"Grindelwald?" Dumbledore frowned, looking at Grindelwald who had appeared on the roof of Hogwarts at some unknown time.
In other words, his lover had left Nurmengard at some point, acquired a wand, and even came to Hogwarts, all without his knowledge.
Kaisen in the office, however, didn't have so much internal drama; he quickly ran towards the elemental synthesizer, as the magic seed had already been completely crafted at this moment.
The moment it was held in his hand, General Kaisen's timeline was reconnected, and the time rules from this world finally discovered this time ghost.
"Destroy him!" General Kaisen instantly regained clarity, and then he felt the strong pull of the timeline on him; understanding this, he quickly shouted towards Kaisen.
"No... it cannot be destroyed..." Grindelwald, standing on the roof of Hogwarts, shook his head imperceptibly; the next moment, a bolt of lightning struck down from the sky towards him.
This was the last magic General Kaisen cast; immediately after, he was entangled by time chains that had emerged from behind him at some unknown point, dragging him towards the timeline behind him.
The moment General Kaisen disappeared from this timeline, pixel flames were about to ignite in Kaisen's hand, and at the same time, the ender crystal flew towards the elemental synthesizer.
"Bang!"
The magic seed was quickly annihilated by the pixel flames.
The ender crystal flying towards the elemental synthesizer, however, was blocked by a thin figure.
"What are you afraid of?" Grindelwald asked calmly.
"Move aside, sir, that thing behind you is not good," a staff appeared in Kaisen's hand.
"Are you afraid of sacrifice?" Grindelwald asked.
"What sacrifice, Gellert?" Dumbledore appeared in front of the French window; he knew Grindelwald was a Seer, but he was utterly confused by the mention of sacrifice.
"A greater cause, Dumbledore, the magic seed, which can make the whole world a world of magic users," Grindelwald replied.
"I'm sorry, you won't be taking this thing today; honestly, I spent a lot of effort to correct that so-called mistake..." Kaisen held the staff in one hand, while the other hand was in his pocket, holding a redstone remote control.
At the same time, the Heavenly Dragon Slaying Cannon suspended above the office also imperceptibly lit up with purple light, and ender crystals continuously stacked up in the pool.
An explosive arrow was already poised there, waiting only for negotiations to fail so it could destroy the machine as quickly as possible.
Even the machine itself wasn't important, as long as the enchantment book within the machine could be destroyed.
"Are you afraid of sacrifice... Professor Kaisen... May I call you that?" Grindelwald asked.
"Whatever."
"You fear sacrifice, you fear that future of sacrifice, but strictly speaking, that future is not your fault, and the benefits outweigh the drawbacks; compared to everyone in the world having a spark of magic... it's merely a billion people, even three billion, it's not an unacceptable price."
Grindelwald put his wand back into his pocket, spread his arms as if embracing the sky, and said.
"This kind of sacrifice without a bottom line will sooner or later lead to the extinction of all humanity..."
"It's not without a bottom line; the source of that future is not some ambitious person, or you, but the lack of someone who can unite those magic-wielding rabble, and unite them again!"
"Do you want to be that person? Or will Dumbledore be that person?"
"I think... you can," Grindelwald said.
"I know my own limits, I've read a lot, you can't fool me," Kaisen's hand, holding the remote control in his pocket, tightened.
"So, there's nothing to discuss then? Dumbledore?" Grindelwald shook his head helplessly, then looked at Dumbledore, who stood between the two.
"This is a greater future, we can be together again!"
"... Gellert... we are old."
"But he's not old!" Grindelwald pointed in Kaisen's direction: "He's still young! He possesses such remarkable talent, but what is he doing now? Being a small Professor at Hogwarts? Playing house with you and your pawn called the Savior within the school grounds?"
"..... Albus... This is the last time... I beg you, stand with me again," Grindelwald said with a sorrowful expression.
"....." Dumbledore was silent for a moment, then moved; he walked towards Grindelwald, who, upon seeing this, revealed a smile.
Just as he thought victory was assured and the world was about to become greater, Dumbledore stood directly opposite Grindelwald, facing each other, eye to eye.
"Gellert, leave here."
Grindelwald's expression instantly became somewhat lost.
"Do you really feel that way?"
"Leave here... stay away from Hogwarts, stay away from my Professor, and stay away from this machine too," Dumbledore said.
"... Dumbledore... You really are old," Grindelwald shook his head helplessly; the next moment, a pale purple spell flew directly towards Dumbledore's face.
Boom!
"Is that all you can do, these little tricks?" Dumbledore said with a cold face.
"Of course not."
The next moment, a brilliant blue flame erupted directly from around Grindelwald, instantly forcing back the Grindelwald closest to him, then he cast magic to shrink the elemental synthesizer and pack it away.
Kaisen, standing on the periphery, waiting for negotiations to break down, finally seized the opportunity and pressed the redstone remote control in his pocket.
As the ender crystal was detonated, the enormous impact, carrying the arrow, almost instantly struck the shrinking elemental synthesizer.
Bang!
Grindelwald was blown away by the explosion.
Kaisen quickly scurried over, picked up the magic seed enchantment book from the ground, and burned it to ashes with a burst of flame.
"Heh heh... It's been over a hundred years... I've never seen anyone install a cannon on their office ceiling as a chandelier; that Dumbledore would hire you as a Professor shows that his preferences haven't changed all these years."
Grindelwald, propping himself up on his knees, said to Kaisen, drawing a cold breath.
"Yeah, you don't need to tell me, he's always liked the rebellious type," Kaisen waved his hand, and three Decay Skulls were poised behind him, ready to strike.
