It's been a while since pang bo was last seen, and now he's back. He's worried that his brother is trying to get in on the action, but he doesn't want to reveal his true feelings yet. He wants to test the strength of his brother's muscles, and he wants to see if they can hold their own against some of the best fighters in the world. He decides to go along with his brother to test their strength. Ooh, sounds like a good idea.
