Magic Grass Believers

The originally eternal sun fell because of the war between the gods. From then on, the continent fell into darkness. However, gradually, humans learned how to use sonic energy to sense and detect the dark environment around them, and thus, a group of noble sonic warlocks were born. Doros, a young man, was born with a strong talent for picking locks. He obtained a magical magic grass by chance, and since then he has slowly embarked on the path of becoming a strong man.
