Harry searched the chamber for almost two hours, from the floor to the walls to the ceiling, but found nothing.

On the other side, Zhang Xu, who pretended to be trying to find clues, but actually touched the fish all night, was already yawning there.

"No clues were found tonight." Harry said to Zhang Xu with a little unwillingness.

I tossed so hard at the beginning of tonight, but in the end I didn't get anything.

"I think you should bring Professor Dumbledore with you next time." Zhang Xu said to Harry, "Maybe he can find something we didn't find." ”

Harry felt that Zhang Xu had a point, and after seeing the slightly tired look on his face, he decided that tonight's action would end here.

After finishing this anticlimactic operation, Zhang Xu went back to his dormitory to wash up and sleep, and the little clue found in the passage made the Harry trio think.

For some other things, I will wait for Zhang Xu to go to Lao Deng when he is free and ask him what he thinks.

The days that followed were back to normal.

Hogwarts students had their first Quidditch match of the school year.

Outside of school, the only good news was that the new knight bus was in operation, and nothing else could have made the wizards happy.

Since the last search in the Chamber of Secrets had been almost fruitless, the Harry trio had stepped up their surveillance of Malfoy.

Hermione, who was not very interested in Quidditch, even found an excuse such as not feeling well not to watch the match between her house and the Snake House, but instead snuggled up in her dorm room with a map of the living point to observe Malfoy's actions.

After Voldemort's public appearance at the end of the last school year, Dumbledore and the Ministry of Magic went through a series of deals, with most of the education orders issued by Fudge, then Minister of Magic, and most of the orders of Senior Investigator Percy Weasley revoked. However, both sides forgot to revoke Percy's ban on Draco Malfoy for life.

Even if Malfoy now gets a medal of the Order of Merlin, the ban is still in effect. During this time, Malfoy wrote to the Ministry of Magic to report the problem, and all the letters ended up in the mud.

In Harry's eyes, almost the best time for Malfoy to make trouble was when almost the entire school watched Quidditch.

As a result, Hermione saw on the map that Malfoy had not taken a step out of their house's common room, and only saw Zhang on the balcony of the corridor for a long time teasing Lady Loris and Crook Hill, and Lai Fu running to the top of the Astronomical Tower.

Late at night, the trio of Zhang Xu and Harry, who had received approval from the Vice Chancellor Professor McGonagall to attend the Ferenze wedding, were returning to Hogwarts Castle after attending the wedding.

The centaur wedding was an eye-opener for the Harry trio, with a variety of fruits and mushrooms that are hard to come by.

As for why there were tropical and subtropical products such as sugar cane, pineapple, watermelon, pomelo, mangosteen and shakya at the wedding banquet, Zhang Xu asked the three of them to ask Scarlett to go.

The group walked and chatted in the Forbidden Forest, and the conversation shifted from today's Quidditch match to the Lion Yard chaser Katie Bell, who was injured by the opal necklace.

Harry, captain of the Lion House Quidditch team, recently wrote to Katie Bell to check on her condition, and he told a few people around him: "Katie Bell was well cared for after being taken to St. Mungo's Hospital for Magical Injuries and Injuries, and now she is recovering quickly, and she will probably be back after the Christmas holidays." ”

"Have you found the murderer?" Zhang Xu asked Harry.

Since Katie Bell's accident, the students at Hogwarts have once again embarked on a collective journey to solve the case, and the Harry trio has been involved in many cases.

It's just that Zhang knew the murderer early on, and it was only more than 260 days before the college entrance examination, so he didn't get involved.

Now I don't know where this group of tried and tested students has come, so Zhang Xu asked curiously.

"You're one of the suspects." Hermione said to Zhang Xu.

Zhang Xu, who was dumbfounded, almost spit out a mouthful of old blood.

"Why me?" Zhang Xu asked confusedly.

"Because no one has seen you anywhere else in Hogsmeade when someone gave that necklace to Katie Bell." Hermione explained to Zhang Xu.

