The Immortal Physician's Transmigration: Miraculous Rejuvenation

Ye Yuanchen stood before the hall's main gate, carefully examining the runes and patterns on it, trying to find a way to open it. Mu Wanyue, Lu Zixuan, and Bai Youruo also gathered around, each using their knowledge to analyze the possible hidden information behind these mysterious symbols from different angles.

“These runes seem to be different from any we’ve seen before; the spiritual power they contain is more ancient and obscure.” Ye Yuanchen frowned, and the Spirit Void Holy Sword in his hand trembled slightly, as if it were resonating with the runes on the door.

Lu Zixuan took out some ancient book rubbings from his storage magic treasure and compared them one by one with the runes on the door. "I saw similar symbols in an ancient book, but only some scattered records. These runes seem to be related to an ancient sealing ritual. Perhaps we need to find a specific spiritual energy frequency to activate them in order to open the door."

Mu Wanyue wielded the Spirit Whip, the tip of which gently touched the runes on the door, sensing their energy fluctuations. "I feel there's some kind of interconnected relationship between these runes, like a giant spiritual energy array. Do we need to input spiritual energy in a certain order to break this array and open the door?"

Bai Youruo played the Lingxu Lingyin Flute, its melody echoing before the hall, the sound waves penetrating the doors and entering the hall itself. She closed her eyes, focusing her attention on the information the flute's melody reflected back. "There seems to be a powerful and chaotic force surging within. We must hurry in; something may be about to spiral out of control."

After some discussion, they decided to try following Mu Wanyue's method to find the correspondence between the runes and input spiritual power in a specific order. Ye Yuanchen stood at the forefront, pointing the tip of the Spirit Void Holy Sword at a rune on the door and slowly injecting spiritual power. As the spiritual power was injected, the rune lit up slightly, emitting a faint glow.

Next, based on the energy fluctuations of the runes, Mu Wanyue used the Spirit Whip to guide Ye Yuanchen's spiritual power, transferring it to the next rune. Lu Zixuan monitored the entire process with a spiritual power detector, ensuring the input of spiritual power was stable and accurate. Bai Youruo played the Spirit Flute, using the sound waves to stabilize everyone's minds, while also providing a subtle boost to the transmission of spiritual power.

With their seamless coordination, the runes on the door lit up one by one, their light growing increasingly dazzling. Finally, as the last rune was illuminated, the door emitted a muffled rumble and slowly opened. An ancient yet powerful aura rushed out, causing everyone to shudder slightly.

They cautiously entered the hall, which was spacious and empty inside. The walls were covered with huge murals depicting an earth-shattering war from ancient times. In the scenes, various strange creatures were engaged in a fierce battle with dark forces, and the air was filled with spiritual energy, as if the end of the world had arrived.

In the center of the hall stood a massive stone platform, upon which rested a crystal ball radiating a deep blue light. Around the crystal ball were intricate rings of spiritual energy patterns, which, as if alive, constantly flickered and emitted powerful energy fluctuations in all directions.

"Is this the core of the ruins? This crystal ball seems to contain extremely powerful energy." Ye Yuanchen stared at the crystal ball, a strange unease rising in his heart.

Just as they approached the crystal ball, it suddenly trembled violently, and the surrounding spiritual energy patterns became chaotic. Immediately afterward, a plume of black smoke surged from the crystal ball, quickly spreading and enveloping the entire hall.

"Oh no! This crystal ball seems to have been corrupted by something, and its power is getting out of control!" Lu Zixuan shouted. He quickly set up a defensive array around it in an attempt to block the black smoke from corroding it.

However, the power of the black smoke was extremely strong. The formation was broken through by the black smoke as soon as it was set up. Ye Yuanchen and the others were surrounded by the black smoke and immediately felt an heavy pressure coming towards them. Their bodies felt as if they were being pierced by thousands of steel needles at the same time, and their souls were also severely impacted.

"Everyone be careful, this smoke is poisonous!" Mu Wanyue exclaimed. She waved her Spirit Whip, trying to disperse the surrounding black smoke, but to no avail.

Bai Youruo played the Lingxu Lingyin Flute, and the flute's sound transformed into a powerful purifying force, attempting to cleanse the toxins within the black smoke. However, the black smoke's corrosive speed was too rapid, and the purifying force could not keep up with the rate of erosion.

Despite the excruciating pain, Ye Yuanchen unleashed the "Spirit Realm Chaos Suppressing Divine Technique," gathering spiritual energy around his body to form a protective barrier against the black smoke. Simultaneously, he attempted to touch the crystal ball with the Spirit Void Holy Sword to see if he could find a way to control it.

The moment the Spirit Void Holy Sword touched the crystal ball, a powerful electric current surged from the crystal ball, traveling along the sword and throughout Ye Yuanchen's entire body. Ye Yuanchen felt a numbing sensation throughout his body and almost dropped the sword.

"The power of this crystal ball is too great; we can't force it," Ye Yuanchen shouted. He sheathed his Spirit Void Holy Sword and began to think of other solutions.

In this critical moment, Lu Zixuan suddenly remembered a method for purifying evil forces that he had seen in an ancient book. "Perhaps we can use the power of the five elements to purify the dark power in this crystal ball. I need everyone's help to inject spiritual power into the crystal ball in the order of metal, wood, water, fire, and earth, forming a cycle of the five elements' spiritual power."

Upon hearing this, everyone immediately acted according to Lu Zixuan's instructions. Ye Yuanchen, representing the power of metal, adjusted the spiritual power of the Lingxu Holy Sword to the metal element and then injected it into the crystal ball. Mu Wanyue, representing the power of wood, wielded the Lingxu Spirit Whip, injecting wood-attribute spiritual power into the crystal ball. Lu Zixuan, representing the power of water, used an array to guide water-attribute spiritual power into the crystal ball. Bai Youruo, representing the power of fire, played the Lingxu Spirit Flute, transmitting fire-attribute spiritual power into the crystal ball through the flute's sound.

With everyone's combined efforts, a cycle of the five elements gradually formed around the crystal ball. The black smoke inside the crystal ball began to slowly dissipate, and the eerie blue light gradually stabilized.

However, just as they were about to successfully purify the crystal ball, a powerful suction force suddenly emanated from it, pulling Ye Yuanchen and the others towards it. They had no time to resist and were sucked into the crystal ball.

Inside the crystal ball was a strange space, filled with multicolored light that twisted and spun like living things. In the center of this space was a colossal black figure, surrounded by a thick aura of darkness. Its eyes, like two black suns, emitted a terrifying light.

"Welcome to my world, you insignificant ants!" The black figure let out a low, evil laugh that echoed through the space, sending chills down one's spine.

Ye Yuanchen and the others watched the black figure warily, knowing that an even more severe test was about to begin.
