This System Is Not a Waste at All

Alas, this system is really miserable! People in time travel have golden fingers, and I am their gold finger in time travel; others in time travel are always prodigal, and I am always said to be a prodigal; others in time travel have a harem, and my system can't even harem myself... Only by turning the wheel to formulate tasks can I have some hope in life! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
