Truth-telling, as the name suggests, is a chemical that makes people tell the truth, and it is the American obstetrician-gynecologist Robert House's discovery that after injecting the anesthetic scopolamine, the patient enters a special state of sedation, and will answer questions accurately in an unconscious state, perhaps to interrogate prisoners, he calls drugs with such effects as truth-telling.

Separated from the real world, the elixir generally refers to a high-level potion in the wizarding world, which is a colorless, tasteless liquid, which also frightens wizards who are reluctant to drink it.

Because after drinking the elixir, you will honestly confess the truth that the other person wants to know. The effect of this potion is very similar to that of the Dementor Magic, but the user only needs to prepare a bottle of potion to achieve the goal, and does not need to delve into such advanced magic.

However, in general, neither the real-world chemicals nor the high-level potions in the wizarding world are allowed to be used in formal trials, as they are classified as banned drugs.

Even ordinary wizards were not allowed to carry such medicines at all.

Of course, Pei Chen is not an ordinary wizard, and he is not even a wizard, so naturally there is no need to obey such wizard laws (...... ）。 He spent so much time at Hogwarts Castle not just to be a role model, but to do nothing else.

In fact, he did everything he could to gather all the materials he could find—either by himself, or by secretly asking for help, or even by asking for advice from the portraits in the classrooms and the ghosts that wandered around the castle. After half a semester, he didn't know how many strange things he had accumulated. There are hundreds of bottles and jars of various potions alone, and among them, the truth elixir is only the more precious kind.

If there is anything that is difficult for him to get his hands on, it is estimated that there is only a particularly high-grade thing like the elixir, but Rao is this level of extra-spec potion is still a small bottle he still got -

"This is the elixir of blessing and the elixir of truth?" Hermione looked curiously at the small bottles of potions in Pei Chen's hand, her eyes were full of distrust, after all, not everyone would think that this inconspicuous little bottle contained one of the highest level potions.

Pei Chen stretched out his finger to touch the bottle, and after confirming the identification information of the infinite space again, he nodded, "That's right, it's this thing, although it doesn't look very eye-catching......"

"Elixir really brings good luck?" Hermione said skeptically, "I've only read it occasionally in books - that this thing is the most peculiar little potion of all, a potion of luck that will bring you good luck." It's very complicated to boil, and if you get it wrong, the consequences are unimaginable. However, if you boil it properly, like the one in this cauldron, you will find that you will succeed in whatever you do - before the effect wears off. If taken in excess, it can lead to vertigo, recklessness, and hubris. ”

"That's right, but unfortunately I can't add points to Gryffindor right now!" Pei Chen clapped and laughed, and his ridicule made Hermione's face flush in an instant.

"To be honest, this thing isn't actually a luck potion, and its effect is just an illusion that it can bring luck." Looking at the appraisal results given by the infinite space, Pei Chen explained to Hermione.

"Delusion?" Hermione couldn't believe it, or rather, she wasn't sure.

"That's right, in fact, the main thing is to improve all aspects of your abilities, such as social skills, magic skills, reaction skills, etc., so that people will feel that everything is going well." Pei Chen smiled and said, "But the elixir is estimated to have little effect in the face of powerful magic, can you imagine the scene where you can defeat the mysterious person as long as you have a bottle of elixir?" ”

"Something that doesn't sound that useful." Hermione was stunned and rolled her eyes cutely.

"Don't make a fuss, this is one of the most difficult potions to refine, how can it be useless? It's just that your expectations for it are too high at first, so you feel disappointed. Pei Chen's eyes rolled, and a bright red light flashed, "Then again, do you know who that old man is?" ”

"The old man?" Hermione remembered the old man she had traded with Pei Chen, a bald old man who was incredibly fat, with bulging eyes and a silver beard as thick as a walrus. "I don't know, is he famous?"

"Haha, Horace Slughorn, a passionate old man...... In fact, he used to be a Potions professor at Hogwarts School of Witchcraft and Wizardry, yes, much older than Snape, and I wouldn't have known he lived in Badley Barberton Village if Dumbledore hadn't told me. Pei Chen broke the news to Hermione, and quietly diverted Hermione's attention from the fact that she was buying illegal drugs.

"Potions Professor?!" Hermione covered her mouth in surprise, "Then why doesn't he continue to teach, is he retired?" ”

"How so? He just saw that Voldemort's power was great, so he hid......" Pei Chen said calmly, his tone was neither praise nor disparagement, he didn't have any ill feelings towards that old man, and it was not easy to say anything about this kind of thing.

……

……

Time flies, starting from the Christmas holiday, this is already the end of the holiday, and in the blink of an eye, it is already the day when school is about to start.

