Black vinegar onion is a special plant that has only been cultivated artificially in recent decades.

　　The smell of this special plant is very irritating, and it is often used in some dishes and special potions.

　　 But also because of their special taste, the process of Link peeling them became extremely irritating.

　　 It can be said that Link also fully felt what is called "the sour smell of love".

　　 Fortunately, Snape was still somewhat conscientious and didn't embarrass Link too much. This so-called ‘herbal treatment exercise’ was only halfway through, and Snape let off Link.

　　 "Huh! Huh!"

　　 took off the dragon leather gloves, Link was constantly washing his eyes with clean water, and at this moment, they had been irritated and completely turned red.

　　 And Snape smiled impenetrably when he saw it, and sat back on his favorite chair and said:

　　 "Do you have any direction regarding the development of that invisible potion?"

　　 Link's movements paused, and he knew that the key point had arrived.

　　 "I plan to use concentrated spider egg liquid (Note 1) to increase the effect of the phantom lizard slime. If the ratio is adjusted, it should be able to enhance the effect of the phantom lizard slime to the level that can be used."

"Concentrated aspidistra liquid?" Hearing that the smile on Snape's face became thicker, "Concentrated aspidistral liquid, as an auxiliary material that can enhance the effect of other potions, is indeed very effective. . But its effect is not stable. If you use it forcefully, the yield of the potion will be terribly low. So... you also need other things as a stabilizer to neutralize both of them."

　　 Link nodded thoughtfully.

　　 After studying potions for more than a year, Link, who already had a certain foundation of potion knowledge, naturally knew that Snape didn't panic.

　　 His original idea was indeed lacking.

　　 But if a stabilizer is to be used, what substance should be used?

　　 Link's mind flashed the names of countless kinds of herbs, but he still couldn't confirm which one was the most suitable choice.

　　 After hesitating for a while, Link finally looked at Snape.

　　 He was going to try Snape to see if the other party could give some hints.

　　 "Professor Snape, if it were you, what would you choose to use as a stabilizer?"

　　 Link's tone was extremely sincere, with a hint of respect, which made Snape very comfortable to hear, and the smile on his face also tended to develop toward a larger arc.

　　 But he didn't want Link to succeed.

　　 saw him smile and shook his head and said:

　　 "It's up to you to experiment with this. If I tell you everything, can this still be considered a potion you developed?"

　　 The respectful look on Link's face disappeared in an instant.

　　 He gave Snape a blank look, then turned his head and walked into Snape's material warehouse, began to select materials, and tried to mix stabilizers.

　　 Link knew very well, with Snape's character, since he said he wanted to try it by himself, he would never give any more hints.

　　 Then instead of continuing to grind on his side, it is better to start the experiment earlier. Anyway, looking at Snape's appearance, the stabilizer material will not be so rare that it can't be obtained.

　　 Link felt that as long as he kept experimenting in Snape's material library, he would eventually be able to find that substance.

　　 Of course, by the way, Link is also planning to waste more Snape's materials. It is best to empty his material library!

　　 to repay Snape's petty vengeance!

　　 At this time, Snape obviously didn't know Link's plan. He smiled very rarely when he saw it, and then returned to the cauldron even if he was in a good mood, ready to continue his previous refining medicine.

　　 But as soon as he sat down, he saw Emily's resentful face.

　　 This made the smile on his face disappear in an instant.

　　 As a witness to the summer dinner at the Victoria Mansion, he naturally knew why Emily was angry.

　　 "Uh... Emily..."

　　 Snape said intermittently, but he couldn't say anything to comfort people.

　　 From his birth until now, Snape has not been the kind of person who is good at coaxing girls.

　　 This makes him look a little overwhelmed.

　　 Fortunately, Emily obviously didn't want to hear anything good from Snape.

　　 She snorted coldly at Snape, and then rushed into the material library with Link.

　　 While looking at the two figures leaning together in the material library, Snape couldn't help but fall on the black vinegar onion that Link just peeled off in the corner.

　　 He felt that Link's onion must have not been peeled clean just now.

　　 Otherwise, why is there a sour smell in this room?

　　……

　　 A week later, Link was finally freed from the massive material experiment.

　　 It's just that it wasn't because he finally found a material that could act as a stabilizer, but Snape forcibly gave him a vacation.

　　 This is reasonable.

　　 Because in the past week, Link has put almost all of his rest time in the material library.

　　 Drink nutrients when you are hungry, drink refreshing drugs when you are sleepy, and do experiments day and night.

　　 Such high-intensity work made Link pale as a vampire, and his whole spirit became very sluggish~lightnovelpub.net~ Such seriousness made Snape a little moved.

　　 But Snape grabbed Link by the neck and poured him a bottle of life and death water, and threw him out of the office after Link had slept for ten hours.

　　 "Hey!"

　　 Looking at the reclosed arched stone door, Link smacked his mouth in dissatisfaction.

　　 He has tested most of the materials in Snape's material library in the past week. He has a hunch that he will succeed soon.

　　 It turned out to be thrown out.

　　 This made Link wonder if Snape was distressed because he used too much material.

　　 After all, the raw material reserves in Snape's material library have now been shrunk by more than half by Link.

　　 And when he thought of this, the dissatisfaction on Link's face instantly turned into a snicker, and at the same time his hand was put on the pocket of the non-marking stretch curse on his waist.

　　 What Snape didn't know was that nearly half of the potion materials in his material library were actually in Link's own pocket.

　　 This wave!

　　 Link earns a lot of money directly!

　　 rubbed the non-mark stretch curse pocket, felt the bulging feeling inside, and Link flew towards the auditorium.

　　 Link is not in a hurry to make the invisible potion now.

　　 Anyway, Snape gave him a twelve-hour holiday, and he would come back by himself.

　　 As soon as Link arrived in the auditorium, he ran into John who was about to come out of it.

　　 Although it was early morning, John was wearing a full set of Quidditch protective gear, and his face was sweaty.

　　 This is nothing.

　　 What really makes Link feel strange is that John's mood is extremely low at the moment, as if he has encountered some catastrophe.
