On the night of July 11, 2018, Nanheng City, heavy rain.

The heavy rain that fell in the south of the Yangtze River in the Western Regions the day before yesterday seemed to have been replicated in Nanheng City, and the torrential rain was like a pour, and the figure of the person could not be seen clearly three steps away on the road. The heavy rain brings a rare coolness in midsummer, and most of the residents of Nanhengcheng choose to rest early and sleep well while the weather is cool. There was no sound in the city except the crackling of the rain.

Brian, Filch, and Meng Yuchen were all dressed in black, hiding in the rain, and hurried towards the magic research line under the Mountain City Academy.

The study of magic requires a relatively quiet environment, and naturally it is impossible to be in a downtown area. Therefore, the institute is also on the outskirts of the city, and it is not the same district that is only suitable for Brian and others to live in. But it's also relatively remote.

The three of them traveled very fast, and they arrived outside the research institute in ten minutes. The doorman of the institute hid in the gatehouse to shelter from the rain. As Wolf, who had excellent eyesight, Filch could clearly see that the four doormen in the porter were playing cards.

Although there are a lot of valuable magic materials in the Magic Research Institute, there are also magicians who have been experimenting for a long time. It's not easy to steal. In addition, the precious material storehouse has forbidden magic protection, so few thieves who don't open their eyes will pay attention here. It is because the guards are not very vigilant, and coupled with the heavy rain in the sky, they naturally have more entertainment.

The three of them were a little closer, and the doorman, who was having fun, didn't notice it. Filch cautiously let out the detection magic and sensed it, and shook his head at this Brian and Meng Yuchen, indicating that there was no defensive type and alert magic in the perimeter. Filch served as a temple guard before defecting from the temple, specializing in the safety of the temple's priests and dignitaries, and was familiar with the elemental fluctuations of various vigilance magic. If he says no, then there must be none!

Brian nodded, pointed to the guard's room, and made a throat-slitting motion. Stretching out another index finger, he made a silent gesture in front of his mouth and looked at Filch.

Filch nodded, and quietly leaned towards the guard's room.

The guards were still happily playing cards and shouting, when they suddenly didn't know that death had quietly come!

Filch leaned over to the door of the janitor's room and found it hidden. Raise your hand slightly, set off a gentle breeze, and slowly blow the door open.

One of the doormen heard the sound and glanced at it, and when he saw that there was nothing unusual, he continued to take the cards. Filch waited quietly for five seconds, there was nothing unusual in it, it was still noisy, and he decided to do it!

Filch took a deep breath and slammed into the door. One of the guards facing the door was startled and opened his mouth to scream, but before he could make a sound, the rapidly spinning moonblade had already slashed his throat. The doorman, who had had his trachea severed, couldn't make a sound, and with shock and fear, he clutched his throat and collapsed. And before he fell, Filch had already released another moon blade, directly slicing the neck of one of the doormen on the left, a human head was thrown high, and at the same time, the moon blade that slashed through the throat of the first doorman made an arc, tearing open the throat of a doorman on the right who had just uttered a syllable and didn't know what to say, splashing a large handful of blood.

And Filch was already the last one, with his back to the doorman, covering his mouth with one hand, fixing his body with the other, and with a click! The doorman's head was twisted to the opposite side, and his tibia was instantly broken. It was only then that the first doorman who had been attacked fell to the ground. Filch raised his hand and caught the swirling Moonblade. Glancing at the alarm ball placed on the table, as soon as it was pressed, the magic alarm of the entire research institute would go off, but none of the four guards had time to ......

From beginning to end, there was hardly any movement except for the sound of three doormen falling to the ground. Filch walked to the door, opened the door and gestured to the outside, and Brian and Meng Yuchen flashed out of the rain and entered the guard room.

"Filch made a move, and it was really neat!" Meng Yuchen smiled and glanced at the four corpses in the room.

"It's just four mid-level samurai, it seems that Yamashiro really doesn't care much about this institute!" Filch replied flatly. With only four mid-level samurai, if it weren't for the fear that they would raise the alarm, even if it was a head-on conflict, Filch would not be more confident than ten seconds!

"Wouldn't that be better!" Brian smiled, "It's just convenient for us to move, but ......" Brian frowned and glanced outside, "Why hasn't that haunt come yet?"

"Probably hiding somewhere, that unsightly fellow!" said Filch, foaming at the mouth, indignantly.

Of the three, Filch had the greatest opinion of the enemy. The first time the vengeful spirit appeared, in order to prove himself or to establish his authority, he used mental magic to control Filch as soon as he made a move. Filch didn't even know what was going on from start to finish. Afterwards, Filch was very angry, but the enemy always saw the beginning and the end, and the action was very secretive, and Filch never had a chance to find a way back. Of course, even if it goes head-to-head, with his strange magic, Filch is not sure of victory.

The three of them couldn't find the enemy, so they simply didn't find it. I'm going to continue to the institute.

Filch found a map of the entire Institute's defenses in the janitor's room. The three of them had already obtained the structure map of the research institute from other sources, but they did not get this defense layout map, and they could easily get it here at this time.

The circles of various colors on the layout map, the clouds and mountains and fog covered by Brian and Meng Yuchen were seen, but Filch could see it clearly, and couldn't help but smile and said: "This is a great help, there are actually three secret sentries of high-level magicians, if you don't see this, you may not be able to find it! Maybe there will be a lot of trouble." ”

"What is this, why can't I see anything?" Meng Yuchen looked at the picture with a painful face, there was not a word on it, I don't know how Filch could read the information.

"It's a very standard defense layout map, I've seen a lot of this stuff before!" Filch shrugged disapprenously: "Let's go, be careful, there are three detection spells in the yard, and once you enter the wrong path, it will trigger an alarm, hehe, but everything is clearly marked on it, then it's all decoration!"

