Once a physician and martial artist who practices both skills masters the "Emperor's Ten Needles," even with the most common silver needles, they can treat many difficult and complicated illnesses.
Fang Bai originally obtained the Five Elements Acupuncture Set from an antique market, which was crafted from Green Wood Marrow and four other rare materials even in the Immortal Realm. With these five needles in hand, Fang Bai's use of the "Emperor's Ten Needles" when saving people would have a significant supportive effect.
Now, Fang Bai had great confidence, and no matter what kind of diseases or injuries he encountered, as long as the person still breathed, he could save them.
As his cultivation level continued to rise in the future, Fang Bai would be able to perform all ten techniques of the "Emperor's Ten Needles."
By then, although Fang Bai would still not be able to bring the dead back to life, he could definitely heal flesh and mend bones.
