Lin Feng, an ordinary college student, witnessed Gomora, the monster in the tokusatsu drama, coming to the real world on an ordinary afternoon, and the city instantly turned into a sea of fire. In despair, he accidentally activated the "Successor of Light System" and gained the power to transform into Ultraman.
The main plot revolves around Lin Feng accepting and completing the "Light Mission" issued by the system. The mission has gradually upgraded from the initial "repelling the monsters" and "evacuating the people" to "smashing the alien invasion conspiracy", "fighting the dark Ultraman", and "finding the lost energy of light". Every time he completes a mission, Lin Feng can obtain light points, new Ultraman forms (such as Tiga, Zero, Orb, etc.), Powerful light skills or combat experience.
As he continues to grow stronger, he discovers that the appearance of monsters is no accident, and there is a huge conspiracy led by human resourceful villains behind it. The villain was darkened by past tragedies and tried to "screen" human civilization in extreme ways. Lin Feng grew up from a grassroots student who only wanted to protect the people around him, grew up in crisis after crisis, cooperated with the Global Defense Force, and finally gathered all the power of light, transformed into the strongest form, launched a fateful showdown with the final BOSS, saved the world, and became the true "Proud of Heaven" and the patron saint of the earth.
