Lin Yi looked at the scene of smoke billowing inside, his eyebrows furrowed slightly, this feeling of déjà vu made Lin Yi think of such a scene that had happened in Liuxiang Pavilion before.

"How can this have a fight with Miss Ellie, is it Miss Ellie?"

After the smoke in the department gradually dissipated, Lin Yi saw a familiar figure inside, "Isn't that the werewolf clan of the first public class, Tutor Halis, why is he here?"

Looking at Helis choking on smoke in the department, on the desktop in front of it, there were many tools for debugging potions, and Helis saw Lin Yi standing outside the door and said hello.

"Aren't you... Lin Yi of the Elf Clan, is there anything wrong?"

Helis walked outside the door, and at this time, the smoke had all cleared, and he saw countless tools for debugging potions placed inside, "Tutor Halis, are you debugging potions?"

"Oh, are you interested in this too?"

Helis glanced at Lin Yi a few times, "I don't know if Helis Tutor is debugging beginner, intermediate, or advanced?"

Lin Yi saw the many tools placed inside, and thought that it was much more complicated than the last time Aili debugged.

"Come in with me. ”

Helis took Lin Yi into the experimental department, "This time I debugged the intermediate recovery potion, and I tried it all day yesterday, but I still failed." ”

Helis picked up a clear glass bottle on the table, which contained a blue potion. In order to let Lin Yi see the effect of this bottle of intermediate potion, Helis gently cut a wound on his hand with his sharp nails.

The bright red blood flowed out in less than a moment, and then Helis shook the blue potion in the glassware, and slowly poured the potion on the wound he had just opened, when the potion covered the wound, the blood immediately stopped, and at the speed that Lin Yi could see with the naked eye, the wound slowly scarred and then left only a faint scar.

"This is the effect of the intermediate recovery potion, do you see it clearly, Lin Yi of the elf clan. ”

"May I ask Mentor Helis, could it be that the intermediate potion is further blended with multiple primary-level potions to have such a restorative effect?"

After hearing this, Helis shook his head with a smile and said, "The primary potion can still be blended with the extracted plant essence in the same way you said, and the ratios in it must be well matched, not one more point or one point less, you know?"

Lin Yi nodded, the last time Aili was debugging the potion, it was because of the unbalanced proportion that it failed.

"The blending of intermediate potions is not as simple as the beginner, it tests the pharmacist's grasp of the reaction time. ”

"Timing?"

"That's right, the occurrence time of the formula in the intermediate potion determines the success of the potion, and the grasp of this time ......."

Helliston paused for a moment and looked at Lin Yi with a strange expression, "Lin Yi of the Elf Clan, you come and try to mix the three reagent bottles on this desktop first."

Helis pointed to the reagent bottle in front of Lin Yi, Lin Yi didn't know what Helis was for, since it let him give it a try, Lin Yi didn't shirk it, first put the surface dish behind him in front of the table, Lin Yi looked at the three colors of red, yellow and blue, and sensed it a little with magic power, the red potion was the most peaceful, followed by yellow, and finally grumpy blue.

"In that case, let's go red first. ”

Lin Yi picked up the straw next to him and sucked the red potion to the mark he had drawn earlier, Helis saw Lin Yi make a sign on the straw, and instantly understood the truth, "It seems that this kid of the elf clan is not simple." ”

Helis secretly praised in his heart.

Lin Yi dripped the red elixir from the straw into the surface dish, and then used another clean straw to drip the blue elixir on top of the red elixir according to the gourd, and the moment the two touched, a violent reaction immediately occurred.

Fortunately, Lin Yi first used the most peaceful red potion, and after slowly neutralizing the blue potion, he picked up the third straw and covered the yellow potion, only to see that the purple color that had been blended into red and blue tones before was slowly seeped into the yellow potion, and the color slowly and completely transformed into black.

Hellis applauded and looked at Lin Yi with an appreciative expression, "Lin Yi, you really didn't disappoint me, not only did you not disappoint me, but you exceeded my expectations." ”

Helis picked up the marked straw, "How did you come up with this idea?"

"Mentor Helis, since it is the blending of reagents, it is inevitable that the medicine and the medicine are absolutely equal, which is the premise of success. Secondly, it is to use the perception of magic power to see which potion is the most domineering, and which is the most peaceful, which is related to the key to whether the potion and the potion can neutralize each other, I wonder if what the kid said is right?"

"Perfect, even I, as a guru, admire you. ”

Helis picked up the black elixir that Lin Yi had successfully debugged, took out the reagent body in his arms to test the quality of the elixir, and when he put the reagent body on top of the black elixir, when the reagent body turned blue, Helis was surprised, "The quality is excellent!"

Unexpectedly, this Lin Yi used the simplest method to successfully adjust the potion, and the quality was still excellent.

"I have a sentence, I don't know if I can say it?

Helis watched Lin Yi like it more and more, it was the first time he had seen a student who could make him so fond of it, and Lin Yi was the first.

"If there is anything to say, there is nothing that cannot be said between our teachers and students. ”

"Mentor Halis, that kid is straight to the point. Helis nodded.

"Mentor Halis, how long do you think the potion has been stored?"

Helis replied with a smile, "It depends on how you use the storage method, the short is half a year, and the longest is about two years." ”

"Then do you think that with the passage of time, the efficacy of the original high-quality potion can still be maintained at the original level after a long period of storage?"

Helis thought for a while, "I'm afraid this is difficult, after the volatilization of the medicinal properties over time, it is very good to be able to exert half of the medicinal effect." ”

"Does Mentor Helis think there is a need for this so-called potion?"

Helis Huo Ran raised his head and looked at Lin Yi, it didn't know what Lin Yi meant by this sentence, but obviously it could have a hunch that what Lin Yi said next would definitely cause an uproar.

"Mentor Halis, look at this pill. ”

Lin Yi took out a round pill the size of a thumbnail from the ring, "This is Dan... Pills?"

Helis took the pill in Lin Yi's hand, put it in front of his nose and smelled it, and a fragrance that he had never smelled instantly filled the entire nasal cavity, which is not comparable to ordinary medicines 548944127!