Meng Yuchen and Brian didn't say much, and according to Filch's command, they easily walked through the courtyard and entered the building of the research institute, and nothing happened along the way.

When they arrived at the door of the building, the three of them were worried. The door of the building is locked, and the three of them can clearly feel a trace of magic fluctuations from the door, obviously violently destroying the door, which will immediately cause an alarm! And this lock is not an ordinary mechanical lock, but a special magic lock, which can only be opened when a special magic fluctuation touches the core of the magic array. Not to mention that none of the three of them can pick the lock, and even if they do, there is no use in the face of this kind of magic lock! more than two wrong magic fluctuations will also cause alarms.

"Grandma's, what should I do with this thing?" Meng Yuchen looked at the magic lock, his face depressed.

"If it doesn't work, open it violently, and let's solve it quickly. Try to get things and leave before reinforcements arrive?" Filch suggested.

"No!" Brian shook his head: "Nanheng City does not have a confinement magic array that restricts teleportation magic, and this is where teleportation magic can be used!" Once the magic alarm is activated, the masters of the Mountain City Academy can arrive within a few minutes, and the three of us have no chance of winning against a few old guys from the Mountain City Academy!"

"Why don't you go in through the window?" Meng Yuchen asked after a moment's thought.

"I've read too many brain-dead novels, and if the door doesn't work, just go through the window?" Filch said disdainfully: "See for yourself......" He pointed to the building, all the windows were closed, and if you felt it carefully, there were slight magic fluctuations on it: "All the windows are closed, and there are magic alarms, breaking the windows is the same as breaking the door!"

"Then what should I do!" Meng Yuchen complained.

Brian thought for a moment, "Let's go to the top of the building!"

The institute building has 22 floors and is more than 60 meters high. However, this height is nothing to the three of them, let alone Filch, who also has a wind magician.

At the top, there were indeed useful discoveries!

There is a small door on the top floor, and although there is also a sabotage alarm on the door, it is not locked, but locked from the inside with a latch! In this way, the three of them still have no choice, but on the top floor, there are still a number of vents, apparently arranged to ensure air circulation in the building! The vents are very small, only one foot square, and ordinary people cannot get into them at all, let alone have a layer of cover on the surface.

However, it is precisely because ordinary people can't enter, and the cover only prevents small animals such as birds and kittens and pine trees from entering by mistake, so it does not apply magic defense!

Supposedly, there is no problem with the vents set up in this way, and it is difficult for children over the age of five to get into such vents! Not to mention the twisting ventilation ducts inside! And although the ventilation ducts themselves do not have warning magic, if they are damaged by force, the vibrations generated will still trigger the building's warning magic.

Of course, none of the three of them can get into this vent, not to mention that Meng Yuchen is a half-blood elf, he is quite big, even if it is a pure-blood elf, it is impossible for a slender one to pass through this thing. But the three of them can't, but Meng Yuchen and Brian's blood babies can!

The appearance of the blood baby will always be the size of a three-year-old child, but it has half the memory and magic power of the blood mage, and at the same time, it will obey the command of the magician! The three of them carefully removed the protective net of the vent and let the blood baby get in, and then the blood baby opened the door from the inside and entered the building smoothly.

According to the layout plan obtained earlier, the top five floors of the 22-story building are full of various materials and documents, and the next five floors are the rest place of the research institute. Of course, most of the fellows have their own residences and may not live in the graduate school. The lower twelve floors are places for magic research, and two of them are the most heavily guarded, where some precious magic materials and some magic research results are stored.

Brian and Meng Yuchen didn't know where Ji Qingcheng and the three of them lived, and they didn't plan to look for them from room to room. At least not from room to room in the first place. It's too dangerous! If they resist, they will be in trouble if the alarm is sounded! Their first step is to destroy the magic alarm system of the entire building! This is also planned for a long time!

The magic array that controls the alarm of the entire research institute is guarded by three high-level magicians at the bottom of the building, and according to the guard layout map obtained by Brian, there are basically no guards on the top ten floors, but from the twelfth floor onwards, there are a number of guards on each floor, of which the sixth and ninth floors, that is, the two floors that are particularly tight, have two teams of guards, the open whistle and the dark whistle!

"Yes, don't hesitate, do it right away!" said Brian, "don't give them a chance to sound the alarm!"

Meng Yuchen and Filch nodded.

Successfully touched the twelfth floor, and did not encounter the so-called wandering guards along the way. But as soon as he reached the twelfth floor, he was discovered by the guards on this floor! But if the guards asked, they couldn't open the exit, and they were killed by the three people who had been prepared for a long time!

Whether it was Meng Yuchen and Brian's blood arrows or Filch's moon blades, they were all incredibly fast and powerful. The five guards with senior titles were killed without even having a chance to open their mouths! Coupled with the difference in strength, Meng Yuchen and the three of them came to the ninth layer without any danger.

After entering the ninth layer and eliminating the five guards, Brian frowned slightly, according to the information he received, there should be three more secret guards on this floor. But until they solved the five Ming Guards, they didn't find the Secret Guards.

"Oh no," Filch whispered, but then a secret door suddenly opened in one of the walls, and a figure opened the door and went down. The three of Filch were startled, and when they leaned over, they saw that there was a secret room inside the secret door, and all three secret guards had fallen inside. There were three alarm balls on the table in the room, and it was clear that none of the three had time to sound the alarm.

Filch examined the bodies of the three guards, and there were no injuries on their bodies, but the men were clearly dead. Even the expressions of the three of them were calm, obviously being killed instantly, and there was no pain.

"Psychic magic!" Brian quickly concluded, "It looks like the vengeance is already in the shadows!"
