1. Core highlights: Demonstrating miraculous medical skills, short and fast slap-in-the-face rhythm, paving the way for the initial prototype of power.
2. Soul jump: The protagonist must change his body every 20 days, otherwise the host soul will be shattered due to being unable to withstand the pressure of the fairy soul.
3. Miraculous medical instinct: During the period of possession, the fairy soul automatically tempers the host's body (washes the essence and cuts the marrow), all diseases are eliminated, and the physical fitness increases dramatically.
4. Parting gift: Before leaving, the protagonist will leave a most suitable "cultivation technique" deep in the host's mind based on the host's physique as rent.
Protagonist identity:
Ye Wudao: The "Nine Heavens Medical Saint" in the immortal world was plotted by the five immortal emperors together for refining the heaven-defying divine elixir. His body fell and his remaining soul fled to the lower realm.
Main goal:
Use the host's body to collect resources, repair the remaining soul, and finally rebuild the immortal body and fight back to the immortal world.
These "host disciples" who were unintentionally accepted eventually established the "Wudao Immortal Sect" in the mortal world that terrified the upper world.
