The person asked, "Why are you going out?"
Ling Zhenfei said, "I'm just answering the phone, you see, it's still ringing."
The person said, "It's just answering the phone, you can do it here."
Ling Zhenfei said, "I have a headache and I'm used to going out to take calls."
By saying this, Ling Zhenfei wanted to quickly bring the matter out in the open. Now, whether it's Kudo Nanting's side or the opponent's side, everyone is waiting for something, so neither side has made a move.
Ling Zhenfei couldn't waste all his time on this, so he wanted to push things forward quickly, and therefore chose this approach.
Ling Zhenfei had been talking with Kudo Nanting for too long, making it hard for people not to suspect something.
They suspected Ling Zhenfei must have learned something, or was even helping Kudo Nanting.
Needing to step out to take a call was definitely suspicious, possibly to assist Kudo Nanting in making arrangements, so the people would not let Ling Zhenfei leave.
