Unconsciousness, often enough, is the body's final form of self-protection.
After a long, long time, Feng Yin finally eradicated all the worms inside this person's body, reconnected his meridians, and cleared all the toxins.
However, his body had lost a lot of flesh and blood, and even though the Spiritual Transformation Technique's supernatural healing power could regenerate flesh and bone, it would not be possible to fully recover instantly. But this man was a Human-Level cultivator, with a physique far superior to an ordinary person, once the restrictions on his Dantian were lifted and his meridians could heal on their own, he would be completely healed in at most a few months.
With a touch of the spiritual power from the Spiritual Transformation Technique, the man regained consciousness. When he opened his eyes and saw Feng Yin, he smiled faintly and said, "I knew I would not die; Heaven truly favors the good."
