Spiritual Qi Revival: From the Start, I Transform into a Giant of Light

After transmigrating to a world of supernatural powers, I got the Ultraman System from the start. While humanity's front lines were still struggling to hold off the invasion of strange beasts, I blasted straight into the beast tide with a Zeperion Ray. What? You say you're the Beast God? I'm the first light in the universe, for crying out loud! Who are you trying to go toe-to-toe with? You say you've plunged the world into darkness? Bring it on! I can transform into a dark giant too.
