Robert glanced around, and seeing that no one noticed him, he flashed into the grove, walked quickly to the bottom of the big cedar tree, jumped on the branch, and removed the observation eye that had been installed, and put it in the storage bag.

Hiding in the canopy of the trees for a while, Catherine was never seen, only felt that her legs and feet were sore, and her eyes swept around, only to see a thatched bush not far away, about half a man tall, very dense, hesitated slightly, jumped down the tree, and the figure flickered, and hid in the grass.

He thought about it and felt that it was not safe, so he immediately took out the black robe and put it on, and covered his face with a black cloth, revealing only a pair of eyes, and then activated the advanced stealth technique of the Night Salute Leather Armor, only to see that the space was distorted, and his figure disappeared into the air in an instant.

......

However, Robert did not know that just as he walked out of the firefly house, a bat under the eaves flapped its wings and flew after him towards the academy.

The appearance of this bat is no different from that of a normal bat, except that its eyes are blood-red.

Just as Robert was hiding in the grass, the blood-eyed bat streaked across the night sky and landed silently on the big cedar tree, its feet clinging to a thick branch, and its body hung upside down, quietly observing everything around him.

After a while, I suddenly heard a sound of footsteps in the distance from the west, and a girl wearing silver chain mail and carrying a longbow came from a long bow.

She went straight to the big cedar tree, looked around, didn't see Alex's figure, couldn't help frowning slightly, sat against the tree, looked at the bright moon in the sky, and was stunned.

Suddenly, there was silence between heaven and earth, and occasionally a breeze blew through the groves, making a rustling sound.

Robert lay on the ground and looked at Catherine not far away without blinking, only to feel that time passed extremely slowly, and he had already greeted Alex's relatives in his heart.

Just as Robert was waiting impatiently, he suddenly heard a rush of footsteps in the distance to the east, and turned his head to see Alex appear in the woods, hurrying and panting.

Catherine's sword was overjoyed, she stood up, beckoned to him, her face was full of joy, and when Alex ran under the big cedar tree, she took out a handkerchief, helped him wipe the sweat from his forehead, and asked in a low voice, "Why has it been so long?"

Seeing her helping her wipe her sweat, Alex only felt the indescribable warmth and sweetness in her heart, and said breathlessly, "My old man...... My old man...... Yes...... I fainted after a few cups, but the key ...... Key...... Let me...... I searched for a long time......"

When Catherine heard this, she suddenly chuckled in her heart, and with a worried look on her face, she hurriedly asked, "Did you find it?"

Alex nodded, made an "OK" gesture, and said triumphantly as his breathing became more even, "Of course...... Of course I did, my old man actually hid the key in the safe, and it took me a lot of effort to get it!"

Catherine stretched out her hand to take it, frowning slightly, seeing that the magnifying glass was the size of a palm, mediocre, I really didn't know what it did, and when I got to the front of me, I saw that the world was bright, like day, and suddenly smiled, put the magnifying glass into the storage bag, and said: "Without further ado, go to the secret room now!"

Alex nodded, and the two turned around and walked out of the woods.

When the two of them were far away, Robert stood up, flashed out of the grass, and quietly followed them, always about ten meters away from them.

After seeing the three of them walking away, the blood-eyed bat fluttered its wings and followed Alex and Catherine in mid-air, and in the blink of an eye, it disappeared into the darkness.

Alex and Catherine only picked up the deserted path, and after a short time, they came to a deserted wood, with branches and foliage covering the sky. It is less than 100 meters away from the magic tower, and the dome of the magic tower can be faintly seen between the trees.

Suddenly, Catherine stopped, took two sets of black robes from the storage bag, and handed Alex one. The two hurriedly changed into black robes.

When Robert saw it, he almost spurted out a mouthful of old blood, only to see that the two of them were shrouded in black robes, with a black cloth covering their faces, and only a pair of eyes were exposed, which were exactly the same as their own outfits.

At this moment, Catherine stretched out her hand and pointed to the woods, and whispered, "You put a fire and give the academy a twist!"

Alex suddenly understood, recited the incantation, and stretched out his fingers.

I could only hear the sound of thumping, and seven or eight fireballs had hit the surrounding trees.

The woods were engulfed in flames in an instant, and the flames were so dazzling that they lit up almost half of the sky, and the smoke was billowing and gradually spreading.

Alex was quite proud under the sword, a cruel smile appeared on the corner of his mouth, took Catherine's hand, and rushed towards the magic tower.

Robert and the Blood-Eyed Bat followed.

A moment later, there was a faint scream in the distance.

