Suddenly, Alan's eyes lingered on one spot on the wall, and it seemed—it was a letter.

"Clean up. Alan cleaned the walls of the black blood stains, revealing the walls that had been obscured before.

There are several mysterious runes carved into the walls, which are runes.

Allen made out the pronunciation of the word: "Ashadron".

"The ancient dragon, according to the legend of Oak Village, has to do with the barren state of the Ash Plains. Hermione thought of the information she had written down in her notebook.

Alan nodded solemnly and continued to observe.

The circular tower stretched upwards to a height of about thirty feet, but the spiral staircase leading to the top of the tower was completely shattered.

In addition to the entrance, there is a wooden door on the left and right sides of the hall.

Alan looked around and raised his wand.

"Detect the secret door. In my experience, in such an environment, with this spell, there will always be a reward. He looked back and said to Hermione and Luna with a smile.

Following the instructions of "Detect the Secret Door", in the hall, a stone secret door that seemed to be integrated with the stone wall appeared in front of the three Allens.

Alan once again checks the door for dangerous objects such as spells and traps, and finds a needle prick device similar to the one that hurt Maggie in the first place.

The stinger mechanism is set on the switch, but the poison attached to it has long since become ineffective.

Of course, even if the trap is triggered, it will not damage Eren wearing protective gloves.

The three of them walked into the secret room.

The chamber was damp and cold, and the three skeletons sat quietly on the floor, their empty eyes staring at the opposite wall.

They look like they've been dead for a long time, and the quiver on their body has basically been reduced to pieces.

"I remember that among the ruins on the outskirts, there was a place that looked like an ancient arrow tower, and maybe they were archers. Hermione guessed.

"And probably living a good life. Luna's eyes swept over their hanging bows and arrows. ”

"Huh?" Luna's pale silver eyes widened in shock.

Suddenly, the eyes of the three skeletons on the opposite side flashed red, and they slowly stood up from the ground, their skeletons creaking.

They stretched out their arms, bent their finger bones, and charged at the trio.

Obviously, although they were once archers, they now prefer to fight with their claws.

"Fragmented. Allen's spell caught up with the skeleton in the middle.

In an instant, the skeleton's joints were scattered all over the place, its skull rolled into the corner, its mouth opened and closed helplessly, and gradually, the red light in its eyes disappeared.

Alan tried to keep shooting and get rid of the remaining two skeletons, but was stopped by Hermione.

"Alan, leave these two skeletons to us, after all, this kind of actual combat opportunity is rare. Hermione said.

She drew her wand and looked at them firmly, Luna had defeated the two Dinosaurs before, so this time, she had to deal with them before Luna.

Alan nodded in agreement. He originally felt that this thing was a bit dangerous, and wanted to deal with them in one go.

However, after listening to Hermione's words, he felt that it also made sense, anyway, at most he would suffer a little skin trauma.

"I just tried the super magic technique - spell enhancement ......" Alan reminded before he finished his words, and he had already started to move.

"Fragmented. Hermione cast the spell and hit the skeleton on her left.

However, the skeleton's bones only cracked a little, and one arm flew to the wall.

It staggered and pounced, and Hermione was caught off guard, stuck in the shoulder by the skeleton's finger bones.

Thankfully, Hermione was in uniform and her finger bones weren't inserted, but Hermione still felt a dull ache there.

It seems, at least, it's bruised.

Hermione used "Split" again, and finally turned the skeleton in front of her into fragments.

On the other side, Luna used "Blazing Fire", and the skeleton that pounced on her instantly burst into flames.

"Hermione, are you alright?" asked Allen as he stepped forward, concerned.

Hermione rubbed her shoulders and shook her head in frustration.

"The Split I used was a test of the supermagic technique, the spell boost, and it took about four times as much mana to double the power of this spell. Alan explained.

"Actually, you can find magic based on the characteristics of the undead, such as the blazing fire used by Luna. Muggle research shows that because human bones contain phosphorus, phosphorus oxidation is produced when it reacts with water or alkali, and it burns when it reaches the burning point through the stored heat. ”

"Another example is the undead zombies, there is basically no water on their bodies, but combustible substances such as fat are still preserved, so a little bit. Even more powerful undead creatures, such as vampires, you can learn almost all of the undead's nemesis spell, 'Sun Flameburst', to deal with them in the future. ”

Hermione hung her head, frustrated. She had also seen what Alan said in books, but when she was fighting just now, she didn't remember it.

Luna walked over to where the skeletons were sitting and picked up three crossbows.

"The crossbow is of good quality, and it seems that they had a good time before the castle sank into the ground. The sinking of the castle caused them to die instantly, while also turning them into undead. Alan sighed.

"Hey, there's some ancient gold and silver coins here, just in time for a souvenir. Alan gave the intricately patterned gold coins to Luna and Hermione.

"It seems that this chamber has not been discovered by werewolves. The stone door was closed again, and the three of them continued on their way.

Back in the rotunda, they chose the left-hand direction and walked to the antechamber of the castle.

It is a room about 20 feet wide, and the stone walls around it have not been repaired for many years.

The southern wall had completely collapsed, almost merging with the dirt and rubble outside the wall.

The west wall looks in the best condition, and a fine stone door remains in the wall.

The stone door is carved with a dragon standing tall, and Alan has found a keyhole near the dragon's mouth.

The relief on the stone gate depicts a giant dragon in battle. The door was tightly locked.

Eren first checked the door for spells and traps, then stepped forward and listened carefully for the movement inside the door.

Hermione and Luna watched his movements and took them to heart.

For Allen, doing this every time before opening the door is a better way to stay safe.

"Alajo Cave opens. Luna tacitly cooperated with Eren again, cast a spell, and the door opened.

The stone door was easily opened by Allen, and it was a showroom.

There was a thick layer of dust in the showroom. There are three recessed closets on the north wall, and the same closet on the south wall.

There is a small crystal ball in the closet.

The three crystal balls on the north side have dimmed, while the crystal balls on the south side emit a soft pale glow.

The mysterious runes on the surface of the crystal ball reflected shadows on the walls and slowly moved with the change of light.
