Tang Bai's figure reappeared in the subway station in the present world. The Harry Potter World team, although it did not achieve his original purpose, provided him with a better choice.

A potion shop of a small scale is far more valuable than piles of finished potions and the medicinal materials used to make potions in the long run.

Not to mention anything else, just talking about the many excellent potions makers in the potion shop is a rare asset. Not to mention that with the connections and energy that Mellen Watts has accumulated over the years, Tang Bai can also obtain some precious, but forbidden to trade and trade, and can be called contraband.

In addition to having one more industry in the Harry Potter world, Tang Bai did not return empty-handed this time. Although Mellen Watts's potion shop business has long been much worse than before, it can even be said that it is surviving. However, there is still a large inventory of finished potions, as well as potions and medicinal materials.

When Mellen Watts sold the potion shop, the value of these stocks was naturally taken into account. In other words, these backlogged stocks, together with the potion shop, can be regarded as Tang Bai's personal belongings. If it weren't for the fact that this was the dark period when Voldemort was in power, the inventory in the potion shop alone would have been worth half of the gold galleons that Tang Bai had paid.

In the mirror world where the mirror spirit is located now, there are a batch of potions and potions medicinal materials brought back by Tang Bai, as well as a complete set of potions books. Compared to the huge inventory of the potion shop, the amount of potions and other potions that Tang Bai brought back could only be said to be a fraction of the amount.

The conversation with Mellen Watts also made Tang Bai understand how unreliable his big purchase plan was at the beginning.

Potions have the same expiration date as all kinds of potions in the present world, but after the potions are made, they can not be stored safely within the expiration date like the ones in the present world. The processing and storage of potions, as well as the production and maintenance of potions, are extremely demanding in terms of manual maintenance processes and environments. Failure or failure in any of these processes will affect the final effect of the potion, as well as the expiration date.

Many high-grade potions are made with extreme demands on the freshness of potions, so potions shops like the Mellenwood Potion Shop will have their own dedicated space for growing potions, as well as the manpower to grow and maintain them.

If Tang Bai really bought piles of finished potions and potions and medicinal materials back to the present world as originally planned, I am afraid that the purchased potions and medicinal materials can finally be used for one-tenth of the amount, which is already good.

When he returned to his rental house, he opened the door and went in, and before he could close it, Jing Ling's words immediately made him frown.

"There's someone in your room."

"It's Fengzi?" Tang Bai subconsciously asked in his heart. In his impression, the only person who can enter without telling seems to be Qi Lianfeng, who also has the door key in his hand.

"It's a woman," Mirror Spirit's reply quickly rang out, "with a knife in her hand." ”

When Tang Bai heard this, his heart suddenly tightened, and then he was relieved. Under the ability of the mirror spirit, a simple knife could not pose any decent threat to Tang Bai at all, so Tang Bai did not worry about his own safety for the time being.

Tang Bai's rental house has a very poor sound insulation, so the sound of Tang Bai's door opening just now must have alarmed the other party. If you are an ordinary person, the practice of insurance is naturally to withdraw again, and then decisively attract a few of your own friends.

But Tang Bai doesn't need to be like this. He turned and closed the door, locked it with his backhand, and walked straight to his room. Put your hand on the handle of the house and push the door in.

A snow-bright blade in the darkness was across Tang Bai's neck in an instant. Tang Bai, who had already anticipated and guarded against this scene in advance, did not show any nervous and panicked look on his face.

"Please don't act rashly." A pleasant female voice suddenly sounded in the darkness, and her tone was a little peculiar.

"Who are you?" Tang Bai followed the blade and looked at the woman who spoke in the dark, his face a little gloomy. Even if you anticipate it in advance, even if you know that the other party can't hurt you, just like no one wants to be pointed at the muzzle of a gun, whoever is pointed at by a sharp blade will not feel too comfortable in their hearts.

While Tang Bai was angry in his heart, he was also a little suspicious of the other party's origin. Although the Mirror Spirit's abilities are powerful, they have the same obvious regional restriction and restriction surnames.

The lights flickered.

The uninvited guests in Tang Bai's house were exposed to the pouring lights at the same time as him. Tang Bai also took the opportunity to see clearly the person holding the blade pointing at him.

Dressed in a black tight-fitting suit, clinging to his tall figure, with short black hair and a picturesque face. The woman looked extremely young, about twenty-one or two years old. What is sighing is that a delicate face is beautiful, but the face is like an expressionless human skin mask, which brings people a sense of alienation and coldness. If it weren't for the chilling wisps of evil revealed by the corners of his eyebrows and eyes, Tang Bai would have thought that the other party was like a porcelain doll without emotion.

The other party ignored Tang Bai's question, and as soon as the blade of the knife in his hand turned around like a foot long, his body instantly approached Tang Bai, and then the inverted hilt hit Tang Bai's head fiercely. This blow was really swift and swift. Don't say that Tang Bai has no intention of dodging, even if he wants to dodge, with the gap between him and the other party, I am afraid that he is powerless.

The woman's body collapsed to the ground limply, and Cheng Liang's knife fell to the ground with the owner holding it. The other party's actions were obviously to knock Tang Bai unconscious before acting, but unfortunately, she didn't know Tang Bai's ability. This level of attack would hardly cause any damage to Tang Bai, who had the Mirror Spirit.

"What are you going to do?" Looking at the woman in black who had fainted to the ground because of the effect of the mirror, the mirror spirit who had already walked to the wall mirror asked curiously.

"Intelligence and intentions." Tang Bai's answer was concise and to the point. Silently, he lifted the woman on the ground and clipped it under his waist. The other party's weight of less than fifty kilograms is almost as light as nothing for Tang Bai, whose physical fitness has increased greatly now.

Although the other party did not threaten Tang Bai's life, he was pointed at with a knife, which was obviously not a good sign. If he didn't understand the other party's intentions, there was an ownerless messenger behind the scenes, and Tang Bai was afraid that he would not be able to sleep peacefully in the future. As for whether the other party would say everything willingly, Tang Bai didn't care.

He doesn't know how to use torture, and he doesn't know what torture techniques he has, but with the various means he has in his hands now, even if the other party is a dead soldier, he can make the other party speak obediently. One of the easiest ways to do this is to use the magic potions you brought back this time to achieve your goals.

For example, the elixir that the Aurors used for interrogation in the Harry Potter world?
