If Wu Bin hadn't undergone deep dive training, he might have believed the staff when they said that phrase to him.
But Wu Bin had undergone deep dive training, although he was not quite professional yet, the phrase he heard most from his coach was that deep sea diving was a terrifying thing.
With the state Wu Bin was in now, there was a high probability he would not return from a deep dive.
Nightingale also noticed that Wu Bin's expression was off, and she told the staff, "Okay, stop fooling him, he has undergone this training."
Upon hearing Nightingale say that, the staff's attitude changed immediately.
He helped Wu Bin properly wear his equipment and then said, "Wu Bin, if you encounter danger... good luck then."
Wu Bin: ...
Man, this isn't the time to leave your sentence hanging!
Do you know how anxious that makes me?
After ensuring Wu Bin's equipment was properly worn, the two staff members didn't waste words, patted his shoulder, and turned to leave.
