Before Professor McGonagall could respond, the character in the other portrait mocked.

"Hmph! Ansel! You Slytherins are just the dark magicians! Voldemort is like this, you old guy won't do much better if I want to see you!" Oliver countered.

"Haha~Oliver! You are just jealous of the excellence of our Slytherins!"

Ansel, who was also a certain principal in the history of Hogwarts, was born in Slytherin, and was a natural enemy of Gryffindor, who was born in Oliver, and they had many quarrels in the past.

This time, the two had just argued a few times, and just when Professor McGonagall couldn't help but want to leave first, the woman in the other portrait stepped forward to smooth things over:

"Okay, okay, what about you two little guys? How many years have you been arguing about this? Are you too tired to panic?"

The old woman's identity is not simple. She is one of the few female principals in the history of Hogwarts. In terms of strength, she can even enter the top ten.

And if we look at the era of his tenure, it is a century earlier than Oliver and Ansel.

"Minerva, why don't you go back and get busy with school work first? With Albus's strength, even though he hasn't practiced divination much, he can still vaguely sense cause and effect..."

"Cause and effect?"

The old woman's words aroused Professor McGonagall's interest. The so-called cause and effect is something more advanced than divination.

Decades ago, Professor Sybill Trelawney accidentally entered that special state, sensed a certain causal line, and therefore made a far-reaching causal prophecy.

It is this prophecy that creates the tragedy of Harry Potter's family.

Cause and effect is a very mysterious thing.

Some people have speculated whether Harry Potter is the prophesied savior?

Was it because he was the savior that the prophecy appeared?

Or was it the emergence of that prophecy that created Harry as the savior?

Moreover, what is even more amazing is that besides Harry Potter, there is another child who meets the conditions in the prophecy.

"Not every prediction is related to cause and effect, but every prediction related to cause and effect will definitely come true, and there is absolutely no possibility of change!"

The old woman's eyes became a little deeper and she said slowly: "The use of cause and effect is not just in the field of prophecy. The so-called whim has actually vaguely touched cause and effect."

Professor McGonagall nodded thoughtfully. Her cultivation level was not low, but she had not touched this field.

The two chatted about spiritual matters, and some old principals on the wall also joined in the conversation.

Unknowingly, Professor McGonagall had listened to a lot of content, and even vaguely felt that his cultivation had become somewhat loose, and actually increased!

Suddenly, there was a rapid knocking sound on the glass, interrupting everyone's conversation. Not only Professor McGonagall, but also the other old principals also felt a little unfinished - they were the former principals after all, and they were the same as those outside.

The paintings on campus are different. Whether it is to maintain one's identity or for other reasons, it is rare to have such a happy conversation on weekdays.

Although it is just a trace of the soul mark in the painting, in many aspects, it is no different from the real person.

Professor McGonagall quickly came to the next room. On the wall behind him, several old principals in the original painting seemed to be curious about who interrupted their conversation. They also left their paintings and entered the room next door.

In the painting of the room.

Although it was a bit funny to see the old headmasters crowded into a few small picture frames, Professor McGonagall's attention was already attracted by the speaker outside the window——

An owl with mixed brown and gray feathers was tapping the glass frantically and rapidly with its pointed beak.

Seeing the appearance of Professor McGonagall, the owl became even crazier. Although it stopped tapping on the glass, it still flapped its wings in mid-air.

"Hmm? Owl? Is this a letter to Dumbledore?"
