I remembered the Copper Coin Sword lying on the ground. Perhaps it could be used to sever the puppet's head, which might prevent Qu Guo from being injured in the chest again. After the puppet was destroyed, I could then figure out how to deal with the skin sack attached to his chest.
I tripped Qu Guo's legs at an angle, bringing him to the ground, then I pressed one hand down on his arm and used my knee to pin him by his stomach, keeping him from getting up, and I grabbed the Copper Coin Sword that had dropped to the ground.
Because the sword had been smeared with my blood and had fallen to the ground, dust had clung to its surface forming clumps of dirt. I wasn't sure if this would affect its sharpness, so I had no choice but to wipe it against my body to clean it.
