Yang Zheng was so sad and angry that he traveled through time and became a local dog in a fantasy world. He was a newbie in the binding and copying system and was extremely unskilled in the business. I just want to copy the peerless technique, but I grab a dog hair; I want to copy the magic elixir, but I find out the system's "Beginner's Guide" for my own use. Yang Zheng flipped up the table angrily: "I want to complain!" The system felt aggrieved: "It's my first time working on a system, can I give it a five-star review?"
