The letters on the light screen slowly re-morph and re-arrange themselves into combinations before displaying a question, "Where does time begin?"

This question was really unusual for Luke, because in the strict sense, time itself actually does not exist, is a more abstract concept, is the movement of matter, the continuity of change, the sequential performance. Time is a parameter used to describe the process of the movement of matter or the occurrence of events defined by mankind itself, to determine the time, is to rely on the law of the change of the cycle of matter without external influence. For example, the cycle of the moon around the earth, the cycle of the earth around the sun, the cycle of the earth's rotation, the cycle of atomic oscillations and so on. Einstein said that time and space are an illusion of perception.

But it was clear that the question wasn't asking Luke to explain it from the physical side, but again, he had to think of a direction to start from that would convince the other side to take a somewhat philosophical angle.

After gathering his thoughts, Luke, who had been exercised by the Ravenclaw Common Room door ring for half a term, had a flash of insight: "Present time ends just now, and future time begins in the present."

It had to be said that it was a curt statement, but the fact that the bronze door should have opened indicated that the other side, as always, agreed with this type of answer.

Behind the gate, the mists filled the air and it was as if Luke saw a void into which he stepped, and soon these mists changed, which left him standing at that moment on one of those vast plains on the surface of the moon that were massively spread out and formed by huge impact craters filled by dark-coloured lava flows of basalt spewing out of volcanoes, and in this area where there wasn't even a single drop of water known as the 'lunar sea' ' The area with not a drop of water was called the 'Moon Sea' looking back at the large blue planet next to it, while multiple stars that didn't belong there were hovering behind it.

Already a little dizzy Luke could not help but be attracted by its beauty and mystery, careful observation of the surroundings for a long time and did not find any danger, he began to try to move on his own, and bowed to try to touch the surface of the moon under his feet, but just as he stretched out his arm, the moon under his feet as a frightened beast like a swiftly flew away, and disappeared again in the mist.

Instantly, all the mists swirled around Luke. Luke was as if he was in the centre of a tornado, the outer layer was surging while the centre was calm. Knowing that this is the illusion magic caused by the scene of Luke calm and composed, quietly watching the change, with the rotation, the outer layer of fog drift away, gradually the inner layer of fog also disappeared layer by layer, presenting Luke in front of the eyes of the vast and boundless stars, as the ceiling of the public lounge enlarged countless times.

An ethereal and serious female voice occupied this space: "Only a wizard of superior intelligence can complete this astronomical puzzle. Please according to your observation angle on the moon just now, from this side of the universe in front of you, find the position of those stars that you have just seen, and restore them control to the position they stayed in just now, ten minutes is the limit, if you pass, you can go to the next level, if you fail, you will be teleported out after casting a powerful forgetfulness spell to make you forget everything."

Wisdom is a kind of advanced comprehensive ability, containing a variety of abilities such as perception, knowledge, memory, understanding, decision and so on, this level examines the ability of memory, observation and decision. And it was true that Luke had constant the ability of overlooking with the help of the university bully system, but this ability did not include graphics! In this kind of rambling stars that had also changed to a top-down perspective zoom, in just ten minutes, just by using the naked eye to try to identify and successfully find it, this was almost an impossible task for the current Luke, to know, he did not make it a habit to drink a plant protein drink that was squeezed with six walnuts every day.

Unauthorized tale usage: if you spot this story on Amazon, report the violation.

Right at this moment, Luke suddenly thought of another item in his storage space, and at this moment, he was incredibly grateful for his good luck in the beginning. The system storage space quickly surfaced in Luke's mind. Luke chose the ancient parchment tied with a red string, the red string automatically fell off, the parchment slowly unfolded, and on it was written, "Scholar's Halo."

Below the parchment was marked with the function: before using it, the time it will be used is clearly declared in advance, within the timeframe covered by the aura, the host can obtain a stronger good luck effect than the blessing potion as well as a magic power increase, and temporarily obtain the wisdom of a powerful sorcerer from antiquity and the accumulated knowledge of three magical libraries.

Without a doubt, Luke immediately chose "Use Aura for three minutes". Luke's mind was instantly filled with the knowledge stored in it, and after a brief tingling and dizziness, Luke regained his clarity and felt the wonderful illusion of being in control of his omniscience and omnipotence.

The extra knowledge in his head put the stars under control, and he searched the endless starry sky, constantly eliminating the interfering stars. The image of the target star in Luke's mind was incomparably clear, and comparing it to these stars, Luke was able to quickly capture every nuance. Instead, it was a bit of a pity that Luke had moved these stars to the correct position in a little over two minutes, and the extra remaining time could only be so wasted.

Although that cool female voice didn't reappear, the spinning and broken stars in front of him invariably indicated that he had passed the test.

"This level of difficulty is obviously not a test for small wizards... No, I should say that even adult wizards who are generally proficient in astrology can't easily pass it, so why did Ravenclaw set up such a difficult level to test others? If you don't happen to have the aura of a schoolmaster to be able to pass it yourself, there's definitely no chance of success, and being cast with an overly powerful Oblivion Spell could potentially cause irreversible magical damage to the brain, and any after-effects of such a magnitude as forgetfulness would only be considered a very mild side effect."

But without waiting for Luke to think more, the cosmic stars in this side of space shattered into countless pieces, spinning and disappearing.

In front of his eyes, these fragments began to slowly morph again, transforming into a mage tower with a strong medieval fantasy style, the door of the tower opened noiselessly in front of Luke, and he obediently stepped in, and a light screen as thin as a cicada's wing was quietly suspended in the air.

There was no content in the light screen at the moment, and through it, one could see the opulent decorations behind it. The tower was of great artistic beauty, decorated in deep blue and bronze colours, and the interior had exquisite ancient style furniture and luxurious carpets, which seemed to be mostly delicate enough to count as enough to be able to be called a work of art.

The ceiling was decorated with silver blue fire dragon scales, Luke judged that it seemed to be from the Swedish short-nosed dragon, the rounded curved crystal chandelier was in the air in the form of a ladder spiral, the top of the surrounding walls were painted with the same events recorded on the tapestry just now, except that the technique seemed to be advanced by a few hundred years, which made Luke feel more and more bizarre, knowing that although it was not possible to clarify to the specific events, according to the records of books related to the history of magic What can be clear is that Lady Rowena Ravenclaw died in the eleventh century.

But it was too late for Luke to think about it, the light screen in front of his eyes was filled with blue light, and the star map of the universe that had just been turned into fragments converged on the light screen again, and a model that was exactly the same as the tower he was in appeared on the lower right side of the light screen. Countless silver lines criss-crossed the star map.

It was the same female voice: "Extend your wand and cast the 'Move' spell to complete the universe travelling game. If the game is completed, you pass the level, otherwise you will be confined inside the tower forever."