"Ah~~, there's a fire over there~~!"

"It's the magic tower that's on fire!"

"Hurry up and put out the fire~~!"

......

Amid the exclamations of the crowd, teachers and students who were closer to the woods rushed to the forest one after another, some casting water magic, and some calling for clear water...... It's just that the fire is too fierce, and second, it is a kilometer away from the river, and for a while, the fire is not only not decreasing, but is getting bigger and bigger.

The basement of the magic tower is where the secret room is located, and the entrance is in the back garden, where two teachers are guarded all year round, and when they see the fire in the woods, the two teachers are taken aback, talk a few words, and then rush away.

At the moment when the two teachers ran out of the magic tower, the figures flickered in the darkness, and Alex and Catherine silently dodged into the magic tower, with Robert and the Blood-Eyed Bat following them.

Walk through the winding aisles into the back garden of the Magic Tower, and then around a flower bed and a rockery to the entrance to the secret room.

The entrance to the chamber, located in the back garden on the first floor of the Magic Tower, was a small and inconspicuous stone house, with a narrow wooden door that could only accommodate one person, and the paint on it was mottled in many places.

Robert followed Catherine and Alex to the back garden, where he quietly hid in the shadow of a large tree, moving and watching the two.

The blood-eyed bat also flew to the tree and hung upside down under the branches, its eyes shining with golden light.

Catherine and Alex were overjoyed to see that there was no one in front of the door.

Alex approached, chanted a spell, and cast a "Trap Detection Technique", pointing at the small door, and a dazzling white light shot on it.

I saw a flash of magic on the small door, and a magic trap suddenly appeared.

Catherine was prepared, took out a bottle of blue potion from the storage bag, unscrewed the cap, and with a loud sound, splashed the blue potion in the bottle on the magic trap.

As soon as the magic trap came into contact with the blue potion, it instantly dimmed and disappeared in the blink of an eye.

Under the sword of the two, their hearts were suddenly overjoyed, they glanced at each other, and nodded at the same time.

Only a creaking sound was heard, Catherine gently pushed the door open, and in the darkness, she saw a hazy staircase leading straight down, and immediately took out a piece of moonstone from the storage bag, emitting a faint white light.

Catherine didn't hesitate any longer, and walked up the stairs to the basement, where Alex closed the door and followed closely.

At the moment when the two closed the door, the space rippled slightly, Robert walked slowly to the small door, listened attentively, only heard the footsteps of the two gradually faded away, took a deep breath, creaked, gently pushed open the small door, only to see that it was pitch black, and a hazy white light could be seen in the distance under the stairs, knowing that it was the moonstone used by Alex and the two to illuminate, and followed up the stairs silently.

When Robert entered the small door, the Blood-Eyed Bat was still hanging upside down in a dark corner of the back garden, moving and watching the movement around him, and did not seem to be in a hurry to enter the secret room.

After a short time, Catherine and Alex had gone down all the stairs when they saw a few candles lit on the wall, glowing yellowish, and the place where they were found was a hand.

Suddenly, there was a low roar of a beast from the front, and although the two of them had been prepared, they couldn't help but shiver at the spirit, and followed the sound to see that there was a door at the end, and in front of the door there was a three-headed dog of hell.

This three-headed dog of hell belongs to the fifth-level demonic beast, the size of a calf, the whole body is covered with black hair like steel needles, but there are three dog heads on one body, the fangs are dense, saliva drips fall to the ground, corroding the granite ground into small pits, and an arm-thick iron chain is tied to the neck.

The three-headed dog of hell smelled Alex and Catherine, and felt very strange, and stood up at once, with a fierce look in his eyes, and roared repeatedly, and the chain around his neck rattled, and it looked as if he was about to break the chain and pounce on him.

Catherine didn't dare to slack off, and hurriedly took out the manticore's tail and threw it over.

There was only a snapping sound, and the tail of the manticore fell to the ground in front of the three-headed dog of Hell.

Under the sword of the three-headed dog of hell, he was slightly stunned, leaned his nose over and sniffed it, and suddenly his eyes shot a golden light, and one of the heads bit the tail of the manticore, "Click~~" and chewed it.

The other two heads were not far behind, competing with the one just now.

Suddenly, the low roaring and biting sound in the aisle was endless, and the three heads rushed together.

After a while, the three-headed dog of hell had eaten the whole tail of the manticore, and still unsatisfied, licked his tongue, and looked at Catherine with a clear expression in his eyes: "Is there another one?"

Catherine was shocked when she saw that there was no sign of poisoning after eating it, and she didn't know what to do for a while, so she was stunned on the spot.
