Amid the explosions, Wu Tianliang turned his gaze toward Fang Yan and saw a translucent, emerald-green sword suddenly appear in Fang Yan's hand.
"Ha! That sword of yours is as fragile as your life!"
Wu Tianliang was so confident because these Shield-Transforming Bugs were creatures he had spent years raising. Shield-Transforming Bugs were already rare, and gathering so many of them was an even greater rarity. They were tiny Gu Worms whose shells were harder than solid rock. When clustered together, they could protect the Gu practitioner. Ordinary martial artists, and even hard-chi masters at the Great Grandmaster level, would find them difficult to breach. For this reason, they had earned a flattering nickname: "Turtle-Shell Bugs."
