What are your thoughts on Rudeus being called a 'self-serving fraudster' by the world, Mr. Allen?"

"First of all, please don't fabricate my title; I have the right to hold those responsible accountable. As for Rudy: I ​​have repeatedly emphasized that in my eyes, he is like my child. He does have some insecurities and timidity, but these only prove that he is a real person. This era's trajectory has accompanied his growth, and to be responsible, he should be considered a legend."
