"What alternative?" Pei Chen became interested.

"Do you still remember the forbidden area at the end of the corridor on the fourth floor? That is a plan we designed. The things collected in it are the legendary philosopher's stones, which have the power to turn stones into gold and immortality..." Dumbledore explained, paying attention to Pei Chen's eyes by the way, and found that the other party's eyes were clear and fluctuating, so he continued to speak with confidence.

He didn't know how cheap the price of gold was in infinite space, so that Pei Chen now had hundreds of kilograms of pure gold in the storage space. As for the topic of immortality, it was as normal for monsters classified as immortality, as humans needed to drink water and eat.

If only the effects of turning stones into gold and immortality are worthless to Pei Chen, perhaps Unlimited Space would be willing to spend some small money to acquire?

"We have known for a long time that Voldemort was not dead, but was hiding in the dark and waiting for the opportunity. But we have no choice but to do so, because he has no substance anymore, and as you can see, no one can grasp his whereabouts."

"Oh, then I understand, so you should use this so-called philosopher's stone to actively lure Voldemort?" Pei Chen immediately reacted.

"It's right to say that, but we want to test... his reality." Old Deng sighed. To be honest, he just simply felt that Voldemort was in contact with Quirrell, and did not expect that the other party was brave and hid directly in Quirrell's body and entered Hogwarts Castle.

If he had known this news earlier, he would definitely be able to kill Voldemort in one blow - in response to this situation, he would have no chance to turn over again.

There is no need to do too much, just throw more than two Avadasauri curse over it. Even if Qiluo blocks one, the others will still have to be eaten by Voldemort himself. Although he only has residual souls, he is not a ghost in strict terms. He has to kneel down even if he eats the curse that kills the soul directly.

"Well, disturb, Principal Dumbledore, I think we have more important things to do now." Professor McGonagall interrupted the conversation with a frown, looking at the corpse on the ground, meaning it was self-evident.

"Ah, indeed." The white-bearded wizard breathed again. Sure enough, something happened to the teacher of the black magic defense technique. Could it be that the curse is really so stubborn and terrible that no one in this position can teach for a year and there will be no accident?

"Professor Lair, mind giving me the wand in your hand? This may be a very important evidence. We can use the flashback spell to check what kind of spell it released before." Professor McGonagall asked Pei Chen for Professor Quirrell's wand in his hand.

It is said that the wand chooses its owner. After being taken by Pei Chen, the wand has been resisting violently, conveying unwillingness, but they are all suppressed by powerful spiritual power. The first moment after Qiluo declared dead, Pei Chen first realized that the wand was also silent at the same time.

Tsk, mass-produced things can actually have existences similar to spirits?!

Pei Chen sighed, and the white mist condensed in the cold temperature. He handed over Qi Luo's wand, not too much.

"We need some evidence... Uh?" Dumbledore said, waving the old wand with dazzling spell in his hand, but nothing happened. Suddenly, the scene became awkward.

"Ahem, it seems that Professor Lyle is not using magic power..." Old Deng blushed slightly, coughed a few times in a concealed manner, and said, "Retracing magic does not work. There is a strange power that prevents the magic from taking effect. We need to find another way..."

Pei Chen yawned and felt a little sleepy. But he also understood that killing a professor at Hogwarts would be a big deal. It would be a good idea to shock the British Ministry of Magic. If there is no strong proof of escape from crime, he might have to explore Azkaban's plan in advance.

However, he was also very interested in seeing what other methods were, so he did not tell the few people that they could use the spell normally after the large-scale explosion of demon power energy hedge dissipated in the air.

After all, it is the power of different systems, so it is normal to stumbling against each other.

"Professor McGonagall, please watch here. I need to go to the Department of Mystery Affairs in person." Dumbledore said, "I'll be back in an hour soon."

Pei Chen couldn't help but feel a little disappointed, but he was cheered up again. Until now, his interest in this world is getting bigger and bigger. Although he has learned a lot of things, this not only does not give Pei Chen a clear grasp of the essence of the world, but he also feels that it is covered with a mysterious and strange veil—

Judging from the performance, it should be a low-level magic scene, but the foundation it reveals is too strange. Many advanced fields have made significant progress. For example, the soul alchemy brought behind the magic stone, the traceless expansion spell and the space magic knowledge that is looming behind the phantom manifestation.

