The Immortal Physician's Transmigration: Miraculous Rejuvenation

Ye Yuanchen and the others gripped the Key to the Spirit Realm tightly, following the guidance of the information flooding their minds, and found the entrance to a mysterious space in a remote valley within the Spirit Realm. The entrance emitted a chilling light, and the surrounding space was distorted and deformed, resembling the maw of a colossal beast leading to an unknown world, faintly radiating a terrifying aura.

"This mysterious space looks dangerous, everyone must be careful." Ye Yuanchen gripped the Spirit Void Holy Sword and stepped into the twisted entrance first.

Mu Wanyue, Lu Zixuan, and Bai Youruo followed closely behind. The moment they stepped into the mysterious space, a powerful dark force rushed towards them, completely different from what they had felt in the Spirit Realm. The darkness here was purer and more intense, as if it could freeze one's soul.

"This dark power seems stronger than before; we can't afford to be scattered," Mu Wanyue said warily, her Spirit Void Whip trembling slightly, ready to strike at any moment.

Lu Zixuan quickly set up a spiritual energy detection array around him, but the array was immediately shaken by a surge of dark power. "The dark power here has a strong suppressive effect on our array, and my detection is severely limited," he said, frowning, his forehead covered in sweat.

Bai Youruo played the Lingxu Lingyin Flute, the sound struggling to travel through the darkness, attempting to dispel some of the dark power, but with little effect. "This dark power seems to be constantly eroding my flute music; I need stronger power to fight against it."

Looking at the endless darkness around them, Ye Yuanchen said, "No matter what, let's explore forward first. Perhaps we can find the core of the dark power or some clues."

They cautiously moved through the mysterious space, the ground beneath their feet uneven, with black spikes occasionally emerging from the ground, nearly injuring them. Suddenly, a group of dark figures surged out of the darkness, these figures were ghostly and incredibly fast, and instantly surrounded them.

Ye Yuanchen unleashed the "Spirit Realm Chaos Suppressing God Technique," his Spirit Void Holy Sword radiating golden light in an attempt to dispel the shadows. Mu Wanyue wielded the Spirit Void Whip, its pink trajectories tracing patterns in the air as it intertwined with the shadows. Lu Zixuan continuously adjusted the formation during the battle, trying to trap the shadows within it. Bai Youruo played the Spirit Void Spirit Sound Flute, its notes transforming into sonic blades that sliced ​​through the shadows' bodies.

However, these shadowy figures seemed endless, and they would quickly reform after being scattered. In the fierce battle, everyone gradually felt exhausted, and their spiritual energy was constantly being depleted.

"This can't go on. We need to find their weakness," Ye Yuanchen shouted, as he parried the attacks from the shadowy figures while carefully observing their patterns of movement.

After some observation, Ye Yuanchen discovered that these dark figures would briefly gather together during their attacks, forming a black core. "Everyone, focus your attacks on their core!" Ye Yuanchen shouted.

Upon hearing this, the group adjusted their tactics, focusing their attacks on the core of the shadowy figures. Under their combined assault, the core of the shadowy figures began to crumble, and the figures gradually dissipated.

"We've finally dealt with these guys, but this is just the beginning. There are definitely more dangerous things to come," Mu Wanyue said, panting heavily.

They continued onward, and soon came to a wide, dark river. Black liquid flowed in the river, emitting a pungent odor, like the blood of a demon.

"How do we cross this river? It looks dangerous." Lu Zixuan looked at the dark river with a troubled expression.

Ye Yuanchen pondered for a moment and said, "I will try to build a bridge with my spiritual power first, and you will protect me from behind."

He concentrated his spiritual power and slowly waved his hands, causing streams of golden spiritual energy to flow from them, gradually forming a spiritual energy bridge over the dark river. However, just as the bridge was about to take shape, a massive black wave suddenly surged up from the river, instantly washing away the spiritual energy bridge.

Ye Yuanchen was thrown back several steps by the force of the black wave, a trickle of blood spilling from the corner of his mouth. "The power of this river is too great; my spiritual power cannot contend with it."

Mu Wanyue rushed forward to support Ye Yuanchen, "Yuanchen, are you alright?"

Ye Yuanchen wiped the blood from the corner of his mouth and said, "I'm fine. We need to think of another way."

Bai Youruo looked at the dark river and said, "Perhaps my flute music can try to freeze the surface of this river, allowing us to cross it."

She began to play the Spiritual Flute, the melody growing higher and more intense, a chilling power emanating from it and spreading towards the dark river. Under the influence of the flute's sound, the river's surface gradually began to freeze.

"Quick, let's cross the river now!" Bai Youruo shouted.

The group carefully stepped onto the frozen river, but just as they reached the middle of the river, a crack suddenly appeared in the ice, and black liquid gushed out from the crack, trying to swallow them.

"Not good, let's go!" Ye Yuanchen shouted. He used the "Spirit Realm Flight Technique" to quickly fly away from the river and land on the opposite bank.

As soon as they landed, they heard a deep roar coming from ahead. A huge dark beast appeared before them, its body as large as a mountain, covered in black scales, each scale gleaming with an evil light. Its eyes were like two burning black flames, and its mouth was full of sharp fangs, emitting a nauseating stench.

"What kind of monster is this? It looks so powerful!" Mu Wanyue exclaimed in horror.

Ye Yuanchen looked at the dark behemoth and said, "No matter what it is, we must defeat it in order to move forward."

He charged towards the dark behemoth first, unleashing the strongest move of the "Spirit Realm Chaos Suppressing God Technique." The runes on the Spirit Void Holy Sword shone with dazzling light, and a huge golden blade of light slashed towards the dark behemoth.

Mu Wanyue brandished her Spirit Whip, unleashing the immortal technique "Spirit Dance Illusion Whip Void Break," the whip transforming into countless pink rays of light that coiled towards the dark behemoth. Lu Zixuan set up a "Spirit Void Demon Extermination Array" nearby; once activated, beams of spiritual energy shot towards the dark behemoth. Bai Youruo played the Spirit Void Melody Flute, the music transforming into a powerful soul-shaking force that surged towards the dark behemoth's soul core.

However, the dark behemoth easily withstood their attacks. It swung its massive claws, shattering the golden light blade Ye Yuanchen had unleashed. It also broke free from the entanglement of the spirit whip. The spiritual energy arrows that struck its body only caused its scales to tremble slightly, and the soul impact of the flute's sound failed to cause it any substantial damage.

"This monster's defense is too strong; our attacks are completely ineffective against it," Lu Zixuan said anxiously.

Ye Yuanchen gazed at the dark behemoth, pondering a countermeasure. Suddenly, he thought of the Key to the Spirit Realm. "Perhaps the Key to the Spirit Realm can work on it; after all, it's a sacred relic of the Spirit Realm."

He took out the Key to the Spirit Realm and infused it with his own spiritual power. The Key to the Spirit Realm instantly shone brightly, and a powerful force of spiritual primordial energy shot towards the dark beast. Sensing the threat of this force, the dark beast tried to dodge, but it was too late. The force struck its body, and the dark beast let out a painful roar as cracks began to appear on its body.

"It works! Everyone, keep attacking!" Ye Yuanchen shouted.

Seeing this, everyone unleashed their unique skills once again, launching a fierce attack on the dark behemoth. Under the combined assault of the Key of the Spirit Realm and the group, the dark behemoth finally succumbed, its massive body collapsing with a deafening roar and dissipating into a cloud of black smoke.

"We've finally defeated this monster, let's continue on our way," Ye Yuanchen said. After a short rest, they continued their exploration deeper into the mysterious space, unaware of how many more dangers awaited them.
