Actually, the reason why Daoist Xing Yang and Daoist Bai Yun were so composed was not because they saw through life and death.
Their lack of nervousness was entirely because, before they entered the mountain, the two of them cast a divination to test the fortune and misfortune of this mountain excursion.
As a result, the two old Daoists received an outcome: unexpected safety!
What does "unexpected safety" mean? The meaning is too simple—it means that an accident happened, giving you a fright, but the actual result is that nothing happened at all.
Since the divination showed unexpected safety, what was there for the two old Daoists to worry about? Since the final result would be without mishaps, they should eat if it's time to eat, sleep if it's time to sleep, and they didn't take Wu Mei's appearance as any serious crisis.
