Master of Kung Fu Vol 1 (1974) #21 Fn
Part 1: Season of Vengeance ... Demmy Marston, an underworld figure in Miami, blames Shang-Chi for his girlfriend's death and puts out a general hit order. Shang-Chi, having swum ashore, finds Marineland. He enters, curious about the oxymoron in its name. He encounters a leaping, cheerful-looking dolphin. When he hears a gunman behind him, he ducks, just as the dolphin leaps into the path of the bullet. Shang-Chi takes down the gunman, as well as five others. Another team appears, too far away to fight, so he dives into another tank.Part 2: Moment of Death! This tank holds a shark! Shang-Chi punches it a few times and knocks it out, then has to surface for air. A gunman punches him and knocks him out. He wakes on an island in the Florida Keys, tied to a tree, at the mercy of Marston. Marston beats Shang-Chi with a tree limb. Only gradually does he realize that a team of Si-Fan assassins has come ashore and surrounded his own team of assassins. A helicopter lands, and Fu Manchu emerges. He wants to savor Shang-Chi's death in his own way and on his own schedule. He holds out a viper that bites Marston neck and kills him. Shang-Chi, freed from his bonds, collapses on the sand.
