The Immortal Physician's Transmigration: Miraculous Rejuvenation

As the deep roar echoed through the ruins, Ye Yuanchen and the others watched the direction from which the sound came with vigilance, circulating their spiritual energy and preparing to deal with any potential dangers.

"Everyone, stay alert and don't act rashly. This roar contains immense power; clearly, the being inside is not to be trifled with," Ye Yuanchen said in a low voice, his eyes revealing solemnity and caution.

Mu Wanyue nodded slightly, the Spirit Whip in her hand trembling slightly, its pink light flickering in the darkness, as if echoing the tense atmosphere around her. "I feel that this power is closely connected to this ruin. Perhaps the guardian spirit here has been angered by our intrusion."

Lu Zixuan quickly set up a simple defensive formation around them. Although the formation's effectiveness might be limited in this mysterious ruin, it was better than nothing. He took out array flags and spirit crystals from his storage magic treasure, inserted them into the ground in specific positions, and chanted incantations. The runes on the array flags gradually lit up, forming a faint spiritual energy shield that enveloped everyone. "Let's set up the defense first and see how things go."

Bai Youruo began to play the Spiritual Sound Flute, the notes transforming into a gentle sound wave that spread throughout the ruins. She attempted to use the flute's sound to perceive the surrounding environment and hidden dangers, while also hoping that the soothing effect of the sound waves could calm any potential guardian spirits.

However, their caution did not prevent danger from approaching. A colossal figure slowly emerged from the depths of the ruins, and as it drew nearer, the ground began to tremble slightly. It was a guardian spirit resembling a giant, its entire body composed of ancient stones, covered with mysterious runes that emitted a faint glow. Its eyes, like burning green flames, stared intently at Ye Yuanchen and the others, filled with anger and vigilance.

"Outsider, why have you trespassed into this forbidden land?" The guardian spirit spoke in a deep and majestic voice, which echoed through the ruins, making everyone's ears ring.

Ye Yuanchen stepped forward, cupped his hands, and said, "We have no ill intentions. We simply sensed a mysterious power emanating from these ruins and were worried that it might pose a threat to the Three Realms, so we came to explore. Our purpose is to protect the peace of the Three Realms. Please forgive us if we have offended you."

The guardian spirit snorted coldly, "Hmph! You insignificant creatures always presumptuously trespass into places you shouldn't be. The power here is beyond your control. Leave at once, or don't blame me for being impolite!"

Mu Wanyue frowned and said, "We can't just leave like this. Now that we're here, we must find out the secrets of this place. If there is any danger, we will find a way to solve it instead of running away."

Enraged by Mu Wanyue's words, the guardian spirit suddenly raised its massive arm, the runes on it shining brightly, and then slammed it down on the crowd.

Seeing this, Ye Yuanchen immediately unleashed the fusion technique of "Spirit Realm Chaos Suppressing God Technique" and the Spirit Void Holy Sword, leaping high into the air and unleashing a golden spiritual energy blade at the guardian spirit's arm. The blade collided with the guardian spirit's arm, producing a loud bang. The powerful impact forced Ye Yuanchen back several steps, but he successfully blocked the guardian spirit's attack.

Mu Wanyue wielded the Spirit Whip, unleashing the immortal technique "Spirit Dance Illusion Whip Void Break." The whip transformed into a pink light, wrapping around the guardian spirit in an attempt to restrict its movements. The whip struck the guardian spirit, failing to inflict any real damage, but it did slow its movements somewhat.

Within the defensive formation, Lu Zixuan manipulated its spiritual power, launching beams of spiritual energy towards the guardian spirit's eyes and other vital areas. However, the runes on the guardian spirit flickered, deflecting all the beams.

Bai Youruo played the Spirit Void Flute, the notes transforming into sonic blades that sliced ​​through the runic light on the guardian spirit's body, attempting to weaken its defenses. However, the guardian spirit's power was immense, and the flute's attack was not very effective.

