Half an hour later, in the Defence Against the Dark Arts classroom, Professor Link and Keitelburn were standing next to the mutilated body of the Red Hat.

　　 "What a crazy creature!" Professor Keitelburn said with emotion, "Link, what do you think?"

　　 Link didn't speak, but looked at the greedy appearance of the red hat who would lick his own blood even if he died, and finally nodded in agreement.

　　 Outside the classroom, a large group of students are gathering in the corridor and chatting and discussing. From time to time, someone pokes out their heads and takes a look in the classroom. After witnessing the tragedy inside, they shrink back in horror.

　　 Madam Pomfrey and Sprout squatted by the podium, rescuing Lockhart.

　　 The box in the red hat just hit the back of Lockhart's head, and he almost smashed Lockhart's brain directly.

　　 Lockhart would have to become a vegetative if he were to live in the Muggle World, but at Hogwarts, Link reckoned he would be able to recover as long as he lay down for a few days.

　　 While looking at the busy scene of Madam Pomfrey, Professor Keitelburn sighed with emotion:

　　 "Thanks to you this time, Link. Red hats are cruel and flexible by nature, and it is difficult for ordinary wizards to deal with them. If it were not for you, a more serious bleeding accident might happen this time."

　　 "Do you know that ordinary little wizards can't deal with the red hat and lend it to Lockhart?" Professor Keitelburn said with a blank eye, "Don't you know that he is just rubbish?"

　　As soon as Professor Keitelborn’s expression appeared in this statement, he suddenly became a little embarrassed, but he still forcedly explained:

　　 "Of course I know! It's just...but I still didn't expect Lockhart to be **** to the point that he couldn't even deal with the red hat!"

　　 Link shook his head rather speechlessly.

　　 He suddenly realized that Professor Kettleborn might not be as reliable as he seemed.

　　 When Professor Keitelburn saw this, he thought Link was worried about himself, and then slapped Link's shoulder with his big hand and said:

"Hahaha! Don't worry about me, Link. The old man Dumbledore didn't dare to do anything to me. During my tenure, I have been retained for inspection at least 62 times, and now this is nothing at all! Okay! , You’re in a bad state recently, go take a good rest, you won’t use the magical animal protection class in the afternoon, just leave it to me here!"

　　Professor Kettleborn’s tone was very proud, and Link curled his lips and said:

　　 "Then, I will leave first."

　　 After saying this, Link walked out of the classroom.

Ravenclaw and Hufflepuffs along the way saw this and gave way in fear. Only John and a few Hufflepuffs who knew Link well rushed up and excitedly questioned Link’s classroom. Case.

　　The strength that Link showed in the class just now exceeded their cognition, and the final result was really too bloody, which made them unacceptable for a while.

　　 As for other people's attitudes, Link didn't care much, and they continued to walk towards the lounge when they talked and laughed with John.

　　 Before he could go far, he heard Professor Keitelburn’s iconic husky voice again.

　　 "Oh! I almost forgot! Link! You did a great job! Hufflepuff adds 50 points!"

　　……

　　 At night, when the sporadic moonlight was projected into the bedroom through the narrow round windows, Link finally woke up.

　　 Up to now, Link has analyzed and tested most of the materials in the Snape material library.

　　 Link intends to test the remaining materials tonight and complete the development of the invisibility potion in one go.

　　 Thinking so, Link left the dormitory cautiously and walked towards Snape's office.

　　 But when Link came to Snape's office, he was surprised to find that Snape was not fiddling with his cauldron as usual, but stood in front of the workbench and sorted a lot of medicinal materials.

　　 Judging from the pharmacy labels on the packaging of the medicinal materials that have not yet been torn off, these should have been used by Snape to replenish the material library not long after Snape bought them.

　　 This made Link a little guilty, and after greeted Snape in a low voice, he hurried into the material library.

　　 Until the door of the material library was closed heavily, Link was relieved and turned and walked to the temporary workbench he set up in the material library.

　　 The furnishings here have not changed in any way from when I left.

　　 A set of medicine refining equipment, a pile of empty measuring cups, and four samples were sorted out by Link in advance on a workbench that was slightly smaller than Snape's. The only remaining materials have not been tested.

　　If Snape is not playing Link, then the materials that can act as stabilizers should be among the four materials.

　　 Thinking like this, Link rubbed his hands, and even started the experiment.

　　 I saw that Link was very proficient in adding concentrated spider egg liquid and phantom lizard slime to the crucible at a ratio of 6 to 1 for heating, while processing the stabilizer materials to be tested and adding them to the crucible together.

After finishing all this, Link took off his dragon leather gloves and began to write a log about this experiment~lightnovelpub.net~ because now Link only needs to wait for 10 minutes to get it officially. A test sample is out.

　　 And the last test sample Link will be fed to the goblin who is kept in a transparent box next to him.

　　 This kind of little thing that is commonly found in wizards’ back gardens and lives by destroying crops is very similar in body structure to humans, and is often used by potionists as mice.

　　 Link has repeated this process countless times before.

　　 To be honest, this is really boring, even more boring than when Link first started to study the spell in depth.

　　 Fortunately, Link also gained potions experience during this experiment.

For now, relying on the massive supply of resources in Snape's material library, Link has upgraded the material handling and refining operations in potions to LV4. At his current level, he can even go out to Gulin. Those potions workshops in the pavilion are now used as refining operators.

"Ding!"

　　 The alarm clock that Link put next to him made a crisp sound.

On the other hand, Wensheng Link quickly put down the pen and paper, put on the dragon leather gloves, and quickly lifted the lid of the crucible. First, he stirred the crucible three times clockwise with the stirring rod, and then the light gray thick liquid inside was removed. Contained in a beaker.

　　 "Come on, kid, it's time for you to play."

　　 Link said softly and handed the beaker to a goblin.

　　 This greedy creature has very low intelligence and is not resistant to food, so it drank the potion that was still tumbling with bubbles in Link's hand without even a little hesitation.

　　 Then, a magical scene happened.

　　 The goblin who drank all the potion was holding his neck in pain, but its limbs gradually became transparent.
