Me at Thirty: Switching to Magician at the Start

Martial arts world: The heroes who thought they had found Su Chen's weakness, when they surrounded him at close range, suddenly saw him take out a 'staff', with the Dugu Nine Swords in one hand and the Eighteen Dragon-Subduing Palms in one hand! Wizarding World: "Sorry, I'm a melee mage!" Shape Moon World: "Lancer! Come and test your spear skills with me!" "The Other Side of Redemption: Holy Spear of Punishment!"