Looking at Zhang Xu in a daze, Hermione continued to explain: "We spent a long time doing the investigation, and most of the people who went to Hogsmeade had more than two people who could prove that the other party was not in the women's bathroom of the Three Broomsticks Bar at the time. ”

"And the few people, including you, don't have an alibi at the time."

"It's good, it's powerful." Zhang Xu nodded and said to Hermione, "This method of relying on the masses and mobilizing the masses to conduct a gradual investigation is very good, I think the prisoner is likely to be among the suspects you have found." ”

Then Zhang Xu looked at Harry and asked, "Looking at Harry's actions, I think Malfoy is also among them, right?" ”

"Malfoy said he took a detour from the neighborhood to the Owl Post Office, but very few students would go to the neighborhood, so there were no witnesses to prove whether his words were true or false." Hermione replied.

"And what about the others?" Zhang Xu asked.

Hermione, who clearly played a huge role in the investigation, went into detail: "There was a couple who claimed they were upstairs at the Pig's Head Bar and the owner of the Pig's Head Bar refused to answer any of our questions. ”

"There was a seventh-grader who claimed to be looking for a house to rent in a residential area and was going to move in after graduation."

At this time, Zhang Xu was sure that the students had not communicated with the Aurors, otherwise they would have been able to narrow down their targets to Zhang Xu and Malfoy.

"I think the guy looking for the house is innocent." Zhang Xu said to Hermione, "He asked me if my house was rented. ”

"What about you?" Hermione looked at Zhang Xu and asked, "No one has seen you for a long time that day." ”

"I was on the second floor of that café at the time, and the waiters in the café were all able to testify for me." Zhang Xu said.

Zhang Xu's ability to go up to the second floor of the café was something that many people knew and envied and hated, and as soon as he said this, Hermione believed it.

Zhang Xu continued, "Have you ever thought about the Imperius Curse or the Compound Potion? If the real killer uses both methods, then there is a high chance that someone else will be scapegoated. ”

"So now our investigation is deadlocked." Hermione said, "Now we can only guess at the murderer's target, and then work backwards to figure out who the killer is." ”

Hearing this, Zhang Xu was relieved, no wonder Harry chased Malfoy's ass to investigate, while Hermione and Ron's opposition was limited, it was because Malfoy's motives were sufficient.

"Who has such a mortal feud with whom in the school now." Zhang Xu said.

At this time, Ron, who had been beside him and didn't talk much, said "hehe" twice.

Hermione glared at Ron and said, "Say what you know, don't act like you know but don't want to say it." ”

"It's okay on my side, it has nothing to do with it." Zhang Xu said to Ron.

At this moment, Hermione and Harry were both confused by Zhang Xu's words.

"You just spared them?" Ron asked, surprised.

"That's enough to get to this point." Zhang Xu replied.

Ron said "oh" and stopped talking.

Hermione looked at the two people playing dumb riddles, and didn't know what to say for a while, this kind of situation didn't just happen to Ron, many students of the magic family - including Neville - had similar behaviors, and everyone was tacitly aware of something. But whenever Hermione asked them, they were tight-lipped.

The grievances and grievances between Zhang Xu and those families can be seen by other families, but Zhang Xu didn't want to make a plot about when the grievances will be retributed, so he troubled Dumbledore to come forward to control public opinion.

Zhang Xu glanced at Harry, who was also confused, and said to him: "If you want to know about this matter, you can ask Blake, I think he should know about it." ”

Regardless of Hermione, who was about to go crazy, Zhang Xu turned the conversation to the matter of preventing the next attack.

At this time, Zhang Xu and his party had already walked to the edge of the Forbidden Forest, and they suddenly saw a figure moving in the moonlight, and the possibility of Hagrid was ruled out from the size of the figure.

Zhang Xu and the others took out their wands one after another, and then scattered and surrounded them from several directions.

The figure stood in the shade of a tree that could not be illuminated by the moonlight, so that Zhang Xu and the others could not see each other's faces clearly.

The next moment, four spells shot at the figure at the same time.
