Brother, I'm leaving the blockchain first. 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, but you are still reluctant to leave, clinking your bowl with chopsticks, looking forward to the next delicious and sumptuous main course. In the end, you are greeted with a huge bill for this feast. Someone always has to pay for the feast, and this time it's you again.
