In the previous chapter, the characters of the three series of "Dragon Killer", "Dark Elves" and "The Lord of the Rings" were randomly entered, in fact, I originally wanted to write the Leylins of "Dragon Lance" and Illidan and Quel'thas of the World of Warcraft, but considering that these are all unnatural deaths, they were excluded by Vivien.

Having said that, in fact, this chapter can be renamed "Hogwarts Underground Labyrinth Quick Guide", no one wants to complain?

===================================

7 of Cups (Reversed): Approaching the goal achieved.

、

Hogwarts, England

、

Although Opal was ready to fight a long battle, she was a little surprised that the Gryffindor team of three was probably troubled by the upcoming exams, and for a long time they were in a monotonous state of classroom-library-classroom-lounge-classroom.

Well, it can't be ruled out that he was frightened by the dragon incident in the Forbidden Forest, so he decided to be a good student for a while, and by the way, he could make up for the hourglass of the academy that had been emptied a lot because of their involvement.

Merely...... Either piece of news is good for Opal.

If it weren't for the vague "plot" relationship and the intuition that this kind of thing would definitely happen, Opal really didn't know if he would be able to continue with this boring stalking.

Thankfully, the days weren't short, but they weren't long, and a few days after the exams, just as Opal was about to get impatient from waiting and was looking for an opportunity to reach out to Harry, things finally started to take a turn for a pity.

[Should I say they're finally acting?] ]

After being woken up by Nagini in the middle of the night, although he was a little resentful of when the Gryffindor trio was not good at choosing the third watch in the middle of the night, but looking at the three orange-red dots displayed on the map of the dragonskin living spots moving rapidly, Opal finally breathed a sigh of relief, took the uplifting potion placed on the side of the bed and took a sip.

{Miss Opal.} }

Coiled over the bedpost, Nagini swam to her side a little uneasy, {Are you going to go alone?} }

[Am I that mindless?] ]

After changing into Vivien's suit, Opal fastened the bag containing the potions and emergency supplies to the belt buckle at her waist, and then reached out to Nagini. ]

Although Opal believed that with her strength, there would be no place in the entire Hogwarts or even the Forbidden Forest that she could not go alone, but after all, this operation was very important, so Opal felt that she had to be fully prepared no matter what.

And the Nagini that Riddle gave her can come in handy in many things, and she naturally wants to carry it.

{Okay.} }

Nagini wrapped his wrist around Opal's wrist and shrunk it to the size of a bracelet, while Opal drank the invisibility potion he had prepared, picked up the map and walked out of the room.

、

Following the instructions on the map of the living spots, Opal made his way to the third floor staircase, where the door was already ajar.

Upon entering, Opal saw a man who was snorting and gasping for breath at the door on the floor, and said, "Mr. Louwe? ]

[Your Highness?] ]

After sniffing the air, the three-headed giant dog blinked in confusion, [Why are you here?] It's late! ]

[It was your master who asked me to come and check on the situation.] ]

Opal took a handkerchief from his clothes and put it under the three-headed dog's nose, [You can tell what it tastes like, right?] He said you could tell if it wasn't his. ]

Of course, this handkerchief was not given to Opal by Hagrid, the owner of the three-headed dog.

In fact, Opal gave her permission through Vivien, checked the records of dangerous animals registered on the Hogwarts roster, and confirmed that the owner of the three-headed dog called "Louwe" was Hagrid, and found a way to ask those friends in the forest who like to collect things to find it from Hagrid's cabin.

Anyway, the last Norwegian Ridgeback incident made Hagrid's cabin a mess, and I believe that even if a handkerchief was missing, Hagrid's thick nerves would only think that he had accidentally lost it and would not care.

Moreover, Hagrid couldn't understand Lu Wei's words, and the three-headed dog's magic resistance was also very high, and the Dementor's mind couldn't work at all. So Opal doesn't have to worry about his little trick going through the trick at all.

[I haven't heard the master mention it, but it's really the owner's thing.] ]

Sniffing the handkerchief, Lu Wei, who didn't think that the "Son of Gaia" would deceive it at all, shook his tail and let go, [Just jump down, and please be more careful, Your Highness.] ]

[I'll take note.] ]

After gently scratching Louwe's chin in gratitude, Opal turned and lifted the floor door—there were only a few short steps below the door that served as a cushion, and then it broke like that—and below was a hole in the ground that seemed to be heart-wrenching with "bottomless depth".

