Chapter 240

Harry woke up from the bed, sorted out his thoughts a little, and hurried to the front of the train to knock on Deng Buliduo's door.

"Harry, did you see it?" Deng Buliduo's tone had some expectation. "Did Snape tell Voldemort about the Elder Wand?"

"Right," Harry nodded. He realized that it was Deng Buliduo who deliberately told Voldemort this information.

"Did he go to seek a more powerful wand?"

"No, he still believes in his old fellow," Harry said, panting. "He plans to deal with you with that yew wand first, and then suddenly take out the laser wand to sneak attack you."

"Very consistent with his personality, arrogant, proud, covering up inferiority," Deng Buliduo sighed. "Looking at it this way, I have to rely on myself to deal with him."

"Right, he is very cunning," Harry said. "He let Professor Snape confirm that all members of the Order of the Phoenix and the doctors appear on the Hogwarts battlefield before he will make his move in Tranzero."

"It doesn't matter; I'll deal with him," Deng Buliduo said. "He is powerful; more wizards coming will only increase sacrifices."

"Can we let the doctors ambush in the surroundings, and Professor Snape pretends they have appeared?" Harry asked.

"This won't work; Voldemort is very cautious in such matters; he doesn't even necessarily trust Snape; he might have other ways to confirm," Deng Buliduo said. "If we really do this, then perhaps Voldemort will run away immediately and turn to kill Snape."

"I think we need to discuss with the doctors how to appear on the battlefield and appear in Tranzero at the same time," Harry said seriously. "Voldemort playing such tricks has only one reason, and that is he is afraid; he is afraid of twelve doctors ambushing him together."

"And since he is afraid, we have to find a way to do this," Deng Buliduo nodded. "Let's go, let's go see Barty Jr. together."

When Barty Jr. saw Deng Buliduo and Harry coming together, he raised his eyebrows high, then locked the office door without a word and chanted a spell toward the door in a low voice.

"Professor Deng Buliduo, since you are here too, it means this matter is of great importance," he said. "Please tell me, what's wrong?"

"You need to go and support Hogwarts," Deng Buliduo said. "Only after confirming this will Voldemort launch his attack."

Barty Jr. said with an indifferent face: "It doesn't matter; we can open the TARDIS and go there after fighting."

"I participated in the production of the TARDIS; I must remind you," Deng Buliduo said seriously. "The space travel part of the TARDIS is based on Apparition; the Anti-Apparition Ward will also resist the TARDIS. You are unimpeded at Hogwarts because I registered the TARDIS as a female student."

"Is that so?" Barty Jr. looked a bit surprised, then he immediately changed to a frowning expression. "Let me think..."

Actually, Harry himself could think of many methods, such as finding a few people of similar build to wear the doctors' clothes, finding people to take the doctors' Polyjuice Potion, or anyway, the Death Eaters might not know the doctors' appearance, so casually finding some wizards and insisting they are doctors wouldn't matter.

But these methods all have flaws. As Deng Buliduo said, Voldemort will be extra cautious in such matters that require taking risks. He might have many ways to identify the truth of the doctors. Harry also didn't dare to bet that the Death Eaters didn't know a certain doctor, because once it failed, not only would the efforts made for this plan for a long time be wasted, but Snape, this undercover agent deeply trusted by Voldemort, would also be exposed.

"I thought of it, instant soup," Barty Jr. clapped his hands suddenly. "You give me that painting."

"What painting?" Harry was stunned for a moment.

"Stasis Curse, you told me about it," Barty Jr. said. "After the battle at Hogwarts ends, we use the TARDIS to return to before the competition starts, and then hide in that painting."

Harry's eyes gradually brightened.

"You bring the painting in from the start of the competition, strictly control the time, so that we can come out of the painting at the critical moment and immediately join the battle," Barty Jr. described this process. "For example, the competition starts at nine in the morning, and the time you break through the obstacles to reach the last level around nine-forty is more appropriate. Then we set ourselves to appear at nine-forty. Even if you can enter the last room early, you must wait until nine-forty to go in."

"But Voldemort won't know when I finish the task; he will definitely ambush there in advance," Harry said. "By then, even if you appear together unexpectedly, he can just run away at worst."

"That is to say, we have to ambush before Voldemort comes," Barty Jr. pondered. "But when will Voldemort come?"

