To be fair, Little Poison Insect was not a very hardworking Martial Artist.
He belonged to that group of incredibly lucky individuals. Many years ago, when he was still a poor man, he chanced upon a corpse in a ditch. According to the Jianghu experience he acquired later, that corpse must have belonged to a Hero. The Hero had died there for unknown reasons, his Prosthetic Body disassembled extensively, leaving only a few biological parts and a decorative textile.
Little Poison Insect picked up that textile, which was embroidered into a Magnetic Chain. It was from this Magnetic Chain that Little Poison Insect downloaded resources related to martial arts, which even included Inner Strength, External Strength, and Military Martial Arts.
And so, he quietly cultivated his martial arts.
