"Where did you get this technique from?" Qing Chen pressed.
"According to the records, it was a long time ago. After humanity entered the new civilization era, some hidden cultivation organizations began to emerge," the old man explained, "There have always been two organizations in the Southwest Snow Mountain, one is the Fire Pit, and the other is the organization to which this cultivation technique belongs. They hid in the Hot Spring Valley deep in the mountain until the Federation was established, then they reappeared in the world."
"What were they hiding from?" Qing Chen didn't understand.
The old man glanced at him. "You've seen the textbooks from Li's School, so you should know that human civilization was almost wiped out last time due to the artificial intelligence 'Zero', right?"
"Yes, I know," Qing Chen nodded.
