Merlin deduced that the dead wizard was most likely killed because of that treasure, and for herself, don't be too curious, be yourself, keep a low profile, and then use those two high-quality condensing potions to break through.

As for the purpose of that nebula and the point of light, it can only be analyzed slowly...... She had read some of the free books in the academy, and there seemed to be nothing that could explain the origin of the nebula-like mist, and as for asking others, it was simply self-defeating, and the wizards in the academy were all sharks, and when the time came, they could swallow Merlin to the point that there would be no skin and bones left.

In order to avoid being discovered, Merlin sewed the storage bag into the pocket of her clothes, although it was a little more troublesome to take things, but it was better than putting it in the house, and as long as it was not discovered by others.

I don't know if it's the effect of feeling, Mei Lin feels that she has entered a meditative state very quickly in the past few days, and after meditating before, she was very tired, but now she meditates more than twice as long as before, and she is just a little tired. What surprised her the most was that there was an extra one of those points of light in the nebula...... She was a little surprised, it seemed that the nebula was the one who gave birth to these points of light.

There are three effects of a treasure: attack, defense, support, and waste.

First of all, the 'waste' option was crossed out. , these nebulae are definitely not waste.

Secondly, Mei Lin has experimented with sword slashing, stone smashing, fire and other methods, although those points of light will not dissipate, but they also have no defense at all, so the defense attribute is also zero.

Finally, there is the secondary effect. This point seems to be significant, for two weeks in a row, Mei Lin's single cultivation time has been greatly extended, and after the end, there is no obvious feeling of fatigue...... Not only that, Mei Lin also felt that her physique seemed to have improved implicitly, and some skills that could not be used before could now be easily displayed, and her strength had also improved.

"Maybe we should dig into what it's used for. Merlin muttered to herself in the room.

Since these points of light cannot be dissipated with fire, the water ...... Will it melt with a corrosive potion?

These points of light have reached twelve, and at this rate, the nebula will be able to give birth to one point of light on its own every week, and even if it is wasted, it is not unacceptable.

Thinking of this, Merlin immediately took action...... One of her harvests was a corrosive potion, but Merlin was reluctant to use it for testing. Fortunately, she works in the medicine garden, and it is not difficult to get some herbs, plus some other materials, and a corrosive agent will come out...... Of course, the water content of this potion is too large, and compared to a real magic potion, it is not comparable at all, at best it is called a corrosive potion.

Mei Lin was a little hesitant when she used her telekinesis to call up a point of light from the sea of knowledge...... She had experimented that no matter where she 'throws' the point of light, if she doesn't control it with her mental power for a long time, it will automatically return to the sea of consciousness. If this time it is still undamaged, and the light spots contaminated with the corrosive potion return to Zhihai, there will be no sequelae, right?

"If you don't enter the tiger's den, you can get the tiger!"

After thinking about it again and again, Merlin gritted her teeth and manipulated the light spot that fell into the potion in the test tube.

'Goodo......

As soon as the light spot entered the pale green liquid in the test tube, the originally calm liquid suddenly tumbled like a pot, and a pungent smell suddenly rushed out of the test tube.

The surprise startled Merlin, who jumped backwards and hurriedly took out a spell scroll...... It was the only defensive scroll in the harvest that sealed a 'Mage Armor' spell that she didn't want to use unless she had to.

Fortunately, although the liquid in that tube was boiling and there was a gas spill, there was no further threat...... After about a quarter of an hour, the sound died down and the liquid returned to calm, and although the room was filled with a pungent smell, the threat was not great.

"It smells like corrosive agents. Merlin frowned slightly, hesitating to take a closer look.

The Corrosive Potion was actually made from the Corrosion Potion, as Merlin was not yet an official apprentice and could not refine the potion, but the potion recipe was something she remembered when she helped other wizards prepare the materials for the alchemy...... Of course, the wizards didn't expect their prescriptions to be memorized by an informal apprentice, thanks entirely to Merlene's strong memory.

After a long pause, the pungent smell in the air had gradually dissipated, and Merlin came to the table with the spell scroll in her hand...... The spot of light didn't fly out, and the color of the liquid in the tube had changed from pale green to dark green—the color of the real corrosive agent.

"Hell, could it be that the purpose of these light spots is to refine medicine instead of the pharmacist?" Merlin looked at the liquid in the test tube, and couldn't help but be full of surprise.

If it is only the effect of refining the elixir...... To be honest, this support is good, but it is much lower than Merlin's expectations. And in terms of quality, this corrosive agent has reached the next grade, and it can be regarded as a real use.

After thinking for a moment, Merlin suddenly had an idea...... If these light spots can synthesize some raw materials into real chemicals, will it have an impact on those end-of-life chemicals?

Thinking of this, Merlin excitedly dragged out a cloth bag from under the bed...... The old guy in charge of distributing benefits took sixteen scrap potions in order to anger her, but fortunately, he studied the nebula and the light spot during this time, and he didn't bother to throw it away.

When one of the discarded potions was opened, the contents of the test tube were pale gray...... Generally speaking, magic potions can be divided into low-grade, medium-grade, top-grade, and super-grade according to their quality. As for the effect, of course, the higher the grade, the better the effect.

In terms of concentrating elixirs, the lower grade is silver, the middle grade is highly silver, the upper grade is like mercury, and the surface of the best elixir is full of luminous light, which seems to have a bit of texture.

In the nebula in the sea of Merlin's knowledge, there were only eleven bright spots left, so she controlled it with her telekinesis and moved out another one...... If someone knows about her action at this time, not to mention whether they will covet that nebula, they will also give a thumbs up and praise the word 'cow' for this kung fu.

Carving the will rune in the sea of consciousness can actually be said to be a kind of use of spiritual power. But what Merlin didn't know was that she did some very outrageous actions in order to figure out the role of the nebula in the sea...... That is, her mental power is strong, and the effect of Nebula is weird, so she didn't make any other trouble, and it wasn't until a later battle that she realized that she had unknowingly mastered a unique method of using spiritual power.

The point of light entered the potion under her control, although Mei Lin had been prepared, but when the potion boiled, she still subconsciously tilted her head back...... 'Goo', the potion churned more and more violently, but the gray inside was getting lighter and lighter.

"Miracle ......"

Merlin, who had been staring at the changes in the potion, was stunned by the real phenomenon in front of her.
