The setting sun dyed the sky blood red and illuminated the ruins of the ancient city of Zifara. Alexander and Adrian stood at the foot of the Guardian of Knowledge Tower. The tower was like a silent giant, towering into the clouds, and its surface was covered with flashing runes, which looked particularly mysterious in the afterglow of the sunset.
"This is the residence of the Guardian of Knowledge," Adrian said softly, his eyes full of solemnity, "Be careful, Alexander. This may contain the most dangerous secrets of Zifara."
Alexander nodded and took a deep breath. He could feel the powerful energy emanating from the tower, as if issuing a silent warning to them: "How do we get in?"
Just then, a faint blue light lit up on a stone slab at the bottom of the tower, like a star twinkling in the night sky. Alexander squatted down and observed carefully. It was a complex rune puzzle composed of countless tiny symbols, as if waiting to be solved.
"It seems that this is our ticket," Alexander said. He had never seen such a complex rune structure, as if it contained endless mysteries. "But this rune... I have never seen such a complex structure."
Adrian leaned over to check. He could recognize that these runes belonged to the advanced rune language of Zifara. These runes were not only a puzzle, but also a knowledge test: "This is Zifara's advanced rune language. It is not only a puzzle, but also a knowledge test."
Alexander began to try to solve the puzzle. He gently touched the runes with his fingers, and the runes began to move, forming different combinations, as if performing a silent dance. Suddenly, a picture flashed in his mind-he saw the guardian of knowledge writing these runes, and each stroke contained profound magical principles, as if showing him the power of knowledge.
"I understand," Alexander suddenly realized, as if he had grasped the essence of knowledge, "This is not for us to 'unlock' it, but for us to 'understand' it."
He closed his eyes and let his consciousness resonate with the runes, as if he wanted to integrate his soul into those ancient symbols. Slowly, the runes began to automatically arrange themselves, forming a complete pattern, as if responding to his understanding.
With the last rune in place, the entire tower began to vibrate, as if responding to their arrival. A ray of light shot out from the top of the tower, enveloping Alexander and Adrian, like a bridge to an unknown world.
"Well done," an ethereal voice sounded, full of wisdom and power, "You have demonstrated the wisdom of understanding. Welcome to the Hall of Knowledge."
After the light dissipated, they found themselves inside the tower, as if they had entered a world full of magic. Surrounded by countless suspended books and scrolls, knowledge flowed in the air in the form of entities, as if showing them the crystallization of human wisdom.
"This is incredible," Alexander exclaimed. He reached out and touched a stream of knowledge passing by. Instantly, a large amount of information poured into his mind, making it difficult for him to bear it for a while.
Adrian pulled him in time. He could feel the powerful force contained in the knowledge flow, as if he would be swallowed up if he was not careful: "Be careful, the knowledge here is too concentrated. We need to find the guardian of knowledge, she can give us the answer."
They began to explore the tower, and each floor was full of knowledge in different fields. Physics, chemistry, biology, philosophy... All the crystallizations of human wisdom gathered here, like a treasure house of knowledge.
In the center of the tower, they found a huge spherical device, where countless knowledge streams converged, like a huge heart, beating constantly.
"What is this?" Alexander asked, he could feel the powerful energy emanating from the device.
"Knowledge core," Adrian explained, he could feel the extraordinaryness of this device, "the source of all knowledge in Qifala. But it looks... not very stable."
Indeed, the knowledge core is fluctuating violently, sometimes expanding, sometimes contracting, as if experiencing a huge energy storm.
Suddenly, a holographic image appeared in front of the core. It was a woman in a robe, her eyes full of wisdom and worry, as if she was watching them.
"Welcome, seekers," she said, with a hint of fatigue in her voice, "I am Isabella, the guardian of knowledge. Although my body has disappeared, my consciousness still guards this tower."
Alexander took a step forward. He could feel the powerful power of this guardian of knowledge: "Lady Isabella, we are here to seek the truth. What happened to Zifara? Why was it destroyed?"
Isabella's image sighed, as if recalling the painful past: "That's a sad story, young man. We pursue knowledge, but ignore the responsibility that knowledge brings. We create the ability to travel through time. "Time magic?" Adrian asked in surprise. He could feel the powerful force of time magic, as if it could change the fate of the world. "Is it the one we saw in the scroll?" Isabella nodded: "Yes. We thought we could use it to prevent disasters and create a perfect world. But we were wrong. Interfering with time has terrible consequences. Reality began to collapse, and the vortex you saw was a crack in time and space. " Alexander recalled the scene he saw in the illusion of time, and shuddered. He could feel the terrifying power of the crack in time and space, as if Buddha can devour everything: "So, how did the city survive?"
"We paid a huge price," Isabella said, her voice full of sadness, "We sacrificed the vitality of the entire city to seal the space-time rift. Qifala became the ruins you see, and our consciousness was trapped in this tower, forever guarding this dangerous secret."
Adrian frowned, he could feel the fragility of the seal, as if it would collapse at any time: "But now the crack seems to be unstable again."
Isabella's expression became more worried: "Yes, the seal is weakening. If no action is taken, space-time will be The crack may open again, and this time it will not only be Qifala, but the whole world will be in danger. "
Alexander felt a heavy feeling, and he could feel that the fate of the world was in his hands: "What should we do?"
Isabella's eyes fell on Alexander, as if looking at the hope of the future: "You, young seeker, you have special power flowing in your body. Only you can stabilize the seal again. But it takes great courage and sacrifice. Are you ready to accept this challenge? "
Alexander looked at Adrian, who gave him an encouraging look, and he could feel Adrian's trust in him. He took a deep breath and said firmly: "I'm ready. Tell me what to do. "
Isabella nodded: "Very good. But before that, you need to go through the final trial. Only by truly understanding the essence of knowledge can you control its power. "
As her voice fell, the core of knowledge suddenly burst into a dazzling light, like a star about to explode. Alexander felt that he was attracted by a powerful force and began to integrate into the endless torrent of knowledge, as if to merge himself with knowledge.
"Alexander!" Adrian's voice echoed in the distance, but was soon drowned in the ocean of knowledge.
Alexander knew that he was about to face the most difficult challenge. In this endless river of knowledge, he must find the truth and find a way to save the world. And all this depends on whether he can truly understand the nature and power of knowledge.
