Catherine retracted the unruly black-fronted rat and breathed a sigh of relief. This is the first time she has manipulated both the bull-eyed demon and the black-fronted rat instincts at the same time. With her past abilities, this is almost unattainable.

Especially the black-fronted rat given to her by the demon king, the female mage usually spends a lot of energy and carefully guards it, and she doesn't dare to release it at all. Thanks to Catherine's understanding of the Heart of Nature in the Elven King's world, she was unexpectedly able to communicate with animals and plants, giving her a new understanding of the Black-fronted Rat.

While it was difficult for a female mage to fully command the Black-fronted Rat at the moment, at least the irascible creature was no longer as hostile to her as she had been in the past.

The black-fronted rat's instinct is actually always in a state of hunger, it is always expressing its desire for food, in fact, it is also instinctive that it can never get enough.

Black-fronted rats that do not have enough to eat in the Underworld can become particularly irritable and aggressive. So the hungry rat swarm eating a dragon is not nonsense, but something that really happened.

Therefore, one of the most basic ways to manipulate the black-fronted rat's instinct is to give it directions in the direction of its food, and then let it go and devour it on its own. Of course, the gluttonous black-fronted rat must be pulled back at the right time so that it does not eat everything it can eat.

Although Catherine still hasn't figured out what kind of psychology the demon king gave him the black-fronted rat at that time. But this did not prevent the female mage from using the black-fronted rat to deal with the demon king in turn. Poor Big Devil certainly didn't expect such an outcome.

In fact, it was not Catherine's idea to eat the Demon King, but the will of the Vault Keeper to stay behind when she left Catherine. These suggestions also include the use of bulls-eye demons to temporarily control the mind of the demon king.

For a long time, Catherine didn't have much to do with how to use the bullseye demon effectively. The Guardian was well-informed, and he read Catherine's past experiences and found that the female mage had great potential in the soul realm.

Therefore, the library keeper made a temporary decision and asked the female mage to try to subdue the demon king. Even if Catherine can't do it, it doesn't matter. Anyway, the library keeper will close this crystal ball, and will never let the demon king leave freely.

But things went surprisingly well. Catherine didn't expect the bull's-eyed demon to work so well either. Now she clenched her fists and said to the head of the demon king who was glaring at her on the meditation cushion, "It turns out that you are not so difficult to deal with, what a pleasant process." ”

The mage walked over, picked up the Demon King's ear, and carried him like a handbag. The Demon King snorted twice, he had a word of suffering. The bull's-eye demon is not difficult to deal with, but it just so happens that the demon king devours the immortal bird, leaving hidden dangers in his body. To get rid of the bewilderment of the bull's-eye demon, it is inevitable that you will not be able to suppress the will of the immortal bird.

The will of the immortal bird is a big problem in the heart of the demon king, once it breaks through the shackles. The Demon King is in danger of being counterattacked. Of course. The situation is also awkward. The dignified Lord of Hell has only one head left.

"What's the use of you against me. The head of the demon king said, "The keeper has bad intentions, and I have come to save you." He made us kill each other. I'm telling you that he closed the world off and definitely had a bad idea. ”

"The Keeper told me. He will sacrifice us to the master of the storehouse. Catherine said disapprovingly, "He's more honest than you, and you're definitely not here to save me." If you want to save me, why do you want to come into my world? ”

Catherine walked out of the library with the Demon King in her hand, crossed the street, and came to the tallest irregular cylindrical building in the Royal Academy. The building is divided into two parts, the lower part is three or four stories high, and the higher it goes, the thicker the exterior of the whole building becomes. In the middle of it is a large hexagonal platform with bulging layers. There is also a tall obelisk on the platform.

Catherine pointed to the red flame pattern on the wall of the building and said, "This is Master Griggs' alchemy research institute. From the day I entered the Academy, I was curious about what Master Griggs' alchemy room was like. I've only climbed up to the hexagonal platform of the Alchemy Research Institute before, but I've never been there. ”

The female mage walked into the Alchemy Research Institute with a rabbit's head as if she were visiting a museum. The alchemy research institute was filled with a pungent strange smell, and every few steps. The taste will change, and the feeling will definitely be in your own purgatory. The aisle walls of the Alchemy Research Institute were littered with colorful scars, burning, corroded, weathered, soaked, and rotting...... And so on, like a prisoner who has been humiliated and tortured.

Strangely there is not a single door in the building, and at the end of the wide hallway is a wooden staircase leading upstairs. The wooden staircase is old and black, but it is also very sturdy, and the ground is like a stone step when stepped on.

"The first three months of work for every student admitted to the Alchemy Research Institute was to refine petrochemical potions for wood. The mage explained with interest, "All the building materials in this building are said to have been corrupted, and they will not collapse unless they are regularly poured with various alchemical potions to strengthen their hardness. Therefore, the students of the Alchemy Research Institute are the hardest, and each of them has to refine various basic potions with a fixed amount every day. The remaining time can be used for study and research. ”

Catherine made her way to the second floor, where there was still no door, but two different stairs led to the top.

"Every time I come, someone leads me, and every time I take a different path. Catherine walked up the stairs to the right, "It seems that only if you walk completely correctly will you be able to reach the door that leads to Master Griggs' alchemy." ”

Catherine ascended to the third floor, where four stairs appeared. The female mage stood in the middle of the floor, hesitating. At this time, the Demon King said impatiently: "It's useless for you to go, since you haven't gone to the top, there won't be any alchemy room at all." You can't make something you don't remember here. ”

Catherine nodded, and picked a random path and walked up. Eight staircases appeared on the fourth floor, and Catherine said, "We're about to get to the platform, from where we can go to other institutes." ”

The demon king said, "What the hell are you doing?

"I miss my school days," Catherine said. I've been at the Royal Academy for eleven years, and I haven't been to many places. ”

Catherine continued to walk up, and she finally landed on the hexagonal platform. This platform is full of staircase exits, and you need to go around and around constantly while walking around the platform.

The mage walked around the platform, but found no gate to enter the middle obelisk, and sure enough, she could only go up from the inside.
