This time is the most suitable time to sneak in, the two maids are powerless, Su Yang can swagger around in stealth, Xiao Hei remains vigilant in the air, and once he finds that someone is back, he will inform Su Yang.

Count Vance's mansion is not grand enough, it is also relatively speaking, it is meaningless compared to ordinary people, it belongs to the mansion, Su Yang first found the location of two maids, one is cleaning the living room, and the other is tidying up the kitchen.

"The demonic aura is here." In order to be able to stay in the outside world and try to play his role, the pig's nose followed the faint demonic aura in the air and led Su Yang all the way to the study.

"Study?"

The study is a place where the owner of the house hides dirt and dirt in various film and television dramas, the door is not locked, Su Yang gently pushed the study open a thin slit, just stretched out half of the calf, gluttony immediately pulled Su Yang's trousers, and pointed to the upper right corner of the second floor of the study.

"Sentry Eye?"

Su Yang hurriedly withdrew his right foot, Count Vance's study was like a private library, the upper and lower floors were opened to make a large bookcase five or six meters high, and there was a walkway on the edge of the bookcase on the second floor that only allowed one person to pass, and the maid usually cleaned the bookcase on this floor.

Gluttony whispered, "This is the Eye of the Perpetual Sentry, which will be installed in this kind of place, and must have applied alarm magic, as long as there are invisible units in its detection area, it will emit a piercing alarm." ”

"You know a lot, I'll credit you this time." If Su Yang hadn't been caught in the gluttony, the alarm would have been triggered, which would probably cause the mission to fail.

Su Yang asked, "What is the detection range of the Eye of the Perpetual Sentry?" ”

"I don't know exactly how big, but it can definitely cover the entire study." Gluttony nodded the pig's head and said firmly.

"Is there a way not to destroy the Sentry Eye, shield its detection or alarm effect?"

"Then we'll have to find a Demon Pattern Master to crack it."

Where to find the Demon Pattern Master temporarily, Su Yang frowned, it seems that Count Vance attaches great importance to the study, and it is the first time he has seen the Eye of the Perpetual Sentry, which is more like an alchemy prop than the magic of the priest, and it can be used continuously as long as it provides energy.

Gluttony said: "Its role is to detect stealth units, wouldn't it be good if you just appeared and walked in?" You can't just call it once, right? ”

"Really?"

"Is it good to lie to you?" Gluttony shrunk his neck, he really didn't dare to deceive Su Yang, the unequal treaty restricted him to death.

Su Yang left the stealth state, cautiously walked into the study, looked up at the eye of the sentry, and did not appear anything unusual, which was a little relieved, indeed, as gluttony said, the eye of the permanent sentry only reacts to stealth units.

On three sides of the study are large bookcases five or six meters high, a desk faces the main entrance of the study, and there is a small half-hidden door on the side, leading to the living room of the room.

There are tens of thousands of books in the study, and it is a headache to see densely, Su Yang went to look for the desk first, all of them are reports from the Earl of Vance's domain, and there is nothing personal.

Gluttony shrugged his nose: "The demonic aura is a little stronger, but it's still very faint, either a demon appeared here a long time ago, or there is a guy who has been dealing with demons for a long time." ”

Su Yang asked, "If it's a general who has been fighting demons for the first half of his life, will he carry demonic aura on his body?" ”

"Of course, this kind of character will have a demon-like aura on his body, but a real demon will feel disgusting when he smells it, and that is because he has been stained with too much demonic blood."

Anyway, Su Yang couldn't smell anything, could the demonic aura look like some kind of fox smell? The demons are all sensitive to this smell, and they can detect their own kind from afar.

The demonic aura cannot be used as evidence, and Su Yang also has a faint demonic aura on his body, so it can't be concluded that Su Yang and the demon are colluding.

Although Su Yang is indeed a demon contractor......

There was a sound of footsteps not far away, Su Yang immediately stepped on the desk and jumped onto the second floor of the bookcase, and the whole person lay flat on the aisle, and then the side door of the study was opened, and the maid of the earl's family carried a bucket and a broom into the study to clean.

The maid saw the footprints on the desk at a glance, shook her head helplessly, wiped the desk clean with a rag, and then began to wipe from the bottom of the bookcase, the study is so big, it takes time to wipe it all.

The eye of the sentry was beside Su Yang, and there was no way to start stealthing here, Su Yang quietly poked out half of his head to observe the maid's movements, thinking about how he was going to get out.

The maid had just started cleaning, and there was the sound of broken bottles in the living room, followed by the exclamation of another maid, and the maid who was scrubbing the study hurriedly ran out with a bucket and a broom.

"Oh my God, it looks like a wild cat has come in and knocked over the vase on the cupboard!"

"Fortunately, the thing was not broken, but the water spilled out, let's clean it up quickly, otherwise the housekeeper will scold him when he comes back."

Su Yang breathed a sigh of relief, opened his eagle eye to carefully observe the many books on the bookcase, countless books were neatly arranged on the shelves, Su Yang found that only one book in the entire study room was placed upside down, and the more he looked at it, the more abrupt it became.

The upside-down book was on the second floor of the bookcase, and Su Yang walked quickly in front of him and gently pulled out the book.

With a click, the cabinet behind the desk shrank a small inward, revealing a notch in an inverted pentagram, possibly a secret passage that required a special key to open.

Su Yang walked to the mechanism with the gluttony, and asked the well-informed gluttony to see what the mystery was, and the gluttonous pig's trotters kept rubbing his chin and said, "This is a very complicated magic lock, either ask the extremely powerful magic master to crack it slowly, or you can get the key." ”

"The key is most likely in Count Vance, and even if I can get it, once he finds out that the key is missing, the mission will fail."

Gluttony let out a wicked smile: "Hey, hey, it's better like this, as long as you can see the key up close, I can help you remember the appearance of the key and the carved magic pattern, you find someone to copy a key out, in exchange, you have to eat a whole cow for me!" ”

"Okay, you can eat both ends if you want after success." Su Yang's eyes lit up, this pig's head has a big effect, sure enough, as long as he lives for a long time, the pig can be a doctor, and he has lived for many years as a glutton, as long as it is something that can be touched in the chaotic land, he knows more or less.

Jumping onto the second floor of the bookcase and stuffing the book back again, the mechanism was automatically restored, and Su Yang quietly left the Count Vance's mansion while the maid had not returned to the study.

Xiao Hei circled twice in the air and then landed on Su Yang's shoulder, screaming: "Just now I saw a maid enter the study, so she flew into the room and knocked over a vase, kid, you weren't found, right?" ”。

"Okay, let's try our luck in Central Park and see if we can meet Count Vance."

The start of the investigation mission was fairly smooth, and if the next step was to get Glutton to remember what the Pentagram Key looked like, the next step was to go to Sharisy and see if she could make a copy of the key.