"A thousand years ago, could this world really be a background of the gods or a world of high demons?"

Pei Chen thought in a tangled way.

...

...

"This is Mr. Thor of the Department of Mystery Affairs and an investigator of this incident." Dumbledore was indeed very fast and came back soon. He also brought a middle-aged man and introduced to Pei Chen, "His specialty is to study the mystery of time magic."

Time magic?!

In an instant, Pei Chen's eyes became very subtle. He hesitated for a moment before he came to his senses and shook hands at the middle-aged man: "Hello, Professor Thor."

"Hello, hello!" Mr. Thor replied with some rush. He seemed to be absent-minded and seemed very rude. Pei Chen didn't care much. He was a genius, and he was always immersed in his own world, but this did not mean that they were unprofessional. For example, Mr. Hawking only had two fingers left to move, wasn't he the best in the world?

"As you imagine, we need official personnel to witness the truth of the matter with our own eyes, so we invited Mr. Thor... and the time converter." Dumbledore reached out and showed everyone a small shiny golden timer with a very long and delicate gold chain.

Time converter?! Pei Chen's eyes widened. There is such a powerful killer in this world with a big trough? Could it be that Doctor Who or Doctor Cat are all people in this world?

"In fact, it is not as useful as you think, otherwise it would not have been used to do small things." As if he had noticed Pei Chen's face change, Dumbledore explained that Snape and Professor McGonagall both looked for granted, and seemed to agree with this statement very much.

"But we are not professionals, so let Mr. Thor explain it to us!"

"That's right." Professor Thor nodded and took the initiative to take the conversation. Perhaps it was involved in his professional field. He instantly escaped from his absent-minded state, becoming radiant and full of energy, and constantly introduced Pei Chen to the mystery of time-

"The essence of the time converter is to encapsulate a [one-hour reverse spell] in a timer, so that the wizard can hang it around his neck and turn it around for a few hours if he wants to reverse it. However, the time reversal spell itself is very unstable. Although many people have great enthusiasm and fantasies about time travel, the travel is very limited."

"Very limited? You mean-"

"Yes, in our current research, the longest travel time that can be achieved is about five hours, otherwise time travelers and time themselves may be seriously injured." Mr. Thor nodded very seriously and said in an extremely serious tone.

Five hours? That's a fart... Cough, it seems to be very useful, but compared to the effect of the time machine I imagined at the beginning, it was a huge discount, which made people extremely disappointed. Pei Chen was the same. His hot eyes were instantly dimmed, as if he had just a short sentence of his words and he no longer paid too much attention.

Mr. Thor couldn't help but feel anxious, and there was annoyance that he had been looked down upon by others: "Five hours are just basic safe time in theory. In fact, as long as your body can afford it, it is OK to go back to how long time it will be, but that is very dangerous - some wizards tried to travel farther in time, but they were seriously injured. For many years, no one knew why the long-distance time travelers died on the journey. Since 1899, people stopped trying because what happened that year not only killed the time travelers, but also disturbed the time itself..."

"The Ministry of Magic had worked hard to cover up this matter, and since then, the time travel experiment was under the strictest laws. In fact, when you used the time converter, you had violated hundreds of laws. If it were not for the guarantee of President Dumbledore, this matter would not have been reviewed at all."

Pei Chen didn't care about how severe the time travel experiment was controlled by law. After Saul said such a long sentence, he just keenly captured the keywords and sentences: "If the body can bear it... can travel time unlimitedly?"

"In theory, Ms. Elois Mitubao jumped forward for a full five hundred years to cause such a big trouble..." Professor Thor nodded and said proudly, "But this behavior is illegal. The Ministry of Magic prohibits anyone from owning a time converter privately, and almost all time converters are kept in the Department of Mysterious Affairs."

Suddenly, Pei Chen's eyes lit up. At this moment, he was very serious about putting the idea of ​​"attacking the Mysterious Affairs Department" on the agenda. If the normal way could not get such precious props, he would never mind making a fortune before returning.

No matter how you look at this, they are all five-star or above props?

Seeing that Professor Thor seemed to want to continue publishing his long speech, Dumbledore just looked at him with a smile and said coldly: "Everyone, I think we shouldn't be in class time now. Maybe you can consider finding a room to talk long and long, but now we're better off doing what we have to do first."

Pei Chen: "..."

Thor: "…"