After glancing at the dark cavern, Opal jumped without hesitation.

Wet and cold air blew up from underneath his body, and after a not-so-short fall from a great altitude, Opal landed on top of something soft with a strange sound.

[Your Highness?!] ]

Just as Opal curiously touched something underneath her, subtle fluctuations came into her mind, [How could you fall from it without any protection at all!] What a carelessness. ]

[Sorry to worry you.] ]

Immediately judging that it was the devil's net that liked darkness and dampness, Opal gently patted the plant under him that was shaking because of excitement or for some reason, [Can you put me down?] ]

[Our pleasure.] ]

The extended rattan gently curled Opal's body, and then slowly moved her to the ground on the side, [You didn't get hurt when you fell from that height, did you?] ]

[Totally fine.] ]

Smiling and patting the rattan netted against her, Opal said softly, [There is no magic element here that you need, and it is too noisy...... When I get back, I'll suggest Professor Sprout help you change your environment. ]

[That's great, knowing that the four-legged hairy creature above keeps making noises that keep us from growing quietly, and even the new rattans have withered a lot!] ]

The devil's net rubbed on Opal's body affectionately, [It's better Your Highness, those three two-legged creatures just now are light and fire, so annoying...... People are just curious about why they are hot. You see, the beautiful leaves that people have grown with great difficulty have been scorched! ]

[No way, after all, they don't know your personality very well, probably thinking you want to eat them.] ]

After soothing the muttering and complaining net, Opal smiled bitterly in his heart - I believe that Harry's group did not know that this devil's net that grew up at Hogwarts was vegetarian with an ample supply of mana, but it was more playful, and he liked to roll it up when he caught something hot and didn't shine.

[Even then, you can't do this to others!] ]

The devil's net, who obviously felt that he was very wronged, rubbed Opal again, [Ah, by the way, Your Highness, take a few leaves from other people's houses.] It's not clear what else is behind, but people's leaves should be useful. ]

[Well, then give me a few leaves that you replaced.] New leaves are not needed. ]

[Your Highness is really very considerate!] ]

After receiving the blades from the Devil's Net, Opal continued along the only passage, where the ticking of water could be heard running down the wall, and a short walk was a short walk downhill.

As he reached the end of the hallway, Opal caught a soft, "rustling" sound behind the door, as if coming from above.

Entering the room, the high-arched room was noticeably brighter than the darkness of the hallway, filled with small birds that glowed like jewels, flapping their wings and flying.

On the other side of the hallway was a thick, solid wooden door.

Although I can fly, yes...... But that's too much, isn't it?

After looking at the keyhole on the wooden door, confirming that the "Solid Spell" and "Anti-Spell Barrier" had been applied to it, and that it could not be broken by brute force, and then looking at the group of winged keys above his head, Opal pressed his forehead a little weakly.

[That, I say...... Can we discuss a thing? ]

Raising his head, Opal let his magic shine through.

There was a slight pause in the sound of flapping wings, and then there was the sound of Suosuo's landing.

[Are you going to the wooden door too?] Your Highness. ]

Apparently in the form of a leader, a silver key with wings fell in front of Opal, but the feathers on its wings were disheveled, as if it had been brutally grabbed by someone.

[Pathetic.] Are you okay? ]

Reaching out to gently straighten the feathers on its wings, Opal took out a small vial of rejuvenating potion and put a few drops on it.

Perhaps because of her status as the "Son of Gaia", Opal felt that she could be more patient and attentive to these non-human magical creatures as long as they were not hostile - and she did not reject this feeling.

[Your Highness is really kind...... It's not at all like that group of bastards. ]

The silver key stopped in Opal's hand, [I'm the key to open that door, use me.] ]

[But in that case, your feathers won't ...... again]

[As long as you don't hold my wings, it's okay.] ]

[Thank you very much.] ]

[Where, I'm glad to be able to help His Highness so gently!] If I run into those rude bastards from before, you must help me scold them! ]

[I'll try my best to do this.] ]

Opal sweated profusely on her head - God knows, she was taught to be completely absent from "swearing" when she was a child.

The wooden door was opened with a silver key, and the room behind it was dark at first, but when Opal stepped inside, the room was immediately filled with light, and Opal found himself standing on the edge of a large chessboard, with black chess pieces in front of her, each of whom was taller than her, and a white chess piece guarding the other door.

This ...... Do you want her to play chess?

