The Immortal Physician's Transmigration: Miraculous Rejuvenation

The peaceful days didn't last long. Just as Ye Yuanchen and the others were immersed in the increased strength brought by the inheritance and the prosperity of the Spirit Realm, a series of strange events suddenly occurred in the Three Realms. Some places were inexplicably shrouded in a dark aura. Although it wasn't as intense as last time, it was ever-present and difficult to dispel.

Some spiritual veins in the cultivation world began to become unstable, their spiritual energy fluctuating wildly and depleting at times, causing many disciples to suffer from demonic possession during their cultivation. Some spiritual plants in the spirit realm also withered without warning, emitting a faint dark aura, as if corrupted by some evil force. Strange disasters also occurred in the mortal realm, with floods, droughts, and plagues raging in turn, causing immense suffering to the people.

Upon hearing this news, Ye Yuanchen and the others felt a sense of foreboding. "This dark aura, though seemingly weak, is extremely persistent and certainly not accidental. Could it be that the forces of darkness have returned?" Ye Yuanchen frowned, his eyes revealing worry and vigilance.

Mu Wanyue said with a solemn expression, "Regardless of whether it is a dark force or not, we must find out the cause as soon as possible and not let the situation continue to deteriorate."

Lu Zixuan took out various detection artifacts and began to carefully study the source and characteristics of these dark auras. "These dark auras are different from the previous ones. They seem to be more hidden and elusive, and they contain a peculiar fluctuation that I have never seen before."

Bai Youruo played the Lingxu Lingyin Flute, attempting to dispel the dark aura with the power of the flute's sound, but the effect was minimal. "This dark aura seems to have come to life, constantly resisting my flute's sound."

To investigate this matter thoroughly, Ye Yuanchen and the others decided to split into three groups. Ye Yuanchen went to the cultivation world to explore the cause of the abnormal spiritual veins; Mu Wanyue stayed in the spirit world to continue observing the changes in spiritual plants; Lu Zixuan and Bai Youruo went to the mortal world to help the people resist disasters and search for clues about the dark aura.

Ye Yuanchen arrived at a spiritual vein in the cultivation world. The sky was shrouded in a layer of black mist, and the surrounding land was cracked and parched, emitting a pungent odor. He cautiously approached the vein, his Spirit Void Holy Sword emitting a golden light in an attempt to dispel the darkness. However, the moment he touched the vein, a powerful surge of dark energy erupted, forcing him back several steps.

"This dark power is actually hidden within the spiritual veins. Who could be behind this?" Ye Yuanchen was filled with doubt and anger. He unleashed the "Spirit Realm Chaos Suppressing God Technique," engaging in a fierce battle with the dark power. During the battle, he discovered that this dark power seemed to be constantly absorbing the spiritual energy of the spiritual veins, strengthening itself.

Mu Wanyue wandered throughout the spirit realm, examining the withered spiritual plants. She discovered that the roots of these plants were entangled in black threads, which, like parasites, continuously drained the plants' life force. She wielded her Spirit Whip, attempting to sever the black threads, but they were incredibly tough and difficult to cut.

While helping the people in the mortal realm with disaster relief, Lu Zixuan and Bai Youruo were also secretly investigating the source of the dark aura. They discovered that whenever a disaster occurred, mysterious black shadows would appear. These shadows moved swiftly and would disappear without a trace once discovered.

After some investigation, Ye Yuanchen and his companions finally discovered that behind these bizarre events was a mysterious organization manipulating things in the shadows. This organization seemed to be collecting dark forces from the Three Realms and attempting to use these forces to break an ancient seal, releasing an even more powerful evil force.

"We absolutely cannot let their conspiracy succeed!" Ye Yuanchen said angrily. He decided to join forces with Mu Wanyue, Lu Zixuan, Bai Youruo, and the Three Realms Alliance to fight against this mysterious organization, stop their evil plans, and save the Three Realms from danger once again.
