The Immortal Physician's Transmigration: Miraculous Rejuvenation

Ye Yuanchen and his companions crossed the Gate of the Spirit Realm and returned to the world of cultivation and the mortal realm. Their return attracted widespread attention from all walks of life. Representatives from various sects in the cultivation world came to welcome them, and the royal families of the mortal world prepared grand celebrations to commend their achievements in saving the spirit realm and protecting world peace.

However, Ye Yuanchen knew that the information they had gained from their trip to the Spirit Realm was too significant to simply wallow in the joy of victory. He decided to summon important figures from both the cultivation world and the mortal world to inform them of the secrets of the Spirit Realm and the potential crises they might face in the future, so that everyone could prepare together.

In a grand gathering, Ye Yuanchen stood on a high platform, his expression solemn as he began to recount their experiences in the Spirit Realm. Below him gathered the leaders and elders of the cultivation world, the kings and ministers of the mortal world, and many other learned individuals. They listened quietly, their expressions shifting with each word Ye Yuanchen spoke, sometimes showing shock, sometimes worry.

"In the Spirit Realm, we discovered the existence of a dark force even more powerful than the Dark Night Demon Lord. This dark force originates from an ancient source of darkness, hidden deep within the Spirit Realm, constantly eroding its foundations. We went through countless hardships to find and destroy the source of darkness, but this does not mean the crisis is completely over." Ye Yuanchen's voice echoed across the plaza, ensuring everyone could hear it clearly.

Mu Wanyue continued, "The existence of this dark force is not only a threat to the spirit world, but also a threat to the entire world. It may resurface, or other similar dark forces may quietly emerge elsewhere. We must strengthen our cooperation and enhance our own strength in order to better cope with future challenges."

Lu Zixuan stepped forward and displayed the soul array model he had created in the Spirit Realm. "This is a soul array I researched in the Spirit Realm. It combines the power of the soul with the essence of array formations. Through this array, we can better utilize the power of the soul in battle, attacking and defending against the enemy's soul. I hope to pass this array on to all cultivators so that we can all learn and improve upon it together."

Bai Youruo also began to play the Spirit Sound Flute, performing a piece of Spirit Sound Immortal Technique music that she had comprehended in the Spirit Realm. "My Spirit Sound Immortal Technique has also made new breakthroughs in the Spirit Realm. This technique can manipulate soul power through flute music, not only healing soul wounds but also interfering with and attacking the enemy's soul in battle. I am willing to share my cultivation experience of the Spirit Sound Immortal Technique with everyone so that we will have more means when facing the forces of darkness."

The audience below listened to their explanations and demonstrations, and began to discuss among themselves. Some cultivators showed great interest in soul formations and spiritual sound techniques, realizing that these new cultivation methods and combat skills might bring them new breakthroughs and advancements. Representatives from the mortal world, on the other hand, began to consider how to support the cultivation world materially and in terms of manpower to jointly combat the threat of the dark forces.

In the days that followed, Ye Yuanchen and the others became busy. They opened lectures and training courses in both the cultivation world and the mortal world, imparting the knowledge and skills they had acquired in the spirit world. Ye Yuanchen personally taught cultivators how to better integrate cultivation with medicine. Using his own practical experience in the spirit world as an example, he explained how to use immortal medical techniques to treat both spiritual and physical injuries, and how to use the power of nature and light to counteract the power of darkness in battle.

Mu Wanyue focuses on cultivating female cultivators, encouraging more women to bravely embark on the path of cultivation. She shares her experiences in the cultivation process, teaching her female disciples how to establish themselves in the male-dominated cultivation world, and how to leverage their unique strengths, such as keen perception and strong affinity, to achieve better results in combat and cultivation.

Lu Zixuan traveled between various sects, helping them set up soul formations. He tailored suitable formation layouts to the terrain and spiritual energy characteristics of different sects. During the setup process, he also explained the principles and operation methods of the formations to the sect disciples in detail, enabling them to master and utilize soul formations and enhance their sects' defensive and offensive capabilities.

Bai Youruo's Spiritual Sound Immortal Technique Training Class attracted many cultivators and some mortals with musical talent. She started by teaching the basics of flute playing, gradually guiding students to master how to use flute music to mobilize their soul power. She also organized ensemble practice sessions for the students, creating even more powerful soul power fluctuations through the combined flute playing of multiple people to cope with large-scale invasions of dark forces.

However, the process of imparting knowledge and skills was not without its challenges. Some cultivators resisted the new cultivation methods and philosophies, believing that traditional cultivation methods were already powerful enough and unwilling to accept these external changes. Meanwhile, some forces in the mortal world worried that excessive support for the cultivation world would affect their own interests and status, and thus hesitated to provide resources and manpower.

Ye Yuanchen and his team knew that changing people's perceptions and attitudes required time and patience. They continuously communicated with various parties, using real-world examples and results to persuade those who were skeptical. They also organized practical exercises and demonstrations, allowing everyone to witness firsthand the powerful effectiveness of soul formations and spiritual sound magic in simulated battles against dark forces.

In a valley within the cultivation world, a grand practical exercise was underway. Ye Yuanchen led a group of cultivators, employing soul arrays and spiritual sound techniques to combat the dark forces simulated by Lu Zixuan. The light emitted from the soul arrays illuminated the entire valley, while the flute melodies of the spiritual sound techniques echoed through it, stirring the hearts of all present. In the battle, the cultivators successfully withstood the attacks of the dark forces and gradually repelled them. This exercise demonstrated the feasibility and effectiveness of the new method to many initially skeptical cultivators and mortal forces, and their attitudes began to gradually change.

As time went on, more and more people began to accept and learn the new knowledge and skills brought by Ye Yuanchen and others. Cooperation between the cultivation world and the mortal world also became closer. Royal families of various countries increased their resource investment in cultivation sects, providing more spiritual mines, immortal herbs, and other cultivation resources, as well as substantial manpower and resources for building fortifications and training cultivation talents. In return, cultivation sects dispatched disciples to the mortal world to help them resolve supernatural events and natural disasters, protecting the safety of mortals.

Throughout this process, Ye Yuanchen and the others did not cease their cultivation and exploration. They knew that although the world was currently at peace, the forces of darkness could strike again at any moment. They continued to delve deeper into the integration of cultivation with medicine, soul power, and spiritual sound techniques, hoping to further enhance their strength and be better prepared to face future crises.

Meanwhile, they also began to focus on other corners of the world, dispatching disciples and envoys to search for traces of other dark forces. They discovered some signs of possible corruption by dark forces in remote areas; although these signs were still faint, they were enough to raise their alarm. Ye Yuanchen and the others decided that, while strengthening their own power and the world's defenses, they would take the initiative to eliminate the dark forces before they grew stronger, ensuring the long-term continuation of world peace and tranquility.
