I stood in the middle of the room, waiting patiently for the presence of the martial arts master. Fortunately, this martial artist didn't let me wait too long. Otherwise, I would turn my head and leave. On the wall in front of me, a man appeared slowly in the void, dressed as a magician, with a smile on his face. The martial artist looked at me lightly and said, "In order not to delay time, I have to tell you briefly about the rules here. In this room, you can make all your solutions, as long as you can hit me, even if you win."

I think it's not easy....