Under the onslaught of the group, the guardian spirit grew even more enraged. It opened its mouth and spewed out a beam of black energy, containing powerful dark forces and corrosive substances, which swept towards Ye Yuanchen and the others.

Ye Yuanchen and the others had no time to dodge and could only brace themselves for the attack. They gathered all their power together to form a powerful spiritual energy shield, attempting to withstand the impact of the black energy beam.

The energy beam collided with the spiritual energy shield, producing a deafening explosion. Everyone felt a tremendous impact, as if struck by a heavy hammer, and were sent flying backward. The spiritual energy shield shattered instantly under the attack, and everyone suffered varying degrees of internal injuries, blood trickling from the corners of their mouths.

"This guardian spirit is too powerful. We need to think of a way." Ye Yuanchen struggled to get up, wiped the blood from the corner of his mouth, and his eyes revealed a hint of anxiety.

Despite his pain, Lu Zixuan began to carefully examine the runes on the guardian spirit. He discovered that although these runes were powerful, they seemed to contain some kind of pattern and weakness. "Everyone, pay attention. I've discovered some patterns in the runes on it. If we attack specific nodes of these runes, we might be able to weaken its power."

Upon hearing this, everyone immediately adjusted their tactics. Ye Yuanchen unleashed the "Spirit Realm Holy Healer's Demon-Slaying Divine Technique," transforming spiritual power into precise beams of light that shot towards the rune nodes indicated by Lu Zixuan. Mu Wanyue wielded the Spirit Void Whip, its tip splitting into countless tiny branches, also lashing towards the rune nodes. Bai Youruo played the Spirit Void Melody Flute, the flute's sound transforming into a powerful soul-shaking force, interfering with the guardian spirit's control over the runes.

Under the combined attack of everyone, the runes on the guardian spirit began to flicker erratically, and its power seemed to have weakened.

"It works! Let's continue the attack!" Ye Yuanchen shouted excitedly.

However, the guardian spirit was not so easily defeated. Sensing its power weakening, it suddenly changed its attack method. It plunged its hands into the ground and then pulled them out violently, causing countless huge stone spikes to appear on the ground and shoot towards Ye Yuanchen and the others.

Ye Yuanchen and the others quickly dodged, but there were too many stone spikes, and they were still somewhat overwhelmed. While dodging the stone spikes, Mu Wanyue was accidentally cut on the arm by one, and blood flowed freely.

"Wanyue, are you alright?" Ye Yuanchen asked with concern.

"I'm fine, just a minor injury. Let's keep fighting!" Mu Wanyue said through gritted teeth.

Just as everyone was in trouble, Ye Yuanchen suddenly had a flash of inspiration. He remembered a magical artifact he had obtained while exploring ancient ruins in the cultivation world—the "Spirit Illusion Mirror." This artifact could reflect enemy attacks and return them to the enemy with their power amplified several times over.

"I have an idea!" Ye Yuanchen said, taking out the Spirit Illusion Mirror from his storage magic treasure. He aimed the mirror at the guardian spirit, then used his immortal magic to guide the stone spikes launched by the guardian spirit toward the mirror.

The stone spikes struck the mirror and were reflected back, their power amplified several times over. The guardian spirit, unable to dodge in time, was struck by the stone spikes it had launched, sustaining several deep wounds from which black liquid oozed.

"Great opportunity! Let's intensify our attack now!" Ye Yuanchen shouted.

Taking advantage of the guardian spirit's injury, the group launched another fierce attack. With everyone's combined efforts, the guardian spirit finally succumbed, its body gradually collapsing into countless stones and runes that dissipated into the air.

As the guardian spirit dissipated, the mysterious power within the ruins seemed to calm down somewhat. Ye Yuanchen and the others breathed a sigh of relief, but they knew this was only a temporary victory. They had to continue exploring the ruins more deeply to uncover its secrets and truly resolve any potential crises.
