Seeing that Lin Wu looked uneasy, Gu Chengbai quickly added, "But Uncle did not force them to go! When that expedition set out overseas, before they departed, they all knew what they were going to do, and they volunteered!"
Lin Wu queried unexpectedly, "Then do you know what they were going to do?"
Gu Chengbai choked up, subconsciously glancing at Bo Yuting with some defensiveness.
Bo Yuting said irritably, "Well done, Gu Chengbai, turns out you knew more about what happened back then than I did, and here you've been acting clueless, coaxing the information out of me with great difficulty over the years! There's a way to conduct oneself, and you've done it all wrong; it's such a shame I trusted you so much."
Gu Chengbai scoffed, "As if you trusted me that much."
Bo Yuting wanted to roll his eyes but, considering how he must appear in front of Lin Wu, he restrained himself. He then asked, "So you really do know what they were going to do, like... the Underground City?"
