The entrance to the Earth Fire Vein of Chixiao Peak.

Lei Luo didn't go to the public hall this time, but stayed at a reception place, because next considering that the elixir he was refining was a bit special, he needed a relatively quiet place that would not be disturbed.

"Our alchemy room in Chixiao Peak has three distinctions: low-level, intermediate-level, and high-level, with ten contribution points a day for low-level and fifty contribution points for intermediate-level a day, and high-level is not open to Qi cultivation disciples!"

The receptionist here is a foundation building monk from Chixiao Peak, and he explained to Lei Luo endlessly, although the person in front of him is an outer disciple, but he is stationed here, and the work that should be done still has to be done.

"Senior Uncle, is there any difference between these three, and why are high-level disciples not open to Qi cultivation disciples?" Lei Luo thought for a moment after hearing this, and then asked.

After all, it is related to his own foundation, so he also wants a better alchemy room, plus he still has more than 6,000 contribution points in his hand, and he will naturally not use a good one.

"The alchemy room of our Chixiao Peak is closer to the depths of the Earth Fire Vein than the public hall outside, and the closer the fire is, the stronger it becomes!"

"And according to the degree of penetrating into the Earth Fire Vein, it is divided into three levels: low, medium and high, as for the alchemy room at the highest level, it is close to the center of the Earth Fire Vein, and the Qi Cultivation Disciple can't stand the heat of that Earth Fire, let alone alchemy at that time, it is a question of whether he can stand up and come out," the senior uncle replied according to the regulations.

However, this person had a slight look of sarcasm when answering Lei Luo's question, with his experience, Qi cultivation disciples were generally alchemy in the public hall, and occasionally a few disciples of the Five Peaks might use the low-level alchemy room.

And Lei Luo looked like an outer disciple, and when he thought of the poor value of the outer disciple, he showed a trace of boredom with Lei Luo's problem of digging the ground.

After all, he is a foundation building monk, and he needs to explain to an outer disciple that this is a matter of losing his identity, and he is secretly planning in his heart, if the other party is entangled, he will give the other party a little threat.

After hearing this uncle's explanation, Lei Luo thought about it slightly, revealing a hesitant look, which made the other party even more despised, and almost scolded Lei Luo for being a poor boy.

"Then in that case, I'll use the intermediate alchemy room, I'll use it for four months, Uncle Shi, please collect contribution points." ”

After thinking about it, Lei Luo decided to use the intermediate alchemy room with the best current conditions.

Fifty contribution points a day, four months is six thousand contribution points, when the reception uncle really took away six thousand contribution points from Lei Luo, he couldn't believe it, and his mouth was even more open and not closed.

But in the end, he still gave Lei Luo a forbidden token, and then sent the kid in front of him away.

"In the middle alchemy room, the ghost knows what you want to refine, but just you, a Qi cultivator, what can you refine in four months!"

Lei Luo naturally didn't care about this, he walked towards the depths of the Earth Fire Vein, and then walked to the door of a secret room with No. B 3 written on it, and took out the forbidden token and pressed it lightly on the door, and opened the alchemy room.

After carefully looking at his alchemy environment in the next four months, he found that this alchemy room was not small, and the alchemy furnace here was more than twice as large as that in the public hall, and the quality was higher.

"It's just different for what costs a contribution point, you get what you pay for!" Lei Luo said with some emotion.

The alchemy furnaces outside are some popular low-level magic weapons, and the quality of this alchemy furnace is close to that of medium-grade magic weapons, so if you think about it, the success rate of the pill is a little higher.

And in this alchemy room, there is also a resting quiet room, there are two rooms in the front and back, the outside is alchemy, and the inside is for the disciples who are tired of alchemy to rest, and it is quite thoughtful.

"Since everything is ready, let's start, if you succeed in alchemy early, you can build the foundation early, and the time is limited, so you can't waste it!"

Lei Luo sorted the medicinal materials of the Sword Heart Pill and put them into a storage bag, and then took out a storage bag and took out twenty copies of the medicinal materials from it, which were used to refine the modified version of the Sword Heart Pill.

