A few hours ago.

The potion is divided into two stages, one is the refining and extraction of the raw materials, and the second is the rehearsal of the final product, the former requires a lot of time and energy, while the latter only requires undivided concentration and talent for mastering the potion.

And it just so happened that Delphi was a genius, and the last thing he lacked was a talent for mastering potion changes.

The recipes for more than twenty semi-finished potions are a problem for the average student, but it only took Delphi less than half an hour to complete the configuration, and in the torment of the low fire, he got the finished product he wanted—the Fuling Elixir.

"I succeeded, Elixir of Blessings!" Delphi did not feel the slightest tiredness after drinking the clear liquid in the glassware in front of him, but his eyes lit up and his body was full of infinite strength.

"Curious feeling!" Delphi's eyes were bright, and he looked at the room around him that should have been all too familiar: "It was as if a layer of fog had been removed in front of me, and my mind was swift and calm, perfect!" ”

Looking at the closed wooden door, a hint of impulse appeared in Delphi's eyes, and then disappeared, and he sat on the bed and closed his eyes: "The potion experiment has taken a lot of my energy, and I need some time to readjust my state." ”

Ding Dong –

Just as Delphi closed his eyes to adjust his physical condition, a crisp bell rang in his ears, and it took a full twelve beats before it stopped, marking the beginning of the school curfew.

"The curfew has begun." I don't know how many hours have passed, Delphi suddenly opened his eyes, glanced at the clock hanging on the wall, and his face was calm: "In the dead of night, it is a good opportunity to act." ”

At the same time as he walked out of the door, a large amount of knowledge about concealment quickly appeared in his mind, such as 'smell dissipated', 'body hidden', 'silent walking', 'air stagnation'...

With a tap of the staff, a series of spells were pointed in front of him, and then crossed, and the fluorescent light unique to the dotted spell swirled twice, and Delphi's figure dissolved like a pencil drawing erased by an eraser.

But if you can have the ability to 'listen', you can clearly see a brisk figure moving in the castle.

Curfews are a good thing, but they don't do anything for some people, Delphi did, and so did Stelai, who was so good at guessing about people's hearts.

Compared to the purposeful people of Delphi, Slater seemed much more unremarkable, but since the second year after he entered the school, no matter how much the school increased its patrols, he never caught Slater's tracks.

On this day, after the twelve bells for the curfew rang, the air twisted in a corridor that seemed to be empty, and then Slater's figure appeared out of thin air.

Slater, the king of mischief, at least half of the entire academy, whether senior or junior, has been tricked by him indirectly or directly, and he is naturally not a simple person to be able to survive despite offending so many people.

Alchemy herbs, everything, and in alchemy has a unique hand, now this invisibility cloak that can hide people's scents, breath and body shape is his own invention, relying on this garment, even the professor can't find his traces at once.

Putting an earbud called a downwind earbud on his ear to listen to the subtle sounds around him, Slater smiled and pulled out his staff to complete the magic circle that had been triggered by someone during the day.

"What are you doing?" Just as Slater was excitedly arranging a new trap spell, an ethereal sound suddenly reached his ears.

"Don't bother me!" Slater snorted, obviously familiar with the owner of the voice.

"You're on a night tour, I'm going to tell the professor!" The owner of the voice was unrelenting, and the misty white body fluttered in the air for a moment, and immediately blocked in front of Slater: "Unless you tell me what you're doing?" ”

"Oh my God..."Looking at the female undead in front of him, Slater put away his staff and sighed, and said helplessly: "Lilith, shouldn't you be in the toilet at this time, why did you come here." ”

"Lilith can go wherever she wants." The undead Lilith replied dissatisfiedly, then looked at the trap laid by Slater with curiosity, and stretched out her hand: "What is this?" ”

Hiss—

There was a soft sound, and Lilith's palm passed directly through the trap without triggering it, but this only piqued her curiosity even more: "It's fun." ”

On the other side, looking at Lilith who was curious like a child, Slater just rolled a pair of dead fish eyes and looked at her quietly.

