Ghost Needle Crosses Customs

I have been practicing medicine in the countryside for ten years, and I have adhered to an ancestral precept: not to give acupuncture at night, not to feel the pulse when I am sick, and not to treat strange diseases. But since I took over the box of old silver needles left by my grandfather, the entire mountain village's old taboos and dusty secrets came to life overnight. The deceased patient who knocks on the door in the middle of the night, the village rules that reverse red and white matters, the lingering old curses, the life-threatening taboos hidden in local customs... Everyone in the world is afraid of the strange things in the mountains and wilderness, but I am the only one who holds ghost needles in my hand, using orthodox medical principles to break through conventional methods, and using ancestral secret needles to suppress weird things in the world. The needle falls to separate yin and yang, and the thread breaks cause and effect. All the obsessions, evil obstacles, worldly ghosts and treacherous things in the world can be overcome with one shot, and can be alleviated with one shot.
