Had nothing to begin with

He frowned. Seeing that there was still silence, he said again, "I'm sorry..."

Before Lu Benlai could say the rest of the sentence, "May I ask who you are? Why aren't you speaking?", the other party hung up the phone.

The words that Lu Benlai wanted to say were stuck in his throat.

When he heard the busy tone of "Du du du du"coming from his phone, he felt an inexplicable sense of panic.

"Mr. Lu, it's time for you to board the plane."The flight attendant saw that Lu Benlai was still not moving, so she walked over and reminded him.

Lu Benlai came back to his senses. After putting his phone away, he walked toward the boarding gate. After taking two steps, he stopped again.

For some reason, he felt that the phone call just now was not simple..

After some thought, he took out his phone and returned a call.

After the call was picked up, it rang many times, but no one picked up.
