In the empty and slightly dim stone room, Bai Ge stood behind a stone platform for refining medicine.

On the stone platform in front of him, there was a medicine tripod on one side, and on the other side was the medicinal materials for refining the Purple Heart Barrier Breaking Pill, and not far from him, Su Lao was holding his hand and watching quietly.

The Purple Heart Barrier Breaking Pill belongs to the Four-Rank Pill, but it is not an ordinary Four-Rank Pill, but a Four-Rank Peak Pill.

In terms of efficacy, the Purple Heart Barrier Breaking Pill is somewhat similar to the Three-Pattern Qingling Pill, which is also a four-grade elixir, and they are both pills that can help the strong of the Great Dou Master improve their strength.

However, taking the Three-Pattern Qingling Pill only has a slight chance to increase the user's one-star level, although there are three kinds of Three-Pattern Qingling Pill, according to the above lines, it is divided into three grades: one-pattern, two-pattern, and three-pattern.

One of the lines has a certain chance and no side effects to increase the user's one-star strength, while the second and third lines have a chance to increase the strength of the second and three stars of the user at the level of the Great Dou Master in a short period of time, but this also has a fatal flaw.

That is, after the effect of the medicine, this pill also has a certain chance of causing the effect of the drug to backlash.

The strength of the affected will be reduced by about one to two stars.

Although there is no worry about life, but a short-term increase of two or three stars and a permanent decline of one or two stars, this is a probability that most people will not gamble.

Unless it's a life-and-death moment, I'm going to fight to the death!

And the Purple Heart Barrier Breaking Pill does not have this shortcoming, the Purple Heart Barrier Breaking Pill can also have an effect on the Great Dou Master, if you take the Purple Heart Barrier Breaking Pill, then this Great Dou Master can 100% increase the strength of one star, and there are no side effects.

And the key thing is that the same person, at the same level, can still take two pills of this pill in succession, and it will not produce much resistance.

This is compared to the improvement condition of the chance of the three-pattern green spirit pill that is also a fourth-order, and the effect of the Purple Heart Barrier Breaking Pill simply surpasses the former, and it can also take two, that is, to increase the strength of the two stars.

This kind of effect can be deservedly called the pinnacle elixir of the four grades!

But with its amazing efficacy, refining the Purple Heart Barrier Breaking Pill is also amazingly difficult.

Among the fourth-grade alchemists registered with the Alchemist Guild, there are less than a handful of alchemists who can refine the Purple Heart Barrier Breaking Pill, and even if they are fifth-grade alchemists, not everyone can refine the Purple Heart Barrier Breaking Pill.

Therefore, after seeing Bai Ge's ability to assess the elixir before refining the three grades, and then hearing Bai Ge say that he could refine the Purple Heart Barrier Breaking Pill, it was no wonder that Su Lao was so excited.

Standing in front of the alchemy stone platform, Bai Ge's eyes quickly swept over the medicinal materials on the stone platform one by one.

Purple Spirit Grass, Ascension Flower, Blood Bone Ginseng, Qi Replenishing Flower, Ambergris Orchid......

Compared to most pills that only have three main drugs, the main drugs used to refine the Purple Heart Barrier Breaking Pill have reached as many as five, and the number of auxiliary drugs is also quite large, which is related to the nature of the Purple Heart Barrier Breaking Pill that can take two pills at the same time.

With his hands quickly stretched out, he stacked the medicinal materials needed to refine the Purple Heart Barrier Breaking Pill on the stone platform into several piles in the order of input, and after everything was done, Bai Ge looked around again.

The three alchemists who were assessed together, except for Liu Quan, Xiao Yan and Xue Mei, had already refined the medicinal materials, and they were preparing for the final fusion at the moment, and after the fusion, it was Ning Dan.

Except for Bai Ge, a demon with incomparably powerful spiritual power, the most time spent by ordinary alchemists was often on the last step of the Ning Dan.

If you want to refine the medicinal liquid into an incomparably mellow pill, this is a process that extremely tests the ability to manipulate the fighting qi and the ability to master the heat.

After glancing around, Bai Ge withdrew his gaze and fell to the stone platform in front of him again.

Looking at the medicinal materials that had been piled up, Bai Ge's left hand quickly stretched out and clinged to the fire mouth of the medicine tripod, and the dark cyan green lotus earth heart fire gushed out violently, rising from the medicine tripod.

The scorching fire that surpassed all flame temperatures heated the medicine tripod in a few seconds, and after heating the medicine tripod, Bai Ge made a move with his right hand, and several medicinal herbs were put into the medicine tripod one after another, and they were burned into liquid medicine by the high-temperature Qinglian Earth Heart Fire.

