As the name suggests, it is a chemical drug that makes people reveal the truth. It was found that after the anesthetic scopolamine is injected into a special state of sedation, the patient will actually answer questions accurately in an unconscious state, or use it to interrogate the prisoner. He called the drug with this effect a drug that has such an effect.

After leaving the real society, the spitting agent generally refers to a high-level potion in the magic world, which is a colorless and tasteless liquid, which also makes the wizards who are unwilling to drink it frightened.

Because after drinking the real spitting agent, you will honestly explain the truth the other party wants to know. This kind of potion is very similar to the magic of God-taking and mind-taking, but the user only needs to prepare a bottle of potion to achieve the goal without having to study such profound magic.

But in general, neither chemical agents in real society nor advanced magic agents in magical world are allowed to be used in formal interrogation because they are all classified as banned drugs.

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

Of course, Pei Chen is not an ordinary wizard, and even he is not even a wizard, so naturally he doesn't have to abide by such wizard laws (...). He spent so much time in Hogwarts Castle, not just to be a role model, but to do nothing else.

In fact, he did his best to collect all the materials he could find - either do it himself, or ask for help secretly, or even ask for advice from the portraits in various classrooms and the ghosts floating back and forth in the castle. In half a semester, he didn't know how many strange things he had accumulated. There were hundreds of bottles and jars of various potions alone, and the spitting agent was only the more precious one.

If he really wants to say that there is something that he is difficult to get, it is probably only a very high-end thing like Fuling Agent, but even if it is an extra-level potion of this level, he still got a small bottle of it-

"Is this the Fuling Agent and the Real Spit?" Hermione looked at the small bottles of potions in Pei Chen's hand curiously, with distrust in her eyes. After all, not everyone would think that this inconspicuous little bottle contained one of the highest-level potions.

Pei Chen stretched out his finger and touched the bottle. 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..."

"Can the Fuling agent really bring good luck?" Hermione said suspiciously. "I have only read it occasionally in books - saying that this thing is the most peculiar little potion, a lucky potion, which will bring good luck to you. Boiling it is very complicated, and if you make it wrong, the consequences will be unimaginable. However, if you cook it, just like in this crucible, you will find that you will succeed no matter what you do - before the effect of the medicine disappears. If you take it overdosed, it will lead to dizziness, recklessness and arrogance."

"I'm right, but unfortunately I can't give Gryffindor points now!" Pei Chen clapped and smiled, his teasing made Hermione's face turn red in an instant.

"To be honest, this thing is not a lucky potion. Its effect can bring luck is just an illusion." Looking at the identification results given by infinite space, Pei Chen explained to Hermione.

"Illusion?" Hermione couldn't believe it, or she couldn't be sure.

"That's right, in fact, it is mainly to improve your abilities in all aspects, such as social ability, magic ability, reaction ability, etc., so that everything will go smoothly." Pei Chen said with a smile, "But the Fuling Agent will probably not play any role in the face of powerful magic. Can you imagine that the scene of defeating the mysterious man with just a bottle of Fuling Agent?"

"It doesn't sound that useful." Hermione was disappointed and rolled her eyes cutely.

"Stop making trouble, this is one of the most difficult potions to refine. How could it be useless? It's just that your expectations for it were too high at the beginning, so I felt disappointed." Pei Chen's eyes turned and a bright red light flashed, "After that, do you know who that old man is?"

"That old man?" Hermione recalled the old man who had traded with Pei Chen before, a very fat bald old man with a pair of convex eyes and a silver beard as thick as a walrus. "I wonder, is he very famous?"

"Haha, Horas Slughorn, a passionate old man... In fact, he was once a professor of potions at Hogwarts Magic School. Yes, he was much older than Snape. If Dumbledore hadn't told me, I wouldn't have known that he actually lived in the village of Badley Barberton." Pei Chen broke the news to Hermione, and quietly diverted Hermione's attention from the fact that he bought banned drugs.

"Potion Class Professor?" Hermione covered her mouth in surprise, "Then why didn't he continue to teach? Is he retired?"

"How could it be? He just saw Voldemort's power at the beginning, so he hid..." Pei Chen said calmly, his tone neither praise nor criticize him. He had no disgust towards the old man, and it was hard to say anything like this.

...

...

Time flies so fast. From the holiday on Christmas Day, it is already the time when the holiday is about to end. In the blink of an eye, it is already the day when school is about to begin.

