As a professional dragon slayer, Zhang Dali kills enough dragons to circle the earth three times every day.
Until he received a letter of complaint: "Dear Sir, the Charizard you killed yesterday is an endangered species. Please stop illegal dragon killing immediately."
The next day he was sued by the animal protection organization: "Please respect the rights of dragons, the video of them crying has exceeded 100 million views!"
When I was confused, a young dragon knocked on the door timidly: "Um... Do you need a legal dragon slaying license certified by the Dragon Protection Association?"
