Chapter 685: Tactical Potion and the Half-Blood Prince's Potion Textbook

In the afternoon, Irina, Harry and others came to the underground classroom of the advanced potion class.

Unlike the Defense Against the Dark Arts class, not many young wizards get high scores in the O.W.L. exam in potions. There are only more than 20 young wizards from the four colleges who meet the standards and can participate in the advanced potion class.

Among them, there are four Slytherin wizards, nine Ravenclaw wizards, three Hufflepuff wizards and twelve Gryffindor wizards.

Even so, the number of people participating in the advanced potion class has more than doubled compared to the original book.

In view of the small number of people participating in the advanced potion class, the young wizards from the four colleges were merged into one class and took classes together.

In Irina's opinion, Professor Snape is somewhat responsible for the low pass rate of the potion class.

Even though Professor Snape is serious and responsible, Irina disagrees with his teaching method.

Strictness is a good thing, but forcing students to be stressed and treating stress as a freak is a bit too much.

After all the young wizards who participated in the advanced class arrived, the door of the underground classroom opened. Slughorn had not yet appeared, but his big belly had already come out.

Everyone walked into the classroom in an orderly manner. Slughorn smiled and greeted everyone. His walrus beard trembled on his smiling mouth. He greeted Irina, Harry and others with great enthusiasm.

Especially when greeting Irina, his eyes revealed a bit of enthusiasm as if he was looking at a treasure, and a bit of awe for the demon king-level wizard.

Unlike the lifeless dungeon-like classroom in previous years, the underground classroom at this time was filled with steam and various strange smells.

Everyone walked past a row of crucibles, sniffing the smell of the potion in the crucible. Irina, Harry, Ron and Hermione chose a table closest to a golden crucible, which exuded a burst of fragrance.

Draco, who was walking behind the team, hesitated for a moment and chose a table not far from the golden cauldron to sit down.

The smell of the potion spread as the steam spiraled up, intoxicating Harry immediately.

Harry had never smelled such a tempting smell before. It reminded him of honey pie, the smell of the wood of a flying broom, and the scent of flowers that he must have smelled at the Burrow.

Unconsciously, Harry found himself breathing in slowly and deeply. The smell of the potion filled his body like alcohol, and a huge sense of satisfaction slowly came to him.

If the Harry sitting here was still the same Harry as before, perhaps he would have been addicted to it and could not extricate himself.

But don't forget that the Harry now is Harry who has been tested by countless illusions!

"Love potion..."

Harry subconsciously operated the brain block technique to make himself clear again, and he murmured softly.

Irina, who was sitting next to Hermione, gently stretched out her fingers, hooked a wisp of white smoke, and felt the smell of the steaming mist love potion.

The warmth of a flame, the stimulating but not offensive smell of burning, and... a slight sweetness...

That sweetness...

Irina thought, she recalled the two close touches, and her pretty face blushed.

Everyone sitting around the golden crucible smelled their favorite smell from the faint mist of love potion.

"Okay, okay," Slughorn finally spoke, and his big body seemed to be floating through the hot steam, "Classmates, please take out your scales, medicine bags, and don't forget to take out your "Advanced Potion Making" textbook..."

Just when Slughorn was about to start his class, Harry raised his hand.

According to Professor Snape's original requirements, Harry and Ron's O.W.L. test scores were not enough for them to take the advanced class, so Harry and Ron did not prepare the textbooks for potions in advance.

After learning about Harry and Ron's situation, Slughorn strode to a storage cabinet in the corner.

He fumbled around for a while, took out two tattered copies of "Advanced Potion Making" by Libasho Pollach and two sets of dim and faded scales, and handed them to Harry and Ron.

Harry and Ron returned to their seats with the old books and old scales in their hands.

Irina leaned over her head, and after she saw the old book in Harry's hand and the words "This book belongs to the Half-Blood Prince" written on the back cover, she showed a barely perceptible smile on her face.

As early as when Lynn had thoroughly understood the notes in the book and shared them all with her, they erased the Sharp Spell recorded in the book and put it back to its original position.

The reason why Lynn and Irina wanted to erase the Sharp Spell recorded in the book was that they had already taught this spell to members of the D.A. Army, and erasing it would not arouse Harry's suspicion.

Secondly, because this spell is really too dangerous, Lin En and Irina don't want other young wizards to learn the Divine Edge Spell after getting this book and then use it everywhere.

After all, those young wizards are not members of the D.A. Army and have not received their warning in advance.

Moreover, no one knows how many years it will take for this old book to fall into the hands of others.

After taking the old books for Harry and Ron, Slughorn returned to the front of the classroom. He pushed his already bulging chest forward again, and the buttons on his vest were about to burst off.

Slughorn said loudly: "I have prepared several potions for you to open your eyes. Of course, it's just for fun. When you finish the advanced course, you should be able to make something like this. Although you haven't made it yourself, you must have heard of it. Who can tell me what this one is?"

Slughorn pointed to the row of crucibles in the front.

The potions in these crucibles are truth serum, polyjuice potion, love potion, and felicity potion, which is called the lucky potion.

Hearing Slughorn's question, all the young wizards of the D.A. Army raised their hands.

Although they didn't know how to brew these potions yet, they had to deal with them in the tasks of the illusion test.

Whether it was the truth serum used to interrogate the enemy, the polyjuice potion used for disguise and infiltration, or the love potion used to subvert, control, and use the enemy, they were all tactical potions that they used frequently in the illusion test.

Yes, the young wizards of the D.A. Army collectively referred to all potions that could be used in combat or various actions as tactical potions.
