Outside the Hidden Treasure Vault
First Madam Salaena and Guardian Nyxarion were enjoying their tea time. The serene atmosphere of their break was interrupted by Madam Salaena's worried tone.
"Senior, why hasn't he come out yet?" she asked, concern evident in her voice.
Guardian Nyxarion glanced at the dark cave entrance, then responded calmly, "The boy might be taking his time. He will come out eventually by the end of the day."
First Madam Salaena relaxed a little after hearing his reassuring words.
Inside the Hidden Treasure Vault
Leon slowly opened his eyes, feeling slightly refreshed. The first thing he saw was the huge pillar. As he gathered his bearings, he remembered the moment he had lost consciousness.
"You're awake, little boy," Spirit Alice's voice called from behind him.
Leon, still seated on the ground, looked back at her with a smile. "Now can you accept me as your master?"
Spirit Alice's mischievous smile hinted at more than a simple agreement. "Yes, but first, check the contents of the pouch. You'll be surprised, little boy."
"I'm not a little boy," Leon retorted as he began to open the small pouch.
Inside the pouch, he found three items: a silver ring, a large old leather map, and the dragon scale.
"What are these?" Leon asked, curiosity lighting up his face.
Alice explained with a smile, starting with the dragon scale. "This is a dragon scale. It wasn't an item in the vault but a component used to create the hidden space. You can take it since it has no purpose here now."
Leon took the dragon scale, examining it with great interest. He had always felt that this dragon scale was more significant than just a mere component. Even in this world, the word "dragon" held a noble connotation.
Next, Spirit Alice pointed at the ancient map. "This is a treasure map made from a 10,000-year-old Frost Whale. I don't know where it leads. You'll have to discover that on your own."
Leon held the treasure map, immediately struck by its coldness. After carefully examining it, he set it aside, not understanding its exact purpose.
Finally, Alice pointed to the silver ring. "This is a Celestial Ring. There are only ten of these in the entire world. Its basic function is to act as a storage device, but it can also store living beings."
"Just one of these treasures is enough to cause all of Magonia to be washed in blood and war. I've made a huge profit this time," Leon thought, feeling both excitement and trepidation.
Leon quickly collected his thoughts and asked, "How am I going to take you out of here?"
"Oh, you still remember me. I thought you'd forgotten about me after seeing these treasures," Spirit Alice teased with a playful smile.
Leon shook his head, smiling back. "I won't forget about you."
"Now, tell me how to take you away from here. I can't stay long; Mother will be waiting for me outside," Leon asked seriously.
Spirit Alice pointed at the Celestial Ring. "Drop your blood on the ring to make a blood pact. The ring will then recognize you as its owner. You can store me and these items inside it. The ring will also be invisible to everyone except you."
Leon nodded and bit his finger, letting a drop of blood fall onto the silver ring. The drop of blood suspended in the air and split into two portions. One portion was absorbed by the silver ring, while the other was absorbed by Spirit Alice.
The silver ring emitted a faint hum as it acknowledged its new master. Simultaneously, Spirit Alice's body seemed to solidify, appearing more energetic and vibrant.
"What was that?" Leon asked, feeling a strange new connection to Spirit Alice.
Alice had a mischievous smile on her face. Her small frame suddenly began to expand, and her clothes disintegrated, leaving only her transparent, crystal-clear body for Leon's eyes to feast upon.
Leon's mouth hung open, and saliva unconsciously trickled out as he became mesmerized by Spirit Alice's striking beauty.
Alice's body stretched to seven feet tall, her slim, conical waist emphasizing her long, slender legs, giving her an incredibly alluring appearance. Most captivating of all were her perfectly proportioned breasts, with beautiful, pointed red nipples that stood out magnificently.
Alice's face seemed to be sculpted from jade, her long, pale golden hair cascading down her back, and her golden eyes giving her the appearance of a goddess descended to the mortal world.
"She's definitely a femme fatale. It's a good thing my body hasn't matured yet, or this would be incredibly embarrassing," Leon thought, quickly wiping away the saliva and saying, "You pervert, put some clothes on!" However, his eyes refused to leave her most intimate areas.
Alice giggled, her voice playful as pale golden clothes materialized on her body. "You're the little pervert here," she teased.
Leon composed himself and asked seriously, "What happened just now? Why did you change so much?"
Alice smiled and said, "My name is Alice GoldenStar. I am not an artifact spirit but a Soul Spirit born on an ancient battlefield. I accompanied the founding ancestor and sealed myself as an artifact spirit. Now the seal is undone due to the blood soul contact between us."
Alice leaned closer, her breath warm against Leon's ear as she whispered seductively, "I can do anything you order, master. Would you like to see my 'big rabbits'?" With a playful tug, she revealed the stunning cleavage between her breasts, offering Leon a provocative view.
Leon swallowed hard and quickly replied, "Stop acting like a pervert. As your master, I command you to behave yourself."
"As you wish, master," Alice responded sultrily, though a mischievous glint remained in her eyes.
"I must be careful of this succubus in the future. But her body is really something. It's a pity she's a spirit," Leon thought, his mind wandering despite his best efforts to stay focused.
"Master, I selected two useful items from the treasure vault," Alice announced, presenting two treasures in her hands.
"Can I still take treasures?" Leon asked, his face flushing with innocent excitement.
"Yes, my little master. The previous treasures were not part of the treasury. So you can still take these two," Alice replied with a smile.
Leon was overjoyed. He examined the two strange items with great interest. One was a large cloak, and the other was a sizable piece of wood.
"What are these, Alice?" Leon asked curiously.
Alice smiled and explained, "This is the Colourless Cloak. Its primary function is to conceal one's cultivation, and no attacks below the Archmage level can harm you."
"That's very useful," Leon nodded appreciatively.
"This," Alice continued, holding up the wood, "is a piece of wood from a 10,000-year-old elemental tree. It's an excellent material for crafting your magic wand."
"A 10,000-year-old elemental tree wood. It's perfect for me! Now I can conduct all my experiments," Leon thought happily as he eagerly took the items.
"Alright, let's leave the treasure vault," Alice said, a hint of excitement in her voice.
Leon asked worriedly, "If you leave with me, what will happen to the treasure vault artifact, and how will you come out with me?"
Alice smiled at his concern. She transformed into a golden light and shot towards Leon's forehead.
Leon was momentarily stunned by Alice's actions. Soon, he heard her voice in his head.
"Master, I am a Soul Spirit born from the remnants of the dead. I can enter your body and hide from everyone. I can also communicate with you telepathically," Alice explained.
Leon's worries dissipated quickly. He took the two treasures and placed the Celestial Ring on his finger. He stored the map and dragon scale inside the ring, knowing it was invisible to outsiders—a perfect hiding place for his treasures.
"Now, let's get out of here," Leon said with a smile, thrilled with his gains from the treasure vault.
He swiftly walked towards the exit, feeling exhilarated by his newfound possessions.
