[No system + weird + super powers + decisive killing + daily love + single female protagonist + cool writing + slightly forced]
My name is Dangtian, and my father hopes that I will eradicate all evil in the world and eliminate all sins.
Unexpectedly, when I was 10 years old, I traveled through time and entered a strange world. In that world, I didn't have enough to eat, and I had to worry about becoming food at any time.
Fortunately, I met a kind-hearted Weird, but it died to protect me, and I inherited his power.
When I was 20 years old, I actually came back, but something strange happened, and it was already 10 years ago.
