Years ago, the grandfather saved a nine-tailed fox undergoing its heavenly tribulation in the mountains. To repay him, the fox spirit promised to bless his family with the long-awaited gift of a child.
But when the baby was born, he turned out to have an intellectual disability from birth. The family was both overjoyed and worried. When the boy was eight, a reclusive wandering doctor came to their home and offered to take him up the mountain to train.
Over the next twenty years, his master taught him peerless medical skills, but imposed one ironclad rule: he must never grow intimate with a woman. If he broke this vow, his medical skills would be lost and disaster would follow.
At twenty, the young fool had mastered his studies and bid farewell to his master before entering the bustling city.
People mock him as simple-minded and awkward, but a single flick of his silver needle can bring the dead back to life. The wealthy and powerful rush to curry favor with him, while beautiful women of all kinds keep drawing close.
Bound by his master's prohibition, he must choose between the tender temptations of worldly life and the path of healing others. Watch as this supposedly foolish young man stirs up the entire city with a single set of miraculous needles.
