Divination is a very profound science, the threshold for mastering is casual, the sub-disciplines are complex, and it is easy to understand and difficult to master.

Divination is not something that can be learned by any wizard, and those who are not gifted can only make a living in divination classes.

Hogwarts didn't originally plan to train all of its students to become soothsayers, and setting up a divination class was just casting a wide net.

Except for Parvati Petyr of the Lion Academy, none of Zhang Xu's classmates had discovered a talent for divination in the divination class, not even her twin sister Padma Petyer. In addition, Zhang Xu, who did not choose a course and mainly relied on spoilers for divination, is only one and a half wizards with divination talent among the students in this year's class.

There are many sub-disciplines of divination. In terms of direction, from the general trend of the world, natural disasters to clothing, food, housing, transportation, and the marriage between two people, different soothsayers are good at divination in different directions. In terms of means, Hogwarts alone has taught tea, dream interpretation, smoke, astrology, and so on.

The combination of direction and means makes the resulting figures terrifying.

Every soothsayer has a specialization, and the study of a soothsayer is actually to find out what his specialization is.

At the beginning, Zhang Xu asked the house-elves in the kitchen to help him keep the beef blades, and after tossing and turning and finding that he had no talent in this area, the remaining beef blades finally went into the soup pot.

The most important thing in divination is to [REDACTED]flicker[/REDACTED] interpretation, and when the soothsayer sees a foresign from the future, how to interpret it becomes a very challenging place.

Those who engage in divination generally do not say enough words, and always leave some leeway for themselves. How to prevent customers from giving bad reviews afterwards is a great test of the soothsayer's literary skills.

For example, Zhang often complained about Zhao's "five stars out of the east to benefit China", and the scholars at that time generally believed that the five planets of water, fire, wood, metal, and earth gathered in the eastern sky. As a result, on the day of the founding ceremony, a group of people dropped their jaws in shock.

After returning from the centaur tribe, Zhang Xu has been thinking about this prophecy given to him by the centaur elders, so much so that Umbridge appeared in the professor's chair at dinner, and Luna kept rubbing his hands with her fingers without paying attention, just mechanically stuffing food into her mouth.

If Centaur hadn't read the full Harry Potter works, then his prediction would have shocked Zhang Xu too much.

It was not surprising that the centaur elder had predicted the upcoming wizarding war, and if he hadn't learned a little bit of real talent, he wouldn't have been able to become an elder in the centaur tribe, which was famous for astrological divination.

What made Zhang Xu puzzled was the planet that appeared fifteen years ago and hid behind Mars four years ago.

In Zhang Xu's opinion, the appearance and movement of this planet look familiar to him, as if he can match his own number.

Fifteen years ago, the planet appeared, just when he came to this world.

Four years ago, the planet orbited behind Mars, coinciding with the time he came to Hogwarts.

Since then, the spark representing the war has become brighter and brighter, and he has been preparing for the final battle with Voldemort since then.

It is not surprising that the astrology can predict the future, the question is what is going on with this new planet, and he does not think that he can affect the movement of celestial bodies in the universe.

After dinner, Zhang Xu went to the office of Aurora Sinista, a professor of astronomy, to find an expert to find out about the planet.

As a result, Professor Sinista was not in the office, and Zhang Xu climbed to the top of the Astronomical Tower.

At the top of the tower, Professor Sinista observes the sky with an astronomical telescope and then makes notes on parchment.

Zhang Xu waited quietly for more than an hour, and did not go up to say hello until Professor Sinista put away the parchment.

"Good evening, Professor Sinista."

"Good evening, Zhang." Professor Sinista responded, "Sorry to keep you waiting. ”

"It's okay," Zhang Xu said, "I have a question about planets. ”

"No problem, come to my office." Professor Sinista said.

Presumably to facilitate Professor Sinista's work, the top of the tower is the office of the professor of astronomy.

The two sat down on the couch, with two cups of Professor Sinista freshly brewed coffee on the coffee table.

"Professor Sinista, I recently received a prophecy from the centaurs that a planet suddenly appeared in the starry sky fifteen years ago, and four years ago this planet orbited behind Mars, do you have any records of this planet?" Zhang Xu asked.

Professor Sinista listened to Zhang Xu's question, thought for a while, and said, "You are asking about that 'naughty ghost'." ”

"Naughty?" Zhang Xu asked curiously.

"Yes." Professor Sinista went into lecture mode, "Fifteen years ago, wizards and centaurs who watched the stars discovered it. ”

"It's just that it's naughty, and at first it was very fast and the star was bright, so everyone thought it was a meteor at the time."

"But in the next few days, it reappeared."

"Because of the short time it appears each time, it was once thought that it was a new satellite of the Earth. But if the Earth has new moons, then it is impossible not to have no signs before the new asteroids fly to the Earth, which can be seen. ”

In the days that followed, new discoveries were made about its observations, and its brightness was not fixed. Sometimes it's darker, sometimes it's a little brighter. ”

"During that time, 80 percent of the articles in Starfield magazine were about it. Later, I don't remember who gave it the nickname 'Naughty Ghost' in the article, and since then everyone has called it 'Naughty Ghost'. ”

"At that time, I had to receive a lot of letters from other stargazing friends every day, and reading letters, replying to letters, discussing and arguing in letters took up most of my time."

"Did you conclude anything about 'Naughty Guys'?" Zhang Xu asked.

"Nope." "Then we found out that there would be a slight change in its orbit, which got us talking about it for a long time. ”

"And because it's so fast, it only takes about a second to appear in the telescope, and no wizard has been able to see it clearly for so many years."

"Later, everyone's enthusiasm for studying it gradually decreased, and only me and a few friends were left on the wizard's side to pay attention to it from time to time."

"So it went behind Mars four years ago and hasn't been seen since?" Zhang Xu asked again.

"It's not going behind Mars, it's going to stop reflecting the sun's rays on Earth when it flies in front of Mars." Professor Sinista said as he took a sip of the rest of the coffee in his cup.

Zhang Xu had a question mark on his head, waiting for Professor Sinista's explanation.

"Zhang, if you hadn't come to Hogwarts, then we would never have known the true face of the 'Naughty Man'." Professor Sinista said with a sigh.

Zhang Xu thought for a while, and a guess suddenly appeared in his heart that made him shout "lying on the grass".

Professor Sinista continued: "Shortly before it finally appeared, I assumed it would fly near Mars, so I spent the night staring at Mars in front of a telescope, hoping to wait for it. ”

"Then I succeeded, and in less than a second I saw it and drew it."

Professor Sinista used a flying charm to summon a parchment picture book from the bookshelf in her office, which contained her own drawings of various planets and nebulae.

Professor Sinista opened one of the back pages and pushed it in front of Zhang Xu.

Zhang Xu saw the shape drawn with a few strokes on the parchment, and blurted out the sentence "[Prohibited Matters]".

Fortunately, Professor Sinista did not understand Chinese, otherwise Zhang Xu would have been deducted points for swearing.

From the outline on the parchment, it can be seen that this new planet that has puzzled wizards for years is the Mir space station launched by the red woolly bear.
