"You know what!"

This old man was none other than Coston-Vanner, the head of the Covenny Academy, a flame quasi-level Holy Spirit level master, and an amateur potions enthusiast. Although Dean Costown has the strength of up to the quasi-level Holy Spirit, his potions talent is terrible!

"In the Tempest Elixir, adding leaves such as Green Flame Leaves can increase the potency and extend the duration of the potion by 40%!"

Dean Costown roared loudly and gave specific figures to prove him right.

"However, the premise is that the high-quality wind potion is above!" Vincent mercilessly pointed to the churning potion in the crystal cup, sniffled, and took two breaths.

"72% purity, not even the excellent level!" Vincent judged the purity of the potion by its smell alone, and immediately shocked Coston.

In addition to the quality of potions, which are divided into rank grades, in the same rank grade, the purity is below 60% according to the purity, which is commonly referred to as defective products; 60% 79% is qualified, 8088% is excellent, 90% is fine, 96% 99% is superb, if the purity is raised to KC%, to the limit, purely composed of potion ingredients, it is absolutely perfect, referred to as perfect!

"Oh, I guess you don't know the consequences, do you?" Vincent continued, "In the 7% purity Tempest Elixir, if you add Green Flame Leaves, you will definitely have a big surprise! ”

"What surprise?" Dean Coston's eyes lit up, "Could it be that you can still improve your purity?" ”

Vincent's brows were dark, if the purity of the potion was so easy to improve, the level of the potion master would not be so difficult to improve.

"You're not going to want to know!"

Dean Costown's eyes showed a look of frenzy, "Of course I want to know!" ”

"Hehe, you don't tell me... I'm experimenting with it myself! Dean Costown placed the Green Flame Leaf in his hand directly into the boiling crystal cup.

Vincent shook his head with a wry smile, enthusiasts are enthusiasts, not professional at all.

The wind potion in the crystal cup churned even more violently, and the green flame leaves quickly dissolved in the potion, quickly dyeing the entire cup of potion into a bright green sè.

"Gollum~~~"

After the potion in the crystal cup turned green, it quickly became viscous and then made a gurgling sound.

Dean Costown didn't notice anything wrong, but leaned closer to watch... He muttered to himself, "Sticky? Is it really to improve purity? ”

Fanny tugged at Vincent's clothes, "Hey, nothing will happen, right?" ”

"Don't worry!" Vincent gave her a reassuring look.

The potion in the crystal cup became more and more viscous, as if a thickener had been added.

"Renfol, come and have a look, I remember you know a little bit about Potions!" Costown seemed to realize that it was too sticky, and called out to Renfour.

Renfort had just stood by Vinson's side, and given Vinson's strength... Renfort was wary of the bright green sè liquid.

He walked over with extreme reluctance, and even released a water-based magic shield.

"Dean, I know what potions, so far I haven't even passed the Potions apprentice exam!"

Coston, however, grabbed him and said, "Do you see if my Tempest Elixir is too viscous?" ”

The potion in the crystal cup, oh no! It should be called a jelly body of green sè ... It's fluttering!

A bad feeling rose in Renfuel's heart, and he quickly strengthened the magic shield.

"Space Barrier!"

The vanishing void emits a gray magic shield that protects Vincent and Fanny.

"Bang Bang Bang~~~"

A series of explosions rang out, and although the explosions were violent, they surprisingly did not have any impact.

The explosion ended, and Vincent removed the space barrier, and Fanny burst into laughter.

"Hahaha~~~"

Wen Du couldn't help but laugh, it was so funny!

Dean Costown is wearing bright green hair at the moment, as if he is wearing a bright green hat!

Renfuer's face was flushed, and his body trembled slightly, obviously he wanted to laugh too, but he didn't dare to laugh.

The explosion just now was entirely due to the fact that the Tempest Elixir of purity 728 was mixed with the Green Flame Leaves, forming a completely new dyeing agent.

And due to the high viscosity of the dyeing agent, as well as the fireworks in the leaves of the green flame, an explosion was suddenly formed.

Dean Costown may have been used to the explosion, and the magic robes on his body were engraved with a defensive magic pattern array, so there was no.

But his head doesn't have any defenses!

Although he covered his face with his arms, there was no protection on the top of his head!

The bright green dye sè dye his head and hair suddenly dyed green and bright!

What a beautiful cuckold!

Costown quickly checked his body and found that he was not injured, and his clothes were not damaged, and he was secretly surprised in his heart, what were these three people laughing at themselves?

"Renfol, what are you laughing at?" Costown was most familiar with Renfull, so he asked first.

Renfull blushed, trying to make a serious expression, but the more he did this, the more weird his expression became!

"Dean, I'm not laughing!"

"Renfol, are you still laughing? Hurry up and say, what are you laughing at! Otherwise, uh-huh! Costown threatened with the dean's shelf.

Renfort shrugged his shoulders and muttered a mantra.

"Water Mirror!"

A mirror made of water appeared in front of Coston, and in the mirror, the head that seemed to emit green light immediately attracted all of Coston's eyes.

"Ahhhh Costown exclaimed.

"Poof!"

"Hahaha~~"

"Ouch hey!"

Vincennes laughed again!

Cosdon involuntarily moved his hands and feet, and found that the person in the mirror also moved his hands and feet at the same time, and that person's face was exactly the same as his, which was clearly himself!

That green and oily head is his own!

"Humph!" Costown slapped the water mirror, his palms blazing.

The water mirror suddenly turned into rising steam and disappeared!

"What's going on?" Costown asked angrily.

Vincent shrugged his shoulders and quipped, "I just said that if I were you, I'd drop the Green Flame Leaves." ”

"Hey, you don't listen to me, it's a tragedy now!"

Coston held back his anger and said, "Is there a way to get rid of these disgusting green sès?" ”

He'd just used magic cleansing, but these pesky green sès weren't affected by magic at all. If he is allowed to be the head of the Coveney Academy and go out with a green head, not to mention the problem of losing face, he will definitely not be spared by the tigress in his family alone!

"Yes, yes, but yes," Vincent said.

"But what? What do you want? Costown asked directly, these little tricks, he still doesn't know after living for more than 70 years?

"I want the Philosopher's Stone!" ―――――！。