And Pei Chen and Hermione spent dozens of days of vacation in the real sense - going to the amusement park to ride a roller coaster, watching an all-night movie at the cinema, eating ice cream until their stomachs hurt, visiting various specialty stores and desperately sweeping the goods...... And all the countries of Europe have gone around, Austria, Belgium, Cyprus, the Czech Republic, Denmark, Estonia, Finland, France, ......

Heidelberg, Didi Lake, Royal Palace of Spain, Sagrada Familia, Hofburg Palace, Keukenhof Tulip Gardens, Luxembourg, Monaco Church, Côte d'Azur, Leaning Tower of Pisa, Caterpillar Castle, Montaza Gardens, Hagia Sophia, ...... Almost as long as it is a famous landscape, they all go once, and they all take pictures.

"What's wrong? Is there anything else you want to go? Anyway, there are still a few days to go......"

When he took out the cleaned photos to observe, Pei Chen keenly noticed that Hermione seemed to be a little sullen, so he asked.

"It's not...... That, Lyle," Hermione stared straight at Pei Chen, her big bright brown eyes making him a little flustered, "Are you leaving?" ”

“…… Uh, why do you say that? Pei Chen didn't answer positively, just sighed and asked, he felt that he had controlled it very well, not the slightest emotion was revealed, and he spoke and acted exactly the same as before, why could Hermione still be able to see it? Is it really that women's intuitive abilities are so unreasonable?

That's too unfair for men, isn't it?!

"Ah, sure enough! You're really leaving......" Hermione seemed to have expected it, nodded and didn't answer Pei Chen's question, biting her lower lip and asking, "Are you going back to China?" Don't continue to teach? ”

"Well, no. ...... will not return to China And I'm a substitute professor now, and I'm just teaching for the school year. Pei Chen thought about it for a while, and felt that it seemed that it was no good to lie, so he decisively denied this answer.

"So where are you going?" Hermione was slightly stunned, didn't she go back to China?! She immediately became anxious and asked.

“…… Well, I'm afraid I can't tell you this, but it's definitely not a good place to be. Pei Chen shook his head with a wry smile, and looked at Hermione with a regretful gaze, to be honest, the other party is really not a good candidate for teammate, if he really wants to pull her out of this world, he is afraid that it will harm others and himself. Because even if it's the kind that a seventh-grader can graduate, I'm afraid that the star rating in the infinite space is only one star......

After all, the skill tree of this magical scene is really weird.

But then again, do you have to think about the selection of your teammates? After all, even the gunman's sister has already begun to prepare to form a team, so it's hard to be alone all the time! If this continues, the creatures outside the box will have an opinion! And I blamed myself for being lonely......

"What about you...... When will I be back? Hermione's question broke Pei Chen's thoughts, he stared at the girl's big brown eyes seriously, considered the sentence for a while, and finally organized the language-

"Well, I'm not too sure...... However, it may not come back in a short time. He sighed silently, this was indeed the truth, he felt that he would not be able to have an S-level comprehensive mission evaluation if he died in this mission. And as long as it is not your own exclusive world, it is difficult to return to that world line after leaving the world line, because the bronze door on the reincarnation square of infinite space will be automatically refreshed every ten standard natural days.

At that time, a whole new world would be connected behind the bronze door.

If you're lucky, the Apostle of Time and Space may be able to encounter the world that has come back in the future, but if you're unlucky, you don't have the props on hand that can exert this effect, so you can really only bury your memories deep in your heart and wait for time to ferment them into fine wine...... This is undoubtedly a very cheating setting.

……

……

"Harry?"

Fred looked around in surprise as George blocked the narrow hole revealed by the one-eyed witch statue to make sure no one noticed. Two teenagers crawled out of the narrow hole one after another.

The red-haired boy who came out first was fine, but his face was a little ugly. But the black-haired boy who followed him seemed to be in a state of despair, his face was as pale as paper, like a ghost, and he staggered when he landed, and if it weren't for Fred's quick hand to hold him, he was afraid that he would have to fall firmly.

"Harry......" Ron looked at Harry, his lips moving slightly.

Fred asked curiously, "Are you going to Hogsmeade again?" Why is this the case? Did Harry meet the Dementors? ”

Fred ...... Or maybe it's George......" Harry looked at the twins' faces, and it took more than a minute for him to realize that he was back in the castle. "Don't say anything...... Nothing...... Please, I want to be alone ......"

His expression was blank, his green eyes were empty, and his whole person seemed to be fragile as if he would shatter at any moment. The loneliness and sadness that emanated from his body made the twin brothers stop talking, and their outstretched arms were frozen in mid-air, and they could only watch Harry stumble away, as if he couldn't even see the road clearly.

The silent and painful teenager made them all feel a tearing pain.

"Ron, what's going on?!"

Ron was full of excitement, and when he came back to his senses, he bit his dry lip and forced a smile: "That...... Harry and I just went to the Three Broomsticks Bar and ran into Professor McGonagall, Hagrid, and Minister Fudge......"
