Anna is talking about adaptation, but Yang Yi knows it's not that simple.
According to a somewhat complex set of secret codes, what Anna is really saying is just one thing: face-to-face meeting.
Since it's a face-to-face meeting, it might not be so urgent and important, but it has to be highly confidential.
Yang Yi hung up the phone and returned to the others, saying, "I'm going to Europe now, um, nothing major, so you don't need to come with me."
As soon as he spoke, everyone immediately understood that Yang Yi had something to take care of, and naturally, they didn't need to say much; just do what needs to be done.
Another long flight, but luckily the plane Yang Yi and his team were on had intercontinental flight capability; it's just the plane added a temporary task, requiring refueling and maintenance before the next flight.
As for the crew, they have to work a bit harder; Yang Yi can't have his private plane without enjoying any convenience, right?
