Brother, I'm stuck in blockchain. All good things must come to an end. This feast has come to its final moment. The delicacies from land and sea have long been eaten, leaving only the leftovers and the mess. The smart people have already eaten their fill and quietly left the table. I was late to realize that I was still reluctant to leave. I took my chopsticks and banged the bowl, fantasizing about the next delicious and sumptuous main course. In the end, I was greeted with a huge bill for this feast. Someone has to pay for the feast, and this time it's me again, Alpaca
