The Immortal Physician's Transmigration: Miraculous Rejuvenation

Carrying the clues obtained from the stone tablet in the Black Abyss Cave, Ye Yuanchen and his companions officially embarked on their journey to find the three mysterious keys. According to the inscription on the stone tablet, the three keys are hidden in secret places in the mortal realm, the spirit realm, and the cultivation realm, and the search for each key is destined to be full of twists and turns.

The group first focused their attention on the mortal realm. Following the clues, the key to the mortal realm might be hidden in an ancient, abandoned city. This city was once prosperous, but was abandoned after a sudden disaster and is now overgrown with weeds and eroded by time.

Ye Yuanchen led the special operations team cautiously into the abandoned city. A decaying stench permeated the air, and amidst the ruins, glimpses of its former glory could still be seen. The team members spread out, carefully searching every corner.

Suddenly, a team member discovered a strange stone slab in front of a collapsed temple. The slab was covered with obscure and incomprehensible runes, which shimmered with a faint light. Ye Yuanchen and Lu Zixuan immediately rushed over and carefully studied the runes.

While observing the runes, Lu Zixuan compared them with the ancient book he carried with him and said, "Young Master Ye, these runes seem to be pointing in a certain direction."

After some analysis, they discovered that the rune pointed in the direction of an ancient well in the center of the city. The group arrived at the well and found it to be bottomless, filled with a mysterious aura.

Ye Yuanchen used his spiritual power to illuminate the interior of the ancient well. The well walls were covered with various strange patterns, which began to shimmer and glow as spiritual power was poured in.

"There's definitely something strange in this well, everyone be careful." Ye Yuanchen said, and jumped into the ancient well first. The other team members followed suit.

When they reached the bottom of the well, they discovered a hidden chamber. Inside the chamber lay a massive stone coffin, also covered in runes. Around the coffin were several enormous stone beast statues, seemingly guarding it.

Just as the group approached the stone coffin, the stone beast statues suddenly came to life. They opened their blood-red maws and pounced on the group. The stone beasts emanated a powerful aura, and each attack was accompanied by a sharp whistling sound.

"Everyone be careful, these stone beasts are incredibly powerful." Ye Yuanchen drew his Spirit Void Holy Sword and unleashed the "Spirit Realm Chaos Suppressing God Technique," golden sword energy crisscrossing as he slashed at the stone beasts.

Mu Wanyue wielded the Spirit Whip, its pink and rainbow-colored shadows swirling like a dragon emerging from the sea, lashing against the stone beast. Bai Youruo played the Spirit Flute, its notes transforming into golden sound waves that disrupted the stone beast's movements. The other team members also unleashed their spells, engaging the stone beast in a fierce battle.

During the battle, Ye Yuanchen discovered that the stone beasts' eyes were their weak point. He seized the opportunity and thrust a sword aura towards the eye of one of the stone beasts. The stone beast let out a painful roar and swayed.

"Attack their eyes!" Ye Yuanchen shouted.

The team members immediately adjusted their attack direction, concentrating their efforts on the stone beasts' eyes. Under the combined attack of everyone, the stone beasts fell one after another, turning into rubble.

After dealing with the stone beast, Ye Yuanchen and the others arrived at the stone coffin. Ye Yuanchen circulated his spiritual power, attempting to open the coffin. However, the runes on the coffin released a powerful resistance, preventing it from being opened.

After carefully studying the runes, Lu Zixuan said, "Young Master Ye, these runes require specific spiritual energy fluctuations to decipher. Perhaps we need to find a way to release spiritual energy that matches the frequency of the runes."

Ye Yuanchen pondered for a moment, trying to activate the runes with different spiritual energy fluctuations. After several attempts, he finally found the correct frequency. The stone coffin slowly opened, and a soft light emanated from it.

Inside the stone coffin lay an ancient key, its surface engraved with mysterious patterns and emanating a faint spiritual energy.

"This should be the key to the mortal realm." Ye Yuanchen picked up the key, a surge of joy in his heart.

However, just as they were about to leave the ancient well, they suddenly heard a commotion coming from the ground. Ye Yuanchen used his spiritual power to investigate and discovered that a group of remnants of a dark force were heading towards the abandoned city.

"It seems the dark forces have also set their sights on this key. We can't let them succeed; we must leave as soon as possible," Ye Yuanchen said.

The group quickly climbed up the ancient well. Just as they emerged, they encountered the remnants of the dark forces. These remnants were numerous, armed, and their eyes gleamed with ferocity.

"Hand over the key!" the leader of the dark forces shouted.

Ye Yuanchen sneered: "You scum of darkness, you won't get the key."

A fierce battle erupted instantly. Ye Yuanchen and his companions engaged in a desperate struggle against the remnants of the dark forces. Ye Yuanchen's golden sword energy, Mu Wanyue's spirit whip, Bai Youruo's flute music, and the team members' spells clashed violently with the dark power of the dark forces.

During the battle, Ye Yuanchen discovered that the remnants of the dark forces seemed to be stalling for time, and their true purpose might be to attract more dark forces.

"We can't stay here any longer. We'll fight and retreat," Ye Yuanchen shouted.

The group fought and retreated, heading towards the edge of the abandoned city. The remnants of the dark forces pursued relentlessly, and a thrilling chase ensued within the city.

Just as Ye Yuanchen and the others were about to retreat to the outside of the city, a black barrier suddenly appeared in front of them, blocking their way.

"Oh no! This is a dark barrier! We're trapped!" Lu Zixuan shouted.

Seeing this, the leader of the dark forces laughed triumphantly: "You have no way to escape. Hand over the key obediently, and perhaps we can spare your lives."

Ye Yuanchen and his companions are in dire straits. Can they break through the dark barrier, escape the pursuit of the dark forces, and continue their search for other keys with the key to the mortal realm? How will Ye Yuanchen and his group cope with this sudden crisis? Everything is uncertain, but their belief in protecting the Three Realms burns like an inextinguishable flame.
