Vince has a smug look on his face when he saw Fred acting like that, he replied at his question nonchalantly,
"Eh? Isn't it obvious? That's my new hideout."
Not paying any mind to Fred, Vince proceeds forward, entering inside the tree.
After a while Fred recovered from his shock and also followed.
Inside, he saw stairs that lead underground. Vince already went ahead walking under the tree/ground.
Fred followed without saying anything more. At the bottom of the stairs, a wide and spacious hall is what greeted him.
There, training equipment is placed on one part. At the center of the hall is a platform made out of wood and acts as a ring for people to spar. There are also a few benches around it that people can sit on to watch as people practice their techniques.
