After leading Harry, Hermione and Ron away, Fana and Ender finally entered the bathroom.

According to the plot in her memory, Fana came to the sink in the bathroom and turned on the faucets one by one until she came to a faucet that was not flowing water. She stopped and tilted her head slightly to look next to the copper faucet.

Sure enough, there was a small snake carving next to the faucet.

“This is it!”

Fana took a few steps back, turned to look at Ander, and signaled that it was his turn to take action.

Just as Ender was about to open the entrance to the secret room, an illusory girl's head suddenly popped out from the door of the innermost compartment. It was the ghost that lived in this bathroom, Moaning Myrtle.

"What are you doing?"

Myrtle's translucent face was full of curiosity.

Ander paused, glanced at her face and said seriously: "I will avenge you."

Myrtle was slightly startled, then Ender took out his wand and waved it at her.

Instantly, a cold magical power surged into Myrtle's body, instantly taking away control of her body.

Feeling the invisible restraint brought by magic, Myrtle couldn't help but scream in panic.

"What did you do to me?"

"Nothing, I just hope you can be quiet for a while."

Ender answered calmly, then waved his wand gently, making Myrtle shut up and go into the toilet cubicle obediently.

"I'm sorry."

Ender apologized, then looked at the faucet with the snake carving on it.

Parseltongue is both a talent and an ability, but it is also a language that can be learned and imitated.

A typical example of the former is Harry Potter, who actually doesn't know Parseltongue, but only has the ability to speak Parseltongue because of the fragments of Voldemort's soul, and most of the time he can only use it when talking to snakes.

As for the latter, strictly speaking it is not Parseltongue, but Snake Language.

Rowling used two words to represent Parseltongue and Snake Language, indicating that the two are not completely equivalent.

The typical representatives of Parseltongue are Dumbledore and Ron Weasley.

Dumbledore not only knew Parseltongue, but also Goblin and Mermaid. Ron did not have such a strong talent for languages. He just imitated Harry Potter's Parseltongue in the original book and opened the Chamber of Secrets and Slytherin's locket.

From this point of view, simply imitating Parseltongue can also open the secret room.

As Ander made a hissing sound, the copper faucet immediately emitted a dazzling white light, and then began to rotate rapidly, and the entire pool began to move with it.

Soon, the pool that originally stood there disappeared, replaced by a dark pipe.

"The Slytherin Chamber is down here!"

Ander turned to look at Fana: "Who goes first?"

Fana didn't answer, but cast an armor protection spell on herself and jumped in without hesitation.

Seeing this, Ender's mouth twitched, and he shook his head and said, "I told you a long time ago that you should go to Gryffindor..."

After complaining, Ander followed closely behind, jumping into the dark hole in front of him with his own suitcase.

As he slid down this dark and sticky slide, Ander finally understood why Fana had cast a spell on him.

After sliding along the winding pipeline for a long time, the originally steep pipeline finally became level.

Ender knew that the end was ahead, so he cast a levitation spell on himself before flying out of the pipe.

As he slid out of the pipe, a soft little hand grabbed his collar and stopped Ander in mid-air like holding a hydrogen balloon, preventing him from crashing into the slippery and dirty wall.

"Clean it up!"

Ender landed smoothly and immediately waved his wand to clean the dirt off his body.

"Lumos!"

Fana raised her glowing wand.

With the help of magic light, Ander could see the surrounding environment clearly - it was a dark stone tunnel with a very wide interior. The ground was full of stagnant water and silt, as well as many animal bones.

Great, found the place!

Ander nodded, then looked at Fana.

She was wearing magic contact lenses that sparkled with stars, and had sunglasses and an eye mask on her forehead. In her arms, she was holding a rooster with a blood-red comb, and two loud speakers that recorded the rooster's crowing in the morning.

There is no doubt that these things were prepared by her in advance to deal with the basilisk.

Looking at the big rooster in Fana's arms, Ander couldn't help asking, "Where's your owl?"

Fana looked down at the rooster in her arms: "It's right here!"

Ender was surprised and asked, "You used the Transfiguration Charm to turn it into a rooster. Will it work?"

Fana smiled slightly: "On the contrary, I used a Transfiguration spell to turn it into an owl."

Ander suddenly realized, "So, you've been preparing since the beginning of the school year, right?"

