Harry potter galactic empire

The recurrence spell is the first tool spell they learned in the magic lock course this semester. It is a special type of magic that specifically targets the traces left by magic in objects or spaces:

It can reproduce the original details and structure of the spell to a certain extent through the magic traces left behind, or in other words, the situation in which the spell was cast by the caster who left the corresponding magic traces. Any spell cast will definitely leave traces, even if

No matter how extraordinary the wizard is, he is no exception, and even if he uses magic to remove it, he cannot completely cover it up.

It's just a matter of how much.

The more powerful the reappearance spell, the more details it can restore, while the more obscure the magic traces, the fewer details it can restore.

For example, the barrier spell left by Xicklea is still very effective, which means that the traces of magic here are intact before it expires.

"The spell returns!" Lin Mo waved his wand, and a light blue light emitted from the tip of the wand.

The light flew forward. It did not turn into shattered sparks like the [Remove Obstacle] just now. Instead, it dispersed into the entire door frame like a soft stream of water, flowing in the space. After a while, the water stream gathered into points from all directions again, and synthesized.

A sparkling particle of light began to vibrate gently in the air, revealing the trajectory traced by the tip of the wand that cast the spell.

At the same time, Sicklea's vague voice was reawakened, as if it was an echo from the time that had just passed:

"There are many obstacles..."

Syllables, rhythms, spelling trajectories, changes and pauses that are not part of standard spells...

Lin Mo identified it carefully.

One of the reasons why Magic Locks is a major course is to teach students how to find traces of magic and identify the corresponding magical structures from vague traces. This ability is used in many branches, such as tracking, archeology, defense, etc.

However, this ability requires long-term accumulation and practice.

It is said that experienced wizards like Dumbledore can even detect traces of magic and deduce the original spell structure through direct observation and perception with the naked eye, while novices like Lin Mo can only use the recurrence spell over and over again.

Observe the concrete casting trajectories and spells repeatedly, hoping to find a clue from the subtle changes.

This is quite time and energy consuming work.

In addition to comparing the differences between the "Many Obstacles" embodied by the recurrence spell and the standard spell over and over again, from beginning to end, he must also make corresponding changes to the "Removal of Obstacles" in response to these differences. This involves

A lot of derivation and even speculation require a lot of time to try and revise repeatedly.

Just like grinding out a matching key according to the keyhole, grinding out a key to unlock a magic lock is also a delicate job.

And what Lin Mo lacks most now is time. It's already past three in the morning, and at least two hours have passed since Hermione sent Harry through the final hurdle. He doesn't know what Scikleya wants to do by locking him here.

, how many chances does Harry have?

But this is the only way for him to get out of here.

After calming down, he forced himself to start researching.

Although he had little hope for this, in the practical examination, just three pauses at the node stumped almost all the students, and for a magic lock, it was as simple as a dented key.

In other words, as long as it is a slightly complicated magic lock, it is very likely that he will not be able to unlock it in his lifetime at his current level.

But to Lin Mo's surprise, when he used the recurrence spell for the fifth time, he felt an unusual sense of familiarity from the traces.

When he used the recurrence spell for the eighth time to observe the traces of magic, the strange feeling of familiarity became even stronger.

It seems...the magic lock that Shikleya left in the obstacle spell seems to be very standard...

It seems that he has seen it somewhere...

He spent two more times comparing the reproduced spelling points with the standard spells from beginning to end. Finally, if he admitted correctly, the magic lock left by Shikleya in the obstacle spell was actually her class.

The example mentioned.

That magic lock, which was not complicated but had an extremely exquisite structure, was the one they had been studying for two weeks in class.

Its several changing nodes of the spell echo each other and fit together in a very special rhythm. If you crack it separately according to individual nodes, you will never be able to succeed.

There is only one most ingenious way to unravel it.

At least that's what Shikrea said in class, and Lin Mo also agreed very much, because if Shikrea hadn't explained it in class, he felt that he would never be able to come up with that kind of cracking method in his life. Even Hermione

They all thought so. Hermione exclaimed in disbelief when Sciclerea explained this magic lock and how to unlock it.

If we really want to use an analogy, we can say that it is a bit like a seemingly simple but well-constructed geometric proof. It can only be unlocked through the most unique and ingenious key, and there is no other way.

But the problem is...he has already learned it...

Like all first-year students, he knew the standard solution to this delicate magic lock.

Why did Scikleia use such a magic lock in the obstacle spell that she explained repeatedly in class, a lock for which Lin Mo already had the key to the solution? It could even be said to be the only lock that he knew the solution to?

Could it be that she got used to it because she had been demonstrated so many times in class?

Or maybe she subconsciously thought that Lin Mo couldn't have come into contact with the third-grade obstacle spell and the corresponding solution, so she didn't pay attention to the magic lock in the spell? She just did it casually?

But then why bother adding a magic lock to the barrier spell?

Is it really because it’s easy?

Lin Mo suppressed his doubts and began to practice solving the curse. After all, he had never tried to integrate the solution of this kind of magic lock into the solution of the obstacle curse. Although in theory, he only needed to match the key to the solution of the curse, in practice,

The application is not that simple. He must complete each movement change in one go and with extreme precision when casting the spell to ensure that the spell and the key take effect at the same time.

This means that standard spell-casting actions and habits must be changed.

When people are nervous, it's easy to misjudge time, whether it's faster or slower. Lin Mo didn't have any timing tools in his hand or in the room. Even the peculiar three-layer hourglass was taken away by Xikelea.

I don’t know how long it took me to successfully cast the changed curse.

"Remove the obstacle!" Lin Mo finally raised his wand towards the entrance again.

The spell hit the invisible barrier, as if a spark fell on the flammable rice paper and suddenly ignited into flames.

He waited patiently until the fire gradually burned out around him, then stepped forward to test it out.

The obstacle spell has been lifted.

finally!

Without bothering to track down Sicklea's traces (such as asking the portraits in the surrounding corridors), Lin Mo ran back to the fourth floor in the dark corridor as fast as he could.

"Jane?!" he said urgently to the empty platform: "Are you still there?!"
