Mr. Weasley, the three of them came to Zhang Xu for the purpose of opening a broomstick shop.

With the energy of the Weasley family, it was not difficult to buy a shop in Diagon Alley, but how to run a shop was a first for their family.

Zhang Xu didn't know much about this aspect, so he just told them about some price wars and marketing promotions, and let them explore it slowly.

At dinner time, Zhang Xu and the Weasleys, as well as Harry and Hermione, had a big meal at the Leaky Cauldron Bar.

After dinner, Zhang Xu gave Hermione a large bag of small dried fish to use to tease her pet cat she had just sold.

Ron warmly welcomes this, as he thinks the cat won't eat his rats after they've eaten the small dried fish. So he also asked Zhang Xu for a pack of dried fish, planning to stuff the cat with dried fish as soon as he saw it.

After dinner, Zhang Xu went out for a stroll.

Diagon Alley at night is occasionally haunted by wizards peddling strange things, which are distinguished by their hoods that make their faces invisible and their voices, which you can tell if they have been magically altered.

And these wizards don't just pull a customer on the road and sell things, they only sell items to those who also hide their heads and faces.

Not a few steps after Zhang Xu put on his hood, a person who was also wearing a hood found him.

"Dude, do you want poison? I have no poison here. The hooded man whispered to Zhang Xu.

Zhang Xu had a mouthful of groove in his throat and didn't spit it out for a long time.

The hooded man who sold the goods seemed to know what the customer in front of him was thinking, and explained in a low voice: "This herb tastes extremely bitter, and if you eat it, you will not be harmed by it, but you will not be arrested for it." ”

Zhang Xu seemed to be somewhat familiar with this poison when he heard it.

Then the hooded man took a few sticks of hay from his sleeve and said, "Discounted price, one Galleon." ”

Zhang Xu looked at the Ning Shen Grass in the hooded man's hand, which was exactly the one he gave to the bookstore manager a few days ago.

Sure enough, there is no shortage of talents in the world who find business opportunities.

I just hope he doesn't meet Hogwarts students who have graduated in the past two years, otherwise he might be beaten up.

Rejecting the hooded man in front of him, Zhang Xu walked a few more laps and found that there was nothing good tonight, so he went back to the cauldron bar to sleep.

Early the next morning, Zhang Xu didn't wait for the Weasleys, Harry, and Hermione, and took a taxi to the train station alone.

As soon as he walked into the platform, Zhang Xu found a stranger in front of the steam locomotive who was out of place with the students of Hogwarts.

The stranger was dressed in a new, well-tailored wizard's robes and carrying a suitcase that was also brand new. He had a sickly face, but he was in good spirits. He still looked young, but his neatly combed pale brown hair was already mixed with gray hair.

"It's a pleasure to see you here, Professor Lupin." Zhang Xu stepped forward to greet him.

"Ah, hello, Mr. Zhang." Lupin stretched out his hand and shook Zhang Xu's hand.

"The new robe fits perfectly." Zhang Xu looked at Lupin's robe and said.

"Thank you, Professor Dumbledore, for paying a large amount of my salary in advance, otherwise I would have to continue to teach students in patched robes." Lupin said with a little emotion.

"Starting this year, we, the new professors, will be able to pay two months' salary in advance before the start of the semester. Now Hogwarts is not short of money, and the professor's salary and bonus have been rising in recent years. In the past two years, the income from treating squibs alone has been enough to increase the salaries of professors several times. Zhang Xu said.

"'We'?" Lupin caught a certain word in Zhang Xu's words, "Are you going to be the acting professor of a certain course?" ”

"Yes, but we will know which one it is at the opening banquet." Zhang Xu said with a smile, "Anyway, I'm not the acting professor of the Defence Against the Dark Arts class. ”

Lupin smiled and didn't speak.

The two talked as they walked and came to the last carriage of the train.

After Lu Ping put down his suitcase and sat down, he said to Zhang Xu: "Mr. Zhang, how sure do you think you are about treating werewolves?" ”

After making a fortune on the Squib, Dumbledore began to lead Hogwarts into the medical field. Moreover, it also specially selects incurable diseases such as "ancestral psoriasis, specializing in the treatment of old Chinese medicine".

After treating the Squibs, Dumbledore opted for the more difficult treatment of the Werewolf.

A year ago, Dumbledore began a plan to treat werewolves with integrated Chinese and Western medicine. So far, this plan has achieved phased results, and it is just a matter of clinical trials.

As a result, Lupin, as an experimenter and defence-the-dark arts professor, was recruited by Dumbledore to Hogwarts.

Zhang Xu really didn't know about this kind of treatment that was too high-end, he was still involved as a clerk and liaison, and he could only see from the report that the chance of a cure was eight to ninety percent.

After getting Zhang Xu's answer, Lu Ping breathed a sigh of relief.

Over the years, the werewolf problem has pitted him badly.

No one wanted to hire a werewolf, so Lupin had to work part-time jobs like the other werewolves to make ends meet.

If you can get rid of the state of werewolves, I believe that the vast majority of werewolves will pay all the price for it.

After the two chatted for a while, the train started with a "dirty ......".

Not long after the train started, the carriage door was pulled in.

Lupin turned his head to look in the direction of the car door, and then the whole person froze.

Zhang Xu also looked over to the side of the car door and found Harry's trio standing in front of the car door.

"Yo, Harry." Zhang Xu greeted Harry, "This is Professor Remus John Lupin, the new Defence Against the Dark Arts professor. ”

As soon as Harry heard Lupin's name, his eyes lit up, and he walked into the carriage and said to Lupin excitedly, "Professor Lupin, I'm Harry Potter." I heard you're a good friend of my father? ”

Lupin, who was excited to see the son of his deceased friend, and Harry, who was even more excited, were stunned for a while and didn't know how to react.

Zhang Xu said on the side at this time: "The matter of the four of you in the school, Professor Scarlett and Harry have talked about it. ”

Zhang Xu and Harry suddenly trembled when they saw Lupin hear the name Scarlett.

This made Zhang Xu's gossip heart uplifted, it seems that what Scarlet said about beating the four of them back then is indeed true, it seems that the beating is not light.

"Sister Scarlett is really ......," Lupin shook his head helplessly and smiled.

After Lupin beckoned Harry to sit down, Harry couldn't wait to ask about Sirius Black.

Lupin thought for a moment, and then told Harry about the murder of the Potters.

Zhang Xu kept an eye on Ron's pocket as he listened to the story, wondering if Peter Pettigrew escaped at this time, if he would simply settle this year's matter on the train.

As a result, until Lupin finished telling the story of the year, the mouse did not escape.

Just then, the train stopped.