Because the original version of the Sword Heart Pill was too challenging for himself, he first prepared twenty revisions for practicing without fighting an uncertain battle, after all, the process of the two pills was similar, but the main flavor herbs were replaced.

After dividing the twenty medicinal herbs, Lei Luo went through the refining process of the revised version of the Sword Heart Pill several times in his mind and confirmed that he was proficient in every step before activating this alchemy furnace.

After feeling that the firepower of this alchemy furnace was several times that of the hall, Lei Luo cautiously started the first refining.

There are a total of twenty-five kinds of medicinal materials in the revised version of Jianxin Dan, among which the main medicinal materials are replaced from Jianxin Grass to a second-class medicinal material called Gladiolus, although the medicinal properties are not as strong as Jianxin Grass, but it is not comparable to ordinary medicinal materials.

Therefore, there are as many as ten kinds of auxiliary medicinal materials for gladiolus alone, and these medicinal materials are specially used to neutralize a sword-shaped aura faintly contained in gladiolus.

Lei Luo was running the Divine Cultivation Technique, while staring intently at the reaction of the medicinal materials in the alchemy furnace, and then added other medicinal materials one after another, and only after confirming that there would be no overreaction in the alchemy furnace did he continue to put in the medicinal materials of the next process.

When the medicinal materials were just more than half placed, the first medicinal materials were completely scrapped, looking at the medicinal residue in the alchemy furnace, his face remained unchanged, and then he cleaned up the alchemy furnace, and then closed his eyes and thought.

The first medicinal material failed at the stage of releasing the medicine, but Lei Luo, who had already been mentally prepared, went through all the steps just now, and there was no problem before which step, and after he had done it and sorted out all the problems, he started refining the second part.

Just now, for the first time, he summed up that in the process of discharging the medicine, there was a medicinal herb that exceeded the slightest trace when it was placed, but the ratio of the two neutralizing drugs was unbalanced, so a series of reactions were produced, and finally failed.

This time, he was particularly careful and cautious in the process of placing the medicine, and strictly followed the operation, for fear of wasting the medicinal materials again.

Until he took out the gladiolus flower, there was no problem with the medicinal materials in the alchemy furnace, this time Lei Luo looked at the main medicinal materials in his hand, then took a deep breath, and placed it directly.

As a result, after the gladiolus was placed, the second furnace failed again.

The reason is that the medicinal effect of gladiolus is relatively violent, and it needs to be placed into the neutralizing herbs at the same time, but I did not grasp the timing of putting it in, so the other medicinal herbs did not adapt to the fierce medicinal properties of gladiolus, and there was a resistance reaction.

Looking at the eighteen medicinal herbs left, Lei Luo secretly breathed a sigh of relief to himself, and then continued to the next furnace!

The third, fourth, and until the eighth, Lei Luo was fully proficient in the placement time of the medicinal materials, ensuring that there were no problems at this stage of re-discharging the medicine.

The next refining process is naturally more important, not only to ensure that the heat is in place, that is, the problem of fire control, but also to ensure that the fusion of drugs is smooth and cannot make mistakes, so alchemy is really a university question.

In the stage of refining and drug fusion, Lei Luo had problems again, and it was not until around the fifteenth part that Lei Luo entered the final stage of Cheng Dan and Collecting Fire.

The reason why the Sword Heart Pill is difficult to refine is because the sword orchid flower and the sword heart grass contain a trace of sword-shaped aura, and the aura of the sword heart grass can be directly called sword qi, so the refining of the two medicinal materials is particularly difficult.

It is necessary not only to ensure that this trace of aura is not lost during refining, but also to ensure that the refined pill can neutralize the aggressiveness of this aura, so that the sword qi of the Sword Heart Pill can assist the monk to impact the foundation.

This is also the difficult part, but in the twentieth part, Lei Luo kept all the previous nineteen failed experiences in mind, and in the end, there was no mistake.

After all, this pill has been refined in so many copies, and they are already used to it when they place the medicinal materials, and even when they are held in their hands, they know whether there are too many of these medicinal materials, or if the amount is not enough.

Looking at the three white pills lying quietly in the alchemy furnace, Lei Luo, who was now sweating profusely and his face was a little pale, knew that this revised version of the Sword Heart Pill had finally been refined by himself.
