The strange portrait trembled slightly after the two walked by......

They left the wall, floating silently behind them.

The portrait in the picture has long since turned into a hideous ghost, baring his teeth and claws, leaning out of the frame.

"Be careful!" Garcia felt something wrong behind her, and when she turned around, the holy sword had already been slashed.

A portrait was struck and burned by the golden flames.

"Don't be so nervous, little ghost. ”

Ye Ling calmly grabbed a portrait, forcibly tore off the drawing paper with the evil spirits attached, and rolled it into a paper tube, "This thing is interesting, come back and give it to Shen Jixuan to play with." ”

If you can use the Demon Mark Castle as a verandah to wander around, I'm afraid that Ye Ling is the only one in this world.

Garcia shrugged and followed behind Ye Ling, she was really useless as a Valkyrie.

At the end of the corridor, Ye Ling found that the structure here was very interesting, with a floor-to-ceiling glass door that could lead directly to the outside.

In the room on the left hand, there is a gap where you can stretch your hand.

Similar to the post office in Yuyang City, this is indeed the castle's small mail room.

At that time, there were thousands of people living in this huge building, and this was the place where they received and sent letters.

Interestingly, the doors and windows of this small post office are all made of metal, and the windows that were originally used to receive and receive letters were sealed with metal plates, so Ye Ling couldn't see the situation inside.

Ye Ling tried to push the heavy metal door, but found that the door was actually pushed open directly after encountering a little resistance!

The two walked into the house one after another, and Ye Ling found that just behind the door, there was actually a corpse that had not yet decomposed!

It was a female corpse with a serene face, undamaged by the demons.

She was dressed in golden armor and had a sword scattered around her hand.

The ritual sword, which had lost its blessing, became fragile again and broke into several pieces.

Under the ribs, there was a deep wound, Ye Ling guessed that it was the fatal injury of the female corpse, but the wound did not bleed.

"She's a Valkyrie......" Garcia looked at the female corpse blankly and said, "From the previous generation." ”

"The last generation of Valkyries died in this place?" Ye Ling pursed her lips, raised the corpse's arm to examine, and found that her other hand was holding a key.

Obviously, this is the key to the metal door.

"This lady must have discovered something. Ye Ling looked at the key.

Garcia also crouched down to check, and she found that next to the key, there was a faint notch on the wrist of the Valkyrie's corpse.

“A393，X105,W651。 Garcia read the words on the notch.

"It seems to be some kind of number?" Ye Ling frowned.

There was a hoarse roar outside the door.

A demon with two horns squeezed through the door.

Ye Ling didn't stop thinking, he unscrewed off the demon's head with his hand, fed its evil soul to the Seven Star Sword, and then threw the corpse with a different body out of the room, and locked the metal door with the key by the way.

A series of actions flowed smoothly, and the demon became the nourishment of the Shaking Light Star without knowing it.

The enemies that Ye Ling usually encounters all like to taunt a few words before being defeated, Ye Ling originally felt quite annoying, but now that he thinks about it, this kind of monster that doesn't talk is not as interesting as those jumping clowns.

As soon as the door was locked, no one bothered them.

Garcia stood up and walked over to the rows and rows of bookcases in the room.

"Every time you guess, it's the number, it's the letters that are left here, some of them are not sent, and some of them are not received. ”

"This Valkyrie must have found something, let's look for it according to the number. ”

Garcia nodded, and according to the number of the cabinet, she started with A393.

"Found it!" she pulled out a yellow, brittle envelope.

The letter was not signed to the recipient and was not waxed, but the sender's name was Karl.

This letter was written in the Mags language, because of the long time and many ancient grammars, Ye Ling couldn't cut it at all, so the letter was translated by Garcia.

[Hi, Mom, I don't know if you received the salary I sent back last month, Lord Duke is the kindest patron I have ever met, after knowing your leg injury, he gave me a large amount of extra medical expenses, let me send it home for your treatment, if your leg is better, you must remember to thank Lord Duke for your help, but——]

At this point in the letter, the gardener's handwriting, whose name is Carl, suddenly becomes strange.

His handwriting trembled, as if he had remembered something terrible as he had written a letter.

It reads as follows.

[But, Mother, I may have to resign after the New Year, because the Duke has become a little strange, you know, there are thousands of servants in this castle, and every few days, new servants come in, because the old servants will fall ill and leave, or even die of old age, and that day when I was mending the garden, I saw the Duke quietly returning to the castle with a body bag on his back in the cemetery...... I don't know what the Duke did this for, he is indeed a good man, but I have been feeling in danger lately. Please be a little strapped lately, I'll go find a new job as soon as possible, love your son, Carl. 】

Obviously, the letter was not sent, and after a hundred years, the gardener named Carl had long since turned to dust.

They quickly found the second letter.

The contents of this letter are very similar to the previous letter from the gardener, but she is a lady-in-waiting who cleans the duke's room for a living, and has a higher status than the gardener, and has more contact with the duke.

In her letter, she said that the Duke had been mysterious, and from time to time he had locked the door of his room, and that he had been closing it for a day.

Again, the Duke forgot to lock the door, and she went in to clean up in a daze, only to find that the house was empty, and there was no Duke in sight.

The Duke did not know about it, but the maid felt a palpitation.

The last letter was even more mysterious, he even said that there had been a demon's low roar in the duke's house, and he felt that the duke might have been corrupted by the demons, so this castle was full of strange things.

Ye Ling rubbed the tip of his nose and said, "This duke seems to have a big problem, and many letters related to his abnormal behavior have not been sent. ”

"When I was a child in the Holy See, I did hear some clergy mention the duke, and they didn't even say his name, but simply replaced it with the title 'Demon Duke of Fort Canduras'. ”

Ye Ling was noncommittal about this title, at present, although these three letters all mentioned the duke's abnormal behavior, they all showed that the duke was a kind and friendly person.

That's contradictory.

If you want to find the answer, you can only go to the duke's study and see it for yourself.

Ye Ling twisted the doorknob and opened the metal door.

At this moment, Ye Ling trembled violently.

An ugly face with short fangs stood in front of the door, and as soon as Ye Ling opened the door, he was face to face with him, but he was startled!
