In the most terrifying restricted area of the origin of the doomsday, Chen Guang lived an "ordinary" life: roasting "little lizards" (hell salamanders), and using flashlights (strong flashes) to scare away "big cats" (lord-level monsters)
It wasn't until he "zealously" rescued a dying elite team and was brought back to the human base that he discovered that the world had long been destroyed. What he sees as ordinary "running fast" (teleportation), "good eyesight" (clairvoyance/invisibility), and "knowing a few tricks" (making fire, controlling lightning) are, in the eyes of others, the shocking power of controlling light!
The sunny and cheerful man made countless jokes, but was involved in high-level conspiracies and dusty secrets. When the cruel truth was revealed - he was actually Experiment 001, the source of the doomsday, trust collapsed and swords turned against each other.
Is his light the fire that ignites the doomsday, or the hope that purifies the world? Tearing apart the darkness, he finally became the light of salvation, only to discover that deeper in the earth, an older terror had been awakened...
