He just wanted to live, but he was forced to become the God Killer.
The time traveler Lu Chen was originally just an intern deacon of the Holy Light Church, and he just wanted to dawdle. Until he activated the "divine sin system" that was deeply bound to his soul - the system collapsed and he was left in a state of despair. The only way to extend life is to hunt down the "sinners" blessed by the Holy Light.
On the much-anticipated prayer day, Lu Chen was forced to publicly kill the gods and embarked on the road to escape. He rescued the saint Elena who was regarded as an "abandoned container" by the church, subdued the knight Renault who was chasing him, and joined forces with the business genius Lance to fight all the way from Gray Mist Town to the Royal Capital and Demon Academy, and established his own free territory.
When heaven and hell sent invitations to him at the same time, and when the Pope frantically activated the Doomsday Array, Lu Chen finally touched the truth of the world - all gods are prisoners, and the law of "belief in gods" is the source of all evil.
"I want every mortal to become his own god."
Use your own power to cut off the divine law, and the correctors of the universe will retreat. The heaven fell, the gods died, and the system was destroyed - and he turned into the light of dawn, forever guarding the world that no longer needs gods.
