Auston Castle covers a large area and has a tough architectural style. If the thick iron gate in front is closed, it can be said that this is a small war fortress, easy to defend but difficult to attack.

At night, the party hall in front was brightly lit and laughter kept spreading. The entire castle was constantly running, and various types of housekeepers were constantly arranging the work of the waiters, kitchens, wine cellars, guest rooms... all kinds of services were all included.

After passing the vestibule, the garden was slightly inside, which was considered to be the inside of the castle. Apart from the waiters who delivered things and the guards who patrol from time to time, almost no one walked around, and it seemed very quiet.

At the circular arch at the end of the garden corridor, there are two shiny black fur and strong giant dogs crawling on the ground, and their tails like palm-fried tails swept boredly on the ground behind them.

If anyone who knows the goods here will probably recognize it at a glance. This dog is fierce and fierce, extremely fierce, and even a big man cannot get close to him.

Tak, Tak...

Suddenly, the two northern wolfdogs turned their heads to one side in unison, and something was thrown out from the flowers.

The two dogs twitched their noses and couldn't help but stand up, and their lion-like bodies moved forward, approaching the rolling... bone?

Getting closer, a figure suddenly stood up from the garden. The two dogs' hairs exploded and the dog barked and flew to the man.

“Woo woo…”

Two low sobs, the figure swept over like a strong wind, pinched the wolfdog's mouth and twisted it vigorously.

Kakka...The two dogs fell to the ground.

"Damn it, beasts are beasts. I'll give you food and bite me!"

"Stop talking nonsense, hurry up and deal with it." Another black shadow emerged from the flowers, dragging a wolf dog toward the arch.

Needless to say, these two are Done and Jack.

The two of them sneaked out of the side door while the guests were focusing on the Earl Auston who was greeting him. After changing into night clothes, they headed straight to the inside of the castle.

"This dead dog is quite heavy..." Jack dragged the wolf dog's body into the shadow of one side of the arch, and put it on a lie down. Then he took out a small buckle and placed it under his tail to sweep it continuously. Under the cover of the night, no one would pay attention to these two lazy wolf dogs lying on the ground.

"Go to the study."

Two ghostly figures kept floating, gradually deepening into the castle after avoiding patrol guards...

In fact, the castle is still very cautious, but because of the party, most of the guard forces are adjusted to the front. So after avoiding the previous level, the pressure on Donn and Jack was much less.

Either way and then...

When Tang En and the others flashed over the eaves and avoided a team of patrolling guards, they finally approached the destination - the study.

The study in Tang En's impression is nothing more than opening a house in a house for reading and office purposes. It is not much bigger and easier to search. This is also the reason why he chose the study at the beginning.

But when he touched Earl Auston's study, he was shocked. Is this a study? Library...

It’s no wonder that Tang En has such a rustic mentality, because now the three-story attic is placed in front of him.

The study was naturally locked, but fortunately there was also a professional thief Jack. If Tang En came alone, he could only find a way to remove the windows...

If you want to say that professionals are really professionals, Jack used a soft wire to open the rotary lock on the door in less than ten seconds. Pushing the door into the room, Tang En and Jack gradually looked up and opened their mouths wide. You sister...

A circular bookshelves about eight meters high hit the eye, and various large books stood in line, absolutely spectacular! Absolutely domineering! Absolutely painful... Is such a tall book easy to get?

It turned out that the building that seemed to be a three-story attic outside was hollowed out inside. In addition to this bookshelves, the entire house also had a huge desk, and there were several bonsai in the corner, which looked very empty.

Is there a secret passage here? Don Eun looked at Jack.

Jack was wearing lambskin gloves, holding a small hammer in his left hand and a black iron block in his right hand, and began to study it carefully around the desk, bookshelf, and bonsai.

Tang En naturally couldn't get involved in such professional things, so he stood aside and watched the domineering bookshelf.

After a closer look, Donne was immediately happy. It turned out that the large books were all brand new, without any trace of reading, and they were all decorations.

Thinking about the black beard and Earl Auston who saw him in the hall before, with a thick cigarette in his mouth, Tang En chuckled. I said that guy didn't look like he could study. No wonder some people say he was more like a pirate than a noble.

Jack had already focused on the bookshelf at this time. After a while, he stopped in front of a book, and the black iron block in his hand was now absorbed on the wooden stand.

Magnet...Tang En suddenly realized.

Jack took down the rows of books and frowned. The back was empty and knocked on the wooden cabinet, the sound was dull.

"The secret passage should be behind this, but the triggering method is difficult to find..."

"Can't you forcefully break it?" Tang En asked a special layman.

Jack opened his mouth speechlessly: "Brother, we are thieves now... and if this device is forced to be broken, it will definitely call the police."

"What should I do now?"

"I guess the triggering method is still on these books."

"No way..." Tang En looked up at the hill-like bookshelf, "You can't handle these books until tomorrow morning."

"There must be some clue. Earl Auston is vulgar and complicated. "Jack's eyes kept sweeping across the rows of bookshelf.

After hearing this, Tang En had to walk to the other end of the bookshelf to observe. I have to say, the pressure is so great! After reading a few lines, Tang En felt dazzled and felt uncomfortable with his neck tilting. He was distracted, Damn, which line was coming just now...

Hey!

Tang En, who had to observe from scratch again, suddenly moved his heart and his eyes swept back to those books.

"The Faith of Warriors", "The Essence of Sword Forging", "Thorn Flower", "The Art of War Command"... Why is it a bit wrong? Well, what's wrong?

The consciousness in Tang En's mind told him that there were problems in these books, but this consciousness was not strong enough to blurt out, as if it was stuck in his throat, which was really uncomfortable.

"Don't be anxious, don't be anxious..." Tang En tried hard to calm his mind, "If you have any questions, it means that one of the books is different from the others. It is difficult to find the differences, so let's find common ground first...uh, common ground?"

Bang, Tang En slammed his hands and said, "I understand!"

"Brother, please keep your voice... Uh, you know?" Jack, who was almost dizzy on the other side, was awakened by this sudden sound.

"Sorry, sorry, I'm a little excited... Well, you see all the books here, they are mostly arranged in alphabetical order, but there are a few of them... For example, the thorn flowers in this line have obviously different initial letters from the surrounding ones, and it shouldn't appear here."

"Ba, yes." This time Jack was excited, and he quickly lifted the ladder standing on the side and twitched the book, hissing...

With a light sound, the book was put down from top to bottom, and it was obvious that there was an iron wire as thick as a little finger inside.

With this precedent, the next few books with wrong placement were quickly found.

As the sixth book was opened, the bookshelf where the magnet was first inserted suddenly slid silently to both sides, revealing a bright silver metal plate with a handle.

Jack cheered and rushed forward and pulled the handle.

Well……

There was no passage behind the metal plate, but instead a huge crystal lock with red, blue and yellow light appeared.

"Not..." Jack grabbed his hair and moaned, "Three-color magic lock?"
