"Wait for a minute, how can you explore the ruins without me?"
"Words in history are symbols of humanity's wisdom."
Cang Ji is a timid one. He is Narmer's old friend.
He can instruct a party on archaeological techniques such as how to avoid quicksand and how to excavate ruins. Noba Ruins in Debia, for example.
He is deathly afraid of snakes.
He saved Narmer from the monstrous Miramon and uncovers the Rhea Parchment for him in the past.
Academics note his every word because he is a famous expert.
