People are in Hogwarts, What the hell is the flood system?

After realizing that his still unmanifested Patronus was likely Pangu, Rhine's heart couldn't help but beat faster.

Looking at the original Harry Potter books, the most powerful Patronus that appeared was Dumbledore's phoenix, which could easily drive away hundreds of Dementors.

But if Rhine's Patronus is really Pangu, even if it's impossible to have the earth-shattering power of the Great God Pangu in the primordial world, its upper limit must be much stronger than the phoenix.

The key is that this prestige is directly maxed out!

Rhine even faintly felt that when his Patronus was truly fully manifested, it might give him a considerable surprise.

Just at this moment, Rhine turned his head to look towards the depths of the restricted area, a hint of surprise and doubt in his eyes.

"Hmm?"

Previously, although Rhine had cleared hundreds of books from the restricted area, the remaining books were still vast and boundless, with no end in sight.

The depths of the restricted area were still filled with various strange magical powers.

But after Rhine's Patronus Azure Lotus emerged, the entire restricted area calmed down, and even the tomes containing powerful magic in the deeper areas seemed to be subdued by Rhine's Patronus, all becoming well-behaved.

But now, in the silence, Rhine vaguely felt a call from the depths of the restricted area.

"Come here..."

The magic contained in this call was extremely ancient.

It reminded Rhine of the giant squid he encountered in the Black Lake, with some similarities between the two.

However, this call only lasted for an instant before stopping abruptly, almost making Rhine wonder if it was a fleeting illusion.

But the message on the system screen would not be wrong.

【Deep in the Demon Cave, you seem to have faintly sensed a fleeting opportunity】

【It should be due to insufficient cultivation; the time for the Source Law has not yet arrived】

Thoughts flashed through Rhine's mind.

"Could it be something related to ancient magic?"

"That's right, the Four Founders must have come into contact with ancient magic at that time. Godric Gryffindor may have become a giant squid and remained at Hogwarts."

"A hundred years ago, ancient magic also appeared briefly at Hogwarts, which shows that ancient magic has always remained at Hogwarts, possibly sealed, and only appears when certain conditions are met."

"My use of the Ancient Staff to cast the Patronus Charm before may be this factor, or it may be my special Patronus that caused some reaction in the sealed ancient magic."

However, after a moment, Rhine calmed down the distracting thoughts in his mind.

If it were someone else, knowing the news of ancient magic might drive them crazy, and they would not hesitate to spend their entire lives on it.

But for Rhine, it would certainly be better to obtain ancient magic, but he wouldn't force it if he couldn't get it.

After all, this thing wouldn't have a great impact on his strength. When it really comes to life-and-death struggles, he still relies on the abilities he obtained from the Primordial System.

At ordinary times, these common spells are enough for Rhine to solve problems.

Therefore, since the system has said that his cultivation is insufficient and the opportunity has not yet arrived, Rhine will not go searching for a needle in a haystack.

Compared to pursuing ancient magic, he is now more interested in another spell.

Rhine's eyes were bright.

"Incendio, Transfiguration, plus the Fire Control Ruyi talent, relying on these, I previously used a knock-off version of Fiendfyre."

"But compared to the real Fiendfyre spell, it still lacks the crucial Patronus Charm, so it only has the form but not the spirit."

"But now, I also know the Patronus Charm, even if it's incomplete, it should also meet the requirements of the genuine Fiendfyre."

Rhine had always been thinking about this spell.

There's no way around it; although its power is certainly not as good as his running his body and using the Staff Divine Ability, it's cool!

Dumbledore using it in the movie was already very cool, and in this real magical world, the scene of Fiendfyre is even more intimidating.

Moreover, if he really gets the Samadhi Fire or other flames in the future, the power of Fiendfyre will also skyrocket. Mastering this spell sooner rather than later is definitely not a loss.

As for now, Rhine's gaze fell on the Reverse Magic Source talent, and he had another idea in his mind.

This talent allows him to use black magic to produce the effect of white magic, so what if he uses it to cast Fiendfyre to replace Incendio?

That power would definitely be further enhanced.

Thinking of this, Rhine revealed a look of anticipation.

Immediately, he left the restricted area and went to the Room of Requirement again.

"First is—accepting the Reverse Magic Source talent."

As Rhine whispered, the words Reverse Magic Source clearly appeared in the reward column.

Rhine immediately felt that once this talent was activated, he seemed to understand the evil aura of demons. Not only could he cast demon magic and supernatural powers, but he could also remove the ferocity within and transform it into upright and magnificent moves, which can be described as using demons to enter the Dao and using demons to overcome demons!

Then, Rhine's eyes revealed a look of curiosity.

"Sectumsempra!"

A Sectumsempra was cast under the operation of the Reverse Magic Source talent.

In the air, it instantly seemed as if an invisible sword energy flew out, upright and magnificent, and indestructible, just like the sword energy emitted by a flying sword cultivator!

Rather than saying it is black magic, it is more like a kind of cutting curse similar to the Bombarda and Incendio, and there is no so-called side effect of distorting the soul.

Rhine revealed a look of surprise.

"The Reverse Magic Source talent is really useful for magic?"

"What about the Unforgivable Curses?"

Rhine's expression was deep, and he waved his wand.

"Imperio!"

The magic that was originally supposed to control the minds of living beings at this moment dissipated the bewitching effect and instead became a fierce mental impact.

"Crucio!"

This curse used to torture people, under the Reverse Magic Source, the effect became countless tiny sword energies penetrating the opponent's body's acupoints.

With a single thought, it can cause the opponent's acupoints to collapse and the meridians to be completely shattered, but if there is goodwill in the heart, it can also dredge the acupoints, activate the qi and blood, and even have the effect of helping to increase cultivation.

As for Avada Kedavra, the eerie green light turned into a deep black light, filled with the meaning of annihilation.

Under the flight of the black light, everything hit was turned into dust!

Rhine fiddled with the Unforgivable Curses for a while, revealing a look of joy.

The power after the reversal of these Unforgivable Curses, especially the reversal of Avada Kedavra, even if he has attained the Vajra Body without confusion, I'm afraid it would not be easy to bear after being hit.

In this way, there are several more powerful means.

Using it when needed, I believe no one will recognize that this is an Unforgivable Curse, which can save a lot of trouble.

Then, Rhine's eyes showed a strange color, and he cast the Fiendfyre Curse.

The original black Fiendfyre has now turned into a golden-red flame, eternally unextinguished, emitting a strong sense of holiness.

All evil seems to be burned to ashes in front of it.

Rhine recognized this flame.

This is Gubreathian Fire, the Eternal Fire.

It is completely opposite to the vicious Fiendfyre and is the most sacred flame.

In the original book, only a few wizards were able to cast this flame, and only Dumbledore had truly used it.

Dumbledore's Fiendfyre is suspected of using not ordinary Incendio, but this Gubreathian Fire!

Rhine took a deep breath.

"The last piece of the puzzle is also collected."

"Then, use this to cast Fiendfyre?"

In the next moment, accompanied by the Fire Control Ruyi talent.

The raging Gubreathian Fire condensed into a ball.

The Thirty-Sixth Grade Lotus was also floating and sinking in the silver light, shining with the Gubreathian Fire.

Then, a golden path of flames instantly spread forward!

I caught a cold after taking the train, and I suspect I was infected with a virus. My condition is very bad. Today's update is a bit late. There will be at least two more updates later, and I will finish writing them before twelve o'clock. Sorry.
