Merlene's hut has been converted into a small laboratory by her...... In fact, it was separated by a cloth curtain, and then an exhaust channel was added, and she was not going to refine any dangerous potions, but she did not need a special laboratory - that kind of laboratory is quite expensive, and ordinary apprentices, unless they specialize in potions and alchemy, generally do not go to the laboratory, and most of these apprentices have the guidance of professional teachers, and it is also convenient to borrow the teacher's laboratory.

In one corner of the hut, there was a handmade shelf of Merlin, on which various materials were stacked in sorts, as well as some improvised monitoring equipment...... For example, temperature and humidity monitoring, crystal balls, etc. No matter what the texture of the material is, it will be different in different environments, even if it is the same material, there will be differences in subtle individuals, and when refining medicine, a little difference in activity will cause different results.

Theoretically, every material is required to remain in the same state forever, but in reality it is completely impossible, and even if they are stored in storage equipment, they will change over time, but the process is slowed down indefinitely.

A qualified pharmacist must grasp the state of the material through contact and observation, and distinguish and adjust it for various subtle changes, so as to ensure the successful refining of the medicine. Therefore, if it happens that a drug has a different material ratio, it is normal not to misjudge.

This only depends on talent, as well as a lot of experience accumulation in the later stage.

Merlin really doesn't have much experience in refining, but the opportunity is for those who are prepared, and she is not even weaker than those advanced wizard apprentices in terms of material preparation and understanding of materials, what she lacks is practice. And in the past six months, she has also accumulated a lot of experience by refining some basic potions, so she has also started a further experimental process - she wants to refine the condensing elixir by herself.

That's right, it's refining by yourself, not scrap purification.

Now she can still get those scrapped potions from the academy's scrap potion warehouse, but when she leaves the academy, what should she do at that time? Taking advantage of the fact that there is a fairly stable environment now, she should seize the time to learn more knowledge and enrich her practice.

After straining through the various precautions in her mind for the last time, Merlin began the first concentrating potion refining.

"Let's go!"

Mei Lin picked up a leaf like a banana leaf with a solemn face, the leaf was very thick, generally blue, but on the leaf, there were some silver stripes, she picked up a blade and cut on one of the silver stripes, and immediately a wisp of silver-blue liquid flowed out.

Blue Silver Grass is the main source of refining the Divine Elixir, and although it is a basic elixir, the price is also quite expensive, so Merlin was very careful and quickly squeezed out all the liquid with a test tube, and then threw the shriveled leaves into the trash.

The silver-blue liquid in the test tube has a thin, pale silver glow floating on the surface, which looks quite hazy and beautiful.

Immediately, Murong Xianxian began to heat the crucible, and while chanting the incantation, she put the other materials that had been prepared into the crucible in proportion, until the impurities inside turned into mist and volatilized, and the night body in the crucible turned milky white, she poured the blue silver grass juice in the test tube, and then stirred it quickly, and at the same time sped up the speed of reciting the incantation......

Burst!

After reading the last set of crucibles, a blue light flashed, and then a foul smell came out, almost making Merlin faint.

"Failed?"

After the foul smell disappeared, Mei Lin looked at the black 'potion' in the crucible with an ugly face, which was also scrapped to the extreme—most of the contemplative potion waste that Mei Lin took out from the warehouse in the past were gray or silver-gray, but this black ...... Tsk, it's the first time I've seen it.

However, Merlin is still acceptable to fail, after all, she is the first time to practice.

Just as she was about to dispose of it, Merlin's heart suddenly moved...... There were already nearly forty silver dots of light in the nebula in her sea of consciousness, so why not try its purification effect?

Do it when you think of it!

Goodo......

When Merlin threw a dot of light into the black liquid, the liquid immediately began to boil...... After about a quarter of an hour, the liquid calmed down, but turned a silvery-gray color.

"In other words, this kind of extremely failed medicine can't even reach the next grade medicine when purified at one time. ”

Merlin frowned slightly, and threw another point of light...... This time, what was harvested was a low-grade potion.

"Although it is a bit overkill, after all, it is a cost saving, and in this regard, there is still a profit. Merlene breathed a sigh of relief.

From the current point of view, the nebula has the effect of aiding meditation, and the light spot has the effect of purification, as for the other functions, it is not too clear now, but Merlin is not in a hurry to explore - the key is to settle the current matter first.

About an hour later.

"Whew!"

Mei Lin was lying on the bed, looking tired, her underwear was already wet with sweat, and the process of refining potions was more powerful than meditation or practicing martial arts. However, the corners of her mouth showed a hint of relief...... Merlin moved her right hand to her eyes and spread out her palm, which contained a silver potion that was emitting a soft glow.

Inferior contemplation elixir!

Although it took only one out of six trials to succeed, it was a huge improvement...... Besides, she has mastered the general rules, and the success rate will be higher and higher in the future. And after those waste products have been purified, they have also become qualified products, and from an economic point of view, she has not lost anything.

However, from a cultivation point of view, the lower-grade condensing elixir was already a little unable to keep up with her use, due to the particularity of the meditation method, she had to use a large number of medium-grade condensing elixirs, especially the impact second-level apprentice was imminent.

What to do?

Mei Lin lay on the bed and began to think, and after a moment of silence, she clapped her palms and decided to purify the existing low-grade concentrating elixir into a medium-grade elixir, which would not only ensure her promotion, but also be able to use it for a period of time after she went out.

Of course, the long-term solution is to refine the potion by yourself, although it will take more time, but people do things, the vision should be a little longer-term, the so-called practice makes perfect, when I first started refining the physical potion, the success rate was not very low, and the steps were difficult, but what happened later, now it is very casual.

Happy Holidays, Kiss the Women!!
