These Mother-child Needles, a total of twelve, could be said to be his life-saving trump cards.
The internal structure of the Mother-child Needles is intricately complex, observable under a microscope like an electronic chip, with an internal structure as complicated and labyrinthine as a maze.

Let alone a perfect copy, he couldn't even produce a low-quality imitation.
These twelve Mother-child Needles had been bought by Cheng Suo for ten million US dollars at an auction abroad four years ago, which afterward proved his vision to be astute.
