"What is the previous epoch?" Lei Gun asked.
"It's the era when we have no history whatsoever, around ten million years ago," Li Shi answered.
"Perhaps that's when our ancestors were born."
"No. A lot of ruins like this one had been found. Many were proven to have predated the current epoch. Which means our civilization started before ten million years ago."
"Then why is there no recorded history?"
"That's why all of us archeologists have been trying to figure out by studying these ruins. That's why, Captain Xu Shi, it is extremely important to give us enough time to study it."
"Tutor Li Shi, I'm not going to repeat it for the fourth time. Please send your complaint through the proper channel. My hands are tied. I can't help you even if I want to."
"But you don't want to," Li Shi said scornfully.
Xu Shi again replied with a shrug.
