Rather than feeling sadness or grief when his wife is gone, the narrator instead congratulates himself for concealing the body so well, which is why he looks around triumphantly, satisfied that all his hard work wasn't in vain.
求指教!请问老师,which从句是非限制性定语从句修饰前面整句话the narrator instead congratulates himself for concealing the body so well 吗?
后面的satisfied that是做什么成分?状语吗,修饰he looks around triumphantly?