Inside the medicine tripod, the dark cyan green lotus earth heart fire was constantly swallowing, because there was Su Lao watching by his side, in order to let Su Lao see the steps of refining the Purple Heart Barrier Breaking Pill more clearly, Bai Ge did not fuse the refined medicinal liquid in the medicine tripod.

Although this is more time-saving, while wrapping the refined medicinal materials one by one with Dou Qi, and constantly investing in the refining of new medicinal materials, this kind of fine Dou Qi control ability is not something that ordinary alchemists can do.

Therefore, in order to let Su Lao see the steps of refining the Purple Heart Barrier Breaking Pill more clearly, Bai Ge chose to take out one small jade bottle after another, introduce the refined medicinal liquid into the small jade bottle, and then use his fighting spirit to carve the name of the medicinal material for refining the medicinal liquid in the small jade bottle.

Purple Spirit Grass, Ascension Flower, Blood Bone Ginseng......

The medicinal herbs were refined one after another, and then they were introduced into small jade bottles and put away.

From the main medicine to the auxiliary medicine, after the refining was completed, Bai Ge weakened the strange fire burning in the medicine pod, and then with a move with his right hand, he put the refined main medicine liquid into the medicine pod.

Inside the medicine pod, the dark cyan green lotus earth core fire was still slowly burning, Bai Ge used his fighting energy to control the fusion of the medicinal liquid, and at the same time used his spiritual power to accurately perceive the changes in the medicinal properties of the medicinal liquid, interfering with the wood attribute physique, and changing the temperature of the alien fire at the same time.

Under Bai Ge's control, the liquid medicine of the five main medicines finally fused into a purple liquid mass, and then it was reintroduced into a new small jade bottle, and then the auxiliary medicine liquid was fused, and the steps were the same.

After completing the steps of the fusion of the main drug and the auxiliary drug solution, Bai Ge once again put the fused main drug liquid and the auxiliary drug liquid into the medicine tripod, and began to finely control and control the fusion of the main drug and the auxiliary drug liquid after fusion.

Because refining requires more medicinal materials, this step is the most difficult for ordinary alchemists.

Therefore, after Su Lao, who was watching from the sidelines, found that Bai Ge had reached this step, he began to pay more attention to the changes in the medicinal liquid in the medicine tripod.

Under Su Lao's gaze, the two groups of medicinal liquid finally collided and fused together, and then the flames in the medicine pod rose and weakened, and continued to repeat.

As the flames continued to change, the color of the fused potion began to change, from the original dark purple to light purple, glowing faintly.

In the end, after the fusion of the liquid medicine was completed, Bai Ge began the last step - Ning Dan!

This step can be said to be the most difficult level for ordinary alchemists.

Because once the Ning Dan appears to be wrong, the refined pill is not the pill, but the ointment or powder, which will greatly reduce the efficacy of the pill, and it is considered an unqualified pill.

But for Bai Ge, who was extremely strong in fighting spirit and mental power, this step was the easiest.

Under the control of powerful spiritual power, Ning Dan would hardly make any mistakes in Bai Ge at this step.

The lilac liquid slowly rotated in the medicine pod, and under the burning of the green lotus earth's core fire, the liquid gradually turned into ointment, then became semi-solid, and finally became a pill completely!

And on the way, the elixir assessed by Xue Mei and Xiao Yan's second-grade alchemists was finally refined!

However, because of Bai Ge's influence, Xiao Yan's study of alchemy only began after joining Canaan Academy.

In other words, I only studied for half a year, and I didn't have a different fire like in the original book.

Therefore, although Xiao Yan's alchemy talent is higher than that of Xue Mei, Xiao Yan's current alchemy level is far inferior to Xue Mei.

Therefore, in the assessment of the alchemist, Xue Mei completed the refining of the second-grade Vein Protection Pill faster, followed by Xiao Yan, who refined the first-grade Fire Condensing Pill.

However, because Su Lao was still watching Bai Ge refining the Purple Heart Barrier Breaking Pill, Xiao Yan and Xue Mei were not stupid, so naturally they would not bother Su Lao at this juncture.

Therefore, after refining the elixir, he waited silently behind the stone platform.

On the side, I saw that Xiao Yan and Xue Mei had already finished refining, but their own qi dispersion had not yet been completed.

Seeing that the time was about to end, Liu Quan couldn't help but suddenly become anxious.

But at the moment when Liu Quan was anxious, a familiar voice suddenly came from not far away.

"Old Su, Purple Heart Barrier Breaking Pill, it's done!"

Hearing the voice, Liu Quan couldn't help but tremble his hands suddenly, the flames and fighting qi in the medicine tripod suddenly changed drastically, and the mellow medicinal liquid that was condensing the pill almost fell.
