Lu Shu waited in front of the buffet restaurant with sheer boredom displayed on his face while inside, Chen Zuan stuffed himself with three days' amount of food. After much discussion, they both agreed that was the best option, to keep him full without losing too much face.
In Lu Shu's opinion, there was nothing to be ashamed of if one could, with his own abilities, eat a fifteen-day portion of food in one shot. It was an "All You Can Eat" buffet after all.
But it was a different case for Chen Zuan, who found it really hard to forgo his high reputation.
Nonetheless, buffets were not cheap either, and the cheapest near them cost 49 yuan. When Chen Zuan was eating inside, Lu Shu had to wait outside with two buns as his breakfast, while he squeezed his brain juice for other money making methods.
As he was not a business genius, Lu Shu had no plans in particular as well. Otherwise, why would he painstakingly go and sell hard boiled eggs back then?