Fana smiled, looked at the animal bones around her and said softly, "The next stage is yours!"

Ender nodded calmly, took out his wand and waved it gently.

In an instant, cold magical power surged into the corpses on the ground.

All the corpses, whether broken or not, stood up with a creaking sound.

This is Ender’s exclusive spell [Resurrection of Corpses]!

Resurrection of the corpse is not the reappearance of the corpse. It is a necromancy spell developed by Ander based on his own magical properties, which can give the dead corpse a certain degree of mobility.

Then Ender used a clearing spell to clear a space, put his suitcase on the ground, and opened the lid.

As the dead man's hand, which had turned white from being soaked in the lake water, grasped the edge of the suitcase, a hideous-looking corpse crawled out of the suitcase.

Fana subconsciously took a step back, and a hint of surprise flashed in her eyes as she looked at the corpse.

This was the first time she saw Ander use such evil black magic...

But for some reason, she didn't feel scared even though she was surrounded by skeletons and undead.

As the first Inferi crawled out of the suitcase, one Inferi after another crawled out of the suitcase continuously.

Gradually, the originally spacious dark tunnel was filled with these constantly pouring out corpses.

Wherever Fana looked, she saw pale, hideous and ugly faces.

Ander glanced at Fana and continued to summon the Inferi, explaining softly, "I brought these Inferi out of the cave in Half-Blood Prince..."

"I see."

Fana nodded, then looked at the suitcase with Inferi still crawling out of it and couldn't help asking, "How many Inferi do you have?"

Ander thought for a moment and said, "About seven or eight hundred. If you include the animal corpses, there should be over a thousand!"

Fana couldn't help but be a little surprised: "So many?"

Ander shook his head. "No matter how many cannon fodders there are, they are just cannon fodders. At most, they can only distract the enemy and cannot form real combat power. If you want to kill the basilisk, you still have to rely on your rooster and my corpse poison..."

Fana asked doubtfully: "Corpse poison?"

Ander nodded. "Well, I extracted toxins from the corpse, and after mixing them with my magic, they became corpse poison. All lives infected by the corpse poison, as long as they are not cleared in time, will gradually turn into my corpse. I have already thought about it. If your rooster's cry can really kill the basilisk, that would be the best. If it can't kill it, then I will rely on my corpse poison to slowly grind it to death!"

As the two were talking and summoning Ender's army of undead, another figure appeared in the bathroom.

Lin Zhongtian looked at the dark pipes that appeared on the bathroom floor, and a look of surprise appeared on his face.

"So anxious to deal with the basilisk?"

"Don't they know that Old Dumbledore's Fox is in Nirvana?"

"Or are they confident enough to deal with the basilisk?"

"That's interesting. Let me appreciate your skills!"

An interested smile appeared on Lin Zhongtian's face, and his vast spiritual consciousness stretched out without hesitation, locking onto the secret room deep underground. Then he gently swiped his right hand, opened a silver portal, and entered it.

…

On the other side, Ander had summoned all the corpses, including five giant gray bears and more than thirty ferocious wolves.

Densely packed Inferi crowded in the dark and long tunnel, while Ander and Fana sat on the back of a grizzly bear respectively, holding the reins that Ander had prepared in advance and followed the army of the dead.

Soon, passing the corner ahead, Ander saw the outline of the coiled giant snake.

That was the skin that the basilisk had just shed. The green snake skin was extremely bright and it looked like a very precious thing.

Without hesitation, Ender ordered the Inferi to fold the snake skin and stuff it into the suitcase, and reached a verbal deal with Fana for a 50-50 split.

With the undead army leading the way, these maze-like winding roads did not emerge at all.

Soon, the Inferi controlled by Ander discovered a closed wall with two snakes entwined with each other carved on it, and four emeralds shining with strange colors were embedded in their eyes.

Here it is!

Ender looked at Fana, then cleared his throat and imitated the Parseltongue that Tom Riddle had taught him.

"Open!"

With a low and hoarse hissing sound, two entwined snake sculptures began to wriggle as if alive, crawling along the wall. The stone wall in front of them also cracked in the middle and slowly moved to both sides as the stone snakes crawled.

The stone gate opened, and Ander waved his magic wand, and the army of zombies surrounding it immediately poured in.
