In the middle of the night, three figures appeared silently in the corridor on the second floor of the castle like ghosts, stopping not far from the Blood Word, which had been erased by this time.

"Is this it?" Qi Fang gently tapped on the wall in front of him, but did not hear the echo of the hollow. Hogwarts has a special magnetic field that protects the entire castle, so much so that even his mind can't penetrate the walls.

"Yes." Su Quan nodded affirmatively.

Qi Fang put his palm on the wall, and the divine power gushed out, only to hear a soft sound of "poof", the wall was shocked into powder by the divine power, breaking a hole the size of a door panel, looking inside, you can see a pipe that slopes downward.

The basilisk crawls along these pipes and haunts the castle.

Qi Fang and the two women glanced at each other, and then jumped into the pipe, sliding down like a slide.

These pipes do not go straight up and down, but extend downward in a spiral.

The three of them slid down the pipe for nearly 100 meters, fell into a wider pipe, and slid down for more than 200 meters before falling to the ground.

"It's a naturally occurring underground cavern, at least two hundred meters above the ground." Qi Fang looked at the environment in front of him, his spiritual power radiated out, and he poked around, and then, the corners of his mouth were slightly hooked. "We've come to the right place, the Chamber of Secrets is right ahead."

The three of them walked along the undulating cavern, and soon saw a huge snake molting, twenty meters long, and its staggering size.

"If it were in the world of Eastern mythology, this giant basilisk, which has lived for nearly a thousand years, would have become a refinement long ago." Qi Fang put the snake away and continued on his way, soon coming to a hand-hewn stone wall.

In the center of the stone wall is a circular iron door with seven snake-shaped reliefs of different lengths, and the snake's head is stuck in the door frame like a latch.

Qi Fang stepped forward, pulled out Mandela's dagger, cut off the heads of the seven snakes with a "ding", and then pried it hard to open the iron door.

Behind the iron gate is a circular corridor seven or eight meters long, three people pass through the corridor, and then come to a small square, there are sixteen huge snake head statues on both sides of the square, the mouth of the snake is wide open, the appearance is infiltrating, the end of the square is a giant human head relief about ten meters high.

This is the secret room left behind by Salazar Slytherin.

The eyes of the three of them fell on the relief of the human head opposite at the same time, which carved the Slytherin in his old age, with a resolute face and a beard.

"The statue's mouth is a movable mechanism that can be opened to release the basilisk. For such a long time, I really don't know how the basilisk survived, don't snakes need to consume energy when they are sleeping? Qi Fang vomited.

Hogwarts was founded in 993 A.D., exactly one year in the middle of the day. Even if the basilisk didn't live for a thousand years, it lived for at least eight hundred years, and during this time, only Voldemort opened the secret room, and the rest of the time was locked in the secret room, never came out to move, and it was indeed not easy to survive.

They don't know snake language, and even if they know snake language, they don't know the spell to summon a basilisk, and if they want to open the mechanism, they can only use the most primitive and violent methods.

Qi Fang stepped forward, punched down a few times, blasted the statue's mouth open, and then jumped up to the top of the statue's head.

A "hiss" sound sounded.

The basilisk was awakened by the sound of the stone statue bursting, and slowly crawled out of the cave, and as soon as its body stretched out five or six meters, Qi Fang jumped down from the stone statue, and smashed its body like a meteor shining with golden light, stepping on one of its bodies into the ground, and the powerful impact force shattered the ground within a few feet.

"Click!"

A soft cracking sound rang out from the basilisk's body, and its spine snapped with one kick.

The head of the snake raised its head, its mouth opened, and let out a roar of pain, the head of the snake swung violently a few times, and slammed heavily on the ground, the yellow snake pupils the size of a sand bowl gradually lost their lustre, and blood spilled from its mouth and nose.

The basilisk, which had lived for nearly a thousand years, died so simply.

Qi put his hands around the basilisk's body and dragged it out of the cave, its entire body was nearly thirty meters long, making it the largest animal he had ever seen.

The trio skillfully unravel the basilisk.

Wan Wan took off the two eyeballs of the basilisk and said, "This pair of eyes belongs to me, and I can use it to practice a pupil technique." ”

This is a pair of snake pupils with magical powers, which emit a deadly ray that kills all living creatures that see the snake pupils, and is no less powerful than the 'Avada Suo Curse'.

Su Quan took out a soccer ball-sized snake gall from the basilisk's belly, and the dark green snake gall bladder exuded a fishy smell.

"The snake gall belongs to me, but it's a pity that some elixir is missing, otherwise I would use it to prepare an elixir that improves my strength." Su Quan said with some regret.

"There are not many herbs in this world, you can go to the library and look it up, maybe you can find herbs with similar medicinal properties." Wan Wan said.

Su Quan nodded slightly.

Qi Fang put away all the venom glands and snake teeth of the strange snake, and said calmly: "Without snake venom, I don't know if Dumbledore can destroy Voldemort's Horcruxes." ”

Horcruxes are protected by powerful black magic, and there is no way to destroy them by ordinary methods, as mentioned in the book "Secrets of Cutting-edge Black Magic", the Horcruxes that can be destroyed must be very destructive, so powerful that Horcruxes can no longer be repaired with magic.

Basilisk's venom is a very strong poison with only one antidote---- Phoenix's tears.

Therefore, snake venom is an effective way to destroy Horcruxes.

In the plot, all the Horcruxes were destroyed by the snake's fangs and the Gryffindor Sword that absorbed the snake's venom, and now that there is no snake venom, Dumbledore has no choice but to destroy the Horcruxes.

The snake pupil, snake venom, and snake gall are the three most valuable parts of the basilisk, and in addition to that, this body of flesh and blood.

"The basilisk has lived for nearly a thousand years, and its flesh and blood are full of abundant energy, more powerful than an adult dragon, and it can't be wasted." Qi Fang stuffed the basilisk's massive body into a magic pocket.

"Chirp."

At this moment, the chirping of a phoenix reached their ears, and when Qi Fang looked up, they saw Dumbledore's phoenix flying in from a tunnel, hovering over the stone chamber.

"Fawkes."

Qi Fang did not have any surprise when he saw Dumbledore's birds, the whole of Hogwarts was under Dumbledore's surveillance, and what happened in the castle was rarely hidden from Dumbledore.

"Go back and tell Dumbledore that I've taken care of the basilisk." Qi Fang waved his hand at the phoenix.

Fawkes seemed to understand him, nodded very humanly, and flapped his wings and flew back.
