Civilized beings, when going through many significant events, all seek a sense of ritual.
This ritualistic sentiment is manifested in small ways, perhaps as in the various rules of courtship between men and women, or setting off firecrackers for a store's grand opening. In larger ways, it is reflected in various customs of festivals or the ancient emperor's ascent to the throne.
Rituals gradually give rise to rules.
The same applies to the excavation of the Pyramid's hierarchical layers, an event comparable in significance to an emperor's coronation for the people.
Those who have the privilege to witness it will also leave their mark in the entire history of humankind.
That was Li Xiaoyu's intention in inviting Tang Xian.
"By the way, I'm feeling a bit uneasy, can I bring a child along?" Tang Xian asked.
"Tang Xiaojiu?" Li Xiaoyu inquired.
"That's right."
"Bringing a child makes you feel at ease?"
"Yes, she's my lucky charm," Tang Xian came up with an excuse.
