This change did not arouse much emotional change in Link, he picked up a pocket watch and started timing.

　　Because this was originally a normal reaction after the combination of the phantom lizard slime and the concentrated aspidistra egg liquid, the success of the invisibility potion depends on whether the invisibility effect is stable and lasting.

　　 And Link’s definition of this so-called endurance is 30 minutes. Exceeding or less than this time means that the stabilizer is unqualified.

　　 "Tick tock!~"

　　 The pointer on the pocket watch was beating at a constant speed, and as the pointer got closer and closer to the predetermined time, Link's heartbeat gradually accelerated.

　　 This kind of experience is a bit like CS:GO out of the box, and it's also a bit like DNF opening an epic jar, which makes people feel emotionally excited.

　　 And this emotion finally reached a certain point after the pocket watch finally made a crisp sound representing the end of the countdown.

　　 "Huh!"

　　 Link took a deep breath and looked up into the transparent box.

　　 Then he saw that the goblin in it, which had been completely translucent, was manifesting at an extremely fast speed, returning to its original appearance.

　　 This little guy seems to have not yet reacted to the drastic changes in his body, and is touching him with a shocked look at this moment.

　　 And Link’s expression turned into ecstasy after a short lag!

　　 "YES!"

　　 Link shook his fist vigorously!

　　 The hard work of a week was not in vain after all!

　　 But this is his only celebration.

　　 After the celebration, he quickly suppressed his joy with Occlumency, then turned his head and picked up the quill pen to quickly write on the notebook.

　　 This is the most important task at the moment. Only when the clinical performance of the experimenter is recorded in the test report can a test be considered complete.

After the record was completed, Link tried again with different goblin individuals according to the original formula. He finally poured the last potion into his mouth after he confirmed that the formula was stable enough. .

　　 "Oh!~"

　　The expression on Link's face instantly became exciting.

　　The taste and texture of this potion is like drinking a large glass of citric sour nose, and Link's skin all over his body is extremely itchy after using it.

　　 That feeling, not to mention sour.

　　 But the effect of this potion is also excellent.

　　 Link just drank it, and his body and the clothes on his body quickly began to become transparent, and finally completely transformed Link into an invisible person. Only the slight distortion of light and shadow still proved Link's existence.

　　 Looking at his translucent body, the smile on Link's face finally bloomed uncontrollably.

　　 This kind of joy of success is naturally interesting only if you share it with others.

　　 And the first person Link thought of was Snape.

　　 He cautiously pushed open the door of the material library and walked towards Snape.

At this moment, Snape is still sorting the raw materials on the workbench. This is a very tedious task, because Snape’s requirements for potion raw materials have almost reached the level of BT. The materials sold in the pharmacy must be Pick it again yourself before putting it into your own material library.

　　 As for those who are picked and leftovers are called inferior products, but in fact, the medicinal materials that are of good quality will be put in the classroom by him for the lower grade students to use.

　　 Looking at Snape who was carefully picking out the medicine, Link's movements became more careful.

　　 He didn't want to just run over and say that he was successful.

　　 That is too lack of creativity.

　　In Link's idea, he should have surreptitiously scared Snape while the potion's effect was still there, which was interesting.

　　 But when Link moved slowly behind Snape, he just raised his arm.

　　 A familiar indifferent voice suddenly rang.

　　 "As long as you dare to drop that dirty hand on me, I will really turn into a badger, a flat-headed one! I swear!"

　　 Snape's words made Link's raised arm freeze in the air.

　　 And Snape also turned around at this time, and first looked at Link's with that cold gaze, only showing a distorted silhouette in the air, and then said faintly:

　　 "It looks like you have succeeded."

　　 "Yes, yes! Of course I have succeeded! This is inevitable." Link lowered his arm and said with a little dissatisfaction, "But you are really boring! I originally wanted to surprise you."

　　 "A potionist is a rigorous profession! Surprises are worthless to us!"

"Forget it, isn't the famous Philosopher's Stone and the Elixir of Life created by Nicole Lemay accidentally? This is a great surprise for him, dare you say that this kind of surprise is worthless? ?"

　　 Link relied on being semi-invisible, and Snape couldn't see his expression, so he said with disdain.

　　 But Snape still had a black expression when he heard the words, and said angrily:

　　 "Enough, I don't want to discuss this with you anymore~lightnovelpub.net~ Come on, what do you use as a stabilizer?"

"It's the carapace powder of the color-changing giant snail (Note 1)." Link spread his hand and said, "Actually, poisonous horned beast tails are also possible, but I considered the cost of the drug dosage after delivery, and finally decided to use this plan. Abandoned."

　　 "Heh! You are not too stupid."

　　 Snape's tone was still so cold, but the slight smile at the corner of his mouth had already exposed his mood at the moment.

　　 He was actually quite satisfied with Link's performance.

　　 After all, it is quite difficult to develop the potion by himself, even with the help of Snape.

　　 In terms of creativity and execution, even Snape didn't dare to say that he could be as strong as Link at his age.

　　 But when Snape's eyes caught the pile of materials on the workbench, the smile on his face suddenly solidified.

　　 At the same time, an emotion called heartache came to my heart.

　　 In the past week, Link has almost completely ruined his material library.

　　 It's better to talk about some other common materials. After all, Snape is a potion master, and Jin Jialong is really nothing to him.

　　The key is that some of the materials in the material library are simply out-of-print goods that money cannot buy.

　　 This is a bit bald.

　　 Link, who was not far away, didn't notice the change in Snape's expression, and was still muttering to himself excitedly.

"...Seriously, Professor Snape, you don’t know how difficult it was for me this week. Fortunately, the final invisibility potion was made. But I always find the name invisibility potion a bit too ugly. How about you say I changed its name to Phantom Elixir?"