Scratching his hair, Opal looked at the chessboard with some embarrassment - although he could tell that this was a wizard chess that had been more popular among his classmates recently, but ...... She doesn't even know the rules of wizard chess, so she can't play!

Just as he was thinking about whether to use the time return device, Opal's eyes fell on the majestic black king on the chessboard, and he was embarrassed for a moment.

What's that, the one on the shoulders of the black net...... Unknown creatures, it seems...... It's Ron, right?

After confirming the matter with the black line on his head, Opal thought of another way, so he walked to the edge of the chessboard and gently touched the black king's clothes.

[Well, can I have a discussion?] ]

Opal smiled at the Black King, who had already lowered his head to look at her, at least a body taller than himself, and smiled, [The person on your shoulder, can you lend me for a while?] ]

[……]

There seemed to be silence for a moment, and the Black King readily put Ron down, acquiescing to Opal's request.

A bottle of invigorating potion brought Ron back from his stupor, and before he could react, an Imperio took control of his consciousness and then demanded that Ron win a game of wizarding chess under his command.

Although he was not sane, Ron did the job well.

After the victory, Opal politely thanked Ron, and a "Obliviate" erased his memory.

To be on the safe side, Opal also added a "Stupefy" to him, making sure he could sleep for another two or three hours without interfering with her movements. (Tianyin: It's a typical bridge crossing the river, Opal...... ）

After thanking the Black King again, Opal was about to open the door behind the chessboard when he heard hurried footsteps from inside—as if someone was running out of it.

After giving himself an invisibility charm, Opal Shi rushed out Hermione and passed by and entered the room inside.

If it was Hermione, she should have gone to ask for help, right? It seems that the time she has to use is running out......

After weighing it for a moment, Opal sped through the room with the unconscious cave giant, and entered the next room, then looked at the seven bottles of different shapes on the shelves in the room, and then at the flames that had been lit in front of the door, and the note on the shelf, Opal pressed her temple a little weakly—she began to have a headache.

"There is danger in front of you, and there is safety in the back, and if you find it, two of us can help you, one of the seven will help you on, the other will send you back to where you are, and two of them are just ordinary Zun Ma wine, and three of them are deadly poisoned wine.

If you don't want to stay here forever, go for it!

To help you choose, we have four tips: first, no matter how secret the poisoned wine is, you can always find it on the left side of the nettle; Second, it's always a different wine that stands on the edge, but if you keep moving inward, there's no good wine; Thirdly, as you can see, all bottles of different sizes, short or tall, are not dangerous; Fourth, the second on the left and the second on the right are actually a pair, although they don't look like each other. ”

[Should I say so?] ]

Looking at the words left on the note on the table, Opal muttered softly, [What a Slytherin bad taste!] ]

Although the potions in this room were magically replenished, it seemed that it would take time to replenish the potions, and the only potions that could be used had already been drunk, so there were only two things she could do now - one was to stay here and wait for Hermione to find the rescue, and the other was to reconfigure the fireproof potion that could pass through the flames before the rescue arrived.

Although it seems that there are two paths, her choice is almost fixed.

With a sigh, Opal carefully opened the remaining five bottles and sniffed them inside—almost immediately. A thin black line was drawn over her head.

Professor Snape was a Slytherin through and through, and would want to use this method......

After removing the empty bottle on the other side, and finding that there were still traces of the potion in it, Opal carefully extracted the liquid from it with extraction.

Next, using the residual liquid of the bottle of medicine that can be left as a catalyst, the two bottles of poisonous wine that are highly poisonous but indeed mutually reinforcing in essence are mixed together, and then the leaves obtained from the devil's net before are broken and added to it, carefully warmed with magic flames, and finally added another bottle of poisonous wine about one-third of the amount, and then cooled down with nettle wine.

Once the potion has cooled, it can be configured with a potion of black flames.

Drinking the potion in one gulp, Opal endured the discomfort of the potion starting to work, and continued to the next room.

I don't know how many levels are set up here, but this is said to be to defend against foreign enemies, but in fact there is no danger at all, which makes people feel like they are playing the so-called "trial" level of an RPG game......

If it was really to protect the so-called "Philosopher's Stone", wouldn't it be better to put that thing with Fawkes?

Strictly speaking, this kind of level setting is simply a waste of human time, so what's the point?

As she opened the next door, Opal paused to reminisce about the levels she had experienced, and a little doubt came over her, but she then threw her aside.

If you don't understand, forget it, it's the most important thing to catch up with Harry as soon as possible now, and put the rest aside for the time being.
