Sign in and Get a Trump Card, I Ended the Dark Age

This is a world shrouded in darkness, where humans are struggling to survive under the gluttony of dark creatures. Only the life source fire of the fire holder can illuminate the darkness, contend with monsters, and protect one side. Ordinary people are reduced to cannon fodder and reproductive tools, working endlessly. Chen Yu, who traveled through time and became a fire bearer, originally thought that he would also embark on the dangerous path of a bloody fight with dark creatures. Until the endless hole card system starts. "Congratulations, master, for signing in and receiving immortal-level core equipment!" "Congratulations to the owner for signing in and receiving the One-Hit Star Invincibility Experience Card!" "Congratulations, master, for signing in and receiving the Dark Goddess Slavery Scroll." "..." "It seems that we don't need a few trump cards to end the entire Dark Age!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