Lilith, the undead, one of the Academy's most prominent spell schools decades ago, was killed by an accident that caused her body, and although her soul was retained due to her powerful spell skills, she was also irreparably damaged, and she had an adult body and an early personality.

Immortal but unable to keep a memory in her mind for too long, she has witnessed the campus career of I don't know how many classes and students, but none of them can occupy a place in her memory.

In this college castle, Lilith is a curious child who can never touch reality, she is always attracted to what she thinks is special, and then after a while, this precious memory is completely lost.

The only difference compared to the others was that Slater had so many contacts with her that Slater himself could not count, and each time Lilith floated over like a curious silly roe deer, and left with a smirk after being dealt with by Slater.

Lilith is very easy to dismiss, she only needs a lollipop-like thing to get rid of it, and she doesn't have to worry about the possibility of informing, but even Slater can't afford a special lollipop a day, so she thought of a good way.

He made a special case in the abandoned girls' toilet on the third floor of the castle, which was roughly like a playground, and could lure Lilith over, but now it seemed that something was wrong.

"The induction circle set up in the toilet has failed, and it looks like it is going to be rearranged again..."Slater didn't care about Lilith, who could play with both the trap and the trap in front of her, and put on the invisibility cloak and wanted to go to the toilet.

Completely disappearing from her figure, Lilith suddenly lost her Slater figure, and after being sullen for a while, she looked back at the trap spell in front of her: "Bad guy!" ”

Not long after, Delphi passed by this corridor, and at a glance saw Lilith who was looking at a clearing in a daze, and his brow suddenly moved: "Undead Lilith, what is she doing here?" ”

Touching the center of his eyebrows with the tip of his staff, Delphi's lie instantly turned a strange color, and after looking at the open space in the corridor again, he clearly saw the various spell traps laid by Slater: "It's Slater's method again, it seems that he hasn't been gone for long, forget it, don't care about him." ”

With that in mind, Delphi took another step and walked quietly past Lilith, completely unnoticed.

"Here it is." In a corner of the third floor of the castle, looking at the sign hanging on the door in front of him, Slater showed a smile, then coughed twice and quickly put the smile away, looked around for a while, pushed open the toilet door and flashed in, and then gently closed it.

In the middle of the toilet, there was a broken spell pattern and scattered various things, as if someone had been cut alive from the middle, and the corners of Slater's eyes twitched: "I took it, I deliberately built the magic circle in this place, why would anyone come here to destroy it!?" ”

Gritting his teeth, he cleaned up the still useful things scattered around him one by one, and Slater looked at the only entrance and exit of the entire toilet with bad intentions: "You like to wreak havoc, don't you?" I'll let you wreak havoc! ”

"The stench, the mud bombs, the chains, the flames..."

In a gloomy laugh, the wooden door that had already looked a little dilapidated above the original knowledge was engraved by Slater in an unimaginable way, and among them, a small half of the alchemy materials he had just brought back were used up again.

After doing all this, Slater left in a relieved mood and took the wooden door back with him, as for Lilith's magic circle, it felt good to have it under the atrium.

In the atrium, a silver-white disc was buried in the soil under the atrium against the sky that had gradually become a trace of fish belly white, Slater nodded with satisfaction, and then saw Jiang Xin's figure leaving the castle: "Huh? This guy, I remember it's a new auditor, it seems to be called Jiang Xin? ”

"What did he do when he came out so early?" Curiosity rose in his heart, Slater glanced at Lilith, who was already playing in the magic circle, took out the invisibility cloak and put it on, and quietly followed behind Jiang Xin.

Not long after Slater followed Jiang Xin out of the teaching castle, Delphi, who was densely covered with nearly ten kinds of spells, stood in front of a wooden door that looked a little damaged because it had been abandoned for many years: "If I'm not mistaken, this is it." ”

With a confident smile on his lips, Delphi reached out and pushed open the wooden door, which didn't look anything out of the ordinary.

