Ultraman: Teaching Zeta to Box and Accidentally Hitting the Golden One

[Ultraman fanfic + canon changes to fit the plot + comedy] Su Chen was chosen as a human host and sent to the Land of Light to join its trainee program. He obtained the Divine Skill Comprehension System. At his first beam-firing exam, Zeta fired a stylish beam and revealed that Su Chen was his master!

Just don't blow us up with the Buddha's Wrath Fire Lotus!” “What do you mean, Heaven-Turning Seal? Swords, come forth? Those are all too dangerous! Ban them!” “What is this new generation of the Land of Light flying on swords? One sword, and frost chills the fourteen provinces?” One day, at the Land of Light's year-end meeting, Ultraman King was stunned. The strongest mentor and human host was actually Su Chen!?
