The Immortal Physician's Transmigration: Miraculous Rejuvenation

Ye Yuanchen, Mu Wanyue, and Lu Zixuan stood at the entrance of the ancient ruins, gazing at the stone gate that emitted a faint light, their hearts filled with both anticipation and a touch of awe. The stone gate was covered with ancient and mysterious runes, which flickered with a faint light, as if telling the story of past glory and vicissitudes.

Ye Yuanchen stepped forward first, extending his hand and slowly channeling his spiritual energy into the runes on the stone door. As the energy flowed in, the runes' light intensified, and a deep rumbling sound emanated from within the stone door, as if some mechanism had been triggered. Then, the stone door slowly opened, releasing an ancient and mysterious aura.

The three cautiously stepped into the ruins, where they found themselves in a long passage. The walls on either side of the passage were inlaid with glowing gems, illuminating the path ahead. They moved slowly along the passage, warily observing their surroundings.

Suddenly, a soft rustling sound came from ahead. Ye Yuanchen gestured for Mu Wanyue and Lu Zixuan to stop, and he focused his spiritual sense to investigate. He saw a group of spider-like demonic beasts surging in from all directions. These spider-like demonic beasts were covered in sharp thorns, and their eyes flashed with an eerie red light.

"Be careful, it's a thorny venomous spider! Their venom is highly poisonous," Ye Yuanchen warned in a low voice.

Having said that, he quickly formed hand seals and chanted incantations. A spiritual energy shield instantly enveloped the three of them, blocking the swarming thorny spiders. Mu Wanyue drew a supple whip from her waist; empowered by her spiritual energy, the whip danced like a nimble dragon, lashing away any approaching spiders. Lu Zixuan swiftly set up a defensive array on the ground. Within the array, spiritual energy flowed, forming sharp beams of light that instantly shattered any spider that touched them.

However, the spiky spiders were numerous, surging in relentlessly, seemingly endless. Ye Yuanchen knew this couldn't continue, so he decided to take the initiative. He concentrated his spiritual energy in his feet and charged into the spider swarm like lightning. His hands became blurry, each swing accurately striking a spider's vital points, killing it instantly.

With the three working together, they finally repelled the swarm of thorny spiders. They continued along the passage and arrived at a vast hall. In the center of the hall stood a circular stone platform, upon which rested a crystal ball radiating a seven-colored light. Something seemed to be slowly flowing within the crystal ball, emanating a powerful attraction.

Ye Yuanchen approached the crystal ball, and his spiritual sense detected an extremely pure spiritual energy within it, unlike anything he had encountered before. He tried to investigate further, but discovered a powerful restriction surrounding the crystal ball.

Just as Ye Yuanchen was studying how to break the restriction, Mu Wanyue discovered some ancient murals in a corner of the hall. The murals depicted a group of immortal-like figures performing a mysterious ritual, surrounding a huge energy vortex, seemingly sealing away some powerful being.

"Yuan Chen, come and look at these murals! They seem to hide some important information," Mu Wanyue called out.

Ye Yuanchen approached the mural and began to examine it closely. The more he looked, the more alarmed he became. Judging from the content of the mural, this ruin was once a place where immortals in ancient times sealed away evil forces, and the crystal ball before him might be the key to that seal. If the seal were accidentally triggered, releasing the evil power, the consequences would be unimaginable.

"We must proceed with caution; this crystal ball must not be moved," Ye Yuanchen said solemnly.

However, Lu Zixuan noticed something strange at this moment. He saw that the restrictions on the crystal ball seemed to be gradually weakening, as if an invisible force was impacting the restrictions from the inside.

"Oh no, this seal might be loosening. Did our battle just now trigger some kind of mechanism?" Lu Zixuan said anxiously.

Ye Yuanchen's heart tightened. He tried again to reinforce the restriction with his spiritual power, but found that his strength was like a drop in the ocean, unable to stop the restriction from collapsing. With a flash of dazzling light, the restriction on the crystal ball shattered completely, and a powerful dark force surged out from within the crystal ball.

This dark power quickly spread throughout the hall, transforming into countless black, ghostly monsters that lunged at the three of them, baring their fangs and claws. Ye Yuanchen sensed the evil aura emanating from these monsters and knew that this would be an extremely difficult battle.