The next moment, the various trap spells that Slater had placed on the toilet earlier were instantly activated, using one-time energy crystals as a supply source, and the dazzling light of the spells made Delphi's eyes widen: "! ”

Rumble!

A loud explosion rang out, and crimson flames roared like dragons in the cramped environment, along with sticky, foul-smelling brownish-yellow mud like some kind of disgusting food, and more spells.

Enraged, in the face of the already surging spell attack, Delphi used the fastest hand speed since birth, and in just an instant, he used a variety of spells: "Multiple Spells - Armor Protection!" Air Barrier! Flowing water barriers! The smell dissipates! Everything cancels off! ”

Slater's inspiring spells collided with the many spells that Delphi had unleashed with all his might.

The white mist and water vapor produced by the collision of the flame and the clear water, and the mud that dispersed the foul smell passed through the fog and turned into a puddle of muddy water and hit the invisible air barrier, the shock wave raged, and the thunder snakes were everywhere, and in just a short moment, this small corner turned into a ruin.

The strong fluctuations caused by the collision of spells and explosions instantly shocked the entire school, and Jiang Xinslater and the others, who had already walked outside the teaching castle, were no exception.

Looking at the castle on the third floor, where a window had been shattered by tongues of fire, Slater's eyes were full of fear: "What!?" How long has it been since the trap I put in the toilet exploded? Is there a secret room or a treasure there? Where are you going to go despite the curfew? ”

The next moment of exclaiming, Slater seemed to realize something, and immediately covered his mouth with his hand and wanted to leave, but suddenly heard a 'gloomy' voice 'exploding' in his ears: "Found you!" ”

Phew——!

The wind made fire, and purple flames roared out, turning from sparks to prairie flames in a short breath, and then retracted, like a storm of fire, enveloping Slater in the eye of the storm.

"Misunderstanding! Misunderstand! Feeling the faint threat on the flames, Slater hurriedly put away his precious invisibility cloak: "Meet me, my name is Slater, and I am also a student in this academy, not an outsider!" ”

"I didn't sleep in the middle of the night, and it was a misunderstanding to run out to follow me?" Jiang Xin smiled: "Then I made a mistake and burned your hand, which should be regarded as a misunderstanding." ”

"Wait!" Seeing that the purple flame vortex was retracted again, Slater's face suddenly became bitter: "Tell me about your conditions!" ”

"Condition..."Jiang Xin glanced at the castle: "That explosion, do you know what's going on?" ”

"Yes." The explosion of the castle must not be hidden, and Slater has no need to hide it, so he simply nodded: "In the abandoned women's toilet on the third floor, I only set it up a few hours ago, but I didn't expect it to be stimulated so quickly." ”

"Abandoned women's restroom?" Jiang Xin was stunned for a moment, and his eyes were full of disdain and disdain when he looked at Slater: "You went to that place and put a spell trap with such a great power to blow up the toilet?" ”

'Well, I can't explain it! ’

Sensing Jiang Xin's eyes, Slater's mouth opened, and finally nodded with a disgraced face: "That's right, I ran to that place and set off a bomb." But I have a reason for that! ”

"Okay, I don't want to hear you explain why you're going to blow up the women's bathroom, all you have to do now is make amends to me, and we'll run away."

"Okay!" Slater nodded happily, reached out and threw a pendant out: "The Moon Hidden Pendant, an alchemy product that can hide the smell of people, only this one on me can give you." ”

Reaching out and taking the Moon Hidden Pendant and looking at it, Jiang Xin put it in his pocket, waved his hand to remove the purple flame, and disappeared into an afterimage: "Good news for you, I noticed that the professor's breath of the academy was coming. ”

“？？？！！！” Slater was stunned for a moment, then his face changed suddenly, and he was about to take out the invisibility cloak again, but before he could put it on, a numbing voice sounded behind him: "Slater, I see you..."
