Xu Ying and the others only brought around thirty thousand people, the rest of the several million survivors were brought by the other party.
Lou Fei'Er, Jin Yue, Shi Wanyun, these three women weren't part of Xu Xin's original team. If they're not from other teams within the organization, then they're likely brought to this future a thousand years later by the other party.
"Hmm, that's right. Even survivors from a thousand years ago should have experienced time travel."
Xu Ying nodded thoughtfully and continued to speculate: "Also, the masked man, as the current head of multiple areas of survivors, is very likely the person who originally took these survivors across time."
And the man still inside the treasure chest monster's belly, although also a leader, is only the head of a single, isolated area, a subordinate of that masked man.
