The Immortal Physician's Transmigration: Miraculous Rejuvenation

As Ye Yuanchen's sailboat drew closer to the South China Sea Immortal Island, the powerful spiritual energy fluctuations grew increasingly clear, as if the island itself were issuing a warning, inspiring awe. The surrounding seawater also became turbulent, constantly crashing against the hull, seemingly trying to hinder their progress.

"Everyone be careful. The spiritual energy here is chaotic, and there must be many dangers lurking around," Ye Yuanchen said solemnly. He poured his spiritual energy into the hull, stabilizing the sailboat and making it barely stay stable in the waves.

Mu Wanyue stood at the bow of the ship, her gaze fixed firmly on the immortal island, her hand tightly gripping her spirit whip. "No matter what dangers we face, we must obtain the Spirit Source Sacred Fruit for you, to help you break through your bottleneck."

Lu Zixuan silently set up a defensive formation at the stern of the ship to guard against a sudden attack from the sea beasts. "I have never seen the formation aura around this island before. I'm afraid it won't be so easy to break."

The sailboat finally approached the edge of the immortal island, and Ye Yuanchen was the first to leap ashore. The moment he landed, he felt an immense pressure bearing down on him. This pressure didn't come from an external attack, but from the island's own protective barriers. He circulated his spiritual energy, barely resisting the pressure, while simultaneously cautiously observing his surroundings.

Mu Wanyue and Lu Zixuan also came ashore one after another. The three of them stood back to back, forming a defensive formation. The surrounding scenery was very strange. Various strange flowers, plants and trees grew on the island. Some shimmered with light, and some emitted fragrance. However, these flowers, plants and trees seemed to have their own consciousness. When they approached, they swayed slightly, as if they were monitoring them.

"Let's search for the Spirit Source Sacred Fruit first, and try not to trigger the island's restrictions," Ye Yuanchen said in a low voice. He released his spiritual sense and carefully explored the surroundings.

They proceeded slowly along a winding path, carefully avoiding the dangerous-smelling flowers and plants. Suddenly, a deep roar came from the woods ahead, followed by the emergence of a massive, fiery red Qilin beast. The Qilin was engulfed in flames, its eyes filled with ferocity and vigilance.

"This is a Fire Kirin Beast, with extremely strong attack power. Everyone be careful!" Ye Yuanchen shouted. He quickly formed hand seals and shot a stream of ice-type spiritual energy towards the Fire Kirin Beast, attempting to lower its body temperature and weaken its power.

Mu Wanyue brandished her spirit whip, the long whip drawing a graceful arc in the air before wrapping around the Fire Scale Beast's limbs, attempting to restrict its movements. Lu Zixuan, meanwhile, set up a trapping array nearby, with spiritual energy flowing within the array, forming layers of barriers that confined the Fire Scale Beast within.

However, the Fire-Scaled Beast's strength far exceeded their expectations. With a powerful struggle, it broke free from Mu Wanyue's spiritual whip and pounced towards Ye Yuanchen. Ye Yuanchen dodged the Fire-Scaled Beast's attack, and at the same time, a longsword formed from spiritual energy appeared in his hand. He wielded the longsword and engaged in a fierce battle with the Fire-Scaled Beast.

Seeing this, Mu Wanyue and Lu Zixuan both intensified their attacks. Mu Wanyue used a supportive immortal technique, injecting a gentle stream of spiritual energy into Ye Yuanchen's body to enhance his strength and speed. Lu Zixuan, on the other hand, added an attack formation to the trapping array, firing beams of spiritual energy towards the Fire Scale Beast.

With the combined efforts of the three, the Fire Scale Beast gradually showed signs of fatigue. Ye Yuanchen seized the opportunity and unleashed a full-force attack, his longsword piercing straight into the Fire Scale Beast's vital point. The Fire Scale Beast let out a deafening roar, then slowly collapsed, turning into a ball of flame and disappearing.

"Is everyone alright?" Ye Yuanchen asked, panting heavily. The battle had just exhausted a lot of his spiritual energy.

Mu Wanyue and Lu Zixuan shook their heads, indicating that they were fine. After resting for a while and recovering some of their spiritual energy, they continued their journey deeper into the immortal island.

The deeper they ventured into the immortal island, the stronger the fluctuations in spiritual energy became, and the more complex the surrounding restrictions grew. They encountered barriers composed of spiritual energy, and Ye Yuanchen, relying on his profound understanding of spiritual energy and keen insight, successfully broke through these barriers time and time again.

In a secluded valley, they finally discovered the traces of the Spirit Source Sacred Fruit. The Spirit Source Sacred Fruit grew on a huge spirit tree, which was covered with fruits that emitted multicolored light, and each fruit exuded a powerful spiritual energy.

"We've finally found it!" Mu Wanyue said excitedly, but she quickly calmed down. "However, there must be some protective barriers around here."

