Red Mansion: from a Loving Father and a Filial Son to Not Eating Beef

He traveled through time and became Jia Rong, a direct descendant of Ning Guofu in the Red Mansion. He also awakened the sign-in system, but what the hell is he only able to sign in three times? Jia Rong: System, how can I live without you? What? Dragon Ball Earth's first appearance of Vegeta's combat power (gradually unlocked)? Divine medical skills? A can of fairy beans? Jia Rong: Jie Jie Jie, I don't eat beef, I want to protect my Red Mansion.
