His Royal Highness is Hungry

My name is Qiu Kui, and I time-traveled! From the wonderful modern world to a poor, ancient village where there's no internet, and even electricity! Worst of all, my parents drowned themselves and my younger sister is physically challenged, and not forgetting the fact that our family is also in debt. I mean, seriously, how can I live under these circumstances! Thank goodness I time-traveled with a bag of groceries and daily necessities... But has anyone time-traveled with items like these? This is ridiculous!