He took a deep breath, maximizing his spiritual power. He unleashed the strongest immortal technique he had learned in the Immortal Abode, his hands flashing as golden arcs of spiritual energy slashed towards the dark phantoms. Mu Wanyue and Lu Zixuan also went all out. Mu Wanyue channeled her spiritual power into her long whip, transforming it into a blade of light that weaved through the horde of dark phantoms, causing them to vanish wherever it went. Lu Zixuan, meanwhile, set up a large killing array within the hall. This array, combined with Ye Yuanchen's immortal technique, created a powerful storm of spiritual energy, temporarily suppressing the dark phantoms.

However, the dark power seemed inexhaustible, and as time passed, the three gradually felt overwhelmed. Ye Yuanchen realized that if things continued this way, they would eventually be devoured by the dark power. Suddenly, a thought flashed through his mind; he remembered the method for purifying evil power that he had seen in the Immortal Abode.

"Wanyue, Zixuan, I have a plan. Let's gather our spiritual energy together and try to purify these dark forces," Ye Yuanchen shouted.

Mu Wanyue and Lu Zixuan unhesitatingly transferred their spiritual power to Ye Yuanchen. Ye Yuanchen transformed the gathered spiritual power into a pure purifying force, which he then infused into the horde of dark phantoms. Under the influence of this purifying force, the dark phantoms emitted painful howls, their bodies gradually becoming transparent before finally vanishing into nothingness.

As the dark phantoms dissipated, the dark power within the hall also gradually dissipated. Ye Yuanchen and his two companions collapsed wearily onto the ground; they had just experienced a life-or-death battle and had exhausted a great deal of their spiritual energy.

Just as they were resting, a voice suddenly came from inside the crystal ball: "Thank you, brave adventurers. I am a remnant soul left behind by an ancient immortal, and I have been guarding this seal. Now the seal has loosened, and evil power has leaked out. Fortunately, you stopped it in time and purified it. As a reward for you, I will bestow upon you a precious gift."

With that, a beam of light shot out from the crystal ball, entering the bodies of Ye Yuanchen, Mu Wanyue, and Lu Zixuan respectively. Ye Yuanchen felt a powerful force flowing through his body, further enhancing his cultivation realm. Simultaneously, his understanding of the fusion of cultivation and medicine deepened. Mu Wanyue's female cultivation technique was perfected, greatly increasing her strength and granting her a new auxiliary cultivation method to better assist Ye Yuanchen in treating patients. Lu Zixuan obtained a more advanced array formation manual; the arrays within this manual possessed immense power, sufficient to repel powerful external enemies.

After accepting the gift, Ye Yuanchen and his companions expressed their gratitude to the ancient immortal. They decided to leave the ruins and bury its secrets forever in their hearts.

When they emerged from the ruins, they discovered that the outside world had changed. Due to the leakage of dark power from within the ruins, strange phenomena began to appear in some of the nearby mountains and forests; some ordinary wild animals became unusually ferocious and even began attacking nearby villages.

Ye Yuanchen realized that they had to take action to stop the disaster from spreading. He led Mu Wanyue and Lu Zixuan to a nearby village, where they used their magical healing skills to help the villagers defend against wild beasts and treat the injured.

During this process, Ye Yuanchen discovered that the reason these beasts had become so ferocious was because they had been corrupted by dark forces. He decided to venture deep into the mountains to find the source of the dark forces and completely purify them.

They traversed the mountains and forests, finally finding a place where the dark power was most concentrated. It was a bottomless valley, filled with black mist, from which eerie lights flickered from time to time.

Without hesitation, Ye Yuanchen jumped into the valley, with Mu Wanyue and Lu Zixuan following closely behind. At the bottom of the valley, they discovered a huge black crystal, which emitted a strong dark aura. It was the dark power it released that was corroding everything around it.

Ye Yuanchen once again used his purification magic, continuously pouring his spiritual power into the black crystal. Mu Wanyue and Lu Zixuan protected him from the side, and after a difficult effort, they finally completely purified the dark power within the black crystal.

As the dark forces were purified, the nearby mountains and forests gradually returned to peace, and the wild beasts returned to normal. Ye Yuanchen and his companions successfully averted the crisis, and their reputation spread even further throughout the region.

However, they also know that in this world where immortals and mortals coexist, many more unknown dangers and challenges await them. They will continue their journey, constantly improving their strength, and using their immortal arts and medical skills to protect the peace and tranquility of the world.