Pei Chen and Hermione have spent dozens of days of vacation in the true sense - they went to the amusement park to take a roller coaster, watched movies all night in the cinema, ate ice cream and had stomachache, visited various specialty stores and tried their best to shop... and European countries have been wandering around, Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France...

Heidelberg, Didi Lake, Spanish Palace, Sagrada Familia Cathedral, Hofburg Palace, Keukenhof Tulip Garden, Luxembourg, Monaco Church, Cote d'Azur, Leaning Tower of Pisa, Catbai Castle, Montaza Garden, Hagia Sophia Church... Almost as long as it is a famous landscape, they all went there once, and they took photos as a souvenir.

"What's wrong? Are there any more places to go? Anyway, there are still a few days left..."

When taking out the cleaned photos to observe, Pei Chen keenly found that Hermione seemed a little depressed, so he asked.

"No... that, Lyle," Hermione stared straight at Pei Chen, her bright brown eyes made him feel a little panicked, "Are you leaving?"

"...uh, why do you say that?" Pei Chen did not answer positively, but just sighed and asked. He felt that he had been well controlled, and his emotions were not revealed at all, and his words and actions were exactly the same as before. Why could Hermione still see it? Could it be that women's intuitive abilities are really so unreasonable?

This is too unfair to men, right?!

"Ah, sure enough! You are really leaving..." Hermione seemed to have expected it, nodded without answering Pei Chen's question, biting her lower lip and asking, "Are you going back to China? Don't continue teaching?"

"Uh, no. I won't go back to China... and I'm just a substitute professor now, I'm just teaching this school year." Pei Chen thought for a while, feeling that lying seemed to be of no benefit, so he decisively denied the answer.

"So where are you going?" Hermione was slightly surprised. Didn't she go back to China?! She suddenly became anxious and asked.

"...Well, I'm afraid I can't tell you this, but it's definitely not a good place." Pei Chen shook his head with a wry smile and looked at Hermione with a regretful look. To be honest, the other party is really not a good teammate. If you really want to pull her out of this world, you'll be afraid that you will harm others and yourself. Because even if you are the kind of seventh-grade students who can graduate, you're afraid that the star rating in the infinite space will be only one star...

After all, the skill tree point in this magic scene is really strange.

But after all, do I have to consider the choice of my teammate? After all, even the Gunner's sister has started to prepare to form a team, so I can't keep playing stand-alone! If this continues, the creatures outside the box will have opinions! And I also said lonely...

"Then when will you... come back?" Hermione's question broke Pei Chen's random thoughts. He stared at the girl's big brown eyes seriously, pondered the sentences, and finally organized the language-

"This is not very certain...but it may not come back in a short period of time." He sighed silently. This is indeed true. He felt that if he had to die in this mission, he would not have an S-level comprehensive task evaluation. As long as it is not his own exclusive world, it will be difficult to return to that world line after leaving the world line, because the bronze door on the infinite space reincarnation square will automatically refresh every ten standard natural days.

At that time, the bronze door would connect to a brand new world.

If you are lucky, the Apostle of Time and Space may encounter the world you have come to before in the future. However, if you are lucky and have no props that can achieve this effect, you can only bury your memories deep in your heart and wait for time to ferment it into a fine wine... This is undoubtedly a very scammed setting.

...

"Harry?"

Fred looked around in surprise, and George used his body to block the narrow hole exposed by the one-eyed witch statue to make sure no one noticed it. The two teenagers crawled out of the narrow hole one after another.

The red-haired boy who came out first was fine, but his face looked a little ugly. But the black-haired boy who followed him seemed to be out of control, his face was pale as paper, like a ghost, and he staggered when he landed on the ground. If Fred hadn't supported him quickly with his eyes and hands, he would have fallen hard.

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

Fred asked strangely: "You are going to Hogsmeade Village again? Why is this happening? Did Harry meet those dementors?"

"Fred... or George..." Harry looked at the twins' faces, and it took more than a minute to realize that he had returned to the castle. "Don't say anything... don't want anything... please, I want to be alone..."

His expression was blank, and there was a hollow look in his green eyes, and his whole body seemed to be as fragile as it would be shattered at any time. The loneliness and sadness faintly emanated from his body made the twin brothers stop talking, and his extended arms were frozen in the air. He could only watch Harry stumble away, at a loss, and he could not even see the way clearly and could not tell the difference.

The silent and painful boys made them feel a tearing pain.

"Ron, what's wrong?!"
