My Takeout Box Collects Everything

I really just want to be a free fish delivering food, how come the Ancient God can still choose me? Is it because I'm not lying flat enough? Or am I lying in the wrong position? Saving the world is not my dream. My dream is just to be a delivery man, running in the shower and looking at my watch to feel comfortable every second. Why am I either catching monsters or on the way to catch monsters every day now? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
