The Harry Potter trio took the baskets of apples and plums that their classmates had picked together to the Centaur tribe to hand in their tasks, and then the group returned to Hogwarts Castle happily with a basket of packaged medicinal herbs.

When they returned to the castle, they saw Professor McGonagall and Zhang Xu talking in front of the gate.

Zhang Xu had just taken his harvest to the Potions classroom in the basement and handed it to Slughorn, and met Professor McGonagall on his way back to the foyer.

Recently, Old Deng was gone, and Professor McGonagall was in charge of everything, so Zhang Xudi reported to her the movements on the Centaur side and asked her to relay it to Old Deng.

"Do the horses have enough food for the winter?" Professor McGonagall asked, a little worried.

As the Deputy Headmaster of Hogwarts, she naturally understands the importance of the Centaur tribe to Hogwarts.

Zhang Xu replied unoptimisticly: "Judging from the number of unpicked fruits so far, although the horses will not starve to death this winter, they will definitely not be as abundant as before. ”

Centaurs eat about three percent of their body weight each day.

And the size of the centaurs is huge, and the weight of an adult centaur like Ferenze is more than 500 kilograms, and the 300 pounds of loli in the tribe run all over the streets.

Due to the high altitude of the Forbidden Forest and the long duration of winter, the horses will not be able to gather food on a large scale until the end of next spring, so they need to stock up on nearly five months of winter food from mid-November to April.

In this way, each adult centaur must prepare two to three tons of food to survive the winter, so the food required by the entire centaur tribe for the winter is very large.

"If we go and help the horses gather food...... Professor McGonagall frowns and begins to ponder the feasibility of this.

"I don't think it's a good choice," Zhang Xu said, shaking his head, "maybe the horses will have the illusion that we are breeding them, and there are already horses today who have such an illusion." ”

Professor McGonagall was also very helpless about this, and it was difficult for her to meet such an ally who did not agree with her.

Professor McGonagall decided to take the matter to Dumbledore.

At this point, Harry and the others returned with the herbs.

Dividing line

Shortly after dinner, news that Katie Bell had woken up after receiving treatment instantly spread through the common rooms of the four colleges.

Now Zhang Xu shirked a lot of things on the grounds that he needed to recuperate, so he naturally had to go to Madam Pomfrey regularly to check it up, and then take some auxiliary medicines to drink as health products.

Zhang Xu, who had just left the school doctor's office, also went to the ward to visit Katie Bell just now, but although she woke up, she didn't have any energy, and she quickly fell asleep under the effect of Madam Pomfrey's auxiliary medicine.

As for the fact that Madam Pomfrey gave Zhang Xu and Katie Bell auxiliary potions were poured out of the same large bottle, Zhang did not know.

After returning to his dormitory, Zhang Xu went to the study, took out a thickly folded map from a brown paper bag and spread it on the desk.

After hearing the prophecy of the centaur elder today about the mechanized troops sweeping the Forbidden Forest in an air-ground coordination, Zhang Xu suddenly realized that there was a problem he hadn't paid attention to for so many years, and that was the terrain around Hogwarts.

Due to the wizard's unscientific mobility, Zhang Xu has always ignored this point

Although Hogwarts' magic makes it impossible to mark on the map, it is not difficult to find the location of Hogwarts on the map, especially the topographic map, through indirect methods. Zhang has long determined the latitude and longitude of a circle around Hogwarts through GPS positioning, as long as these coordinates are connected into a circle, so that the location of Hogwarts can be known.

For various reasons, Zhang Xu did not talk to Dumbledore about this method.

As can be seen from the topographical map, the area where Hogwarts Hogsmeade is located is located in a basin between several alpine mountain ranges, surrounded by mountains on three sides, and only the Forbidden Forest side is not only not blocked by high mountains, but also relatively flat.

Zhang Xu carefully studied the topographic map for the first time from the perspective of a Muggle attack on Hogwarts, and soon found that the relatively flat Forbidden Forest was the only option to attack Hogwarts on a large scale, which was "surrounded by three mountains".

After confirming it at this time, Zhang Xu put it aside and ignored it.

If things really develop to that point, it is not something that he can solve alone.

After packing up the things on the desk, Zhang Xu opened the door of the study and returned to the living room, and the moment he walked into the living room, a sweet smell of apples poured into his nostrils.

Scarlett, who was sitting on the couch, waved at him, then gestured to the coffee table.

Zhang Xu walked over and found that the aroma coming out of the coffee table was a huge apple pie.

Scarlet cut a few pieces of apple pie and put them on a small plate, handed them to the Harry trio sitting around the coffee table, and finally divided a piece for himself and Zhang Xu.

Zhang Xu looked at the four people who didn't know when they appeared in the dormitory living room with a confused expression, picked up his share of apple pie and ate it.

Just as confused as Zhang Xu was the Harry trio, the three of them originally came to Zhang Xu for something, but they didn't expect that it was Professor Scarlett who helped them open the door after knocking on the door.

Now Harry was wondering if they should find an excuse and run away quickly, as if nothing happened tonight.

For a moment, the atmosphere was a little weird, and Scarlet was talking about how she had left a lot of apples with a few girls, and had just made a lot of apple pies in the kitchen. And the other four people silently ate the sweet apple pie with their own thoughts.

It didn't take long for Zhang Xu to finally find a topic to break this atmosphere.

"Harry, can you still dream of what Voldemort saw and heard lately?" Zhang Xu asked.

Everyone here knew that Harry had a relationship with Voldemort, but recently Harry didn't mention such a thing, and everyone didn't pay attention to it.

"Nope." Harry shook his head and said, "Professor Dumbledore said he closed his brain with Occlumency, and he realized that it was a double-edged sword for him. ”

"That's a pity," Zhang Xu said regretfully, "It turns out that I still plan to let him see some good things." ”

As the saying goes, if Voldemort can show Harry a small video of Blake being caught and tortured by them, why can't Harry return the favor in the same way?

Zhang Xu even wrote the script:

In the foyer of Hogwarts Castle, standing across from Voldemort was the tall and burly Hagrid.

Hagrid: "You're back, I've been waiting for you for over fifty years. ”

Voldemort: Σ(ц|||)

Hagrid: "It's been over fifty years, and I knew what that monster was from the beginning, and Aragog told me who it really was. ”

Voldemort: (ц)"

Hagrid: "I know you'll be homeless without Hogwarts, and I'll have a place to stay." That's why I let you know that I'm secretly raising Aragog so that you can stay at Hogwarts. ”

Voldemort: o((⊙⊙))o

Hagrid: "For more than fifty years, I want you to understand that I ......"

Voldemort: (°Ц°)┻━┻

……

Zhang estimated that there was a certain chance that Voldemort would be able to drive him crazy.
