All things are three at Hogwarts

Setting out again, they walked cautiously until they came to a stone door carved with a picture of an dragon and fish playing in the water.

Entering the stone door, this is a ten-foot square room made of stones. In the center of the room is a huge sealed iron bucket, with many water pipes extending from the bucket.

"This should be the location of the underground castle's magical water supply system. It should have been idle for a long time, at least a hundred years." Alan speculated, looking at the rusty iron bucket.

Passing through the site of the water supply system, they came to a very special room.

The walls of this room were painted with simple and scrawled runes, and the paint gave off a faint green light.

"Dragons are everywhere, ruling the land." Hermione translated the runes on the wall.

"It's the legendary dragon again." Allen looked at the room with interest.

The large pit in the center of the house showed signs of a recent bonfire.

"There are some burnt troll skeletons in this pit, as well as some blackened and deformed armor fragments." Luna speculated while standing in front of the pit.

The most eye-catching thing in the entire room is a metal cage directly to the south.

It had a big hole and was now empty and twisted out of shape, unable to contain any living thing without repair.

Allen walked into the cage, squatted down, and observed the situation inside the cage.

"This is dragon excrement. It is very similar to Norbert's excrement. Judging from the amount of excrement and the size of the hole, this dragon is already very large!" Allen stood up and continued to look at it.

There is a wooden platform placed in front of the cage door. There are many scattered items on the green tablecloth.

Suddenly, intermittent sobbing came from the direction of the bedding beside the wooden platform.

The three Allens walked around the wooden platform with wary expressions. A stooped old troll was curled up on a dirty and messy bedroll, seemingly asleep.

He looked so sad that he was sobbing even in his sleep.

But as the three of them approached, he opened his eyes alertly, looked at Allen and the others alertly, and at the same time moved his body towards the corner of the wooden platform, as if this could hide his huge body.

"Who are you? Why are you here?" Hermione tried to make her tone softer and more friendly.

The old troll's expression relaxed a little, and he twisted uncomfortably.

"Mibo raised the holy dragon here, and the evil werewolf stole the holy dragon Kaqix." Mibo's eyes showed fear, and he couldn't help sobbing.

"Kaqix? Is this the holy dragon you raised?" Allen asked.

However, Mibo was unwilling to answer him.

Allen took out some food from the storage compartment and placed it in front of him.

Mibo glanced at the food, became restless, and slowly stretched out his upper body from the shadow of the corner. His huge wrinkled palm grabbed the food provided by Allen, and then quickly retracted it.

"Kaqix? Is this the holy dragon you raised?" Allen imitated Hermione, lowered his voice as much as possible, appeared kind, and asked the question again.

Mibo nodded while swallowing the food.

Allen found many scars on Mibo's body, some of which had not even healed yet. They were probably the souvenirs left by his profession of raising holy dragons.

"Where are the werewolves? Why did they steal the holy dragon?" Allen asked.

"If you tell us, maybe we can help you find the Holy Dragon." Hermione advised softly.

Mibo tried hard to swallow the food in his mouth, "Mibo doesn't know, but the big leader knows. Mibo will take you to see the big leader, Yusdayel. You are good to Mibo and help the troll find the holy dragon. Chief, it’s good for you too.”

Although Allen and the others should be regarded as intruders in Mibo's eyes, when Mibo saw the hope of recovering the Holy Dragon, he still took the initiative to lead Allen and the others to meet the giant leader Yosdayel.

Mibo knew how to avoid triggering the traps set by his own people, and led Allen and the others through the many bow and arrow traps set by the trolls, and arrived at the frontline outpost patrolled by the trolls.

It's said to be an outpost, but it's actually just a small room.

The room was littered with rubble, and a bonfire was burning in the center. A few pieces of low-quality woolen fabric were scattered around the bonfire.

Three ferocious-looking trolls stared at Allen and the others warily. The small space and the smoke of the campfire made the already strong stench on their bodies even more unbearable.

Mibo stepped forward, "I need to take them to see the big leader Yusdayel. They can help Mibo find the holy dragon."

The trolls looked at the three Allens suspiciously, "With these three little humans, do you want to take back the Holy Dragon from the werewolves?"

Allen suddenly stepped forward and said in a neither humble nor condescending manner: "Perhaps, I can let you judge whether we have the strength to recapture the Holy Dragon from the werewolves."

Allen looked at the empty room on the right, stretched out his wand and pointed. In an instant, a flame rushed out and went straight to the room, turning into a torrent of flames, burning everything in the room.

Several trolls stared at the room dumbfounded. Allen stretched out his wand and pointed, and the stone door closed instantly, blocking the raging fire inside.

"Well, you do have the strength. The big leader Yousdayel is near the throne. However, don't anger the big leader and her six elite guards, otherwise, you will definitely be unable to leave this underground castle." The troll pointed out the general direction of the big boss to Allen and the others, and at the same time issued a warning.

The trolls gave way to the passage and let Allen and the others pass.

Allen was secretly surprised that the trolls here had much higher IQs than he had known.

At the beginning, he was confident that with the spells he now mastered, these things were no match for him, so he dared to take Hermione and Luna so deep.

Although now, Allen is still convinced that the three of him will leave this underground castle safely, but he can't help but once again become more vigilant about the creatures in the castle.

"This is the feeding room of the Holy Dragon. There are many rats in it. They are all food for Kaqixi, but now, no one should care about them." Mibo said sadly, unable to help but sob again.

Hermione glanced at it sympathetically and seemed to want to go over to comfort it, but was held back by Luna.

Mibo opened the door, and instantly swarms of rats rushed out and attacked Allen and the others. The air was filled with the smell of rat droppings.

"I think, Alan, a fire spell is needed at this time!" Hermione said, and began to use the freezing spell to freeze the mice in place.

In such a narrow room and so densely packed with rats, it is of course impossible to use the Fire Curse, unless you want to burn yourself to death!

Allen also began to use freezing spells on a large scale until he rushed out of the breeding room.
