I know I asked before but isn't the old mister ouyang some God or something? only to enter the inner temple, there already died hundreds of top notch epic experts. to figure out what the 2 mythical guardians are, some more. And he sits there soon for 1 year. where did he get the food and other stuff to keep living until now? Yeah I want him to return alive to, but I also want this questions figured out. How did he survive, wagt no other can do?
