It was the classic line of Shizuhito Juushirou from Silver Soul.

Hijikata Juushirou was one of the main characters in Gintama. His classic quote was as follows: You want to be my friend at this level? The two of them relied on each other to grow. You are no exception. There was nothing that a barbecue couldn't solve. If there was, then two. In this world, there is only one person who will not die, and that is me. There was nothing in this world that money could not buy. If there was, then there would be more money. Six, my legs. My life goal is to become the strongest samurai in Japan, and I will do whatever it takes. To defeat me, you must be stronger than me. There was nothing in this world that time could not heal. If there was, then there would be more time. If I ask you to do something, you must do it. Because I will not allow anyone to disobey my orders.
