectrum recorded is naturally the top, as long as Zhu Yi's cultivation is enough, it is not a problem to complete the Cheng Dan and the collection of the Emperor Dan.

With the light entering, the prototypes of the pills also became more condensed, and the slight mist that was originally formed by the evaporation of the flames in the Dan furnace was also integrated into those pills at this time, and there was nothing in the Dan furnace except for the pills floating in the air.

"Get up!" Zhu Yi's eyes flashed, the index finger and middle finger of his right hand were together, and he lifted them into the air, and the lid opened again, and the pills that shone with white light rushed out.

The jade and the following pills are all called death pills. Because after it is refined, it rolls down into the Dan furnace like jelly beans, without a trace of spirituality. And the spirit pill above is called the elixir, because it has already given birth to a trace of spirituality, and even knows that it escaped like just now, so it needs to receive the pill trick.

With a wave of Zhu Yi's right hand, the aura transformed into a big hand, directly grasping those pills in the palm of his hand.

"It worked. Zhu Yi withdrew his aura hand, and more than twenty Ten Thousand Poison Invulnerable Pills appeared in his palm.

"So little?" Watching Zhu Yi take out a jade bottle and put these pills in it, Feng Wan pursed her lips and said.

Zhu Yi couldn't help but roll his eyes when he heard Feng Wan's words, and said, "Grandma, do you know that if my Cheng Dan rate is seen by those ordinary fifth-level alchemists outside, it will be shocked." Under normal circumstances, it would be good for them to have half my success rate. ”

Alchemy is inherently a very troublesome job, and the output and input are extremely disproportionate. Like the amount that Zhu Yi had prepared for trying to refine just now, it was already good for an ordinary fifth-level alchemist to try to form ten pills, not to mention that he could condense into more than twenty pills at a time like he was now.

In Zhu Yi's repeated explanations, everyone realized how difficult alchemy was. However, these people all patted Zhu Yi on the shoulder, and said very unkindly that since it was so difficult, then the matter of alchemy would be handed over to Zhu Yi to solve alone, which made Zhu Yi half angry.

There are about a hundred or so Ten Thousand Poison Herbs left, which is enough for Zhu Yi to refine a lot of Ten Thousand Poison Invading Pills, but he has just refined and consumed a lot of spiritual energy, so he has to take a break before he can continue.

After refining more than two hundred Ten Thousand Poison Invading Pills, everyone was basically adjusted to their peak state, Zhu Yi distributed twenty Ten Thousand Poison Invading Pills to everyone, and then headed in the direction of Tongtianmen, because they also knew that they couldn't delay any longer, and they had already sensed that there was a breath in the poisonous swamp.

From the previous battle with the Fire Lin to the time to rest the team, some of the cultivators who moved faster had already obtained enough Ice Cream Flowers and rushed towards the poisonous swamp. Because up to now, the Heavenly Dao Rubik's Cube has not prompted that someone has already broken through the Tongtian Gate, which makes these cultivators' hearts full of hope again, maybe this time the first one to pass through the Tongtian Gate will be themselves?

What made Zhu Yi and the others a little fortunate was that although Tang Lianyue, Huolin and others had scared away the poisonous insects and beasts in that area before, after these few days of silence, those poisonous insects and beasts returned to their original living space. Even if it is a spirit animal, it can't get rid of the habits of primitive creatures before it has fully opened its spiritual intelligence, and it will definitely not choose to migrate without major changes.

Therefore, those cultivators who broke into the poisonous swamp were all attacked by these poisonous insects and beasts, and the ordinary poisons were better, but those spirit beasts brought them great trouble.

These ordinary cultivators were not as lucky as Zhu Yi and the others, and there were strange fires that could make these poisons afraid. The toxins of some poisonous substances were basically incurable for these ordinary cultivators, so those cultivators who rushed to enter the Poisonous Swamp almost all underestimated the horror of the Poisonous Swamp, and they all collapsed, killing and injuring one after another.

And Zhu Yi and the others, who have ten thousand poisons that do not invade the pill, seem to be much more relaxed, even if Zhu Yi and Murong Xiaoxiao do not show their strange fire breath, those poisons can smell the deadly breath and dare not step forward. Since the Ten Thousand Poisons Immortal Pill can dispel ten thousand poisons, these poisons are also natural nemesis, but Zhu Yi and the others will not be so extravagant as to throw this Ten Thousand Poisons Immortal Pill directly into the mouth of the poison.

This idea was still put forward by Feng Wan, and only her brain, which was full of all kinds of strange ideas, could think of such a strange method, and even Zhu Yi was wondering, if the sixth-level spirit beast she encountered was also highly poisonous, would she throw one of the Ten Thousand Poison Invasive Pill over to it as candy, but she would be able to directly "poison" the other party to death.

The closer they got to Tongtianmen, the more cautious Zhu Yi and the others became, because according to the Ancient Thunder Eagle, the aura of that sixth-level spirit beast was getting stronger and stronger, and I was afraid that it was around here.

But what made Zhu Yi and the others feel very strange was that before they stepped into the Tongtian Gate, they didn't see the figure of the sixth-level spirit beast.

"Could it be that you are asleep?" With the flash of light, everyone submerged into the Heavenly Gate together, and such a nonsensical thought flashed in Zhu Yi's mind, otherwise how to explain that this sixth-level spirit beast has not appeared.

However, when they entered the world inside the Tongtian Gate, this doubt of Zhu Yi and the others was completely solved, because when they saw the world in front of them clearly, they couldn't help but feel numb in their scalps. Even Murong Xiaoxiao, a bold character, couldn't help but stand behind Zhu Yi, like a little girl, holding the corner of Zhu Yi's clothes with one hand.

A hoarse voice rang out in the space.

"Welcome to the world of this seat!"
