In the quiet principal's office, the three of them had their own thoughts.

Dumbledore must have been thinking about how to protect Harry Potter.

Harry must have been thinking about how to get revenge on Voldemort.

And Zhang Xu was thinking about how to trap Voldemort while not pitting Harry too badly.

In the end, it was Zhang Xu who broke the silence in the office first.

"Harry, I remember you told me before that at the end of your first year, Quirrell, possessed by Voldemort, would hurt you when he touched you?"

"Yes," Harry said in reflection, "his hands were like they were burning so I could get out from under them, and here you are." ”

"It's the magic of love that Lily left on Harry when she died, a magic that kept Harry alive and restrained Voldemort." Dumbledore said.

"So if Voldemort used Harry's blood to restore his body, would the magic still work?" Zhang Xu asked Dumbledore.

Dumbledore frowned and thought for a moment, then shook his head and said, "It won't work anymore." ”

"In this way, Voldemort's blood against Harry is inevitable." Zhang Xu also sighed and said.

Dumbledore nodded, and Harry couldn't sit still.

Zhang Xu thought for a while, and then cautiously said to Dumbledore: "Professor, there is a way to make some kind of bug parasitize Harry's blood, and if Harry usually drinks certain potions, he will be fine. And people who are parasitized by bugs will get some benefits, but there will also be a small price. If Voldemort used Harry's blood to restore his body, then the bug would parasitize Voldemort's blood. Voldemort didn't have this potion to drink, and after these bugs rioted, it was enough to cause great damage to Voldemort, and even if he relied on other potions to repel worms, the damage would be irreversible. Eventually, Harry was able to kill the bugs in his body with a special potion without any harm to his body. ”

Dumbledore immediately understood what Zhang Xu meant, this was planning for the worst-case scenario.

And Dumbledore was also in a dilemma at the moment, after all, this method was also risky.

"So what are the benefits and costs?" Dumbledore asked, staring at Zhang Xu.

"What's good...... Zhang Xu said after looking at Harry, "First, these bugs can increase the host's physique, so that the host won't get sick easily. Second, it can enhance the host's magic at a certain level. Third...... Harry was too young to be needed yet. ”

"What is the price...... Zhang Xu said after carefully looking at Harry, "Harry's height in the future is estimated to stop at one meter six five, which is about five feet and five inches." ”

What Zhang Xu said was a certain Gu worm with a function similar to Jin Yongli's "Three Corpses Brain Divine Pill". This kind of Gu worm was used by some shady groups to control members in ancient times, and it was quite effective under the combination of grace and power.

It was only after liberation that this Gu worm was forbidden to be refined.

However, just like chemical and biological weapons, the production and use of them are openly banned internationally, while the major powers are privately ...... Everybody gets the idea.

Dumbledore frowned and thought for a long time, and finally asked Harry, "Harry, what do you think?" ”

Harry struggled for a moment, then made up his mind and nodded vigorously.

"I agree with this approach." Harry said firmly to Zhang Xu, "I believe that Zhang will not harm me. There's nothing wrong with being able to cause problems for Voldemort and eventually get rid of those bugs. As long as I can get rid of Voldemort, what if I'm shorter. ”

After listening to Harry's words, Dumbledore also nodded to Zhang Xu.

"Since everyone agrees, then I will report it to the country immediately, and I will be able to send it in three to four days." Zhang Xu said.

Zhang Xu naturally wouldn't say that he had stock in his treasure bag, so Dumbledore would have to have an opinion.

Then, Dumbledore took out a pair of things and handed them to Harry.

"It's the portkey." Dumbledore said, "It doesn't usually work, and when you're in danger, you just have to put your magic into it and it can take you to this office." ”

Then Dumbledore smiled at Zhang Xu and said, "This is thanks to Mr. Zhang's advice." ”

Harry was embarrassed to hold a pair of insoles, flipping through them.

"Ahem......" Zhang Xu said to Harry, "this portkey is a little problematic, but you have to clean it often, otherwise the smell of it will kill Rifou hiding inside your shoes." ”

Harry changed into a portkey insole on the spot, and then left the Headmaster's office with Zhang Xu after Dumbledore said a few words to be safe.

Harry and Zhang Xu walked together in the corridors of the castle, and the two chatted about Ron and Cedric, who had recently been tormented by special training.

Suddenly, Harry asked Zhang Xu, "Zhang, what is the third benefit you just mentioned?" ”

Zhang Xu glanced at Harry and said, "You and Ginny are not over sixteen years old, you don't need this kind of benefit." ”

Harry was stunned for a moment, then his face turned red.

Looking at the "refreshed" Harry, Zhang Xu felt a little guilty, and bringing an innocent teenager like Harry to the driver's seat seemed to go against the conservative school spirit of Hogwarts.

Although Hogwarts is not against early love, the things that cross the line are still dealt with together, especially if they are not old enough, they are basically punished heavily. So only a few students with guts sneak around.

Mr. and Mrs. Weasley walked outside the castle until four o'clock in the morning? Zhang Xu was hehe.

Even Peeves and their ghosts pretended not to see this kind of thing, and then kept their mouths shut. Filch also told Zhang Xu that as long as the students are not too excessive, or his mood is too bad, he will also close his eyes. After all, Filch is also someone who has a girlfriend. Percy was caught that day, and it was only because he ran into Filch who was in a bad mood that day.

Many people know about Zhang Xu and Fleur in private, but because of various reasons, coupled with Dumbledore's connivance at Zhang Xu, everyone doesn't say anything.

After a while, Harry suddenly remembered something, and said to Zhang Xu: "Zhang, Krum invited Ron to bring his friends to the Beauxbatons ship on Sunday, Ron wants to go with you and Fleur in addition to a few of us Gryffindor, but you have been too busy to find you recently. Will you be free then? ”

Zhang Xu replied, "Krum has also invited Fleur, and Fleur and I will go with us then." In addition to this, he invited Cedric. ”