Ye Yuanchen carefully observed the environment around the spirit tree and discovered some runes hidden among the flowers and plants. These runes were interconnected, forming a powerful defensive array. He began to study how to break the array, and after much thought, he finally found the array's core.

Just as he was about to break the array's core, a group of spirit snakes suddenly emerged from the ground. These spirit snakes emitted a ghostly light and flicked their venomous tongues.

"Another troublesome fellow!" Lu Zixuan said helplessly. He quickly set up a killing formation and began fighting the spirit snake.

Mu Wanyue assisted Ye Yuanchen in breaking the formation. She used her spiritual power to interfere with the operation of the runes, creating an opportunity for Ye Yuanchen. Ye Yuanchen concentrated his energy and injected a powerful stream of spiritual power into the formation's core, successfully breaking the defensive formation.

After the formation was broken, Ye Yuanchen slowly walked towards the spirit tree. He reached out, wanting to pluck the Spirit Source Sacred Fruit. Just as his hand was about to touch the sacred fruit, a creature resembling an elf suddenly jumped down from the tree.

"You greedy humans, how dare you try to seize the sacred fruit of the Spirit Source!" the elf said angrily, holding a small magic wand in its hand, the wand shimmering with light.

Ye Yuanchen quickly explained, "We are not greedy people. I need the Spirit Source Sacred Fruit to break through my bottleneck and save more people."

The elf scoffed dismissively. "Do you think I'd believe you? This Spirit Source Sacred Fruit is a sacred object of the Immortal Island; it must not fall into your hands."

With that, the elf waved her wand and cast a spell at Ye Yuanchen. Ye Yuanchen quickly dodged, knowing that a battle with the elf was inevitable.

He unleashed his magical healing techniques, transforming spiritual energy into threads that coiled around the elf. The elf nimbly danced in the air, dodging Ye Yuanchen's attacks. Mu Wanyue and Lu Zixuan also joined the battle, and the three of them engaged in a fierce contest of magic and divine arts against the elf.

During the battle, Ye Yuanchen discovered that the elves' magic was primarily based on the power of nature. He had a sudden inspiration and changed his attack strategy. He unleashed a magical technique that could merge with the power of nature, combining his own spiritual energy with the surrounding natural energy to form a powerful force.

This power made the elf feel threatened, and it began to take the battle seriously. It cast a powerful magical shield around itself while simultaneously increasing the intensity of its attacks.

Seeing this, Mu Wanyue used a supportive magic technique to weaken the elf's magical shield. Lu Zixuan then set up a large trapping array, confining the elf within. Taking advantage of the opportunity, Ye Yuanchen launched his final attack, gathering all his spiritual power into his hand and slamming it towards the elf's magical shield.

With a deafening roar, the elf's magical shield shattered, and it was severely injured. Ye Yuanchen walked up to the elf and said, "We truly meant no harm. I simply wish to use the power of the Spirit Source Sacred Fruit to better protect the world."

The elf looked into Ye Yuanchen's sincere eyes and its heart stirred slightly. After thinking for a moment, it said, "If you can promise me that you will use the power of this Spirit Source Sacred Fruit to help the Immortal Island restore some of its vitality, I will give it to you."

Ye Yuanchen agreed to the elf's request without hesitation. The elf nodded, waved its wand, plucked the Spirit Source Fruit from the tree, and handed it to Ye Yuanchen.

Ye Yuanchen accepted the Spirit Source Sacred Fruit, his heart filled with gratitude. After consuming the fruit, he immediately began secluded cultivation, hoping to break through his bottleneck with the fruit's power. Mu Wanyue and Lu Zixuan protected him from harmonizing, ensuring his safety during his cultivation.

After a period of secluded cultivation, Ye Yuanchen successfully broke through the bottleneck, his cultivation level improved significantly, and his understanding of the integration of cultivation and medicine reached a new height.

He stepped out of his secluded retreat, looked at Mu Wanyue and Lu Zixuan, and said, "Thank you for your companionship and help. Now that I have broken through the bottleneck, we can better fulfill our mission."

Mu Wanyue and Lu Zixuan smiled with satisfaction. They left the South China Sea Immortal Island, carrying a bountiful harvest, and headed back towards the town where the Ye family lived. On their way back, they encountered some fishermen stranded by a shipwreck, and Ye Yuanchen easily rescued them using his newly improved immortal medical skills.

Upon returning to town, Ye Yuanchen shared his experiences on the South China Sea Immortal Island with the disciples of the Ye family, allowing them to learn much about cultivation and how to deal with danger. He continued to treat patients at his clinic, using his even more powerful immortal medical techniques to bring hope to more patients.

However, unbeknownst to them, the peace of the Immortal Island was shattered after they left. Some evil cultivators learned of the harvesting of the Spiritual Source Fruit and launched a frenzied plunder of the island, attempting to find more treasures. Ye Yuanchen and his companions were about to face a new challenge; they must once again step forward to protect the peace and tranquility of the world.