"He will only make his move after confirming that you appear on the battlefield, but the Battle of Hogwarts must be fought after the competition starts," Harry analyzed, and Deng Buliduo revealed an encouraging look. "If they attack Hogwarts before the competition starts, then the competition can be postponed, and everyone can go to support Hogwarts together. So the timing of their attack on Hogwarts must be after the competition starts, or when it has been going on for a while. At this time, everyone's attention is on the competition, and Deng Buliduo won't have time to rush back and rush back again."

"Then, the time Voldemort gets the news from the Hogwarts battlefield is generally after nine o'clock. You need to come out of the painting before nine o'clock and find a good place to ambush," Harry concluded.

"If Voldemort prepares to come in advance to ambush you, then he will enter our ambush circle," Deng Buliduo said with a smile. "Perhaps, before you arrive, we have already subdued him and left calmly; you can even complete this task."

"But this requires us to arrange many places convenient for hiding and ambushing in the last room of the third task, and we also have to put the painting in in advance," Barty Jr. scratched his head. "But it doesn't matter; this matter can be solved; after all, the head referee is also our person."

"Prince Mountbatten?" Deng Buliduo nodded. "He was a member of the Department of Mysteries when he was young; it seems that organizing the doctor project has rekindled his fighting spirit."

"I will give the painting to him before the competition," Barty Jr. said. "Now we need to conduct some calculations in advance, and experiments; we have to adapt to the feeling in the painting first, and we have to grasp the time accurately, which is very necessary."

"Still good, Harry, still good," Barty Jr. revealed a look of relief. "You don't have to risk using the Time-Turner, but you can keep it as insurance. In case, I mean in case, Voldemort defeats the thirteen of us, you can still use it to complete our last wishes."

"Thirteen, but aren't there only twelve doctors?" Harry asked subconsciously.

"Because I will also be there," Deng Buliduo said calmly. "You can keep the Time-Turner as a souvenir, because with me there, there won't be an 'in case'."

"Oh right, there is one more thing; should we tell the students the time Hogwarts is attacked?" Harry asked. "This can let them avoid disaster in advance—or we can just let them have an early holiday."

Deng Buliduo fell into deep thought. After a long silence, he raised his head and said slowly: "No."

"We can't do this," Deng Buliduo said. "We can't expose what information we know; it's very likely that this will alert the enemy and cause that worst situation."

"Even if we reason according to the most basic, most shallow information," Deng Buliduo said. "Voldemort knows we are tempting him to attack and kill Harry, and also knows I will ambush him. However, we shouldn't know he is preparing to attack Hogwarts. Even if we know, and guessed the purpose of attacking Hogwarts wrong, thinking he intends to distract me, how do you think Voldemort will consider me?"

"What do you mean?" Harry was a bit puzzled.

"The Deng Buliduo in Voldemort's imagination, if he evacuated the students in advance, then that Deng Buliduo must be inviting him to go to Hogwarts for a final battle; this is the Deng Buliduo in his mind who would do this to protect Harry," Deng Buliduo said. "Because once we are prepared, Harry can have many ways to escape; what can't run away is Hogwarts school, which will change the ideas of both sides to another direction, a direction that will undoubtedly cause many innocent casualties."

"But if he didn't see me at the evacuated Hogwarts," Deng Buliduo said conversely. "It means I know more information than he thinks I should know, then it returns to that worst situation."

Harry thought a little and agreed with Deng Buliduo's analysis, but asked puzzledly: "But if we fight at Hogwarts now, won't it still cause innocent casualties?"

"If the main battlefield is not at Hogwarts, the Death Eaters won't fight with all their strength," Barty Jr. interjected. "The defensive magic of the professors and the school should be enough to drag them for at least four hours; by then, we must have already solved Voldemort."

"Perhaps we have another way," Deng Buliduo said. "Count which students are willing to watch the third task on the spot, and then... no, not suitable; let the students come spontaneously, but this will cause truancy, and those students who are afraid of participating in the battle are mostly timid and follow the rules; they won't skip class."

"Perhaps this is the first time you regret that Hogwarts' summer vacation is so late," Harry proposed what might be the only advice in his life regarding the holiday issue.

"Then we can only trust the professors," Deng Buliduo sighed. Clearly, he didn't intend to make any changes to the existing holiday length.

"It doesn't matter; we will appear on the front line of the battlefield as soon as possible," Barty Jr. said. "The faster we end here, the safer Hogwarts will be."

"It seems we can only do this," Deng Buliduo also had no new good ideas.

After this matter was decided, what Harry had to do was very simple. After he went back, he immediately wrote a letter to Sirius, and Sirius also sent the painting over very quickly, along with all his experimental data about the painting.
